Acoustic-controlled potentiometer

Abstract

The invention discloses an acoustic-controlled potentiometer which comprises a controller and a potentiometer body, wherein the potentiometer body is a digital potentiometer body, the controller consists of a master controller, a sound sensing assembly and a motion driving assembly, wherein the input end of the master controller is connected with the output end of the sound sensing assembly, the output end of the master controller is connected with the motion driving assembly, the output end of the motion driving assembly is connected with the control end of the potentiometer body, a control application is arranged in the master controller and comprises a set range of the potentiometer body when the volume of sound is higher than a specific value, and a set range of the potentiometer when the volume of the sound is lower than the specific value, the master controller consists of a CPU (Central Processing Unit) and a control circuit of the CPU, the motion driving assembly consists of a motion controller and a control circuit of the motion controller, and the motion controller comprises a Q172CPU. Through the mode, the acoustic-controlled potentiometer has the characteristics of being capable of controlling output voltage and the on and off operation of the potentiometer through the sound, convenient to use and unique.

Description

Technical field [0001] The invention relates to the field of metal products, in particular to a voice-controlled potentiometer. Background technique [0002] The general potentiometer only has the function of manually adjusting the output voltage, and does not have the function of controlling the switch and output voltage of the potentiometer through voice control. In some special applications, for example, the sound can automatically adjust the volume to increase with the noise of the environment. At this time, ordinary potentiometers cannot play a role. Summary of the invention [0003] The main technical problem to be solved by the present invention is to provide a voice-controlled potentiometer. Through the combination of a sound sensing component and a motion drive component, the potentiometer can be adjusted and controlled by the volume of the sound. [0004] In order to solve the above technical problems, a technical solution adopted by the present invention is to provide a ...
