Abstract

The invention discloses a response key touch operating method which is applied to an MTK chip of an electronic device. A voltage processor is arranged in the electronic device and triggered when the output voltage of a line control earphone meets a first preset range so that the dormant state of the voltage processor can be converted into the work state. The voltage processor judges key touch operation of the line control earphone according to the output voltage of the line control earphone. The voltage processor is prevented from being triggered when the output voltage does not meet the first preset range so that the voltage processor can keep in the dormant state. Power consumption is reduced, and more electricity is saved by the electronic device. In addition, due to the fact that the MTK chip is an existing structure in the electronic device, no internal structure of the electronic device needs to be added, the structure change is small, and the achievement is easy.

Description

technical field [0001] The invention relates to the technical field of wire-controlled earphones, in particular to a method, device and electronic equipment for responding to button touch operations. Background technique [0002] Wire-controlled earphones refer to earphones that can control the access device through buttons on the earphone cable. For example, control the switch function of the remote MP3 device, play and stop function, volume adjustment function, etc. [0003] At present, the working principle of the wire-controlled earphone is as follows: resistors of different resistances are connected in parallel to the microphone of the wire-controlled earphone, a switch is connected in series with each resistor as a button, and a voltage processor is provided in the electronic device. When the wire-controlled earphone is plugged into the electronic device, the electronic device invokes the voltage processor to detect the output voltage of the wire-controlled earphone, ...
