    摘要: Disclosed herein is a spindle motor. 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.

    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 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: An apparatus for and method of externalizing a sound image output to headphones are provided. The method of externalizing a sound image output to headphones includes: localizing the sound image of an input signal to a predetermined area in front of a listener; and signal-processing a left signal component and a right signal component of the input signal with different delay values and gain values, respectively. According to the method and apparatus, the sound image output to the headphones can be localized to a virtual sound stage in front of the listener, thereby reducing tiredness occurring when listening through headphones, and even when a sound source includes many monophonic component, the sound image can be externalized.
