主题：[求助]关于SpeaD上喇叭材料的几个问题

谁用过SpeaD模拟喇叭?

Magnet Material, 磁铁等级有Ceramic 5/6/8, 与Y25/30/32/35等有没有对应关系, 或是两种不同的磁铁?

Metal Material, 上下板材质等级Low Carbon Steel 1018/1013/1008含义如何, 哪种更好?我们常用的是哪一种?

Motor Parts

1. From the Menu item Motor Material, select the magnet material Y30 This is a standard Asian material that is roughly equivalent to Ceramic 5.
2. From the Menu item Metal Material, select the metal LCS1013. This is 1013 low carbon steel. It is the most common Asian steel used in loudspeakers.
3. We know from our vendor sheets that the standard magnet dimensions for a 40 Oz magnet are 140 OD x 20 TH x 75 ID. With these, we can estimate that our front and back plate OD should be roughly 10mm smaller in diameter if we are going to use a 10mm Frontplate. This means a Plate OD of 130 mm.

4. From the Frontplate Outside Dia. drop down box select 130.
5. From the Frontplate thickness drop down box select 10. (Notice that there are two parts with a 130mm OD because the thickness box shows both 8 and 10mm available.)
6. Click on the Voice Coil Active Label Information by running the mouse over the label and clicking when you see a highlight box appear. If you hold the mouse down you will see additional information about the voice coil design including a Recommended Front Plate Inside Diameter. The ID that it recommends is 54.4mm.

7. In Frontplate Inside Diameter type 54.4 (Or select it from the drop down box) <Enter>
8. Enter the dimensions that we already know for a 40 Oz magnet in the appropriate boxes under magnet (140 OD, 20 Thickness, 75 ID)
9. We already know that the OD of the metal parts will be 130 so from the Backplate Outside Dia. drop down box select 130 <Enter>
10. It is common to match the plate thickness so select 10mm for the Backplate thickness. <Enter>

11. The gap between Pole OD and Voice Coil ID is typically set by the manufacturer to allow clearance for production and a small amount of yaw at high levels. The Standard amount usually runs about .3mm on this size coil so the Pole OD should be .6mm smaller then the Voice Coil ID. This would be 48.95mm. Enter this value for Pole Diameter. <Enter>
12. For now we will leave the pole extension at the default of 0.
13. Using the drop down box on Vent hole diameter select 25mm <Enter>

14. The motor design should now be complete and you can go to the Motor Parts Active Label for more information including Bg. You can also see the percentage saturation for the metal parts by pressing the colored bars under each part.

鬼佬老板才给了我一套SpeaD/Reverse,我就试用一下, 我是搞不清楚Magnet Material和Metal Material的等级与实际中用的怎么去对应.

平时只知道Y25/30....;那Ceramic 5/6/8又是怎么一回事; 平时用的T铁和华司,各位有向供应商要 1018/ 1013/ 1008这样等级证明吗?

DEEGC即东磁!

HITACHI是日立!

the magnet material Y30 This is a standard Asian material that is roughly equivalent to Ceramic 5.
一是东磁牌号(Y30)

另一是日立牌号(Ceramic 5)

This is 1013 low carbon steel. It is the most common Asian steel used in loudspeakers.
国内常用低碳钢(估计类似A3钢)

Metal Material
The Metal used in the Frontplate, Backplate, and Pole piece can have a substantial effect on the overall performance of a speaker. SpeaD can model virtually any material by way of its Metal libraries. Typically speakers in the US are built with 1018 Low carbon steel. (Asian parts use 1013 steel). The carbon content in the steel determines the magnetic characteristics. Generally, lower levels of carbon yield higher Magnet strength. SpeaD has models for many common materials. The SpeaD website will be constantly updating the material libraries which can be placed in the Material Library folder.

Typically speakers in the US are built with 1018 Low carbon steel.美国常用1018低碳钢

ALPHA不知是哪家公司?

这里可以直接下载材料数据!

用SPEAD加上词霸全部都可以搞定了，何必笨呢？？？？？？？？？？

哎，兄弟偶就这样笨过， 笨，早知道抛个几k出来，请个翻译伺候了.....

词霸翻译不出DMEGC

还有很多都翻译不出来的!!!

是啊,很多专业词汇都翻译不准!

FEMM里面的材料库要少些,名称类似.

谁有材料库的TXT文档?如磁性材料和导磁材料的?

Cone Fo
The cone Fo is the standard compliance measurements for cones and edges. It is available from cone suppliers or can be measured using a standard Fo analyzer. It is important this measurement be taken under the same conditions that the speaker will be tested. Temperature and humidity can cause dramatic changes in this test because of the relative instability of rubber and foam typically used for edge material and moisture retaining cone materials such as untreated paper. This measurement is difficult to make accurately for very high compliance materials such as butyl or santoprene edge. Unsecured clamping around the entire edge, sag, and conflicting resonance of the driving speaker can all contribute to errors in this test

Sd
The cone area of the speaker. This is defined by measuring from the diameter from the inside 1/3 of the edge roll, and then calculating area.

Acoustics说得完全正确，我查了一下FEMM软件库中关于CERAMIC 5的参数是：

Br=0。394T，Hcb=191KA/m，再对照东磁关于DM30的定义：Br》0。38T，Hcb》184KA/m，就很明白了，

至于1008，1013等称号是指含碳量 8/1000，13/1000，都是低碳钢
