Abstract

The invention discloses a method for making a micro sounding device. The method comprises the following steps of: spreading a layer of hot melt glue on a limit frame of an upper cover; positioning a diaphragm positioning frame on the limit frame of the upper cover; heating the upper cover to melt the solidified hot melt glue and then cooling the upper cover to solidify the hot melt glue in order to adhere the peripheries of the upper cover and the diaphragm tightly. The method for making the micro sounding device makes the peripheries of the upper cover and the diaphragm tightly connected together, without causing the pollution of the glue to the diaphragm, thereby improving the performance of products.

Description

technical field [0001] The invention relates to a manufacturing method of a micro-sounding device, in particular to a process method for bonding the diaphragm of the micro-sounding device to the periphery of an upper cover. Background technique [0002] Miniature sound generating devices are widely used in portable electronic devices such as mobile phones and notebook computers. With the rapid development of these portable electronic devices, people's functional requirements are getting stronger and stronger, and the miniature sound-generating devices applied to them are also developing correspondingly and rapidly. [0003] Please refer to figure 1 , the micro-moving-coil sounding device 2 of related structure comprises a lower casing 21', an upper cover 26' connected to the lower casing 21' and provided with a sound hole 261', a magnetic bowl accommodated in the lower casing 21' 22', a diaphragm 25'. The front side of the diaphragm 25' and the upper cover form a front ca...
