Abstract: The present disclosure is provided an audio processing device and an audio playback system thereof. The audio processing device includes a receiving module configured to receive an audio signal and identify a transmission mode of the audio signal, with the transmission mode at least including a Bluetooth transmission mode and a WIFI transmission mode; a processing module configured to decode the audio signal into an analog audio signal and a digital audio signal; an output module configured to receive the analog audio signal and the digital audio signal and then output the analog audio signal to a conventional audio via an AUX analog output port and output the digital audio signal to an HiFi audio via an optical fiber output port. The present disclosure can receive audio signals with different transmission types and output the audio signals of different types, which enriches audio selectivity and is of high interest.

Abstract: A vehicle-mounted charger having voice control function includes: a contact plug, a charging socket, a voice acquisition unit, a recognition control unit, and a first BLUETOOTH unit. The voice acquisition unit collects a voice signal and converts the voice signal to an electrical signal. The recognition control unit includes a conversion module, a first storage module, an operation module, and an executive module. The conversion module converts the electrical signal into a data signal and sends the data signal to the operation module. The operation module compares the data signal with predetermined storage data stored by the first storage module, operates the data signal, and sends control command to the executive module. The executive module sends executive command according to the control command. The first BLUETOOTH unit sends BLUETOOTH signal to the portable device according to the executive command to control the portable device to execute corresponding operation.
