Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a theater, and more particularly to a theater capable of varying reverberation time.

(Prior Art) The reverberation time in a room such as a theater or a hall (hereinafter referred to as a theater) is determined by the room volume and the sound absorption coefficient of a wall, a ceiling, a floor, or the like.

By the way, the reverberation time has an optimum value depending on the performance held at the theater. Therefore, conventionally, the reverberation time is adjusted by rotating the wall portion or taking out the sound absorbing material from the ceiling depending on the performance.

(Problems to be Solved by the Invention) The reverberation time can be calculated by a predetermined formula having a factor such as room volume, but the variable part cannot be large, so the rate of change in the reverberation time is not sufficient for the cost involved. At the same time, it is difficult to design the reverberation variable device itself, and it is often impossible to secure the performance at the time of design. Further, when a sound absorbing surface is provided on the wall, there is a problem that the effective reflecting surface is lost and the sound is deteriorated. This problem is particularly remarkable in the primary reflection. Further, when the sound absorbing material is projected on the ceiling, there is a problem that it affects the lighting and the like.

Therefore, it is an object of the present invention to provide a theater capable of adjusting the reverberation time in a preferable state without causing new problems, unlike the above-mentioned conventional technique.

(Means for Solving the Problem) According to the present invention, the passenger seats in the theater are provided in the floating cloud type hierarchy, and the passenger seats are provided behind the passenger seats in these hierarchy states through the floors of the floating cloud type seats. The above-mentioned object is achieved by providing a space for adjusting the reverberation time which communicates with the front and providing a movable partition wall for adjusting the volume of the theater room in this space.

(Operation) In the theater of the present invention, since the audience seats are provided in a floating cloud type hierarchy, the sound from the stage side in front of the theater propagates to the reverberation time adjusting space behind it through the floating cloud type floors. , If the movable partition wall provided in the space is moved according to the item, the room volume of the theater is adjusted, the reverberation time can be set to a preferable value according to the item, there are many accommodating personnel, and the entire audience seats are close to the stage. It will be visually good.

(Embodiment) Hereinafter, a theater according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a front-rear sectional view of a theater according to an embodiment of the present invention, in which reference numeral 1 indicates a theater room.

This theater room 1 has a stage part 2 which is the front part thereof,
It consists of a passenger seat part 3 which is the rear part. A stage 4 is installed in the stage part 2 and a seating part 3
The first-floor seats 5 are located in the rear of the stage 4 almost following the stage 4. The first-floor passenger seats 5 are arranged only in a portion approximately 2/3 in front of the passenger seat portion 3. Also, 2nd floor seats 6
And the third-floor passenger seat 7 is located above the rear part of the first-floor passenger seat 5,
It is a so-called floating cloud type and is installed in a hierarchy.

A space 8 for adjusting reverberation time is communicated with the rear of the first-floor passenger seats 5, the second-floor passenger seats 6 and the third-floor passenger seats 7. That is, approximately 1/3 of the back of the passenger seat portion 3 in the theater room 1 is formed as a space.

In front of the reverberation time adjusting space 8, the space 8 and
A sound insulation partition wall 9 that separates from the space on the front side is detachably provided.

In the above structure, as shown in FIG. 1, if the sound insulation partition wall 9 is installed behind the passenger seats 5, 6, and 7,
The actual room volume is relatively small, and the reverberation time is also
It will be about 1.0 second (at 500Hz), which is suitable for theater and lectures. On the other hand, as shown in FIG. 2, if the sound insulation partition wall 9 is removed, the substantial room volume becomes relatively large, and the reverberation time becomes about 2.0 to 2.5 seconds (at 500 Hz), so that the classical concert is performed. It is suitable for concerts. If the mounting position of the sound insulation partition wall 9 can be set variously,
The chamber volume can be changed continuously, and as a result, the reverberation time can also be changed continuously.
A complete multi-purpose hall can be realized.

Further, in the audience structure of the theater, all the spectators are close to the stage, so that the performers can be seen well and the primary reflected sound and sound pressure level from the side can be secured. We can provide sufficient services in both aspects.
Furthermore, since the passenger seats are arranged in a hierarchical manner, it is possible to secure sufficient accommodation personnel.

The approach to the passenger seats can be made by a bridge from the side or the rear.

As described above, with reference to FIGS. 1 and 2, the reverberation time adjusting space 8 is provided at the rear of the room space.
As shown in FIG. 3, a second reverberation time adjusting space 10 is further arranged in the upper part of the room space, and the second reverberation time adjusting space 10 is arranged in the second sound insulation partition wall.
The reverberation time may be adjusted by opening and closing at 11.

(Effects of the Invention) In the theater of the present invention, a part of the audience seats is provided in a floating cloud type hierarchy, and a reverberation time adjusting space communicating with the audience seats in front of the audience seats is provided behind the audience space. Since a movable partition wall is provided to adjust the volume of the theater room, the reverberation time can be changed in a suitable state according to the performance, and since the audience seats are arranged in a floating cloud type hierarchy, Can be sufficiently secured, all of the audience can see the performers well near the stage, and the primary reflected sound and sound pressure level are secured, so that there is an effect that a theater or the like can be performed in a good condition in both audiovisual sense.
