And the silence system 1 by this Embodiment becomes a structure which performs control which increases / decreases the sound of the speaker in the karaoke room 2 by the opening / closing state of the door 21. FIG.

Hereinafter, the configuration of the silencing system 1 will be described more specifically.
As shown in FIG. 1, the karaoke room 2 includes a karaoke controller 10, a power amplifier 11, and a plurality of (two in this embodiment) speakers 12 (in the same manner as a well-known karaoke room used by a plurality of people). 12A and 12B) and an attenuator 13 and 13 corresponding to each speaker 12 are provided. That is, the karaoke controller 10 is connected to the speakers 12A and 12B via the power amplifier 11 and the attenuators 13 and 13 so that performance sound control and sound control are performed.
The karaoke controller 10 is also connected to video equipment such as a monitor (not shown) and lighting equipment, and can perform video control and lighting control together with sound, but detailed description thereof is omitted here.

  The silencing system 1 includes a door opening / closing detection means 3 for detecting the opening / closing of the door 21 of the karaoke room 2 and the karaoke room 2 when the door opening / closing detection means 3 detects the opening / closing signals (P1, P2) of the door 21. And a signal control device 4 (signal processing means) for controlling the sounds of the speakers 12A and 12B to have a predetermined volume.

  As shown in FIG. 1, specifically, the door opening / closing detection means 3 is provided on a detection sensor 31 provided on the room wall surface 22 of the karaoke room 2 and on the door 21, and the detection sensor 31 in a state where the door 21 is closed. And a detected portion 32 provided so as to be detectable. In the present embodiment, the detected portion 32 is a metal piece, and a proximity switch that detects metal or the like is used as the detection sensor 31. The detection sensor 31 is always in a state where the open / closed state of the door 21 is monitored. When the door 21 is in the closed state, the detected part 32 is detected and an ON signal P1 (closed signal) is sent to the signal control device 4. When the door 21 is in an open state, an OFF signal P2 (open signal) that does not detect the detected portion 32 is transmitted to the signal control device 4.

  The signal control device 4 is interposed between the power amplifier 11 and the attenuator 13 and increases or decreases the outputs of the speakers 12A and 12B via the attenuators 13 and 13 based on the open / close signal of the detection sensor 31 described above. It has become. Then, the signal control device 4 reduces or stops the sound of the speakers 12A and 12B when the OFF signal P2 of the detection sensor 31 described above is received, and the volume of the speakers 12A and 12B when the ON signal P1 is received. Control is performed so as to return to the original sound volume (volume before opening the door 21).

Next, an operation flow of the muffler system 1 in the karaoke room 2 for one person configured as described above will be described with reference to FIG.
As shown in FIGS. 1 and 2, when the door 21 is opened between the karaoke rooms 2 in the karaoke room, as shown by the two-dot chain line shown in FIG. 1, the detected part 32 on the door 21 side becomes the room wall surface 22 side. (Step S1), the OFF signal P2 is detected by the detection sensor 31 (step S2). Then, the signal control device 4 receives the OFF signal P2, controls the volume (output) of the speakers 12A and 12B (step S3), and reduces or stops the sound of the speakers 12A and 12B (step S4).

  Subsequent to step S4 described above, when the door 21 is closed in step S5, the ON signal P1 is detected by the detection sensor 31 (step S6). Then, the signal control device 4 receives the ON signal P1, the volume (output) of the speakers 12A and 12B is controlled (step S7), and the volume of the speakers 12A and 12B is the original volume (volume before opening the door 21). (Step S8).

  Thus, in this silencing system 1, since the sound of the speakers 12A, 12B can be automatically reduced or stopped when the door 21 of the karaoke room 2 is opened, the karaoke room is opened when the door 21 is opened. It is possible to eliminate the problem of sound leaking to the outside. Therefore, in the silencing system 1, karaoke for one person as in the present embodiment, in which karaoke can be interrupted by reducing or stopping the sound of the speakers 12A and 12B when the door 21 is opened and closed. It can be applied to room 2.

  In the silencing system for a karaoke room according to the above-described embodiment, the sound in the karaoke room 2 can be automatically reduced or stopped when the door 21 is opened. It is possible to eliminate problems such as discomfort to people outside of 2, and to improve the service to customers.

As mentioned above, although embodiment of the silencing system for karaoke rooms by this invention was described, this invention is not limited to said embodiment, In the range which does not deviate from the meaning, it can change suitably.
For example, in the present embodiment, a proximity switch is used as the detection sensor 31 of the door opening / closing detection means 3, and a metal piece is used as the detected portion 32. However, the present invention is not limited to such a configuration. Other forms are also possible. For example, a door opening / closing detection means by a combination of a reflective photoelectric switch (detection sensor) and a reflection plate (detected part) may be adopted. Alternatively, a contact type limit switch is used as a detection sensor, and the switch is brought into an ON state by bringing the switch into contact with the closed door 21. When the door 21 is opened, the door opening / closing detection means is configured to be in a non-contact state. You can also.
Furthermore, the attachment position of the detection sensor 31 and the detected part 32 of the present embodiment is not particularly limited, and can be set to any position according to the shape of the door.

  Furthermore, in this embodiment, when the ON signal P1 (close signal) when the door 21 is closed is detected by the detection sensor 31, the signal control device 4 receives the ON signal P1 and the volume of the speaker 12 ( Output) is controlled, and the volume of the speaker 12 that has been reduced or stopped when the door 21 is open is returned to the volume before the door 21 is opened, but when such a door 21 is closed. The structure which does not perform control of this may be sufficient. For example, it may be configured to manually set an arbitrary volume after an arbitrary time after the door 21 is closed.

In the present embodiment, the silencing system 1 is applied to the karaoke room 2 for one person. However, the present invention is not limited to the karaoke room for one person. Depending on the conditions, the silencing system 1 may be applied to a karaoke room used by a plurality of people.
The configuration of the karaoke facility, that is, the size and area of the karaoke room, the karaoke controller 10, the power amplifier 11, the speaker 12, and the attenuator 13 is not particularly limited and depends on the purpose of use. Can be set arbitrarily.
