    摘要： A spatial sound energy (SSE) distribution control apparatus calculates filter coefficients for controlling distribution of the sound energy of an input signal, in consideration of a sound energy ratio between a reduction region for reducing transmission of a sound energy emitted through an array speaker and a concentration region for concentrating transmission of the sound energy and also in consideration of a sound energy efficiency of the concentration region. Also, the SSE distribution control apparatus determines an array size of a speaker in a case where the sound energy ratio is maximized, according to frequency variation of the input signal.

    摘要： An apparatus and method for forming a Personal Sound Zone (PSZ) at a location of a listener are provided. An apparatus for simultaneously controlling a near sound field and a far sound field may classify the near sound field and the far sound field based on a distance between an array speaker and a listener, and may control the near sound field and the far sound field and thus, it is possible to perform focusing even when the listener is located in adjacent to the array speaker. Additionally, the apparatus may generate a directive sound source using the array speaker, and at the same time, may reduce a sound pressure in a far field, thereby reducing a sound source spreading to the far field while focusing is performed at the location of the listener.

    摘要： An operation method of a binaural system and the binaural system adopting the method is provided. That is, a method to stably provide a stereo sound, creating a plurality of sound images and expanding a listening sweet spot by using a plurality of static filters or modulation filters when a user listens to an audio sound, even if a user turns his/her head to or moves, and the method adopted by the binaural system. The binaural system includes a plurality of static filters connected in parallel to each other, the plurality of static filters creates a sound image in a different location by controlling an output location of an inputted audio signal, and a control unit inputting the audio signal to the plurality of static filters.

    摘要： The spindle motor includes a rotating shaft and a sleeve. The rotating shaft has a stepped portion in a fluid dynamic pressure shafting system. The sleeve is fitted over the circumferential outer surface of the rotating shaft. A sleeve recess is formed in the inner surface of the sleeve so that the edges of the stepped portion are spaced apart from the sleeve.
