Description

TECHNICAL FIELD The present invention relates to a sound insulation room structure for shielding sound.

(Prior Art) Conventionally, a sufficient sound insulation effect is required for an audio room, a piano room, etc., but a sound insulation room structure capable of sufficient sound insulation has not been developed yet.

(Problems to be Solved by the Invention) An object of the present invention is to solve the above-mentioned conventional problems and provide a sound insulation room structure capable of sufficient sound insulation.

(Means for Solving Problems) The present invention provides an airtight container-like outer body and an airtight container-like inner body having a space in the outer body to achieve the above object. A front plate that seals the partition space, an entrance / exit partition space that can enter and exit through a door in front of the inner body, an outer front plate that has a partition door that separates the entrance / exit partition space from the outside, and the partition space is evacuated. It proposes a sound insulation room structure consisting of a vacuum pump.

(Operation) Since the sound insulation chamber structure of the present invention has the space which can be evacuated by the vacuum pump, sufficient sound insulation can be achieved.

(Example) Hereinafter, a sound insulation room structure of the present invention will be described according to an example shown in the drawings.

1 and 2 show a soundproof room structure of the present invention. The soundproof room structure (1) has a container-shaped outer body (2) opened only on the front side.

The outer body (2) is formed into a container by air-tightly joining steel plates and the like.

Next, inside the outer body (2), the airtight container-like inner body (5) is separated by the space (3).
To be inserted.

The partition space (3) is sealed on the front by a front plate (7).

Further, in the illustrated embodiment, the inner body (5) is supported in a cantilever shape on the front plate (7) and fixed to the outer body (2) (however, the inner body (5)
A supplementary support material made of a sound insulating material that connects the inner body (5) to the outer body (2) may be used if necessary for the support strength of the).

Next, the inner body (5) is at the front door (8) at the entrance / exit space (9)
To be able to enter and leave.

The entrance / exit space (9) is partitioned from the outside by an outer front plate (10) having a door (11).

On the other hand, the space (3) can be evacuated by a vacuum pump (4).

In addition, the electrical wiring of the sound insulation room (6), ventilation piping, etc. are the entrance and exit space (9)
Shall be led to the outside.

The operation of the soundproof room structure of the present invention shown in the above embodiment will be described below.

That is, in order to use the sound insulation room (6), the user first drives the vacuum pump (4) to evacuate the partition space (3).

In this state, the user enters the sound insulation room (6) through the door (11) and the door (8) and uses it as an audio room, a piano room or the like.

Since the sound insulation room (6) is shielded from the outside in the vacuumed space (3), the sound inside the room is cut off in the space (3).

That is, in the vacuumed space (3), almost no sound is transmitted and the sound is insulated.

On the other hand, the sound insulation of the entrance / exit space (9) is performed by the conventionally known sound insulation structure, and therefore, the sound insulation of the front plate (7) is particularly important.

(Effects of the Invention) The embodiments of the sound insulation room structure of the present invention are as described above, and the effects are listed below.

(1) The sound insulation room structure of the present invention has the structure described in the claims, and in particular, since it has a partition space that can be evacuated by a vacuum pump, sufficient sound insulation is possible.

(2) The sound insulation room structure of the present invention has the same structure as above. Particularly, since there is an entrance / exit space in the front, sound leakage is extremely small even in the front.
