speaker magnet.

We all know that inside the speaker horn will use magnets, some partners will remove the magnet as a child, you can find the magnet inside is black, this is a ferrite magnet, that is, universal magnet. But with the development of the market, more and more speaker equipment inside the neodymium magnet will be used to replace the traditional speaker magnet. There are three types of magnetic materials in speaker magnets: alnico magnets, ferrite magnets, and neodymium-iron-boron magnets. Each type of material has a different effect on the tonal characteristics of a loudspeaker. 1. Alnico magnets are the initial magnet material used in loudspeakers to produce classic tones. These speakers sound warmer and sweeter at lower volumes, and many musicians find them more responsive to a player's touch. The disadvantages are low power, narrow frequency range, hard and brittle, and very awkward to work with. In addition, cobalt is a scarce resource and Alnico is relatively expensive. From the comprehensive cost-effective, speaker magnets using Alnico is relatively small. 2. Ferrite magnets are developed as a cheap alternative to Alnico. Ferrite magnets are generally made into external magnetic horn. The ferrite material has very low magnetic force and has to have a certain volume size to achieve the driving force of the horn. Therefore, it is usually used in louder audio speakers. The advantage of ferrite is that it is cheap and cost-effective; the disadvantages are large size, low power and narrow frequency range. 3. The last material is neodymium iron boron magnet So what are the advantages and disadvantages of neodymium iron boron speaker magnets? Advantages: high magnetic performance, small size, the weight will be lighter than other speakers, wide frequency range. Excellent sound quality, good elasticity, good detail, good voice quality and accurate sound field positioning. In terms of price, they are between Alnico and Ferrite magnet speakers. Mostly used in high end speakers. Disadvantages: disadvantages are sintered moulding, expensive, magnetic, easy to oxidise, slightly less bass, and high temperatures can cause irreversible magnetic degradation
