摘要： 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.

摘要： 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.

摘要： The present technology relates to a noise cancellation signal generation device, method, and program capable of improving noise reduction performance.
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. The present technology can be applied to an ANC system.
