What Kind Of Magnets Are Used In Headphone?

What Kind Of Magnets Are Used In Headphone? High-quality dynamic headphones nearly all utilize rare earth Neodymium magnets. Neodymium magnets are the strongest kind of permanent magnet available. They were invented in the 1980s and have since become standard in high-quality audio transducers (speakers, microphones and, of course, headphones). Neodymium magnets are made from an [...]

Why & How Do Use Magnets in Headphones?

Why & How Do Use Magnets in Headphones? Magnetic materials and magnetic fields are all around us but it may come as a surprise to you that the headphones you’re wearing have magnets, too! Why & How Do Headphones Use Magnets? Headphones act as transducers of energy, converting electrical energy (audio signal) into mechanical wave [...]

Why Do Speakers Have Magnets?

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 [...]

Types of Speaker Magnets

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

Where to Find Neodymium Magnets in Household Items Its a common question – where to find neodymium magnets in household items?

To put their strength into perspective, they can produce magnetic fields with up [...]

How Strong are Speaker Magnets

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 [...]

Neodymium Speaker Magnets Explained

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 [...]

Basic Composition and Microstructure of Sintered NdFeB Magnet

Basic Composition and Microstructure of Sintered NdFeB Magnet Sintered neodymium iron boron (NdFeB) magnet or neodymium (Nd) magnet, as its name implies, contains essential rare earth Nd element. Nd atoms, coupling with ferromagnetic element iron (Fe) atoms, help the magnet obtain high remanence (Br) and maximum energy product ((BH)max), which makes it extraordinary compared with [...]

Progress in Recycling of Sintered NdFeB Magnet Wastes

Progress in Recycling of Sintered NdFeB Magnet Wastes Significant efforts have been put into the recycling of bulk sintered NdFeB magnet wastes around the world in the past decade because bulk Nd–Fe–B sintered magnet wastes are valuable secondary rare-earth resources. There are two major facts behind the efforts. First, the waste magnets contain total rare-earth [...]

IEC Standard Rare earth-iron-boron (REFeB) Magnets

IEC Standard Rare earth-iron-boron (REFeB) Magnets The International Electrotechnical Commission (IEC) published the standard IEC 60404-8-1:2015 for magnetically hard materials (permanent magnets). In this standard, the part of Rare earth-iron-boron (REFeB) magnets’ magnetic properties and densities is shown in the table below. IEC Standard Rare earth-iron-boron (REFeB) Magnets In the REFeB magnets, the [...]

Recycling of Additively Printed Rare-earth Bonded Magnets

Recycling of Additively Printed Rare-earth Bonded Magnets In this work, we describe an efficient and environmentally benign method of recycling of additive printed Nd−Fe−B polymer bonded magnets. Rapid pulverization of bonded magnets into composite powder containing Nd-Fe-B particles and polymer binder was achieved by milling at cryogenic temperatures. The recycled bonded magnets fabricated by warm [...]

Recycling Of NdFeB Magnets For Rare Earth Elements (REE) Recovery

Recycling Of NdFeB Magnets For Rare Earth Elements (REE) Recovery ABSTRACT NdFeB magnets currently dominate the magnet market due to their superior magnetic properties with maximum volume minimization. NdFeB magnets are composed of 25-35 wt. % rare earth elements (REE) along with ca. 1 wt. % B and the rest being transition metals (mainly Fe). [...]

Introduction About Speaker Magnets

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 [...]

Temperature Coefficients (α and β) of Permanent Magnets

What are Temperature Coefficients (α and β) of Permanent Magnets? A permanent magnet’s magnetic properties change as a variation of temperature. For a permanent magnet, remanence (Br) and intrinsic coercivity (Hcj or Hci) are two major parameters, it is important to consider their changes with corresponding temperature variation at work. In order to describe the [...]
