[0002] Among the common speaker products currently on the market, the method of fixing the speaker component to the front cover shell by double-sided adhesive is a relatively common solution, which mainly includes the following steps: the first step is to take a double-sided adhesive and put it on the tooling, and tear off the outermost circle of glossy paper on the double-sided adhesive; the second step is to put the front cover shell on the tooling and press it tightly; the third step is to remove the front cover shell and tear off the excess double-sided adhesive; the fourth step is to put the speaker component welding piece on the front cover shell with the outside facing outward, and press it tightly by hand to complete the assembly and fixation of the speaker component. The tooling design adopted can ensure that the bonding is in place and the assembly direction of the speaker component is accurate.
