Abstract

Die Erfindung betrifft einen Stereo-Kopfhörer mit Raumklangwirkung, aufweisend zwei pro linker und rechter Hörkapsel in bezug auf die normale zentrale Schallwandlerposition vor dem Gehörgang eines Nutzerohrs dezentral angeordnete Schallwandler (3, 17; 7, 8), und
eine Tonsignal-Zufuhreinrichtung (9 bis 11, 16) zum Beaufschlagen der dezentral angeordneten Schallwandler der jeweiligen Hörkapsel mit dem linken bzw. rechten Stereo-Tonsignal und zum Konditionieren dieser Signale relativ zueinander bezüglich Phasenlage und/oder Pegel so, dass
a) einem der beiden dezentral angeordneten Schallwandler (3, 7) das eine originale Stereo-Tonsignal zugeführt wird, während b) dem anderen der beiden dezentral angeordneten Schallwandler (17, 8) das andere Stereo-Tonsignal phasengedreht und/oder pegelreduziert zugeführt wird.

The invention relates to a stereo headphone with a surround sound effect, comprising two per left and right earpiece with respect to the normal central sound transducer position in front of the ear canal of a user pipe locally arranged sound transducer (3, 17, 7, 8), and
a sound signal supply device (9 to 11, 16) for applying the decentralized sound transducer of the respective earphone with the left or right stereo audio signal and for conditioning these signals relative to each other with respect to phase and / or level so that
a) one of the two decentralized sound transducers (3, 7) that an original stereo sound signal is supplied while b) the other of the two decentralized sound transducer (17, 8) the other stereo sound signal is phase-rotated and / or level-reduced supplied.
