AI Technical Summary
Technical Problem
In bone conduction speakers, as the functions become more complex, the number of wires inside the core housing increases, taking up a lot of space and easily causing vibrations and noises, which affects the sound quality.
Method used
Flexible circuit boards are used to set pads inside the mechanism housing, and wires are connected by flexible leads to optimize the wiring layout, reduce wire slack, and avoid vibration and abnormal noise.
Benefits of technology
The wiring layout inside the housing of the headphone core has been optimized, saving space and improving the sound quality of the headphone core.
