摘要： A piezoelectric resonator uses a radial flexural mode vibration. In the piezoelectric resonator, an even number of at least four electrode layers and an odd number of at least three piezoelectric layers are alternately stacked. Among the three piezoelectric layers, at least two piezoelectric layers are polarized in a thickness direction. The four electrode layers are connected to one another so that, in at least one piezoelectric layer among the three piezoelectric layers, an electric field is generated in a direction that is identical to the polarization direction of the at least one piezoelectric layer, and in at least another piezoelectric layer among the three piezoelectric layers, an electric field is generated in a direction that is opposite to the polarization direction of the at least another piezoelectric layer. Among the three piezoelectric layers, at least one piezoelectric layer has a thickness that is different from each of the thicknesses of the other piezoelectric layers.

摘要： The invention aims at modifying SPUDT-type surface acoustic wave filters in such a way that the wideband filter can be produced with lower insertion loss and a small form factor without substantially enlarging layout. According to the invention, this is achieved by combining the following characteristics: a) the totality of fingers (231-233; 331-333) of each transducer (2; 3) forms a tapering structure and b) the widths and the positions of the fingers are chosen in such a way that the waves reflected on the fingers (231-233; 331-333) together with the waves regenerated by the corresponding source and load resistance (8; 9) result in an lengthening of the impulse response of the filter, which reduces form factor and/or bandwidth. The invention can be used in surface acoustic wave-based components such as wideband bandpass filters and delay lines.

摘要： Various piezoelectric transducers are provided. In one form, a polymer film or thin ceramic piezoelectric transducer is formed of various piezoelectric (active) and dielectric (inactive) layers in which the piezoelectric effect may be attenuated locally at any given point on the surface of the transducer, by use of printed circuit patterns, preferably made by photolithography. This provides a practical realization of a distributed piezoelectric transducer with a bi-dimensional polarization profile that varies smoothly over the surface of the piezoelectric structure. Flexibility of the fabrication procedure provides a way to optimize the design of a distributed piezoelectric transducer for applications such as active vibration control. In another form, a segmented piezoelectric transducer includes a set of active elements such as piezofilms, electronics and flexible printed circuits and connected with external electronic circuitry. The segmented piezoelectric transducer uses a modulation scheme to combine the individual sensor outputs. Modal coordinates may be extracted from a test structure on which the segmented piezoelectric transducer is attached. As well, it is possible to use a distributed piezoelectric transducer to actuate a structure by using a time-varying polarization profile.

摘要： Piezoelectric transformers have a number of favorable characteristics over traditional electromagnetic tranformers. However, the construction of piezoelectric transformers tends to be complicated, which may result in increasing manufacturing cost. Furthermore, such complex constructions may raise difficulties in the miniaturization of such devices. A ring-shaped piezoelectric transformer is developed in this invention for low voltage applications. One surface of the transformer is covered by two disc or ring-shaped electrodes separated by a ring-shaped separating segment, and the regions covered by the disc or ring-shaped electrodes served as the input and output parts of the transformer. This transformer may be fabricated relatively easily due to its simple structure. Furthermore, its size and thickness may be reduced relatively easily without increasing the difficulty of the fabricating process. The transformer may be used separately or in parallel.

摘要： A piezoelectric electro-acoustic transducer is constructed such that adherence of a piezoelectric diaphragm to a casing is easily performed, a sufficient supporting strength is achieved, and the piezoelectric diaphragm is supported while hindrance of vibration thereof is minimized. This piezoelectric electro-acoustic transducer includes a piezoelectric diaphragm constructed by adhering a piezoelectric ceramic plate having front and back surfaces including electrodes, onto a metallic plate, and a case in which the piezoelectric diaphragm is accommodated by fixing the peripheral portion thereof with an elastic adhesive. Support portions for supporting the peripheral portion of the piezoelectric diaphragm are provided in the case, and a supporting surface having an arcuate cross-section is provided on the supporting portions so that a center of curvature of the supporting surface is positioned near a lower surface of the peripheral portion of the piezoelectric diaphragm.
