Abstract
A loudspeaker apparatus includes a speaker array that has a plurality of speaker units which are arranged on a sound emitting surface of the speaker array, and emits sound beams on a plurality of channels, an angle sensing section that senses an angle change displaced from a previously set reference angle of the sound emitting surface, and an adjusting section that adjusts output angles of the sound beams in response to the angle change.
Claims8
A loudspeaker apparatus comprising:
- a speaker array that has a sound emitting surface and a plurality of speaker units arranged relative to the sound emitting surface that emits sound beams for a plurality of channels;
- an angle sensing section that senses an angle change in the sound emitting surface relative to a set reference angle position of the sound emitting surface;
- and
- an adjusting section that adjusts output angles of the sound beams in response to the angle change sensed by the angle sensing section, and
- wherein the adjusting section adjusts the output angles of the sound beams except a sound beam for a center channel among the sound beams for the plurality of channels.
