Symmetric dual suspension speaker structure

A symmetric dual suspension speaker structure, comprising:

• a basin frame, configured with an opening;
• a U-shaped iron, wherein the U-shaped iron is an element having a basin-wise appearance;
• a magnetic permeability ferrite ring, installed between the basin frame and the U-shaped iron, with the top end thereof being in contact with the bottom end of the basin frame and the center thereof having a ring opening, wherein a cross section of the ring is U-shaped;
• a corrugated rim, including a corrugated rim outer ring and a corrugated rim inner ring, in which the corrugated rim outer ring is installed at the opening of the basin frame;
• a diaphragm, in which the upper surface of the diaphragm is connected to the corrugated rim inner ring, and the peripheral edge around the upper surface of the diaphragm can be stretched in the vertical direction to form a barrel component;
• a sound coil, winding around the outer surface of the barrel component;
• a damper, including a damper outer ring and a damper inner ring, in which the damper inner ring is used to be connected with the outer bottom edge around the barrel component of the diaphragm through the opening of the basin frame and the ring opening in the magnetic permeability ferrite ring, while the damper outer ring is fixedly clamped between the top end of the U-shaped iron and the bottom end of the magnetic permeability ferrite ring;
• and
• a magnet, set up inside the U-shaped iron, and the top end thereof further installed with a washer thereby clamping in package the magnet in cooperation with the U-shaped iron;
• wherein an edge of the basin frame, an edge of the U-shaped iron, and an edge of the magnetic permeability ferrite ring are configured with mutual snapping structures such that the basin frame, the U-shaped iron and the magnetic permeability ferrite ring are assembled in stack along a vertical direction, while outer peripheries of the U-shaped iron and the magnetic permeability ferrite ring are in direct contact, and the damper is fixedly clamped between inner peripheries of the U-shaped iron and the magnetic permeability ferrite ring.
