In modern times, electrical energy is harvested and is nearly always converted to some other type of energy (heat, motion, light, etc.). It is supplied by electric current and electric potential (voltage) and is delivered through electrical circuitry. What is electrical energy? “Electrical energy” is defined as electric potential energy. When I say “inaudible,” I specifically mean inaudible to humans. Inaudible infrasound happens below 20 Hz, while inaudible ultrasound happens above 20,000 Hz. The strength of a sound wave is generally measured in sound pressure level (dB SPL) or Pascals (Pa).Īudible sound waves happen in the frequency range of 20 Hz – 20,000 Hz. The oscillations of the particle disturbances caused by sound waves are defined within the range of 20 Hz and 20,000 Hz. What is a sound wave? A sound wave is a type of mechanical wave defined by the pattern of disturbance of particles within an elastic medium. Mechanical waves (and, therefore, mechanical wave energy) can only be transferred in media which possess elasticity and inertia (gas, liquid, solid). What is mechanical wave energy? Mechanical wave energy is the energy carried by a mechanical wave (an oscillation of matter within a medium). As the diaphragm moves according to the varying sound pressure levels, the microphone produces a coinciding mic signal.īefore we get deep into the mechanics of how a microphone converts energy, let's further define the energies in question. More simply put, microphones convert sound waves into audio signals.Ī Picture Describing The Microphone As A TransducerĪ microphone's diaphragm reacts to the sound waves it is subjected to. Microphones work as transducers, converting mechanical wave energy into electrical energy. What is a transducer? A transducer is a device that converts one form of energy into a different form of energy.

The microphone diaphragm vibrates as it's subjected to sound waves and creates a coinciding audio signal via electromagnetic or electrostatic principles that will be outputted. How do microphones work? Microphones work as transducers, converting sound waves (mechanical wave energy) into audio signals (electrical energy). Microphones are part of our day-to-day lives and are somewhat taken for granted, so I'm glad you asked about how they function! It's not often that we think about how microphones work.
