Abstract
A hand in hand wireless microphone system disclosed by the utility model comprises wireless microphones and receivers, and each receiver is a wireless microphone receiver, is equipped with one or more than one wireless reception channels and outputs to an arranged mixed audio output end. Each receiver is equipped with an expansion module, the expansion module is equipped with an input interface and an output interface, and the wireless reception channels are connected with the output interface. One receiver is connected with the input interface of another one receiver via the output interface to be in series expansion connection, and an audio signal is outputted from the mixed audio output end of the receiver at the tail end. According to the utility model, the wireless microphone products having the configurations, such as, the wireless microphone product having one receiver and four wireless microphones, the wireless microphone product having one receiver and eight wireless microphones, etc., can be combined at will, and the hand in hand wireless microphone system is simple and practical in structure.
Description
Technical field
The utility model relates to the wireless microphone technical field, especially a kind of wireless microphone system hand in hand that can combine many wireless microphone receivers.
Background technology
At present, wireless microphone product on market, can be divided into one-to-one, one drag two, by its configuration drags four, one to drag the products such as eight, its difference is: the one-to-one wireless microphone comprises a receiver and a wireless microphone, receiver only has a wireless receiving passage, therefore can only receive the signal of a road wireless microphone, that is to say, synchronization can only allow a people to use; The one drag two wireless microphone comprises a receiver and two wireless microphones, and receiver has two wireless receiving passages, therefore can receive the signal of two road wireless microphones, that is to say that synchronization can allow two people to use.One drags four, one to drag the wireless microphones such as eight the rest may be inferred.But one drags four, one to drag the products such as eight, and technical difficulty is large, stability, reliability be difficult to guarantee, cost is also high, and market demand is few, and application scenario is few, " maintains an army for a thousand days, is used in for the moment " often, causes the waste of resource.
Along with social progress, wireless microphone is also day by day universal, the large-scale occasion that many people perform simultaneously is also increasing, can connect by simple, many wireless microphones are combined, realize that one drags four, one to drag eight, even more, this becomes the new bright spot of wireless microphone product at present, and " handing in hand " function of wireless microphone is arisen at the historic moment.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of wireless microphone system hand in hand, by expansion module, connects and expands many wireless Mike's receivers, realizes that hand drags hand to use many wireless microphones simultaneously.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of wireless microphone system hand in hand, comprise wireless microphone and receiver, described receiver is wireless microphone receiver, be provided with one or above wireless receiving passage and output to the mixed audio output of setting, described receiver is provided with expansion module, described expansion module is provided with connected input interface and output interface, the wireless receiving passage is connected with output interface, receiver is connected on the input interface of another receiver the expansion of connecting and connects by output interface, audio signal is from the mixed audio output output of the receiver of end.
Further improvement in the technical proposal, described input interface is provided with audio input end and output interface is provided with audio output, audio input end is connected to audio output by the first amplifier output arranged, and the wireless receiving passage is connected to the output of the first amplifier.
Further improvement in the technical proposal, also be respectively equipped with power input and earth terminal on described input interface and output interface.
Further improvement in the technical proposal, the wireless receiving passage of described receiver is provided with the second amplifier, and the output amplifying signal is to the mixed audio output.
The beneficial effects of the utility model: a kind of wireless microphone system hand in hand of the utility model, by increase expansion module on receiver, input interface and output interface are set on expansion module, the output interface of a receiver is connected to the input interface of another receiver, realize many wireless microphone receivers of series connection expansion, audio signal mixed transport is successively exported to the receiver of end, simple and practical, greatly reduce and drag four, one cost that drags the wireless microphone products such as eight, range of application is wider, enhances competitiveness.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Fig. 1 is principle schematic of the present utility model.
Fig. 2 is functional-block diagram of the present utility model.
Embodiment
See figures.1.and.2, the utility model provides a kind of wireless microphone system hand in hand, comprise wireless microphone 21 and receiver 2, described receiver 2 is wireless microphone receiver, be provided with one or above wireless receiving passage 22 and output to the mixed audio output 23 of setting, receiver 2 is provided with expansion module 1, described expansion module 1 is provided with input interface 11 and output interface 12, be respectively equipped with power input and earth terminal on input interface 11 and output interface 12, connect respectively power supply to expansion module 1 power supply and ground connection, while input interface 11 is provided with audio input end and output interface 12 is provided with audio output, audio input end connects and outputs to audio output by the first amplifier 13 arranged, described the first amplifier 13 is the operational amplifier amplified for preposition audio frequency, sound source signal is amplified, make it keep reasonable Frequency Response and distorted characteristic in audiorange.
Further improve, the wireless receiving passage 22 of described receiver 2 is provided with the second amplifier 24, shown in Fig. 1, in the present embodiment, be provided with two-way wireless receiving passage 22, the operational amplifier that described the second amplifier 24 is audio preamplifier, two-way wireless receiving passage 22 output amplifying signal in parallel is to output interface 12 and mixed audio output 23.
In the utility model, pass through to increase expansion module 1 on receiver 2, receiver 2 is connected to by output interface 12 and carries out expansion continuously on the input interface 11 of another receiver 2 and connect, realize many wireless microphone receivers of series connection expansion, each receiver 2 receives its signal from wireless microphone 21, audio signal is mixed successively through expansion module 1 transmission, finally from mixed audio output 23 outputs of the receiver 2 that is connected to end.One drags the execution mode of four wireless microphone systems to be, by two the one drag two receivers of connecting, the output interface 12 of First receiver 2 is connected to the input interface 11 of second receiver 2, audio signal is from mixed audio output 23 outputs of second receiver 2, the rest may be inferred, four the one drag two receivers 2 of connecting realize that one drags eight wireless microphone systems, simple and practical, only need on wireless microphone receiver, increase expansion module 1, not only reliably but also convenient, can arbitrarily be combined into large-scale wireless microphone system and use.
