Problems solved by technology

[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, so it is easy to be affected by the surrounding environment and sneak into the 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. The soun

Embodiment Construction

[0018] The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings, but the present embodiments are not intended to limit the present invention, and any similar structures and similar changes of the present invention should be included in the protection scope of the present invention.

[0019] like Figure 1-Figure 2 As shown, the noise reduction pickup provided by the first embodiment of the present invention is characterized in that: it includes a contact microphone 11, an inner shell 12 and an outer shell 14; the outer shell 14 is closed at the top and open at the bottom, and its whole is bowl-shaped ; The inner shell 12 is housed in the outer shell 14, which is in the shape of a cuboid as a whole, and its bottom end surface protrudes outward from the opening at the bottom of the shell 14 to the outside of the opening (see figure 2 ), and the axial spacing h1 between the top inner wall of the outer casing...

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 ...
