Title:
ACOUSTIC DEVICE AND ACOUSTIC CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/143232
Kind Code:
A1
Abstract:
The present invention suppresses attenuation of an output level while reducing interference attributed to a plurality of vibrators. An acoustic control device 30 performs correction processing using an audio processing unit 42 to correct phase delay characteristics including a transmission system from exciters 21L, 21R, which are first and second vibrators coupled by a rigid body, with respect to acoustic signals SR, SL. Subsequently, the acoustic control device 30 controls the exciters 21L, 21R on the basis of the corrected acoustic signals SL1, SR1.
