A Short Summary of Planar Magnetic Drivers
You may have noticed that many excellent planar magnetic driver earphones have emerged recently. Is 2022 the year of Planar IEMs? Are you interested in knowing more about planar magnetic drivers and their mechanism?
Without wasting more time, let's get started and dive right into this short introduction of planar magnetic drivers.
Origin of planar magnetic drivers:
Planar magnetic drivers became more widely recognised after planar magnetic headphones got increasingly popular. The planar magnetic technology was first developed for NASA purposes, and later used in the headphone industry.
Mechanism of planar magnetic drivers:
Planar magnetic headphones produce sounds by regulating the electrical flow through a film that has been suspended between magnets with equal magnetic force. The magnets are placed on either side of the electrically-active diaphragm material. Upon the application of current, this diaphragm gets electrically charged, creating a magnetic field. When the magnets on either side of the diaphragm react with this magnetic field, it causes the diaphragm to move, therefore creating sound waves. Thanks to the isodynamic field, these movements are constant, uninterrupted, and equally distributed across the whole diaphragm, which ensures perfectly balanced sound reproduction.
Advantages and disadvantages of planar magnetic drivers:
Every coin has two sides, just like every item has its pros and cons. While planar magnetic drivers are highly in demand for their excellent sound quality and durability, they are usually heavy and large, and also difficult to drive. Therefore, it poses a unique challenge for audio engineers to create fine planar products with ergonomic design.
Now that you have a better understanding of planar magnetic drivers, here are some suggestions for Planar IEMs and headphones that are available in our store!
