摘要： An apparatus for generating directional sound is provided. By using a time-variant beam pattern, the apparatus may generate constant direct waves in a listening area and may vary reflected waves followed by the direct waves according to time. The apparatus may convolute the time-variant beam pattern with a sound signal, may process an acoustic signal, which may be obtained through convolution, into a multi-channel signal, and may amplify and output the multi-channel signal.

摘要： A sound enhancement apparatus and method which produce low IMD over a broadband frequency region and performs BSE to offer a sound which is natural to the human ears, are provided. The sound enhancement apparatus includes a preprocessor, a BSE signal generator, and a gain controller. The preprocessor divides a source signal into a high-frequency signal and a low-frequency signal and analyzes the low-frequency signal to obtain prediction information regarding a degree of distortion that will be generated by the low-frequency signal. The BSE signal generator generates a higher harmonic signal for the low-frequency signal as a BSE signal to be substituted for the low-frequency signal, wherein the order of the higher harmonic signal is adjusted based on the prediction information regarding the degree of distortion. The gain controller adjusts a synthesis ratio of the low-frequency signal and the BSE signal adaptively depending on the prediction information regarding the degree of distortion.

摘要： Disclosed are an apparatus and method for creating an acoustic radiation pattern, which may improve sound focusing performance to a target position. The acoustic radiation pattern creating apparatus may process an input signal which may be output through a speaker array in a room such that at least one vertical-directional reflected wave component of the input signal may overlap a direct sound of the input signal at the target position. Then, the acoustic radiation pattern creating apparatus may replicate the processed input signal by the number of output channels of the speaker array, and may process the replicated input signals such that the replicated input signals may form a predetermined radiation pattern in a horizontal direction in the room when the replicated input signals are output through the speaker array.

摘要： A disk recording device to manufacture hard disk drives. This disk recording device includes a spindle to detachably hold a disk of a hard disk drive. A spindle motor rotates the spindle. A recording unit records data on a surface of the disk while moving over the surface of the disk held on the spindle. A disk protecting unit covers the surfaces of the disk to protect the disk from an external environment when the disk is rotated. In the disc recording device, the disk protecting unit approaches or moves away from the disk through a reciprocating motion within a predetermined range.
