Abstract
The utility model discloses an audio sound generator, which comprises a U-shaped iron, a high-intensity magnet, a washer, a silica gel cushion, a vibration sound box coil and a vibration base. The vibration sound box coil comprises a coil bracket, coil windings and brocade silk threads. The coil windings are wound on the coil bracket. Anodes of one group of coil windings are connected with an anode of one passage of a power amplifier through the brocade silk threads. Cathodes of one group of coil windings are connected with a cathode of one passage of the power amplifier through the corresponding brocade silk threads. The coil bracket of the vibration sound box coil is provided with two or more groups of coil windings. The audio sound generator has a simple structure. Under the condition of the same working voltage, the power output by the audio sound generator disclosed by the utility model is one or a plurality of times of the power output by other audio vibration generators. The audio sound generator is particularly suitable to be used in the place supplied with power by a USB (Universal Serial Bus).
