ELECTRO-ACOUSTIC TRANSDUCER OF RIBBON TYPE, LOUDSPEAKER SYSTEM COMPRISING SUCH A TRANSDUCER AND LOUDSPEAKER ARRANGEMENT COMPRISING AT LEAST TWO SUCH TRANSDUCERS.

摘要

The present invention relates to an electro-acoustic transducer of ribbon type comprising an elongated membrane unit (5) having a longitudinal main portion (22) that extends in a single plane.The membrane unit (5) further comprises at least one section (21a, 21b) that extends in another plane with a normal that deviates an angle (υ), preferably less than 15°, from the normal of the longitudinal main portion (22). The invention also relates to a loudspeaker system that comprises at least one such electro-acoustic transducer and to a loudspeaker arrangement that comprises at least two such electro-acoustic transducers arranged on top of each other to provide an essentially continuos curved line-source.
