    Abstract: An apparatus for measuring a plurality of loudspeakers arranged at different positions includes a generator of a test signal for a loudspeaker; a microphone device configured for receiving a plurality of different sound signals in response to one or more loudspeaker signals emitted by one of the loudspeakers in response to the test signal; a controller for controlling emissions of the loudspeaker signals by the loudspeakers and for handling the different sound signals so that a set of sound signals recorded by the microphone device is associated with each loudspeaker in response to the test signal; and an evaluator for evaluating the set of sound signals for each loudspeaker to determine at least one loudspeaker characteristic for each loudspeaker and for indicating a loudspeaker state using the at least one loudspeaker characteristic. This scheme allows automatic, efficient and accurate measurement of loudspeakers arranged in a three-dimensional configuration.

    Abstract: An audio speaker has at least one transducer for converting electrical signals into mechanical motion. There is a planar sound producing structure that has a first face and a second face. A mechanical connection connects the at least one transducer to the sound producing structure, such that mechanical motion produced by the at least one transducer induces the sound producing structure to vibrate and produces sound from the first face and the second face. A deflector is interposed between the at least one transducer and the sound producing structure. The deflector is adjacent to the second face of the sound producing structure and reflects the produced sound from the second face of the sound producing structure to a listening area forward of the first face.

    Abstract: An acoustic apparatus includes at least two speakers, each of the speakers having a sound producing direction directed to a corresponding ear of left and right ears of a listener; and an enclosure covering a back portion of a corresponding speaker of the speakers. An opening to open the enclosure is provided at a position further away from the corresponding ear than the corresponding speaker of the speakers. An opening area of the opening is greater than or equal to an effective vibration area of each of the speakers.

    Abstract: A control method and an electronic device are provided. The electronic device generates vibration when performing at least one function. The electronic device includes an acceleration sensor and a feedback circuit. The acceleration sensor is configured to output acceleration data, and the feedback circuit is configured to collect and feed back data related to the vibration. The electronic device obtains, based on a variation of a magnitude of the obtained acceleration data and interference data, a variation obtained after data processing, and performs action recognition. The electronic device performs a corresponding function based on a recognition result, or controls a second electronic device to perform a corresponding function.

    Abstract: A method for directional sound capture. The method includes capturing, using a camera device, a sequence of images of a scene comprising a light source attached to a sound source object, detecting, by a hardware processor based on a pattern of local light change across the sequence of images, the light source in the scene, determining a direction of the sound source object by at least determining a location of the light source in at least one image of the sequence of images, transmitting, to a direction control device coupled to a microphone, a control signal to direct a sensitivity direction of the microphone towards the sound source object, and capturing, using the microphone and in response to directing the sensitivity direction of the microphone towards the sound source object, the sound emitted from the sound source object.
