Headset socket and headset keypad detection method

Abstract

The embodiment of the invention discloses a headset base with an answering keypad function and a headset keypad detection method, which can avoid the phenomena of hanging up or answering the telephone by accident. The method in embodiment of the invention comprises the following steps: detect whether a pin of a left telephone receiver and / or a pin of a right telephone receiver of a headset male connector are in-place or not; when the pin of the left telephone receiver and the pin of the right telephone receiver are not in-place, directly determine that a headset keypad is not pressed down; when one of the pin of the left telephone receiver and the pin of the right telephone receiver is in-place, detect whether a microphone shrapnel (4) of the headset socket and an earth shrapnel (1) are short-connected by a pin of a microphone of the headset male connector, when the microphone shrapnel (4) of the headset socket and the earth shrapnel (1) are short-connected, determine that the headsetkeypad is pressed down, otherwise, determine that the headset keypad is not pressed down.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to an earphone base with an answer key function and an earphone key detection method. Background technique [0002] According to the standard definition of the 2.5mm / 3.5mm headphone jack, the headphone with the answer button function is to identify whether the button is pressed by shorting the microphone (MIC) on it to the ground. In the process of plugging and unplugging the male plug of the earphone, when the base of the male plug is about 2.3mm away from the female socket of the headset, the MIC pin of the male plug will short-circuit the shrapnel of the MIC of the female socket and the shrapnel of the female socket. Distinguished from normal key-press signals. [0003] In the process of realizing the present invention, the inventor has found that the prior art has at least the following problems: [0004] For earphones with the function of answer button, this kind of MI...

Problems solved by technology

[0004] For earphones with the function of answer button, this kind of MIC short circuit can be distinguished from normal buttons by software when the user quickly plugs in and out, but if the user slowly plugs in and out the earphone, the shrapnel of the MIC of the earphone female seat is short-circuited and grounded with the normal button MIC. If the short grounding time of the shrapnel is equal, it will generate a consistent signal with the normal button press, resulting in the phenomenon of hanging up or answering the phone by mistake, which will affect the user's experience
