DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transducer
reflector used as an electroacoustic transducer in underwater communication. Conventionally, as
shown in FIG. 91, this type of transducer is low in mechanical strength but is made of
nonmetallic reflector 2't1 metal such as sponge rubber or cork rubber which has sound
generation hepta reflection and hollow independent bubbles. Is IK closely attached and used as a
rare-lefter 90-1-2, no ',' 'Af,? −, / Jb ′ y − There was a drawback that the air layer compressed
with these reflectors decreased with the increase of the water pressure, and the reflection
efficiency decreased. 4 shows a transmission sound wave, 7 shows a reception sound wave. The
object of the present invention is to use a reflector made of a pipe having a space, etc., which has
high mechanical strength against mechanical pressure when subjected to water pressure and
extremely small change in reflection efficiency with changes in water pressure. Accordingly, it is
to provide a reflector-scrambler transmitter / receiver 10 capable of maintaining the reflection
efficiency -2 << under a wide range of water pressure. That is, the present invention improves the
decrease in reflection efficiency with the increase of water droplets, and maintains the effective
surface reflection efficiency even under high water pressure, and has a pipe with a large
mechanical resistance. By making the reflector 15 letter made by etc., good reflection efficiency
can be maintained under a wide range of water pressure, and a 7-lever type handset is obtained.
Next, an embodiment of the present invention will be described with reference to the drawings.

view of a reflector type transducer of the present invention, and FIG. 3 is a reflector type
transmission and reception of the present invention. In Fig. 2 and Fig. 3, the transmission sound
wave 4 horizontally compressed by the electro-acoustic transducer 3 hits the space layer 6 in the
pipe 5 and is reflected and transmitted. The sound wave 4 travels vertically, and the reception
sound wave 7 has a reverse route to the transmission 9, and the reception sound wave 7
reflected by the space layer 6 in the pipe 5 enters the electro-acoustic conversion circuit II 3. In
other words, the pipe 5 having a space pipe is used as a reflector by utilizing the property that
the acoustic impedance density of air is high and the sound wave is easily reflected. 15 reflectors
capable of maintaining good reflection efficiency under a wide range of water pressure from K -A
laboratory transducer is obtained. As described above, according to the present invention, the
reflector-type transducer which can only be used in shallow * If is used as a reflector such as a
pipe having space t, so that it is stable and good for use in depth. As well as being able to
maintain the ability to maintain the ability of the computer 203, i &), it is also effective in
simplifying the structure.
