1. An acoustic transducer capable of converting mechanical motion into acoustical energy comprising:
- a diaphragm;
a support on one portion of said diaphragm including an actuator operatively coupled to a second portion of said diaphragm wherein said support and actuator are separated by a distance and are capable of relative motion to adjust said distance.

Abstract
An acoustic transducer is disclosed that is capable of converting mechanical motion into acoustical energy may include a diaphragm and a support on one portion of the diaphragm. An actuator may then be provided that is operatively coupled to a second portion of the diaphragm. The support and actuator may be configured to be environmentally responsive to surrounding conditions of, e.g., heat and/or humidity which may then substantially maintain the diaphragm'"'"'s acoustic performance.
