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.

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, medium and apparatus for enhancing an acoustic signal using an auditory property. An acoustic signal is enhanced by generating a plurality of harmonic signals based on a predetermined acoustic signal frequency, selecting harmonic signals, which exist in an area masked by the predetermined harmonic signal, from among the generated plurality of harmonic signals, and outputting harmonic signals remaining after excluding the selected harmonic signals from the generated plurality of harmonic signals. The enhancement results in a bass signal of good sound quality and having a low distortion ratio, without changing the structure of a micro speaker.

摘要： Provided are an apparatus and method for controlling an acoustic radiation pattern output through an array of speakers. The apparatus stores a plurality of filter values for forming a plurality of corresponding control patterns set in advance from an input signal. The apparatus forms a compensation control pattern such that signals output through the array of speakers have an intended pattern in consideration of a filter value of a focusing filter. The apparatus selects at least one of the control patterns set in advance to form the compensation control pattern, and processes the input signal using a filter value corresponding to the selected control pattern.
