Earphone with automatic volume adjustment function and volume adjusting method

Abstract

The invention discloses an earphone with an automatic volume adjustment function, which comprises: an earphone main body and a sound outlet part, wherein the earphone main body comprises a front cavity MIC close to the sound outlet part so as to acquire an environment audio signal of the sound outlet part; a front cavity audio conversion circuit which is used for converting an environment audio signal acquired by the front cavity MIC to obtain a corresponding environment audio electric signal; a rear cavity MIC which is used for collecting an external real-time environment sound signal; a rearcavity audio conversion circuit which is used for converting an external real-time environment sound signal acquired by the rear cavity MIC to obtain a corresponding external real-time environment sound electric signal; and a processing control module which is used for analyzing and processing according to the environment audio electric signal and the external real-time environment sound electricsignal to obtain corresponding environment audio volume data and external real-time environment sound volume data, obtaining the required playing volume in combination with a pre-stored basic playingvolume data ratio, and adjusting and controlling the playing volume to be equal to the required playing volume. The invention further discloses a volume adjusting method for automatically adjusting the volume.

Description

technical field [0001] The invention relates to the technical field of intelligent terminal control, in particular to an earphone with an automatic volume adjustment function and a volume adjustment method.

However, since the volume emitted by the earphones is directly transmitted to the human ear, if the volume of the earphones is too high Seriously affect the comfort of the user, and may even endanger the hearing of the user; if the volume of the earphone is too low, the user will not be able to hear clearly, which will affect the user's use effect

[0003] At present, if the user wants to adjust the volume of the earphone, he usually needs to directly adjust the electronic device (such as a computer, mobile phone, etc.) connected to the earphone, or adjust the button on the earphone connection line, that is, most of the existing earphone volume adjustment methods are The user manually adjusts, but in many occasions, for example, when the user is driving or carrying heavy objects with both hands, manual adjustment cannot be performed because the hands cannot be freed, which seriously affects the user's use effect, and even endangers the hearing of the user's ears. healthy
