Speaking of earphone speakers, we have to compare it with mobile phone speakers. The earphones we use are usually close to the earphones, and the mobile phone speakers are isolated from the air for a certain distance before being sent to the ears. Therefore, the mobile phone speakers have to require sound. The bigger the better, but the earphone speaker is gone. Who turns on the sound loudly when listening to the earphone?
To explain: headphones can be roughly divided into headphones and earplugs!
Commonly used magnets are divided into: ferrite (black magnet), neodymium iron (high coercivity-white magnet)
Our requirements for headphones are: the higher the sound quality, the higher the quality of the headphones. The quality of the headphones is determined by the speakers and the cavity!
The quality of the headphone speaker is not determined by the quality of the magnet. The magnet can only be said to be proportional to the sensitivity of the speaker. The better the magnet is, the higher the sensitivity (higher sensitivity is not necessarily good sound quality), because the headset is driven by a large speaker unit, and there is enough space to put it. magnet!
For earplugs, don’t choose black magnets, because earplugs are originally required to be small, which limits the size of the magnet. If the size of black magnets is small, the magnetic force will be greatly weakened, and you will feel that the earphones have no thrust, so black magnets for earplugs are 100 % There is no white magnet.
Summary: As long as there is enough space to put the magnet, the two have their own advantages. If the space of the magnet is limited, of course it is a white magnetic speaker!
