Abstract: PURPOSE: A force acoustic dipole and force acoustic multi pole array using the same improves all kinds of the acoustic regenerations performance by providing the sound effect having without disturbance presence. CONSTITUTION: A phase shifter(130) outputs the first acoustic signal by phase-converting the input signal to the designated angle. The phase inverter outputs the second acoustic signal by turning reversely the phase of the first acoustic signal. The first, and 2 sound pressure controllers(150a, 150b) respectively control the first, and the sound pressure of 2 acoustic signal. The first and second AMPs(160a, 160b) respectively amplify the first controlled the sound pressure, and 2 acoustic signal. The first and second polar speakers(110, 120) respectively output the amplified first as described above, and 2 acoustic signal. The sub steering part(170) steers the first outputted from the first and second polar speakers, and the acoustic lobe direction according to 2 acoustic signal.
