Sound energy is produced when an object vibrates which results in noise and magnetic energy is an energy form of moving electrons. A transducer is a machine it transforms sound energy into magnetic energy.
Sound shudder can obtain electrical energy hyper the principle of electromagnetic induction which produce a moving charge utilizing a magnetic field and a conductor including a wire coil advancing to one another producing magnetic energy.
This post gives you a detailed explanation of how sound energy is converted to magnetic energy and also the sound energy to magnetic energy examples.
How to convert sound energy into magnetic energy?
Consider a moving coil microphone is an instrument that can convert sound energy to magnetic energy continuously employing waves the voice coil is an important part of a moving coil microphone and it is a coil of very thin insulated wire and this coil vibrate freely in between the poles of the magnet this coil is connected to diaphragm.
The diaphragm vibrates when sound is induced in the voice coil these signals are strengthened by using an amplifier and sending you a loudspeaker the important parts of a loudspeaker are the permanence magnet voice coil and diaphragm.
The voice coil is placed between the opposite poles of the permanent magnet a diaphragm is attached to the coil the electrical signal corresponding to the variations of sound energy from the microphone is amplified by an amplifier and is fed to the voice coil which is placed in the magnetic field vibrates Following the intensity of electrical signal-producing magnetic energy.

Microphone
The microphone is a loudspeaker and it is the fundamental block of communication, sound waves hit a diaphragm producing sound energy which causes it to move this diaphragm is attached to a coil surrounded by a magnet which creates a magnetic field around the coil and the coil movement producing magnetic energy then creates an electrical current.
Transducers
Automatic doors consist of infrared radiation which vibrates the door producing sound energy and then emitting infrared rays reflected by a person proceeding towards the door converting into magnetic energy then received by a device that transforms to electrical energy and then opens the door.
Speakers
Speaker consists of a voice coil and magnet speaker motor producing the vibrations which are sound energy when electricity flows through the copper windings it naturally generates a surrounding magnetic field which is nothing but magnetic energy.
Traffic signal mike
In signals, there is the number of vehicles that makes traffic produces sound energy which will be detected and sensed by mike and convert into magnetic energy to produce electrical signals.
Robotic technology
In signals, there is the number of vehicles that makes traffic produces sound energy which will be detected and sensed by mike and convert into magnetic energy to produce electrical signals.
Radio
Radio has a radio frequency signal which is an alternative to a sound signal which performs the modulation so sound energy is converted to magnetic energy and then transform to electrical energy.
D size battery
Secure the rubber band around the d size battery and take a nail rounded with insulated wire and is connected to the negative terminal of the battery then there is a vibration which is sound energy generates electricity iron nail act as a magnet producing magnetic energy.
Prototype technology
The Source of sound energy is given to the magnetic diaphragm and the function of this diaphragm is to convert the sound into an electrical pulse which acts as magnetic energy.
Thermo-acoustic generator
Thermo-acoustic generators steer heat into sound energy when a copper coil is rotated between magnetic poles producing a magnetic field that interfere with the conductor and converts sound to magnetic energy which operates the generator.
Machinery
In electrical machines sound energy is produced because of an automatic source and electromagnetic field changes convert to magnetic energy which grabs the metal parts.
Refrigerators
The object takes heat during the heat absorption process refrigerator evaporates by making a sound and transforms into pure vapor and a strong magnetic field is applied this magnetic energy is used in the freezer.
Magnetic microphone
Sound waves lever a corium which wreaks a rod start in a center of a magnetic field inducing electricity in the coil with the conversion of sound energy into magnetic energy.
Electric motors
When we provide the mechanical force with a windmill rotor attached to the loop it produces a sense of vibration which is sound energy and leaves the magnetic field as it is and wind rotates the blade converts to magnetic energy to produce electrical current.
Compass
When the magnet is kept near the compass to demonstrate the poles the direction of the compass needle points red part makes a sound then the direction of the magnetic field is demonstrated by converting sound sense into magnetic energy.
Hard disk drives
Hard disk drivers can hold more information than the local library it contains a high-speed spinning disk there is a recording head that records the sounds in a disk and converts them to a magnetic pattern in the form of magnetic energy.
MRI scanners
MRI scanners produce sound energy so we will probably wear earplugs during the scanning magnet in the machine creating a strong magnetic field as magnetic energy.
Maglev trains
Maglev train produces sound energy because electromagnetic force among train and track adjourn them to stimulate the inducement loop to produce magnetic field this magnetic energy jerks the train forward from front and pursue it forward from behind.
Vending machines
After inserting 30 coins of any currency the machine will serve you a drink while serving it makes some sound and converts to magnetic energy to separate the coins.
Televisions
Television consists of a receiver and transmitter and a camera and requires a complicated network and antenna picks some radio waves from the transmitter with satellite incoming signal feeds into the antenna which carrying picture and sound more than one station and electron beam passed through a ring of electromagnetics convert to magnetic energy using this energy the electrons can be steered by magnets because they have a negative electrical charge.
Microwave oven
Microwave ovens have sound energy and magnetron produce powerful microwave radiation microwaves are electromagnetic waves in a particular spectrum they have oscillating electric and magnetic fields, when food is placed the microwave causes heat in the form of sound energy then converted to magnetic energy and this magnetic energy is responsible for the cooking of the food.
Telephone systems
when we speak on our phone our voice is picked up by the phone’s microphone the microphone turns our voice which Is a sound into a digital signal with the help of a MEMS sensor and IC so to transmit these electromagnetic waves are picked up by the tower and convert them to high-frequency light pulses because of this sound energy is converted to magnetic energy.
