Internally Welded ANC Bluetooth Speaker Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional Bluetooth headset speakers have a splicing structure that is not firmly fixed, leading to unconcentrated sound and poor sound penetration, causing interference with others.
Innovation Solution
An internally welded ANC Bluetooth headset speaker design incorporating a U CUP, magnet, washer, tuning net, pad, tuning net cloth, bracket, voice coil, and diaphragm, with a support frame and mounting grooves for enhanced fixation and sound adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a splicing structure is used for the Bluetooth headset speaker, then the structure is easy to assemble, but the fixation is not firm and the sound is not concentrated
Solution Approach 1:
The patent integrates multiple components (U CUP, bracket, diaphragm, voice coil, magnet, washer, pad, tuning net, tuning net cloth) into a unified internally welded structure. The bracket is welded to the U CUP, forming a rigid integrated assembly that eliminates the loose fixation problems of splicing structures while maintaining assembly feasibility through the organized integration of components.
2Ease of manufacture
If a splicing structure is used for the Bluetooth headset speaker, then the structure is easy to assemble, but the sound penetration is poor and sound spreads around
Solution Approach 1:
The integrated welded structure creates a sealed acoustic chamber that directs sound forward through the diaphragm while preventing sound from spreading sideways. The bracket and U CUP form a unified acoustic enclosure that contains and directs sound waves, reducing interference with surrounding areas.
Solution Approach 2:
The patent incorporates tuning net and tuning net cloth at specific locations (the tuning net is provided on the top of the washer, and the tuning net is located on one side of the pad) to adjust and optimize sound quality in particular directions. These localized acoustic adjustment elements help concentrate sound forward while blocking lateral sound propagation.
3Stability of the object's composition
If an internal welding structure is used, then the fixation is firm and sound can be concentrated, but the manufacturing complexity increases
Solution Approach 1:
The speaker is divided into distinct modular components (U CUP, bracket, diaphragm assembly, voice coil, magnet assembly) that can be manufactured separately and then assembled through welding. This segmentation allows each component to be optimized and manufactured independently, reducing overall manufacturing complexity while achieving firm fixation through the welded connections between modules.
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
The solution provides a more firmly fixed and adjustable sound system, concentrating sound for better penetration and reducing interference.
Implementation Method 1
the voice coil is provided at a bottom of the diaphragm, and the voice coil is located inside the bracket
Implementation Method 2
Sound is produced through the resonance of magnet and washer
