With sound module on the transmit control module of equipment synchronous sound more than is also set, as long as need to play same song between multiple and sound box simultaneously, and each music box can not life period delay variance when playing same song, people is allowed to feel the sound that same audio amplifier plays out, now then wireless network can be passed through, send instruction and act on many equipment synchronous sound transmit control module, make multiple background music box realize this function.Meet some in particular cases needs multiple background music box synchronous sound situations about coordinating with light, the situation that music is coordinated with light is more diversified.
This background music box arranges the treatment circuit to power supply, AC power is converted to the direct supply being applicable to using with sound module, then supply and sound module work, simultaneously and the operation of sound module realized by wireless network, without the need to complexity wiring, only need can realize allowing and sound module work by wireless network, background music is provided, eliminate loaded down with trivial details wired program, greatly reduce the maintenance difficulties of background music box.
Described many equipment synchronous sound transmit control module be used for ensureing and sound box can with other and sound box played songs synchronous sound.
Described and sound module comprises MCU processor, wireless interface module, hard disk, DDR internal memory, and wireless interface module wherein, hard disk and DDR internal memory are all connected on MCU processor.The setting of wireless interface module realizes the reception of signal command by wireless network, then pass to MCU processor and process signal command, and sound module makes corresponding reaction, has line traffic control to carry out ratio with existing, eliminates major part wiring.
Described ON-OFF control circuit is also arranged live wire to export and zero line output.Human body is avoided to be not intended to touch this equipment and occur potential safety hazard.
Live wire input and zero line input are also set between described AC power supplies circuit and ON-OFF control circuit.
Described AC power supplies circuit is that 220V interchange turns direct current 12V circuit.The interchange point that outside supplies is converted into the direct current that can use, and protection device normally works.
Described DC power circuit is isolated buck filtering voltage regulation 5V output circuit.Too high voltages is avoided to damage and sound module.
Compared with prior art, the invention has the beneficial effects as follows:
1, the setting of wireless interface module realizes the reception of signal command by wireless network, then pass to MCU processor to process signal command, corresponding reaction is made with sound module, have line traffic control to compare with existing, connect up without the need to complexity, only need can realize allowing the work of background music box by wireless network, eliminate loaded down with trivial details wired program, greatly reduce the maintenance difficulties of background music box.
2, with sound module on the transmit control module of equipment synchronous sound more than is also set, as long as need to play same song between multiple and sound box simultaneously, and each music box can not life period delay variance when playing same song, people is allowed to feel the sound that same audio amplifier plays out, now then wireless network can be passed through, send instruction and act on many equipment synchronous sound transmit control module, make multiple background music box realize this function.Meet some in particular cases needs multiple background music box synchronous sound situations about coordinating with light, the situation that music is coordinated with light is more diversified.
