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 [...]

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 [...]

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 [...]

Four Classes of Modern Commercialized Magnets

Four Classes of Modern Commercialized Magnets Magnets are an important part of our daily lives, serving as essential components in everything from electric motors, loudspeakers, computers, compact disc players, microwave ovens and the family car, to instrumentation, production equipment, and research. Their contribution is often overlooked because they are built into devices and are usually [...]

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 [...]

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? 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

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

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 [...]

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.

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 [...]
