    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: Described herein is an apparatus and method for estimating the amount of power that is to be consumed by an amplifier. An estimation section may be determined based on frame data of an input signal that is to be input to the amplifier. The estimation section may be stored to in a predetermined section, and the amount of power to be consumed by the amplifier may be estimated in advance based on the stored signal. The predetermined section may be determined in consideration of response a characteristic of a power supply of the amplifier. The amount of power may be calculated by assigning weight to the stored signal.

    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: A sound focusing technique is provided to transfer sound to a particular direction. In a sound focusing apparatus, first and second speakers may be arranged to emit sound in opposite directions to form a sound zone. An amplitude and/or a phase of a received signal may be adjusted by a signal processing unit to assign the received signal and the adjusted signal to the first and second speakers, respectively.
