AI Technical Summary

⚠Technical Problem

Existing bone conduction oscillators have shortcomings in terms of sensitivity, vibration stability, and driving force, especially poor low-frequency sensitivity and low vibration efficiency of the driving magnet mechanism.

⚗Method used

The design employs two sets of magnet assemblies and two coils, combined with a magnetic guide plate assembly and a permanent magnet circuit system. The driving force is increased through the relative vibration of the magnetic guide plate and the permanent magnet circuit, and the sensitivity is improved by reducing the spring constant of the spring plate through a reset assembly. The outer shell assembly uses magnetically conductive materials to enhance magnetic field utilization.

🎯Benefits of technology

It improves the sensitivity and driving force of the bone conduction oscillator, enhances the low-frequency effect, reduces the low-frequency resonance frequency, and improves the overall listening effect.
