一体结构扬声器导磁座及其加工法Integral structure loudspeaker magnetic base and its processing method

技术领域technical field

本发明涉及一种扬声器导磁座及其加工法，特别是一种由此加工法可使扬声器导磁座形成一体结构的制作手段，即一体结构扬声器导磁座及其加工法。The invention relates to a loudspeaker magnetic base and a processing method thereof, in particular to a manufacturing method which enables the loudspeaker magnetic base to form an integrated structure through the processing method, that is, a loudspeaker magnetic base with an integrated structure and a processing method thereof.

背景技术Background technique

扬声器导磁座为决定扬声器性能的关键组件之一，而该扬声器导磁座内必需要开设一深沟窄槽的环形槽，以供振动膜位移作动，而因为在扬声器导磁座上开设深5mm～10mm，宽1.6mm～3.0mm的深沟窄槽，是传统加工方法的瓶颈，故传统扬声器导磁座(请参阅图1及图2所示)多以二件式方式制成，其分为内、外座体二部分来分别制作完成后，再将二者利用适当的结合手段结合成一体，并利用内、外座体直径大小的差异，来形成环形槽。The magnetic base of the speaker is one of the key components that determine the performance of the speaker, and an annular groove with a deep groove and narrow groove must be opened in the magnetic base of the speaker for the displacement of the diaphragm, and because the magnetic base of the speaker is set Deep and narrow grooves with a depth of 5mm to 10mm and a width of 1.6mm to 3.0mm are the bottleneck of traditional processing methods. Therefore, traditional speaker magnetic seats (see Figure 1 and Figure 2) are mostly made in two pieces. It is divided into two parts, the inner and the outer base body, and after being manufactured respectively, the two parts are combined into one body by appropriate means of combination, and the difference in diameter between the inner and outer base bodies is used to form an annular groove.

然而使用此种方式制作的扬声器导磁座，因结合手段多利用铆合的方式，其不但制作速度慢、成本高，且其二铆合件的间必定存有间隙，而该间隙会导致导磁率降低，进而影响扬声器性能。因此，若能消除间隙，便可提高导磁率，更而提高扬声器的性能。However, the magnetic permeable seat of the loudspeaker made in this way is usually riveted, which not only has slow production speed and high cost, but also has a gap between the two riveted parts, and this gap will lead to The magnetic rate is reduced, which in turn affects speaker performance. Therefore, if the gap can be eliminated, the magnetic permeability can be improved, and the performance of the speaker can be improved.

As shown in the figure, the above-mentioned monolithic loudspeaker magnetic permeable seat is made using the following manufacturing and processing method, which is mainly completed by two steps. First Forming step a, followed by cutting step b to form an integrated speaker magnetic seat; wherein,

成型步骤a：以适当手段制作预定座体1态样；该适当手段，可以锻造或冲压成型或其它等效的成型方法。Forming step a: making a predetermined shape of theseat body 1 by appropriate means; the appropriate means can be forging or stamping or other equivalent forming methods.

切削步骤b：以适当的工具于座体1内进行环状切削，使该座体1内具有一窄沟深槽的环形槽5，并让该座体1中央形成有一柱状体13，该柱状体13便与座体内壁面11保有环形槽5宽度间距，以使套设于扬声器导磁座1柱状体13上的振动膜(图中未示)，借助该环形槽5及柱状体13可轴向作动。Cutting step b: Carry out annular cutting in theseat body 1 with an appropriate tool, so that there is an annular groove 5 with a narrow groove and deep groove in theseat body 1, and acolumnar body 13 is formed in the center of theseat body 1, thecolumnar body Body 13 just keeps annular groove 5 width intervals with seatinner wall surface 11, so that the vibrating membrane (not shown) that is sleeved on the loudspeaker magneticpermeable seat 1columnar body 13 can be axially moved by means of the annular groove 5 andcolumnar body 13 To move.

另外，该切削步骤a中所述的工具为一于密闭外方空间内，仍可以排出切削废屑的切割刀，该切割刀设计有一具适当斜角的刀刃，用以引导切削过程中的废屑，向切割刀内集中，并经由其上所设计的贯穿孔道而将废屑排出，因此，依本加工法再配合可于密闭外方空间中排屑的切割刀，即可制作一体结构的扬声器导磁座，而借助此种方法制成的扬声器导磁座，于座体1的密闭凹入空间3内，一次切削完成窄沟深槽的环形槽5，如此可使整个座体为一体完成的单件形式，无传统制法扬声器导磁座有接合间隙的缺点，且更可使导磁效率达到100％，以有效提高效能。In addition, the tool described in the cutting step a is a cutting knife that can still discharge cutting waste in a closed external space.
