SOUND PROPAGATION IN AN ENCLOSED DEVICE

Abstract: in general, the disclosure describes techniques for generating sounds in fully sealed medical devices. the example techniques for generating sounds in medical devices include the use of a plurality of sound chambers arranged in a stacked configuration that propagate the sound, along with one or more diaphragms configured to vibrate in response to the sound propagating through the medical device. in one or more examples, an external housing that includes an overlay cover may fully enclose the medical device, where the overlay cover (e.g., the entire overlay cover or a part of the overlay cover) also vibrates to propagate the sound out of the medical device.
