    Amplification of sound with magnets in concert equipment

    Published: 2023-05-30 16:43:28 • Daniel Gårdefelt

    Thanks to new technology, concerts and other live events have come a long way. Magnets, used to make powered concert and live event equipment, are one of the unsung stars of these advances.

    Magnets are an important part of how speakers and microphones work, which is essential for any live event. In a speaker, when an electric current flows through the coil while a magnet is nearby, it creates a magnetic field that moves the coil and emits sound. This magnetic interaction is essential to making clear, high-fidelity sound that concertgoers love.

    Magnets are also widely used when it comes to lighting. Modern LED lighting systems use magnetic drives to efficiently transform electricity into light, contributing to the mesmerizing views that give concerts more of a wow factor.

    Also, electric instruments such as keyboards and electric guitars cannot function without magnets. Electric guitars use magnetic pickups to transform the vibrations of the strings into an electrical signal, which is then amplified for the audience.

    We have written about this in more detail in this blog post.

    Although very important, magnets in concert instruments can cause problems. They must be well protected so that they do not destroy other electronic devices. The use of rare earth magnets also raises concerns about the scarcity of resources and the effect on the ecosystem.

    In the future, putting magnets together with other technological advances like AI and IoT could change concert equipment even more. Real-time performance analysis, predictive maintenance and automatic changes to sound and lighting are just some of the things that can be done.

    In conclusion, high-performance, powered music and live event equipment cannot function without magnets. They are essential to making immersive, memorable experiences for people all over the world.
