Description
【考案の詳細な説明】 この考案は水中音響受波装置の構造に関する。[Detailed explanation of the idea] This invention relates to the structure of an underwater acoustic receiver.
水中音響を聴取する場合、水中音響は受波器により電気
信号に変換されてから解析されるが、該電気信号は微弱
であり、且つ解析装置までの伝達距離が大なるため、前
記増巾器を必要とする場合が多い。When listening to underwater sound, the underwater sound is converted into an electrical signal by a wave receiver and then analyzed. However, since the electrical signal is weak and the transmission distance to the analysis device is long, it is necessary to use the amplifier. is often required.
一方水中に水中音響受波器と前記増巾器とを吊下する場
合には、操作に便利で水圧の影響を受けないように全体
の組合せ構造を単純化する必要があり、また多数の受波
器を数珠状に連結してアレーを構成する場合には、受渡
器は特に小形、軽量なることが要求される。On the other hand, when suspending an underwater acoustic receiver and the amplifier underwater, it is necessary to simplify the overall combination structure so that it is convenient to operate and is not affected by water pressure. When corrugators are connected in a beaded manner to form an array, the delivery device is particularly required to be small and lightweight.
そこで、本案の目的とするところは、上記諸要請を満足
する水中音響受波器を提供するにある。Therefore, the object of the present invention is to provide an underwater acoustic receiver that satisfies the above requirements.
以下本案の図示実施例について説明すると、１は薄肉円
筒状の圧電変換素子部で、円筒端面にアルミ製端板２を
固着して内部を密閉中空室とし、該中空室に圧電変換素
子部１に組合わされる前置増巾器３（図は円筒ケース内
に収納したものを示す）を内装する。The illustrated embodiment of the present invention will be described below. Reference numeral 1 denotes a thin-walled cylindrical piezoelectric transducer section, and an aluminum end plate 2 is fixed to the end surface of the cylinder to form a sealed hollow chamber. A preamplifier 3 (the figure shows a preamplifier housed in a cylindrical case) to be combined with the cylindrical case is installed inside.
前置増巾器３は圧電変換素子部１の内面に接触せず、こ
れとの間に気密室４が介在するように両端が端板２に固
定され、前置増巾器３の接続電線５は端板２を貫通して
外部に引き出される。The preamplifier 3 does not contact the inner surface of the piezoelectric transducer section 1, and both ends are fixed to the end plate 2 so that an airtight chamber 4 is interposed between the preamplifier 3 and the connecting wire of the preamplifier 3. 5 penetrates the end plate 2 and is drawn out to the outside.
気密室４は圧電変換素子１を音圧変化に従って忠実に振
動させる作用をなすもので、大なることを要しないから
、圧電変換素子部１は受波面が中空円筒形で大であると
共に内部空所を前置増巾器３の収納に有効に利用し得て
、受波器全体が感度の割に小形軽量となる。The airtight chamber 4 functions to vibrate the piezoelectric transducer 1 faithfully according to changes in sound pressure, and does not need to be large. The space can be effectively used for housing the preamplifier 3, and the entire receiver becomes small and lightweight considering its sensitivity.
本案は上記構成を有し、圧電変換素子部と前置増巾器の
組合せ体が小形、軽量であり、外形が円柱形できわめて
単純であって取扱いに便利であると共に、水圧の影響を
受けることが少い等の効果がある。The present invention has the above configuration, and the combination of the piezoelectric transducer part and the preamplifier is small and lightweight, has a cylindrical outer shape, is extremely simple, is convenient to handle, and is not affected by water pressure. It has the effect of reducing the number of occurrences.
