Audio processing device and audio playback system thereof
View Patent ↗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.
1. An audio processing device comprising:
a receiving module configured to receive an audio signal and identify a transmission mode of the audio signal, the transmission mode at least comprising 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 output via an AUX analog output port and output the digital audio signal to an HiFi audio output via an optical fiber output port;
wherein the audio processing device further comprises a control circuit connected to the receiving module, the control circuit comprises a channel switch and an indicator light to connect different transmission modes for transmitting the audio signal, one or more signal transmission channels with the different transmission modes are controlled to be in a transmission state by the channel switch and the indicator light being in the transmission state is controlled to emit light.
2. The audio processing device as claimed in claim 1 , wherein the receiving module is configured to identify whether the transmission mode of the audio signal is the Bluetooth transmission mode or the WIFI transmission mode via an identification code carried by the audio signal, when the receiving module receives the audio signal.
3. The audio processing device as claimed in claim 2 , wherein during identifying the identification code carried, by the audio signal, when the identification code is 0, the audio signal is identified to transmit by the Bluetooth transmission mode and the channel switch corresponding to the Bluetooth transmission mode is controlled to open and light a corresponding indicator light, while when the identification code is 1, the audio signal is identified to transmit by the WIFI transmission mode and the channel switch corresponding to the WIFI transmission mode is controlled to open and light a corresponding indicator light.
