The air supply / exhaust terminal component as described above can be used as a component of a ventilation system in a building, a public facility, etc. because the air supply and exhaust points in the ventilation system can be branched in many directions by ducts. Widely adopted. However, since many things such as lighting fixtures, loudspeakers for guide broadcasting and fire protection devices have been installed on the ceiling in such places, the ceiling surface became more complicated and harmonious due to the installation of air supply and exhaust terminal parts. It also tends to be difficult to form an indoor atmosphere.

Since the air supply / exhaust terminal parts require a device for the ventilation as well as a duct piping space, the space above the ceiling is suitable as an installation place in order not to narrow the room. Ceiling is not always suitable. That is, most of the ceilings of buildings are continuous spaces, and if you ignore the acoustic effect of this space, the sound of the speaker attached to the ceiling of a particular room will echo in other rooms, and the sound itself will It will be of poor quality. Therefore, in actual construction, the speaker must be a speaker device with a speaker box, or a speaker box made of a sound absorbing material or the like must be formed on the ceiling and the speaker must be attached.

[0006] It is an object of the present invention to provide a supply / exhaust terminal component which does not compete with a speaker for a mounting location and which has a sufficiently satisfactory function as a speaker device and which provides a simple and harmonious indoor atmosphere. ..

[0007]

A supply / exhaust terminal component according to the present invention is mounted in a space such as a space above a ceiling, and one end thereof serves as an opening opening to the inside of the room and the other end serves as a connection port with a ventilation device or the like. A speaker is functionally attached to a decorative lid member, which is attached like a lid in the center of an opening of a tubular main body configured to be duct-connectable, toward the indoor side.

Another air supply / exhaust terminal component according to the present invention is one in which the speaker is attached to the center of the decorative lid member and the back of the speaker is wrapped with a sound absorbing member which also has an umbrella shape and serves as a ventilation guide. ..

[0009]

In the air supply / exhaust terminal parts according to the present invention,
The main body, which is connected to a ventilation device etc. by a duct and itself has an excellent acoustic effect, becomes a suitable speaker box for a speaker attached to a decorative lid member, and is used for BG, guide broadcasting, and other notification means. There is no need to install a speaker separately.

Further, in another air supply / exhaust terminal component according to the present invention, the sound absorbing member provided especially behind the decorative lid member improves the acoustic characteristics of the speaker, and at the same time, allows the flow of the air supply or exhaust air to flow therethrough. Smooth out.

The back surface of the speaker 5 is wrapped with the sound absorbing member 6.

In the air supply / exhaust terminal component having the above-described structure, the main body 1 is attached to the space above the ceiling, and the connection port 4 is connected to a ventilation device or the like by a duct to serve as a supply air blowing portion or an exhaust suction portion of the ventilation system. The makeup lid member 2 is attached to the opening of the main body 1 along the ceiling surface, and the gap 3 serves as an air supply outlet or an exhaust air inlet to supply fresh outside air into the room or suck in polluted room air. become. At this time, the umbrella-shaped sound absorbing member 6 guides and smoothes the flow of the airflow flowing in or out of the gap 3 and serves to reduce the sound of the airflow. The speaker 5 incorporated in the decorative lid member 2 is connected to an output system of an audio device or a broadcasting device,
It will work independently as the output means of the audio device and the broadcasting device. The speaker 5 is not exposed, and the back surface is covered with the sound absorbing member 6, and the main body 1 has an excellent structure in terms of acoustic effect which is less likely to resonate and has less reverberation by being connected by the duct. Since the speaker device that completes the installation of the member 2 becomes a suitable speaker box for the speaker 5, it is not necessary to separately install a speaker for BG, guide broadcasting, and other notification means, and the ceiling surface is disordered. It is possible to avoid an inconsistent state in which various functional parts are lined up.

[0015]

As is apparent from the above description of the embodiment, according to the present invention, one end is connected to a ventilation device or the like by a duct, and a cylinder having an excellent structure in terms of acoustic effect with less resonance and less reverberation. The main body becomes a suitable speaker box for the speaker attached to the decorative lid member, and it is not necessary to separately provide a speaker for BG, guide broadcasting, and other notification means, so that the speaker does not conflict with the installation location. It is possible to obtain a supply / exhaust terminal component that can realize a simple and harmonious indoor atmosphere that sufficiently functions as a speaker device.

Further, according to another air supply / exhaust terminal component of the present invention, the acoustic characteristics of the speaker are improved by the sound absorbing member provided especially behind the decorative lid member, and the airflow is smoothly distributed in the relevant portion. It also has the effect of reducing airflow noise.
