Earphone circuit, earphone control method, and using method of earphone

Abstract

The invention provides an earphone circuit, an earphone control method, and a using method of an earphone. A state detection module is added and is used for detecting an attitude and a using state of an earphone and feeding back the attitude information to a control module; the control module determines the attitude of the earphone; and after analysis processing of the control module, other modules of the earphone are controlled, so that an objective of corresponding adjustment of the earphone can be achieved. And then the information is uploaded to a host.

Description

technical field [0001] The invention relates to the field of earphone manufacturing, in particular to an earphone circuit, a method for controlling the earphone and a method for using the earphone. Background technique [0002] Electronic devices (both mobile and fixed) are used in a wide range of applications, such as PCs, tablets, mobile phones, MP3 and MP4. As an indispensable external device in electronic equipment, external earphones and microphones (commonly known as headsets, or earphones with microphones) are traditionally used to output and drive audio signals from audio codecs inside mobile or fixed electronic equipment into In the earphone of the headset, the sound or music is generated and transmitted to the two ears. At the same time, it can transmit the audio electrical signal converted by the microphone on the headset to the audio codec inside the electronic device for further processing, thereby realizing two-way or one-way audio. Function. Although the com...

Problems solved by technology

Although the complexity of electronic equipment is getting higher and higher, and the replacement is faster and faster, the needs of users for headsets have not changed much for many years, and this trend will continue

[0003] However, due to the openness of the audio interface, more and more functions can be realized on the audio interface, but the problem is that the audio interface can only provide limited power supply capacity, and it cannot be well combined with the headphone function.
