Abstract
The instant disclosure relates to a manufacturing method of a sound playing assembly for micro-sized speaker. The method includes the following steps: providing a carrier having a strip-shaped grill member; cutting the carrier after it has been transferred into a cutting unit to obtain a trimmed grill member; transferring the trimmed grill member onto a machine plate; and performing injection molding with molten plastic after the trimmed grill member is transferred from the machine plate into a mold by a material handling equipment, in order to form a seat body having a speaker basket surrounding the trimmed grill member, with the speaker basket partially embedded in the grid structure of the trimmed grill member.The trimmed grill member and the seat body are thus formed integrally in providing a sound playing assembly. The assembly can help to improve production yield rate and be mass-produced in an automated process.
