Abstract: An audio speaker including a bobbin-less voice coil having epoxy-bound winding layers is disclosed. More particularly, a voice coil may include a first winding layer and a second winding layer coaxially arranged about a central axis. The winding layers may include respective wire turns coiled about the central axis in a longitudinal direction. The winding layers may be bound by an epoxy matrix. For example, the epoxy matrix may be disposed radially between the first winding layer and the second winding layer to bond first wire turns to second wire turns, and to bond the winding layers to a speaker diaphragm.

Abstract: An audio speaker having a voicecoil running along a diaphragm surface, and a magnetic array, e.g., a Halbach array, configured to direct a magnetic field toward the voicecoil to drive the diaphragm and generate sound. In an embodiment, multiple Halbach arrays are used to drive the same voicecoil winding or to drive separate, respective voicecoil windings on the diaphragm surface. Other embodiments are also described and claimed.

Abstract: A portable computing device that includes a base portion that carries an audio module and a display housing that carries a display is disclosed. The display housing is coupled with, and rotatable with respect to, the base portion. The display housing includes a magnet, and the base portion includes a magnetic field sensor that detects an external magnetic field of the magnet. The magnetic field sensor provides a signal that deactivates the display. In order to reduce layout changes in the portable computing device, the magnetic field sensor is positioned in an audio housing that carries the audio module. However, the magnetic field sensor is designed and oriented to detect the magnetic field from the magnet in the display housing and effectively ignore magnets associated with the audio module. In order to reduce the amount of electrical connections, the magnetic field sensor is electrically coupled to the audio module.

Abstract: An electronic device including a frame member suitable for use with an audio driver is disclosed. The frame member may include a recessed region that receives the audio driver. The frame member may further include a flange member surrounding the recessed region. The frame member may be formed from a material having a relatively high coefficient of thermal conductivity. Accordingly, the frame member can dissipate thermal energy (heat) generated from the audio driver. In addition, the frame member may be seated in an enclosure of an electronic device in a manner that allows the frame member to pass the thermal energy to the enclosure. Also, the frame member may include a ferromagnetic material, which may cause the frame member to direct magnetic flux from a magnet of the audio driver in a desired manner.

Abstract: A decoupled speaker membrane assembly for a microspeaker, the membrane including a first membrane portion, a compliant portion, a second membrane portion and a suspension member. The compliant portion is attached to, and extends radially outward from, an entire perimeter of the first membrane portion. The second membrane portion is attached to, and extends radially outward from the compliant portion such that the second membrane portion is decoupled from the first membrane portion by the compliant portion. The suspension member extends radially outward from the second membrane portion.

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.
