Electrical energy to sound energy
Example
Speaker
A coil of wire(voice coil) is placed (inside the cone) in magnetic field produced by a strong permanent magnet, the signal to converted is applied to the coil, so a magntic field is produced due to electric current in the coil. The coil system and permanent magnetic field interacts, so mechanical motion is produced and it causes the coil to move to&fro and it touches the cone, therby reproducing sound from the electrical signal..
does electrical energy can change into sound? yes it can
Electrical - mechanical - sound. From electrical energy, electricity is passed unto an amplifier, a microphone or a cdplayer is connected to the amplifier. The amplifier then change the sound entering it into mechanical energy. Then sound is passed out through a speaker cable givin sound energy
With a microphone
A loudspeaker changes electrical energy into sound energy by converting the electrical signal into vibrations that move the speaker cone and produce sound waves.
A microphone is a device that converts sound energy into electrical energy. Sound waves cause a diaphragm in the microphone to vibrate, which in turn generates an electrical signal that represents the sound.
Electrical energy -> Sound energy.
Electrical energy -> Heat energy -> Sound energy.
solar cells change radiation energy energy into electrical energy solar cells change radiation energy energy into electrical energy solar cells change radiation energy energy into electrical energy
SOUND
The energy change in an electric buzzer involves converting electrical energy to sound energy by causing a diaphragm or other vibrating element to produce sound waves, creating the buzzing sound. This process involves a transformation of energy from electrical to mechanical and acoustic forms.
Sound energy can be converted to electrical energy using a device called a microphone. The microphone converts the sound waves into electrical signals by detecting the vibrations caused by the sound waves and converting them into a voltage signal. This electrical signal can then be processed and used to power various electronic devices or stored for later use.
The speaker on the phone converts electrical energy into sound energy, which generates the audio you hear during the phone call.
