ABSTRACT:
The present invention relates to an electronic device for the generation of acoustic spatial effects, which comprises two branch points being connected to an inlet for the left or right signal channels, respectively, of an external source; two earphone outlets for earphones for the left and right ears, respectively; two outlets for two vibrators; between each branch point and the corresponding earphone being inserted a passive circuit; each branch point being connected to the corresponding vibrator via a passive circuit or via a short circuit line. Said passive circuit may comprise a filter system which may be connected via a digital signal processor to an inlet of a terminal amplifier. Said filter system may constitute a sound control system.
