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 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： 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.
