    Abstract: A speaker apparatus is provided in order to both receive and dissipate heat and to provide acoustic absorption for sound waves propagating through a speaker cavity. The speaker apparatus includes a speaker and a speaker cavity configured to receive sound waves emitted by the speaker for propagation through the speaker cavity. The speaker apparatus also includes a heat dissipation structure disposed at least partially within the speaker cavity. The heat dissipation structure includes a thermally conductive mesh that at least partially fills the speaker cavity. The heat dissipation structure further includes an active element configured to direct heat generated by a component into the thermally conductive mesh for dissipation therein. The thermally conductive mesh is configured to provide acoustic absorption for the sound waves propagating through the speaker cavity.

    Abstract: Aspects of the present disclosure may relate to an apparatus, a method, and non-transitory computer-readable storage medium configured for tuning radio frequency elements. In some aspects, the aspects may relate to at least one radio frequency element, at least one wireless charging, one or more channels configured to run between a first portion at least substantially adjacent to the at least one wireless charging coil and a second portion at least substantially adjacent to the at least one radio frequency element, and a dielectric fluid disposed within the one or more channels.
