PURPOSE: A ceramic oscillator is provided, which has a small size in comparison with a conventional vibrational motor since it utilizes a pair of high frequency ceramic oscillator and a vibration plate. CONSTITUTION: A ceramic oscillator includes a pair of high frequency ceramic oscillators(10,12), a vibration plate(14), a plurality of electrodes(16,18,20) and a vibrational transfer frame. The pair of high frequency ceramic oscillators(10,12) have a thickness different from each other in such a way that they have a resonance frequency with a difference of about from 10 to about 102 Hz. The vibration plate(14) is coupled to the pair of high frequency ceramic oscillators(10,12). The plurality of electrodes(16,18,20) is formed on each of the high frequency ceramic oscillators(10,12) and one side of the vibration plate(14) to apply an electrical energy. And, the vibrational transfer frame transfers the vibration of the vibration plate(14) in response to the apply of the electrical energy to the body. |
