摘要： A piezoelectric electroacoustic transducer eliminates the need for the interconnection between main surface electrodes and internal electrodes, and is capable of constructing a bimorph diaphragm using a simple connection structure. The piezoelectric electroacoustic transducer includes a laminated body formed by laminating two or three piezoelectric ceramic layers, main surface electrodes each provided on the top and bottom main surfaces, and an internal electrode provided between any adjacent two piezoelectric ceramic layers. In the piezoelectric electroacoustic transducer, all ceramic layers are polarized in the same direction with respect to the thickness direction, and by applying an alternating voltage across the main surface electrodes and the internal electrode, the laminated body generates a bending vibration in its entirety.

摘要： A piezoelectric acoustic component includes a unimorph-type vibration body, a mounting substrate, and a cover. The vibration body includes a substantially rectangular piezoelectric plate and a substantially rectangular metallic plate bonded to the back side of the piezoelectric plate. Longitudinal opposite end portions of the vibration body are fixed onto the mounting substrate via respective support members. The metallic plate of the vibration body is fixedly connected to a first electrode located on the mounting substrate via one of the support members, whereas the electrode located on the front side of the piezoelectric plate is connected to a second electrode located on the mounting substrate via a conductive wire. A gap between the mounting substrate and each of lateral opposite end portions of the vibration body is charged with silicone rubber, thereby defining an acoustic space between the vibration body and the mounting substrate. A cover having a sound release hole formed therein is bonded onto the mounting substrate so as to cover the vibration body without contacting the same.

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 electroacoustic transducer includes a diaphragm including a substantially rectangular metal plate and a substantially rectangular piezoelectric plate having electrodes on an upper surface and a lower surface thereof, with one of the electrodes being connected to the metal plate. A support medium including retaining parts for retaining two shorter sides of the diaphragm is provided. The shorter sides of the diaphragm are fixed to the retaining parts by an adhesive having a Young's Modulus after curing that is between about 4.0×104 N/m2 and about 5.0×106 N/m2. Gaps between the two longer sides of the diaphragm and the support member are sealed by an elastic sealant. The diaphragm is arranged to undergo bending vibration in a longitudinal bending mode by applying a predetermined electrical signal between the metal plate and the opposing electrode provided on the piezoelectric plate.

摘要： A piezoelectric component has a substantially stronger connection between a substrate and a piezoelectric resonator and has improved electrical reliability. The piezoelectric resonator includes an insulating substrate having pattern electrodes disposed therein. A piezoelectric resonator capable of vibrating, for example in a longitudinal vibration mode is mounted on the substrate. A supporting member prepared separately as a pre-formed material member is bonded to the piezoelectric resonator at a nodal point of the resonator. A first flat surface of the supporting member is bonded to a vibrating electrode on the piezoelectric resonator by a first bonding and supporting material while a second flat surface of the supporting member is bonded to one of the pattern electrodes on the substrate by a second bonding and supporting material. The length of bonding between the piezoelectric resonator and the first bonding and supporting material along the longitudinal direction of the piezoelectric resonator is preferably set to about 25% or less of the overall length of the piezoelectric resonator. A central portion of another vibrating electrode of the piezoelectric resonator is connected to the other pattern electrode on the substrate by a conductor wire.

A series resonator includes a substantially rectangular piezoelectric plate vibrating in a length vibration mode and has vibrating electrodes located on a pair of opposite side edge surfaces of the substantially rectangular piezoelectric substrate. A parallel resonator including a substantially rectangular piezoelectric plate vibrating in a length vibration mode has vibrating electrodes located on the front and back major surfaces of the substantially rectangular piezoelectric substrate. The series and parallel resonator are mounted on the substrate in such a manner as to be spaced apart from each other. The vibrating electrodes of the series resonator are connected with the line electrodes, respectively, by using a conductive adhesive agent. One of the vibrating electrodes of the parallel resonator is connected to the vibrating electrode of the series resonator through a conductive adhesive agent. Further, the other of the vibrating electrodes of the parallel resonator is connected to the remaining line electrode through a metallic wire.
