Abstract:
A method performed a local device that is communicatively coupled with several remote devices, the method includes: receiving, from each remote device with which the local device is engaged in a communication session, an input audio stream; receiving, for each remote device, a set parameters; determining, for each input audio stream, whether the input audio stream is to be 1) rendered individually or 2) rendered as a mix of input audio streams based on the set of parameters; for each input audio stream that is determined to be rendered individually, spatially rendering the input audio stream as an individual virtual sound source that contains only that input audio stream; and for input audio streams that are determined to be rendered as the mix of input audio streams, spatially rendering the mix of input audio streams as a single virtual sound source that contains the mix of input audio streams.
Abstract:
Disclosed are techniques for a multimedia device with audio and video capturing capability to identify an audio device based on acoustic playback signal if the audio device cannot be identified from captured video. The multimedia device may assemble a list of candidate audio devices that are a possible match for the observed audio device from a database of previously recognized audio devices and may transmit commands to the candidate audio devices to play acoustic identification signals. The acoustic identification signals may be audible sound or ultrasonic tone sequences with embedded identification information unique to each audio device. The multimedia device may record and analyze the acoustic identification signals received from any of the candidate audio devices to construct metrics to select the most likely candidate for the observed audio device. The metrics may include time of flight, direction of arrival, received amplitude, direct-to-reverberant ratio (DRR) of the acoustic identification signals.
Abstract:
An electronic device has a housing that forms an exterior surface of the electronic device. An array of actuators is coupled to the housing and is operable to move the housing in order to produce sound waves and/or haptic output via the exterior surface. In this way, less space is consumed by acoustic and haptic devices as compared to similar conventional devices, thereby allowing for thinner electronic devices and/or room for other components within the housing. The actuators may be operable to move different regions of the housing to produce sound waves and/or haptic output within different frequency ranges.
Abstract:
An electronic device can include a housing defining an aperture and a display positioned in the aperture. The display and the housing can define an internal volume in which a speaker assembly is positioned. The speaker assembly can include a speaker module and a speaker enclosure in fluid communication, with the speaker enclosure at least partially defining a speaker volume.
Abstract:
An electronic device having several speaker modules that are acoustically in-phase and mechanically out-of-phase is disclosed. Embodiments include a pair of speaker modules mounted at respective ends of a lateral link, and the lateral link may be supported relative to a housing of the electronic device. The speaker modules may receive a same audio signal, and the audio signal may drive a first voicecoil in a first direction and a second voicecoil in a second direction. Accordingly, the speaker modules may be driven in mechanically different directions by the same audio signal, such that reactive forces cancel and/or mechanical energy is dissipate in the lateral link between the speaker modules. 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:
An electronic device may have a metal housing. The metal housing may have an upper housing in which a component such as a display is mounted and a lower housing in which a component such as a keyboard is mounted. Hinges may be used to mount the upper housing to the lower housing for rotation about a rotational axis. A slot-shaped opening may separate the upper and lower housing. A flexible printed circuit with ground traces may bisect the slot-shaped opening to form first and second slots. Cavity antennas may be aligned with the slots. Each cavity antenna may include a hollow carrier with a pair of speakers. The speakers may have ports that emit sound through aligned openings in the lower housing. Conductive gaskets surrounding the ports may acoustically seal the speaker ports while shorting the cavity antenna to the lower housing.

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.
