Abstract:

A speaker apparatus, a method for processing input signals of the speaker apparatus and an audio system are provided. The speaker apparatus includes: a first plurality of speakers, arranged at an interval in a row, where acoustic energy radiation generated by the first plurality of speakers is greater in a first zone than in a second zone in a first frequency range； a second plurality of speakers, symmetrically disposed at two sides of the first plurality of speakers with openings at the two sides facing outwardly, where acoustic energy radiation generated by the second plurality of speakers is greater in a third zone than in a fourth zone in a second frequency range； and the first frequency range overlaps with the second frequency range. Therefore, the speaker apparatus, the method and the audio system can achieve a wide spacious effect and provide a near-real surround experience to listeners.
