Abstract: An apparatus and method for representing a three-dimensional (3D) sound field, based on a velocity vector of an acoustic particle is disclosed. A transfer function S610, based on a velocity vector of an acoustic particle and a sound source strength of the acoustic particle, is generated. A cost function S620 is generated based on a target velocity vector and a represented velocity vector. A set of loudspeaker input signals S630 are then generated that minimizes the cost function based on the transfer function, which aims to prevent the generation of an excessive output. Generation of the transfer function may comprise generating a transfer function matrix based on the radial component of the velocity vector, evaluated at control points arranged on a control circle or sphere with variable radius with respect to an excitation frequency.

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.
