Embodiment Construction

[0032] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples, so that the realization process of how to use technical means to solve technical problems and achieve technical effects in the present invention can be fully understood and implemented accordingly.

[0033] The core of the present invention: on the basis of maintaining the existing four-section plug-in earphone structure, by changing the mic circuit, the current of the earphone passes through different circuits to generate different current characteristic values ​​(or other electrical characteristic values) when the earphone is in different insertion states , so as to set the corresponding threshold according to these characteristic values ​​to detect the normal insertion of the earphone and the state of the mic button.

[0034] The method of the present invention is described below with an embodiment.

[0035] Such as Figure 4 As shown, a resis...

Abstract

The invention relates to a microphone (mic) key-press earphone and a state identification method. The state identification method comprises the steps that: by changing a mic circuit and a mic key-press circuit at the plug end of the earphone, the earphone forms different mic circuits in different inserting states, and the corresponding mic circuits generate different electrical characteristics, thereby setting the corresponding threshold values to detect the normal inserting state and the mic key-press state of the earphone according to the electrical characteristics. The invention utilizes the multi-current detection method and the device to replace the original method in which a left acoustic channel and the mic key-press are respectively detected, not only fundamentally overcomes the defects caused by the original two short circuits, but also combines the original two-way detection into one-way detection so as to save more devices and PCB (printed circuit board) spaces.

Description

technical field [0001] The invention relates to a microphone button earphone and a state recognition method, in particular to a four-segment mobile communication terminal earphone with mic (microphone microphone) button insertion and a method for identifying the mic button and the earphone with the recognition function. Background technique [0002] At present, the four-segment jack earphones commonly used in mobile communication terminal products mostly have the following problems: 1) when the earphones are not fully inserted, they are mistakenly thought that the earphones have been inserted, and there is no sound output from the mobile phone or howling from the earphones; In the state of a call or an incoming call, plugging / unplugging the headset slowly will cause the call to hang up or the call will be connected automatically. These errors greatly affect the user experience, reduce the quality of the product, and damage the brand reputation. [0003] By carefully studyin...
