Definitions

  • FIG. 4A shows a projection of the emitted sonic energy of FIG. 4 along line 4A-4A.
  • the transducer 15 and certain components shown in FIGS. 5-9 includes a ferro-magnetic base 40 in which is mounted magnet 38 and ferro-magnet circular pole piece 41 and an outer pole piece 46 located about pole piece 41 leaving an annular air gap 42 for the flux of magnet 38.
  • Non-ferromagnetic annular member 37 maintains the alignment of the air gap 42 between outer pole piece 46 and inner pole piece 41 without shunting the field in the air gap 42.
  • the magnet 38 provides magnetic flux through inner pole piece 41 across the air gap 42 through outer pole piece 46, base 40 and back to the bottom of magnet 38.
  • Diaphragm 45 having an annular shape for mounting over slot 42 includes ring 44 which fits into slot 42 and is capable of movement therein.
