Patent ID: 8189828

Claim:
An audio device comprising: a speaker array device containing a plurality of speaker units aligned in an array; a first sound level controller for controlling a sound level of at least one input audio signal; a high-pass filter for passing only high-frequency components of the audio signal output from the first sound level controller; a main processing section for controlling supplying timings at which the audio signal output from the first sound level controller is supplied to the speaker units of the speaker array device, so that the speaker array device outputs at least one sound beam emitted in a prescribed direction; a high-band processing section for controlling the high-frequency components of the audio signal output from the high-pass filter to the speaker units of the speaker array device so that the high-frequency components output from the high-pass filter emit with directivity characteristics distributed in a wide angle; and a second sound level controller for separately controlling an output level of the high-frequency components of the audio signal output from the high-pass filter in response to at least one of the sound level of the audio signal output from the first sound level controller or an emission direction of the sound beam.
