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: This disclosure describes a speaker assembly suitable for use in a portable electronic device utilizing water resistant ports. The speaker assembly can have an open back that subjects a back volume of the speaker to pressure differentials within a device housing of the portable electronic device. The speaker assembly can utilize a speaker surround having a varying thickness. The varying thickness speaker surround allows the speaker to maintain an acceptable frequency response profile while limiting the travel of the diaphragm it is coupled with. The disclosure also describes how electrically conductive pathways can be integrated within a housing of the speaker assembly.

Abstract: An electronic device having a microphone behind a water resistant, air-impermeable membrane is disclosed. Embodiments include a trapped volume of air between the membrane and the microphone. A barometric equalization element may define an acoustic leak path, e.g., a tortuous leak path, between the trapped volume of air and an encased space within a casing of the electronic device. Other embodiments are also described and claimed.

Abstract: A diaphragm for an audio speaker includes an outer shell and an inner shell. Each shell has a face portion and an edge portion that is formed to be substantially perpendicular to the face portion. The inner shell is inserted into the outer shell such that at least a part of the edge portion of each shell is in contact with at least a part of the edge portion of the other shell and a space is formed between the face portions of each shell. A cellular core fills the space formed between the face portions of each shell and is bonded to the face portion of each shell. The outer and inner shells may have identical sizes and shapes such that there is an interference fit between the contacting edge portions. A voice coil may be supported by the edge portions.

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: A planar magnetic driver including a radiating surface having a trace-free central region is described. The driver has a magnet defining an acoustic opening on a central axis. A diaphragm of the planar magnetic driver is held by mounts having a mounting profile around the central axis, and the diaphragm includes a radiating surface facing the acoustic opening. An innermost conductive trace on the diaphragm extends around a central region of the radiating surface within a magnetic flux of the magnet such that no conductive traces are on the central region. A radial distance between the innermost conductive trace and the mounting profile is less than another radial distance between the innermost conductive trace and the central axis. Accordingly, an excursion range of the diaphragm along the central axis is greater than a gap distance between the conductive trace and the magnet. Other aspects are also described and claimed.
