Do-it-yourself headphone cases
Surely every house has a box with any outdated or broken headset from a variety of gadgets. Among this rubbish there will surely be old or non-working vacuum headphones that can be given a second life and a completely different look. Namely: headphones in the form of cartridges! It is unlikely that such will be found among any of your friends and acquaintances, which, undoubtedly, will cause interest and surprise.
To make them, we need:
- Sanding machine.
- Two dowels (one is normal, the other is with a sawn edge).
- Fine-grained sandpaper.
- Instant glue or composite “cold welding”.
- Soldering iron (with tin and flux).
- A stationery knife.
- Old headphones.
- Two spent cartridges (7.62 × 39).
Production of original headphones from sleeves
To get started, let's prepare the headphones. With the help of scissors, we separate the headphones themselves from the wires.Under the root? Then, with the help of a stationery knife, we disassemble the earpiece itself.
Be careful not to damage the speaker! Unsolder (or cut off!) From the speaker wiring. If the headphones have a damaged plug (this is, in most cases, the cause of the headphone failure), then you will have to purchase a new one in the store. You can, of course, fix the old one, but it will have a not very impressive appearance. The plug is the most common and finding it is not difficult. Next, you need to solder the plug to the cable, just by looking at the location of the colored wires on the old disassembled plug. We set aside for a while the disassembled headphones and the cable with the plug to the side in order to tackle the new headphones themselves. To do this, take our prepared sleeves and cut off the bottom part (with a cap) 10 mm long from each of them.
It’s like this:
Now we need a drill. We drill a small layer of metal in the bottom of the sleeve (there is a recess, so the core is not necessary),so that it was possible to knock out a protrusion along with a brass cap with a sharp dowel:
Next, we take the cap itself and align the dent on the metal surface, briskly left when fired. To do this, we insert a dowel into it with a cut-off edge and light blows of a hammer on the head of the dowel. We fix a dent:
Then, from the outside, we polish the bottom of the capsule with fine-grained emery paper, thereby removing the remaining bumps:
We insert the leveled capsule back into the sleeve, having driven it there with a wooden mallet. Then grind it all on felt with a goy paste to make the capsule glisten.You can, for loyalty, drop a drop of glue from the inside. This is the result of such a procurement:
Now we drill a hole in the workpiece for a wire with a diameter of 2 mm. As close as possible to the bottom of the cartridge case:
We pass the headphone cable into the side opening of the sleeve from the outside. But before that it would be nice to roll the edge of the hole with some larger drill, so that the cable does not cut about sharp edges and do not forget to tie a knot at the end of the cable so that in the future it's not accidental to tear the cable out of the earpiece. Then, using a soldering iron, tin and flux, solder the wiring from the cable to the earpiece speaker contacts:
We are waiting for it to cool down. It remains only to glue the plastic part of the earpiece, with the speaker inside, to the sleeve. Personally, I used the usual second glue for this and quite satisfied with it, but if it does not inspire confidence, you can use composite glue, such as "cold welding". So, half the work is done! Now we repeat all the above procedure with the second sleeve and earphone.At the end of the work, wipe the headphones with alcohol and put rubber nozzles - ear pads on them. Everything. Headphones are ready to use. Use on health!
