AI Technical Summary
Technical Problem
The separate placement of speakers and motors in existing electronic devices results in a large space occupation and affects the user experience.
Method used
This vibration-generating device integrates a speaker and a motor. Through the design of a magnetic circuit system, a first vibration system, and a second vibration system, the speaker and motor structures are integrated. The design of dual voice coils and multiple magnetic parts increases the magnet volume and reduces the device thickness.
Benefits of technology
It improves the integration and performance of vibration-generating devices, saves space, reduces distortion, and enhances sound quality and vibration experience.
