Yet, the echo processing mode of at present general accompanying video, mostly be the voice signal that microphone is received to be dubbed in background music with vocal accompaniment directly mix back output broadcast, its singer's sound only can be done simple volume adjustment and echo processing by volume control circuit in this process, the effect process of so-called even lifting Key also is to dub in background music at vocal accompaniment to carry out, and can't do the modification of suitable degree to singer's tonequality, so often some singer's sound often has distortion after putting dialling via accompanying video, stiff phenomenon, not only can't present the gentle originally simple and honest tone color of closing, more therefore, may destroy original level of singing, and can't enjoy oneself to heart's content.
The utility model content
The vacuum treatment installation of the utility model wireless microphone, promptly by the singer is sent with radio frequency via the audio signal of wireless microphone radio reception, after receiving by vacuum treatment installation again, via exporting behind amplifier and the vacuum tube buffer stage signal, processing by vacuum tube makes the tone color of radio reception more clear simple and honest, to improve quality distortion or stiff phenomenon, be its main purpose.
The technical solution of the utility model is:
A kind of vacuum treatment installation of wireless microphone, it includes:
One microphone main body, it is provided with a radio-frequency transmissions module, in order to sound signal is exported;
One vacuum treatment installation includes in order to will receiving the radio frequency receiving group of voice signal, and the microphone audio loop of handling singer's tonequality;
One microphone audio loop includes amplifier, TUBE BUFFER vacuum tube buffer stage and volume control circuit;
The singer by microphone main body receive singer's sound signal, by the radio-frequency transmissions module sound signal is exported, and by the radio frequency receiving group of received of vacuum treatment installation, do the adjustment that signal amplifies through amplifier, and enter TUBEBUFFER vacuum tube buffer stage, and the input volume control circuit carries out the volume control and treatment.
This vacuum treatment installation can be provided with one or more radio frequency receiving group.
This vacuum treatment installation joins with an enlarger and loudspeaker.。
This vacuum treatment installation and a main system of audio join.
This main system of audio includes in order to handling the audio loop of dubbing in background music that vocal accompaniment is dubbed in background music, and will make the ECHO echo audio that echo handles through the microphone signal that vacuum buffer is handled at last and handle, and the signal of dubbing in background music of accompanying is integrated the mixing amplifying stage of output mutually.
Be provided with tone controller and amplified signal level in regular turn in this audio loop of dubbing in background music.

Embodiment
For the clear structure of the present utility model of your auditor is formed, and the overall operation mode, cooperate graphic being described as follows now:
The vacuum treatment installation of the utility model wireless microphone, the electronic loop of its whole processor as shown in Figures 1 and 2, mainly include in order to microphone main body 1 that receives singer's sound signal and the vacuum treatment installation 2 that receives sound signal, wherein, be provided with a radio-frequency transmissions module 11 in the microphone main body 1, in order to sound signal is exported; Then include in the vacuum treatment installation 2 in order to radio frequency receiving group 21 that will receive sound signal and the microphone audio loop of handling singer's tonequality.
Wherein, then be provided with amplifier 22, TUBE BUFFER vacuum tube buffer stage 23 and volume control circuit 24 in the microphone audio loop in regular turn.Above-described radio-frequency transmissions module 11, radio frequency receiving group 21, amplifier 22, TUBE BUFFER vacuum tube buffer stage 23 and volume control circuit 24 are known technology, and corresponding commercially available prod is all arranged.
According to this, when microphone main body 1 receive during singer's sound signal, by radio-frequency transmissions module 11 sound signal is exported, radio frequency receiving group 21 by vacuum treatment installation 2 receives again, its singer's sound can be made signal by amplifier 22 earlier and amplify, enter TUBEBUFFER vacuum tube buffer stage 23 subsequently with gentle synaeresis matter, and after entering volume control circuit 24 and carrying out the adjustment of volume control, output more at last, so can allow the operator in the process of singing, the voice signal that in good time changes the singer amplifies, and makes the singer be able to easily performance singing skills originally, and the more soft and graceful tone color of performance; Certainly, this vacuum treatment installation 2 can be illustrated in figure 1 as single body, and is provided with volume controller 25 with the adjustment volume in body, and can comply with required setting of setting up radio frequency receiving group 21, to receive the different frequency that various microphone main body is launched, as shown in Figure 3.
Moreover, because in the electronic loop of the present utility model, mainly also set up a TUBE BUFFER vacuum tube buffer stage 23 at the leading portion in microphone audio loop, not only can make by the driving of vacuum tube tonequality more gentle close simple and honest, and can get rid of distortion or stiff phenomenon for the alt part, and can allow singer's song be able to clear presenting.
Again, also can join through vacuum treatment installation 2 with an enlarger 3 and loudspeaker 5, as shown in Figure 4, enlarge with in addition with sound signal volume that will be after vacuum buffer is handled as the effect of broadcasting, also can be connected with a main system of audio 4, as shown in Figure 5, this main system of audio 4 includes in order to handle the audio loop 41 of dubbing in background music that vocal accompaniment is dubbed in background music, and will do the ECHO echo audio processing 42 that echo is handled through the microphone signal that vacuum buffer is handled at last, and the vocal accompaniment signal of dubbing in background music is integrated the mixing amplifying stage 43 of output mutually, wherein, dub in background music and be provided with tone controller 411 and amplified signal level 412 in the audio loop 41 in regular turn; It can be introduced into the microphone signal of handling through vacuum buffer ECHO echo audio and handle 42 and carry out after sound effect control handles, enter again at last and mix in the amplifying stage 43 and the former vocal accompaniment together output of dubbing in background music, again via loudspeaker 5 with voice output, handle so as to doing suitable echo according to actual singer's tonequality characteristic.
As mentioned above, the vacuum treatment installation of the utility model wireless microphone provides the vacuum treatment installation of another preferable feasible wireless microphone, not only by the wireless transmission sound signal, this sound and through the driving of vacuum tube make tonequality more gentle close simple and honest, so offer the application of novel patent in accordance with the law; But; above implementation and graphic shown in; it is the utility model preferred embodiment; be not to limit to the utility model with this; therefore; all all and the utility model structure, device, feature etc. are approximate, identical, all should belong within the protection range of founding purpose and applying for a patent of the present utility model.
