Abstract
PURPOSE:To cancel an oscillation noise component and to reduce an oscillation noise by arranging first and second microphone units so that respective diaphragms can be confronted with each other adjacently on the same axis, and taking out the sum signal of the output of the first and second microphone units as an output signal. CONSTITUTION:The diaphragms 9 and 10 of the microphone units 1 and 2 are arranged so as to be confronted with each other adjacently. Those microphone units 1 and 2 are fixed with a coupler 5. Thereby, the diaphragms 9 and 10 are oscillated in the same direction by exciting the whole of the microphone. Since the microphone units 1 and 2 are confronted with each other, the output of the microphone units 1 and 2 generated by the oscillation are set at opposie phases with each other. Therefore, by adding the output of the microphone units 1 and 2, it is possible to cancel the oscillation noise component.
