    摘要: A microphone unit comprises a vibratory diaphragm for detecting sound input through its first and second openings. The sound input through the first opening is guided to a front surface of the vibratory diaphragm while the sound input through the second opening is guided to a rear surface of the vibratory diaphragm so as to detect the sound by the vibration of the vibratory diaphragm. The microphone unit satisfies relation 0.76≦D/Δr≦2.0 where D is difference in time between the sound propagation time from the first opening to the front surface of the vibratory diaphragm and that from the second opening to the rear surface of the vibratory diaphragm, while Δr is distance between the first and second openings. The relation D/Δr≦2.0 can reduce far-field noise, while the relation 0.76≦D/Δr can increase the detection sensitivity to sound emitted from a null point.

    摘要: A microphone unit includes a case; a diaphragm arranged inside the case; and an electric circuit unit that processes an electric signal generated in accordance with vibration of the diaphragm. The case has a first sound introducing space that introduces a sound from outside of the case to a first surface of the diaphragm via a first sound hole; and a second sound introducing space that introduces a sound from outside of the case to a second diaphragm, via a second sound hole. A resonance frequency of the diaphragm is set in the range of ±4 kHz based on the resonance frequency of at least one of the first sound introducing space and the second sound introducing space.

    摘要: A microphone unit (2) includes: a microphone substrate (13); and a partition unit (20) having a diaphragm (22). The microphone substrate (13) has a first substrate opening (14) and a second substrate opening (15). The partition unit (20) covers the first substrate opening (14) and the diaphragm (22) covers a part of the first substrate opening (14) so as to form an internal space containing an in-substrate unit space (12) formed at least in the microphone substrate (13) and communicating with outside from the diaphragm (22) via the first substrate opening (14) and the second substrate opening (15). This realizes a microphone unit in which a differential microphone configured by a single diaphragm is mounted with a high density.
