Abstract

PURPOSE:To reduce a high cut peak, by securing a coincidence between the resonance frequency of a vacant chamber part provided in front of an edge and the frequency that causes a high cut peak due to the divided vibrations of a diaphragm. CONSTITUTION:A gasket 34 is extended to obtain a coincidence between the resonance frequency fe of a vacant chamber part 36 provided in front of an edge 16 and the frequency fh that causes a high cut peak due to the divided vibrations of a diaphragm 10. Thus the valley of frequency fe and the peak of frequency fh are nagated to each other to ensure a flat high frequency region for the sound pressure characteristics. In such way, the high cut peak can be reduced.
