Definitions
- FIGS. 1 to 3 shows an AMT sound transducer 15 with the membrane arrangement 1 shown in FIGS. 1 to 3.
- the membrane arrangement 1 is arranged between two pole plates 7 and 8 in an air gap 9.
- the membrane assembly 1 is clamped in a frame, wherein only the two frame parts 10a and 10b can be seen from the frame.
- the frame with the frame parts 10a and 10b is connected to two side parts IIa and I Ib.
- the side parts IIa and IIb in turn carry the pole plates 7 and 8.
- FIG. 11 shows the sound transducer of FIG. 10 in a schematically greatly simplified side view, FIG.
- the membrane segments a, b, c are formed and / or arranged so that the acoustic center is common for different frequencies or for the different frequency ranges.
- the geometry of the membrane segments a, b and c, in particular the respective air pockets 59 and 60, is selected so that on the one hand the desired cutoff frequency is transferable and on the other hand, the frequency range of the membrane segments a and c is trimmed so that no further filtering measures are required ,

Abstract
L'invention concerne un dispositif à membrane (16, 26, 39, 47, 62) pour un transformateur de mouvement d'air (AMT), le dispositif à membrane (16, 26, 39, 47, 62) comprenant au moins une membrane (16a) configurée essentiellement en forme de méandres, ainsi que des poches d'air (23, 59, 60) permettant de générer un son en raison de la configuration en méandres d'au moins une membrane (16a). En vue d'améliorer le comportement au rayonnement du dispositif à membrane et de réduire la concentration des sons, l'invention est caractérisée en ce que le dispositif à membrane (16, 26, 39, 47, 62) comprend plusieurs segments de membrane (A, B, C; a, b, c), et en ce que les segments de membrane sont disposés et/ou configurés de telle façon que le dispositif à membrane (16, 26, 39, 47, 62) présente un centre acoustique sensiblement commun.
