Volume adjustment device

Abstract

The invention relates to the technical field of electronic equipment, and discloses a volume adjustment device. The volume adjustment device comprises a protecting and supporting unit, a rotary adjustment unit and a detection control unit; a photoelectric sensing module is arranged in the protecting and supporting unit; the rotary adjustment unit is connected to the protecting and supporting unitin a rotatable manner; a signal shielding sheet is arranged on the rotary adjustment unit; the signal shielding sheet is used for shielding a photoelectric signal of the photoelectric sensing module;the detection control unit is electrically connected with the photoelectric sensing module; and the detection control unit is used for detecting a change of the photoelectric signal of the photoelectric sensing module and controlling the size of a volume output according to the change of the photoelectric signal. The volume adjustment device is easy and convenient to operate, low in part wear andstable and reliable in volume adjustment performance, improves the accuracy of volume adjustment, and can be designed into a large-diameter adjustment knob, which increases the comfortableness of a user during volume adjustment.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a volume adjusting device. Background technique [0002] The volume adjustment knob is an essential configuration in electronic products with sound. With the diversification of electronic products such as robots and smart speakers, the current volume adjustment knob on the market can no longer meet people's needs for new electronic equipment. The following problems: the rotary sliding type is a mechanical device with simple structure and low cost, which is in line with the operating habits of most people, but the sliding piece is easy to wear and cannot accurately adjust the volume; the digital button type needs to be pressed many times, which is inconvenient to operate and prone to failure . [0003] The volume adjustment knob is connected to the shaft of the potentiometer, and the volume is adjusted by turning the knob to drive the shaft of the potentiometer to ro...

[0002] The volume adjustment knob is an essential configuration in electronic products with sound. With the diversification of electronic products such as robots and smart speakers, the current volume adjustment knob on the market can no longer meet people's needs for new electronic equipment. The following problems: the rotary sliding type is a mechanical device with simple structure and low cost, which is in line with the operating habits of most people, but the sliding piece is easy to wear and cannot accurately adjust the volume; the digital button type needs to be pressed many times, which is inconvenient to operate and prone to failure

[0003] The volume adjustment knob is connected to the shaft of the potentiometer, and the volume is adjusted by turning the knob to drive the shaft of the potentiometer to rotate. However, due to the gap between the shaft of the potentiometer and the panel, the potentiometer will produce a small vibration when the device is playing. When turning the knob, the knob will deviate significantly, and the magnitude of this deviation will become larger as the diameter of the knob becomes larger. Therefore, the existing volume adjustment knob is smaller in size, and the volume adjustment knob with a small diameter is more laborious when turning, which affects User-adjustable volume comfort
