手机降噪装置

Noise reduction device of mobile phone

Abstract

本实用新型公开了一种手机降噪装置,其包括一手机降噪单元、一单刀双掷开关及一噪声采集模块,其中,该手机降噪单元与该单刀双掷开关电连接,该单刀双掷开关与该噪声采集模块电连接,该噪声采集模块为一手机耳机及一手机扬声器;该手机降噪单元还与一手机基带芯片电连接,通过该单刀双掷开关的切换,该手机耳机及手机扬声器分别与该手机基带芯片、该手机降噪单元形成两路降噪控制回路。采用本实用新型,可以不需要另外安装MIC(麦克风)即可实现手机降噪。
The utility model discloses a noise reduction device of a mobile phone, comprising a mobile phone noise-reduction unit, a single-pole double-throw switch and a noise sampling module, wherein the mobile phone noise-reduction unit is electrically connected with the single-pole double-throw switch which is electrically connected with a noise collection module, and the noise collection module is an earphone of the mobile phone and a loudspeaker of the mobile phone; the mobile phone noise-reduction unit is also electrically connected with a baseband chip of the mobile phone, the earphone of the mobile phone and the loudspeaker of the mobile phone respectively form two circuit noise-reduction control loops with the baseband chip of the mobile phone and the mobile phone noise-reduction unit by the switching of the single-pole double-throw switch. By adopting the utility model, an MIC does not need to be additionally arranged to realize noise reduction of the mobile phone.
