Abstract: A presence of a person within a camera field of view of an electronic device is determined by digitally processing images captured by a camera. A position of a body member of the person with respect to the electronic device is also computed by digitally processing the camera captured images. A crosstalk cancellation (XTC) signal is adjusted based on the computed position of the body member. Adjusting the XTC signal includes adjusting a first predetermined model location, which includes a location at which a user should be in order to achieve a desired virtual acoustics effect. Processing program audio based on the adjusted XTC signal, to generate audio signals that drive speakers. Other aspects are also described and claimed.

Abstract: A low Z linear vibrator is described well suited for use in small form factor portable devices such as a smartphone. The low Z vibrator can be configured to include a beam structure that can be attached to a vibratory mass and a low profile actuator. The low profile actuator can cause the vibratory mass to oscillate in a well-defined and predictable manner.

Abstract: Systems and methods for enhancing performance of a microphone are disclosed. An airflow control system may include a block-shaped structure and an airflow impedance element residing within a cavity of the block-shaped structure. The airflow impedance element may be formed by filling the cavity with a plurality of pre-processed airflow impedance elements and sintering these elements, and may include a plurality of non-linear pathways. The plurality non-linear pathways may both impede airflow therethrough (e.g., when a force exerted by the airflow exceeds a predetermined amount) and pass sound that may match a frequency response of a microphone without substantially affecting the amplitude and frequency characteristics of the sound.

Abstract: Systems and methods for retaining a microphone using a microphone boot are disclosed. The microphone boot may include a sound channeling structure for receiving and delivering sound, and a microphone retaining block for retaining a microphone and passing the sound to the microphone. The sound channeling structure may be secured to a housing of an electronic device. The sound channeling structure may include a sound tube and a hooking component that may be insertable into a tunnel and a slot, respectively, of the microphone retaining block. The sound tube may deliver the sound into the tunnel for passing to the microphone. The hooking component may lock into the slot to secure the sound channeling structure to the microphone retaining block. Thus, the microphone boot may be tightly sealed to prevent leakage of the sound, and may fix the microphone within the electronic device even in the presence of external force.

Abstract: Systems and methods for controlling airflow into an electronic device are disclosed. An airflow control system may include an airflow impedance plate having one or more airflow impeding features. The airflow impedance plate may be a passive device that may be configured to impede forceful airflow therethrough and also allow sound to pass therethrough.

Abstract: An electronic device can include different components providing different functionality. Some electronic devices can include a proximity sensor for determining when a user's face is near the device. The sensor can include an emitter and a detector that are separated by a foam block to limit cross-talk between the emitter and detector. A sheet can be placed over the foam block to define openings for each of the emitter and detector. Some electronic devices can also include a camera. A glass cover secured to the device enclosure can protect the camera. To improve an adhesive bond between the glass cover and a metal enclosure, an ink layer can be placed between an adhesive and the glass. In addition, the camera or another component may need to be grounded to ensure proper operation. During assembly, however, the position of the camera can shift due to closing an enclosure. A grounding assembly that maintains contact with the camera in its initial and final positions can be provided.
