Abstract

涉及一种即使在水下等不利条件下也可使用的无线电收发机，包括按下开关后发送声音信号的PTT开关，进行声音的输入输出的声音输入输出部，和发送接收无线电信号的主体部，其特征在于：主体部以外的各构成部相对于主体部而言构成为独立单元，具备在独立单元和主体部彼此间发送接收信号的装置。

Description

无线电收发机
技术领域
本发明涉及一种无线电收发机，具体而言，涉及一种即使在海难救助作业等不利作业时也可使用的无线电收发机。
背景技术
通常，无线电收发机多被携带在室外使用，但随着普及及小型化，利用空气振动的扬声器或麦克风内置于无线电收发机主体内，其不具有充分的防水性。
该类型的无线电收发机在日常生活中使用时不会有特别的问题，但例如在海难救助等水中作业时，一旦在水下，则由于水压而使扬声器或麦克风的振动板容易发生变形，不能使用。另外，因为不能在免提状态下使用，所以难以在海难救助等必须从直升机飞向海中的情况下使用。
鉴于上述现有技术的问题，本发明提供一种具有防水性、可在免提状态下使用的、即使在海难救助作业等不利条件下也可使用的无线电收发机。
发明内容
本发明为了解决上述问题，提供一种具有防水性的无线电收发机，其特征在于，它包括：在戴上作业手套时能够确实地按下开关的较大构成的按讲型的PTT开关，由完全密闭在壳体内的骨传导型扬声器和骨传导型麦克风构成的进行声音的输入输出的声音输入输出部，和发送接收无线电信号的主体部，所述PTT开关和所述声音输入输出部分别相对于所述主体部构成为独立单元，在所述PTT开关、声音输入输出部与所述主体部相互之间具有发送接收信号的装置，为了各使用者可将各构成部装在身体的任意位置上，所述各构成部的相互之间通过充分长的防水型电缆进行连接。
附图说明
图1是根据本发明的防水无线电收发机的斜视图。
具体实施方式
根据附图来说明本发明的实施例。图1是根据本发明的防水无线电收发机的斜视图。该无线电收发机1中，进行声音的输入输出的声音输入输出部2、按下开关后发送声音信号的PTT开关(按下通话开关：push-to-talk switch)3和发送接收无线电信号的主体部4分别单独构成，各构成部具备信号发送接收的信号发送接收部，它们彼此间通过行程(stroke)长的防水型电缆5进行连接。
声音输入输出部2的扬声器2b构成为可将输入声音信号作为骨传导声音来传送的骨传导型扬声器，同时，麦克风2a构成为可通过人骨拾取声音振动并转换成声音信号的骨传导型麦克风，则可成为完全防水型的声音输入输出部。
这些骨传导型扬声器2b和骨传导型麦克风2a可能完全封闭在壳体内，以具有完好的防水性。
因为在海难救助作业时多戴手套，所以将PTT开关3构成得较大，以便在戴手套时也能确实进行操作。
在要求完全免提操作的情况下，通过将对声音进行数字处理而仅以有声来动作的声音启动装置(VOX)安装于主体部4内，可防止由于波或引擎声导致误发送。
产业上的可利用性
如上所述，本发明可分为PTT开关、声音发送接收部和主体部，用户可在喜欢和方便的位置处装在身上使用，即使在部分在水下等不利条件下，由于具备充分的防水性，也可使用，可免提使用，特别适用于海难救助作业等时。
