Detailed description of the invention
Fig. 1 is the functional block diagram of the visual sound system of microphone channel on off operating mode of the present invention with coding.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in Figure 1, a kind of sound system that the microphone channel on off operating mode of band coding is visual, including microphone and tuning
Platform, the microphone input interface connection on the output end and sound console of microphone are equipped with acoustic-electric conversion circuit in microphone.
It is serial that superaudio signal generating circuit, microphone coding generative circuit, microphone coding are additionally provided in microphone of the invention
Output circuit, microphone encode display circuit, modulation circuit, hybrid circuit, mixed signal processing circuit.
Microphone encode generative circuit generate encoded signal, encoded signal be transferred to respectively microphone coding serial output circuit and
Microphone encodes display circuit, what the encoded signal and superaudio signal generating circuit that microphone coding serial output circuit generates generated
Superaudio signal inputs modulation circuit together, and encoded signal is modulated the superaudio signal as carrier frequency by modulation circuit,
The modulated signal of generation inputs hybrid circuit, while audio signal is inputted hybrid circuit by acoustic-electric conversion circuit, and hybrid circuit will
Modulated signal and audio signal input mixed signal processing circuit after mixing, and mixed signal processing circuit is by mixed signal
Microphone input interface is transferred to after processing.

Remaining modulated signal inputs demodulator circuit after number filter and amplification, and modulated signal is demodulated encoded signal by demodulator circuit, and will
Encoded signal inputs microphone coding and reads display circuit, and microphone coding reading display circuit receives encoded signal and shows that microphone is compiled
Code, otherwise then shows error code.
The visual sound system of the microphone channel on off operating mode with coding of the invention is in use, microphone first in microphone
It encodes generative circuit and generates coding to microphone, this coding can be arbitrarily arranged on microphone, but used in same sound console
Two microphones coding cannot be identical, by encoded signal together with superaudio signal modulation after, then modulated signal and microphone picked up
The audio signal taken mixes, and is transferred to the corresponding microphone input interface of sound console after treatment.The mixed signal
Two-way is divided by signal distribution circuit, is used for script function all the way, another way is used to judge the break-make situation of microphone channel.And it talks about
The judgement of cylinder channel break-make situation mainly utilizes, the modulated signal that the modulation circuit being arranged in microphone generates, if be transferred to
Judge on sound console.For specifically mixed signal after filter and amplification, audio signal is filtered out remaining modulated signal, the tune
Signal processed is demodulated circuit and is demodulated to encoded signal, and wherein encoded signal input microphone coding reads display circuit and shows, at this time
Tuner is in sound console, so that it may directly observation obtains the break-make situation of the encoding microphone, if microphone channel normally if microphone encode
It reads display circuit and shows microphone coding, if microphone channel is faulty, show error code, because it is known that all microphones are compiled
Code, removes microphone working properly, is known that the coding of the obstructed microphone of channel, recording engineer timely can accurately locate
Reason, to ensure that the normal use of sound system.
Filter circuit is concatenated between the signal distribution circuit and audio signal processing circuit of the present embodiment, which will
It may be entrained in encoded signal in audio signal, superaudio target signal filter, exclusion may be to the influence of voice signal.
It is sine wave that frequency range is 21Khz~30Khz that the superaudio signal generating circuit of the present embodiment is generated
Signal.
The percentage of superaudio signal level and audio signal maximum level that superaudio signal generating circuit generates is less than
20%, which not only can guarantee that subsequent circuit can detect superaudio signal, but also can reduce superaudio signal to the greatest extent to sound
The issuable interference of frequency signal.
The coding that the microphone coding generative circuit of the present embodiment generates is adjustable；Microphone coding reads the display circuit period
Property reading encoded signal, if receive encoded signal just show microphone encode, do not receive encoded signal and show error code.
In conclusion the sound system visual with the microphone channel on off operating mode encoded of the invention can be in system equipment
In the case where opening, the on-off of real-time, continual display microphone to the entire channel of sound console.If between having among channel
It is disconnected, then conducting will be displayed without on sound console, illustrate it is faulty, it is on the contrary then show conducting, illustrate microphone at sound console
In normal operating conditions, and the microphone number that channel can also be made to be connected is shown, so that it will also be appreciated that those are encoded
Microphone channel it is problematic, if microphone is not turned on, failure can be timely discharged in tuner, or allow using talk about
The people of cylinder replaces a microphone, avoids the occurrence of and begins to use the case where just discovery cannot be connected, so that improving sound system makes
Reliability.
It a possibility that present invention greatly improves sound system reliability, reduces sound equipment accident, improves work efficiency,
And the working strength of staff can be mitigated, huge sound system market is given, relatively good economic and social benefit is brought.
The preferred embodiment of present invention described above, is not intended to limit the invention, it is all in spirit of the invention and
