Problems solved by technology

[0002] At present, the basic functions of the audio system are signal transmission and control (amplification). However, due to the poor sound of the ceiling speakers in the traditional audio system, uneven sound levels, and equipment failures from time to time, it is very troublesome to frequently readjust the speaker position. Pipeline engineering is difficult to cooperate with decoration, and the use of professional audio equipment is too complicated, and the operator does not know what kind of music materials are suitable for selection. The equipment is expensive, the equipment system is complicated, and it is prone to failure, which brings many inconvenient

Embodiment Construction

[0022] Such as figure 1 As shown, after the audio controller (1) mixes the stereo sound source and the voice level of the microphone, it is sent to the network adapter (2) in the form of analog signal transmission. After the A / D conversion is performed by the network adapter, the TCP / IP communication protocol is compiled for the digital level signal, and the compiled Packet is broadcast to the entire LAN (3) via the network connection line.

[0023] The network wireless terminal (4) is in a standby state when no connection is established with the network adapter (2), which is similar to the standby state of a household television. When receiving the Packet sent from the network adapter (2) to the LAN (3), the network wireless terminal (4) will turn on the power of the power amplifier and enter into a normal communication working state. Through the built-in TCP / IP communication protocol, the received "packet containing lossless audio" is reinterpreted into a lossless digital a...

Abstract

The invention discloses a three-in-one audio transmission control system, mainly comprising an audio set controller, a network adapter, a network wireless terminal, an audio set and a wireless host. The three-in-one audio transmission control system is characterized in that a stereo sound source and microphone speech level are mixed and transmitted by the audio set controller to the network adapter in the transmission mode of an analog signal, the network adapter carries out A/D(Analog to Digital) conversion on the analog signal, a digital level signal is subjected to TCP/IP (transport control protocol/internet protocol) communication protocol compiling, and a compiled Packet is broadcasted to a whole LAN (local area network) through a network connecting wire. According to the three-in-one audio set transmission control system, a digital network technology, a radio technology, and a professional audio set and public broadcasting technology are unprecedentedly integrated, and all demands of users on the audio set are solved to the maximum extent.

Description

technical field [0001] The present invention relates to the field of audio system transmission control, in particular to an organic fusion of traditional analog audio technology, digital network audio technology and digital wireless audio technology, and parallelize three kinds of signals and standard channels in the same audio system operation, and finally build a new three-in-one audio transmission control system. Background technique [0002] At present, the basic functions of the audio system are signal transmission and control (amplification), but because the sound of the ceiling speakers of the traditional audio system is too poor, the sound is uneven, and the equipment fails from time to time, the position of the speaker needs to be readjusted frequently, which is very troublesome. Pipeline engineering is difficult to cooperate with decoration, and the use of professional audio equipment is too complicated, and the operators do not know what kind of music materials to...
