Abstract
The disclosure provides a loudspeaker apparatus and a method of driving the acoustic transducers by predicting and compensating a physical phenomenon of acoustic pressure changes within an enclosure caused by at least one of the acoustic transducers. The loudspeaker apparatus includes an enclosure having an inner space, a first acoustic transducer, a second acoustic transducer, and a controller. The first and second acoustic transducers are mounted on the enclosure and share the same inner space of the enclosure, such as sound bar and the likes. For the operation of the loudspeaker apparatus, the controller applies an algorithm or mathematical model (e.g., transfer function) to an audio signal received from an external source, so that the sound respectively outputted by the first and second acoustic transducers sharing the same inner space may be compensated as if the first and second acoustic transducers are individually mounted on its own enclosure.
