Flat loudspeaker radiation characteristics controlling method, involves compensating sound signals that are emitted from loudspeaker by phase shifted compensation signal in moment of passage via another loudspeaker

摘要

#CMT# #/CMT# The method involves compensating sound signals emitted from a flat loudspeaker (1) by a compensation signal in moment of passage via another flat loudspeaker (2). The compensation signal is phase shifted around 180 degree and corresponded to intensity and a signal forum of the sound signals, where the compensation signal is mathematically calculated. The compensation signal leaves the flat loudspeaker (2) after the passage via the loudspeaker (2). The compensation process is repeated in the flat loudspeaker (2) by using the signal that is phase shifted around 180 degree as the sound signal. #CMT#USE : #/CMT# Method for controlling radiation characteristics of parallelly arranged flat loudspeakers that radiate on both sides. #CMT#ADVANTAGE : #/CMT# The method allows the sound signals emitted from the loudspeaker to be output in a direction without the influence of sound radiation in another direction. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic representation of a loudspeaker with a signal processing circuit.'(Drawing includes non-English language text)' 1, 2 : Flat loudspeakers.
