Abstract
A speaker system has a speaker array including a plurality of first speakers and a first filter array. A peak of the directivity of reproduced sounds output from the speaker array. And the peak being in a direction in which the plurality of first speakers are arranged, is shifted toward a wall surface due to first filter processing performed by the first filter array.
Claims12
A speaker system comprising:
- a speaker array including a plurality of first speakers that are linearly placed and each of which receives a first signal that has been processed by first filter processing and amplification processing;
- a first filter array configured to perform the first filter processing;
- and
- a multi-channel amplifier configured to perform the amplification processing;
- wherein
- the speaker array is placed in reproduction space that has a wall surface crossing an array direction in which the plurality of first speakers are arranged, and
- a peak of a directivity of reproduced sounds, corresponding to the first signal, that have been output from the speaker array, the peak being in the array direction, is shifted toward the wall surface due to the first filter processing.
