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 sol

Embodiment Construction

[0057] Compare Figure 4 and image 3 The fundamental difference is that the headphone button signal will output a stable effective level after shaking for a certain period of time (usually a few mS to more than ten mS). Usually, the effective level width of the normal headphone button operation is 100mS to several Hundreds of mS, while the waveform output by the voltage comparator is constantly changing during audio self-oscillation, and the effective level width is small. Due to the delay characteristic parameters of the mobile phone audio loop, the frequency range of audio oscillation is generally above tens of Hz, that is, the oscillation period is below tens of mS. Accordingly, by properly improving the earphone button signal detection and debounce, the normal earphone button operation signal and the false button signal caused by the audio self-excited oscillation can be identified, thereby preventing misoperation of the earphone button. Specific steps include:

Abstract

The invention relates to a method for avoiding button mistake operation on the mobile terminal earphone, and relative mobile terminal, which is characterized in that: when the mobile terminal detects the earphone button signal, processing button vibration-removal treatment; if said earphone button signal is effective after the button vibration-removal treatment, the mobile terminal detects the change of voltage of earphone button signal, in preset time; the mobile terminal according to the detected result processes relative earphone button operation. With said invention, the false earphone button signal caused by sound self-activated vibration in the inserting or drawing process can be recognized, to avoid the button mistake operation.

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...
