Abstract
A loud-speaking apparatus can comprise a loudspeaker array comprising multiple loud-speaking units, wherein each loud-speaking unit is configured to produce sound according to an input signal; a fault detection module, configured to detect fault parameters of a loud-speaking unit in the loudspeaker array; and a compensation module, configured to adjust, according to the fault parameters, the input signal corresponding to a related loud-speaking unit in the loudspeaker array, to compensate for a sound effect of the loudspeaker array affected by the loud-speaking unit having a sound production fault. A loudspeaker array comprising multiple loud-speaking units can be arranged, and when a loud-speaking unit having a sound production fault is detected, an input signal corresponding to the loud-speaking unit can be adjusted, so as to reduce an impact of the loud-speaking unit having a sound production fault on the sound effect during use, and improve user experience.
