Speaker magnets refer to the magnet used in the horn, that is, the magnet used in the horn.

Several factors should be considered when selecting speaker magnet

  • First of all, it is necessary to determine the ambient temperature in which the horn works, and which magnet should be selected according to the temperature. Different magnets have different temperature resistance characteristics and can support different maximum operating temperature. When the working environment temperature of the magnet exceeds the maximum working temperature, magnetic attenuation and demagnetization may occur, which will directly affect the sound production effect of the horn.
  • Secondly, the horn magnet should be selected by considering the magnetic flux demand and the magnet volume. The louder the speaker is, the better the sound is? In fact, the bigger the magnet, the better. From the influence of the magnet performance on the sound output quality of the loudspeaker, we can find that the magnetic flux of the magnet has a great influence on the sound quality of the horn. Under the same volume, the magnet performance is: NdFeB > alnico > ferrite; under the same magnetic flux requirement, the volume of NdFeB magnet is the smallest and the ferrite is the largest. For the same magnetic material (the same material and same performance), the larger the diameter and the greater the magnetic induction, the greater the power of the horn is, the higher the sensitivity of the horn is, and the better the transient response is. Therefore, it is necessary to determine which kind of magnetic material to choose by considering the limitation of horn volume to magnet volume and the requirements of magnetic flux performance.

Add: some people ask how many cores and how much magnetism does the horn mean?
When we say how much magnetism the horn has, we mean the diameter of the magnet in the horn. For example, 100 magnetism means that the diameter of the magnet is 100 mm. The number of cores refers to the diameter of the voice coil. For example, 100 cores means that the diameter of the voice coil is 100 mm.
