Abstract

A preparing method for a minitype sounder includes concrete steps as following: a, providing a sounder body with a conduction end at one end; b, providing an elastic part and a bracket with a positioning hole, the elastic part is inserted on the bracket through the positioning hole; c, arranging the bracket with the elastic part on the sounder body, and leading the elastic part to be butt connected at the conduction end of the sounder body; d, utilizing ultrasonic welding technology to weld the bracket on the sounder body. The preparing method of the invention can stably connected the minitype sounder with the outside circuit.

Description

【Technical field】 [0001] The invention relates to a manufacturing method of a miniature sound-generating device. 【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] Micro sound-generating devices are used to complete the conversion between electrical energy and sound energy, such as speakers, receivers and other sound-generating devices to complete the conversion of electrical energy into sound energy. In order to realize the conversion between electric energy and sound energy, the sound-generating devices need to be connected to external circuits, and the connection methods of circuit input or output usually include sever...
