DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement
of a water-in-the-ball girdle transmitter-receiver (hereinafter referred to as a transmitter-receiver)
for use in underwater acoustic equipment such as sonar, and the object of the present invention
is to Holding the piezoelectric material (hereinafter referred to as spherical-shell piezoelectric
material) at two points greatly improves its holding strength. There are nine points in the
structure. ? l ? @ 0 @ 0 reception reception excellent structure is jlIIall As shown in the cross
section m of the figure, one end of the spherical shell piezoelectric body 1 is penetrated by the
support rod 21 -A) non-no-self "-" "/ and the lead @ 3 penetrating the inside of the support rod 2
It has a wedge structure in which the electrode K11 of the spherical shell piezoelectric body is
connected to the 3 '. Here, the holding of the spherical shell piezoelectric member l is performed
by bonding SS, and only when the transducer is held in the flowing water, the force received by
the spherical shell piezoelectric member from the fluid when moving the water at high speed
There is a possibility that the joint s5 and the waterproof coating 4 may be broken in the
rounding where the joint 111iK concentrates, and water may infiltrate into the inside of the
cylinder. It had various disadvantages, such as the need to pay careful attention to the
application of force. In addition, the function as an O transducer is limited to the range of being
simply used as an omnidirectional O transmitter or delivery device. There are K to provide a
transducer. In order to achieve the above object, according to the present invention, the
transducer for submerged water according to the present invention is a transducer for water
using a hollow ball rod piezoelectric material as a broken body, wherein at least two points of the
ball rod piezoelectric material are used. It is characterized by being supported by a support rod.
==-Hereinafter, embodiments of the present invention will be described with reference to the
drawings. The cross-sectional views of FIG. 2 and the third garden showing the example of the
present invention 0 * are shown in FIG. 1 and in FIG. In the present invention, the front end of
the support rod 2 and the bottom of the ball shell 1'O are m. Also, the lead wire 3.3 'is notched to
remove the control of the support rod 2 and removed. Fig. 3 shows an example in which the
supporting rod is further extended and the transducer 6 'of the rope 2 is provided on the -PK of
the conventional transmitting and receiving a16. The lower transducer can be used as a receiver.
In addition, it is possible to increase the number of transducers to 211.3 ? ?, and it is also
possible to run various instructional t, etc., so the function of this type of transmission and
reception can be significantly increased. As shown in the figure, the support rod of the
underwater transmitter-receiver 1 / l iL transducer according to the present invention is
extended, and a second junction is provided at the JiI portion of the ball-shell piezoelectric body
by Ob, the transducer Strong change is only greatly improved 2. Conventional transmission and
reception f!
The provision of several transducers in the lower part 11 significantly increases the range of use
of this kind of transducers. 4, 1lill Brief Description 1N 111 Fi Cross section of a conventional
