Problems solved by technology

[0002] Traditional AV power amplifiers or home theaters are mostly connected through speaker cables to drive speakers to produce sound. With the development of wireless technology, many products also realize audio transmission through wireless. The main working principle is to decode and convert different signal sources into PCM signals for use. Wireless transmission technology is used to realize wireless audio transmission. Traditional AV power amplifiers or home theaters usually have many and complicated connection lines, and the transmission in different spaces is relatively restrictive. Home theaters that use wireless technology reduce the trouble of physical wiring and realize equipment in different spaces. Any combination between them, but most of the current wireless product transmission is based on 2.4G, which is a widely used frequency band for wireless devices. If WIFI, Bluetooth and other devices are used at the same time, this frequency band will be very crowded and affect the connection quality and the transmission will reach less than hifi

Embodiment 1

[0021] Such as Figure 1 ~ Figure 3 As shown, the present invention provides a wireless micro-cinema system, including a wireless transmitter system for wirelessly transmitting audio signals after decoding and a wireless receiving system for receiving signals transmitted by the wireless transmitter system, the wireless transmitter system The device system includes VISAAV HUB system and WISADONGLE system two signal transmission systems;

[0022] Described VISAAV HUB system comprises HDMI transceiver module, receiver module, digital processing module, SUMMIT transmission module, bluetooth module, display unit module and transmission system control module, and described transmission system control module is connected with HDMI transceiver module, receiving Transmitter module, digital processing module, bluetooth module and display unit module, described digital processing module is connected with HDMI transceiver module, receiver module and SUMMIT transmission module respectively...

Embodiment 2

[0029] Such as Figure 4 As shown, the player is connected to the VISAAV HUB system through the HDMI input interface, and the projector is connected to the HDMI output interface. The VISA AV HUB system transmits the audio signal in the player wirelessly through the SUMMIT transmitter module, which is located in the PPA speaker. The receiving system receives the wireless signal transmitted by the VISAAVHUB system, and the power amplifier module of the wireless receiving system drives the speaker amplifier, so that people can experience it in the viewing area.

Embodiment 3

[0031] like Figure 5 As shown, the mixer in the bar is connected to the WISADONGLE system through the USB interface. The WISADONGLE system transmits and transmits the audio signal in the mixer wirelessly. The wireless receiving system located in the PPA speaker receives the wireless signal transmitted by the WISA DONGLE system. The power amplifier module of the wireless receiving system drives the loudspeaker amplifier.

Abstract

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.
