Abstract
An area-sound reproduction system is provided that includes a speaker array having a plurality of speakers arranged side by side, a sound collector configured to collect an environment sound in an environment where the area-sound reproduction system is installed, a processor, and a memory having a computer program stored thereon. The computer program causes the processor to execute operations, including adjusting signals that the plurality of speakers are caused to output as reproduced sounds according to a reproduction condition on a control line, and causing the plurality of speakers to output the reproduced sounds.
Claims12
An area-sound reproduction system, comprising:
- a speaker array including a plurality of speakers arranged side by side;
- a sound collector configured to collect an environment sound in an environment where the area-sound reproduction system is installed;
- a processor;
- and
- a memory having a computer program stored thereon, the computer program causing the processor to execute operations, including
- adjusting signals that the plurality of speakers are caused to output as reproduced sounds according to a reproduction condition on a control line,
- wherein the control line includes
- (i) a reproduction line in which sound waves emitted from the speaker array have constructive interference with each other, and
- (ii) a non-reproduction line in which the sound waves have destructive interference with each other, and
- causing the plurality of speakers to output the reproduced sounds,
- wherein the adjusting further includes
- determining a noise level from the collected environment sound, and
- adjusting signals to be output as the reproduced sounds, such that at each frequency, a sound pressure of the reproduced sound reaching the non-reproduction line on the control line does not exceed the noise level.
An area-sound reproduction system, comprising:
- a speaker array including a plurality of speakers arranged side by side;
- a sound collector configured to collect an environment sound in an environment where the area-sound reproduction system is installed;
- a processor;
- and
- a memory having a computer program stored thereon, the computer program causing the processor to execute operations, including
- adjusting signals that the plurality of speakers are caused to output as reproduced sounds according to a reproduction condition on a control line,
- wherein the control line includes
- (i) a reproduction line in which sound waves emitted from the speaker array have constructive interference with each other, and
- (ii) a non-reproduction line in which the sound waves have destructive interference with each other, and
- causing the plurality of speakers to output the reproduced sounds,
- wherein the adjusting further includes
- determining a noise level from the collected environment sound, and
- adjusting signals to be output as the reproduced sounds, such that at each frequency, a sound pressure of the reproduced sound reaching the reproduction line on the control line exceeds the noise level.
An area-sound reproduction method of an area-sound reproduction system, including a speaker array including a plurality of speakers arranged side by side, the area-sound reproduction method comprising:
- collecting an environment sound in an environment where the area-sound reproduction system is installed;
- adjusting signals that the plurality of speakers are caused to output as reproduced sounds accordingly to a reproduction condition on a control line,
- wherein the control line includes
- (i) a reproduction line in which sound waves emitted from the speaker array have constructive interference with each other, and
- (ii) a non-reproduction line in which the sound waves have destructive interference with each other, and
- causing the plurality of speakers to output the reproduced sounds,
- wherein the adjusting further includes
- determining a noise level from the collected environment sound, and
- adjusting signal to be output as the reproduced sounds, such that at each frequency, a sound pressure of the reproduced sound reaching the non-reproduction line on the control line does not exceed the noise level.
An area-sound reproduction method of an area-sound reproduction system, including a speaker array including a plurality of speakers arranged side by side, the area-sound reproduction method comprising:
- collecting an environment sound in an environment where the area-sound reproduction system is installed;
- adjusting signals that the plurality of speakers are caused to output as reproduced sounds accordingly to a reproduction condition on a control line,
- wherein the control line includes
- (i) a reproduction line in which sound waves emitted from the speaker array have constructive interference with each other, and
- (ii) a non-reproduction line in which the sound waves have destructive interference with each other, and
- causing the plurality of speakers to output the reproduced sounds,
- wherein the adjusting further includes
- determining a noise level from the collected environment sound, and
- adjusting signal to be output as the reproduced sounds, such that at each frequency, a sound pressure of the reproduced sound reaching the reproduction line on the control line exceeds the noise level.
