Abstract

The invention provides a non-contact audio equipment volume controller and a control method thereof. The non-contact audio equipment volume controller comprises: an electronic volume control chip, a front end circuit and a follow-up circuit. The non-contact audio equipment volume controller also comprises: a photoelectric sensor and control module possessing at least two infrared sensors; a single chip microcomputer, which is used to receive a photoelectric sensor and control module signal, determine an infrared signal sequence received by the at least two infrared sensors and output a control coding signal. Ports of outputting two channel control coding signals of the single chip microcomputer are respectively connected with a SDA port and a SCL port of the electronic volume control chip. During a regulation and control process, a user can only move one part of the body in a control scope of to the infrared sensors of the audio playback equipment to adjust the volume. Therefore, the user who is inconvenient to operate can use the audio playback equipment conveniently.

Description

[0001] Technology area [0002] The invention relates to a volume controller of an active non-contact audio playback device. Background technique [0003] Audio playback equipment is currently widely used in people's lives, and the output audio signal size needs to be controlled by the user's touch and adjustment of the audio controller on the device or through the buttons on the remote control (infrared or wireless remote control) Volume controls on the device. Such an adjustment method makes the user have to operate by hand during use, which brings inconvenience to the actual use of some special personnel. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a non-contact audio equipment volume controller and a control method thereof. [0005] The technical scheme adopted by the present invention to solve the above-mentioned technical problems is: a non-contact audio equipment volume controller, including an electro...
