摘要： A method and apparatus for outputting a sound source signal by using a virtual speaker are provided. The method includes generating a virtual sound source signal delayed by a virtual delay value, instead of by the minimum delay value, according to a sampling rate of an input sound source signal, from the input sound source signal; generating a speaker output signal in which a sampling rate is changed based on the input sound source signal and the generated virtual sound source signal; and outputting the generated speaker output signal. Thus, a non-uniform radiation pattern, which causes distortion in a sound radiated from a speaker array, is removed and the limitation of a frequency band of a controllable sound source signal is overcome, thereby providing a stable sound.

摘要： Provided are a method and apparatus for controlling a sound field through an array speaker. The method includes calculating a coefficient of a filter that controls sound pressure of an input signal, based on a sound pressure ratio of a suppression area that suppresses sound emitted from an array speaker and an emphasis area that emphasizes the sound, and sound pressure efficiency in the emphasis area, generating a plurality of output signals that focuses the sound to the emphasis area by filtering the input signal based on the calculated coefficient of the filter, and outputting a sound field controlled sound based on the generated plurality of output signals. Accordingly, a listener in a predetermined direction and distance from the array speaker can clearly hear sound, without wearing an earphone or a headset so as to focus the sound only to the listener.
