Abstract

A high fidelity dual-audio player using a high fidelity mixer and a playing method thereof are disclosed, wherein the player comprises a microprocessor, a storage device, a recording device, a mixing and amplifying device and an output device. A decoding device and the storage device are both connected to the microprocessor. The recording device is connected to the storage device. The mixing and amplifying device is connected to the decoding device. The output device is connected to the mixing and amplifying device. The mixing and amplifying device comprises at least one first-stage amplification device, at least one second-stage amplification device and a mixing device. The player has the advantages of small volume (only the size as same as that of a mobile phone can be achieved) and HI-FI level of high fidelity; and in each of the two channels, left and right channels are enlarged respectively, so that the size as same as that of the mobile phone is achieved, and the signal to noise ratio, distortion and frequency response achieve high fidelity effect.

Description

technical field [0001] The invention relates to the technical field of electronic audio playback, in particular to a high-fidelity dual-audio playback device using a high-fidelity mixer and a playback method thereof. Background technique [0002] With the development of the electronic age, audio players, as an electronic product integrating entertainment and learning, have become a necessity in people's daily life. The flexibility and freedom of MP3 or MP4 players make it easier for us to listen to songs and enjoy the joy and charm that music brings to people. However, most of the existing audio players simply play the downloaded or recorded audio files; this playback mode cannot give the listener a multi-level experience, especially when listening to various learning audios, it seems boring and monotonous. Very tiring. [0003] The sampling rate of audio data is usually 44.1k, 48k or 96k, etc., and the decoding output of the playback device can usually only handle files w...
