めのものである。Until now, underwater speakers developed for use underwater (under the sea) had to be expensive and expensive due to the complete insulation of water pressure and electromagnetic circuits. Also, if you put a normal dynamics beaker etc. into a sealed metal or other water-resistant case, the case becomes thicker due to the water pressure, which weakens the volume. Therefore, there was a problem in that the danger increased. The present invention is intended to solve these problems relatively easily.

してもよいものである。The details of the present invention will be explained below. Ceramic and other sound wave oscillations due to the piezo effect are generally known. The present invention consists of three layers: a metal resonance plate, a piezo vibration element, and a water-resistant resin film or synthetic elastic body with a thickness that does not control the vibration of the water-insulating tank. 2 and 3 are water-resistant coated electric wires, 4 is a metal resonance plate, 5 is a contact, 6 is a piezo vibration element, 7 is a contact,
8 is a water-resistant insulating material. As shown in the figure, the electric wire 2 is connected to the metal resonance plate, and the electric wire 3 is connected to the surface of the piezo element 4 that is not in contact with the metal plate. The element 4 and the contact point 7 of the electric wire 3 are completely covered with a water-resistant insulating layer 8 except for the surface in contact with the metal plate of the element. The output signal can operate the piezo vibrating element according to the input voltage amplitude even in conductive water, and the vibration is amplified by the metal resonance plate. Piezo elements are driven by voltage, so even though the voltage is relatively high, the current is very small, so the danger underwater can be almost ignored.
