| Zusammenfassung: | The utility model provides a dual-mode digital audio system, comprising a master control module, a slave module, a Bluetooth module, an analog audio module, and a coding and decoding device, wherein the coding and decoding device is connected with the master control module through an analog signal channel and connected with the slave module through a digital signal channel, the master control module and the slave module are respectively connected with the Bluetooth module through the digital signal channel, and the analog audio module is connected with the master control module and the coding and decoding device through the analog signal channel respectively. The dual-mode digital audio system does not need specially-designed slave module and Bluetooth module, thereby reducing production difficulty and cost and increasing practicality and adaptility; and basically employs a digital signal channel, thereby enhancing the interference resistance of signals. |
