Abstract:
The present disclosure relates to an audio device (900) for providing an improved three-dimensional sound experience by means of the generated soundfield. To achieve this, the audio device (900) comprises a housing (901), which has an elliptical torus shape and a plurality of loudspeakers (903a-903h), and a processing circuitry (1310). 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 (903a-903h) 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 (1204a, 1204b) of the soundfield. Hereby, the desired frequency ranges (HF, MF) may be adjusted using an appropriated distance of the plurality of loudspeakers (903a-903h).
