Abstract

A speaker apparatus includes: a first outputting unit that has a first speaker unit group in which a plurality of speaker units are arranged, and that outputs a supplied audio signal from the first speaker unit group as a sound which is directed in a direction; a second outputting unit that has a second speaker unit which is placed so that a front direction of the second speaker unit in which a frontage of the second speaker unit faces is different from a front direction of the first speaker unit group in which a frontage of the first speaker unit group faces, and that outputs a supplied audio signal from the second speaker unit as a sound; and a supplying unit that separates an input audio signal into an audio signal in a low-frequency band where a frequency band which is higher than a first frequency is attenuated, and an audio signal in a high-frequency band where a frequency band which is lower than a second frequency is attenuated. The supplying unit supplies the audio signal in the low-frequency band to the first outputting unit, and supplies the audio signal in the high-frequency band to the second outputting unit.

Description

technical field

[0001] The present invention relates to a technology for providing surround sound effects by using a speaker array. Background technique

[0002] A method has been proposed in which directivity is given to an audio signal by a speaker array and the signal is reflected through walls to reach a listener, thereby achieving a surround sound effect. For example, JP-A-6-205496 discloses a related technique in which audio signals from right and left channels of a speaker array arranged in front of a listener reflect off a wall to reach a listener. According to this technique, it is possible to give a surround sound effect when a sound image is located in a direction facing the right wall and the left wall with respect to the listener.

[0003] When it is necessary to use a speaker array to obtain an excellent surround sound experience, the directivity of the sound must be enhanced. In order to enhance the directivity of sound, it is necessary to use many speaker u...
