A personal cheap FM transmitter is a low-power FM radio transmitter that broadcasts a signal from a portable audio device (such as an MP3 player) to a standard FM radio. Most of these cheap FM transmitters plug into the device’s headphone jack and then broadcast the signal over an FM broadcast band frequency so that it can be picked up by any nearby radio. This allows portable audio devices to make use of the louder or better sound quality of a home audio system or car stereo without requiring a wired connection. They are often used in cars but may also be in fixed locations such as broadcasting from a computer sound card throughout a building.

How FM Transmitters Work?

Cheap FM Transmitters: Best Review & Buyer's Guide 6

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 formation of the oscillating tank circuit can be done through the transistor of 2N3904 by using the inductor and variable capacitor. The transistor used in this circuit is an NPN transistor used for general purpose amplification. If the current is passed at the inductor L1 and variable capacitor then the tank circuit will oscillate at the resonant carrier frequency of the FM modulation. The negative feedback will be the capacitor C2 to the oscillating tank circuit. To generate the radio frequency carrier waves the cheap FM transmitters circuit requires an oscillator.

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.

Size & dimension of iPhone FM transmitter
The first factor to assess is the size. Some models are obviously larger and bulkier than others. So we advise against those who are instead looking for greater practicality, you will definitely prefer a more compact radio FM transmitter with a smart USB port.
Number of frequencies of iPhone FM transmitter
To use an FM transmitter with noise cancellation technology, you must find an FM frequency not used by the radio. It is important to check that the product offers frequencies between 88 and 108 Mhz to be sure that you can take advantage of the functionality of the device.
Audio quality of iPhone FM transmitter
We are looking for a clear and interference-free sound. To obtain impeccable quality, you must adopt a Bluetooth type of product. Note that the ideal place for the transmitter is between the two front seats if the antenna of your car is at the front of the vehicle.
Hands-free
On the market, you can also find devices with a hands-free kit function. The driver can press a button on the iPhone FM transmitter t to answer a call and speak to his interlocutor safely. However, if you are particularly interested in the presence of a microphone, you will have to carefully choose a device that includes a well-made one.
Price and warranty of iPhone FM transmitter
Very important elements to take into account concern the price and the guarantee of the product. The prices can vary between 15 and 30 dollars, it all depends on the functionality and the brand of manufacture. Obviously, remember to check the product warranty in case of concern later.
Display functionality
The basic models are limited to standard information, such as the frequency and status of the battery. Someone else also adds the indication of the volume, the AUX source (USB or SD card) from which the music comes, even the details of the song being listened to, and any incoming calls if connected to a smartphone!
These more detailed models are obviously priced higher. It should also be considered that if you plan to use your FM transmitter with a smart USB port while you are in the car, you will have little time to read all this information with each new song being played. So make sure you buy a model that has enough large display that required your needs.
Performance of iPhone FM transmitter
Performance is definitely last but not least. They depend on various external factors such as the quality of your car radio or the audio system of your car. This is obviously a risk to be taken into greater consideration if you live or drive in very crowded cities.

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.

Conclusion:

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.
