Abstract
A speaker includes a frame, a vibration system including a diaphragm and a voice coil driving the diaphragm to vibrate and emit sounds, and a magnetic circuit system. The diaphragm includes a dome and a suspension surrounding the dome, the dome includes a first dome and a second dome stacked on the first dome, the second dome is smaller than the first dome and a projection of the second dome along a vibration direction of the diaphragm is entirely located on the first dome, the first dome is a metal dome, or a plastic dome, or a composite dome comprising a metal layer and a foam layer, the second dome is a metal dome, or a plastic dome, or a composite dome with a metal layer and a foam layer. Compared with the related art, the speaker disclosed by the present disclosure has a high strength of the dome.
Claims5
