ABSTRACT:
A speaker apparatus includes a speaker frame, an acoustic vibrating plate movably supported on the speaker frame, and a magnetic driver formed in the speaker frame for vibrating the acoustic vibrating plate. The magnetic driver is connected such that it may vibrate different portions of the acoustic vibrating plate independently. The acoustic vibrating plate of the speaker apparatus may vibrate with the same phase, thereby increasing sound pressure and improving acoustic efficiency.
