How to Make a DIY Microphone Using an Old Speaker
Basic in any studio, most low-recurrence microphones cost somewhere in the range of $100 to $500. The ones on the lower end of the value scale don't convey spectacular quality; they permit a decent arrangement of seep from treble instruments while giving bass reaction just somewhat superior to a standard vocal mic would. Luckily, utilizing a couple of extra parts, you can construct one that adversaries the costly models.
This is one of the most straightforward studio hacks, reasonable for apprentices with no hardware experience, and the outcomes are really astonishing. Even better, you'll spare many dollars while upcycling stuff you weren't utilizing. The main devices required are a power drill-driver and something to strip wires (a lineman's plier or most pocket multitools will do it). Here's the formula.
1. Expel the woofer from an old speaker
Most speakers can be figured out into DIY mics. The most valuable are the woofers (bass speakers) from three-way speaker towers. Current speakers will in general be littler, so these large towers are as often as possible sold efficiently at flea markets or put out by the road for nothing. You may well as of now have some you're not utilizing. Go for an enormous woofer; 12 inches or so is good.Remove the speaker barbecue, in the event that it has one, and unscrew the four fastens that hold the woofer the bureau. When you have the cone of the speaker out, you'll see two wires, no doubt red and dark, appended to the cone. Cut these wires where they append to the inside of the speaker box, leaving however much slack joined to the cone as could be expected. Presently, strip about an a large portion of an inch of plastic protection off the cut parts of the bargains, being mindful so as not to cut the metal strings inside. You currently have the mammoth stomach of your low-recurrence microphone. Try not to discard the screws you just took out; you'll need them later.
Evacuate the speaker flame broil, on the off chance that it has one, and unscrew the four tightens that hold the woofer the bureau. When you have the cone of the speaker out, you'll see two wires, in all probability red and dark, joined to the cone. Cut these wires where they join to the inside of the speaker box, leaving however much slack appended to the cone as could be expected. Presently, strip about an a large portion of an inch of plastic protection off the cut parts of the bargains, being mindful so as not to cut the metal strings inside.
You presently have the mammoth stomach of your low-recurrence microphone. Try not to discard the screws you just took out; you'll need them later.
2. Join the speaker to a microphone link
Expel the screw from the female finish of a microphone link. The metal lodging slides off, uncovering three patched terminals. Of the wires appended to these terminals, one wire will regularly be white and another dark (the dim one is a ground wire, which we won't require). Utilizing your pincers, cautiously expel the wires from the terminals. As in the past, take a little protection from the high contrast wires.
Presently you're prepared to join the wires. Contort the dark wire from the speaker to the dark wire on the link. At that point join the red speaker wire to the white wire from the link. When they're bent together, you'll need to screw a plastic wire nut onto the joined wires to keep them together and keep them from establishing out on some other metal. In the event that you don't have any wire nuts helpful, simply envelop the joints by a short length of electrical tape.
3. Test your microphone
Before doing any more work, plug your mic into a ghost controlled blending board and test it. Have a go at holding it up before a bass drum, low register guitar, or any instrument with a great deal of low end. In case you're getting a decent sign with no buzz or static, you've done the initial two stages accurately. Presently seal up those wire associations with more tape so they're secure. It's an ideal opportunity to complete the activity.

4. Assemble a casing or box so your mic can hold up
Clearly, you can't continue holding your new mic up before sound sources. Discover some piece wood and utilize the speaker's mounting screws to build a straightforward casing that permits the mic to hold up. It shouldn't be pretty, however it needs to be secure and solid. You can get inventive with this progression and utilize whatever may work.
When working, be incredibly mindful so as not to cut the cone of the speaker with your instruments! Screw it together immovably, utilizing more equipment than you might suspect you'll require. It generally pays to overbuild. On the off chance that a bandmate can sit or step on this structure without breaking it, you've carried out your responsibility. As another option, in case you're talented with a roundabout saw, you can simply remove the part of the first speaker bureau that had your woofer mounted in it initially, boring an opening in the container for the microphone link to go through.
5. Record with your new, free microphone
Other than being modest and effectively developed, this mic has three intense preferences over locally acquired mics. To start with, the tremendous measurement of the stomach concedes huge amounts of low-recurrence reaction. Second, this mic "hears" no treble, so even on a drum set there will be a ludicrously limited quantity of seep from the catch and cymbals. Ultimately, the mic's normal information gain is low. It takes a ton of pneumatic stress to move that enormous stomach, so you can put it a large portion of an inch from a roaring bass drum or speaker bureau without cutting.
The one drawback? The speaker cone is delicate, so it's a smart thought to store it some place up high or in a bureau when it's not being utilized. It would be a disgrace to have somebody kick the cone accidentally and wreck your difficult work.
