Abstract: An additively manufactured component has an additively manufactured substrate and an inclusion. The substrate has a first region and a second region defining a first contour and a second contour, respectively. One or both of the first contour and the second contour is non-planar. The inclusion is positioned between the first region and the second region. The inclusion has a first major surface conforming to the first contour. The inclusion also has a second major surface. The second major surface can conform to the second contour. The inclusion can be a cavity, and the substrate can enclose the cavity or the cavity can be in open communication with an environment surrounding the substrate. The inclusion can be a member or an assembly of plural members. Modules and electronic devices incorporating an additively manufactured component also are described.

Abstract: In one aspect herein, a pre-processor receives audio signals for a conference call from individual callers, each of the audio signals associated with corresponding metadata, analyzes the metadata, and associates each of the audio signals with a spatial position in a virtual representation of the conference call based on the analyzation of the metadata. A spatial arrangement processor generates a binaural room impulse response associated with the spatial position of each of the audio signals to filter the received audio signals to account for the spatial position associated with each of the audio signals and to account for the effect of the virtual representation of the conference call. A head-tracking controller tracks an orientation of a listener's head using a headset. A binaural renderer produces multi-channel audio data for playback on the headset according to the orientation of the listener's head and the binaural room impulse response associated with the spatial position of each of the audio signals.

Abstract: A portable electronic device including an enclosure having an enclosure wall that forms an interior chamber. A speaker module is positioned within the interior chamber and includes a speaker and a module wall forming a back volume chamber of the speaker. The back volume chamber includes an acoustic vent port formed through the module wall to acoustically couple the back volume chamber to the interior chamber. The device further including an electromechanical valve for regulating the acoustic coupling of the back volume chamber to the interior chamber. The electromechanical valve is operable to transition between an open configuration in which the acoustic vent port is open to the interior chamber and a closed configuration in which the acoustic vent port is closed off from the interior chamber.

Abstract: A micro speaker assembly including a micro speaker having a top plate, a bottom plate parallel to the top plate, a magnet assembly coupled to one of the top plate or the bottom plate, a compliant member positioned between the magnet assembly and the top plate or the bottom plate, the compliant member operable to be displaced in response to an acoustic input, and a voice coil coupled to the compliant member. The assembly further including an optical sensor coupled to the micro speaker, the optical sensor having a light emitter and a light detector, the light emitter and the light detector being fixedly coupled to the top plate or the bottom plate, and the optical sensor being operable to produce a displacement signal corresponding to a displacement of the compliant member and a temperature signal corresponding to a temperature of the magnet assembly.
