How FM Transmitters Work?
The following circuit diagram shows the cheap FM transmitters circuit and the required electrical and electronic components for this circuit is the power supply of 9V, resistor, capacitor, trimmer capacitor, inductor, mic, transmitter, and antenna. Let us consider the microphone to understand the sound signals and inside the mic, there is a presence of the capacitive sensor. It produces according to the vibration to the change of air pressure and the AC signal.
The tank circuit is derived from the LC circuit to store the energy for oscillations. The input audio signal from the mic penetrated to the base of the transistor, which modulates the LC tank circuit carrier frequency in FM format. The variable capacitor is used to change the resonant frequency for fine modification to the FM frequency band. The modulated signal from the antenna is radiated as radio waves at the FM frequency band and the antenna is nothing but copper wire of 20cm long and 24 gauge. In this circuit, the length of the antenna should be significant and here you can use the 25-27 inches long copper wire of the antenna.

Frequently Asked Questions
How do I change the frequency of my FM transmitter?
This depends on the FM transmitter with noise cancellation technology, but usually, there is a button or nob on the transmitter for you to change the frequency. You will want to make sure that your radio and the FM transmitters for iPhone and Android are on the same frequency. Some FM transmitters have an auto-scan feature to help find an unused frequency. Refer to your user manual to see how to change the frequency on your particular device.
Do you need the radio for an FM transmitter to work?
Yes, you will need a radio. The way an FM transmitter works is by transmitting through an unused FM radiofrequency. When you plug it in, the FM transmitter with a smart USB port broadcasts over an unused FM frequency so you can play on from your Bluetooth enabled mobile device on that frequency.
What is the least used FM frequency?
The lowest and least-used FM frequency is 87.8. However, most car radios can’t go lower than 88.1. If you are looking for an unused FM frequency, most unused frequencies can be found in the low or high end of the FM range of your radio. These tend to be the best FM frequencies to use with your FM transmitter with a smart USB port.
Why is my FM transmitter with a smart USB port static?
If the audio you feed into your FM transmitters for iPhone and Android is too low, you’ll hear a lot of static because there is always some static in the background, and you have to turn the sound up a TON to get your music feed. But, if the audio is too high it will “clip” which also causes distortion and static.
What station is best for cheap FM transmitters?
FM transmitter with noise cancellation technology work like tiny radios, broadcasting audio from your iPhone or mobile music player over a standard FM frequency that you tune in on your car stereo. Set the FM transmitter with a smart USB port to broadcast on 89.9 FM, tune your radio to that frequency, and you should hear your music.
Why does my FM transmitter with noise cancellation technology play quieter than the regular radio?
As you may know, in an FM transmitter with a smart USB port radio broadcast, loudness is given by frequency deviation around the central frequency. Therefore, in theory, if two FM transmitters with noise cancellation technology broadcast the same signal using the same deviation, their listeners will get the same loudness.
Now you know all the information to consider before proceeding with the purchase. Remember not to be immediately conquered by any very cheap prices, but always to evaluate the technical characteristics of each model and its compatibility with your needs. At the same time, a very expensive model could be such only because it contains accessories and features that you would actually end up not taking advantage of.
