    Abstract: An audio output device which outputs an audio signal that offsets a direct sound in the first speaker to offset the direct sound generated in the second speaker is provided. The audio output device according to various exemplary embodiments includes a first speaker configured to output a first audio signal, the first speaker being disposed at a first side of the audio output device, a second speaker configured to output a second audio signal, the second speaker being disposed at a second side of the audio output device, and an audio signal processor configured to control the first speaker to output the third audio signal to remove the element provided in the same direction with the first side among the second audio signal.

    Abstract: Provided are a method and apparatus for localizing a multichannel sound signal. The method includes: obtaining a multichannel sound signal to which sense of elevation is applied by applying a first filter to an input sound signal; determining at least one frequency range of a dynamic cue according to change of a head-related transfer function (HRTF) indicating information regarding paths from a spatial location of an actual speaker to ears of an audience; and applying a second filter to at least one sound signal, corresponding to the determined at least one frequency range, of at least one channel in the multichannel sound signal to change the at least one sound signal so as to remove or to reduce the dynamic cue when the multichannel sound signal is output.

    Abstract: An acoustic output device and a control method thereof are provided. The acoustic output device includes: at least one first speaker configured to output a first sound range; a plurality of second speakers configured to output a second sound range that is different from the first sound range; a first crossover circuit connected to the first speaker and one of the plurality of second speakers; a second crossover circuit connected to the first speaker and another of the plurality of second speakers; and a processor configured to control the first and second crossover circuits to provide acoustic signals to the first speaker and the plurality of second speakers, wherein a frequency band of an acoustic signal provided to the first speaker connected to the first crossover circuit is at least partially different from a frequency band of an acoustic signal provided to the first speaker connected to the second of crossover circuit, and wherein a frequency band of an acoustic signal provided to the one of the plurality of second speakers connected to the second crossover circuit is at least partially different from a frequency band of an acoustic signal provided to the other of the plurality of second speakers connected to the second of crossover circuit.
