A microelectromechanical system (MEMS) sensor device includes a package housing having a top member, bottom member, and a spacer coupled the top member to the bottom member, defining a cavity. At least one sensor circuit and a MEMS sensor disposed within the cavity of the package housing. A first opening formed on the package housing a control device embedded within the package housing is electrically coupled to the sensor circuit and is controlled to tune the MEMS sensor from a directional mode to an omni-directional mode.

Disclosed are an electronic device and a control method. The electronic device comprises a communication interface for communicating with an external apparatus in a UWB manner, a microphone, a camera, a sensor, a display, and a processor, wherein the processor obtains distance information and angle information with respect to the external apparatus, on the basis of data received from the external apparatus, obtains photographing direction information, on the basis of a detected direction of the camera, identifies the external apparatus, on the basis of the acquired photographing direction information, distance information, and angle information, controls the microphone or communication interface to acquire an audio signal, on the basis of a distance from the external apparatus, and controls the display to display a UI indicating the amplitude of the acquired audio signal, together with a displayed image.

A conference gallery view intelligence system determines regions of interest for display within views of conferencing software based on input streams received from devices within a conference room during a conference. Conference participants are detected in the conference room based on an input video stream received from a video capture device. A direction of audio from the conference participants is determined based on an input audio stream received from a multi-directional audio capture device. A conversational context within the conference room is then determined based on the direction of the audio and locations of the one or more conference participants in the conference room. A region of interest to output within conferencing software is determined based on the conversational context, and the region of interest is output for display within a view of the conferencing software.

A case for a portable electronic device includes an enclosed, elongated space extending within the case from an opening in an interior surface of the case. The opening corresponds to the location of a microphone in the device. The enclosed space is tapered to an increasingly smaller cross-section as it extends away from the opening. A first edge of the enclosed space aligns along most of its length with an exterior surface of the case. A screen covers a second opening in the exterior surface of the case along the first edge of the elongated space and provides an acoustic resistance between the elongated space and air outside the case through the second opening. A gasket located at the first opening couples the elongated space to the microphone of the electronic device.

An audio session management method may involve: determining, by an audio session manager, one or more first media engine capabilities of a first media engine of a first smart audio device, the first media engine being configured for managing one or more audio media streams received by the first smart audio device and for performing first smart audio device signal processing for the one or more audio media streams according to a first media engine sample clock; receiving, by the audio session manager and via a first application communication link, first application control signals from the first application; and controlling the first smart audio device according to the first media engine capabilities, by the audio session manager, via first audio session management control signals transmitted to the first smart audio device via a first smart audio device communication link and without reference to the first media engine sample clock.

A hearing apparatus includes: a receiving unit configured to obtain a first speech signal; a processor configured to provide of an electrical output signal based on the first speech signal; and a receiver for providing an audio output signal based on the electrical output signal; wherein the hearing apparatus is configured to determine a first word count of the first speech signal, and update a total word count based on the first word count.

Image data relating to real-world objects or persons is collected from a scene while collecting audio data relating to the real-world objects or persons from the same scene. The audio data is used to derive sound objects corresponding to the real-world objects or persons. The image data is used to derive video objects corresponding to the real-world objects or persons. Based on the sound objects and the video objects, candidate salient objects are generated. A salient object is selected from among the candidate salient objects. Perceptual enhancement operations are performed on the selected salient object.

A directional microphone system includes a microphone assembly designed to be mounted from a ceiling or other raised surface through a reeling mechanism used to deploy the microphone assembly to a lowered position, preferably just above eye level of a speaker. The microphone assembly includes an outer housing encapsulating multiple audio detection elements or capsules which are specifically angled relative to each other and the horizontal in order to optimize targeted audio reception. With a preferred arrangement, three audio detection (microphone) elements are secured through with a wishbone frame mounted in the outer housing, with each element being at about a 60° angle to the horizontal to provide enhanced horizontal coverage.

An audio recording apparatus provided with a heat radiation fan comprises at least one processor and/or circuit configured to function as following units: an acquiring unit configured to acquire a type of microphone used to record audio; a control unit configured to control a rotation frequency for driving the heat radiation fan; and a recording unit configured to record audio acquired by the used microphone, wherein the control unit changes the rotation frequency of the heat radiation fan according to the type of the used microphone acquired by the acquiring unit.

One example discloses an apparatus for voice communication, including: a first wireless device including a first pressure sensor having a first acoustical profile and configured to capture a first set of acoustic energy within a time window; wherein the first wireless device includes a near-field magnetic induction (NFMI) signal input; wherein the first wireless device includes a processing element configured to: receive, through the NFMI signal input, a second set of acoustic energy captured by a second pressure sensor, having a second acoustical profile, within a second wireless device and within the time window; apply a signal enhancement technique to the first and second sets of acoustic energy based on the first and second acoustical profiles; and output an enhanced voice signal based on applying the signal enhancement.
