Description

The transponder that the audio signal of overlapping video conferencing system is transmitted mutually
Technical field
The utility model relates to the transponder that a kind of audio signal that will overlap video conferencing system is transmitted mutually.
Background technology
Continuous development along with network, the application of network teleconference system is also more and more, the company that causes developing network video conference device also gets more and more, because the equipment and the disunity of each company's exploitation, so tend to use the different network teleconference system equipment of two covers in same meeting-place, for example, one cover is applicable to the meeting that participates in each place department, one cover is applicable to the meeting that participates in each provincial department, yet when each place department and provincial department hold same meeting simultaneously, this meeting-place just need be with unified use of the different conference system equipment coordinations of two covers, make two cover conference system equipment adopt same audio playing apparatus and audio collecting device in this locality, and the audio signal that different conference systems produce can be transmitted mutually, therefore, how will overlap unified use of video conferencing system equipment coordination more and become the technical task that those skilled in the art need to be resolved hurrily in fact.
The utility model content
The transponder that provides a kind of audio signal that will overlap video conferencing system simple in structure and with low cost to transmit mutually is provided the purpose of this utility model more.
In order to achieve the above object, the transponder that the audio signal that will overlap video conferencing system that the utility model provides is transmitted mutually, wherein, many cover video conferencing systems are shared same set of audio playing apparatus and audio signal sample device in this locality, and described transponder comprises: be respectively applied for first interface that is delivered to the respective number that local audio signal is connected with corresponding many cover video conferencing systems; Be used for second interface that is connected with described audio playing apparatus; Be used for the 3rd interface that is connected with described audio signal sample device; After amplifying through computing, the audio signal that is used for that each described first interface is inserted sends into first operational amplifier of described second interface; Be respectively applied for the audio signal that will insert and carry out a plurality of second operational amplifiers that computing is amplified with the audio signal that inserts from described the 3rd interface from first interface of a corresponding video conferencing system correspondence; Be respectively applied for a plurality of the 4th interfaces that the audio signal of described a plurality of second operational amplifier outputs are delivered to corresponding other video conferencing systems; Power unit to each operational amplifier power supply; Wherein, the number of the number of described first interface and described second interface is relevant with the tricks of video conferencing system.
Wherein, the tricks of video conferencing system is two covers, and the number of corresponding second operational amplifier and the 4th interface all is 2.
Preferably, described power unit comprises voltage stabilizing circuit and filter circuit.
In sum, the transponder that the audio signal that will overlap video conferencing system of the present utility model is transmitted mutually can be realized the forwarding of the audio signal of different video conference system by simple several operational amplifiers, it is simple in structure, and is with low cost, and easy to use.
Description of drawings
Fig. 1 is the circuit theory diagrams of the transponder transmitted mutually of the audio signal that will overlap video conferencing system of the present utility model more.
Embodiment
See also Fig. 1, the transponder that the audio signal that will overlap video conferencing system of the present utility model is transmitted mutually comprises at least: a plurality of first interfaces, second interface, the 3rd interface, first operational amplifier, a plurality of second operational amplifiers, a plurality of the 4th interfaces, and power unit, be simplified illustration, in the present embodiment, so that the audio signal of two cover video conferencing systems (i.e. first video conferencing system and second video conferencing system) is transmitted is that example describes in detail, corresponding first interface, the number of the 4th interface and second operational amplifier all is 2, wherein, described two cover video conferencing systems are shared same set of audio playing apparatus and audio signal sample device in this locality, promptly shared same set of loudspeaker and microphone.
Two first interfaces are respectively applied for the audio signal that is delivered to this locality with corresponding many cover video conferencing systems and are connected, promptly the first interface A is used for being delivered to local audio signal with first video conferencing system and is connected, and the first interface B is used for being delivered to local audio signal with second video conferencing system and is connected.
