Abstract: An area reproduction system includes a speaker array with a plurality of speakers arranged side by side, receives an input of a reproduced sound, collects an environmental sound in a non-reproduction area different from a reproduction area in which a sound beam of the reproduced sound is emitted, acquires noise included in the environmental sound and a leakage sound leaking to the non-reproduction area, generates a masking sound having a sound pressure higher than that of the leakage sound based on the frequency characteristics of the sound pressures of the noise and the leakage sound, adjusts the directivity of the masking sound to be output from each of the plurality of speakers in such a manner that the sound beam of the masking sound is emitted to the non-reproduction area while avoiding a listener, and causes each of the plurality of speakers to output the adjusted masking sound.

Abstract: A sound reproduction device is configured to store a head of a user and reproduce sound. The sound reproduction device includes: a headrest portion; a partition portion attached to the headrest portion so as to protrude forward relative to a front surface of the headrest portion; a speaker disposed in the partition portion; and a sound absorbing structure provided in at least a part of the inner surface of the partition portion excluding a region corresponding to an output surface of the speaker.

Abstract: A display apparatus includes: a first lens barrel in a shape of a bottomed barrel and including, as a bottom portion, a first display device that displays a first image; a second lens barrel in a shape of a bottomed barrel and including, as a bottom portion, a second display device that displays a second image; a support member that supports the first and second lens barrels; and an eye cup that is in a barrel shape and is provided at an open end of each of the first and second lens barrels along the open end. The eye cup includes two or more ventilation paths through which inside and outside of the eye cup communicate with each other in an intersecting direction that intersects a barrel axis direction of the first and second lens barrels and an arrangement direction in which the first and second lens barrels are arranged.

Abstract: A display apparatus includes: a first lens barrel in a bottomed barrel shape and including, at the bottom, a first display that displays an image; a second lens barrel in a bottomed barrel shape and including, at the bottom, a second display that displays another image; a support member elongated in an arrangement direction of the first and second lens barrels, and supporting, by passing through the first and second lens barrels in the arrangement direction, at least one of the first and second lens barrels to allow the at least one lens barrel to move in the arrangement direction; and temple parts respectively connected to two ends of the support member in the arrangement direction. The first lens barrel includes first and second sound pickup devices, the second lens barrel includes third and fourth sound pickup devices, and the temple parts respectively include fifth and sixth sound pickup devices.
