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 comprises first and second microphones and a delay element. When sound is input to the first and second microphones, the delay element delays an output signal of the first microphone so as to detect the sound by a difference signal between the output signal of the first microphone and an output signal of the second microphone. The delay element delays the output signal of the first microphone so as to satisfy relation 0.76≦D/Δr≦2.0 where D is amount of delay for the output signal of the first microphone while Δr is distance between the first and second microphones. 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 comprises a microphone, leg members and a base. The microphone comprises a diaphragm for detecting sound and a housing for containing the diaphragm. The leg members project outwardly from a rear wall of the housing, and are provided near a second through-hole which connects a second inner space to outer space. The base is connected to the leg members to form a gap between the housing and the base. When the microphone unit thus formed in a simple structure and reduced thickness is mounted in a product, the gap allows the outer space to be connected to the second inner space through the second through-hole, making it possible to efficiently guide sound to the second inner space and obtain good differential characteristics.
