Tightly adjusted and controlled potentiometer

Abstract

The invention relates to the technical field of electronic components, and aims at solving the technical problem that when an electric brush of the potentiometer is adjusted, adjustment is inaccurate due to ineffective contact caused by long-term friction. A tightly adjusted and controlled potentiometer provided by the invention comprises a main potentiometer body, a controller and a motor, wherein the main potentiometer body comprises an insulating bottom plate, a rotating shaft, a semi-arc resistor body and an electric brush; the rotating shaft is arranged at the centre of the insulating bottom plate; the semi-arc resistor body rotates around the rotating shaft; the electric brush comprises an electric brush base, a connection part and a contact part; the electric brush base is connected with the rotating shaft; the contact part is connected with the electric brush base through the connection part; the semi-arc resistor body is embedded into a groove which is formed by the electric brush base, the connection part and the contact part; a fastener is arranged on the connection part, and is used for adjusting the distance between the contact part and the electric brush base; the controller comprises a voice sensor, a processor and a control circuit; the motor is connected with the rotating shaft; and the control circuit is connected with the motor, so that good contact of the electric brush and the resistor body can be guaranteed, so as to realize flexible adjustment and control.

Description

technical field [0001] The invention relates to the technical field of electronic components, in particular to a potentiometer for fastening adjustment control. Background technique [0002] In the prior art, when the potentiometer controls the output of the corresponding resistance value by adjusting the brush, because the brush often rubs against the resistor body, causing damage and making the contact ineffective, resulting in inaccurate technical problems in subsequent adjustments. Contents of the invention [0003] The embodiment of the present invention provides a potentiometer for tightening adjustment control, which solves the technical problem of inaccurate adjustment caused by long-term friction when adjusting the brush of the potentiometer in the prior art, and further realizes the Ensure the good contact between the brush and the resistor body, so as to flexibly adjust the technical effect of the control. [0004] In order to solve the above technical problems...
