简介:DIY TINFOIL带扬声器

关于:另外另一个Tinkerer

大家好,

在这种说明中,我想与您分享如何制作一个简单的带型扬声器作为带状膜片。

我开始这个项目,看看丝带驱动程序设计是否可以成为我在建造的一些带耳机的可行候选人。

They can also be used for a high frequency driver instead of a regular tweeter.

我收到的结果大大超出了我的期望。

加入我的创造这些......


什么是丝带扬声器?


"These speakers are based on the same principle as cone speakers, i.e. the interaction of the magnetic field of a magnet with that of a wire through which the signal coming from the amp passes. However, the wire is not coiled around a cylinder extending from the diaphragm. The diaphragm itself is the signal conductor, taking the form of a rectangle held by two of its sides. The electronic circuit is drawn on top, trying to spread it as evenly as possible so that the magnetic force is uniform. The fact that the voice coil and the diaphragm are combined in a single piece makes the moving section lighter, thus avoiding, at least in theory, the displacement of the diaphragm. The conductor is spread across the entire surface, exercising a more homogeneous motive power than a voice coil which has to drive a cone at one end." - audiofanzine.com

第1步:你需要什么:

要复制此说明,您需要以下内容:

- 访问3D打印机。

- ~5m 3D printing filament.

- 一块新的Lightduty Tinoil,没有很多折痕。

- 6x 10mmx3mm圆形钕磁铁(这可以是其他形状和尺寸,但打印支架需要改变)

- 带粘合剂的6mm铜箔带。

- 2部分CA胶或2份环氧树脂。

- 具有相当侵略性的牙齿的宽齿轮。(可用3D可打印文件)

- 一些扬声器线。

- Soldering iron.

- 焊料。

- 一个非常锋利的爱好刀具。

- Foam art sheet or soft rubber sheet

- 一些蓝钉。*

- 要驱动扬声器,您需要一个合适的变压器或串联电阻,我在测试中使用了5欧姆40W电阻(链接到来)

第2步:3D打印:

首先,我们需要获得印刷扬声器的主体。

我使用融合360设计了它,可以很容易地修改为使用不同的磁铁或改变扬声器的尺寸。

Moving forward for using these as headphone drivers I will alter the design to fit lower profile bar magnets so that I can reduce the overall thickness and i'd duplicate and merge the design so that there are two speakers next to each other.

我还制作了一个快速的喇叭/波指南,看看它是否会对体积产生重大影响,但是对于预期用途,我决定抛弃它。

一切都印刷在ABS长丝中,以避免从焊接热中的任何变形。但PLA和PETG灯丝也将有效。

用0.28层高度打印.6mm喷嘴。

Step 3: Assembling the Magnets:

现在我们打印了主体,我们可以开始组装磁铁。

Orientation of the magnets inside the body is very important, if one of the magnets is not facing the correct way it will cause major issues with the sound.

开始我彼此顶部堆叠所有磁铁,以便我知道他们都面临正确的方式,

然后你想拿一个标记并标记每个磁铁的顶部,确保不要在你去时翻过来。

接下来我将印刷部分放在金属桌上的侧面,这将使磁铁保持在胶合时,现在在身体一侧的每个凹痕中添加一滴胶水并将磁铁滑入每个缩进,您在磁铁上制作的标记应该面朝上。

现在,如果您使用的是CA胶水,您可以给它一个激活剂的喷雾,现在您可以将其翻转并在另一侧的磁铁中胶水。这次磁铁上的标记需要面向下方。

随着他们的所有磁铁,我拿了一个备用磁铁,只需双重检查,所有磁铁都面向正确的方向,然后我刚刚在所有磁铁中添加了一层胶水,以确保它们不会松动如果它确实会摧毁隔膜。

第4步:组装电气连接:

我做了很多思考如何在箔和扬声器线之间产生电气连接。

使用铜胶带似乎是最简单的方法,它平坦,所以非常脆弱的锡箔堆积在没有扭曲的情况下,已经有一个粘合剂背衬,这使得玻璃玻璃使其成为优异的导体和易于焊接。

All I had to do was cut off a strip of about 5cm and wrap it around each side of the main body as shown in the picture.

容易!

第5步:制造锡箔带状膜片:

首先将你的锡箔放在平坦的切割表面上,然后使用新的锋利的爱好刀切断距离主体的中心槽(13-14mm宽)和约10厘米较长的条带。

I suggest cutting a few as forming the ribbon may take a few tries .

Next I went through my box of salvaged gears to find one that is wider than the strip of foil and has an aggressive tooth profile that would create a nice deep crease in the tinfoil.

编辑:包括用于使用的3D可打印齿轮


现在在泡沫/橡胶板上铺设一条烟灰,并开始从一侧滚动齿轮,以足够的压力造成较深的折痕,小心不要撕裂箔。齿轮上的不均匀压力趋于使箔片曲线弯曲到侧面,它花了3次试图,直到我甚至甚至是脱条。

Step 6: Assembling the Tinfoil Diaphragm:

既然你有一个形成的锡箔带,我们可以将它连接到主体。

I had to do this step twice as the first time I just attached it directly to the main body, this caused a distortion at higher volume as the ribbon started to vibrate against the hard plastic.

为了停止这种情况,我涂抹了一小位的蓝色钉在缎带迎合主体的角落里,这会立即解决问题并收紧声音。

切割你制作〜65-70mm的缎带(如果你没有改变主体的尺寸)

要将带状带连接到主体上,我将铜带的小平方加到带子的每个端部,然后将带子粘在主体的中心,如图所示。

你想向功能区添加轻微的张力,但并不像展开你所做的折痕。

幸运的是,丝带永远不会完全连接到主体(它只被两端的铜带保持),所以如果损坏,它很容易更换。

If you have a multimeter it would be a good idea just to make sure you have an electrical connection between the ribbon and the copper tape on the main body.

第7步:焊接:

The only thing left to do is solder on the speaker wires!

因为我们在塑料上焊接,我让烙铁完全加热,增加了铜带的良好通量,然后在电线的每一侧迅速放置一块焊料。

等待the for the places to cool down and then tin your speaker wires and quickly solder them to the main body.

..............现在时间来了

第8步:享受!

Now you can sit back and enjoy your creation...

由于带扬声器具有非常低的阻抗,因此您需要阻抗匹配变压器或合适的电阻,以将其连接到放大器。

不幸的是,我还在等待变压器到达,所以我必须使用电阻,使用电阻对扬声器的输出有很大的负面影响,因此我强烈建议在制作时获得合适的变压器。

The sound really surprised me, I knew they were going to sound clear and open but I did not expect the amount of bass I got too. They are really nice full sounding drivers and I think will make excellent headphone drivers!

YouTube视频是扬声器播放的声音剪辑,它们对人们的声音更好,因为只难以在手机麦克风上录制低音量音频。

我希望你们喜欢这个指导并与我分享你的创作。


幸福的制作!

    非常酷的项目,我喜欢它。关于变压器,我认为可以使用低阻抗变压器偶像4欧姆,输出0.5欧姆。我知道它没有突出,但如果你反弹一个旧的,你会得到它。因为我不会做到,我将分享它是如何的。

    你的胶合板DML已经成为我的日常司机。我很喜欢高端音频!所以,非常感谢你。我希望这个项目带我到新的高度,但请告诉我们更多关于“阻抗匹配变压器”的信息,请。

    About transformers: to my knowledge, they transfer power differently at different frequencies. Won't a transformer introduce distortions?

    正确,高质量的音频变压器至少保持这些扭曲,但否则您使用电阻,但这会降低您的输出,或者您必须使较长的色带/系列连接以增加阻抗。

    该装置具有非常低的阻抗,几毫米,因此需要大量的电流进行驱动,因此许多AMPS标准放大器无法提供。具有4或8欧姆输入阻抗的变压器和非常小的输出阻抗,能够提供这样的电流,并且当然可以尽可能短的输出连接。

    伟大的指导。写得良好和执行。我不是一个听觉,并且没有看到“司机”这个词在这里使用。我认为司机是能够为别的东西提供权力。驾驶员可能是例如前置放大阶段。在这里,似乎您正在呼叫音频传感器,驱动程序。没关系,这是一个很棒的项目。

    Nicely detailed! I'm unclear on just what is 'blue tack'. Also, does the adhesive side of the copper tape also conduct? (is the adhesive conductive) and that is why it connects to the foil?

    你好,
    铜带的粘合剂侧不导电,这就是我首先将铜带围绕主体覆盖的原因,使得导电铜侧与箔带的下侧接触。
    As for the blu tack:https://en.wikipedia.org/wiki/blu_tack.希望有所帮助。

    That's amazing! The quality seems great by the video but how would you compare it to the cheap 0.5w hobby speakers, desktop speakers or even JBL bluetooth ones? Thank you!

    This is Great! :-)
    Could you increase the magnetic flux density over the ribbon by using a ferrous metal yolk connecting the backs of the magnets?

    也许是由旧锡罐制成的。:-)

    Thank you, there's definitely still a lot of experimenting to go. Next I want to move to bar magnets.

    凉爽,我看到亚马逊上的一些钛箔可能是试图的东西。不确定是否足够薄.03mm。

    Aluminium is a better electrical conductor and lighter the Ti. I recommend staying with Al. Going thinner than heavy duty foil does make sense though.

    谢谢你的洞察力,它有助于向前发展。我也有一个想法,我想测试代替铝箔......如果你拿起Kapton磁带然后形成一个“线圈”(如蛆),那么用另一张kapton磁带盖上线圈,基本上是一个长平面司机。

    您可以将铜胶带粘在Kapton并蚀刻到多个导体中。:-)
    您需要用带状电缆循环循环,以保持当前的相同方向
    Or!
    If you made a loop like a normal speaker coil on a long length of Kapton and made two yolks with two gaps with fields in either direction and put the top of the loop in one and the bottom in the other, they would both move sideways in-phase like your isobaric speaker!
    (我伤害了我的手腕,同时试图验证运动是否在相同的方向上,如果逆转现场和电流都是相同的。:-))

    不错的工作!
    @Tardisrepairman is right. Providing a 'Return path' for the magnetic flux by connectig the backsides of the permanent magnets will greatly improve the efficiency of your device. It'll need a bit some substance though, so I recommend multiple layers of tin can sheet metal
    Have fun with your experiments and please share the results.
