Abstract
The invention provides a welding method of a sounding device, comprising the following steps of: (1): providing a cover plate provided with a first sound aperture and a support frame provided with a second sound aperture, wherein the first sound aperture and the second sound aperture form a sounding aperture when the cover plate is buckled with the support frame; and (2): providing a push rod mechanism, and welding and fixing the cover plate and the support frame, wherein the push rod mechanism supports against the sounding aperture during welding so as to fix the position of the sounding aperture. Compared with the prior art, the invention ensures that the dislocation between the cover plate and the support frame is less than 0.01mm after the welding by accurately positioning the sounding aperture.
Description
[technical field]
The present invention relates to a kind of welding method, relate in particular to a kind of welding method of microphone device.
[background technology]
Mini-sound device is widely used in portable electronic equipments such as mobile phone, notebook computer.Along with fast development, the people of these portable electronic equipments are more and more stronger to its functional requirement, the also corresponding development apace of the mini-sound device that is applied thereon.
The welding method of the microphone device of correlation technique provides the microphone device body, comprises cover plate, support and sound hole on this body, and a described sound hole part is positioned on the cover plate, and another part is positioned on the support; It prevents the sound hole dislocation by product sound hole place is encased, and welds by ultrasonic wave then.
Along with more and more higher to the precision of product technology, the dislocation that requires welding back shroud and support is less than 0.01mm, and the weak point of the welding method of above-mentioned acoustical generator is: cause than big shearing easily, and the dislocation amplitude is much larger than 0.01mm.
[summary of the invention]
The object of the present invention is to provide a kind of welding method of microphone device, can realize the technical purpose of the dislocation of welding back shroud and support less than 0.01mm.
The objective of the invention is to realize like this:
The concrete steps of the welding method of microphone device of the present invention are as follows:
Step 1, the support that the cover plate that is provided with first hole is provided and is provided with rising tone hole, when described cover plate and support are fastened, first hole and rising tone hole formation vocal hole;
Preferably, described transfer bar mechanism comprises push rod and drives the cylinder that push rod moves back and forth.
Preferably, the welding that utilizes ultrasonic wave to carry out cover plate and support is fixed.
Beneficial effect of the present invention is: controlled the dislocation amplitude of welding back shroud and support effectively, made its dislocation less than 0.01mm.

Fig. 1 is the stereogram of microphone device related to the present invention;
Fig. 2 is pack into solid on the support of the sound hole of miniature generating device in the welding method of microphone device of the present invention;
Fig. 3 is a microphone device A of the present invention place enlarged drawing.
[specific embodiment]
The invention will be further described below in conjunction with drawings and embodiments.
The welding method of microphone device of the present invention comprises the steps:
Step 1, provide cover plate 1 that is provided with first hole 10 and the support 2 that is provided with rising tone hole 20, when described cover plate 1 was fastened with support 2, first hole 10 formed vocal holes 3 with rising tone hole 20;
In the welding method of microphone device of the present invention, described transfer bar mechanism 4 comprises push rod 5 and drives the cylinder 6 that push rod 5 moves back and forth; Described transfer bar mechanism 4 comprises that also a groove 7 identical with push rod 5 cross sections and this groove 7 and vocal hole 3 fixed positions communicate.Utilizing ultrasonic wave to carry out cover plate 1 fixes with the welding of support 2.Also can be applicable to outside the ultrasonic wave other welding method; The cylinder 5 that drives push rod 6 is not got rid of other similar assemblies yet.
The present invention is fixing to drive push rod 6 by cylinder 5, withstand fixedly time welding of sound hole 3 at push rod 6, the precision when making the utilization ultrasonic bonding significantly improves, and the dislocation that cover plate 1 and support are 2 is less than 0.01mm, guarantee the quality of product, satisfied the requirement of technological development.
Above-described only is embodiments of the present invention, should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the invention design, can also make improvement, but these all belongs to protection scope of the present invention.
Claims (3)
