AI Technical Summary

Technical Problem

Existing oscillator structures are large in size, have low driving efficiency, high energy consumption, and limited application, making it difficult to meet the needs of miniaturization and diversification.

Method used

Two sets of magnet components are used to drive the armature to vibrate. The coil is wrapped around the outside of the armature. The frame and armature are made of soft magnetic material to form a magnetic circuit. The elastic element is made of non-magnetic material and the spring is bent to provide the restoring force.

Benefits of technology

It achieves miniaturization of the vibration device, improves driving efficiency and sensitivity, has low energy consumption, and can be used in various ways, suitable for air conduction and bone conduction sound transmission.
