Abstract
Disclosed herein is an underwater pager configured such that a hole is not formed in the outer wall of a casing. The ultrasonic underwater pager includes an ultrasonic transducer for transmitting or receiving ultrasonic signals. An electronic circuit unit generates an ultrasonic signal and analyzes a received ultrasonic signal. A switch unit is switched using a magnetic phenomenon and is configured to supply power to the electronic circuit unit and transmit external commands to the electronic circuit unit. A watertight casing is configured such that the ultrasonic transducer, the electronic circuit unit, and the switch unit are installed in the watertight casing, the ultrasonic transducer being installed in a raised position in the watertight casing using a molding process. A magnet is attached to a rubber cover connected to an outside of the watertight casing, and is configured to switch on/off the switch unit using a magnetic phenomenon.
