劳驾大虾帮忙计算箱体容积并设计分频器，二分频导向式 [复制链接]

没办法，都发不出。晚点再给你发过去好了，抱歉。

30-2是一款很不错的单元，用的好会给你贵丽的音色，单体灵敏度高音色细腻及瞬态响应极好，全归功于它的小音圈结构（从其振膜型状可看出）。但这种单元一般不太好搞，更强调整体设计。我建议你先确定心怡的音色，再谈做箱子。因为音箱设计并不能简单的公式化，没有简单的最优化设计，同样不可以量化的。想得到怎样的效果，设计手段大相径庭。

难！
如果你决心已定，他是你唯一的选择，并且在你的银子允许的范围没有更好的选择，接下来你可以购置单元。
购置好单元后第一步测量单元的频响同实际阻抗，并与厂方提供的频响比较，明确差距，应有初步的设计方案。
运用电脑模拟设计，并根据实际频响同阻抗校正。倒相管参数本人认为电脑模拟非常准确，但仍然需要适量调整。
制造音箱原型，并测量与电脑模拟是否一致，特别是实际听感是否符合你的要求，反复数十次微调整分频器及倒相管，甚至于要有大胆的创造性，这样你才能得到你想要的东西。但他只能适用于你特定的箱子。

For the sealed box, with the help of the T/S parameter, you can
choose the dimensions of the box to decide the Q of the box.

So, you must get the rest of the parameter to start calculating
the box !!!!!

Why don't you call the manufacturers by phone to ask them.
I am sure they will be happy to tell you or otherwise ask them to
give you their suggested design.

Dangerous to look at the shape of the driver to design the box.
Well otherwise there won't be T/S parameter for the speaker
design.

Speaker box design now mostly based on the T/S parameter
( Thiel & Small ) that some essential data is a must for designing
a speaker box.

It is also true that after calculation, there are so many options for
the designer to determine such as the Q of the box, the
diameter and the length of the vent ( for vented box ) that would
affect the noise level of the air flow.

The calculation would also calculate this air velocity when you
decided the diameter of the duct (vent). Exceeding this limit
will result air flow noise as when the woofer is in action, there
are air flowing in and out the duct, the thinner the duct, the
higher the air velocity.

However, the diameter of the duct is so designed not to exceed
say the velocity of 0.3 Mark  ( Mark is the unit of air velocity) to
be a common practice on speaker design but not look at the
shape of the driver and design.

It's a pity that Boeing cannot provide those T/S parameter to
otherwise it is easy to design a box for him.

Upon finishing the box, then the tweaking come afterward
such as how many cotton fibre to put into the box will take time
to experiment. The caps and the coil of the crossover can also
be the parts to be try and error.

Boeing, I can tell you there will be a lot hard work if you went
wrong at the first place.

So don't listen to some people said look at the cone, look at
the voice coil then design your bos.

If so, please ask them how to start????

仪器都备齐了吗？详细的测试方法，资料一下找不着。不知你的动手能力如何？如果对这方面了解不够的话，不好说。谢谢。

多谢“开心果”：）
煲喇叭我还真的没有想过直接接功放上的办法，好！！！
测试方法呢功能再详细的说一下吗？我一直不知道究竟是怎样做的，多谢了！
没有人能对分频器给出一些意见吗？资料都在老家，现买也找不到……

回开心果：
我想我的动手能力还是可以的，从CD机到音箱包括线材我都曾经自治过。我是学航空机械的，电子方面很多都是知道的比较肤浅，但我想你把大致的方法告诉我还是差不多的。
仪器和工具我们单位有一部分，估计信号发生器不易搞定不知道能否借到。但我还是想知道具体的测试方法的。一起只是听说自己可以测量.
回madog：
我现在只能知道上面附图的一些参数，其他要问厂家，很困难。
Qms是等效震动质量吗？Qes是什么？不好意思：（
以前似乎见过这两个参数，但三年多没玩了，已经忘的差不多了。
多谢了：）

Hi Boing,

Give me more detail parameter such as the diameter of the
woofer and others, Qms, Qes, and will give you the box design
and x'over design.
