Description
Technical field
Sound appliances control technology field is the utility model is related to, is related specifically to a kind of remote-control radio wheat connection control system
System.
Background technology
Audio amplifier is the terminal of whole sound system, and its effect is that audio electric energy is converted into corresponding acoustic energy, and its spoke
Space is mapped to go.It is the extremely important part of sound system, because it is responsible for is transformed into acoustical signal confession electric signal
The ear of people directly listens to so mission critical, and the sense of hearing that it will be directly with people is come into contacts with, and the sense of hearing of people is very clever
Quick, and there is very strong resolving ability to the tone color of complex sound.
With the development of science and technology, the remote control of existing speaker products all separates with wireless microphone, cost is high
Also result in audio amplifier peripheral accessory and do not allow manageability excessively, while also inconvenience is used, and puzzlement is brought to user.Meanwhile microphone
Or control mode is using infrared connection, or being connected using mode of frequency regulation, the former propagation distance is shorter, can only cover 7-8m's
Farther out, but easily there is the phenomenon of string frequency in radius, the latter's propagation distance.
The content of the invention
The technical problems to be solved in the utility model is：A kind of remote-control radio wheat connection control system is provided, realizes remote control
The combination of device and microphone, and solve the problems, such as long-distance transmissions and string frequency.
The technical solution of the utility model is：A kind of remote-control radio wheat connects control system, including wireless wheat and sound equipment dress
Put, the wireless wheat is provided with control panel and wireless transmitter module, and the control panel electrically connects with wireless transmitter module, described
PA-system is provided with wireless receiving module, decoding control block and sound equipment power amplifier module, wireless receiving module and the sound equipment work(
Amplification module electrically connects with decoding control block；The wireless transmitter module includes infrared connection unit and high frequency carrier unit,
The wireless transmitter module and wireless receiving module first pass through it is infrared to frequency, then by high frequency mode of frequency regulation transmission of control signals with
Processing is identified in audio signal, the signal that decoding control block receives wireless receiving module, passes through sound equipment power amplifier module
Corresponding control command is performed, while the audio signal to receiving carries out the broadcasting that amplifies.Carried out using infrared ray closely
The matching of identification code and for the first time to frequency, effectively prevent go here and there frequency phenomenon；Recycle high frequency carrier mode of frequency regulation to be transmitted, will control
Signal, to PA-system, realizes long-distance transmissions with audio signal transmission.
Preferably, the high frequency carrier unit passes through V sections frequency modulation or U section frequency modulation.
Further, the decoding control block is connected with USB interface and/or TF card groove.
As a further improvement, the decoding control block is provided with sound identification module, the control panel, which is provided with, to be used
In the switching switch of switching microphone pattern or Voice command pattern；After Voice command pattern being switched to by the switching switch,
Wireless transmitter module transmits speech-controlled information to wireless receiving module, and decoding control block utilizes sound identification module by nothing
Speech-controlled information Intelligent Recognition that line receiving module receives simultaneously is converted to corresponding control command, passes through sound equipment power amplifier module
Perform corresponding control command.By speech recognition with control, can be achieved switching song, song search, special sound effect (applaud,
Cheer audio) play etc. function.
The beneficial effects of the utility model are：Using infrared ray closely be identified code matching and for the first time to frequency,
Effectively prevent string frequency phenomenon；High frequency carrier mode of frequency regulation is recycled to be transmitted, by control signal and audio signal transmission to sound
Device is rung, realizes long-distance transmissions.
