DETAILED DESCRIPTION OF THE INVENTION The present invention reduces the noise generated
when the wave receiver vibrates due to waves, etc., and obtains a good wave receiving sensitivity.
About. Conventionally, suspension of the underwater wave receiving device to receive the
seaborne sound etc. generated by suspending the wave receiver in the water (in the sea) from the
floating body (buoy) which was made to play on the water surface 4 As shown in FIG. 1, a

− Attach the wave receiver 104 via the pull 103, suspend the decoration 105 at the lower part
of the wave receiver 104, and add 1 to the above-mentioned spring constant of the suspension
cable 103 and the mass M of the weight 105 alone. (Fig. 2 shows the vertical movement of the
wave receiver when the floating body is used as the driving source) The figure shows that fo = 6
r, and the shaded area in the figure is the attenuation area). However, in such a configuration, the
water damping effect is sufficient due to the above-mentioned spring constant and the physical
limitation of the mass M <<, particularly, in the case of UCj'J, in the case of 'It wave receiver 0, 6

housed inside and an antenna 1 sunk in the upper part of the moon, A case 5 containing an
electronic circuit is suspended from the no anchor 4 via a cable, and the case 5: The directional
wave receiver 7 is suspended by breaking a string 6 (in the present embodiment, for example, a
rubber string, a cotton tape, etc.) of a filter book (in the present embodiment). Furthermore, the
stray directional receiver-8 is suspended from the directional receiver 7 through the readable cap
and the weight 9 is suspended via the nondirectional receiver 8 sword-strap. Hanging pieces
such as n et al. 7-anchor 3--3 etc. 17i, ipi't (stored in 'l' 2 and drawn out from the floating body 2
during operation and suspended in water Are configured in the same way.
In the above configuration, the fingerless receiver 12), the guard 9 may be fixed directly to the
lower part of the directional receiver 7 by hanging it with a diple or the like. Next, in the above
configuration, the sea anchor 3 is formed in a disk shape as shown in FIG. 4, or 2 g is formed in a
cylindrical shape as shown in FIG. The former disc is made into a foldable old structure like an
umbrella in order to be stored in the floating body, and the latter 0 (moon surface: i, formed by ij,
etc. of readability, etc. and stored in the floating body) It is a small fold at times, and it has a
cylindrically elongated structure at the time of operation. Therefore, the hot water Nt ′ ′ j 1
using the former disc-shaped sea anchor 4 and the water (seawater) in the upper and lower
spherical (dotted line) portions of the anchor 4 work as additional mass − In the directional
receiver 7 and the ant directional receiver 8 caused by the movement of the floating body 2, it is
possible to suppress the vibration in the downward direction and the lateral direction of the
antenna 8 and reduce the noise generation to a part 4-1. In the latter case, the cylindrical sea
anchor 4 has water that has entered this cylinder at t: f! l] 1iffi Mugura and Shitezu @ <ChiTsude, in which said and can be sufficiently reduce the generation of noise is suppressed shaking
similarly. Next, a string connecting the case 5 containing the electronic circuit on the upper side
and the composition-. 'Because it separates the fixed connection of both, and the directional
receiver 7 is a vibration sensor that receives hill waves in the sea, it prevents vibration due to
sound waves,' r ' (It is a force that needs to be mechanically released from the above case), and
the sleep 9 provided at the bottom of this configuration gives = Q to the spring constant
necessary for the suspension cable 3 and All i pieces are suspended vertically. In the electric
operation of this embodiment, when the sound wave is received by the finger [port] 7 and the
nondirectional wave receiver 8 in water, the received sound wave is an electronic circuit in the
case 5. The signal is amplified, multiplexed, sent to the transmitter in the floating body 2 via the
suspension cable 3, and transmitted to the transmitter as an underwater signal by transmitting
radio waves from the antenna 1 in advance. It is According to the present invention having the
above-described structure and action, the lower end of the suspension cable having a spring
property has no anchors, and a mass of water in a part of the anchor is used as an additional
mass. Because it works, it is possible to sufficiently suppress the shake of the wave receiver, and
therefore it is possible to sufficiently reduce the wave size of the wave by the wave movement of
the wave receiver, whereby good results can be obtained. Especially in the low cost and small size
underwater wave receiver which has high sensitivity, it is effective to make a good effect.
