Application of magnets in the music industry

If you work in the music industry or build musical instruments, you probably know that the performance of an instrument depends on more than just the person playing it, such as whether or not the instrument is tuned. However, you may not be aware that the magnets inside an instrument can greatly affect the acoustics and sound.

The strength and size of the magnets inside your musical instrument, and even your speakers, can affect performance. When building a musical instrument, you should consult with a magnet expert to help determine the best magnet strength and size for your application. to help you determine the best type of magnet for your application.

Electric Guitar

Powerful magnets are essential for any guitar or bass player because they affect the quality of the pickups. Without powerful magnets, electric guitars and basses would not be able to scream through a loud crowd. Inside guitar pickups are alnico magnets or ceramic bar magnets. Guitars have between 1 and 6 magnets, depending on the design. Magnets that use one or two magnets usually have a bar magnet mounted under the pickup that charges the pole piece that goes through the coil. Other guitars have magnets that are used as pole pieces; it depends on the design of the guitar.

By utilizing magnetic induction, a guitar's pickups “pick up” the vibrations of the guitar strings as they interrupt the magnetic field and convert it into an electrical signal, which is then transmitted via a cable through an amplifier.

Microphones

Magnets are also important in audio applications such as microphones. AlNiCo magnets are used in microphones because they offer a number of advantages - for example, they are highly corrosion-resistant and resistant to breakage. AlNiCo magnets generate a magnetic field when sound waves hit a diaphragm, which is connected to a coil surrounded by magnets. The coil then moves back and forth, creating an electric current throughout the magnetic field. The current flows out to an amplifier or recording device, producing amplified sound.

Speakers

Every time you listen to music through a speaker, you are using a magnet. Inside the speaker are ferrite/ceramic magnets that act as electromagnets when current is passed through the coil. The magnet creates an opposing magnetic field, which creates vibrations. The vibration is what we hear through the speaker. The larger the magnet, the larger the opposite magnetic field. In other words, the bigger the magnet, the louder the speaker.

Ceramic Ferrite Rings Commonly Used in Speakers

In addition, inside the speaker, ferromagnetic fluid magnets are used to remove heat from the voice coil. This is effective because ferromagnetic fluid is paramagnetic, which means it becomes less magnetic at higher temperatures. As a result, when the ferromagnetic fluid particles heat up, they are directed toward the heat sink. Meanwhile, the cooler ferromagnetic fluid moves closer to the voice coil.

Drums

On drums, magnets play a key role in electric and military drums. In these drums, there are “trigger pads” that sense vibrations when a hit is made. Not only does it detect that the pad has been hit, but it also registers the force of the hit based on the level of vibration. This produces a change in sound when the drum is played. Often, there are multiple areas on the pad that produce different sounds - when you hit the edge, it makes a different sound than when you hit the center. In addition, the damper/snare weight contains two magnets that form a “lock” to hold the weight in place. When used properly, the weights will optimize the sound of your drum and give you more control over the sound.
