SOUND-REPRODUCING APPARATUS, LIGHTING APPARATUS, AND SUSPENDED OPENING AND CLOSING APPARATUS
First Claim
1. A sound-reproducing apparatus, comprising:
- plural coupling portions disposed at positions corresponding to vertices of an assumed first regular tetrahedron and second regular tetrahedron in a duality relation with each other;
plural rods connecting adjacent coupling portions to each other among said plural coupling portions;
plural shell portions joined to said plural rods;
an actuator disposed outside one coupling portion selected from said plural coupling portions with respect to a center of said first regular tetrahedron or a center of said second regular tetrahedron, said actuator being connected with said one coupling portion; and
first, second, and third speakers disposed or, of the four coupling portions disposed at positions corresponding to the vertices of the one of said first and second regular tetrahedra including said one coupling portion, three coupling portions excluding said one coupling portion.

Abstract
A sound-reproducing apparatus includes plural coupling portions, plural rods, plural shell portions, an actuator, and first, second, and third speakers. The coupling portions are disposed at positions corresponding to vertices of an assumed first regular tetrahedron and second regular tetrahedron in a duality relation. The rods connect adjacent coupling portions with each other among the coupling portions. The shell portions are joined to the rods. The actuator is disposed outside one coupling portion selected from the coupling portions with respect to a center of the first regular tetrahedron or second regular tetrahedron, and the actuator is connected with the one coupling portion. The first, second, and third speakers are disposed on, of the four coupling portions disposed at positions corresponding to the vertices of the one of the first and second regular tetrahedra including the one coupling portion, three coupling portions excluding the one coupling portion.

14. A suspended opening and closing apparatus, comprising:
-
plural coupling portions disposed at positions corresponding to vertices of an assumed first regular tetrahedron and second regular tetrahedron in a duality relation with each other, said first regular tetrahedron having a top portion thereof on a upper side in a vertical direction; plural rods connecting adjacent coupling portions to each other among said plural coupling portions; and an actuator disposed above one of said plural coupling portions disposed at a position corresponding to said top portion of said first regular tetrahedron, said actuator being connected with said one coupling portion.

15. A suspended opening and closing apparatus having a first state and a second state, the first state and the second state being changed to each other by an operation of an actuator disposed above,
wherein plural members belonging to a first group are disposed so as to correspond to vertices of a first regular tetrahedron, and plural members belonging to a second group are disposed so as to correspond to vertices of a second regular tetrahedron, and said first regular tetrahedron and said second regular tetrahedron are in a duality relation with each other in one of the first state and the second state.
