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 waterproof speaker module may include a membrane formed from at least one waterproof and elastic material and a supporting structure. The membrane may include an outer surface, an inner surface, and at least one concave region that is indented toward the inner surface. The supporting structure may be coupled to the membrane and include a support structure that mates with the concave region of the membrane when the speaker is subjected to a hydrostatic load. When the speaker is not subjected to a hydrostatic load, the support structure may contact the concave region. In this way, the membrane may be resistant to tearing or rupture due to hydrostatic load.

Abstract: A microspeaker includes a frame and a diaphragm having length sides that are longer than its width sides. A magnet is positioned below the diaphragm. A yoke includes a base portion positioned below the magnet and sidewalls which extend from the base portion, the yoke sidewalls positioned only along a length dimension of the magnet. A voice coil includes an upper end attached to a bottom face of the diaphragm and a lower end positioned within a gap formed between the length dimension of the magnet and the yoke sidewalls. A first suspension member is attached to the length sides and the width sides of the diaphragm and the frame. The first suspension member is within a first plane. A second suspension member is attached to the lower end of the voice coil and the frame. The second suspension member is in a second plane different from the first plane.

Abstract: A speaker driver including a frame and a magnet assembly positioned within the frame. A sound radiating surface may be suspended over the magnet assembly. The sound radiating surface may include a top face and a bottom face, and the bottom face may face the magnet assembly. A suspension member may suspend the sound radiating surface over the magnet assembly. The suspension member may include a top side connected to the bottom face of the sound radiating surface and a bottom side connected to the magnet assembly. A voice coil extends from the bottom face of the sound radiating surface.

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.
