Abstract
The invention discloses a kind of movie theatre Wireless surrounding audio amplifier, including sound source, sound source power circuit, PA-system and PA-system power circuit, sound source includes audio input interface, audio processing modules, wireless transmitter module, PA-system includes wireless receiving module, power amplifier, speaker system, by above-mentioned radio connection, the wiring link during movie theatre is built can be exempted, the substitute is only to be required to be and only often be around audio amplifier laying mains supply, power-supply wiring is not required to connect up by surround speaker quantity, only need to lay one, construction cost is effectively controlled.
Description
Technical field
The present invention relates to a kind of sound equipment, particularly to a kind of movie theatre private radio surround speaker.
Background technology
Currently known movie theatre surround speaker system is made up of passive passive sound box and power amplifier, and passive loudspeaker box lifts
In movie theater on the design attitude of sound channel, power amplifier is placed in special projection booth, and the two is by the sound laid in advance
Frequently power line links together, in place of this known technology exists following imperfection:
1. wiring needs high-quality special-purpose audio line, and the lifting of fire-fighting wire casing is artificial in addition waits high cost, and client is difficult to connect
It is subject to.
2. distant between audio amplifier and power amplifier, wiring distance is longer, causes wire rod impedance higher, affects playback
Efficiency；
3. for the panorama sound shadow Room, the most tens of up to a hundred surround speakers, wiring installation is extremely complex, therefore design difficulty
The highest with construction cost, it is unfavorable for cost control；
Summary of the invention
It is an object of the invention to provide a kind of movie theatre Wireless surrounding audio amplifier, to solve at least in above-mentioned technical problem
Individual or whole.
According to an aspect of the invention, it is provided a kind of movie theatre Wireless surrounding audio amplifier, including sound source, source of sound dress
Putting power circuit, PA-system and PA-system power circuit, sound source includes audio input interface, audio processing modules,
Wireless transmitter module, audio input interface receives the audio signal of outside input, and the audio signal of input is sent at audio frequency
Reason module, audio processing modules receives the audio signal sent here of audio input interface and is processed as wireless transmitter module and can identify
Signal, be simultaneously transferred to wireless transmitter module, wireless transmitter module receive audio signal that audio processing modules sends here and with
Carrier system launches radio signal, and PA-system includes wireless receiving module, power amplifier, speaker system, wireless connects
Receiving after module receives the wireless carrier Audio Signal Processing that sound source is launched and send into power amplifier, power amplifier receives nothing
Audio signal that line receiver module is sent here is also transferred to speaker system after amplifying this signal, and speaker system receives power amplification
Audio signal that device is brought also is converted into acoustical signal, and sound source power circuit provides power supply, sound for sound source
Ring installation's power source circuit and provide power supply for PA-system.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the present invention a kind of movie theatre Wireless surrounding audio amplifier；
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in more detail.
Fig. 1 show schematically show the structure of a kind of movie theatre Wireless surrounding audio amplifier of one embodiment of the present invention.
As it is shown in figure 1, a kind of movie theatre Wireless surrounding audio amplifier, including sound source (1), sound source power circuit (2),
PA-system (3) and PA-system power circuit (4),
As it is shown in figure 1, sound source (1) includes audio input interface (11), audio processing modules (12), wireless transmit mould
Block (13), audio input interface (11) receives the audio signal of outside input, and the audio signal of input is sent into Audio Processing
Module (12), audio processing modules (12) receives audio input interface (11) audio signal sent here and is processed as wireless transmit mould
The signal that block (13) can identify, is simultaneously transferred to wireless transmitter module (13), and wireless transmitter module (13) receives Audio Processing
Audio signal that module (12) is sent here also launches radio signal with carrier system, and PA-system (3) includes wireless receiving module
(31), power amplifier (32), speaker system (33), wireless receiving module (31) receive sound source (1) launch wireless
Sending into power amplifier (32) after carrier frequency signal processing, power amplifier (32) receives what wireless receiving module (31) was sent here
Audio signal is also transferred to speaker system (33) after amplifying this signal, and speaker system (33) receives power amplifier (32) and send
The audio signal that comes over also is converted into acoustical signal, and sound source power circuit (2) is that sound source (1) provides power supply,
PA-system power circuit (4) is that PA-system (3) provides power supply.
By above-mentioned radio connection, the wiring link during movie theatre is built can be exempted, the substitute is and be only required to be often
Only being around audio amplifier and lay mains supply, power-supply wiring is not required to connect up by surround speaker quantity, only need to lay one so that execute
Work cost is effectively controlled.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, not
On the premise of departing from the invention design, it is also possible to making some deformation and improvement, these broadly fall into the protection model of the present invention
Enclose.
