摘要： A piezoelectric type electric acoustic converter achieves large improvement in shatter resistance strength, increased operating efficiency and reduced size, and includes piezoelectric ceramic layers which are laminated to form a laminate. Main surface electrodes are disposed on the front and back main surfaces of the laminate, and an internal electrode is disposed between respective ceramic layers. A side electrode which connects the main surface electrodes, and a side electrode which is conducted to the internal electrode are formed on the side surface of the laminate. All the ceramic layers are polarized in the same direction, and by applying an alternating signal between the main surface electrodes and the internal electrode, bending vibration of the laminate occurs. The front and back surfaces of the laminate is almost entirely covered with resin-layers.

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 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.

The ladder filter includes an insulating substrate on which four pattern electrodes are provided. Four lands are respectively formed as portions of the four pattern electrodes. Another land is formed as a portion of the second pattern electrode. External electrodes of four piezoelectric resonators adapted to vibrate in a longitudinal vibration mode and capable of being mounted in a surface mount manner are connected to the land of the pattern electrodes by supporting members made of an electroconductive material. The four piezoelectric resonators are arranged in a row in the order of a first series resonator, a first parallel resonator, a second parallel resonator and a second series resonator.
