Abstract: A speaker including a frame, and a magnet assembly coupled to the frame. The magnet assembly forms an air gap through which a magnetic flux is directed. The speaker further including a voice coil suspended in the air gap, a diaphragm coupled to the voice coil and a compliant suspension member for suspending the voice coil within the air gap. The suspension member includes an electrically conductive biphasic member for providing an electrical connection between the voice coil and a circuit coupled to the frame.

Abstract: An audio speaker having a suspension system including a surround to support a diaphragm within a frame and to reduce non-pistonic motion of the diaphragm at several resonant frequencies is disclosed. More particularly, embodiments of the surround include a film that undulates in a peripheral direction around the diaphragm and includes several undulations above and below a radial gap between the diaphragm and the frame. Other embodiments are also described and claimed.

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 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 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.
