Abstract: An electronic device includes a housing having an opening comprising an audio port and a speaker assembly carried by the device housing. The speaker assembly includes a water ejection system having a diaphragm coupled to a magnetic driver and a mesh that covers the audio port where the diaphragm and the mesh together define an acoustic volume. When a water ejection signal is received at the magnetic driver, the magnetic driver is caused to move the diaphragm in a manner that ejects water contained within the acoustic volume out of the acoustic volume and through the mesh.

Abstract: An optical module for a display system includes a lens, a display screen, a movement mechanism, and one or more pressure-relieving features. The display screen cooperatively defines a chamber with the lens. The lens and the display screen are moved relative to each other by the movement mechanism. The one or more pressure-relieving features are in fluid communication with the chamber to hinder pressure in the chamber as the lens and the display are moved relative to each other.

Abstract: An audio speaker having an adsorptive insert in a speaker back volume, is disclosed. More particularly, an embodiment includes an adsorptive insert having a rigid open-pore body formed by bonded adsorptive particles. The rigid open-pore body includes interconnected macropores that transport air from the speaker back volume to adsorptive micropores in the bonded adsorptive particles during sound generation. Other embodiments are also described and claimed.

Abstract: A micro speaker having a capacitive sensor to sense a motion of a speaker diaphragm, is disclosed. More particularly, embodiments of the micro speaker include a conductive surface of a diaphragm facing conductive surfaces of several capacitive plate sections across a gap. The diaphragm may be configured to emit sound forward away from a magnet of the micro speaker, and the capacitive plate sections may be supported on the magnet behind the diaphragm. In an embodiment, the gap provides an available travel for the diaphragm, which may be only a few millimeters. A sensing circuit may sense capacitances of the conductive surfaces to limit displacement of the diaphragm to within the available travel.

Abstract: An acoustic module, such as a microphone or speaker module, includes an acoustic membrane that vibrates to produce acoustic waves and an acoustic cavity through which acoustic waves produced by the membrane travel. A liquid removal mechanism removes liquid from the acoustic cavity. Such a liquid removal mechanism may include the acoustic membrane, heating elements, hydrophobic and/or hydrophilic surfaces, and so on. In some cases, the liquid removal mechanism may remove liquid from the acoustic cavity upon connection of the acoustic module and/or an associated electronic device to an external power source.
