摘要： A sound source separation device includes a first microphone that picks up a first voice, a second microphone that picks up a second voice, a first crosstalk canceller that removes, from a voice signal of the first microphone, first crosstalk caused when the second voice is picked up by the first microphone, and a second crosstalk canceller that removes, from a voice signal of the second microphone, second crosstalk caused when the first voice is picked up by the second microphone. The first crosstalk canceller uses a voice signal in which the second crosstalk is removed from the voice signal of the second microphone to estimate and calculate a first interference signal indicative of a degree of the first crosstalk, and to remove the calculated first interference signal from the voice signal of the first microphone. The second crosstalk canceller uses a voice signal in which the first crosstalk is removed from the voice signal of the first microphone to estimate and calculate a second interference signal indicative of a degree of the second crosstalk, and to remove the calculated second interference signal from the voice signal of the second microphone.

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.

摘要： Systems and methods for transducer volume bias control. The methods involve: obtaining an audio signal that is to be output from first and second transducers of an electronic device; and dynamically changing spectral content of the audio signal to at least one of the first and second transducers as a transducer volume level increases and decreases. The first transducer is disposed on a first side of the electronic device. The second transducer is disposed on a second side that is different than the first side of the electronic device. The first and second transducers have imbalanced capabilities.

摘要： Embodiments are directed to upward-firing speakers that reflect sound off a ceiling to a listening location at a distance from a speaker. The reflected sound provides height cues to reproduce audio objects that have overhead audio components. A virtual height filter based on a directional hearing model is applied to the upward-firing driver signal to improve the perception of height for audio signals transmitted by the virtual height speaker to provide optimum reproduction of the overhead reflected sound. The upward firing driver is tilted at an inclination angle of approximately 20 degrees to the horizontal axis of the speaker and separate height and direct terminal connections are provided to interface to an adaptive audio rendering system.

摘要： A system is provided that produces haptic effects. The system receives an audio signal that includes a low-frequency effects audio signal. The system further extracts the low-frequency effects audio signal from the audio signal. The system further converts the low-frequency effects audio signal into a haptic signal by shifting frequencies of the low-frequency effects audio signal to frequencies within a target frequency range of a haptic output device. The system further sends the haptic signal to the haptic output device, where the haptic signal causes the haptic output device to output one or more haptic effects.

摘要： Embodiments are directed to speakers and circuits that reflect sound off a wall surface (114) to a listening location at a distance from a speaker. The reflected sound (103) provides direct audio cues to reproduce audio objects that have direct audio components without the need for direct firing speakers. The speaker comprises sideward firing drivers (108) to reflect sound off of the wall surface (114) and represents a virtual direct speaker (116). A virtual direct filter is applied to the sideward-firing driver signal to improve the perception of direct audio transmitted by the sideward firing speaker (108) to provide optimum reproduction of the reflected sound. The virtual direct filter may be incorporated as part of a crossover circuit that separates the full band and sends high frequency sound to the sideward-firing driver (108).

摘要： A range switching earphone includes an earphone housing, a low pitch loudspeaker, a high pitch loudspeaker, a circuit adaptation module, and a control unit. The low pitch loudspeaker, the high pitch loudspeaker, and the circuit adaptation module are in the earphone housing. The circuit adaptation module is electrically connected to the low pitch loudspeaker and the high pitch loudspeaker. The control unit is connected to the circuit adaptation module for switching on or off of the high pitch loudspeaker or for switching filtering modes of a filtering unit in the circuit adaptation module. Therefore, different frequency response can be achieved with the same earphone, thereby satisfying requirements or tastes of users for listening music of different styles or in different circumstances. Thus, both classical music lovers and game players who want to have an immersed sense can all be satisfied by the range switching earphone.
