Problems solved by technology
The rapid development of multimedia technology makes karaoke, a traditional entertainment project, have a broader prospect. At present, the Android / smart karaoke system on the market, especially the home Android / smart karaoke system, needs an external USB receiver / USB wired connection / coaxial cable connection / separation cable connection, and all need to be mounted on the shell, resulting in poor aesthetics and mobility
Moreover, there is a sound output delay in the current karaoke system, and the human voice cannot be output in real time, so that the human voice output by the karaoke system is delayed for a long time compared with the vocal voice sung by the singer, and the human voice output by the karaoke system is relatively slow. The background music output by the karaoke system is delayed, that is, the human voice does not match the background music, so it cannot meet the needs of users, and the user experience is poor

The invention discloses digital audio-video equipment. The digital audio-video equipment comprises a housing, a projection module, a wireless audio receiving and decoding module, a wired audio receiving module, a channel switching module, a processing module, an amplifying module, a volume control module, a digital audio mixing module, and a digital audio output module. The wireless audio receiving and decoding module is arranged in the housing. After a to-be-processed audio signal output from the channel switching module passes across the amplifying module, the volume control module and the digital audio mixing module, the to-be-processed audio signal is directly mixed with a background music signal output from the processing module, so a mixed signal is formed. In this way, real-time outputs can be achieved.
Description
technical field [0001] The invention relates to a digital audio-visual equipment, in particular to a digital audio-visual equipment which can mix and output human voice and background music in real time. Background technique [0002] With the development of multimedia technology, more and more digital multimedia devices have entered people's work and life. The rapid development of multimedia technology makes karaoke, a traditional entertainment project, have a broader prospect. At present, the Android / smart karaoke system on the market, especially the home Android / smart karaoke system, needs an external USB receiver / USB wired connection / coaxial cable connection / separation cable connection, and all need to be mounted on the shell, resulting in poor aesthetics and mobility. Moreover, there is a sound output delay in the current karaoke system, and the human voice cannot be output in real time, so that the human voice output by the karaoke system is delayed for a long time co...
