AI Technical Summary
Existing ultra-thin speakers struggle to achieve both high power and long stroke while maintaining an ultra-thin design, resulting in poor bass performance.
The cone and spring are connected as one unit by a basket to form a suspension system. The spring is surrounded on the outside of the basket to avoid contact with the magnet assembly. Combined with annular grooves and elastic fasteners, the connection stability is enhanced, thus achieving suspension support for the cone.
While maintaining a small speaker thickness, we achieve high power and long stroke, improving bass performance and producing lower frequencies and greater volume.
