Aroma lamps, or diffusers, are used to diffuse essential oils. They may project the oil into the air by heating it, letting it evaporate naturally, or nebulizing it using compressed air or ultrasonics.
A heat diffuser contains a small candle under a bowl to vaporize a mixture of water and oil. This device is very cheap and doesn't need a special maintenance, however, the heat can change the chemical structure of the oils.

Evaporative diffuser
An evaporative diffuser is a device that uses a pad, filter, or reeds to diffuse the essential oils. One of the disadvantages of this tool is that the light elements of the essential oils will be circulated around the ceiling first and will only come down at the end of the process.Heat diffuser

is a device that does not use water or heat as other diffusers. The bottle of essential oil is attached directly to the nebulizer. As a result, the unit uses 100% pure essential oil. The benefit of using this device is a strong concentration of the essential oil. However, it can be noisier than the other devices depending on the specific model in use.
Ultrasonic diffuser
An ultrasonic diffuser is the same as a nebulizer but uses a water/oil mixture. This makes the mist not so concentrated. This device can be used as a humidifier. These diffusers contain anultrasonic transducer
Ultrasonic transducers and ultrasonic sensors are devices that generate or sense ultrasound energy. They can be divided into three broad categories: transmitters, receivers and transceivers. Transmitters convert signal (electrical engineering), ...

Cavitation in fluid mechanics and engineering normally is the phenomenon in which the static pressure of a liquid reduces to below the liquid's vapor pressure, leading to the formation of small vapor-filled cavities in the liquid. When sub ...
