The effect of magnet performance on the sound output quality of speakers
In the case of the same magnet volume and the same voice coil, the performance of the magnet has a direct impact on the sound quality of the speaker:
The greater the magnetic flux density (magnetic induction) B of the magnet, the stronger the thrust acting on the sound film.
The greater the magnetic flux density (magnetic induction) B, the higher the relative power and the higher the sensitivity of the speaker. The earphone sensitivity is the sound pressure level that the earphone can emit when a 1mw, 1khz sine wave is input to the earphone. The unit of sound pressure is dB (decibel). The greater the sound pressure, the greater the volume, so the higher the sensitivity, the lower the impedance, and the easier it is for headphones to produce sound.
The greater the magnetic flux density (magnetic induction) B, the lower the overall quality factor Q value of the speaker. Q value (quality factor) refers to a set of parameters of horn damping coefficient,
The greater the magnetic flux density (magnetic induction) B, the better the transient state. Transient can be understood as "fast response" to the signal. Earphones with good transient response should respond immediately as soon as the signal comes, and stop abruptly as soon as the signal stops. It will never be sloppy. Drums and symphonies with larger scenes will lead you to it. The transitional part of the ensemble is most obvious.
