Abstract
One kind one drags four wireless microphone systems, including receiver and two wireless microphones, it is characterised in that：The wireless microphone is separately connected a wire microphone.The miaow core of the wire microphone is connected with 3.5 stereo contact pins, it is inserted into the stereo base of pcb board 3.5 of wireless microphone, it is in parallel with the miaow core of wireless microphone, the signal of wire microphone and wireless microphone is input to pre-amplification circuit simultaneously, is connected to transmitting antenna module through audio processing modules, wireless transmission mode.The wire microphone is moving-coil type or Electret Condencer Microphone.Its advantage is that four microphones are wirelessly connected with receiver simultaneously, the disconnected frequency phenomenon of interference will not be generated.
Description
Technical field
The utility model relates to the structures for combining several sensors, and espespecially one kind one drags four wireless microphone systems.
Background technique
The existing 2.4G wireless microphone of existing market, can only two sets use simultaneously, two sets used above to will appear the disconnected frequency of interference
Phenomenon.
Summary of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is to provide one kind one to drag four wireless microphone systems.
Four microphones are aimed to carry out that interference disconnected frequency phenomenon will not be generated when Wireless transceiver.
Technical solution adopted by the utility model to solve its technical problems is：One kind one is provided and drags four wireless microphone systems
System, including receiver and two wireless microphones, it is characterised in that：The wireless microphone is separately connected a wired Mike
Wind.
The miaow core of the wire microphone is connected with 3.5 stereo contact pins, and the pcb board 3.5 for being inserted into wireless microphone is three-dimensional
Initial consonant seat, it is in parallel with the miaow core of wireless microphone, the signal of wire microphone and wireless microphone is input to preceding storing simultaneously
Big circuit is connected to transmitting antenna module through audio processing modules, wireless transmission mode.
The wire microphone is moving-coil type or Electret Condencer Microphone.
Two wireless microphones drag a moving-coil type or condenser type wire microphone respectively, four Mikes connected in this way
Wind is wirelessly connected by wireless microphone and receiver.
The utility model has the beneficial effects that：Four microphones are wirelessly connected with receiver simultaneously, will not be generated dry
Interruption frequency phenomenon.
Detailed description of the invention
The utility model will be further described with reference to the accompanying drawing.
Fig. 1 is Tthe utility model system structural schematic diagram.
Fig. 2 is Tthe utility model system functional-block diagram.
In Fig. 1：1 it is receiver, 21 be the first wireless microphone, 22 be the first wire microphone, 23 is the second wireless wheat
Gram wind, 24 are the second wire microphone.
Specific embodiment
Referring to attached drawing, the utility model one kind one drags four wireless microphone systems, including receiver 1 and two wireless Mikes
Wind 21,23, it is characterised in that：The wireless microphone 21,23 is separately connected wire microphone 22,24.
In the embodiments of the present invention：
The miaow core of the wire microphone 22,24 is connected with 3.5 stereo contact pins, is inserted into the PCB of wireless microphone 21,23
The stereo base of plate 3.5, it is in parallel with the miaow core of wireless microphone 21,23, by wire microphone 22,24 and wireless microphone 21,
23 signal is input to pre-amplification circuit, is connected to transmitting antenna module through audio processing modules, wireless transmission mode simultaneously.
The received machine 1 of two-way wireless signal receives, and arrives signal output, again to audio processing modules to realize four microphones
It works at the same time.
The wire microphone 22,24 is moving-coil type or Electret Condencer Microphone.
Two wireless microphones 21,23 respectively after one moving-coil type of connection or condenser type wire microphone 22,24 with receiver
It is wirelessly connected, four connected in this way microphone while being used, interference will not be generated.
