[Detailed description of the invention] This invention incorporates a ceramic vibrator consisting
of a piezoelectric element and a common element for mechanical-electrical energy quality
collection, and is attached with a large base 11c plastic thin plate over 9 cases o # oll KJl Sono
Yosera (y-k-mi-n-phone). Although it is configured as shown in the conventional ultrasonic
ceramic ceramic company, ? 1 to ? 2 @ l. That is, the piezoelectric ceramic element 2 is
attached by bonding 113 on IIP # Ik 1 and the aluminum core 4 is electrodeposited on the upper
portion of the piezoelectric ceramic element 2 and these are attached to the upper-bore 111K
ring 6 II1. It is composed by singing in the case 6 which has been lost. This ? iodide fkm formed
into the vertebral 1 Welfare, umbilical 6 duck dust or iodine fkm formed into the vertebral 1
Welfare, umbilical 6 duck dust and 2-water droplets penetrate, they aluminum Kyowashiko 4 and
EEt ceramic element 2 It was attached to cause a decrease in sensitivity. It was ? SS??e to be
used under heavy dust and water drops. In order to eliminate such a defect, it is considered that
simply pasting [flIlT port IIK synthetic resin 011 II], but in the case of the kernel, as shown in
aSS, the sensitivity of receiving ultrasound 2 +- It had a drawback that it was reduced, t, and the
ripple of the number of losses was 0 or increased. As described above, the present invention is
intended to eliminate the drawbacks of the conventional technology. After that, I presume this

invention by one reason of 1 ? m. The end of the insulation base 1 is an insulation 1 base made
of a synthetic resin and the like, and this child base 8 is provided with a child 8. Furthermore, the
earth surface of this insulation base base T is piezoelectric through the elastic Ill agent. The II
container 10 is cut in one piece, and on the bulk of the piezoelectric ceramic container, arly #
forceps 11 or 111 are cut. From the upper FIIF tq device element 1o, a reet 102 is drawn and
electrically shaken at the terminal 8. 3 pieces-2? 'And these are decorated with case 1a, and the
opening 11 114 of the case 13 is regular or irregular, m-like lumps or lumps 115 (r made of
synthetic resin thin film , Membrane 16 is attached. ? As mentioned above, even if it is used as
an oscillation, even if it is used for oscillation, there is no reduction in output, and in the case of
habituation, if it is habitual practice Even if there is no decrease in the sensitivity as shown in
dX6-, the ripples on the skin ripple 4I may be too large. We can do seven things that we added. In addition, it completely blocks the penetration of the back plane, water, and materials, and so
on.
