[0002] As a sound-generating body, each component of the speaker must be tightly combined, otherwise the speaker will sound abnormal or even unusable. The installation of each component of the speaker requires accurate installation position and firm combination of components, especially the bonding between the basin frame and other accessories; the existing speaker basin frame often needs to be glued by a glue dispensing device when dispensing glue, and the basin frame is glued around by rotating the glue dispensing tube for one circle, and then the basin frame and other components are bonded. However, this structure often requires the glue dispensing tube to rotate one circle each time it is glued, and the glue dispensing operation efficiency is low. Moreover, the glue dispensing tube needs to add glue frequently, and the operation is cumbersome. In addition, the diameters of different basin frames are often different, so the glue dispensing rotation radius of the glue dispensing tube is also different.
