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?
东磁现已具备年产10万吨永磁预烧料和年产8.5万吨永磁铁氧体、3万吨软磁铁氧体的生产能力,是世界第一永磁预烧料和永磁铁氧体生产基地,是全国最大的软磁铁氧体生产基地。公司自1993年开始自营办理出口业务,有80%的产品出口到日本、美国、韩国、东南亚等四十多个国家和地区,仅2004年公司实现销售收入27.53亿元,全年完成出口交货值19.5亿元,其中自营出口创汇突破7100万美元,创利税3.8亿元。名列2004年第十七届中国电子元件百强企业第5名,第十八届全国电子信息百强企业第51名。
东磁从1987年开始全面推行TQC工作,建立健全了质量管理体系。是全国磁性行业中首家通过ISO9002质量体系认证和QS9000质量体系认证的企业。2000年12月被国家农业部授予“国家乡镇企业质量管理先进单位”称号。99年12月,经国家人事部批准建立了全国磁性行业第一座国家级博士后科研工作站,为东磁高科技项目的开拓打下了坚实的基础。2000年,东磁被国家农业部评为全国乡镇企业创名牌重点企业。并被省人民政府命名为首批排头兵企业和管理示范企业。2004年东磁公司近年来加大了科研开发的力度,不惜代价引进国内外技术权威人士、博士后、高级工程师等高品位工程技术人员从事磁性材料等新技术、新工艺的研究。目前,由我公司开发成功的抗干扰磁芯、高性能电机磁瓦、微波炉磁体等产品已形成大批量生产,其中微波炉磁体是国内唯一能生产的厂家,产量已超过世界总量的60%。

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.

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.....
还有很多都翻译不出来的!!!

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?
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,
