<p>In a diaphragm arrangement for electroacoustical transducers, in particular for headsets, one or more diaphragms lie in one plane which extends in the immediate proximity of the user's external ear and preferably parallel to the tangential plane of the user's external ear. In order to enable the use of the headset to better discern direction and distance by hearing, the diaphragm is divided into several coherent, preferably stripshaped sections or composed of several, preferably stripshaped part diaphragms which are adjacent or follow each other in that particular direction in which the user's ear is to locate the direction of sound incidence in the use position. Each diaphragm section or each part diaphragm is provided with a separate drive element or system, there being provided, at least between drive elements or systems of two diaphragm sections or part diaphragms following each other in the sense of the required direction of sound incidence, an element delaying the transmit time of the signals and/or a delay circuit.</p> |
