That's called a speaker.
A loudspeaker
No, a violin does not transform electrical energy into sound energy. Instead, sound is produced on a violin by the vibrations of the strings when they are bowed or plucked. The sound waves are then amplified and projected by the body of the violin.
A radio receiver transforms electrical energy to acoustic energy
An electric drill transforms electrical energy (from a power source) into mechanical energy (for drilling). Other examples of devices that transform energy include a stove (electrical to heat energy) and a radio (electrical to sound energy).
It transforms by the air so it get to our ears. I hope this helps!
An alarm clock transforms electrical energy into mechanical energy to activate the ringing mechanism. Typically, the electrical energy powers a motor that sets the clock hands and triggers the alarm sound at the designated time.
No, a violin does not transform electrical energy into sound energy. A violin produces sound when the strings are vibrated by the bow or plucked by the fingers, creating acoustic sound waves that we hear.
The main energy-changes are as follows: Chemical (in the battery) to electrical Electrical to sound
An alarm clock converts electrical energy into mechanical energy to move the hands or display the time. It also transforms electrical energy into sound energy to produce the alarm noise.

A pop group's microphone transforms sound energy (vocal vibrations) into electrical energy (audio signals) which is then amplified and broadcasted through speakers as sound waves.
Electrical energy is transformed into electromagnetic waves, which travel through the air to a receiver in the radio. The receiver then transforms these waves back into electrical signals, which drive the speakers to produce sound waves that we hear as music or speech.
