2. The support structure enhances the support of the center , is not easy to deform, and can avoid the collapse of the umbrella cap and the deformation of the center , which causes leakage. 3. Release the sound, suppress the treble resonance, and integrate the two-color silicone injection molding process into the newly developed high-frequency waveguide structure to propagate the sound waves. 1. Multiple radioactive, support structure-sleeve is designed by patented technology structure, and the umbrella edge and center are radial. 4. In the process, the propagation obstacles of the sound waves are greatly reduced, the resonance generated by the propagation pipeline is reduced, the burr feeling is reduced, the high-frequency tone is slimmed, and the low-frequency leakage is prevented. 5. The catheter is compatible with a diameter of 3.8mm-6.2mm, and the catheter is universal for most headphones.
