Abstract:
A microphone unit (1) comprises a first vibrating part (14), a second vibrating part (15), and a housing (20) for accommodating the first vibrating part (14) and the second vibrating part (15), the housing being provided with a first sound hole (132), a second sound hole (101), and a third sound hole (133). The housing (20) is provided with a first sound path (41) for transmitting sound pressure inputted from the first sound hole (132) to one surface (142a) of a first diaphragm (142) and to one surface (152a) of a second diaphragm (152), a second sound path (42) for transmitting sound pressure inputted from the second sound hole (101) to the other surface (142b) of the first diaphragm (142), and a third sound path (43) for transmitting sound pressure inputted from the third sound hole (133) to the other surface (152b) of the second diaphragm (152).
