Abstract: A sound generator includes a sound generating body that generates sound, and a housing that houses the sound generating body. The housing includes a base having a base outer cylindrical portion and a partition wall, which is joined with a sound generating body, provided inside the base outer cylindrical portion, a cover that covers an opening on a front side of the base outer cylindrical portion, and a case that covers an opening on a rear side of the base outer cylindrical portion. The case includes a case rear portion arranged to face the opening of the base outer cylindrical portion, and a case width adjustment portion provided in an extending manner from the case rear portion. The case is joined to the base outer cylindrical portion at an end of the case width adjustment portion.

Abstract: A sound generator that generates sound by vibrating a diaphragm includes: a housing including a first space opened to the atmosphere by a sound emission hole and a second space separated from the first space by the diaphragm; and a shield plate disposed in the first space to face the diaphragm while being separated from the diaphragm. When the diaphragm is displaced toward the first space by a pressure difference between the first space and the second space, the diaphragm comes in contact with the shield plate to limit deformation of the diaphragm.

Abstract: In a sound generating device, a connection terminal made of a metal plate material electrically connected to an external equipment has a groove portion in a portion protruding inward of a base. A terminal fitting made of a metal plate material and electrically connected to the sounding body includes a terminal fitting main body that is mechanically joined to the sounding body, and a protrusion plate portion that extends from the terminal fitting main body portion and is press-fitted to the groove portion. The protrusion plate portion press-fitted to the groove portion of the connection terminal is provided integrally with the terminal fitting.

Abstract: A refrigerator cabinet basically comprises the body of cabinet, an outer box, an inner box and a heat insulating layer filled in a space formed between the boxes, characterized in that the outer box comprises a top wall and both side walls formed by bending one steel sheet previously coated with paint and further flanges reinforced by a reinforcing member without calking and rivetting, the reinforcing member being engaged with and supported by the groove formed in the flange. Since the reinforcing member roughly L-shaped can be installed by inserting work thereof, it offers excellent workability. In addition, because the reinforcing member is arranged tightly along the inside surface of the groove, it will not interfere with the operation of inserting the high temperature cooling medium pipe of the refrigerating cycle into groove and offer excellent operability.
