201039657 六、發明說明： 1 【發明所屬之技術領域】 本發明涉及具有音頻數位接口的多媒體音響系統，特 別涉及具有USB外置音效卡或IEEE 1394外置音效卡並由 電腦或光碟遊戲機供電的數位多媒體音響系統，屬於電腦 的周邊電聲設備。 【先前技術】 本發明是在本發明人已經提出的PCT/CN2008/072668 0 等專利申請的基礎上經修改後作出的。 具有音頻數位接口的多媒體音響系統，包括具有USB 外置音效卡或IEEE1 394外置音效卡的多媒體音響系統是 一種先前技術。 例如’微軟公司在上世紀末就推出了由外置電源供電 的DSS 80型USB音響系統。 PHILIPS公司於2006年推出的DGX320型音響系統， 每個音箱内設有一個1英寸高音揚聲器，一個2英寸全頻 Ο 帶揚聲器和一個無源低音輻射器，由PC的USB接口提供 電源，其輸出功率為2x1 W，頻率回應範圍為i〇〇Hz〜20KHZ。 2006年3月，日本EVERGREEN公司推出的dn· MPS100型音響系統，包含二個3英寸口徑的揚聲器，一個 安裝在面板上的USB接口和一個安裝在音箱背後的Mp3 decoding類比數位轉換器及箱内的收音機電路。其音頻輸 入功率為2x7W，釆用隨附的AC適配器由電力網獨立供電。 2007年1月，YAMAHA公司于CES展會上推出一款 NX-U10型USB音響系統，採用二個】5英寸口徑的mi… 3 201039657 < 揚聲器’通過“充電電容放大器，，技術和SR_Bass低音增 強技術，將筆記本PC USB接口提供的能量儲存在一組電 容器的極板上藉以滿足低音頻強勁輸出時對功率容量的爆 發性需求。其頻率響應範圍為9〇hz〜20KHZ。 但是’大量基於USB音頻類比數位轉換器（DAC)和 2〜4個Mini揚聲器以及一組數位或類比功率放大器構成的 USB Mini音響系統曾經充斥於市場。就總體而言，這類產 '«的音質差、音量小，無法滿足消費者的使用要求。 Ο 眾所周知，PC USB接口的輸出電壓是DC 5V±5%，輸 出電流是500mA。也就是說，每個USB接口可以提供的額 疋連續功率只有2.5W。而一個2英寸口徑揚聲器的額定連 續輸入功率為3~5W’其SPL值通常為83dB/1w/1m左 右。一個1.25 ~ 1_5英寸口徑揚聲器的額定連續輸入功率 大致為1〜3W’其SPL值通常為79〜82dB/1W/1m左右。 一個3英寸口徑揚聲器的額定連續輸入功率大致為 5 10W，其SPL值通常為85dB/1W/1m。3英寸口徑揚聲 〇 器雖然具有較低的諧振頻率Fo，其低音頻段的電聲還原品 質比2英寸以下的Mini揚聲器要好得多。但是，音響製造 商寧願選擇音質相對差一些的2英寸或更小口徑的揚聲器 作為USB音響的發聲單元。其原因是：電腦usb音響系統 功率放大器輸出的2x1W左右電功率很難推動一對3英寸 口徑揚聲器正常工作並獲得足夠的音量和良好的音質。 一般而言，2英寸口徑揚聲器的電聲轉換效率只有 〇· 125 %。也就是說：當這個揚聲器輸入1 w電功率時，只 有0.00125W的電能被轉換成有用的聲能，其餘〇 99w電 4 201039657 _ 能都被轉換成人們不需要和有害的熱能而白白浪費掉。與 我們常見的白熾燈的能量轉換效率7 ~8 %相比較，2英寸 揚聲器的效率大約只有白熾燈效率的1 /5〇左右。 所以，現有的主流揚聲器即動圈式揚聲器（以下簡稱 為揚聲器），是20~21世紀全球範圍内能量轉換效率最低 而用途最廣泛的人類社會基礎電氣產品： 其一，在全世界，除US5849760專利案外，幾乎所有 商品化生產的揚聲器都只有一個磁隙和一個線圈。當這個 〇 線圈接通音頻電流時，線圈在磁隙磁場的交互作用下根據 弗萊明左手疋則產生一個電動力F，推動揚聲器振膜作往復 式/舌塞運動，揚聲器因振動空氣而發聲。但是，當這個線 圈作往復式活塞運動時，磁隙内的永磁磁力線又垂直切割 這個線圈，在線圈内感應得到一個弗萊明右手定則規定的 發電機電勢，這就是通常所說的反電動勢。這個反電動勢 與揚聲器線圈内的音頻信號疊加後造成揚聲器的失真。一 般說來，揚聲器線圈的振幅愈大、加速度愈大、音頻信號 〇 電流的頻率愈低，反電動勢的幅值也愈大，所引起的失真 也愈大。所以，先前技術受到反電動勢失真的制約而無法 提高揚聲器的Μ。其三，先前技術可以實施成功一個全 頻帶(FuM Range”小口徑揚聲器。但是，先前技術無法 使這種全頻帶揚聲器具備廣大消費者普遍接受的價格並實 現批量工業生產。其根本原因在於：揚聲器的阻抗是揚聲 器工作電流頻率的一個函數：頻率愈低阻抗愈低，頻率愈 向阻抗愈高。對於每一個傳統的單磁隙單線圈揚聲器，其 線圏中流過的高音頻電流有效值比低音頻電流要小得多。 5 201039657 • 所x這個揚聲器在高音頻段產生的聲壓比低音頻段有明 顯的減V。對於小於3英寸口徑的揚聲器而言，由於揚聲 器振動系統的品質較小’人們可以借助技術手段予以彌 :。但此類小口徑揚聲器的諧振頻率F。必然偏高，很難獲 得令人滿意的低音頻電聲還原效果。對於3英寸以上口徑 的揚聲器而言’隨著單元直徑的加大，F〇將向低音頻段下 潛從而改善揚聲器的低音頻還原品質。但是，此類揚聲器 的振動系統品質有所增加，揚聲器在高音頻段的spL值將 0 在5 1 〇 KHz及以上頻段產生大的陡降。所以，現有的多媒 體音響系統，常常設置—個高音揚聲器和一個中低音揚聲 器來滿足消費者對Fo〜20KHz頻段的全音域需求。當然， 為了均衡這二個揚聲器的工作還必須增加一個分頻器。而 分頻器的引入又進一步增加了音響系統的能耗和失真度。 其二’ US5849760專利案由於其結構原因無法在中小口徑 揚聲器例如應用面最廣泛的1/2 ~ 8英寸口徑揚聲器範圍 内得到推廣應用。 Ο 其四’儘管如此，PC的USB音響系統還是具有一些 公認的優點0例如： (1) 採用USB外置音效卡，可以徹底擺脫電腦機箱内變 壓器和電風扇所產生的電磁波干擾； (2) 基於PCM/PWM音頻數位技術的數位類比/類比數 位轉換器和D類音頻功率放大器或基於DPPTM專利技術的 1Bit △—Σ數位類比轉換技術的T類音頻功率放大器，與 類比音頻系統十分複雜的濾波器、R/C隔直流網路和AB類 功率放大器相比較，在抗干擾、放大器效率、信噪比、動 6 201039657 態範圍等方面都比類比音頻系統有更好的表現； ' (3)到目前為止，電腦的PC丨主流音效卡只有16 Bit的 轉換精度，而不少USB Mini音箱内的USB單工音效卡， 其DAC卻往往具有20 Bit的轉換精度； (4)USB通用串列匯流排雖然比PCI匯流排的等級 低，但隨著CPU性能的不斷提高，尤其是雙核和4核CPU 的湧現以及CPU功能的不斷強化，USB2.0接口標準的充 分普及和USB3.0接口標準的即將頒行，基於USB/或 0 丨EEE1394(含1394.b等衍生產品）接口技術的數位多媒體 音響系統將成為今後必然的發展趨向。 有鑒於此，發明人從1997年開始提出了 一系列發明專 利方案企圖改變上述極端不合理的現狀。它們主要包括： (A) WO 01/15493 專利族的授權專利 CN00122197.3、 US6795564、CN200520035371 .X ' CN200620033128.9 和已經公開的專利中請 JP特表 2003-531508、 US20050099255 、 CN200510091936.0 、 〇 CN200610020317.7 ； (B)WO 99/31931專利族的授權專利： CN991 14781.2 ' TW88109796 ' CN00222469.0 ； (C)尚未公 開 的 CN200710181973.X 、 CN200710123821.4 、 CN200720126871.3 、 CN200810065384.X 和 CN200820092177.9 等專利申請。 為撥冗起見，詳細的内容請參閱上述專利文獻而不再 重複。 【發明内容】 201039657 • 本發明的第一個目的是克服技術偏見和先前技術的不 足之處，提供—種由USB/或IEEE1394接口供電、使用具 有電阻負載特性或近似於電阻負載特性的單振膜全頻帶多 隙多線圈揚聲器構成一種具有高效節能、高效節材和高 保真品質的2.0聲道數位多媒體音響系統。 本發明的第二個目的是克服技術偏見和先前技術的不 足之處，提供—種由USB/或IEEE1394接口供電、使用具 有電阻負載特性或近似於電阻負載特性的$振膜全頻帶多 〇 ㈣多線圈揚聲器構成-種具有高效節能、高效節材和高 保真品質的2_1聲道數位多媒體音響系統。 本發明的第三個目的是克服技術偏見和先前技術的不 足之處提供一種由獨立的交直流電源或磁碟電源接口供 電、由USB/或IEEE1 394接口提供音頻數位信號、使用具 有電阻負載特性或近似於電阻負載特性的單振膜全頻帶多 磁隙夕線圈揚聲器構成一種具有高效節能、高效節材和高 保真質的4_ 1〜7.1聲道數位多媒體音響系統。 Ο 本發明的第四個目的是克服先前技術的不足之處，對 先則的多磁隙多線圈揚聲器的技術特徵作出進一步的改進 和限疋。消除揚聲器的發電機效應和反電動勢，提供一系 列具有超鬲效率和高保真品質的全頻帶揚聲器，尤其是提 供種具有電阻負載特性或近似於電阻負載特性的超高效 率和低失真度的重低音揚聲器。 本發明的目的是這樣實現的： 一種具有音頻數位接口的多媒體音響系統，包括電腦/ 或光碟遊戲機PS2的至少—個υ3^σ/或丨ΕΕΕ1394接口 8 201039657 /或同軸電纜接口 /或光纖接口，一組與USB/或丨EEE1394 接口連接的2.0聲道外置音效卡及與之匹配的d類/或丁類 音頻功率放大器丨C晶片，一組與所述2.0聲道外置音效卡 及所述音頻功率放大器匹配的控制保護電路/或微處理器丨c 晶片，一對左右聲道音箱，其特徵是：所述2·〇聲道外置音 效卡、所述IC晶片及與之關聯的SMD表面貼裝元件/或集 成在一起的CMOS電路、指示所述外置音效卡工作狀態的 LED信號燈、所述音頻功率放大器的音量調節裝置均安裝 0 在/或通過電線和插接件連接到PCB板上，所述PCB板固 定安裝在所述左聲道音箱内/或音箱支架内，所述led信號 燈及所述音量調節裝置固定在所述左聲道音箱面板/或音箱 支架上’所述PCB板/或所述左聲道音箱面板上還設有一個 與所述接口匹配的插座/或通過一根接口延長線的插頭與電 腦/或光碟遊戲機PS2的所述接口相連接，所述右聲道音箱 的面板上也設有一個音頻插座，一根音頻電纜將所述左右 聲道音箱連接成為一個2.0聲道音響系統； Q 所述2.0聲道外置音效卡至少具有一組單工的16〜48201039657 VI. Description of the Invention: 1 Technical Field of the Invention The present invention relates to a multimedia audio system having an audio digital interface, and more particularly to a USB external sound card or an IEEE 1394 external sound card and powered by a computer or a video game console. The digital multimedia sound system belongs to the peripheral electro-acoustic equipment of the computer. [Prior Art] The present invention has been made on the basis of the PCT/CN2008/072668 0 and the like which have been proposed by the present inventors. A multimedia audio system with an audio digital interface, including a multimedia sound system with a USB external sound card or an IEEE 1 394 external sound card, is a prior art. For example, at the end of the last century, Microsoft introduced the DSS 80 USB audio system powered by an external power supply. PHILIPS introduced the DGX320 audio system in 2006. Each speaker has a 1-inch tweeter, a 2-inch full-range speaker and a passive bass radiator. The USB interface of the PC provides power and its output. The power is 2x1 W and the frequency response range is i〇〇Hz~20KHZ. In March 2006, Japan's EVERGREEN launched the dn·MPS100 audio system, which includes two 3-inch speakers, a USB interface mounted on the panel, and an Mp3 decoding analog-to-digital converter mounted in the back of the speaker. Radio circuit. Its audio input power is 2x7W, which is independently powered by the power grid using the included AC adapter. In January 2007, YAMAHA introduced a NX-U10 USB sound system at CES, using two [5-inch] diameter... 3 201039657 < Speaker 'passed by 'Charge Capacitor Amplifier, Technology and SR_Bass Bass Enhancement Technology, the energy provided by the notebook PC USB interface is stored on the plates of a group of capacitors to meet the explosive demand for power capacity when the low audio output is strong. The frequency response range is 9〇hz~20KHZ. But 'large amount of USB based The USB analog audio system consisting of an audio analog-to-digital converter (DAC) and 2 to 4 Mini speakers and a set of digital or analog power amplifiers has been used in the market. In general, the sound quality and volume of such products are small. Can not meet the consumer's use requirements. Ο As we all know, the output voltage of the PC USB interface is DC 5V ± 5%, the output current is 500mA. That is, each USB interface can provide a front-end continuous power of only 2.5W. A 2-inch calibre speaker has a rated continuous input power of 3~5W', and its SPL value is usually around 83dB/1w/1m. A 1.25 ~ 1_5 inch calibre speaker The continuous input power is approximately 1~3W', and its SPL value is usually about 79~82dB/1W/1m. A 3-inch calibre speaker has a rated continuous input power of approximately 5 10W, and its SPL value is usually 85dB/1W/1m. Although the 3-inch caliber speaker has a lower resonant frequency, the acoustic reduction quality of the bass band is much better than that of a Mini speaker below 2 inches. However, the audio manufacturer prefers to choose a 2-inch with a relatively poor sound quality. The smaller-caliber speaker acts as the sounding unit for the USB audio. The reason is that the 2x1W power output of the computer's usb audio system power amplifier is difficult to push a pair of 3-inch caliber speakers to work properly and get enough volume and good sound quality. In other words, the electroacoustic conversion efficiency of a 2-inch calibre speaker is only 〇·125%. That is to say: when this speaker inputs 1 kW of electric power, only 0.00125 W of electric energy is converted into useful acoustic energy, and the rest 〇99w electric 4 201039657 _ Can be converted into people who don't need and harmful heat to waste. Compared with the energy conversion efficiency of our common incandescent lamps is 7 ~ 8 % The efficiency of a 2-inch speaker is only about 1/5 of the efficiency of an incandescent lamp. Therefore, the existing mainstream speaker, that is, a moving coil speaker (hereinafter referred to as a speaker) is the lowest energy conversion efficiency in the world in the 20th to 21st centuries. The most extensive human society basic electrical products: First, in the world, except for the US5849760 patent, almost all commercially produced speakers have only one magnetic gap and one coil. When this coil is connected to the audio current, the coil is magnetic. Under the interaction of the gap magnetic field, according to Fleming's left handcuffs, an electric power F is generated to push the speaker diaphragm to reciprocate/tongue movement, and the speaker emits sound due to the vibration of the air. However, when the coil is moved by a reciprocating piston, the permanent magnet magnetic field in the magnetic gap cuts the coil vertically, and a generator potential specified by Fleming's right-hand rule is induced in the coil. This is known as the back electromotive force. . This back electromotive force is superimposed on the audio signal in the speaker coil, causing distortion of the speaker. In general, the larger the amplitude of the speaker coil, the greater the acceleration, the lower the frequency of the audio signal 〇 current, the larger the magnitude of the back electromotive force, and the greater the distortion caused. Therefore, the prior art is limited by the back electromotive force distortion and cannot improve the noise of the speaker. Third, the prior art can implement a full-band (FuM Range) small-caliber speaker. However, the prior art cannot make such a full-range speaker at a price that is generally accepted by consumers and achieves mass industrial production. The fundamental reason is: speaker The impedance is a function of the operating current frequency of the speaker: the lower the frequency, the lower the impedance, and the higher the frequency, the higher the impedance. For each conventional single-gap single-coil loudspeaker, the high audible current ratio of the high-current current flowing in the coil is lower. The audio current is much smaller. 5 201039657 • The sound produced by this speaker in the high-frequency section has a significant V reduction from the bass band. For speakers smaller than 3 inches, the quality of the speaker vibration system is small. It can be done by means of technical means: but the resonant frequency F of such small-caliber loudspeakers is inevitably high, and it is difficult to obtain a satisfactory low-audio electroacoustic reduction effect. For a speaker with a diameter of 3 inches or more, 'with the unit As the diameter increases, F〇 will dive into the bass band to improve the low-tone reproduction of the speaker. However, the quality of the vibration system of such speakers has increased, and the spL value of the speaker in the high-frequency section will have a large steep drop in the frequency band of 5 1 〇KHz and above. Therefore, the existing multimedia audio system is often set up. The tweeter and a mid-woofer to meet the consumer's full range requirements for the Fo~20KHz band. Of course, in order to balance the work of these two speakers, a crossover must be added. The introduction of the crossover further adds the audio. The energy consumption and distortion of the system. The 'US5849760 patent case cannot be popularized for small and medium-sized caliber speakers such as the most widely used 1/2 to 8 inch caliber speakers due to its structure. Ο The fourth 'but nevertheless PC's USB audio system still has some recognized advantages. 0 For example: (1) Using USB external sound card, you can completely get rid of electromagnetic interference caused by transformers and electric fans in the computer case; (2) Based on PCM/PWM audio digital technology Digital analog/analog digital converter and class D audio power amplifier or 1Bit △-Σ based on DPPTM patented technology Digital analog conversion class T audio power amplifier, compared with analog audio system very complex filter, R / C DC network and class AB power amplifier, in anti-interference, amplifier efficiency, signal to noise ratio, dynamic 6 201039657 The range of states and other aspects are better than the analog audio system; ' (3) So far, the computer PC's mainstream sound card has only 16 Bit conversion accuracy, and many USB simple sound card in USB Mini speakers The DAC often has a conversion accuracy of 20 Bits; (4) The USB universal serial bus is lower than the PCI bus, but with the continuous improvement of CPU performance, especially the emergence of dual-core and 4-core CPUs and CPU Continuous enhancement of functions, full popularization of USB2.0 interface standards and forthcoming of USB3.0 interface standard, digital multimedia audio system based on USB/or 丨EEE1394 (including 1394.b and other derivative products) interface technology will become the future The inevitable development trend. In view of this, the inventors began in 1997 to propose a series of invention patent programs in an attempt to change the above-mentioned extremely unreasonable status quo.

Thirteenth A and Thirteenth B show the wiring diagram of the three-magnetic three-coil speaker coil circuit (1), and the fourteen-dimensional A and four-fourth B show the three-magnetic three-coil speaker coil Circuit principle wiring diagram (2), fifteenth 29 201039657 The figure shows the wiring diagram of the circuit principle of the four magnetic gap four coil speaker coil. For a description of the principle of the work, please refer to the corresponding drawings and specifications of the CN200820092177.9 patent application document and the description will not be repeated. It goes without saying that, according to the contents described in the embodiment, it is easy for a person skilled in the art to implement a multi-magnetic gap multi-coil inner magnetic speaker that successfully succeeds four or more magnetic gaps and four or more coils by increasing the number of plates and magnets. As for the wiring circuit diagram of the speaker circuit of four or more magnetic gaps and four or more coils, the simplest way is to connect all the turns of the turns together by two vertically disposed copper foils, as described by the inventors in the CN2437092Y patent. That way. At this time, the equivalent impedance and the back electromotive force will become quite insignificant. The ninth diagram shows the magnetic gap magnetic field distribution of the prior art outer plate. The ninth diagram is essentially a four-solid node of the sixth embodiment of the present invention. Magnification is not intended. The 7L piece 1 03A is an outer plate of the speaker, and one-half of the horizontal bisector of the same degree of axial direction is the z-z axis. As can be seen from the ninth figure, the outer surface of the electrode plate 1Q3A at this time is flush with the end face of the ring-shaped magnetic disk 113, that is, the H value of the HkTF is =0. The permanent magnet magnetic line 1 991 in the annular magnetic gap 11QA exhibits an asymmetrical state on both sides of the Z--Z axis. If the coil 1 〇 9A shown in the sixth figure is inserted in the magnetic gap, the horizontal bisector of the one-half axial height of the coil is delivered to the z...z, and the z-axis overlaps. When the audio current flows through the coil 109A, the shape of the permanent magnet magnetic field distribution at the upper and lower portions of the axis is different from that of the initial and the τ u迥曰, _ η ^ ^ axis, and thus the density of the coil 109 is eight. --- The upper and lower parts of the Z axis will produce different electric power F, f @ * to make the coil twisted and deformed to increase the distortion of the speaker. 30 201039657 The tenth graph shows a schematic diagram of magnetic flux lines of force distribution of the outer plates of the present invention. At this time, the H>0' threshold is closely related to the diameter of the speaker, the geometry of the magnet, and the magnetic energy product. It can be seen from the tenth figure that on both sides of the Ζ--Ζ axis money, the permanent magnetic field lines 1 991 are always distributed symmetrically, and the prior art defects shown in the ninth figure are corrected. The eleventh drawing shows a schematic diagram of the working principle in which the counter electromotive forces in the symmetric magnetic circuit and the symmetrical coil circuit of the present invention cancel each other out. Ο where the eleventh figure shows a waveform of a sine wave audio current signal input to a coil on one side of the axis of the speaker X...X (for example, the component ι〇9Α of the sixth figure) in the embodiments of the present invention and The back electromotive force spike waveform induced during the zero crossing. Figure 11B shows the waveform of a sine wave audio current signal input to a coil on the other side of the speaker X---X axis (e.g., element 109B of the sixth figure) in the embodiment of the present invention and its zero-crossing point A counter-electromotive force spike waveform obtained by symmetry is induced. The sinusoidal audio current signal in the above coil has a phase angle of 180 degrees, in accordance with the implementation specifications of the present invention. Fig. 11C shows a counter electromotive force spike waveform which is induced in a coil on the side of the speaker X ... X axis (e.g., element 1 〇 9A of Fig. 6) in the embodiment of the present invention. The eleventh figure D thousand, ^ M does not show the back electromotive force spike waveform induced in the coil of the other side of the X---X axis (for example, the sixth figure, the element 109B) in the embodiments of the present invention. > / The two coils on both sides of the axis are wound in opposite directions, so the back electromotive force induced in a coil is offset by zero with a phase angle of 180 degrees and is approximately zero. ~ To better illustrate the problem of back-EMF in the speaker coil, 31 201039657 The tenth figure shows the prior art single-fluid single-coil loudspeaker audio current and back-EMF working principle is not intended. The component is an audio signal source, the component 2 is a conventional single-gap single-coil speaker, the component 2 is an equivalent generator potential of a single-gap single-coil speaker, that is, a counter electromotive force signal source, and the component 3 is a speaker generator state operation. The equivalent load at the time. From the lower diagram of the twentieth diagram, when the «single-magnetic-single-single coil speaker is turned on the audio signal source, an instantaneous audio current flows through the speaker, and the speaker generates a corresponding electric power F'. The direction is as shown. At this time, it can be seen from the 〇°°卩 diagram of the twentieth diagram. Since the coil of the single-flux single-coil speaker acts as a reciprocating piston under the action of the electric power F and vertically cuts the permanent magnet magnetic line in the magnetic gap, it becomes a hair. Motor 2, 'The equivalent load is component 3, the generator potential, that is, the back electromotive force flow direction is shown as E, which has a phase angle of 180 degrees with the audio current 丨 in the coil (ignoring the influence of parasitic capacitance and inductance) Causes distortion of the audio signal. The twentieth-figure shows the operation principle of the multi-magnetic gap of the symmetrical magnetic circuit and the symmetrical coil circuit of the present invention, and the working current and back electromotive force of the coil speaker are shown. It can be seen from the lower diagram of the twenty-first figure that when the speaker is turned on the source (four) source 21, two instantaneous winding audio currents, two symmetrical lines, flow through the two reversely wound speaker symmetrical coils and 23B. The electric power FA and FB are generated in the same direction, and the resultant force f is formed in the same direction. _ The upper diagram of the ten-picture can be seen as: due to the multi-magnetic gap multi-coil loudspeaker, the second coil is called the reciprocating piston movement under the action of the electric power F and the permanent magnet magnetic line in the vertical magnetic gap becomes two equivalent haircuts. a Motors 23A, and 238, because the two coils are opposite in direction and have a symmetrical magnetic circuit coil circuit characteristic, the generator potentials of the two coils are equal in absolute value 聃32 201039657 has a phase angle of 180 degrees, anti-EM man When tA and ΕΒ flow through the equivalent load 2, they cancel each other out or approximately cancel. Fig. 18 is a view showing the mounting of the magnetic core and the bracket in the present invention. Fig. 19 shows a schematic view of the installation of the four magnetic gap four-coil inner core and the bracket of the present invention. # 15磁 ο This is the installation diagram of the magnetic circuit structure separated from the seventh and eighth figures. It can be seen from the foregoing that the present invention proposes an internal magnetic speaker technology scheme having three magnetic gap three coils, four magnetic gap four coils and even more magnetic gaps and more coils. In these speaker solutions, the magnets mounted on both sides of a circular plate have the same polarity. . . , so as to constitute at least a pair or a pair of the above-mentioned repulsive magnets and the magnetic circuit core β Dang Tian When the magnets have a large geometry and a high magnetic energy product, the repulsive force between the repulsive magnets becomes very large, which not only increases the difficulty of the core fixing process, but also ensures reliable operation of the speaker. Bring new instability. A new technical solution is shown in the eighteenth and nineteenth embodiments: a central shaft hole having an equal projection area is provided on the axis of the plate and the magnet, and the speaker is made of a non-magnetic material. The axial portion of the bracket 381 $ 681 is also provided with a central shaft hole equal to the shadow area and/or a matching screw hole, and a non-conductive material such as 1Cr 9Ti is not recorded. a fastener or a pressure plate 372 < 672 formed through the shaft hole and using a non-magnetic material 2 matched to the plate to apply sufficient pressure to the plate and the magnet They are knotted and fixed on the ten-seat face 31180 or 61180 in the bracket of the speaker. Figures 18 and 19 show a static pressure exerted on the core by means of a screw - or 33 201039657 6711 and a set torque of a nut 375 or 675. Based on the well-known technique: as long as the illustrated fastener 3710 or 671 is rotated 180 degrees and the central shaft hole of the bracket 381 or 681 is changed to a screw hole matching the screw, by adjusting the torque of the nut 371 or 671 Static pressure is applied to the platen 372 or 672, which may also be adhesively secured to the inner land surface 31180 or 61180 of the bracket 38 or 68 by the fasteners 371 or 6710. Based on the well-known technique: if the non-magnetic stainless steel fastener 3710 or 6710 is replaced by a semi-circular aluminum rivet stud, the tail of the rivet can be riveted to the pallet 372 or 672 by appropriate pressurization. In the above, the magnetic core can also be adhesively fixed on the inner convex platform surface 31彳8〇 or 6118〇 of the speaker bracket 381 or 681.
