摘要： An array speaker system canceling non-uniform radiation patterns and a method for implementing the same are provided. The method for canceling non-uniform radiation patterns includes predicting radiation patterns in an array speaker with respect to input signals, generating cancellation signals with respect to at least one region corresponding to non-uniform radiation patterns of the predicted radiation patterns, synthesizing the input signals and the cancellation signals, and outputting the synthesized signals to the array speaker. Sound signals from which non-uniform radiation patterns having distorted sound are cancelled such that a stable sound field having uniform radiation characteristics may be obtained and provided to a listener.

摘要： A method and apparatus for compensating for a near-field effect in a speaker array system is provided. The method includes generating a virtual sound signal at a position, which is separated from a speaker array by a predetermined distance, based on an input sound signal, and outputting the generated virtual sound signal using the speaker array. Therefore, the near-field effect, in which a sound radiated from a speaker array is distorted to have non-uniform radiation characteristics near the speaker array, can be compensated for. Consequently, the method and apparatus can provide a stable sound field, into which non-uniform radiation characteristics uniformly converge, to a listener.

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.

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.
