Abstract

The invention provides a manufacturing method of a minitype acoustical generator, comprising the following steps: providing a base with a bonding pad, a vibrating diaphragm and a voice coil with a voice coil wire; connecting the vibrating diaphragm with the voice coil together; spreading glue on the base, and placing the vibrating diaphragm and the voice which are together connected on the base so that the vibrating diaphragm is connected with the base; welding the voice coil line on the bonding pad of the base in a spot way; drying and solidifying the glue spread on the base with high temperature; spreading the glue on the connecting part between the vibrating diaphragm and the base; and drying and solidifying the glue spread on the base with high temperature. The method can reduce the low frequency distortion.

Description

technical field [0001] The invention relates to a manufacturing method of a miniature sounder. Background technique [0002] Miniature sound generators are widely used in portable electronic devices such as mobile phones, notebook computers, and hearing aids. 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] The micro-sounding device of the related structure mainly includes a bowl-shaped base, an upper cover connected to the base and provided with a sound hole, and the base and the upper cover form a receiving cavity. The accommodating cavity is provided with a permanent magnet and a pole piece housed in the base and forming a magnetic gap with the base, a diaphragm adjacent to the upper cover, a voice coil connected with the diaphragm and suspended in the magnetic gap, A circ...
