Audio player with adjustable compensation frequency

Abstract

The invention discloses an audio player with adjustable compensation frequency. The audio player is mainly composed of a microprocessor control module, a filter module, an audio mixer module, an audio hardware decoding module, a power module I and a power module II, wherein the power module I and the power module II are respectively responsible for voltage transformation and voltage stabilization and supplying power to the microprocessor control module, the filter module, the audio mixer module and the audio hardware decoding module; the audio hardware decoding module is responsible for decoding, amplifying and outputting an audio compressed file; the filter module is responsible for filtering high frequency components of compensation digital audio; and the audio mixer module is responsible for mixing original audio with compensation audio, and the microprocessor control module is responsible for coordinating the audio hardware decoding module and adjusting the compensation frequency. The audio player disclosed by the invention adopts an MCU and a filter to control the output of the compensation frequency, and the original audio frequency and the compensation frequency are fused by an audio mixer. The MCU controls the generated compensation frequency, and the output of audio frequency with a specific effect is achieved.

Description

technical field [0001] The invention relates to a circuit device, in particular to a circuit device for audio playback. Background technique [0002] An audio player is a device that can decode, amplify, and finally process an audio signal into a signal acceptable to the human ear. At present, such electronic products are widely used in various fields of consumer electronics products, but the current audio players are mainly for ordinary people to listen to, and the final output sound wave frequency is low. Some people who are sensitive to high-frequency sound signals cannot produce enough pleasure. Most of the existing high-frequency audio signals on the Internet are single audio signals, and the audio segment cannot be adjusted. Contents of the invention [0003] In order to make up for the deficiencies of the existing technology and solve the problem that some people who are sensitive to high-frequency sound signals cannot produce enough pleasure, an audio player with ...
