Abstract
The invention discloses a laser drilling method for miniature loudspeaker brackets. The method is characterized in that through drilling holes on a miniature loudspeaker bracket by using laser, the required basic unit air flow quantity of a loudspeaker vibrating plate in the process of vibrating is adjusted, and then the tone quality is regulated. According to the invention, through creatively using the cooperation of a laser drilling machine and an automatic feeding machine, micropores are drilled on a miniature loudspeaker bracket, so that compared with the traditional loudspeaker bracket drilling process which is implemented through using mechanical processing or die forming, so that the pore diameter is overlarge, and then manually coating glue for adhering damping materials so as to adjust the sound effect of a loudspeaker, the method disclosed by the invention can be used for reducing the application of raw materials such as loudspeaker glue and damping materials, reducing the processing process, and saving the artificial time; and under the condition of guaranteeing the accuracy of drilling through a laser drilling machine, an effect of batch production is achieved, the production efficiency is obviously improved, and the stability and consistency of frequency response characteristics and tone quality performances of a loudspeaker are ensured, thereby significantly reducing the processing cost of the loudspeaker.
Description
Technical field
The present invention relates to a kind of Microspeaker support drilling technology, particularly relate to a kind of earphone horn support laser boring method.
Background technology
Microspeaker support refers to the horn bracket of size range between 3mm ~ 75mm, its shape comprises: circular, oval, special-shaped, square, existing Microspeaker support production technology is mainly Shooting Technique (plastic rubber bracket) and Sheet Metal Forming Technology (hardware bracket), but no matter adopt which kind of technique above-mentioned, all need to offer single hole or multiple hole at the flanging of horn bracket or bottom, for regulating throughput required in Loudspeaker diaphragm vibration processes, and then regulate tonequality.Such as, as shown in Fig. 6 ~ 9, the miniature five metals circular horn support of tradition (also known as: iron-clad, iron basin, frame) comprise the first end 101 of opening and the second end 102 of sealing, in order to debug damping parameter, utilize cold-punching mould technology, use diel on first end near an end face of the second end and/or on the second end away from the single hole of end face upper punch or a multiple hole 103 of first end, or as shown in Figure 10, , traditional square horn support punching has a dorsal pore 104, but due to the aperture comparatively large (general aperture is not less than Φ 0.3mm) in the hole that said method obtains, also need further by manually fastening with glue in loudspeaker unit that (damping material is as adjustable sound paper for damping material, screen cloth, adhesive-bonded fabric, compression cotton etc.) adjust the Frequency Response of loudspeaker, thus ensure the tonequality of earphone horn.But because handwork is difficult to the uniformity realizing the processing of machine automatic batch, the glue quantity applied for adjusting loudspeaker tone color and the density etc. of damping material are also difficult to precisely controlled, thus cause loudspeaker to paste after damping material through glue coating, be difficult to be consistent with a collection of earphone horn acoustic characteristic processed stable, thus be difficult to the uniformity and the stability that ensure properties of product.In order to solve earphone horn tone color problem, industry also has another one to replace way, on horn bracket, namely make a call to a dorsal pore, ensures that Loudspeaker diaphragm is when vibrating duty, the air of vibration can pass through smoothly, to improve loudspeaker Frequency Response to ensure the sensual pleasure of loudspeaker from this dorsal pore.
Industry acoustic investigation shows, the characteristics such as the sound frequency that people's ear can identify and earphone horn tone color determine that on general earphone horn support, this dorsal pore diameter must be not more than Φ 0.15mm, and plus-minus tolerance can not more than 0.005mm time, the sensual pleasure effect of earphone horn is just qualified.But because the aperture of Φ 0.15mm is too little, and the tolerance grade of positive and negative 0.005mm requires also very high, produce the Shooting Technique (plastic rubber bracket) of horn bracket or Sheet Metal Forming Technology (hardware bracket) and a step cannot directly make dorsal pore with such precision, so when horn bracket dispatches from the factory, general acquiescence is not with this dorsal pore.Conventional earphone loudspeaker manufacturer is caused generally all to adopt glue coating to paste noise reduction paper to adjust earphone horn tone color.
Summary of the invention
The object of the invention is to solve the problems of the technologies described above, provide a kind of Microspeaker support laser boring method, it utilizes laser to punch to horn bracket, drilling operation once completes, drilling operation efficiency is high, and drilling precision can be guaranteed, and reduces production cost.
For reaching this object, the present invention by the following technical solutions:
A kind of Microspeaker support laser boring method, adopt laser to punch on horn bracket, laser aperture is not more than 0.15mm, and plus-minus tolerance is no more than 0.005mm, in order to the elementary cell throughput regulating loudspeaker oscillating plate required in vibration processes, for regulating tonequality.
Further, by autoloader, horn bracket is passed to laser-beam drilling machine, on horn bracket, is got the hole of regulation by laser-beam drilling machine.
Further, the hole of at least one regulation got by laser-beam drilling machine on horn bracket.
Further, laser-beam drilling machine beats circular hole or elliptical aperture or profiled holes on horn bracket.
Preferably, the first end opening of described horn bracket, the second end closure of described horn bracket, described laser-beam drilling machine punches at the end face of the second end closure of described horn bracket.
Preferably, the first end opening of described horn bracket, the second end closure of described horn bracket, described laser-beam drilling machine punches at the sidewall of the second end of described horn bracket.
Preferably, the first end opening of described horn bracket, the second end closure of described horn bracket, the end face that described laser-beam drilling machine contacts with described second end on the first end of described horn bracket punches.
Compared with prior art, the present invention has following technique effect:
1, because size that Microspeaker support punches is less, usual aperture is not more than 0.15mm, traditional Shooting Technique (plastic rubber bracket) or Sheet Metal Forming Technology (hardware bracket) cannot a step complete, the employing laser of the invention punches to horn bracket, punching work one step completes, and can drilling precision be ensured, plus-minus tolerance is no more than 0.005mm;
2, relative to traditional horn bracket drilling technology, use machining or mould molding, aperture is excessive, paste damping material by manual application's glue again and adjust tone quality of horn effect, the present invention utilizes laser directly to beat micropore on horn bracket, decrease the raw-material use such as glue and damping material, decrease manufacturing procedure, save labor hour; And when ensureing drilling precision by laser-beam drilling machine, achieving batch production, considerably improving production efficiency, and ensure that stability and the uniformity of loudspeaker Frequency Response and tonequality performance, thus decreasing loudspeaker processing cost significantly.
