Abstract

An electroacoustic transducer (1) has a diaphragm (19), the diaphragm (19) has a diaphragm axis (5) and an annular pleated area (22), and the pleated area (22) is provided with a plurality of pleats ( 26, 27, 28, 32, 33, 34, 38, 39, 40), and the diametrically opposite pleats include at least one different pleat parameter, characterized in that the annular pleat zone (22) is divided into a plurality of rings Segments (23, 24, 25), wherein the pleats (26, 27, 28) in the center of the ring segment (23, 24, 25) stretch straight along the radial direction (29, 30, 31), and in the ring segment (23 , 24, 25) all other pleats (32, 33, 34) are parallel to the pleats (26, 27 , 28) Stretch.

Description

technical field

[0001] The invention relates to an electroacoustic transducer with a diaphragm having a diaphragm axis and an annular pleated region in which a plurality of pleats is provided.

[0002] The invention also relates to a membrane for an electroacoustic transducer, which membrane has a plurality of pleat-shaped annular pleat regions in which the membrane axis is arranged. Background technique

[0003] An electro-acoustic transducer corresponding to the embodiment described in the first paragraph and a membrane corresponding to the embodiment described in the second paragraph are known, for example, from US patent 6,308,327A. In the solution known from the above-referenced patent, the plurality of pleats provided in the pleat zone have the same structure throughout the pleat zone, ie the same mechanical structural state always occurs successively. In other words, this means that all pleats agree with each other in terms of pleat parameters, thus having the same p...
