PIEZOELECTRIC VIBRATOR WITH ASYMMETRIC I-TYPE ELASTOMER AND PIEZOELECTRIC PANEL SPEAKER USING THE SAME

摘要

The present invention relates to a piezoelectric vibrator used in the piezoelectric speaker, in particular elastic material of an asymmetric I-shape relates to a panel provided with a speaker using the vibration characteristics, and this significantly improved the piezoelectric transducer. The piezoelectric transducer is attached to one surface of the piezoelectric actuator (piexoelectric actuator) for converting the electrical signal consists of an elastic material attached to the piezoelectric material and the electrodes are attached to both sides of the piezoelectric material to mechanical vibration, the piezoelectric actuator (piexoelectric actuator) a mechanical vibration generated by the piezoelectric actuator comprising an elastic body for vibration transmission for transmitting to the outside is, it has a piezoelectric actuator with the oscillation axis of the elastic body for the entire transmission direction I-shaped cross-sectional shape of the asymmetry. A piezoelectric vibrator according to the present invention has a simple structure, the manufacturing process can be simplified, can generate a high piezoelectric resonator, and by adjusting the asymmetry of I-shaped, and can adjust the wavelength having the maximum sound pressure, and the power consumption compared to the energy can greatly improve the efficiency of reduction of power consumption, it is possible to reduce the signal distortion caused by the reduction in size and noise of the product. Further, the piezoelectric vibrator according to the present invention can obtain a stereo sound effect in one of the panel when the speaker mounting two or more panels to a vibration.
