Abstract: A sound collecting apparatus capable of effectively suppressing sounds other than a target sound is provided. The sound collecting apparatus includes a plurality of microphones. A total number of effective microphone pairs in which a distance between two microphones is smaller than a distance D is larger than a total number of the plurality of microphones. The distance D is represented by D=c/2f, where the frequency of the target sound acquired from each of the plurality of microphones is f and sound velocity is c. When an angle formed by a straight line connecting two microphones configuring an effective microphone pair and a predetermined straight line is θ, the angles θ of all effective microphone pairs acquired from the plurality of microphones are different from each other.

Abstract: Embodiments of the disclosure generally include a method and apparatus for receiving and separating unwanted external noise from an audible input received from an audible source using an audible signal processing system that contains a plurality of audible signal sensing devices that are arranged and configured to detect an audible signal that is received from any position or angle within three dimensional space. The audible signal processing system is configured to analyze the received audible signals using a first signal processing technique that is able to separate unwanted low frequency range noise from the received audible signal and a second signal processing technique that is able to separate unwanted higher frequency range noise from the received audible signal. The audible signal processing system can then combine the signals processed by the first and second signal processing techniques to form a desired audible signal that has a high signal-to-noise ratio throughout the full speech range.

Abstract: A digital camera includes an optical assembly and image sensor for capturing still and/or video images and displaying the images on a screen. The camera includes three or more spaced apart microphones aligned with the optical assembly for capturing audio during image capture. At least two pairs of microphones are spaced apart along orthogonal directional axes for capturing left-right stereo sound in any camera orientation.

Abstract: A device and method for a vehicle to provide a bidirectional communication between the vehicle and at least one passerby. The device comprises a sensor for detecting a passersby near the vehicle and an array arranged on the vehicle and formed by a plurality of loudspeakers and a plurality of microphones for providing an acoustical beamforming focused in a predetermined region around the position of a detected passerby for the sending of acoustical signals to the passerby and for the receiving of acoustical information from the passerby. The device also has a computer-based recognition module coupled to the sensor and the array for recognizing gestures and/or acoustical messages from the passerby. An action of the vehicle, such as reproducing an acoustical signal and/or receiving a visual or acoustical message from the passerby, is performed based upon an identified passerby gesture and/or an identified acoustical message from the passerby.

Abstract: A conference system including a microphone array unit having a plurality of microphone capsules arranged in or on a board mountable on or in a ceiling of a conference room. The microphone array unit has a steerable beam and a maximum detection angle range. The conference system further includes a processing unit which is configured to receive the output signals of the microphone capsules and to steer the beam based on the received output signal of the microphone array unit. The processing unit is configured to control the microphone array to limit the detection angle range to exclude at least one predetermined exclusion sector in which a noise source is located.

Abstract: An omni-directional acoustic deflector includes an acoustically reflective body that has a truncated conical shape which includes a substantially conical outer surface that is configured to be disposed adjacent an acoustically radiating surface (e.g., a diaphragm) of an acoustic driver thereby to define an acoustic radiation path therebetween. The acoustically reflective body is profiled such that a cross-sectional area of the acoustic radiation path increases monotonically with respect to radial distance from a motion axis of the acoustic driver.
