Abstract:
A speaker array apparatus includes a speaker array, a beam forming portion that is configured to cause the speaker array to output the sound beam, a beam control portion that is configured to sweep with the test sound beam in a predetermined angle range in a vertical direction with respect to a horizontal direction, a microphone, a distance obtaining portion that is configured to obtain a distance between the speaker array and the microphone, and a storage portion that is configured to store pickup sound data that is associated with the output angle. The beam control portion sets a minimum output angle of the angle range to be larger as the distance obtained by the distance obtaining portion is smaller.
