Hello everyone, I’ll tell you today how to make a simple, but high-quality microphone, it is suitable for recording sounds for clips, as well as for various programs such as skype, video games. This circuit contains a total of eight components.
So what do we need;
- resistors per 1ohm 3 pcs;
- disk capacitor 100-300 pF;
- electrolytic capacitor 47 uF 16 V;
- microphone;
- transistor BC547;
- plug 3, e Jack;
- any plastic case;
After we found all the components for assembling the microphone, we begin to solder everything as shown in the diagram. To get sound on two channels, you need to use two such schemes together.
Solder the plug as shown in the photo.
We assemble everything with a hinged installation so it will turn out to be more compact after assembly, we connect and check it on a simple voice recorder. If it worked for us, then we collect it further, and if sound is not recorded, then you need to check the polarity of the microphone and plug.
Do not reverse microphone polarity.
Then we put everything in the case I used a plastic tube, you can use a syringe or any other case.
I folded the circuit in half, isolating it in the middle with valentine, but I can solder it even more compactly.
On the reverse side filled with hot glue.
We check the performance with the case, I check on the phone.
