发明名称 Dynamic microphone
摘要 There is provided a dynamic microphone in which the output impedance does not increase and also the failure rate does not increase though using a microphone unit and a vibration detecting unit to reduce handling noise. In the dynamic microphone including a microphone unit 20 that includes a first diaphragm 24 and a first magnetic circuit 26 and delivers sound signals and a vibration detecting unit 30 that includes a second diaphragm 32 and a second magnetic circuit 33 and detects vibrations applied to a microphone case, whereby the output signal of the vibration detecting unit 30 being delivered as an opposite phase with respect to the output signal of the microphone unit 20, a field coil 41 excited by the output signal of the vibration detecting unit 30 is provided on the first magnetic circuit 26 side of the microphone unit 20.
