Specific embodiment
To make the objectives, technical solutions and advantages of the present invention clearer, below by shown in the accompanying drawings
Specific embodiment describes the utility model.However, it should be understood that these descriptions are merely illustrative, and it is not intended to limit this reality
With novel range.In addition, in the following description, descriptions of well-known structures and technologies are omitted, to avoid unnecessarily mixing
Confuse the concept of the utility model.
Here, it should also be noted that, in order to avoid having obscured the utility model because of unnecessary details, in the accompanying drawings
It illustrate only the structure and/or processing step closely related with scheme according to the present utility model, and be omitted practical with this
The little other details of new relationship.
As shown in Figure 1, Figure 2, Figure 3 shows, present embodiment uses following technical scheme: it includes that wireless microphone signal connects
Receipts machine ontology is fixedly installed with phase reversal switch 5 in the front plate 6 of wireless microphone signal receiver ontology, and wireless microphone signal connects
It is fixedly installed with signal output 4 on the backplate 7 of receipts machine ontology, ground terminal 1, hot end are respectively arranged on signal output 4
2, cold end 3；Phase reversal switch circuit, phase reversal switch circuit and phase reversal switch 5 are provided in wireless microphone receiver signal circuit
One end is electrically connected, and the hot end 2 of the other end signal output 4 of phase reversal switch 5, cold end 3 are electrically connected；Phase reversal switch 5 can
Realize the paraphase of wireless microphone audio signal, it is more convenient to use woth no need to replace wiring；
As shown in figure 4, the wiring column device includes conductive shell 8, the body of rod 9, reset spring 10, crimping plate body 11；It leads
The line groove hole 8-1 that front and back penetrates through is offered on electric shell 8, the upper end of line groove hole 8-1 is communicated with jack hole, and the body of rod 9 is flexibly connected
