Noise reduction pickup

Abstract

A noise reduction pickup relates to the technical field of pickup technique, solving the technical problem of reducing background noise. The pickup is characterized by comprising a contact microphone, an inner shell and an outer shell. The outer shell is provided with a closed top and an opened bottom, and is in a bowl-shaped whole structure. The inner shell is arranged in the outer shell, the end surface of the inner shell protrudes from the opening at the bottom of the outer shell to the outside of the opening, and the axial distance between the inner wall of the top of the outer shell and the end surface of the top of the inner shell is larger than the axial distance between the bottom border of the outer shell and the end surface of the bottom of the inner shell. The side of the inner shell is provided with at least two flexible cantilevers in axial symmetry, and the flexible cantilevers are connected with the outer shell. The contact microphone is arranged in the inner shell. The noise reduction pickup of the invention can effectively reduce the background noise.

Description

technical field [0001] The invention relates to the technology of a sound pickup, in particular to a technology of a noise reduction pickup capable of effectively reducing background noise. Background technique [0002] The current pickups are divided into the following two types according to the sound pickup method: one is an ordinary microphone, which picks up sound waves directly to pick up sound, so it is easy to be affected by the surrounding environment and sneak into noise; the other is a contact microphone, a contact microphone. When the microphone is used, it must be in close contact with the skin of the human body, and the sound is picked up by absorbing the vibration generated by the skin when the human body makes a sound. Although the contact microphone can filter out most of the noise in the surrounding environment, because the parts that make the contact microphone closely contact the human skin will The ambient air vibration is absorbed and transmitted to the ...

Although the contact microphone can filter out most of the noise in the surrounding environment, the parts that make the contact microphone closely contact the human skin will Absorbs ambient air vibrations and transmits them to the contact microphone, so the background noise of the contact microphone is still high
