An electronic device and its control system for automatically reducing the power consumption of the vibrator

Abstract

The invention relates to a control system for automatically reducing oscillator power consumption. The control system comprises a signal processing module, a signal detecting circuit, a power supply module and an oscillator driving circuit. The signal detecting circuit detects input signals, outputs control signals to the power supply module, and controls the power supply module to supply power to the oscillator driving circuit or not. When audio signals are input, the signal detecting circuit outputs the control signals to the power supply module, the power supply module is controlled to supply the power to the oscillator driving circuit, and the oscillator driving circuit drives an oscillator to work. When no signal is input, the signal detecting circuit outputs the control signals to the power supply module, the power supply module is controlled not to supply the power to the oscillator driving circuit, and the oscillator driving circuit stops outputting the driving signal so as to achieve the aim of saving electric energy. Therefore, the control system can control to supply the power to the oscillator driving circuit or not according to whether the audio signals are input or not, the situation that when no audio signal is input, the oscillator generates a large amount of power consumption can be avoided, the electric energy is saved, and the service life of the electronic equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of power consumption control of electronic equipment, in particular to a control system for automatically reducing power consumption of a vibrator and electronic equipment using the control system. Background technique [0002] At present, in order to improve user experience, electronic devices are generally equipped with a vibrator. When the received audio signal contains vibration information, the vibrator vibrates to simulate environmental vibration and bring more realistic feelings to users. [0003] When an existing electronic device receives an audio signal, the signal processing module analyzes and outputs the vibrator drive signal, and the vibrator drive circuit amplifies the vibrator drive signal and outputs it to the vibrator to drive the vibrator to vibrate. However, when the electronic device does not receive an audio signal, the vibrator driving circuit will output a driving signal with a fixed ...
