Abstract: The voice control device includes a sound source signal input unit, a frequency determination unit, a band controller, a sound image controller, and a voice output unit. The sound source signal input unit inputs a sound source signal of content from a sound source. The frequency determination unit determines a cutoff frequency. The band controller acquires a high frequency signal in a frequency band equal to or higher than the cutoff frequency and a low frequency signal in a frequency band equal to or lower than the cutoff frequency, from the sound source signal of the content. The sound image controller generates a plurality of sound image control signals for controlling sound images of the plurality of speakers, by controlling at least one of a phase and a sound pressure level of the high frequency signal. The voice output unit outputs the low frequency signal to a first speaker, and outputs the plurality of sound image control signals to a second speaker composed of a plurality of speakers.

Abstract: In the noise reduction device, the sound receiver receives a noise signal acquired from the microphone. The sound source input unit receives an input of a sound source signal from a sound source. The sound adjuster changes the intensity of the sound source signal relative to the intensity of the noise signal. The control sound generator generates a control sound signal that reduces the noise signal. The control unit controls the change of the intensity of the sound source signal and the generation of the control sound signal. The sound output outputs the control sound signal to the speaker. The sound output outputs to the speaker the sound source signal at the intensity changed by the sound adjuster.

Abstract: A selective laser sintering method reduces a warping deformation of a three-dimensional shaped object, the warping deformation being due to the scanning of a light beam. The manufacturing method is a method for manufacturing a three-dimensional shaped object by alternate repetition of a powder-layer forming and a solidified-layer forming, wherein a scanning of the light irradiation is divided into light beam-scannings “A” and “B”, the light beam-scanning “A” being for the light irradiation of a peripheral portion corresponding to a periphery of the three-dimensional shaped object, and the light beam-scanning “B” being for the light irradiation of an internal portion corresponding to a region of the three-dimensional shaped object, the region being located inside the periphery. In particular, the peripheral portion is subjected to a discontinuous light beam-irradiation in the light beam-scanning “A” such that an irradiation path of the light beam is divided into a plurality of sub-irradiation paths.
