The invention discloses an acoustic noise reduction device which comprises a mounting ring sleeving the outer side of a microphone handle, and further comprises an inner blocking cover sleeving the outer side of a microphone part, the outer side of the inner blocking cover is further sleeved with an outer blocking cover, and a cavity corresponding to the microphone part is formed in the upper portion of the inner blocking cover. A notch corresponding to the microphone portion and the cavity is formed in the upper portion of the outer blocking cover, the notch is larger than the cavity in size,and the mounting ring and the microphone handle are detachably installed through two fixing mechanisms. According to the scheme, the inner blocking cover and the outer blocking cover which are matched with each other are arranged at the head of the microphone, so that interference of external noise is avoided during use, the inner blocking cover and the outer blocking cover can always keep cavities and gaps of the inner blocking cover and the outer blocking cover aligned with a mouth, namely a sound source, of a user, normal receiving is guaranteed, and noise isolation is guaranteed; and after use is finished, anti-collision and dustproof processing can be carried out on the microphone head to ensure that the microphone head can normally receive a sound source.
Description
technical field [0001] The invention relates to the technical field of microphone noise reduction, in particular to an acoustic noise reduction device. Background technique [0002] Microphone, scientific name microphone, translated from English microphone (microphone), also known as microphone, microphone. Microphones are energy conversion devices that convert sound signals into electrical signals. There are moving coil, condenser, electret and recently emerging silicon micro microphones, as well as liquid microphones and laser microphones. Most microphones are electret condenser microphones, which work by utilizing a polymeric diaphragm with permanent charge isolation. [0003] In the prior art, when the microphone is in use, its microphone head will receive external noise except for the user's voice, which seriously affects its normal use. Therefore, we propose an acoustic noise reduction device. Contents of the invention [0004] The object of the present invention ...
