Does collar microphone work on the Stereo input jack given for audio input?

 

Here something about it and yes it's stereo

Introduction Ever thinking about set up a music radio station yourself? I think it would be great if you could build a music station and share your music with others. Pretty cool, right? This module could modulate your voice on the FM radio wave. And anyone who has a radio device could receive it. We build everything on this module, which makes it very easy to build a tiny radio station. We also reate library for Arduino to work with this module. We make everything easy for you.
Feature : *I2C interface 5V TTL compatible.
*Arduino plug and play.
*Onboard MIC.
*VCC Input: 3.0V ~ 5.0V .
*Connection If is very easy to connect it with Arduino if you have Arduino Sensor Shield V6. If you don't have sensor shield, you could wire them in the following way: Arduino FM Module *GND ------------ GND .
*5V ------------ VCC .
*SDA ------------ SDA .
*SCL ------------ SCL .
*Then connect the antenna. Any metal line about 75cm can serves as an antenna. Code Download the libary and upload the example sketch to Arduino. The open Serial monitor: Turn out your radio device and set it at FM 90MHz. Enjoy!
Product List : *FM Transmitter module x1.
*4pin wire x1.
*Double male recording line x1.

I'm aware of that, I soldered a condensing microphone on this Fm transmitter but when talk through the mic the output sound is very low barely hear your sound. Then i tried to amplify the sound using LM386 audio amplifier but didn't succeed yet still trying, but when i connect my phone to that Stereo input jack the sound transmitted from the transmitter is very clear and a little bit loud. Which made me wonder if a collar microphone work with Stereo input jack?

Sounds like it was better.

The LM386 audio amplifier not to good for a condensing microphone you need a preamp
