Description

CROSS REFERENCE TO RELATED APPLICATIONS This application claims the benefit of priority to U.S. Provisional Application Ser. No. 63/420,115, filed on Oct. 28, 2022, entitled “PIEZOELECTRIC COMPONENT INSTALLED IN A FLOATING CONFIGURATION IN AN IMPLANTABLE MEDICAL DEVICE,” which is incorporated by reference herein in its entirety. BACKGROUND A conventional configuration for producing an alarm signal in an implantable device uses a custom flex-circuit with an oscillating component that is embedded and fully adhered to an inner assembly of a device or an inner surface of an enclosure of the device. The enclosure and the inner assembly are part of the acoustic resonance. Therefore, any constraint in the device can impact sound. Additionally, the sound of the alarm signal can be affected when the function of the oscillating component is impaired by forces applied to the enclosure. For example, the sound can be impacted when the device is slightly compressed. In another conventional configuration, an oscillating component can be fully adhered to the device assembly. Such constraint of the oscillating component does not allow the oscillating component to perform its function, and, as a result, the sound of the alarm signal produced can be affected. Considering that sound from the alarm signal can be used to notify the patient of an emergency, the reliability of this safety feature is important. OVERVIEW This overview is intended to provide an overview of subject matter of the present patent document. It is not intended to provide an exclusive or exhaustive explanation of the invention. The detailed description is included to provide further information about the present patent document. The present inventors have recognized, among other things, that the present subject matter can be used to reliably mount a component within an implantable medical device. In various examples, the present subject matter is advantageous in that it decreases space requirements and, in turn, allows for a smaller device. Also, the present subject matter is advantageous in that it allows for the use of relatively inexpensive, off-the-shelf components. The present subject matter can be used to reduce, if not eliminate, the need for custom parts, potentially reducing costs and design risks associated with production of a device. The present subject matter can be used to provide a component with performance that is more immune to external forces applied on a device within which the component is mounted, thereby providing a more reliable component, such as, but not limited to, a piezoelectric alarm signal component.
