Speaker system for an in-the-ear hearing device
A loudspeaker system for a hearing device to be worn in the ear has a loudspeaker with a housing, which has a sound exit opening that is arranged in a coupling surface of the housing. The loudspeaker system additionally has an antenna body, which has a carrier plate formed with a sound passage opening, a carrier sleeve rigidly connected to the carrier plate and fluidically connected to its sound passage opening, and an antenna coil wound around the carrier sleeve. Furthermore, the loudspeaker system has a damping body made of a yielding material, by way of which the loudspeaker is coupled using its coupling surface with the carrier plate of the antenna body.
1 . A loudspeaker system for a hearing device to be worn in an ear, comprising:
a loudspeaker having a housing with a coupling surface and a sound exit opening formed in said coupling surface of said housing;
an antenna body having a carrier plate formed with a sound passage opening, a carrier sleeve rigidly connected to said carrier plate and fluidically connected to said sound passage opening, and an antenna coil wound around said carrier sleeve; and
a damping body made of a yielding material, said damping body connecting said loudspeaker by way of said coupling surface of said housing with said carrier plate of said antenna body; and
wherein at least one of a material thickness or a shear modulus of said damping body is selected such that, with reference to a specified falling height, which relates to a height of a person wearing the hearing device, and a specified maximum acceleration for the loudspeaker, said damping body provides for a sufficient braking path.
2 . The loudspeaker system according to claim 1 , wherein said damping body is substantially plate-shaped.
3 . The loudspeaker system according to claim 2 , wherein said damping body is configured to enable said loudspeaker to plunge slightly into said damping body.
4 . The loudspeaker system according to claim 1 , wherein said damping body has a wedge shape.
5 . The loudspeaker system according to claim 2 , wherein said damping body is formed with protruding elements for positioning said loudspeaker.
6 . The loudspeaker system according to claim 5 , wherein said protruding elements are formed by a side wall of said damping body.
7 . The loudspeaker system according to claim 1 , wherein said damping body has additional fastening means for mounting said loudspeaker in a housing body of the hearing device.
8 . The loudspeaker system according to claim 1 , wherein the braking path is defined parallel to said coupling surface.
9 . The loudspeaker system according to claim 1 , wherein the at least one of the material thickness or the shear modulus is moreover dimensioned as a function of a deceleration force and an attachment surface of said damping body on one or both of said coupling surface and said carrier plate, based on the formula

10 . The loudspeaker system according to claim 1 , which comprises connection contacts of said loudspeaker arranged in a connection surface of said housing that differs from said coupling surface.
11 . A hearing device to be worn in an ear, the hearing device comprising:
a housing body;
a loudspeaker system according to claim 1 mounted in said housing body by way of the antenna body.
