Abstract
The utility model discloses a wireless surround speaker is used to cinema, including the sound source device, sound source device power supply circuit, PA -system and PA -system power supply circuit, the sound source device includes audio frequency input interface, audio frequency processing module, wireless transmitting module, the PA -system includes the wireless receiving module, power amplifier, loudspeaker system, through above -mentioned wireless connection, can exempt cinema wiring link under construction, the substitute is only needs to lay mains supply for every surround speaker, the wiring of surround speaker quantity need not pressed to the power -supply wiring, only need lay one can, make construction cost be effectively controlled.
Description
Technical field
The present invention relates to a kind of sound equipment, particularly a kind of movie theatre private radio surround speaker.
Background technology
Current known movie theatre surround speaker system is made up of passive passive sound box and power amplifier, passive loudspeaker box is lifted on the design attitude of movie theater surround channel, power amplifier is placed in special projection booth, the two is linked together by the audio power line laid in advance, and this known technology exists following imperfection part:
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 accept.
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, nearly tens of up to a hundred surround speakers, wiring installation is extremely complicated, and therefore design difficulty and construction cost are all higher, are unfavorable for cost control;
Summary of the invention
The object of this invention is to provide a kind of movie theatre Wireless surrounding audio amplifier, with at least one in solving the problems of the technologies described above or all.
According to an aspect of the present invention, provide a kind of movie theatre Wireless surrounding audio amplifier, comprise sound source, sound source power circuit, acoustics and acoustics power circuit, sound source comprises 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 into audio processing modules, the audio signal that audio processing modules audio reception input interface is sent here is also treated to the signal that wireless transmitter module can identify, send wireless transmitter module to simultaneously, the audio signal that wireless transmitter module audio reception processing module is sent here with carrier system transmitted radio signal, acoustics comprises wireless receiving module, power amplifier, speaker system, wireless receiving module sends into power amplifier after receiving the wireless carrier Audio Signal Processing of sound source transmitting, the audio signal that power amplifier accepts wireless receiving module is sent here is also transferred to speaker system after amplifying this signal, the audio signal that speaker system received power amplifier is brought also converts voice signal to, sound source power circuit provides power supply for sound source, acoustics power circuit provides power supply for acoustics.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of movie theatre Wireless surrounding of the present invention audio amplifier;
Embodiment
Below in conjunction with accompanying drawing, 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 shown in Figure 1, a kind of movie theatre Wireless surrounding audio amplifier, comprises sound source (1), sound source power circuit (2), acoustics (3) and acoustics power circuit (4),
As shown in Figure 1, sound source (1) comprises audio input interface (11), audio processing modules (12), wireless transmitter module (13), audio input interface (11) receives the audio signal of outside input, and the audio signal of input is sent into audio processing modules (12), the audio signal that audio processing modules (12) audio reception input interface (11) is sent here is also treated to the signal that wireless transmitter module (13) can identify, send wireless transmitter module (13) to simultaneously, the audio signal that wireless transmitter module (13) audio reception processing module (12) is sent here with carrier system transmitted radio signal, acoustics (3) comprises wireless receiving module (31), power amplifier (32), speaker system (33), power amplifier (32) is sent into after the wireless carrier Audio Signal Processing that wireless receiving module (31) reception sound source (1) is launched, the audio signal that power amplifier (32) reception wireless receiving module (31) is sent here is also transferred to speaker system (33) after amplifying this signal, the audio signal that speaker system (33) received power amplifier (32) is brought also converts voice signal to, sound source power circuit (2) provides power supply for sound source (1), acoustics power circuit (4) provides power supply for acoustics (3).
By above-mentioned radio connection, can exempt the wiring link in movie theatre construction, the substitute is and be only required to be every surround speaker laying mains supply, power-supply wiring does not need to connect up by surround speaker quantity, only need lay one, construction cost is effectively controlled.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
