Problems solved by technology

[0002] In the current amplifier, the reverberation, reverberation delay and reverberation repetition functions in the sound effect control function are controlled by three parts of the circuit and three potentiometers respectively. The circuit is complex, the manufacturing cost is high, and because it is a fixed circuit Design, not easy to function upgrade or change
At the same time, the current loudspeaker has no display screen, so it is impossible to visually see the level of sound effect adjustment

Abstract

The invention discloses a functionally-diversified audio power amplifier circuit applying a rotary encoder. The circuit comprises a main control chip and a rotary encoder, wherein the rotary encoder is connected with the main control chip, and the main control chip is also connected with a display screen for displaying change levels. Through the cooperation of the main control chip and the rotaryencoder, the reverberation, reverberation delay and reverberation repeat functions of an audio power amplifier can be realized, complex circuits are not required, the manufacturing cost can be saved,and only one rotary encoder is adopted, the operation is simple, and the function upgrades or changes can be implemented; and meanwhile, the display screen is arranged, and thus the sound effect adjustment state can be intuitively viewed.

Description

technical field [0001] The invention relates to the field of loudspeakers, in particular to a multifunctional loudspeaker circuit using a rotary encoder. Background technique [0002] In the current amplifier, the reverberation, reverberation delay and reverberation repetition functions in the sound effect control function are controlled by three parts of the circuit and three potentiometers respectively. The circuit is complex, the manufacturing cost is high, and because it is a fixed circuit Design, not easy to function upgrade or change. At the same time, the current loudspeaker has no display screen, so it is impossible to visually see the level of sound effect adjustment. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a multi-functional loudspeaker circuit using a rotary encoder, which uses the cooperation of the main control chip and the rotary encoder to realize the functions of reverberati...
