Abstract

The invention relates to a unidirectional microphone, which comprises a microphone unit, an inner housing, an outer housing located on the outer peripheral side of the inner housing, and an end cover, the inner housing is formed with a cavity, and the cavity is separated into a front cavity by the microphone unit Body and rear cavity, the end cover part extends into the front cavity, and is set at one end of the inner shell and the outer shell to block the front cavity, and a front sound hole connecting the outside air and the front cavity is opened on the unidirectional microphone And the front sound leak hole, and also open the rear sound inlet hole and the rear sound leak hole that communicate with the outside air and the rear cavity. The invention is used to solve the problem of poor unidirectional performance of the unidirectional microphone in the prior art.

Description

technical field [0001] The invention belongs to the technical field of microphones, and in particular relates to a unidirectional microphone. Background technique [0002] The directivity of the microphone refers to the fact that the microphone picks up sound from different directions. It is generally divided into omnidirectional and unidirectional. ;Unidirectionality is the deepest non-response zone according to its opposite direction of 180 degrees, so the sound signal from the back of the sound head will be the least picked up, and the sound pickup effect is the best when it is facing the microphone at 0 degrees. [0003] Operators are often equipped with special earphones, and the surrounding environment of the operator is mostly noisy, and the microphone in the earphone is unidirectional, such as figure 1 , which shows some structural components of the existing unidirectional microphone, which belongs to the differential pressure type, such as figure 1 As shown, it ma...
