According to the present invention, there is provided a two-way communication assistance device comprising: a plug connected to an earphone jack of a portable telephone or a PHS; a microphone device having an acoustic / electric conversion circuit connected to the plug; Mobile phone, PH equipped with an earphone device having an electric / acoustic conversion circuit
The microphone is characterized in that a switch mechanism for opening and closing the circuit is provided in the acoustic-electric conversion circuit of the microphone device, wherein the switch mechanism is arranged to be capable of transmitting and receiving signals.

[0006] Then, the earphone device always operates,
Only when the switch of the microphone device is operated in connection, the auxiliary device can perform two-way communication. Further, the microphone device has a configuration in which a muting mechanism is provided to attenuate a cutting sound generated when a circuit is cut.

[0007]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is an overall view of a two-way communication assistance device having an earphone device and a microphone device according to the present invention, FIG. 2 is an enlarged view of a switch portion, FIG. 3 is a basic circuit diagram of the device, and FIG. FIG. 5 and FIG. 5 are explanatory diagrams showing the state of the conference.

[0008] According to the flow of the failure support shown in FIG.
Sent to. The support unit 20 arranges necessary parts inferred from the given failure information. Then, the necessary parts are transported to the failure site 10 by transport means R such as a truck. From the arrival of the support unit 20 of the failure information, arrange, arrangements have been parts of the parts to the time the time T ₁ until arriving at the failure site 10. On the other hand, upon receiving the failure information, the support unit 20 immediately transmits the failure information to the factory 30.

The support unit 20 analyzes the received failure information, and makes a decision 3 on the resulting recovery policy.
5 is transmitted (instructed) to the failure site 10. At this time, the total time of the time T ₂ required for the analysis and the countermeasure meeting at the support unit 20 and the transmission time T ₂ of the decision-making item at the failure site 10 reaches the failure site 10 at the latest. Time T ₁ (time T ₂ + time T ₃ = time T ₁ ). During this time, the telephone connecting the failure site 10, the support unit 20, and the factory 30 is in the call mode. In the support unit 20, the transmission / reception information from the failure occurrence site 10 is a mobile phone,
The configuration is such that a plurality of participants can receive by PHS or the like.

The situation of the failure support conference will be described with reference to FIG. This meeting includes multiple meeting members P ₁ , P ₂ ,
P _3, P ₄ ··· Pn to participate. Each participant P is equipped with the two-way communication assistance device 100 according to the present invention. The two-way communication assistance device 100 is a mobile phone or a plug 110 for connecting to an earphone jack 220 of the PHS 200,
It has an earphone device 120 having an acoustic conversion circuit and a microphone device 130 having an acoustic-electric conversion circuit. Further, the plug 110 and the earphone device 120,
A switch 150 is provided on a cord 140 connecting the microphone device 130. The switch 150 is provided in the middle of the acoustic-electric conversion circuit connected to the microphone device 130. Then, the input sound is transmitted (ON) and cut off (O) when the switch 150 is turned ON and OFF.
FF). For example, as shown in FIG. 2, the transmission of the sound is interrupted (OFF) by moving the operation button 155 in the direction of the arrow a, and the sound is transmitted (ON) by moving the operation button 155 in the direction of the arrow b. ).

[0011] The two-way communication auxiliary device 1 which operates as described above.
00 will be described with reference to a circuit diagram shown in FIG. The earphone device 120 can always receive when the plug 110 is connected to the mobile phone in the call mode or the earphone jack 220 of the PHS 200. In the microphone device 130, a switch 150 mechanism is provided on the way of the acoustic-electric conversion circuit 135. When the switch 150 is turned off, the sound input to the microphone device 130 is cut off. Then, when the switch 150 is turned on,
Only the person who uses the two-way communication assisting device 100 whose switch 150 is turned on can talk. Further, the muting mechanism 17 is provided in the course of the OFF circuit of the switch 150.
0 and the switch 150 of the microphone device 130
The cutting sound (noise) generated when the sound is cut off is attenuated to zero or a low level.

Here, assuming that the first speaker of the obstacle support conference, for example, the speaker P _1, is the switch 150 of the microphone 130 of the two-way communication assistance device 100 of the first speaker P _1.
Is ON. Members P ₂ , P ₃ , P attending other meetings
₄ ... Monitor with the switch 150 of the microphone 130 of the microphone device 100 with earphones of Pn set to OFF. When the speech of the first speaker P ₁ ends and the speaker becomes the second speaker P ₄ , the switch 150 of the microphone device 130 of the two-way communication assistance device 100 of the speaker P ₁ is turned off. was monitored as, ON the microphone device 130 for two-way communication assisting apparatus 100 of the speaker P ₄
As to say. The content of the remark is heard by the earphone device 120 of the two-way communication auxiliary device 100 provided by each user. Also,
At the time of disability support, the conductor of the support unit 20 and the fault occurrence site 10
Of the two-way communication assistance device 100 switch 150
To ON to participate in the conference.

As described above, in a conference in which a large number of people participate, the speech of only the speaker can be heard by the participants, and the speech (voice) of each participating person overlaps with the voice of the speaker, making it difficult to hear. There is no such scandal, the meeting time is shortened, and an urgent countermeasure policy and decision-making can be achieved in an emergency meeting such as when a failure occurs.

[0014]

According to the two-way communication assistance device of the present invention,
The progress of the meeting can be carried out smoothly, the meeting time can be shortened, and the policy and decision-making for prompt measures at the meeting can be achieved.
