Driver Directivity Control by Sound Redistribution

Document Thumbnail

The directivity of a single loudspeaker driver is controlled by adding an acoustic reflector* to an ordinary driver. The driver radiates upwards and the sound is redistributed by being reflected off the acoustic reflector. The shape of the acoustic reflector is non-trivial and yields an interesting and useful directivity both in the vertical and horizontal plane. 2D FEM simulations and 3D BEM simulations are compared to free field measurements performed on a loudspeaker using the acoustic reflector. The resulting directivity is related to results of previously reported psychoacoustic experiments.
