Abstract
The frame of a speaker is divided into a first frame part and a second frame part. The outer circumferential edge of the suspension holder is sandwiched between the surfaces of the first and second frame parts. This structure can reduce rolling of the diaphragm and harmonic distortion of the speaker.
