DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tip high water
resistant boot touch transducer that uses a ring-shaped peristaltic element. Conventionally, a
structure as shown in FIG. 1 is used for this type of transducer, and due to an increase in external
force due to water pressure, the boot 1 made of rubber or the like squeezes into the space 15 ?
? ? ml of the ring slider 2 and the spacer 3 As shown in Figure 2, Km mover and Sube /,-Chang. ?, push the gap upwards or downwards and squeeze the gap [Camp, CA nlS 1-'L / ?? / и
QV 'As a result, the boot l continues to bite in proportion to the gap's extension and the amount
is finally This type of boot cod has been used for low water pressure applications because it has
the disadvantage that the boots may be broken and may flood within the transducer. In the
figure, 5 in. 5 ind., 6 indicates a screw. The gap is required in terms of acoustic characteristics,
and it can be taught that the gap is filled with a soft material. This invention provides a boot
touch transducer that solves the above 10 points and can withstand high water pressure by
adopting a structure in which the relative position between the ring-shaped vibrator and the
spacer does not change. is there. Next, embodiments of the present invention will be described
with reference to the drawings. FIG. 3 is a block diagram (cross-sectional view) of an embodiment
of the present invention. Swallow at both ends of the Therefore, because the gap 4 between the
key 2 and the space 4 does not change, the high water pressure resistant boot touch type
transmitter / receiver is also effective in preventing the biting of the boot 1 even under high
water pressure. 202-The present invention has been described above: Tiger, but limited to the
use of low water pressure The boot touch transducer can be used in high water pressure from K
to prevent biting in the boot due to an increase in pressure It has the effect of
