Description High-low sound combined type sound cavity structureTechnical Field
The utility model relates to a stereo set sound cavity design technical field especially relates to a high bass combination formula sound cavity structure.
Background
A speaker, also called a "horn", is a very common electroacoustic transducer, which is found in electronic and electrical devices for generating sound. The speaker structure is as follows: consists of a permanent magnet, a coil and a conical cone. The working principle of the loudspeaker is as follows: the electric coil is electrified to generate magnetism and then acts with the permanent magnet, when the current direction is as shown in the figure, the electric coil and the permanent magnet attract each other, and the paper cone is driven to move leftwards by the electrified coil; when the current direction changes, the coil drives the paper cone to move rightwards; the magnitude of the current affects the amplitude of the cone vibration, so that the speaker produces a sound that varies with the current. Loudspeaker application: the radio, the television and the loudspeaker box are all provided with loudspeakers. The electrodynamic type speaker sound production principle is through the coil motion in magnetic field of alternating current signal, makes the vibrating diaphragm vibration that links to each other with the voice coil loudspeaker voice coil to drag and link the cone vibration, the rethread air medium, with the sound wave conveying away. In a standard way, it is a component that converts an electrical signal into sound. The strength of electric current, the height of frequency just can make the speaker send different sound, and in daily life, the use of speaker must combine together with the audio cavity, and in the design process, how to make the structure of product more reasonable, the quality guarantee, the audio improves to some extent scheduling problem, is the very real problem that research and development personnel faced, awaits further solution.
