Abstract: The musical or striking watch is provided with an acoustic radiation arrangement. The watch includes a watch case, formed at least of a case middle and a back cover removably fixed to the case middle, and at least one crystal for closing said case. The acoustic radiation arrangement includes a connecting support part fixed in the case back between a back bezel and a back crystal. The back bezel includes several lateral openings. A cavity is defined between the connecting support part and the openings in the back bezel.

Abstract: Disclosed are methods and devices that include a therapeutic fluid dispensing device (10) to deliver a therapeutic fluid into a body of a patient. The device includes a controller to control one or more of fluid delivery operations and notification operations, at least one auditory notifier (800) to produce one or more acoustic signals in response to application of one or more activation signals by the controller and a plurality of electrical contacts coupled to the at least one auditory notifier to enable the application of the one or more activation signals to the at least one auditory notifier. The device also includes at least one housing retaining the at least one auditory notifier therein, the at least one housing being structured to resonate at least one of the one or more acoustic signals produced by the at least one auditory notifier in response to application of at least one of the one or more activation signals.

Abstract: The invention is an modified audible signal, such as a piezoelectric noise-making and audible signaling device, which further includes a hydrophobic covering material, such as polytetrafluoroethylene (PTFE). The hydrophobic covering material is known to be water resistant, but does not effect the sound of the audible signaling device, thereby delaying or preventing the failure of the audible signaling device from water corrosion.
