Abstract (en)
[origin: EP1833277A2] The headphone has an in-phase operated, locally wide-banded primary sound transducer (2) arranged in a casing and for reproduction of audio signals in a range of an entire audio spectrum. An out-of-phase operated secondary high audio sound transducer (3) reproduces a high audio range of an audio frequency spectrum. The secondary sound transducer is arranged in an area of an edge of the primary sound transducer before or outside the primary sound transducer, where the edge points from a center of the casing.
