AI Technical Summary
The connection between the aluminum alloy dust cap and the cone is inconvenient and prone to falling off, resulting in a high defect rate and making it difficult to achieve a secure fixation.
A connection and fixing structure for an aluminum dust cap and a speaker cone in a loudspeaker was designed. By setting a mating ring on the inner wall of the speaker cone, the first stepped surface and the inverted trapezoidal mating surface of the mating ring are used to bond with the dust cap. Combined with an annular limiting groove and an arc-shaped top surface, the contact area is increased to achieve a stable connection.
This improves the bonding strength between the dust cap and the cone, reduces the risk of loosening, increases the yield rate, and facilitates mass production.
