摘要： The technology of this application relates to a laser microphone, including a diaphragm, a laser device, a control circuit, a self-mixing signal obtaining apparatus, and a signal processing circuit. The laser device is configured to emit light to the diaphragm and receive a feedback light signal from the diaphragm, and the feedback light signal interferes with laser in a resonant cavity of the laser device to obtain a self-mixing light signal. A distance between the laser device and the diaphragm ranges from 30 to 300 m. The control circuit is connected to the laser device, and is configured to drive and control the laser device to emit light. The self-mixing signal obtaining apparatus is connected to the laser device, and is configured to obtain a target voltage signal related to the self-mixing light signal.

摘要： An electronic device having hearing aid capability is disclosed. The electronic device includes a linear resonance actuator (LRA). The LRA is configured to produce both vibrations and a hearing aid compatible magnetic field. A processor coupled to the LRA is operable to control the LRA to generate a magnetic field for inductively coupling the electronic device to a hearing aid when a hearing aid compatibility (HAC) mode is enabled, wherein the generated magnetic field is encoded with audio information which corresponds to an audio signal.

摘要： A method for generating an auditory environment for a user may include receiving a signal representing an ambient auditory environment of the user, processing the signal using a microprocessor to identify at least one of a plurality of types of sounds in the ambient auditory environment, receiving user preferences corresponding to each of the plurality of types of sounds, modifying the signal for each type of sound in the ambient auditory environment based on the corresponding user preference, and outputting the modified signal to at least one speaker to generate the auditory environment for the user. A system may include a wearable device having speakers, microphones, and various other sensors to detect a noise context. A microprocessor processes ambient sounds and generates modified audio signals using attenuation, amplification, cancellation, and/or equalization based on user preferences associated with particular types of sounds.

摘要： A user interface apparatus using a speaker to control device operations by utilizing a speaker and a method thereof are provided. The user interface apparatus includes a user input pad that forms at least a portion of the exterior of a speaker and is configured to generate an impact sound wave based on an external impact An impact sound wave recognizer is configured to receive feedback of an output signal output via the speaker and separate a reverse current signal due to the impact sound wave included in the feedback signal. In addition, a controller is configured to analyze a waveform of the reverse current signal separated by the impact sound wave recognizer to recognize a user input pattern, and output a control signal that corresponds to the recognized user input pattern. The device operations of various devices may be controlled by tapping or flicking the exterior of a speaker.

摘要： A personal safety system detects imminent danger or other event of interest and then modifies a sound panorama to focus a user's attention towards the direction of the danger or other event of interest. The personal safety system may isolate sounds originating from the direction of the danger or other event of interest, collapse the sound panorama towards the direction of the danger or other event of interest, or compress the sound panorama to align with the direction of the danger or other event of interest. The personal safety system may be integrated into an automobile or a wearable system physically attached to the user. Advantageously, the attention of the user may be drawn towards imminent danger or other events of interest without introducing additional sensory information to the user, thereby reducing the likelihood of startling or distracting the user.
