Headphone Impedance: Headphone Impedance - Introduction, Headphone Impedance - Remark

The impedance of the headphones is the abbreviation of the AC impedance. The impedance refers to the impedance in the circuit with resistance, inductance and capacitance, and the impedance is the impedance (in ohms). In general, the smaller the impedance, the easier it is to sound the headphones, the easier it is to drive. The impedance of the headset is changed with the frequency of the audio signal that it replays. Generally, the headphone impedance is much larger in the high frequency [1], so the attenuation of the low frequency is less than the high frequency; for most headphones, The output impedance will make the sound darker and more mixed (at this time the power amplifier on the headphone drive unit control will become weak), but some of the headphones need to be better in the high impedance. If the headphones are sharp and harsh, consider increasing the effective output impedance of the headphone jack; if the headphones are dim and turbo and driven by a power amplifier, consider reducing the effective output resistance.

Headphones in the desktop or amplifier, VCD, DVD TV and other headphone jack output on the machine, the general use of high-impedance headphones more appropriate. If you use low-impedance headphones, be sure to put the volume down and then plug in the headset, and then a little bit of the tune up to prevent headphones overload the headset burnout or voice coil deformation caused by broken sound.

Headphone Impedance - Headphone Impedance - Remark

Low-impedance headphones are generally easier to push, so Walkman, MP3 and other portable, power-saving machines should choose low-impedance headphones. But also pay attention to the sensitivity to be high, for Walkman, MP3 sensitivity index is more important. Of course, the higher the impedance of the headset with the output power of the sound source when the sound better.

Headphone impedance _ headphone impedance - a measure method

Headphone impedance is generally how to measure it? Is not any kind of headphones as long as the impedance is good? In fact, this is not the case.

The impedance of the headset is the abbreviation of the AC impedance, the smaller the impedance, the easier it is to headphones, the easier it is to drive.

But also pay attention to the sensitivity to be high, for Walkman, MP3 sensitivity index is more important. Of course, the higher the impedance of the headset with the output power of the sound source when the sound better.

Headphone impedance _ headphone impedance - the size of the impedance

Impedance does not mean the size of the resistance of the headset itself! Impedance matching can increase the power of the headset, headphones, the smaller the better self-resistance. The smaller the self-resistance, the easier it is to drive the headphones; the greater the self-resistance, the less likely to drive. General Walkman headphone impedance of 16Ω-64Ω. General headphone impedance at low frequency minimum, and low frequency attenuation is less than high frequency. For most headphones, increasing the output impedance will make the sound darker and more mixed (at this time the power headphones on the headphone drive unit control will be weakened), but some of the headphones need to be better in the high impedance. The sound of the headphones will sound somewhat mixed, and for low-impedance headphones (usually less than 50 ohms) for a variety of portable players such as CDs, MDs, or MP3s, this is because these low-impedance headphones compare Easy Cheap Beats By Dr Dre" href="/">Cheap Beats By Dr Dre to drive, while attention to high sensitivity, on the Walkman, MP3, MP4, CD, the sensitivity index is more important. Of course, within a certain limit, the higher the impedance of the headset with the output power of the sound source when the sound better.

The size of the headphone impedance and headphone sound quality is also closely linked, the impedance is with the frequency and change, the impedance of the headset at low frequencies smaller, high frequency, so for most headphones, the increase in impedance will make the sound Become more dim.

How much is the headphone impedance? According to the different effects of the sound, the impedance size is different, the earliest impedance of the earphone function is the smaller the headphone impedance, the more easily the headset is driven, the greater the sound of its issue. vice versa. The following Xiaobian to talk about the headset impedance.
