Earphone Core Module Layout for Battery Vibration Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing earphones suffer from instability in the connection between the battery assembly and the housing, leading to vibrations that degrade sound quality during operation.
Innovation Solution
A core module design with a housing featuring separate accommodation spaces for the battery and driving assemblies, where the first limiting portion limits the battery assembly's position and movement relative to the housing, ensuring stability by preventing rotation and movement perpendicular to the assembly direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery assembly is simply placed in the housing without limiting portions, then the assembly process is simple, but the battery assembly becomes unstable and causes vibrations that degrade sound quality
Solution Approach 1:
The housing's accommodation space is segmented into multiple regions using limiting portions (first limiting portion, second limiting portion, third limiting portion) that divide the space to precisely constrain the battery assembly's position, preventing movement in multiple directions and improving connection stability
Solution Approach 2:
Limiting portions are strategically placed at specific locations within the accommodation space to provide localized constraints. The first limiting portion prevents movement in one direction, the second limiting portion constrains rotation, and the third limiting portion prevents movement in another direction, creating targeted stability without unnecessary complexity
2Object-generated harmful factors
If the battery assembly is allowed to move freely in the housing, then the manufacturing process is simple, but vibrations occur during operation that degrade sound quality
Solution Approach 1:
The limiting portions are pre-designed and integrated into the housing structure before battery assembly installation. These features preliminarily establish the precise positioning and constraint geometry, ensuring that when the battery assembly is installed, it is automatically constrained to the correct position and orientation, preventing vibrations during operation
Solution Approach 2:
The patent replaces complex mechanical fastening systems with a streamlined limiting portion design that uses the housing structure itself to constrain the battery assembly. The limiting portions create mechanical constraints through geometric interference rather than requiring additional fasteners or complex mounting mechanisms

AI summary
The present disclosure provides a core module and an earphone. The core module comprises a housing, a battery assembly, and a driving assembly. The housing is provided with a first accommodation space and a second accommodation space. The battery assembly is accommodated in the first accommodation space along a first preset assembly direction. The driving assembly is accommodated in the second accommodation space along a second preset assembly direction. The first preset assembly direction and the second preset assembly direction are provided at an acute angle. A first limiting portion is disposed in the first accommodation space. A projection of the first limiting portion on a cross section perpendicular to the first preset assembly direction does not overlap with a projection of the battery assembly on the cross section perpendicular to the first preset assembly direction. The first limiting portion is configured to limit a position of the battery assembly.
