What does damping coefficient mean? What is the damping coefficient KD value? [Copy link]

The power of science and technology is everywhere in our lives. Many things we use in our daily lives are produced because of the high level of science and technology, and these products have been widely used all over the world. Some scientific terms that are not very common in life have also entered people's lives with the advancement of science and technology. For example, the damping coefficient is an uncommon but very important thing. Today we will talk about what the damping coefficient means?

What does damping coefficient mean? What is the damping coefficient KD value?

What does damping coefficient mean?

The damping factor is the ratio of the rated load (speaker) impedance of the amplifier to the actual impedance of the power amplifier. A larger damping factor means that the output resistance of the power amplifier is much smaller. The damping factor is also the ability of the amplifier to control the cone movement of the speaker after the signal disappears. Amplifiers with high damping factors are more like short circuits for the speaker, which can reduce the probability of vibration when the signal stops. The output impedance of the power amplifier frequency will also directly affect the low frequency in the speaker system, which will lead to the low efficiency characteristics of the system.

What is the definition of damping coefficient KD?

What does damping coefficient mean? You need to know the meaning of damping coefficient KD. In damping coefficient, KD is equivalent to the rated output impedance of the amplifier/output internal resistance of the amplifier. However, since the output internal resistance of the amplifier is actually the electrical damping period of the sound system, the KD value determines the amount of electrical damping that the speaker is subjected to. Generally speaking, the larger the KD value, the greater the electrical damping. Of course, the larger the KD value of the amplifier, the better. Because a large KD value will make the electrical damping of the speaker too heavy, which will increase the time it takes for the pulse front to establish, reducing the transient response index.

Now everyone should know what the damping factor means? In fact, the damping factor is a value in the power amplifier, which is the ratio of the rated load impedance of the amplifier to the century impedance of the power amplifier.
