A configuration that can be selectively switched to the monitor mode.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air monitor for a conference audio system installed in a conference room, and more particularly to an air monitor for a conference audio system suitable for accurately recognizing the loudness of a speaker's voice.

[0002]

[Prior art]

 As shown in FIG. 2, a device of this type is conventionally equipped with an air monitor microphone 1 provided on a ceiling, for example, in a conference room separately from a conference microphone arranged in the vicinity of a speaker, and monitors as a connection line. The monitor unit 2 connected by the line 63 listened to the loudness of the voice of the speaker.

On the other hand, conference microphones 31, 32, and 33, which are microphones that can be used by a plurality of speakers, are arranged in the vicinity of the speakers, and are controlled by the microphone control unit 5 via a control line 62. Of the plurality of microphones, for example, the microphone 31 is activated to collect the voice of the speaker using the microphone, and the output is input to the amplifier 4 via the audio main line 61, and the output is used as a loudspeaker. All the speakers 71, 72 and 73 are output to give a loud voice to the audience.

[0004]

[Problems to be solved by the device]

 As described above, in the conventional sound system, since the air monitoring microphone is placed on the ceiling, wall, or the like, which is far away from the position of the listener, the volume of the actual loud sound reaching the ears of the listener is increased. And I could not hear the sound quality.

[0005]

[Means for Solving the Problems]

 The present invention aims to solve the above-mentioned problems of the prior art, and in order to achieve the purpose, under the control of the microphone control unit, the microphone output switching unit connected to the conference microphone is expanded. It is characterized by a configuration that can be selectively switched between the mode and the monitor mode.

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. In FIG. 1, members that are the same as or equivalent to the members described in FIG. 2 are given the same reference numerals, and detailed description thereof is omitted.

Microphone output switching units 81, 82 and 83 are connected to the conference microphones 31, 32 and 33, respectively, and the microphone output switching units 81, 82 and 83 are connected to the amplifier 4 by the voice main line 61 and also to the monitor line. It is connected to the monitor unit 2 by 63. On the other hand, the microphone control section 5 is connected to the respective microphone output switching sections 81, 82 and 83 via the control line 62.

In such a configuration, the microphone control section 5 can switch any of the microphone output switching sections 81, 82 and 83 via the control line 62 to the loudspeaker mode or the monitor mode. Therefore, for example, assuming that only the microphone 32 is placed near the seat of the audience and not near the speaker, the microphone 32 is used as the monitor mode instead of the loudspeaking mode. In this case, the output of the microphone output switching unit 82 is transmitted to the monitor unit 2 via the monitor line 63, and the loud state (volume and sound quality) of the vicinity of the seat of the audience is heard. The outputs of the microphone output switching units 81 and 83 connected to the conference microphones 31 and 33 are adjusted according to the result of the hearing. If the microphone 32 is also placed near the speaker like other microphones, the microphone output switching section 82 is switched to the loud mode under the control of the microphone control section 5, and its output is It is transmitted to the speakers 71, 72, and 73 via the amplifier 4 via the audio main line 61.

[0009]

[Effect of device]

 As described above, according to the present invention, the microphone output switching unit is provided to select and switch whether the conference microphone is used as the speaker microphone or the air monitoring microphone arranged near the audience seat. As a result, the microphone can be selectively used as an air monitoring microphone, so that the volume and sound quality of the loud voice actually heard by the audience can be accurately heard.
