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.

摘要： To provide an audio reproduction apparatus in which a general user inputs simple and easy settings so that audio beams of respective channels can be set. When an array speaker is installed in a room, the user inputs the shape of the room into the audio reproduction apparatus. Based on the shape of the room, the audio reproduction apparatus determines a beam control pattern indicating which directions audio signals of the channels should be formed respectively. The audio reproduction apparatus reads beam control data including delay times for forming the beams in the directions from a pattern memory, and automatically sets the beam control data in a DSP. Thus, only when the user inputs the shape of the room, the beams are controlled with a beam control pattern suitable to the room so that multi-channel audio can be reproduced optimally.

摘要： Signals on respective RL, FL, C, FR, RR channels are divided into high frequency signals and low frequency signals by HPFs and LPFs respectively. The low frequency signals on the RL, FL, and C channels are superposed and output from a left-side woofer 21-1, while the low frequency signals on the RR, FR, and C channels are superposed and output from a right-side woofer 21-2. A predetermined directivity is given to the high frequency signals on respective channels by directivity controlling portions 17-1 to 17-5 respectively, and resultant signals are output from respective speaker units 20-1 to 20-n of an array speaker to generate virtual sound sources by the reflection from wall surfaces. A crossover frequency f2 of the rear channels (RL, RR) is set higher than a crossover frequency f1 of the front channels (FL, FR), and the signals on the rear channels are shaped into a narrow beam to generate a high-quality surround sound field.
