Speaker Diaphragm Avoiding Part for Lead Wire Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional speakers have a large overall size due to the need for space between the voice coil and the diaphragm assembly for the lead wire, which also affects the reliability of the speaker due to interference with the gluing process.
Innovation Solution
The speaker design includes a diaphragm assembly with an avoiding part formed by bending away from the voice coil, creating an avoiding space where the lead wire can pass through, allowing direct bonding of the voice coil to the main body without the need for additional space for the lead wire.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the lead wire is directly sandwiched between the voice coil and the diaphragm assembly, then the speaker structure is simplified, but the overall size becomes excessive and reliability decreases
Solution Approach 1:
The avoiding part extends in the radial direction (perpendicular to the vibration direction) to create an avoiding space, allowing the lead wire to pass through a different spatial dimension rather than occupying space in the vibration direction. This dimensional change resolves the conflict between structural simplicity and compact size.
2Ease of manufacture
If the lead wire is directly sandwiched between the voice coil and the diaphragm assembly, then the assembly process is simplified, but the gluing effect is affected and reliability becomes weak
Solution Approach 1:
The diaphragm assembly is segmented into a main body and a separate avoiding part that extends radially. This segmentation creates a dedicated avoiding space that separates the lead wire from the bonding interface between the voice coil and diaphragm assembly, ensuring proper adhesion while maintaining assembly simplicity.
3Ease of operation
If additional space is allocated for the lead wire between the voice coil and diaphragm assembly, then the lead wire can be properly routed, but the overall size increases excessively
Solution Approach 1:
The avoiding part extends radially outward from the diaphragm assembly main body, creating an avoiding space that accommodates the lead wire in the radial dimension rather than requiring additional space in the axial vibration direction. This allows proper lead wire routing while maintaining compact overall dimensions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design miniaturizes the overall size of the speaker and improves its reliability by eliminating the need for additional space for the lead wire and ensuring a firm bond between the voice coil and the diaphragm assembly.
Implementation Method 1
the voice coil to drive the diaphragm assembly for vibrating and producing sounds
Implementation Method 2
the coil body is bonded with the main body and forms an avoiding space together with the avoiding part. The lead wire passes through the avoiding space

AI summary
A speaker and an electronic device using the speaker are disclosed. The speaker includes a frame with a receiving cavity, and a vibration system and a magnetic circuit system that are contained in the receiving cavity. The vibration system includes a diaphragm assembly and a voice coil. The voice coil includes a coil body and a lead wire extending from the coil body. The diaphragm assembly includes a main body and an avoiding part formed by bending from the main body and in a direction far away from the voice coil. The coil body is bonded with the main body and forms an avoiding space together with the avoiding part. The lead wire passes through the avoiding space to electrically connect with an external power supply. The speaker and the electronic device can have a miniaturized overall size and a better reliability.
