The invention discloses the noise silence processing system of a kind of wireless microphone and main frame, it is included：An at least wireless microphone, the encoder in the microphone main body is arranged at a microphone main body and one；One main frame, the decoder in the host main body is arranged at a host main body and one；When the wireless microphone sends a radiofrequency signal, by the subsidiary password of the encoder in the radiofrequency signal, when the main frame receives the radiofrequency signal, the incidental password of the radiofrequency signal is understood by the decoder, if password is correct, exports audio signal, if password bad, silence processing then is carried out without exporting to audio signal, to avoid producing noise.
Description
Technical field
The present invention is relevant with wireless microphone relevant device, and in particular to a kind of wireless microphone
With the noise silence processing system of main frame.
Background technology
Matching method typically between wireless microphone and main frame sends spy for setting wireless microphone
Fixed frequency (such as 801.00MHZ), then specific frequency (such as 8 is received by main frame
01.00MHZ), consequently, it is possible to just complete the pairing between wireless microphone and main frame.
However, under same environment, if there is close frequencies (such as 801.025MHZ)
Wireless microphone in use, because its frequency is close, main frame can also receive the signal and enter
And send, so that the problem of readily receiving close frequencies signal and then produce noise.
The content of the invention
In view of this, to improve in the prior art, main frame easily receives the wireless of close frequencies
Radiofrequency signal, and then the problems such as generation noise；The invention provides a kind of wireless microphone with
The noise silence processing system of main frame, it is included：An at least wireless microphone, with a wheat
Gram wind main body and one it is arranged at encoder in the microphone main body；One main frame, with a master
Machine body and one it is arranged at decoder in the host main body；When the wireless microphone sends one
During radiofrequency signal, by the subsidiary password of the encoder in the radiofrequency signal, when the main frame connects
When receiving the radiofrequency signal, the incidental password of the radiofrequency signal is understood by the decoder,
If password is correct, exports audio signal, if password bad, to audio signal
Silence processing is carried out without exporting, to avoid producing noise.
In one embodiment of this invention, the electricity of the circuit of the microphone main body and the encoder
Road is integrated, and its handling process is that DATA coding circuits are programmed by a micro-processor interface circuit,
One password is provided, then after a phase-locked loop circuit and RF concussions and modulation circuit,
Sent again by a RF amplifiers, so as to be accompanied with the radiofrequency signal sent specific close
Code.
In one embodiment of this invention, the circuit of the circuit of the host main body and the decoder
Integrate, its handling process is received with intermediate-frequency circuit by a high frequency and sent by wireless microphone
Radiofrequency signal simultaneously demodulates audio signal and incidental password, and audio signal is via an audio
Amplifier is handled, and password enters row decoding by a DATA decoding circuits, and micro- by one
Processor circuit carries out interpretation, if its password and the password not match of setting, its audio letter
Number by a muting control circuit block and without audio output, if password with set it is close
Code-phase is accorded with, then its audio signal carries out audio output by an audio amplification path.
In one embodiment of this invention, the audio signal that the wireless microphone is sent is RF
Radio signal.
The wireless microphone and the noise silence processing system of main frame that the present invention is provided receive non-
During the audio signal for the close frequencies that pairing wireless microphone is sent, sentencing for password can be first passed through
Read, then decide whether output.When the interpretation of password is not inconsistent, main frame can be by its audio signal
It is considered as noise and carries out silence processing, so as to prevents output noise.

Embodiment
Further understand and recognize to enable auditor to have the feature of the present invention with its feature
Together, hereby enumerate following preferred embodiment and coordinate schema to be described as follows：
A kind of wireless wheat provided as shown in Figures 1 and 3 by a preferred embodiment of the present invention
The noise silence processing system 100 of gram wind and main frame, consists predominantly of at least one wireless Mike
The main frame 20 of wind 10 and one, wherein：
As shown in figure 1, there is the wireless microphone 10 microphone main body 11 and one to set
Encoder 12 in the microphone main body 11.
As shown in figure 1, there is the main frame 20 host main body 21 and one to be arranged at the main frame
Decoder 22 in body 21.
Above-mentioned is a kind of wireless microphone and main frame that a preferred embodiment of the present invention is provided
Each portion's component of noise silence processing system 100 and its assembling mode introduction, then again will
Its handling characteristics is described as follows：
In the present embodiment, the circuit that the circuit of the microphone main body 11 can be with the encoder 12
Integrated.As shown in Fig. 2 its handling process is to DATA by a microcontroller circuit
Coding circuit is programmed there is provided a password, then by a phase-locked loop circuit and a RF
Concussion believes sent radio frequency with after modulation circuit, then being sent by a RF amplifiers
Specific password is accompanied with number.
Then, in the present embodiment, the circuit of the host main body 21 can be with the decoder 22
Circuit is integrated.As shown in figure 3, its handling process is to be connect by a high frequency and intermediate-frequency circuit
Receive the radiofrequency signal sent by wireless microphone and demodulate audio signal and incidental close
Code, audio signal is handled via an audio-frequency amplifier, and password decodes electricity by a DATA
Row decoding is entered on road, and carries out interpretation by a microcontroller circuit, if its password and setting
Password not match when, then its audio signal is blocked by a muting control circuit, and without sound
Frequency is exported, if password is consistent with the password set, and its audio signal passes through an audio
Amplification path and carry out audio output, i.e., from a loudspeaker 30 output (as shown in Figure 1).
Thereby, if the main frame in the present invention receives the phase that non-matching wireless microphone is sent
During the audio signal of nearly frequency, the interpretation of password can be first passed through, then decides whether output.When
When the interpretation of password is not inconsistent, its audio signal can be considered as noise and carry out silence processing by main frame,
To prevent output noise.
The above takes off preferred embodiment only provided by the present invention, and is not used to limitation
The practical range of the present invention, all relevant arts in the art are according to carried out by the present invention
Equivalent change, should all belong to the scope that is covered of the present invention.
