What Are Neodymium Magnet Speakers?

What Are Neodymium Magnet Speakers? Neodymium is an element with specific characteristics that make it particularly well suited for use in speaker construction. Speakers operate by using a magnetic field to generate motion in a coil and speaker cone to project an amplified sound signal. In neodymium speakers & loudspeakers, the rare-earth element is used [...]

Small Neodymium Magnets in Smartphones

Small Neodymium Magnets in Smartphones Neodymium (NdFeB) magnets are an invisible part of every smart phone. These tiny magnets are critical to the function of the phone, working quietly behind the scenes inside the phone case. These internal magnets are typically used in the speaker, receiver, vibration mode motor, taptic feedback motor, and camera auto-focus [...]

What is Speaker Magnet?

What is Speaker Magnet? The neodymium speaker magnet produces a magnetic field, and the speaker’s voice coil motor is placed in the magnetic field. When the voice coil passes through the audio current, the current will be acted by the magnetic field, which causes the voice coil to vibrate, and drives the paper basin that [...]

Neodymium Magnets vs Ferrite Magnets

Neodymium Magnets vs Ferrite Magnets Neodymium vs Ferrite Magnets - A central question that comes up in a magnet trade study is how to decide whether to use a Neodymium magnet or a Ferrite magnet for a particular application. A trade study that seems very simple at first glance can quickly become more complex once [...]

Samarium Cobalt vs Neodymium Magnets

Samarium Cobalt vs Neodymium Magnets Samarium Cobalt magnets and Neodymium Iron Boron magnets are important Rare Earth Magnets. Many people want to understand how to use them, so we wrote this guide. Here we break down the important similarities and differences so you can quickly decide which is right for your application. Samarium Cobalt [...]

Voice Coil Motors (VCM)

Voice Coil Motors (VCM), also called Voice Coil Actuators (VCA), is an electric motor consists of a magnet and yoke in conjunction with a coil. The magnet’s position, the type of magnet, the surrounding structure, etc., can influence the efficiency of the unit. Voice-Coil-Motors Some examples of applications of VCM Shaker/Vibrator Voice coil [...]

Application Classification of Rare Earth Permanent Magnet

Rare Earth Permanent Magnet Application Classification based on Operation Principle Rare earth permanent magnet can be classified into five types according to its operational principle, includes Lorentz Force Effect, Ampere’s Circuital Law, Faraday’s Law of Electromagnetic Induction, Coulomb’s Law for Magnetism and other magnetic effects. Actually, each operational principle has extremely widespread application area. Lorentz Force [...]

What you choose magnetic disc type?

Which type of magnetic disc should you choose? magnetic disc type - The basic magnetic disc is the most universal in terms of use compared with the other magnetic discs. It is the best type to be used as the magnetic component in a range of different items such as machinery, or even the back [...]

Magnet Applications

Magnet Applications, magnets for Speaker, Motor, Toy, Sensor, Switch Speaker magnets are important components in speakers Majority of speaker magnets are made from ferrites, the cost is 10 times less than NdFeB magnets. More and more speaker magnets are made from NdFeB or NdNiCo. They are processed through sintering and electroplating. NdFeB magnets for speakers are used in high-quality speakers, [...]

Speaker drivers

A speaker drivers are an individual loudspeaker transducer that converts an electrical audio signal to sound waves. While the term is sometimes used interchangeably with the term loudspeaker (speaker), it is usually applied to specialized transducers which reproduce only a portion of the audible frequency range. For high fidelity reproduction of sound, multiple loudspeakers are often [...]

Magnetically Shield Old Speaker Drivers

Magnetically Shield Old Speaker Drivers Many people don’t realize it, but speakers are actually powered by electromagnetic fields, generated by permanent magnets. Therefore, if you place extremely big or powerful speakers too close to computer hard drives, they can actually cause data loss. Speakers can also cause picture distortion on TVs or monitors, for the [...]

Salvaging Magnets from Speakers

Salvaging Magnets from Speakers This is the season to salvage junk! Where I live, poeple put out big piles of trash every year in April. It's amazing what one can find. Last year I must have found 15 or 20 speakers. I first found out about rare earth magnets from the Smash Lab episode ''High [...]

How Speakers Work

How Speakers Work - Making Sound: Speaker Magnets When the electrical current flowing through the voice coil changes direction, the coil's polar orientation reverses. This changes the magnetic forces between the voice coil and the permanent magnet, moving the coil and attached diaphragm back and forth. How Speakers Work So how does the [...]
