Tiny NdFeB Magnets in Smartphones and Personal Electronics Small Tiny NdFeB 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, [...]
What Are Neodymium Speakers? Neodymium is an element with specific characteristics that make it particularly well suited for use in speakerconstruction. 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, the rare-earth element is used as the primary material [...]
Why Do Speakers Have Magnets? Speakers have magnets because magnets create an opposing magnetic field which results in vibrations which are the sounds we hear. Let’s explain a bit further. As you already know, for speakers to work, they need electric current. This current goes through a coil in the speaker and creates a magnetic [...]
Neodymium Speaker Magnets Explained In this article, you will meet a component that perhaps doesn’t get the exposure that it should – the magnet. While each speaker driver is made up of two magnets – an electromagnet and a natural/permanent magnet – the focus will primarily be on the latter. To reproduce sound through a [...]
Types of Speaker Magnets Its a common question, which type of magnet is used in speakers? If you are new to the speaker world, you have to understand that every sound speaker, whether small or the most powerful one, all are designed with a permanent magnet. The magnet provides a permanent magnetic field for the [...]
Where to Find Neodymium Magnets in Household Items Its a common question – where to find neodymium magnets in household items? Neodymium magnets are made of neodymium as their name suggests and are the most widely used type of rare-earth permanent magnet. To put their strength into perspective, they can produce magnetic fields with up [...]
Magnetic Speaker Systems Speakers have been utilising permanent magnets since 1930 and in the last 87 years the core technology has remained largely unchanged. However, with the advent of new materials and ever increasing strength of Neodymium magnets the speaker is constantly been re-invented. None more striking than the B&W Nautilus, now superseded in terms [...]
How strong are speaker magnets? Speaker magnet strength ranges from about 0.001 tesla all the way up to about 1.5 tesla (the strongest neodymium magnets). The basic function of speaker magnets is to translate an electrical signal into an audible sound. To achieve this functionality, speaker magnets don’t need to be extremely strong. So why [...]
Some Introduction About Speaker Magnets Speakers are a type of transducer which can transfer the electric signal to the acoustic signal. The sound quality of the speaker is largely depended on the speaker magnets. Speakers can be classified to internal magnetic type and external magnetic type according to the magnetic circuit structure. Speakers also can [...]
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 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 [...]

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, 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, [...]
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 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 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 - 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 [...]
Neodymium speaker magnet Neodymium speaker magnet is the latest development in this industry, it’s not as expensive as Alnico but costs a bit more than ceramic magnet speakers. It has the advantages of both weighing about 50% less than other speakers and having stronger magnetic properties. Speakers made from neodymium magnet respond to [...]
