Abstract
147,938. Signal Ges. Nov. 1, 1916, [Convention date]. Subaqueous audible signals.-Sound exciting or detecting forces are brought into play between a mass m1, fixed to the diaphragm a and an equal or smaller mass m2 supported on the diaphragm by springs f. In the construction shown in Fig. 1. an exciting or detecting magnet acts between the two musses, while in the receiver shown in Fig. 2, the two masses form the electrodes of a microphone. In estimating the masses m1, account must be taken of the effective mass of the diaphragm itself and of the water which moves with it, represented by the hemisphere z.
