Method for preventing mobile terminal earphone keystroke mis-operation and mobile terminal

Abstract

The invention discloses a method for preventing misoperation of earphone keys of a mobile terminal and a mobile terminal. The core of the method is: after the mobile terminal detects an earphone key signal, it performs key debounce processing; If it is still valid, the mobile terminal detects whether the earphone button signal level changes within a predetermined period of time; the mobile terminal performs corresponding earphone button operation processing according to the detection result. The technical scheme of the invention can identify the false earphone button signal generated by audio self-excited oscillation during the plugging and unplugging process of the earphone of the mobile terminal, thereby effectively preventing misoperation of the earphone button.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for preventing misoperation of buttons of an earphone of a mobile terminal and a mobile terminal. Background technique [0002] Most mobile phones are equipped with earphone accessories. In addition to having a receiver (i.e. an earphone) and a microphone (i.e. a microphone), the earphone accessory used in a mobile phone usually also has a button for answering / hanging up a call. The connection devices between earphone accessories and mobile phones are usually divided into two categories: one is connected through a special earphone plug / socket (or earphone jack), and the other is shared with the data I / O or charger of the mobile phone. An I / O connector. [0003] The connection between the earphone plug and the socket is generally 3-wire or 4-wire, one of which is used as a ground wire, one is a microphone, and the other one or two are earphones, so there a...

Problems solved by technology

[0020] Usually the button debounce delay is in the range of tens of mS to tens of mS. If the debounce delay is too large, the user will feel obvious slow response when pressing the button normally; mS level, so although the above-mentioned existing technical solution of reading back the button status with delayed software can effectively solve the problem of misoperation of the headset button caused by the button shaking, it cannot solve the problem of how to identify the problem caused by the self-excited oscillation of the audio during the plugging and unplugging of the headset. False headphone button signal, so as to prevent the problem of misoperation of the headphone button
