    • A ladder filter has a piezoelectric resonator having reduced spurious vibrations and having a wider range of selection of the difference .DELTA.F between the resonant frequency and the antiresonant frequency, and has a substantially reduced size. 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.

    • 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 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.
