Abstract
An audio device for providing an improved three-dimensional sound experience by means of the generated soundfield is provided. The audio device comprises a housing, which has an elliptical torus shape and a plurality of loudspeakers, and a processing circuitry. The processing circuitry is configured to process a plurality of input signals (L, R, UL, UR) in a manner, which enables the plurality of loudspeakers to form at least a first (DH1, DH3) and second (DH2) horizontal dipoles for crosstalk cancellation within at least two different frequency ranges (HF, MF), and to form at least a first vertical dipole (DV1, DV3) for sound elevation of the soundfield. Hereby, a desired frequency ranges (HF, MF) may be adjusted using an appropriated distance of the plurality of loudspeakers.
