FIG. 1 is a plan view of a speaker, an amplifier, and a power source housed in one watertight case. Figure 2
is a perspective view of a cross section of the case. The speaker mounting part of the case also functions as a diaphragm, so the thinner it is, the better it will vibrate, but since it needs a water pressure resistant structure, the thickness should be 4 to 5 mm. Figure 3 shows a diver putting this underwater speaker into his BC jacket.
The throat microphone cord is connected to an underwater speaker and used as a communication device.
