Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-the-ear hearing devices face challenges in achieving a compact design while ensuring vibration-damped mounting of loudspeakers and microphones to prevent structure-borne sound coupling and mechanical damage, which typically require a large installation space.
Innovation Solution
A loudspeaker system with a housing, antenna body, and damping body made of yielding material is used, where the loudspeaker is coupled with the antenna body via a damping body, allowing for vibration decoupling and space-efficient mounting within the limited installation space of in-the-ear devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vibration-damped mounting is used for the loudspeaker, then structure-borne sound coupling and mechanical damage are prevented, but the installation space requirement increases
Solution Approach 1:
The patent combines the antenna body and loudspeaker housing into a single integrated structure. The antenna body serves dual purposes: as a structural support element and as part of the loudspeaker mounting system. This merging eliminates the need for separate vibration-damping mounting structures, achieving reliable mechanical coupling without increasing installation space.
Solution Approach 2:
The antenna body is designed to perform multiple functions simultaneously: it provides structural support for the loudspeaker, serves as a mounting platform, and functions as an antenna element. This multi-functionality allows the system to achieve vibration-damped mounting capabilities without requiring additional dedicated components that would increase the installation space.
2Volume of moving object
If a compact design is pursued for in-the-ear hearing devices, then the device fits better in the auditory canal, but the available space for mounting components with vibration damping is reduced
Solution Approach 1:
The loudspeaker is nested within the antenna body structure. The antenna body houses the loudspeaker components and provides the mounting interface, creating a compact nested arrangement. This nesting allows the vibration-damped mounting functionality to be integrated within the compact antenna structure rather than requiring separate external mounting components.
Solution Approach 2:
The patent merges the antenna function and loudspeaker mounting function into a single integrated component. The antenna body directly serves as the mounting structure for the loudspeaker, eliminating the need for separate vibration-damping elements and achieving both compact size and reliable vibration-damped mounting.
3Reliability
If separate vibration-damping mounting structures are used, then mechanical damage and sound coupling are prevented, but the device complexity increases
Solution Approach 1:
The patent extracts the vibration-damping functionality from separate mounting structures and integrates it directly into the antenna body. Rather than adding complex external mounting mechanisms, the antenna body itself is designed to provide the necessary mechanical coupling and vibration damping, simplifying the overall device structure while maintaining reliability.

AI summary
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.
