Abstract
An acoustic lens includes: a plurality of fins each having one end portion located on a side opposite to the loudspeaker on a support surface that extends as convexly curved along a predetermined direction when the acoustic lens is viewed from a lateral side, the plurality of fins being arranged in the predetermined direction at substantially equal intervals and substantially in parallel to one another. When the acoustic lens is viewed from the lateral side, the plurality of fins are substantially identical in length, and an elevation angle of the support surface relative to each of the plurality of fins gradually increases from one side to an other side in the predetermined direction.

An acoustic lens that is attached to a loudspeaker, the acoustic lens comprising:
- a plurality of fins each having one end portion located on a curved line that extends as convexly curved along a predetermined direction on a side opposite to the loudspeaker when the acoustic lens is viewed from a lateral side, the plurality of fins being arranged in the predetermined direction at substantially equal intervals and substantially in parallel to one another, wherein
- when the acoustic lens is viewed from the lateral side, the plurality of fins are substantially identical in length, and an elevation angle of the curved line relative to each of the plurality of fins gradually increases from one side to an other side in the predetermined direction.
An acoustic lens that is attached to a loudspeaker, the acoustic lens comprising:
- a plurality of fins each having one end portion located on a curved line that extends as convexly curved along a predetermined direction on a side opposite to the loudspeaker when the acoustic lens is viewed from a lateral side, the plurality of fins being arranged in the predetermined direction;
- and
- a base including a support surface that defines the curved line when the acoustic lens is viewed from the lateral side, wherein:
- when the acoustic lens is viewed from the lateral side, an elevation angle of the curved line relative to each of the plurality of fins gradually increases from one side to an other side in the predetermined direction, and
- the one end portion of each of the plurality of fins is supported by the support surface of the base.
An acoustic lens that is attached to a loudspeaker, the acoustic lens comprising:
- a plurality of fins each having one end portion located on a curved line that extends as convexly curved along a predetermined direction on a side opposite to the loudspeaker when the acoustic lens is viewed from a lateral side, the plurality of fins being arranged in the predetermined direction, wherein:
- when the acoustic lens is viewed from the lateral side, an elevation angle of the curved line relative to each of the plurality of fins gradually increases from one side to an other side in the predetermined direction, and
- the plurality of fins each define a notch at an other end portion opposite to the curved line, the notch having a wedge shape.
