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: 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.

Abstract: An acoustic transducer includes a housing, which may be a circular cylinder or may have a rectangular cross-section. Two permanent magnets that closely fit the inside of the housing are joined by a linkage having a high magnetic permeability to form a piston that is inserted into the housing. Two pole coils surround the housing with each coil adjacent one of the permanent magnets. The coils are arranged to cause the piston to oscillate within the housing and emit sound waves when coupled to an electrical signal. One end of the housing may be closed except for a barometric leak. A third permanent magnet or a spring may provide a restoring force that centers the piston between the coils when the piston is not subjected to other forces. One of the permanent magnets on the piston may include a vent passage.
