The invention discloses a wireless micro-cinema system comprising a wireless transmitter system which is used for decoding audio signals and then wirelessly transmitting the audio signals and a wireless receiving system which is used receiving the signals transmitted by the wireless transmitter system. The wireless transmitter system comprises two signal transmitting systems of a VISA AV HUB system and a WISA DONGLE system. Compared with the systems in the prior art, the wireless micro-cinema system has the characteristics of short distance communication, high real-time performance and high node capacity and can automatically jump frequency to avoid radar wave and other bands of which 5G is occupied; and the system has sufficient bandwidth and can transmit high-fidelity music of 24BIT, and the sound delay characteristic of lowing to 2.6 milliseconds is far better than that of other technical schemes so that the system is more suitable for the wireless communication requirement between sound equipment, stable in signal and abundant in function, the high-fidelity music can be enjoyed without modifying original decoration and the cinema system can be easily established.
