Micro loudspeaker production method and device thereof

Abstract

The invention relates to a minitype loudspeaker manufacturing method and device, which includes: a rubber gasket is put in a fixture capacity space, the rubber gasket has a joint part inside; a vibrating film periphery is bonded with the rubber gasket joint part; a voice coil is located in the vibrating film single-surface concentric position by the fixture upper cover, and the voice coil is bonded with the vibrating film, the rubber gasket, vibrating film and voice coil constitute a voice-half combination; a shell-half combination combines with said voice-half combination. The voice-half combination assembly and combination with the voice-half combination and shell-half combination are processed by using same fixture. The voice-half combination is not need to took off from the fixture after assembly, and can combine with the shell-half combination directly. The fixture amount is reduced and operation flow is consistent, productivity effect is increased, cost is reduced and coaxiality problem is not to occur.

Description

technical field [0001] The invention relates to a manufacturing method of a micro-speaker and its device, in particular to a manufacturing method of a micro-speaker and a device thereof which do not require a copper ring for the half-tone combination and can reduce manufacturing costs. Background technique [0002] Speakers can be installed on earphones or various electronic devices (such as translators, mobile phones, PDAs and notebook computers, etc.) to emit sound. With the demand for thinner, lighter and smaller electronic devices, the application of micro-speakers is becoming more and more extensive. [0003] see figure 1 , the known miniature loudspeaker comprises a tone and a half combination 1a and a shell and a half combination 2a, and the tone and half combination 1a includes a vibrating membrane 11a, a copper coil 12a and a voice coil 13a (such as figure 2 As shown) the thickness of the vibrating membrane 11a is about 6 μm-9 μm. Since the vibrating membrane 11a...

Problems solved by technology

[0006] However, in the above-mentioned known microspeakers, the vibrating membrane 11a must be supported by a copper ring 12a, the copper ring 12a is made of copper, and the price of copper is relatively high, resulting in an increase in manufacturing cost.

[0007] Furthermore, the tone-half combination 1a and the shell-half combination 2a need to be produced separately, so the tone-half combination 1a and the shell-half combination 2a need to use two kinds of jigs, which are divided into two processes and made separately. Combination 2a is made separately and after the glue dries, another jig can be used for the subsequent adhesive bonding of tone-half combination 1a and shell-half combination 2a. Therefore, multiple jigs are required, and the operation process cannot be consistent, which is labor-intensive. Time-consuming, which reduces the production efficiency and increases the cost, and the sound-half combination 1a and the shell-half combination 2a are produced separately, and there will be concentricity problems when combining, causing inconvenience in operation
