ARRAY SPEAKER APPARATUS

Title:

ARRAY SPEAKER APPARATUS

Document Type and Number:

WIPO Patent Application WO/2006/090799

Kind Code:

A1

Abstract:

Each of the signals of RL, FL, C, FR and RR channels is divided by HPF and LPF into high and low frequency signals. The low frequency signals of the RL, FL and C channels are superimposed and outputted from a left side woofer (21-1), while the low frequency signals of the RR, FR and C channels are superimposed and outputted from a right side woofer (21-2). The high frequency signals of the respective channels are imparted respective predetermined directivities by directivity control parts (17-1 to 17-5) and outputted from speaker units (20-1 to 20-n) of the array speaker, thereby generating virtual sound sources using reflections by the walls. The crossover frequency (f2) of the rear channels (RL,RR) is caused to be higher than the crossover frequency (f1) of the front channels (FL,FR), thereby forming narrow beams of the rear channels so as to generate a sound field of a high quality.
