A kind of energy consumption control method and wire control device

Abstract

The invention discloses an energy consumption control method and a wire control device. The wire control device includes a first button, a MIC module and a step-down module, and the step-down voltage of the step-down module is a second voltage. When the MIC module is in a non-use state and the first button is not pressed, the input voltage of the MIC module is the first bias voltage after passing through the step-down module. The difference between the set voltage and the second voltage, at this time, the current in the MIC module is the first current, and the method includes: when the MIC module is in the non-use state, detecting whether the first button is pressed to obtain a first detection result; when the first detection result indicates that the first button is pressed, the MIC module receives a second bias voltage as an input voltage, so that the current in the MIC module is the first Two currents, wherein the second current is different from the first current.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an energy consumption control method and a wire control device. Background technique [0002] With the advancement and development of science and technology, mobile phones are widely used in people's lives. Users can use mobile phones to talk, listen to music, and play games. [0003] Most of the mobile phones in the current market can control the mobile phone through the buttons on the earphones, such as: controlling the playback and stopping of music, the connection and hanging up of calls, etc. by the buttons on the earphones. The mobile phone detects the button on the headset by detecting the current on the MIC. The mobile phone will add a bias voltage to the MIC in the headset. Under normal circumstances, the button detection on the headset is carried out through the current on the MIC. For example: when the user is listening to music with earphones, for example, the mu...

AI Technical Summary

Problems solved by technology

[0007] The embodiment of the present application solves the problem of the headset in the prior art that the MIC module will always be in the power consumption state because there is always a bias voltage when the button is not pressed by providing an energy consumption control method and electronic equipment. Technical problem, realized the technical effect that the MIC module in the wire control device has no power consumption when the button is not pressed
