Eclipse Magnetics designs, produces and supplies high performance magnetic assemblies for acoustic applications.
With over 100 years of experience, Eclipse Magnetics designs, produces and supplies magnets and magnetic assembly solutions to satisfy the wide ranging magnetic performance requirements and
specifications of loudspeaker, horn and microphone applications.
Whether you have a completed design and need a reliable long term supply partner, or you require design assistance and technical support, we can help with your assemblies and sub-assemblies for acoustic applications such as:
We offer a wide range of magnetic materials, making our speaker magnets suitable for use in every application and industry.
Here are some of the most common magnet materials for speakers.
Neodymium magnets are the most powerful of the Rare Earth magnets. Size for size, there is no better maximum performance magnet.
Ferrite magnets, also known as ceramic magnets, are popular in larger driver assemblies.
Alnico drivers tend to be longer in axial length to allow for higher performance and reducing demagnetising effects.
Samarium Cobalt is a weaker variety of Rare Earth magnets but gives a more consistent performance in applications which are subject to wide temperature variations.
Eclipse Magnetics designs, produces and supplies magnets and magnetic assembly solutions to meet your unique requirements. This could include efficiencies such as:
We will work with your engineers and designers to understand your requirements and provide the optimum magnetic solution for your needs.
Do you need regular stocks of speaker magnets?
We offer a stock-holding service, enabling you to place call off orders and arrange "just in time" delivery schedules to suit your business needs. This can help to reduce the amount of stock that you need to keep on site, whilst spreading your costs throughout the year.
A speaker works by converting electrical energy (the signal from your playback device) into mechanical energy (sound waves that you can hear). But how exactly does it do that?
The signal enters the back of the speaker through electrical wires. This current is then passed into a cylindrical wire coil, which is suspended between the poles of a permanent magnet. As current passes through the coil, the alternating current causes the coil to move back and forth within the magnetic field - thanks to Faraday's Law.
The coil drives the centre of the speaker cone, causing it to move back and forth along with the coil. As the speaker cone moves, it pushes and pulls the surrounding air, creating sound waves.
So, you can see the importance of magnetics within a speaker.
Yes, every speaker uses permanent magnets. This is because magnets provide the force that enables the speaker to convert electrical energy into mechanical energy - or sound waves. So, whether the speaker is within earphones, a car stereo system or a cinema sound system, it will use magnetics.
