摘要： A soundbar comprises a housing, at least two transducers of a first group and at least one transducer of a second group. The at least two transducers of the first group are arranged at the front side of the housing and configured to emit sound in a first direction in accordance with two first audio signals so as to reproduce a two dimensional sound field. The at least one transducer of a second group is arranged at a second side of the housing and configured to emit sound in a second direction in accordance with a second audio signal such that the sound emitted by the at least one transducer of the second group reaches a predefined listener's position in a reflected manner to extend the two dimensional sound field in a height direction. The reflection reflecting the sound emitted by the at least one transducer of the second group has an order of at least two.
