GENERATING DEVICE OF MULTI-BRANCHED WATER FLOW CONTAINING UNDERWATER SOUND

PURPOSE:To obtain a multi-branched water flow containing only water balls produced by underwater sounds by providing a ring permanent magnet around a vibrating coil, and mounting this magnet on a core having a cylindrical projection fitted to the inner part of the vibrating coil in the center part. CONSTITUTION:A underwater sound generator 11 has a middle bottom 14 nearly in the center of the height of a standing cylindrical body 13, and a circular rubber vibrating membrane 15 pressed to the upper end by a ring membrane presser 16 and fixed and clogged by a number of screws 17. A vibrating coil 18 is adhered to the center part of the vibrating membrane 15, a ring permanent magnet 20 is disposed around the coil 18 with a slight gap G with the coil 18 and mounted on a circular seat 19a formed on the lower end of a core 19 having a cylindrical projection fitted to the inner part of the coil 18 in the center, and the core 19 is fixed onto the middle bottom 14. The water injected through a feed water pipe 2 is passed through a feed water hole 3 and entered into a lower body 1, and when it is passed through a sponge 23, the water is rectified by the synergism between the elasticity of the sponge 23 itself and the volumetric elasticity by the sum of the airs contained in an air basin 24 and the sponge 23 upper than a water level W.
