ABSTRACT:
There is a need for being able to excellently audiovisually receive contents without disordering a room atmosphere. An audiovisual room1is provided with one wall including an inner wall2and an outer wall3. Part or all of the inner wall2forms a rear-projection screen6C or a diaphragm (speaker unit)6A. Equipment such as a projector10and an amplifier is placed in a space between the inner wall2and the outer wall3. The space is large enough for a person to enter. Accordingly, a serviceperson etc. can enter the space to easily do works such as maintaining the equipment. The equipment such as the projector is not placed in the audiovisual room1, making it possible to audiovisually receive contents without disordering a room atmosphere.
