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.

摘要： Provided are apparatus and method for focusing sound so that a sound radiation pattern output from an array speaker system composed of a plurality of speakers may approach a target sound radiation pattern. The sound focusing apparatus uses a focusing filter formed in consideration of sound characteristics of the array speaker system. In addition, the sound focusing apparatus may compensate for delay and gain values of each channel generated when an input signal is replicated to a plurality of channels and output through an array speaker in the array speaker system.

摘要： A method and apparatus for reproducing a front surround sound, whereby a coefficient of at least one beamforming filter set is determined based on a sound pressure ratio of an emphasis area to a suppression area for each of the at least one channel signal included in a sound signal, where the emphasis area is an area into which the at least one channel signal is focused and the suppression area is an area within which the at least one channel signal is blocked, the at least one channel signal passes through a corresponding beamforming filter set, and the at least one filtered channel signal is output through an array speaker.

摘要： Provided are an array speaker system and a method of implementing the same. The array speaker system includes a group setting unit setting one or more combinations of a plurality of speakers included in an array speaker system into at least one group according to a predetermined adjustment factor, a signal assignment unit dividing an input signal into at least one sound source signal according to the adjustment factor and selectively assigning the divided sound source signal(s) to the set group(s), a sound adjustment unit adjusting a sound source signal to be output through speakers within the group according to sound source characteristics of the group, and a signal output unit outputting the adjusted sound source signal through the speakers within the group. Using the array speaker system, sound adjustment and sound output optimized for each frequency band can be obtained during output of a sound source signal having a broad range of frequencies, and a near-field effect that distorts an output sound source signal can be prevented. Moreover, stereo and multi-channel effects can be obtained and the directivity of the array speaker system can be improved.
