Patent ID: 8804983

Claim:
A microphone comprising: a first microphone unit comprising a diaphragm, a fixed electrode and a FET as an impedance converter; a first plug outputting audio signals output from the first microphone unit; and a jack into which audio signals inputted in the first microphone unit are inputted, wherein the microphone is connectable to a subsequent microphone that is different from the microphone, wherein one of the diaphragm and the fixed electrode is comprised of an electret member, wherein the jack is connectable to a second plug of the subsequent microphone, the second plug includes a signal output terminal, wherein, while the second plug of the subsequent microphone is inserted in the jack of the microphone, the signal output terminal of the subsequent microphone is directly connected to the diaphragm of the microphone, audio signals output from a second microphone unit of the subsequent microphone are added to the audio signals output from the first microphone unit and are output.
