摘要： In an audio device equipped with a speaker array device aligning a plurality of speaker units, a sound beam is emitted towards a specific person in a main beam direction, thus realizing the listening of the audio contents with good sound quality. Other persons listen to the audio contents at off-beam positions; hence, leaked sound due to side lobes of the sound beam is transmitted to them with respect to an intermediate band and a low band, thus realizing the listening of the sound with an adequate volume. A high band is subjected to sharp beam control, wherein with respect to an intermediate volume or higher volume, high-frequency components are convoluted with the sound beam and are emitted with non-directivity.

摘要： A multi-channel audio system is constituted using at least one line array speaker unit, in which plural speakers are arrayed in line, wherein the same audio signal is supplied with a prescribed delay time to each of the speakers, thus forming plural sound beams. The plural sound beams are reflected on a wall surface and a ceiling of a room so as to form plural virtual sound sources surrounding a listening position, and emission directions and intensities of the sound beams are controlled so as to localize a phantom at a prescribed position based on the plural virtual sound sources. By appropriately arranging plural line array speaker units horizontally, vertically, and slantingly in such a way that each line array speaker unit forms sound beams distributed and spread in a sectorial form, it is possible to realize a surround audio system having a high degree of freedom with regard to setup positions for forming virtual sound sources.

摘要： To provide a speaker array apparatus and a method for setting audio beams in a speaker array apparatus, in which the degree of freedom in the place where the speaker array apparatus is installed is high, and a user can set audio beams easily. A speaker array apparatus 1 sweeps a range of from 0 degree to 180 degrees in front of a speaker array 10 with audio beams based on an audio signal limited to a band where the angles of the audio beams can be adjusted. The speaker array apparatus 1 collects direct sounds or reflected sounds of the audio beams through a nondirectional microphone 2. The speaker array apparatus 1 analyzes the collected audio data, detects peaks not lower than a threshold value, and checks symmetry among the peaks. When there is a symmetry, the angles where the peaks were detected are set as angles with which audio beams of respective channels of a surround-sound should be output. Thus, outgoing angles of the audio beams can be set in optimum positions in accordance with the shape of a room or the installation position where the speaker array apparatus is installed.

摘要： In a system capable of outputting an audio signal as beams from an array speaker and performing multi-channel reproduction, a plurality of beam setting patterns (reproduction modes) are stored in the memory of a controller. The beam setting patterns include a single basic pattern and a plurality of deformed patterns that use the beam control data of the basic pattern. When the user specifies a reproduction mode via an interface, the beam setting pattern corresponding to the mode is read and set to the signal processor of each channel.

摘要： A speaker array is provided which can increase the orientation when reproducing front channels of a surround sound, increase the density effect, improve the narrow directivity when reproducing a stereo sound and increase the selectivity in selecting reproduction methods which match setting environments. When reproducing a stereo sound by a speaker array for reproducing a surround sound by converting a sound into a beam of sound, the speaker array is divided into a sound reproducing region for an L system and a sound reproducing region for an R system at a central portion thereof. Then, each of the reproducing regions so divided is further divided in to bands. In addition, since a high frequency reproducing region has a high directivity and a strong orientation when the sound is attempted to be reproduced simultaneously by the plurality of speakers as is described above, a reproducing region is limited to part of the reproducing regions. Additionally, when stereo reproducing a front system of a surround sound source, the center orientation is improved by implementing different processings for the L, R systems and C. By adopting this configuration, it is possible to reproduce a sound with a natural stereo effect with no high frequency sound converted 25 into a beam of sound.
