Problems solved by technology
[0002] In the prior art, the loudspeaker generally uses an external knob to adjust the internal sliding resistance to adjust the output volume. This way of adjusting the volume of the loudspeaker is not accurate enough, and it cannot be memorized. The volume commonly used by people cannot be memorized, which affects people. The auditory effect, the volume of the scene cannot be set according to the scene of use, the effect of the scene used is not good enough

The invention discloses a loudspeaker based on a digital potentiometer. The loudspeaker comprises an audio input module, a pre-amplifier module, a digital potentiometer module, a power amplifier module, a loudspeaker module, a single-chip microcomputer module and a volume button module. The audio input module, the pre-amplifier module, the digital potentiometer module, the power amplifier module and the loudspeaker module are connected in sequence; and the volume button module is connected with the digital potentiometer module through the single-chip microcomputer module. According to the application, the single-chip microcomputer outputs an instruction for adjusting the resistance value of the resistor, the digital potentiometer is controlled to adjust the resistance value of the resistor in the loudspeaker, accurate regulation and control of the output volume of the loudspeaker are realized, and the single-chip microcomputer module can set different instructions for adjusting the resistance value of the resistor according to different application scenes, so the loudspeaker can directly output corresponding volumes in different application scenes, so that the volume control of the loudspeaker is more accurate, the application scenes are richer, and the loudspeaker can be used in various occasions and scenes.
Description
technical field [0001] The present disclosure generally relates to the technical field of potentiometers, in particular to a digital potentiometer-based loudspeaker. Background technique [0002] In the prior art, the loudspeaker generally uses an external knob to adjust the internal sliding resistance to adjust the output volume. This method is not accurate enough to adjust the volume of the loudspeaker, and it cannot be memorized. The volume commonly used by people cannot be memorized, which affects people. It is not possible to set the volume of the scene according to the scene of use, and the effect of the scene used is not good enough. [0003] Therefore, it is desired to have a digital potentiometer-based loudspeaker to solve the problems in the prior art. Contents of the invention [0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a digital potentiometer-based loudspeaker that can meet the multi-scenario appli...
