AI Technical Summary
In existing screen vibration devices, the drive coil module requires a large space and has limited frequency response. The vibration of the piezoelectric sheet is weak, and the fixed connection between the screen and the back cover causes uneven vibration, which affects the touch screen experience.
A screen vibration module based on piezoelectric ceramics is adopted. The screen and the back shell are slidably connected by the first bracket and the second bracket. The vibration component composed of piezoelectric cymbals and vibrating plates uses resonance to amplify the vibration effect. The natural frequency is matched by editing the waveform. Combined with the material and structural design of the low-frequency vibrating plate, the vibration is enhanced.
It achieves uniform screen vibration and amplifies the vibration effect, with low vibration noise, improved user experience, and resonance amplification of vibration effect, resulting in a good vibration sensation that is not sharp.
