[Abstract]:
Headphones are not just about impedance, they should also be chosen according to individual needs. Headphone parameters mainly include sensitivity, frequency response range, impedance and switching mode.
1. Sensitivity reflects the amount of power that needs to be input in the case of the same loudness. The higher the sensitivity of the headphones, the lower the input power required and the greater the sound output at the same power source.
In Figure 2, the frequency response range refers to the range of sounds that can be represented by the headphones. The frequency response range of a normal earphone is about 20Hz-20KHz, and the frequency response range of the earphone will be larger. For headset parameters, this data is naturally larger as possible.
3, the impedance refers to the size of the earphone itself, the smaller the resistance, the easier the drive is to drive, the larger the resistance, the more difficult the drive. The sound of the reverse group is too confusing, and the higher the impedance of the earphone, the better the sound effect when combined with a sound source with a large output power.
4. Classification of energy conversion modes: mainly dynamic coil type, electrostatic type, moving iron type.
Headphones are not just about impedance, they should also be chosen according to individual needs. Headphone parameters mainly include sensitivity, frequency response range, impedance and switching mode.
1. Sensitivity reflects the amount of power that needs to be input in the case of the same loudness. The higher the sensitivity of the headphones, the lower the input power required and the greater the sound output at the same power source.
In Figure 2, the frequency response range refers to the range of sounds that can be represented by the headphones. The frequency response range of a normal earphone is about 20Hz-20KHz, and the frequency response range of the earphone will be larger. For headset parameters, this data is naturally larger as possible.
3, the impedance refers to the size of the earphone itself, the smaller the resistance, the easier the drive is to drive, the larger the resistance, the more difficult the drive. The sound of the reverse group is too confusing, and the higher the impedance of the earphone, the better the sound effect when combined with a sound source with a large output power.
4. Classification of energy conversion modes: mainly dynamic coil type, electrostatic type, moving iron type.
