Speaker Magnets Ceramic Vs Neodymium

Each material of course has different magnetic properties and cost.

Speaker magnets ceramic vs neodymium. In the past two years are producers who have won several international awards some even innovation awards with speakers that use ferrite magnets. 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. Ceramic and neodymium magnets have different drawbacks as well.

Due to their relatively high price and sensitivity to external conditions neodymium magnets are best only for applications where extremely high magnetic fields are needed such as powerful turbines and generators and particle physics experiments. Mixtures of ceramic materials were poured into molds to form these inexpensive yet effective magnet. Neodymium seems to be the wave of the future especially with reduced weight and overall costs coming down. My experience with neo speakers is that they sound good and weigh less with very high power watts capability compared to ceramic speakers and usually well beyond the range of alnico speakers in the same price class.

On the other side of the fence is neodymium magnets which is one of the two different types of rare earth magnets. Ceramic and neodymium magnets are each most appropriate for different applications. The biggest differences between neodymium and ferrite magnets. That is to say that a smaller neodymium magnet can produce a given amount of attractive force than would be needed with a ferrite magnet.

They cannot be used in machinery that experiences a lot of stress or flexing. That means that any speaker or headphone that uses neodymium will. They become demagnetized if they are exposed to high temperatures above 480 degrees fahrenheit they have only a moderate magnetic strength. Originally developed in the.

I dislike generalizations about speaker magnet types. It produces the most magnetic flux per ounce making it ideal for use in multiple speaker cabinets to maintain performance while reducing handling and shipping weight. Ceramic magnets are extremely brittle and easily broken. Neodymium speaker magnets explained.

In addition to ceramic magnets were also made of strontium and barium ferrite. Why the manufacturers of speakers loudspeakers have not switched to production of speaker with neodymium magnets especially those for low freq. There seems to have been a quite a debate in the audio industry about the usage of ferrite magnets vs neodymium magnets in audio speakers. It is true that neodymium magnets have a greater magnetic force to size ratio.
