AI Technical Summary

Technical Problem

The vibration and acoustic properties of existing diaphragms cannot fully meet the performance requirements of electronic products, resulting in decreased frequency response and sound distortion.

Method used

Design a diaphragm by setting the folded ring as a first arc segment and a second arc segment connected together, with different thicknesses and curvatures, and an included angle of 90°≤θ1<180°. Set a gradual thickness and a protruding structure at the arc segment connection to adjust the mass effect and damping effect, break up the resonance, and improve the high-frequency response.

Benefits of technology

It improves the flatness and distortion of the speaker's high-frequency response, enhances sound quality, and reduces distortion during vibration.
