摘要： There is described a method for synchronizing a viewer-effect signal of a media content with a media signal of the media content. The method generally has: capturing an audio portion of the media signal from a surrounding environment using a microphone; obtaining a fingerprint from the captured audio portion of the media signal; from reference fingerprints associated with reference time positions of at least a reference media content, identifying a time position of the media content corresponding to the obtained fingerprint; obtaining the viewer-effect signal associated with the identified time position of the media content; and outputting the viewer-effect signal synchronized with the media signal using the identified time position of the media content for producing an effect to a viewer in synchronization with the media signal of the media content.

摘要： An electronic device includes a communicator, a sound outputter, and a controller. The communicator communicates with a terminal of a human speaker and communicates with another electronic device that outputs at least one of a predetermined auditory effect or a predetermined visual effect. The sound outputter outputs an audio signal of the human speaker that the communicator receives from the terminal of the human speaker as sound of the human speaker. The controller sets a volume of the sound that the sound outputter outputs. The controller controls the other electronic device to output at least one of the auditory effect or the visual effect when a level of the sound at a position of a candidate that is to be a recipient of the sound is changed at the terminal of the human speaker.

摘要： A set-top box, integrating a speaker having an acoustic box. At least two first loudspeakers and one second loudspeaker are integrated. The two first loudspeakers are positioned at the front and on each side of the acoustic box. A central axis (X2) of a membrane of the second loudspeaker is a vertical axis. The set-top box includes, in addition, a main electronic board having a decoding module and an audio module. The second loudspeaker and the main electronic board are positioned on either side and extending successively along a length (L′) of the set-top box which is perpendicular to a front-to-rear axis of the acoustic box.

摘要： 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.

摘要： A method for feedforward noise cancellation in an enclosed space within a structure is provided. The method comprises placing a microphone array inside an inner surface of the enclosed space and conducting modal testing on an outside surface of the enclosed space, wherein the modal testing comprises multiple incoherent noise sources corresponding to locations of microphones in the microphone array. Noise generated by the modal testing is processed to create a number of acoustic mathematical models of the enclosed space. In response to incoherent noise within the enclosed space, a noise canceling signal is generated according to an output of the mathematical models.

摘要： A technique suitable when an air floating video is used as a non-contact user interface is provided. An air floating video display apparatus includes: a sensor for detecting a state of operation including a position of a hand finger of a user with respect to an air region including a plane of the air floating video or an object displayed on the plane; and a fingertip tactile sense generator which generates texture of a sense of touch on the hand finger by forming, based on information detected by the sensor, sound pressure based on an ultrasonic wave in vicinity of a position of the hand finger.

摘要： The invention relates to a system for generating sound waves for at least two separate zones of a single space. The system includes, for each zone of said space: at least one array of high-frequency loudspeakers forming a directional sound wave; and at least one low-frequency loudspeaker. The system also comprises means for audio processing of the signals transmitted to the loudspeakers, which means control at least one loudspeaker to generate destructive sound waves in at least one zone of said space and to obtain distinct sound contents in said at least two distinct zones of said space. To do this, the audio-processing means control each low-frequency loudspeaker individually and each array of high-frequency loudspeaker mutually in order to generate the destructive sound waves.

摘要： A sound source is located by recording a sound generated by the sound source by several microphones arranged on a vehicle. A direction or position of the sound source is determined relative to the vehicle using a delay in the reception of the sound at one of the microphones in relation to another of the microphones.

摘要： The image detecting apparatus including an image capturing device, a microphone array and a processing circuit is provided. The image capturing device captures an image. The microphone array detects a voice source. The processing circuit performs a voice activity detection on a first number of voice signals captured by the microphone devices to determine whether the voice source is a preset type voice. The processing circuit performs a beamforming operation on a second number of voice signals captured by the microphone devices to generate a region of interest (ROI) setting signal when the voice source is the preset type voice. The ROI setting signal indicates a location of the voice source in the image. The processing circuit performs an image detecting operation on a ROI image. The ROI image is determined according to the image and the ROI setting signal. The first number is smaller than the second number.
