External earphone of digital camera

It should be an interface without microphone input.

If you are interested, you can install your own microphone jack.

Did you assemble your own radio at school? It's much simpler than installing a radio.

In Beijing, you can buy a 3.5mm socket at Zhongfa Electronic Market in Huang Zhuang, Haidian.

Turn on your camera, find a place near the existing microphone where you can install this socket, make a hole and install the socket. The above is the reverse operation of the machine.

Then, unplug the existing microphone and connect it to this socket of yours. Ordinary microphones have no polarity, so don't worry about connecting them backwards. If you don't trust me, it's better to connect by polarity. It should be considered that the host microphone does not work after the external microphone is inserted in the wiring process. 3.5mm socket has this function. These are electronic operations.

The above expenses will not exceed five yuan. Of course, if you don't have an electric soldering iron, you can buy it at Zhongfa, and there are welding wires.

Wish you success!
