1. An electronic device comprising:
- a housing;
a display in the housing;
an acoustic module in the housing, wherein the acoustic module includes an acoustic element, a voice coil, and a cavity that is acoustically coupled to the acoustic element, and wherein the acoustic element is configured to generate an acoustic pulse that facilitates movement of liquid within the cavity; and
a screen covering the cavity, wherein the screen is configured to prevent liquid ingress into the cavity and wherein the screen is configured to facilitate the expulsion of liquid out of the cavity.

Abstract
A device having one or more an acoustic modules. The acoustic module includes an acoustic element and a cavity that is acoustically coupled to the acoustic element. The module also includes a first conductive element that is configured to generate a first surface charge on a first region of an interior surface of the cavity. A second conductive element is configured to generate a second surface charge on a second region of the interior surface of the cavity. The first and second charge on the first and second regions of the interior surfaces of the cavity may be selectively applied to facilitate movement of a liquid held within the cavity.
