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

Example Embodiment

[0052] See Figure 4 , The present invention provides a method for manufacturing a miniature speaker, which includes the following steps:

[0053] (a) First, prepare a jig 1 and a jig upper cover 2 (such as Figure 5 (Shown), the top surface of the jig 1 is protrudingly provided with a circular flange 11, a circular accommodating space 12 is opened inside the flange 11, and a supporting seat 13 is protrudingly provided at the center of the accommodating space 12, The top surface of the supporting seat 13 forms a curved surface; the bottom surface of the upper cover 2 of the fixture is formed with a groove 21 corresponding to the flange 11, and a circular first through hole 22 and a conical shape are provided on the groove 21 The second perforation 23;

[0054] (b) Then an apron 3 made of plastic material is placed in the accommodating space 12 of the jig 1 (as shown in FIG. 6), and the apron 3 is placed in the accommodating space 12 in an inverted state, The rubber ring 3 is a cir...

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...
