Abstract

The invention discloses a driving circuit of earphones and heart rate earphones. The driving circuit of the earphones comprises a power module, a heart rate detection module, a voltage acquisition module, a control module and a power amplifier module, wherein the heart rate detection module detects a heart rate; the voltage acquisition module detects a voltage value of the power module; when the heart rate detection module works, and the voltage value, detected by the voltage acquisition module, of the power module is less than or equal to a preset voltage value, the control module outputs a turning down control signal; and the power amplifier module adjusts an output volume according to a volume control signal. The driving circuit of the earphones solves the problem of inaccurate test data of the heart rate of the heart rate earphones in the prior art.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to a driving circuit of an earphone and a heart rate earphone. Background technique [0002] At present, with people's emphasis on sports and the development of wearables, many earphone manufacturers have begun to develop their own heart rate earphones, so there are more and more heart rate earphones. The heart rate headset mainly includes: Bluetooth module, audio input and output module, button module, storage module, power module, heart rate module. Due to the increase of the heart rate module, the power consumption of the entire headset increases, which in turn reduces the battery life of the headset. At the same time, since the heart rate detection module accounts for a large proportion of the total power consumption in the whole earphone, there are also certain requirements for the amplitude and accuracy of the voltage. [0003] When the user is running with a Bluetoo...
