Problems solved by technology

The area of ​​the microphone corresponding to the sound hole is usually equipped with a mesh cloth for dustproof and windproof, but the thickness of the mesh cloth in the current microphone device is relatively thin, which is easy to block the sound hole, resulting in poor sound
The usual solution is to form a front cavity between the inner surface of the shell and the microphone, and the setting of the front cavity will form resonance, resulting in a decrease in the high-frequency performance of the product

Embodiment Construction

[0047] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0048] figure 1 The microphone device in the prior art is shown. The microphone device includes a housing 11 and a microphone 12 accommodated in the housing. The housing 11 is provided with a sound hole 111 corresponding to the microphone 12. The sound hole 111 ensures that sound can enter microphone12. The microphone 12 is further provided with a mesh cloth 13 for dustproof or windproof. In this microphone device, since the mesh cloth 13 is relatively thin, it is easy to block the sound hole 111 during use. Therefore, ...

Abstract

The invention discloses a microphone device, including a housing and a microphone contained in the housing, wherein the housing is provided with a sound hole corresponding to the microphone, an innersurface of the housing corresponding to the sound hole recesses to form a groove, a damping member is disposed between the inner surface of the housing and the microphone, and the damping member covers the groove. The microphone device further includes a filter converter electrically connected to the microphone. The filter converter performs low frequency filtering on the output signals of the microphone. The invention also discloses an earphone including the microphone device. The invention is capable of adjusting the frequency response curve of the microphone device to improve the acoustic performance of the acoustic products.

Description

technical field [0001] The invention relates to the technical field of acoustic-electric conversion. More specifically, it relates to a microphone device and an earphone including the microphone device. Background technique [0002] Most of the current acoustic products are equipped with a microphone device. The microphone is the basic acoustic-electric conversion unit, which can convert the sound air flow into an acoustic current signal for processing and transmission. The microphone device includes a housing and a microphone housed in the housing. The housing is usually provided with a sound hole corresponding to the microphone for the external airflow to enter the microphone through the sound hole. The area of ​​the microphone corresponding to the sound hole is usually provided with a dust-proof and windproof mesh, but the thickness of the mesh in the current microphone device is relatively thin, which is easy to block the sound hole, resulting in poor sound production. ...
