SPEAKER, MODULE USING THE SAME, ELECTRONIC EQUIPMENT AND DEVICE, AND SPEAKER PRODUCING METHOD |
| 摘要 |
Edges (29) supporting a vibrating plate assembly (100) on a frame (26) are connected at their outer peripheral parts to the frame (26) and joined at their inner peripheral parts to a diaphragm (27) at a position more peripherally inward than is a voice coil (28). The edges (29) locally overlap the diaphragm (27). This arrangement makes it possible to reduce the dimensions of the speaker without reducing the dimensions of a permanent magnet (21) and the edges (29). |
