摘要： A piezoelectric actuator 60 includes a piezoelectric element 10 expanding and contracting according to a state of an electric field, a pedestal 20, a vibration film 30, and a support member. In the vibration mode of the divided vibration occurring in the piezoelectric actuator in a high frequency band, one or more reinforcement members 50 are selectively disposed on an upper surface or a lower surface of the piezoelectric element 10, in a region where a node of divided vibration occurs. With such configurations, the vibration mode can be changed in the piezoelectric element 10. Therefore, in the frequency sound pressure level characteristics, the divided vibration causing hills or valleys (peaks or dips) can be effectively suppressed, thus enabling the achievement of flatness of frequency sound pressure level characteristics and of reproduction of excellent sound.

摘要： A viscoelastic body is interposed between a vibrating membrane vibrating in association with a piezoelectric vibrator composed of a piezoelectric element and a base and a support member supporting the vibrating membrane. The viscoelastic body attenuates vibration transmitted from the support member to the vibrating membrane and converts vibration of the vibrating membrane in the surface direction parallel to its main surfaces to vibration of the vibrating membrane in the direction nearly perpendicular to the surface direction. The vibrating membrane is annular with an opening at the center, and the base is joined to the vibrating membrane coaxially with opening.

摘要： A magnetic bubble memory device is disclosed in which a hardened film made of a heat-resisting highly-polymerized organic resin and having a predetermined thickness is employed for an insulating film interposed between a conductor pattern and a soft magnetic material pattern. In a conventional magnetic bubble memory device in which the above-mentioned insulating film is made of SiO.sub.2, an abrupt step is produced in the soft magnetic material pattern due to the existence of the conductor pattern beneath a portion of the soft magnetic material pattern, and the margin of bias magnetic field is thereby lowered. According to the present invention, the step is reduced and smoothed, and thus the lowering of the margin can be prevented.
