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, relate in particular to a kind of earphone horn support laser boring method.
Background technology
The Microspeaker support is meant the horn bracket of size range between 3mm～75mm; Its shape comprises: circular, oval, abnormity, square; Existing Microspeaker support production technology is mainly Shooting Technique (plastic rubber bracket) and Sheet Metal Forming Technology (five metals support), but no matter adopt above-mentioned which kind of technology, all need offer single hole or a plurality of holes in the flanging or the bottom of horn bracket; Be used for regulating the required throughput of Loudspeaker diaphragm vibration processes, and then regulate tonequality.For example, shown in Fig. 6～9, traditional miniature five metals circular horn support (claiming again: iron-clad, iron basin, basin frame) comprises first end 101 and second end 102 that seals of opening; In order to debug damping parameter, utilize cold-punching mould technology, use diel on first end near an end face of second end and/or on second end away from an end face of first end on towards single hole or a plurality of hole 103; Or shown in figure 10,, the conventional square horn bracket dashes has a dorsal pore 104; Because but the aperture in the hole that said method obtains big (general aperture is not less than Φ 0.3mm); Also need further through manual work in loudspeaker unit, fasten with glue damping material (damping material such as adjustable sound paper, screen cloth, adhesive-bonded fabric; Compression cotton etc.) adjust the Frequency Response of loudspeaker, thereby guarantee the tonequality of earphone horn.But because handwork is difficult to realize the uniformity of machine automatic batch processing; The glue consumption that is used to adjust the loudspeaker tone color and applies and the density of damping material etc. also are difficult to precisely controlled; Thereby after causing loudspeaker to paste damping material through coating glue; It is stable to be difficult to be consistent with a collection of earphone horn acoustic characteristic that processes, thereby is difficult to guarantee uniformity in product performance and stability.In order to solve earphone horn tone color problem; Industry also has another one replacement way, promptly on horn bracket, makes a call to a dorsal pore, guarantees that Loudspeaker diaphragm is when the vibration duty; The air of vibration can pass through from this dorsal pore smoothly, to improve the sensual pleasure that the loudspeaker Frequency Response guarantees loudspeaker.
The industry acoustic investigation shows; Characteristics such as sound frequency that people's ear can be discerned and earphone horn tone color determine that this dorsal pore diameter must be not more than Φ 0.15mm on the general earphone horn support; And when plus-minus tolerance can not surpass 0.005mm, the sensual pleasure effect of earphone horn was 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) or the Sheet Metal Forming Technology (five metals support) of horn bracket and can't a step directly make the dorsal pore that has such precision; So when horn bracket dispatched from the factory, general acquiescence was not to be with this dorsal pore.Cause conventional earphone loudspeaker manufacturer generally all to adopt coating glue to paste noise reduction paper and adjust the earphone horn tone color.
Summary of the invention
The objective of the invention is to solve the problems of the technologies described above, a kind of Microspeaker support laser boring method is provided, it utilizes laser that horn bracket is punched; Drilling operation is once accomplished; Drilling operation efficient is high, and drilling precision can be guaranteed, and has reduced production cost.
For reaching this purpose, the present invention adopts following technical scheme:
A kind of Microspeaker support laser boring method adopts laser on horn bracket, to punch, and in order to regulate loudspeaker oscillating plate required elementary cell throughput in vibration processes, is used to regulate tonequality.
Further, horn bracket is passed to laser-beam drilling machine, on horn bracket, gets the hole of regulation by laser-beam drilling machine through autoloader.
Further, laser-beam drilling machine is got the hole of at least one regulation on horn bracket.
Further, laser-beam drilling machine is beaten circular hole or elliptical aperture or profiled holes on horn bracket.
Preferably, first end opening of said horn bracket, second end closure of said horn bracket, said laser-beam drilling machine is in the end face punching of second end closure of said horn bracket.
Preferably, first end opening of said horn bracket, second end closure of said horn bracket, said laser-beam drilling machine is in the sidewall punching of second end of said horn bracket.
Preferably, first end opening of said horn bracket, second end closure of said horn bracket, said laser-beam drilling machine punch with the contacted end face of said second end on first end of said horn bracket.
Compared with prior art, the present invention has following technique effect:
1, because the size of punching on the Microspeaker support is less; Usually the aperture is not more than 0.15mm; Traditional Shooting Technique (plastic rubber bracket) or Sheet Metal Forming Technology (five metals support) can't be accomplished in a step, and the employing laser of the invention property punches to horn bracket, and one step of punching work accomplishes; And can guarantee drilling precision, plus-minus tolerance is no more than 0.005mm;
2, with respect to traditional horn bracket drilling technology; Use machining or mould molding, the aperture is excessive, pastes damping material through manual work coating glue again and adjusts the loudspeaker acoustical quality; The present invention utilizes laser on horn bracket, directly to beat micropore; Reduce raw-material uses such as glue and damping material, reduced manufacturing procedure, saved labor hour; And, improved production efficiency significantly, and guaranteed the stability and the uniformity of loudspeaker Frequency Response and tonequality performance, thereby reduced the loudspeaker processing cost significantly guarantee to have realized batch process under the situation of drilling precision through laser-beam drilling machine.
