  • a maximum inner diameter of the sound guide unit is determined by the boundary conditions described above.
  • the size of the volume 12 in front of the membrane 11 is dependent on the diameter of the membrane 11. With a small diameter of the membrane 1 1, it is easier to keep this volume small and thus move the increase to higher frequencies. For larger diameters of the membrane 1 1, the resulting larger volume 12 in front of the membrane must be compensated by a smaller acoustic mass of the sound guide unit.
  • Fig. 6 shows a graph of two frequency responses.
  • the frequency response shown in dashed lines corresponds to an in-ear earphone with a smaller volume 12 in front of the diaphragm.
  • the continuous frequency response corresponds to a frequency response of an in-ear listener with a larger volume 12 in front of the membrane 1 first
  • According to the invention can be achieved by reducing the acoustic mass of the sound guide unit to the same extent as an increase in the volume of approximately the same frequency response. According to the invention this is achieved by a sound guide unit with an elliptical inner cross section.

Abstract

L'invention prévoit un écouteur intra-auriculaire avec une membrane (11), un premier volume (12) devant la membrane et une unité de guidage du son (13) pour guider dans un canal auriculaire d'un utilisateur le son produit par la membrane (11). L'unité de guidage du son (13) comprend une section interne de forme sensiblement elliptique.
