Links Landscapes Abstract

This invention is about a kind of speaker, in which a pair or more than a pair of repulsive magnets are installed at both sides of a ring-shaped plate. A corresponding ring-shaped plate is installed individually at the other pole surface of magnets stated above. Three or more than three magnetic gaps are formed in between the lip fringe, which extends convexly in radian direction, of three pieces or more than three pieces of ring-shaped plates and the external peripheral surface of a ring cylinder-like magnetic body that is coaxially installed. Voice coils are inserted into the magnetic gaps, in which the winding direction of voice coil and current direction flowing through voice coil are stipulated so as to make voice coils generate the same direction of electric force at the same time. When the speaker has a pair of repulsive magnets and repulsive magnetic circuits with totally symmetrical magnetic energy, the coil number, amount of inductance and wire connection type of voice coil are set and the speaker stated above has pure resistance load characteristic.
