Our customer had a problem with metal dust in his smartphone speakers and he decided to rescue his smarthphone with magnets.
Because a broken smartphone is always annoying.
I work in a metal processing company. I regularly have metal dust and shavings at work and inevitably in my trouser pockets.
After a short time, the magnetic metal particles clog the speaker openings on my cell phone.
As a result, the function was restricted, as you could almost no longer hear the conversation partner.
As a simple weapon against the magnetic effects of the loudspeakers, I thought of a stronger magnetic field than the loudspeakers have. So I just ran a small block magnet over the openings. The magnet collects most of it. To loosen stuck metal dust, I pick a few small magnets on a needle to magnetize them. You can then carefully loosen the dust with the tip and collect it.
Smartphone rescue with magnets
This is a very practical magnet application. It saves you in the worst case not only the trouble and nerves but also a lot of money for the repair!
We thank our customer for sharing his idea with us and all of you – Thank you!
