摘要： An acoustic exciter comprises a suspension made of an elastic material, which is coupled to the opening part of a frame, and a vibrator to which a voice coil disposed in the magnetic gap of a magnetic circuit connected to the suspension is coupled. An elastic body is so disposed between the frame and the vibrator as to be pressed against the frame and the vibrator. Thereby, the exciting efficiency of the vibrator can be increased, and the performance and tone quality of the acoustic exciter can be improved.
