Earphone Mic Installation Modification
Generally, when I am in my workplace I use this earphone since last 8 years, as you all know when you are comfortable with the things you cannot change it frequently without reason.
Since last few days’ peoples from other side complaining that some time they couldn’t hear my voice clearly. So one day I decide to just check the unit & fix it if possible or I can use my another Bluetooth neck bend which I am uncomfortable because of frequent charging or may be go for new wired headphone.
I have already started work & missed some starting photos ……. so for inspection I opened button unit directly because this button unit is having mic inside. I seen mic is directly connected on the PCB & it is very small in the size…
Searched for the same size Mic but not find any lead, so I opened my collection of salvaged parts.
I found one mic but it is larger than the mic on the PCB …. if by chance I manage to solder it on PCB the outer casing will not fit .so I have to modify it some another way.
Soldered thin salvaged wires from non-repairable headphones to this replacement Mic.
Negative terminal is always connected to the outer body of the mic
Always check the polarity when connecting condenser mic.
Made hole in plastic top cover of the button unit & pass wires through it & soldered wires on the PCB in place of old removed mic.
After soldering the wires, I checked Mic for working in mobile it works well.
Hence fitted the mic on top cover using the white glue.
And earphone is ready for the use.
