Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an acoustic reflector.

(Prior Art) Conventionally, when performing in an acoustic studio, the sound of the performance was reflected and absorbed by the walls, or reflected and absorbed by the ceiling.

(Problems to be Solved by the Invention) When a performance is performed only in the center of the studio, all the sound of the performance is reflected and absorbed by the ceiling surface because there are no walls near the periphery that serve as reflective surfaces. For this reason, it has not been possible to record the performance sound with excellent sound quality.

An object of the present invention is to enable, for example, recording with a simple configuration and excellent sound quality.

(Means for Solving the Problems) The present invention is suspended from the ceiling of an acoustic room by a hanging means so as to be able to rise and fall, has a sound reflecting surface formed on the lower surface, and has a light source for indoor lighting. This is what we have in place.

(Function) When performing only in the center of the acoustic room of a studio, by lowering the acoustic reflector to a predetermined position, the sound is reflected on the sound reflecting surface of the reflector.

(Example) An embodiment of the present invention will be described below.

In FIG. 1, an acoustic reflector 3 is suspended by a wire 4 from a ceiling 2 of an acoustic room of an acoustic studio. The lower end of this wire is attached to the hook 5 (the second
11), and the upper end side can be rolled up by a driving means 6 fixed on the back side of the ceiling part 2. The acoustic reflector 3 can be moved up and down by the operation of the drive means 6. This acoustic reflector has a planar circular shape as shown in FIGS. 2 and 3, and its lower surface is covered with a downwardly curved transparent shielding plate 7, and this a'M plate constitutes a sound reflecting surface. . A stepped ring portion 7a is formed at the center of the shielding plate 7. The ring portion 7a is a lattice in which bars are arranged radially. Illumination lights 9 are attached to a support frame 8 built into the acoustic reflector 3, and the illumination lights 1- are arranged in three layers at equal intervals in the circumferential direction around the axis of the reflector. It is.

Corresponding to the ring portion 7a of the shielding plate 7, the spotlight 1-
10° 108 and speakers 11 are arranged alternately in the circumferential direction. Further, bowl-shaped storage units 12 are mounted on the upper frame 8a of the acoustic reflector 3 at equal intervals around the axis of the reflector. At the inner bottom of each storage capacity, there is a decorative chain 13 hanging from the ceiling 2 (the part shown by the dotted line in Figures 1 and 2).
The bottom end of is the stop. The volume of each storage volume 12 is sufficient to store the chain 13 in a folded state.

Next, how to use it will be explained.

Normally, the acoustic reflector 3 is set at a position close to the ceiling 2, as shown by the solid line in FIG. 1, and is used as a lighting fixture.

When performing in the center of the acoustic room 1, the driving means 6
is activated, the acoustic repellent body 3 is lowered by the wire 4 to the position indicated by the chain line in FIG.

Normally, the acoustic reflector 3 is located close to the ceiling part 2 by winding up the wire 4, but at this time the decorative chain 13 is stored within the storage capacity 12 and is not visible from the outside.

(Effects of the Invention) According to the present invention, a reflecting surface can be formed in a necessary part by applying it as necessary with a simple configuration, it can provide excellent sound quality, and it can be advantageously used as illumination.
