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 assembly support member that is separate from the magnet assembly. A voice coil extends from the bottom face of the sound radiating surface.

Abstract: An electronic device for buzz reduction is described. The electronic device is to be used with a speaker driver that is built onto an enclosure and is to be driven by an audio signal which could cause the enclosure to produce buzz. The electronic device includes a filter that is to attenuate a frequency component of the audio signal before driving the speaker driver. The electronic device also includes a controller that is to configure the filter to attenuate the frequency component of the audio signal in response to determining that strength of the audio signal at the frequency component exceeds a threshold. Other embodiments are also described and claimed.

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: Systems and methods for reducing the effects of stray magnetic flux are provided. For example, an electronic device can employ the system and can include a first audio component configured to have a first acoustic phase and a first magnetic phase. The electronic device can also include a second audio component configured to have the first acoustic phase and a second magnetic phase that is opposite the first magnetic phase. The first audio component can be positioned with respect to the second audio component, such that any stray magnetic flux from the first audio component enters the second audio component during operation of the first and second audio components.

Abstract: A first electronic device includes a first coil that is operative in at least two modes. In a first mode, the first coil may be utilized to moves a membrane to produce one or more sound waves, register movement of a membrane to detect one or more sound waves, or generates one or more haptic outputs. In the second mode, the first coil may be used to inductively transmit power to and/or inductively receive power from a second coil included in a second electronic device. In various cases, the second coil may be a dedicated inductive power transmission coil. In other cases, the second coil may be capable of multimode operation similar to the first coil.

Abstract: An electronic device may be provided with a microphone in a microphone port. A shield may cover a microelectromechanical systems microphone device on a microphone substrate. An opening in the microphone substrate may form a sound port for the microphone. The microphone port may be formed by perforations in the microphone substrate or other layers such as a flexible printed circuit layer, a sheet metal layer, a layer of adhesive, a flexible polymer carrier layer in an adhesive tape, or an electronic device housing. The perforations may be sufficiently small to help resist the intrusions of foreign material such as liquid and dirt into the sound port of the microphone. Larger openings may be formed in other structures such as an electronic device housing. The larger openings may serve as sound passageways for the microphone port while being sufficiently large to resist clogging.

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.
