In view of this, the utility model provides a kind of anti-tampering conference telephone, and it can avoid meeting to be subject to external interference, improves the conference call quality.

[utility model content]

Main purpose of the present utility model provides a kind of anti-tampering conference telephone, and it can avoid meeting to be subject to external interference, improves the conference call quality.

For reaching above-mentioned purpose, a kind of anti-tampering conference telephone of the utility model comprises: a main station, one main frame loud speaker and a main frame microphone, be provided with an audio process in the described telephone crosstalk main frame, described audio process is connected with described main frame loud speaker and described main frame microphone, and described anti-tampering conference telephone is characterised in that further and comprises:

Several earphone jack, it is located in the described main station and with described audio process and is connected, and is provided with a detection switch in described each earphone jack; And

Several headsets, it has respectively a headset earphone and a headset microphone, described several headsets are connected with described audio process by described several earphone jack, when described each headset injected each earphone jack, described detection switch can be connected and connect described each headset and described audio process what described audio process and described main frame loud speaker and described main frame microphone were cut off in the insertion that detects headset afterwards.

Preferably, described main station further is provided with an amplifier, and described amplifier is between described audio process and described several earphone jack.

Compared with prior art, anti-tampering conference telephone of the present utility model is owing to being provided with the earphone jack that can supply headset to plug, therefore more noisy at the sensation conferencing environment, for avoiding meeting to be subject to external interference, the personnel of conference participation can insert headset the earphone jack of anti-tampering conference telephone of the present utility model, thereby can carry out meeting by the headset of wearing separately, improve the conference call quality.

[description of drawings]

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is a kind of anti-tampering conference telephone one preferred embodiment circuit catenation principle block schematic diagram of the utility model.

Fig. 2 is the anti-tampering conference telephone structural representation of the utility model shown in Figure 1.

[embodiment]

Fig. 1-2 is depicted as a kind of anti-tampering conference telephone one preferred embodiment of the utility model.Shown in Fig. 1-2, in the present embodiment, described anti-tampering conference telephone comprises a main station 10 and several headsets 20.

Be provided with an audio process 11, one main frame loud speakers 12 in the described main station 10, and a main frame microphone 13 and several earphone jack 14.Described audio process 11 is connected with described main frame loud speaker 12 and described main frame microphone 13, listen for the people with a part in a conference person that described main frame loud speaker 12 plays to described anti-tampering conference telephone 10 1 ends in order to will convert from the audio signal that described anti-tampering conference telephone 10 other ends receive certain form to, and become certain form to send to the other end of described anti-tampering conference telephone 10 from the speech conversion that described anti-tampering conference telephone 10 1 ends pick up described main frame microphone 13.Described several earphone jack 14 be connected with described audio process 11 and respectively in be provided with a detection switch 141.Unaffected in order to ensure the speech volume that each earphone jack 14 spreads out of, described main station 10 is further set up an amplifier 15 between described audio process 11 and described several earphone jack 14.

Enumerate in the present embodiment two headsets 20 and be example, described each headset 20 has respectively a headset earphone 21 and a headset microphone 22, described two headsets 20 are connected with described audio process 11 by described earphone jack 14, when described each headset 20 injected each earphone jack 14, the detection switch 141 in described each earphone jack 14 can be connected and connect described each headset 20 and described audio process 11 what described audio process 11 and described main frame loud speaker 12 and described main frame microphone 13 were cut off in the insertion that detects described headset 20 afterwards.

Generally, described anti-tampering conference telephone does not connect described each headset 20, when using, the participant by described anti-tampering conference telephone main frame loud speaker 12 and the participant of described main frame microphone 13 and the other end of described anti-tampering conference telephone carry out voice interface, and when the environment of feeling meeting is more noisy, in order to prevent from being subject to extraneous interference, the participant can insert described headset 20 in the earphone jack 14 of anti-tampering conference telephone of the present utility model, so that the detection switch 141 in described each earphone jack 14 is connected and connects described each headset 20 and described audio process 11 what described audio process 11 and described main frame loud speaker 12 and described main frame microphone 13 were cut off in the insertion that detects described headset 20 afterwards, thus, the participant can participate in a conference by headset 20 separately, has avoided extraneous interference.Owing between described audio process 11 and described two earphone jack 14, setting up described amplifier 15, therefore after the participant was with the above headset 20, the headset earphone 21 of each headset 20 still can provide voice with enough volumes to respectively with the participant of headset 20.
