摘要： A device comprising: an acoustic transducer comprising a phased array of transducer elements, wherein the transducer elements are arranged in a circular pattern; one or more processors; and a computer-readable medium storing instructions that, when executed by the one or more processors, cause the acoustic transducer to perform functions comprising: transmitting a focused ultrasound wave from the acoustic transducer into a medium to form (i) an ultrasound intensity well within the medium that exhibits a first range of acoustic pressure and (ii) a surrounding region of the medium that surrounds the ultrasound intensity well and exhibits a second range of acoustic pressure that exceeds the first range of acoustic pressure; and interacting an object within the ultrasound intensity well with the focused ultrasound wave; wherein said phased array is configured to electronically focus or steer said ultrasound wave upon various portions of said medium and/or said object, characterized in that, transmitting the focused ultrasound wave into the medium comprises transmitting the focused ultrasound wave in one direction of propagation away from the acoustic transducer into the medium.

摘要： Problem
An object is to provide an acoustic pressure estimation system capable of improving interpolation accuracy, and an acoustic pressure estimation method and an acoustic pressure estimation program of the acoustic pressure estimation system.
Solving Means
An acoustic pressure estimation system 1 includes, a plurality of sensors 3 provided in a circumferential direction and configured to measure acoustic pressure, a Fourier transform unit 5 configured to perform a Fourier transform on a discrete signal and derive a Fourier coefficient with, as the discrete signal, a signal representing a measurement value of each of the sensors 3 as a function of a position in the circumferential direction, and an inverse Fourier transform unit 6 configured to perform an inverse Fourier transform on a predetermined position on a circumference by using the Fourier coefficient, and derive acoustic pressure in the predetermined position.

摘要： The present technology relates to an audio output controller, an audio output control method, and a program that can improve sound quality.
An audio output controller includes multiple speaker units installed so as to face different directions, outputs measurement sound from at least one speaker unit of the multiple speaker units, and controls a gain of the speaker unit on the basis of a reverberation characteristic when the measurement sound is measured by a microphone in a predetermined position. Measurement sound output from a speaker unit installed in another audio output controller is measured by the microphone. Alternatively, measurement sound output from an installed speaker unit is measured by the microphone. The present technology can be applied to a wireless speakers, for example.

摘要： The invention relates to a device for separating parts in a production process comprising a sound-producing device (19) for producing sound waves and a base, which is mechanically decoupled from the sound-producing device and forms a separating surface (14) and which is arranged and designed in such a way that the sound waves emitted by the sound-producing device (19) move at least part of the separating surface (14) in such a way that parts lying thereon are excited to move. The invention further relates to a corresponding method.

摘要： Provided are method and apparatus for evaluating audio device for evaluating performance of an audio device by inputting into the audio device an audio signal having a waveform in which a plurality of waves with different frequency components are superimposed, comparing the sound waveform before the input and the sound waveform after the input, and finding the degree of conformity therebetween. An audio device of the present invention is characterized in that, with sound field correction as a precondition, low-pitch ranges can be reproduced by using numerous small-diameter speakers, a single one of which is insufficient to reproduce low-pitch ranges despite good group delay characteristic, and outstanding waveform reproducibility can be achieved by covering the periphery of the speakers with sound-absorbent material so as to remove noise emitted by surfaces other than the front surface of cone paper.
