Problems solved by technology
This technical solution cannot be connected to two USB hosts at the same time, so that the digital audio signals of the two USB hosts can communicate with each other or the technical solution from the USB interface to the optical fiber coaxial interface
[0004] None of the above-mentioned technical solutions can achieve simultaneous access to two USB hosts and realize full digital signal transfer, and cannot completely overcome the above-mentioned shortcomings. Therefore, we propose a digital audio signal connector and an audio signal conversion method to solve the above-mentioned problems

The invention discloses a digital audio signal connector and an audio signal conversion method, and relates to the technical field of digital audio, two USB (Universal Serial Bus) interfaces are adopted to enable two USB hosts to transmit digital audio signals mutually, and compared with the existing equipment, the digital audio signal connector has the advantages that the USB interfaces are used for receiving the digital signals of the USB hosts, and the digital audio signal conversion method is convenient to use. The connector is characterized in that through the internal circuit board, the connector can receive a digital audio signal output by a USB host through one USB interface, the digital audio signal is transferred through an internal circuit and is transmitted to another USB host through another USB interface in a digital signal mode, and meanwhile reverse transmission can be achieved. Finally, the digital audio signals of the two USB hosts are communicated without digital-to-analog conversion.
Description
technical field [0001] The invention relates to the technical field of digital audio, in particular to a digital audio signal connector and an audio signal conversion method. Background technique [0002] With the rise of the Internet live broadcast industry, many practitioners need to transmit digital audio with better sound quality on the Internet in real time. More and more people use professional sound card equipment. Most of the existing professional sound cards only provide a USB digital interface. Connected to the computer, the sound card device transmits audio to the computer, and then it is processed by the software and then transmitted to the sound card device. The sound card converts the received audio into an analog signal using a digital-to-analog conversion module, and finally connects to the mobile phone through an analog interface. The audio signal generated by the mobile phone playing audio or live broadcasting also needs to be converted to a sound card in t...
