Abstract:
The 6B crystal projector is an underwater sound projector designed primarily for short range testing work. Sound pressures are radiated from diaphragm, which is driven by an array of ninety-six 45 deg Y-cut Rochelle salt crystals connected in parallel mounted between diaphragm and steel backing plate. It can be used from below 5 kilocycles to above 100 kilocycles per second, the most useful range being from 10 to 80 kilocycles. Projector may also be used as a hydrophone.
