DESCRIPTION JP2006138149
The present invention provides an acoustic installation capable of providing sound to both
adjacent room spaces without requiring an installation area of a speaker. A vibration generator
(10) is mounted in the vicinity of upper and lower end portions of a plate-like member (11)
constituting a door (D) disposed between a dressing room (X) and a bathroom (Y). The plate-like
member 11 can be functioned as a diaphragm to make the door D an acoustic device. It is
possible to provide sound equipment without separately installing a speaker, and the space for
effectively using the room can be expanded by the amount of omission of the speaker. Since
sound is generated from both sides of the door D and provided equally to the dressing room X
and the bathroom Y, the same sound can be experienced regardless of which room they are in.
Even if a person listening to music in the dressing room X moves to the bathroom Y, he can
continue to listen to the same music. In addition, when there are people in the dressing room X
and the bathroom Y, both can experience the same sound at the same time, so it is possible to
share topics and share information. [Selected figure] Figure 2
