Claim Text:
1. A sound generator, comprising: a diaphragm having a first sub-diaphragm, and a second sub-diaphragm connected with the first sub-diaphragm; a voice coil having a first voice coil corresponding to the first sub-diaphragm, and a second voice coil corresponding to the second sub-diaphragm; a signal source for outputting a left channel signal L and a right channel signal R; a first high-pass filter for receiving the left channel signal L and outputting a first high frequency signal; a first low-pass filter for receiving the left channel signal L and outputting a first low frequency signal; a second high-pass filter for receiving the right channel signal R and outputting a second high frequency signal; a second low-pass filter for receiving the right channel signal R and outputting a second low frequency signal; a first mixer for mixing the first low frequency signal and the second low frequency signal, and outputting a low frequency signal; a pair of second mixers for mixing the low frequency signal and the first high frequency signal for outputting a first driving signal, and mixing the low frequency signal and the second high frequency signal for outputting a second driving signal; the first driving signal being transmitted to the first voice coil for driving the first sub-diaphragm to vibrate, and the second driving signal being transmitted to the second voice coil for driving the second sub-diaphragm to vibrate.
