我们在网上看过不少 DIY 扬声器,比如纸杯扬声器,锡箔纸喇叭等,然后感叹一声“太神奇了”,再然后,就没有然后了,因为没有具体的 DIY 过程。今天,我们来看看 DIY 便利贴扬声器的具体制作过程。

据悉,这个创意是由纽约布鲁克林先锋艺术创意中心的声学教师 David Sheinkopf 想出来的。

虽然难度不大,但是我们还是要先上上物理课,讲讲扬声器的工作原理:音频信号通过线路传送电流,在铜线圈上产生不同大小的磁场,磁场的变化带动振膜上的磁体运动,进而使得振膜发生震动,通过空气发送声波。

而我们要做的,就是形成一个有效的扬声器回路系统,用便利贴或其他薄纸来充当振膜,最终完成音频信号到声波的转换。

好,这节课到此结束。接下来是制作前的准备工作:

工具

- 砂纸

- 剪刀

材料

- 1 米长的电磁线,可以在破旧的变压器上找到,一匝匝的那种。

- 胶带

- 便利贴,其他材质的薄纸也可以。

- 音频线,坏掉的耳机里就有。

- 小型稀土磁铁

- 2 个鳄鱼夹(非必备,把线搓在一起一样能连接)

统计

时间:15 分钟

费用:4 美元(不到 30 元人民币)

难度:1 星(最高 5 颗星)

制作

1. 用砂纸打磨掉电线两端约 3cm 的绝缘外壳。

2. 将电磁线在手指缠绕出整齐的线圈,将刚刚打磨出的线头露出来,然后用胶带固定。

3. 用胶带将小磁铁粘到某个平面,比如桌面。

4. 用便利贴把磁铁覆盖。

5. 把第二步制作的线圈放到便利贴的中间位置,并用胶带固定。

6. 用鳄鱼夹将音频线的线头跟线圈连接。注意,没有鳄鱼夹的话,可以把线跟线圈接上即可,但不要拧死。

7. 将音频线的插头插入手机,然后播放音乐。如果没有听到声音,你可以对导线和磁铁的位置进行调整。
