摘要： A piezoelectric resonator having a miniature size and being fabricated at a low cost is used in a ladder-type filter that has a substrate, on the front and back surfaces of which line electrodes are provided. 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.

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： 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 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.
