[0052] The housing 210 may include an inner surface 211 a and an outer surface 211 b. The inner surface 211 a may define an interior space 212 of the housing 210. The interior space 212 of the housing 210 may be fluidly sealed from the external environment by the housing 210. For example, the outer surface 211 bis exposed to the external environment, but the internal space 212 and the components located in the internal space 212 (e.g., electronic components such as a processor, memory, bus, wireless communication device, wiring, etc., audio exciter, 2 50, etc.) is the outer surface 2 11 b is sealed from exposure to any fluids and / or gases to which it may be exposed in the external environment.

[0053] In some non-limiting embodiments or aspects, the housing 2 10 may include a flat panel display 216. For example, the flat panel display 216 may form part of the exterior surface 211b of the housing 210.

[0054] The audio exciter 250 may be connected (e.g., directly connected, etc.) to the interior surface 211 a of the housing 210 and fluidly sealed from the external environment by the housing 210. Thus, openings or gaps in the housing 210 of the medical device 200 may be reduced or completely eliminated while still providing audio output from the medical device 200. Furthermore, the use of a membrane over the speaker may include porous openings to muffle sound and / or degrade over time with multiple cleanings and / or make the housing thin enough to allow some sound to re-transmit, avoiding muffling or a drop below the desired volume. In contrast, with the audio exciter 250 connected to the interior surface 211 a of the housing 210, the housing 210 (e.g., the entire housing 210, a surface of the housing 210, etc.) may generate audio output through the movement of material within the housing 210 itself, with the audio exciter 250 sealed within the housing 210 without any openings for liquids to enter during cleaning or grates or gaps for material to accumulate within.

[0055] In some non-limiting embodiments or aspects, audio exciter 250 may include an ASX02604-R audio exciter and / or an ASX02108-R audio exciter, each manufactured by PUI Audio, Inc.

[0056] In some non-limiting embodiments or aspects, audio exciter 250 may be connected (e.g., directly connected, etc.) to a portion of interior surface 211 a of housing 210 that includes flat panel display 216. For example, audio exciter 250 may be directly connected to the back side of flat panel display 216, opposite the display side of flat panel display 216. Thus, with audio exciter 250 connected to the back side (non-display) of flat panel display 216, a panel of the display (e.g., a glass panel, etc.) is moved by audio exciter 250 in a direction facing a user viewing flat panel display 216, directing sound toward the user.

[0057] In some non-limiting embodiments or aspects, for example, as shown in FIG. 2F , the portion of the interior surface 211 a of the housing 210 to which the audio exciter 250 is connected may be directly opposite and connected to another portion of the interior surface 211 a of the housing 210 that includes the flat panel display 216.

[0058] In some non-limiting embodiments or aspects, the portion of the outer surface 211b of the housing 210 opposite the portion of the inner surface 211a of the housing 210 to which the audio exciter 250 is connected may include a plurality of raised portions 215 spaced apart from one another and extending from the outer surface 211b of the housing 210. For example, the audio exciter 250 may be connected to the inner surface 211a of the housing 210 between the plurality of raised portions 215 extending from the outer surface 211b of the housing 210. In some non-limiting embodiments or aspects, the plurality of raised portions 215 includes at least three raised portions. For example, FIGS. 2F-2I show non-limiting embodiments or aspects of the medical device 200 including four raised portions 215.

[0059] Thus, the plurality of raised portions 215 may be 0 0 of the outer surface 211b of the audio exciter 25 A gap may be provided between the portion of the inner surface 211a opposite to the portion to which the audio exciter 250 is attached and the surface (e.g., a flat surface, etc.) on which the medical device 200 is placed. This allows the audio exciter 250 to 0 The outer surface 211b can be moved without touching the surface on which the medical device 20 is placed, and the outer surface 211b can be moved through the gap. 0 This can improve air movement for sound to escape from underneath. For example, the mass of the housing 210 can be supported at the outer corners of the housing 210, thereby providing a slight elevation above the surface on which the medical device 200 rests, allowing sound to escape and providing the desired volume.

[0060] In some non-limiting embodiments or aspects, the portion of the inner surface 211 a of the housing 210 to which the audio exciter 250 is connected includes a recess 217, and the thickness between the inner surface 211 a and the outer surface 211 b at the recess 217 is less than the thickness of the housing 210 surrounding the recess 217. For example, the recess 217 can be located on the inner surface 211 a between multiple raised portions 215 extending from the outer surface 211 b of the housing 210.
