An inner wall parallel to the outer wall of the housing is provided on the inner side of one of the housings with a predetermined gap from the outer wall, and the operation button is exposed outside the mating portion of the two housings. An operating head portion and a body portion that is continuous with the operating head portion are provided, and in the body portion, an engaging portion that engages with an operating shaft of the device located inside the inner wall, and the operation button A first guide plate adjacent to the inner surface of the outer wall in a state of being attached to the housing, and parallel to and in front of the first guide plate. A second guide plate adjacent to the inner surface of the inner wall is provided, and a locking projection is provided at the tip of any one of these two guide plates, and the inner surface of the first guide plate is An elastic member for urging the outer surface of the inner wall in a state where the operation button is attached to the housing is provided, and the first guide plate and the elastic member are inserted into a gap between the outer wall and the inner wall, When the inner wall is inserted between the elastic member and the second guide plate, and the engaging portion is engaged with the operation shaft to position the head portion in the recess, the operation button is operated by the locking protrusion. Locked to either the outer wall or the inner wall, and by pressing the head of the operation button,
The operation part is attached to the mating part of the first housing and the second housing so as to be able to retract into the housing by energizing the elastic member, and the mating part of the split housing. Mounting structure for operating members. 4. A lower housing attached to a building material such as a wall surface and an upper housing superposed on the lower housing, and inside the housing composed of the upper housing and the lower housing,
A speaker for sounding, a drive circuit for the speaker, terminals for transmitting and receiving signals to and from the drive circuit, and a control unit for the drive circuit for controlling tone color adjustment and volume adjustment of the speaker are provided. The control unit is located at a lower portion of the lower housing in a state of being attached to the building material, and the operation buttons of a push-type operating device provided in the control unit are provided on the lower surfaces of the upper housing and the lower housing. In the sounding device provided so as to be exposed at the mating portion on the side, the mating portion of the split housing according to claim 3, as a structure for attaching the operation button to the mating portion of the upper housing and the lower housing.
