Description
Technical field
It is the present invention relates to stereo set technical field more particularly to a kind of with showing microphone channel on off operating mode function
Sound system.
Background technology
Sound system device is that, using most media devices, particularly have in industries such as education, business, amusement, exhibitions
And be widely applied.
Sound system mainly includes microphone, sound console, power amplifier and audio amplifier etc., and the sound system Jing for currently using often occurs one
Individual problem:Start speech using the people of microphone, it is found that microphone can not send out sound, affect the quality of items on the program, waste time,
There is the thing that such case is that tuner most worries, but this performance accident is difficult to avoid, and is exactly to do again many preparations in advance
Work, still has such case generation.
The noiseless common cause of microphone is:The power switch of microphone is closed or silence switch pass using the people of microphone
Close, the contact of the connector of microphone line is bad, situations such as microphone battery has not had electric.Although tuner can carry out before start
Sufficient debugging efforts, but one it is movable in personnel are various, be pressed for time, and many people are not familiar with the using method of microphone
Etc. reason, break down and be difficult to avoid.
Tuner when microphone is tested usually is input into a voice signal at microphone end, then listens audio amplifier to have again
Without voice output, but it is impossible to so test after program starts, tuner cannot detect that microphone leads sound console
Whether whole flow process is normal, if so after program starts, microphone goes wrong, it is impossible to find in time, microphone just occurs not
Go out the situation of sound, what impact amplified is normally carried out, and wastes the time, have impact on effect, causes irretrievable loss sometimes.

It is placed near pickup device.
The superaudio signal that superaudio signal generating circuit is generated is converted into superaudio voice signal by electroacoustic transducer, picks up
Sound device also picks up the superaudio voice signal that transducer sends in addition to picking up normal voice signal, and pickup device is defeated
The signal that excess of export audio signal and audio signal are mixed will mix letter to pickup signal process circuit, pickup signal process circuit
Number process after be input into sound console microphone input interface.
The present invention sound console in be provided with electrically connect with microphone input interface signal distribution circuit, filter amplification circuit,
Detection display circuit, filter circuit, audio signal processing circuit.
By the mixed signal input signal distributor circuit for receiving, signal distribution circuit is by mixed signal for microphone input interface
It is divided into two-way, all the way input filter circuit, is left audio signal input audio signal process circuit after filtering afterwards, another road is defeated
Enter filter amplification circuit, input detection shows filter amplification circuit after remaining superaudio signal amplification after audio signal is filtered
Circuit, detection display circuit receive superaudio signal and show conducting, otherwise show and are not turned on.
When using with the sound system for showing microphone channel on off operating mode function of the present invention, the Supersonic arranged in microphone
The superaudio signal that frequency signal generating circuit will be generated, is transferred to electroacoustic transducer, is converted into superaudio sound by electroacoustic transducer
Sound is transferred to pickup device by air medium.Pickup device also picks up the voice signal of microphone environment, two kinds of sound simultaneously
All arrived by the pickup of pickup device, and electric signal transmission is converted into by pickup device and give pickup signal process circuit, by pickup signal
The microphone input interface of sound console is input into after processing circuit processes.Above-mentioned mixed signal is divided into two-way by signal distribution circuit, and one
Road is used for the script function of microphone, another break-make situation for being used to judge microphone channel.And microphone channel break-make situation is sentenced
It is disconnected to mainly use, the superaudio signal generated by the superaudio signal generating circuit arranged in microphone, specifically mixed signal
After amplifying after filtering, audio signal is filtered and is left for surveying logical superaudio signal.When microphone channel open, mixing letter
Number Jing after signal distribution circuit, filter amplification circuit, it is left superaudio signal, is then passed to detect that display circuit shows break-make shape
State;When microphone channel is faulty, no mixed signal is transferred to microphone input interface, would not have behind filter amplification circuit
Superaudio signal, detection display circuit just show and are not turned on.Tuner can directly observe on sound console and draw the logical of microphone
Disconnected situation, just can be processed once microphone is faulty, in time so as to ensure that the normal use of sound system.

Signal.
The superaudio signal level that superaudio signal generating circuit is generated is less than with the percentage of audio signal maximum level
20%, the percentage both can guarantee that circuit below can detect superaudio signal, can reduce superaudio signal again as far as possible to sound
The issuable interference of frequency signal.
In order to further improve the reliability that sound system is used, the disadvantage brought that breaks down when using further is avoided
End, the present embodiment are provided with indicator lamp on microphone, and the indicator lamp is serially connected between the output end of microphone and microphone input interface.
Namely when microphone channel is in the state of leading to, indicator lamp is just lit.And whether the indicator lamp on microphone is lighted, right and wrong
Often significantly on off operating mode is indicated, is allowed user and debugging Shi Junke quickly to judge, is timely processed.
Current sound system is generally all that, with multiple microphones, sound console is provided with multiple microphone input interfaces, also
It is microphone and the one-to-one setting of microphone input interface.And the present invention's in order that all microphone channel break-make situations are visual, often
It is equipped with superaudio signal generating circuit, hybrid circuit and pickup signal process circuit in individual microphone, and in sound console successively
The signal distribution circuit of connection, filter amplification circuit and detection display circuit can be arranged to multichannel.Signal distribution electricity per road
Road and the one-to-one connection of microphone input interface.Certainly do not limit it is above-mentioned cited, as long as can have that microphone channel break-make shape is realized
State is visual.
In sum, the sound system with display microphone channel on off operating mode function of the invention can be in system equipment
It is in the case of opening, real-time, continual to show microphone to the break-make of the whole passage of sound console.If between having in the middle of passage
It is disconnected, then conducting will to be displayed without on sound console, is illustrated faulty, otherwise is then shown conducting, illustrate microphone at sound console
In normal operating conditions.If microphone is not turned on, then tuner timely discharging failure, or can allow and use microphone
People change a microphone, it is to avoid occur beginning to use the situation that just discovery can not be turned on.
The present invention greatly improves sound system reliability, reduces the possibility of sound equipment accident, improves operating efficiency,
And the working strength of staff can be mitigated, to huge sound system market, bring reasonable economic and social benefit.
