Fig. 3 is the internal structure schematic diagram of the arrangements of electric connection of a kind of multi-party video communication device of the present invention.
Detailed description of the invention
In conjunction with reference to shown in Fig. 1 and Fig. 2, one multi-party video communication device 100 of the present invention, transmission and conversion for MPTY call, it is mainly made up of microphone jack 1, arrangements of electric connection 2 and surface-mounted integrated circuit (not shown), and this multi-party video communication device 100 is connected with various communication apparatus by arrangements of electric connection 2.Multi-system user can be realized by described conversion line and carry out the purpose of MPTY simultaneously.In the present invention, described communication apparatus is computer system or electrical communication system, for instance can be mike 40, wireless telecommunications system 41, wire communication equipment 42, desk computer 43, notebook 44, microphone 45 and video camera 46 etc..
Fig. 2 illustrates the microphone jack 1 of a kind of multi-party video communication device of the present invention, on it, distribution has several jacks 10, jack 10 exposes to the outside of this multi-party video communication device, for several terminal heads 20 of grafting simultaneously so that the signal of telecommunication between each communication apparatus reaches intercommunication.Described jack 10 can be the interface of various communication apparatus, such as, this communication apparatus interface can be the interface 430 of wireless telecommunications system 41 interface 410, wire communication equipment 42 interface 420, computer 43, to meet the demand of different user, matches with various communication equipments and is connected.
In conjunction with reference to shown in Fig. 2 and Fig. 3, arrangements of electric connection 2 is for controlling the transmission of the signal of telecommunication, and its one end has terminal head 20, and the other end is connected with the conversion line on surface-mounted integrated circuit, and this terminal head 20 can mate by the communication apparatus of required connection.Arrangements of electric connection 2 is built-in with a change-over circuit 22, change-over circuit 22 extend out the output circuit 30 of be set with arranged side by side, input circuit 32 and earth lead 34.Change-over circuit 22 is made up of electric capacity (c1, c2), impedance (R1, R2) and control handle (K1, K2), and wherein, K1 is the headset switch controlling signal of telecommunication output, and K2 is the microphone switch controlling signal of telecommunication input.In change-over circuit 22, electric capacity c1, impedance R1 and control handle K1 are in series, then are connected with the output circuit 30 of the signal of telecommunication；Electric capacity c2 and impedance R2 connects with control handle K2 after being in parallel, then is connected with the input circuit 32 of the signal of telecommunication.The power of the signal of telecommunication is controlled by electric capacity (c1, c2) and impedance (R1, R2), the transmission of each line electricity signal can be controlled by control handle K1, K2 respectively, make user optionally participate in or exit teleconference, and do not disturb the carrying out of teleconference.
Conversion line on surface-mounted integrated circuit is made up of some microphone input circuit M, earphone output circuit R and earth lead G, each bar input circuit M is also connected in parallel respectively between two, and is controlled the power of the signal of telecommunication by electric capacity (C1, C2 ... C7) and impedance (R1, R2 ... R7)；Equally, it is connected in parallel between two respectively between each bar output circuit R, and is controlled the power of the signal of telecommunication by electric capacity (C8, C9 ...
