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： 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： A speaker includes a housing; a support assembly installed on the lower end of the housing to support the housing; at least one first speaker unit installed in the housing to reproduce a sound signal; and a second speaker unit installed in the support assembly to reproduce a sound signal which belongs to a low sound band. Openings are defined through both sides of the support assembly to transmit to the outside sound reproduced by the second speaker unit. A guide cone is provided to the lower end of the support assembly to guide sound toward the openings. The speaker unit can be installed in a baffle which is supported at the opened front end of the housing to be rotated about a vertical axis. Through rotating the baffle, the speaker unit can be actually rotated within a predetermined range to change a sound transmission direction.
