摘要： An ultrasonic transducer is described that comprises an oscillatory element (e.g., piezoelectric or electrostatic) having a frequency of oscillation in the ultrasonic region. The transducer includes a conical diaphragm connected at its apex to the center of the oscillatory element. The diaphragm has a rim which defines a concave opening and is responsive to an actuation of the oscillatory element to generate a plane wave in the direction of the concave opening. A faceplate having a small aperture abuts the rim of the conical diaphragm. The diaphragm is concentrically positioned with respect to the aperture and is bonded to the faceplate by a flexible adhesive. An induced plane wave is thereby diffracted by the aperturre and exits therefrom with a substantially omnidirectional beam pattern.

摘要： A parallel type piezoelectric bimorph vibrator is used for a piezoelectric buzzer or a piezoelectric loud-speaker, which is cemented at both ends of a conductive diaphragm together with piezoelectric elements, and is provided at part of the outer periphery of a diaphragm with a cutout, the outer peripheries of the piezoelectric elements facing the cutout. Electrodes outside both the piezoelectric elements are connected by a conductor at the position corresponding to the cutout, so that the existence of the cutout prevents the conductor from being brought into contact with the diaphragm.

摘要： A multifrequency piezoelectric sound-generating system is provided with a piezoelectric vibrator for generating audible sound at two or more resonance frequencies, an oscillator circuit connected to the piezoelectric vibrator for oscillating at one of the resonance frequencies, and a modulator circuit connected to the oscillator circuit for amplitude-modulating the oscillator circuit with a modulating frequency substantially equal or close to a frequency separation between the resonance frequencies to energize the piezoelectric vibrator with frequency-modulated waves to generate multifrequency audible sound.The modulator circuit may have a frequency divider that is operative in response to an oscillating frequency in the oscillator circuit for dividing or counting down the oscillating frequency into the modulating frequency to modulate the oscillator circuit therewith. The piezoelectric vibrator may include a diaphragm, a generally rectangular metal sheet which is smaller in size than the diaphragm and mounted on the diaphragm, and a sheet of a piezoelectric material mounted on the metal sheet.

摘要： An electronic timepiece including a piezoelectric type alarm buzzer wherein the caseback functions as the buzzer diaphragm is provided. The piezoelectric element is mounted on the caseback and a battery for driving the timepiece is mounted on the piezoelectric element with an electrical insulating member therebetween for preventing short-circuiting between the battery and piezoelectric element. In an exemplary embodiment, the electrical insulating member for mounting for holding the battery is mounted to the piezoelectric element at a peripheral portion in order not to effect adversely the sound level. Alternatively, when design considerations require the battery may be mounted in a more central portion of the piezoelectric element, an angular insulating member having a central opening is used so that the insulating member contacts the piezoelectric element at the periphery thereof.
