| 20110274301 | Underwater Transducer Apparatus Using Polarized Stacked Piezoelectric Elements and a Method of Operating the Same - The current device is a transducer for underwater communication using a plurality of stacked polarized piezoelectric elements. The piezoelectric elements are stacked within a communication device such as a loudspeaker or a set of headphones or earphones so that the polarity of each element is orientated in the same direction. When the elements are activated, the elements operate in phase and drive a pressure or sound wave to its intended recipient at a significantly high volume. The transducer may also be configured to receive acoustic signals within a device such as a microphone by collecting the acoustic signals in phase by the stacked piezoelectric elements from a user. The elements convert the acoustic signals to electrical signals which are then transmitted to another user. | 11-10-2011 |
