Abstract

The present invention provides a speaker device having a support structure with a support body provided with a sound chamber and an annular sound hole. The speaker device further includes an ultrasonic sound emitting unit for emitting symmetrical ultrasonic waves, and a demodulation structure with a diaphragm and multiple fixed parts. The diaphragm is spaced apart from the sound hole. The ultrasonic waves emitted by the ultrasonic sound emitting unit drive the demodulation structure to vibrate, adjusting the size of the gap. Compared with the prior art, the speaker device of the present invention has high sound wave demodulation efficiency, good improvement in vibration system amplitude, and excellent acoustic performance.
