More Information
Summary:An implantable medical device includes a housing defining a hermetically sealed chamber and includes a diaphragm portion having a first resonance frequency, an acoustic communication circuit within the chamber, and an acoustic transducer within the chamber. The transducer includes a substantially rigid pin member attached to an inner surface of the diaphragm portion, and an active portion coupled to the pin member. The active portion has a second resonant frequency and includes a piezoelectric element electrically coupled to the acoustic communication circuit. The diaphragm portion and the active transducer portion may be configured such that the first and second resonance frequencies are substantially equal.
