The present technique relates to an earhole-wearable sound collection device, a signal processing device, and a sound collection method for realizing sound collection at a high S/N ratio, with noise influence being reduced not by a noise reduction process. In the earhole-wearable sound collection device, a microphone that collects emitted speech voice is provided in a space that is substantially sealed off from outside and connects to an ear canal of the wearer (the speaker). In a sound collection signal obtained through the ear canal, the emitted speech voice component is dominant over the noise component particularly at low frequencies. Therefore, the S/N ratio of an emitted speech voice collection signal can be improved by extracting the low-frequency component of the sound collection signal with the use of a LPF.

Earhole-wearable sound collection device, signal processing device, and sound collection method

An information processing apparatus () includes a sound source extraction unit () and a mapping processing unit (). The sound source extraction unit () extracts one or more audio data (AD) corresponding to different sound sources from audio content (AC). The mapping processing unit () selects, for each audio data (AD), one or more display units () to serve as mapping destinations of the audio data (AD) from one or more combinable display units () including a sound producing mechanism.

Information processing apparatus, information processing method, and information processing program

There is provided an output apparatus that includes one or more display panels, a support member, and an actuator section. The one or more display panels are capable of displaying an image. The support member includes a support portion for supporting the respective one or more display panels. The actuator section is disposed between the one or more display panels and the support portion and vibrates the respective one or more display panels. In this output apparatus, an image is output by the one or more display panels. Further, the actuator section is disposed between the display panels and the support portion of the support member, and the display panels are vibrated.

Disclosed is a signal processing apparatus including a surrounding sound signal acquisition unit, a NC (Noise Canceling) signal generation part, a cooped-up feeling elimination signal generation part, and an addition part. The surrounding sound signal acquisition unit collects a surrounding sound to generate a surrounding sound signal. The NC signal generation part generates a noise canceling signal from the surrounding sound signal. The cooped-up feeling elimination signal generation part generates a cooped-up feeling elimination signal from the surrounding sound signal. The addition part adds together the generated noise canceling signal and the cooped-up feeling elimination signal at a prescribed ratio.

Acoustic signal processing device, acoustic signal processing method, and program

Provided is an information processing apparatus including a sensor, an actuator, a vibration control circuit, a transmission circuit, and a reception circuit. The sensor detects vibration of a control target. The actuator provides vibration control of the control target. The vibration control circuit generates a drive signal for the vibration control for the actuator according to an output signal of the sensor, and outputs the generated drive signal to the actuator. The transmission circuit modulates transmission data to produce a transmission signal, and synthesizes the modulated transmission signal to produce the drive signal for the vibration control that is to be outputted to the actuator. The reception circuit extracts a reception signal from the output signal of the sensor, and demodulates the extracted reception signal to produce reception data.

A noise cancellation signal generation device includes a reference sensor; a speaker that outputs sound based on a noise cancellation signal a memory that records second information for obtaining a filter coefficient of a noise cancellation filter calculated on the basis of first information obtained in consideration of a change in a relative position between the speaker and a noise cancellation point and a noise cancellation processor that acquires the second information from the memory using a signal acquired by a sensor, and generates the noise cancellation signal on the basis of the filter coefficient obtained from the acquired second information and a reference signal acquired by the reference sensor.

Noise cancellation signal generation device and method thereof

Provided is an acoustic reproduction system capable of setting a sound image localization service area at an arbitrary position even in a case where a sound production direction of a directional sound cannot be changed. An acoustic reproduction system according to the present technology includes a sound producing device that emits a directional sound and a sound reflector positioned between a viewer and a viewing target by the viewer and having a sound reflecting surface that reflects the directional sound emitted by the sound producing device.

The reflector has an elliptical reflection surface in at least a part of the reflection surface. With this configuration, the sound output from the speaker device disposed outside the region of the projection surface is reflected on the reflector, and a sound image thereof is localized within the region of the projection surface, whereby it is possible to bring a display position of a video into alignment with an output position of the sound. Thus, a comfortable viewing state can be ensured for a viewer.

The earhole open/close state is set for each user. The earhole open/close state can be switched depending on the type of application or content to be played, ambient noise level, user behavior, position information, or the like.
