【発明の詳細な説明】
本発明は低雑音で強度的に安定した水中受波器に関する
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a low noise and intensity stable underwater receiver.

受波器部品であり、音響媒体２及びロープ状のテンショ
ンメンバ３と共に瞳体４内に充填されている。Figure 1a is a cross-sectional view showing a conventional underwater receiver, Figure 1b
1 is a vertical cross-sectional view, and numeral 1 denotes a receiver component that includes a receiver element, an electronic circuit, etc., and is filled in the pupil body 4 together with an acoustic medium 2 and a rope-shaped tension member 3.

れにより萱体内部に圧力変動が生じて受波素子の雑音出
力になるという欠点を有していた。However, in conventional underwater receivers with this configuration, when tension is applied from the outside, the tension member is rope-shaped, so strong vibrations like the natural vibration of a string are likely to occur, which causes pressure inside the shell. This has the drawback that fluctuations occur, resulting in noise output from the receiving element.

欠点もあった。Further, when an external force such as bending or twisting is applied to the armor body, the tension member comes into contact with the receiver component, and an excessive external force is applied to the receiver component at the contact portion, making it easily damaged.
本発明はこれらの欠点を解決することを目的とし、その
ため筒状等のテンションメンバを崖体の肉厚部中に埋設
したことを特徴とする。The present invention aims to solve these drawbacks, and is characterized in that a cylindrical tension member is embedded in the thick part of the cliff body.

品１を音響媒体２と共に充填したものである。To explain the following with reference to the drawings, FIG. 2a is a cross-sectional view showing an embodiment of the present invention, FIG. 2b is a vertical cross-sectional view, and 1 is a receiver component incorporating a receiver element, an electronic circuit, etc.; 2 is an acoustic medium, 5 is a pupil body, and 6 is a tension member, such as a cylinder, embedded in the thick part of the body 5, and in the present invention, the tension member 6 is embedded in the thick part in this way. A receiver component 1 is filled in a crab body 5 together with an acoustic medium 2.
このような構成を有する本発明の水中受波器によれば、
テンションメンバが陸体の肉厚部中に埋設されており、
かつ該テンションメンバはロープ状ではないため、外部

固有振動のような強い振動の発生が抑制され、その振動
に起因する雑音を低減することができる。According to the underwater receiver of the present invention having such a configuration,
The tension member is buried in the thick part of the land body,
In addition, since the tension member is not rope-shaped, even if tension is applied from the outside, the generation of strong vibrations such as the natural vibration of strings found in conventional underwater receivers is suppressed, and the noise caused by the vibrations is suppressed. can be reduced.
また、本発明の水中受波器は外力が加わっても、この外

って受波器部品の破損を防止することができる。In addition, even if an external force is applied to the underwater receiver of the present invention, this external force is applied to the casing in which the tension member is buried, so that no unreasonable force is applied to the receiver parts inside the cliff. Damage to the corrugated parts can be prevented.
以上説明したように本発明は、外部張力に基づくテンシ

受波器部品に不要な外力が加わるのをなくすことができ

ることができる。As explained above, the present invention can suppress the vibration of the tension member based on external tension, and can also eliminate unnecessary external force from being applied to the receiver components in the vibration body. This makes it possible to realize a stable underwater receiver.
