A doorbell typically uses electrical energy to operate. This energy powers the doorbell's components, such as the chime and the button, to produce the sound when the button is pressed.
A bell typically uses mechanical energy that is produced by striking or vibrating the bell itself. The sound produced by the bell is a result of this mechanical energy being converted into sound waves.
Two common devices that use electromagnets are electric motors and loudspeakers. Electric motors use electromagnets to generate movement by converting electrical energy into kinetic energy, while loudspeakers use electromagnets to convert electrical signals into sound waves.
When a bell is rung, mechanical energy from the person ringing the bell is transferred to the bell causing it to vibrate. The vibration of the bell produces sound energy as it moves through the air, creating the ringing sound. So, the energy transformations involved are from mechanical energy to sound energy.
The energy consumption of a plug-in doorbell is typically minimal, often less than 1 watt. If it is left plugged in and running continuously for 24 hours, it would use less than 0.024 kilowatt-hours per day, which is a very small amount.
The form of energy in a church bell is primarily mechanical energy. When the bell is struck or rung, potential energy is converted into kinetic energy, causing the bell to vibrate and produce sound waves. This mechanical energy is then transferred to the surrounding air as sound energy, creating the ringing sound that we hear.

It uses electricity to produce its sound
That's what the front door is for; for visitors. No 'decision' for permission is required. Your door-bell and your knocker is the invitation; even for strangers. Even if there's neither a door-bell or a knocker, anyone can come to your front door and knock. Even the police can come to your door, and have to knock or ring the bell to present you with a search warrant; or with a summons.
Umm let me think. NO!
it is like a door bell

The best type of weather seal to use for the bottom of a door to prevent drafts and improve energy efficiency is a door sweep.
