[0005] Therefore, when the vibration plate 7 oscillates, unnecessary resonance is generated in the outer peripheral portion 7A to disturb the frequency characteristics, and in a severe case, quality defects such as generation of abnormal sound called surface squeal may occur. These phenomena often occur particularly when the weight of the diaphragm 7 is reduced in order to improve the sound pressure level.

As described above, the speaker according to the present invention has the following features.
Since the shape of the outer peripheral portion of the diaphragm is corrugated, the rigidity of the diaphragm with respect to the vertical amplitude is increased, and unnecessary resonance and surface squeal can be prevented. Therefore, it is possible to easily improve the sound pressure level by improving the input resistance of the speaker and reducing the weight of the diaphragm, and it is also possible to prevent poor quality such as abnormal sound due to surface squeal, and to improve the frequency characteristics and sound pressure. It is possible to provide a speaker having excellent characteristics, and its industrial value is very large.
