This is to build a fixed magnetic field with a magnetic balance.
There is a magnet on the horn. I think everyone knows what role the magnet plays on the horn. This estimate can be said to be few, and today, Xiamen horn magnet manufacturer GME Xiaobian will share with you about the speaker magnet.
1. What is a horn magnet?
Simply speaking, it is the magnet in the horn device, which is the horn magnet, which is called horn magnet.
2. What role does the magnet play on the horn?
There is a coil (called a voice coil) on the cone of the horn. When the audio signal is applied to the voice coil, the current, the intensity of the current, the direction, etc. are formed, and the voice coil changes its position in the magnetic field, and the vibration of the voice coil. Drive the paper cone to vibrate, and the air will vibrate, and the horn will sound.
3, the speaker magnet is bigger, the louder the sound
Many people will definitely answer, that's for sure, in fact, the speaker of the stereo is not the bigger the magnet, the better: because the magnet is divided into high density, low density, strong magnetic, weak magnetic, etc. If it is a low-density weak magnet, Its effect is certainly not good, and it is not convenient to install it in a large size.
4. What kind of magnet sound is good for the speaker (audio)?
The magnet horn generally uses a ferrite magnet and a neodymium iron boron permanent magnet. Ferrite permanent magnets are generally used for middle and low-end headphones. NdFeB permanent magnets are used for high-end headphones. The sound quality is very good, the elasticity is good, the details are good, the sound quality is good, and the sound field is positioned accurately.
Reviews:
Myapple: The current cottage units are all made up of garbage magnets.
Ltjd007: Personally feel that the magnetic force is not proportional to the size of the magnetic steel, the magnet is not the same! The strong magnetic control is of course excellent, but there should be a balance!
AKG: In a word, the size of the magnet of the horn is determined by the design of the horn, not to save the cost of the magnet.
Foshun Laoye: It is not the bigger the better, it is the material problem of magnetic steel. It should be suitable for the design parameters of the horn. How big is the horn magnet with strong magnetic?--------
The main specifications of NdFeB horn magnet are: φ6*1, φ6*1.5, φ6*5, φ6.5*1.5, φ6.5*φ2*1.5, φ12*1.5, φ12.5*1.2, etc., in millimeters.
Horn magnetic plating: Generally, galvanizing is selected. According to environmental protection requirements, environmentally friendly zinc plating is also possible.
