摘要： A piezoelectric electroacoustic transducer includes a piezoelectric diaphragm having a substantially rectangular shape which vibrates in the thickness direction when an alternating current is applied between electrodes of the piezoelectric diaphragm, a housing which stores the piezoelectric diaphragm, and a pair of terminals formed in the housing by insert molding. One end of each terminal is inserted inside the housing and includes a body portion fixed to the housing and wing portions which extend from both sides of the body portion toward the corners of the housing. The wing portions are not fixed to the housing, and stress-relieving portions are disposed between the body portion and the wing portions so that the wing portions are able to move toward the inside of the housing. Each electrode of the piezoelectric diaphragm is connected to at least one of the wing portions of the terminals by a conductive adhesive.

摘要： A piezoelectric electroacoustic transducer includes a piezoelectric sounding body in which bending vibration is generated by applying an alternating signal between two electrodes, a case housing the piezoelectric sounding body, and a pair of terminals insert-molded in the case. In the piezoelectric electroacoustic transducer, internal connection portions of the pair of terminals are exposed on the inside surface of the side wall portion of the case so as to extend in a direction that is substantially perpendicular relative to the piezoelectric sounding body, and the internal connection portions of the terminals are electrically connected to the electrodes of the piezoelectric sounding body by using conductive adhesive. The internal connection portions of the terminals do not largely extend inside the case and accordingly, the dimensional difference between the case and the piezoelectric sounding body is minimized.

摘要： An insert terminal containing case includes a bottom wall, four side walls, and an opening at the upper portion, wherein a terminal made of a metal plate is vertically fixed to at least one of the four side walls by insert molding. A groove is vertically arranged at the outer side surface of the side wall fixing the terminal, the groove extending downward, the outer side surface of the terminal is partially exposed at the groove, and the inner side surface opposite the outer side surface of the terminal exposed at the groove is partially exposed at the inner side surface of the side wall. Therefore, when the terminal is provided in the case by insert molding, molding can be performed only using upper and lower dies. Furthermore, the terminal can be reliably exposed at the inner surface of the side wall. The insert terminal containing case has the minimum difference between the opening dimension of the case and the dimension of a piezoelectric diaphragm and is molded without using a sliding die.

An internal electrode is disposed in an interface between adjacent piezoelectric ceramic layers. The upper and lower principal surfaces of the multilayer ceramic body are substantially entirely covered with a resin layer. A first cutout is formed in a side-edge portion, along the first side surface electrode, of the upper resin layer such that the upper principal-surface electrode is partially exposed in the first cutout. A second cutout is formed in a side-edge portion, along the first side surface electrode, of the lower resin layer such that the lower principal-surface electrode is partially exposed in the second cutout. The locations of the first and second cutouts formed in the upper and lower resin layers, respectively, are selected such that they do not oppose each other.

The base member is polarized in different directions at both sides of each electrode. Electrodes are alternately covered by a first insulating film and a second insulating film, respectively, at both sides of a groove formed in the base member. The first insulating film covers electrodes which are not covered by the second insulating film, and vice versa. External electrodes are formed at both sides of the groove on the base member and the internal electrodes are connected to the external electrodes. A support member made from an electrically conductive material is provided at the approximate centers of the external electrodes.
