Abstract: An acoustic lens includes: a plurality of first partition plates aligned apart from each other in the traveling direction of sound waves to be emitted from a loudspeaker. Each of the plurality of first partition plates includes holes through which the sound waves pass. The lengths of the plurality of first partition plates in a first direction are mutually different.

Abstract: An acoustic lens includes an opening and a plurality of partition plates. A sound wave to be emitted from a loudspeaker is input to the opening. The plurality of partition plates form a plurality of sound paths through which the sound wave input to the opening passes. The plurality of partition plates include a first control mechanism and a second control mechanism. The first control mechanism controls directivity, in a first direction, of the sound wave that has passed through the plurality of sound paths and is output to outside. The second control mechanism controls directivity, in a second direction intersecting the first direction, of the sound wave that has passed through the plurality of sound paths and is output to outside.

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.
