Abstract
PURPOSE:To prevent the variance in resonance frequency accompanied with the variance in mechanical size, by clipping an oscillator with a conductive elastic body. CONSTITUTION:A plurality of oscillator elements 1 are clipped with two conductive elastic devices 2 and contained in an external case 5 with a retaining plate 4. Electric wires 6 are drawn out from an electrode 3 in the conductive elastic device and led out externally with a cable 7. The oscillators 1 are coupled with the devices 2 through the electrode 8 of the oscillator. Thus, the need for electric wires connecting the electrodes 2 of the oscillators 1 is eliminated and the process of soldering is saved, allowing to prevent the variance of resonance frequency due to the variance of mechanical size.
