Abstract
An interaction apparatus comprises: a loudspeaker array, comprising speaker units, where each speaker unit is configured to make sound according to an input signal; an obstacle detection module, configured to detect an obstacle parameter corresponding to an obstacle inside space on a side of a sound-making surface of the loudspeaker array; and a compensation module, configured to adjust, according to the obstacle parameter, the input signal corresponding to a speaker unit of the speaker units, and compensate for a sound-making effect of the loudspeaker array influenced by the obstacle. A loudspeaker array comprising the speaker units can be disposed, an obstacle that influences a sound-making effect of the loudspeaker array can be detected, and an input signal of a corresponding speaker unit can be adjusted when the obstacle exists, thereby alleviating influence from the obstacle on the sound-making effect during use, and improving user experience.
