The utility model provides a two audio playback device of high -fidelity of ware are thoughtlessly put to use high -fidelity, wherein play device includes microprocessor, storage device, recording device, thoughtlessly puts device and output device. Decoding device and storage device all connect in microprocessor, recording device connect in storage device, thoughtlessly put the device connect in decoding device, output device connect in thoughtlessly put the device. It includes at least one one -level amplification device, at least one second grade amplification device and an audio mixing device thoughtlessly to put the device. The utility model discloses can HI the high -fidelity be accomplished moreover to small (possible only cell -phone size) the FI level, the utility model discloses an each sound channel in the dual track controls the sound channel to enlarge respectively to realize the volume of cell -phone size, SNR, the degree of distortion, frequency response all reach the effect of high -fidelity simultaneously.
