Speaker woofer what Q value is good
The higher the quality factor of the loudspeaker unit, the more difficult the resonant frequency is. The low frequency characteristic of the loudspeaker is usually determined by the quality factor of the loudspeaker unit and the resonant frequency, where the size of the quality factor is related to the sound pressure at the resonant frequency at the loudspeaker unit.
Generally requires a low Q value, but not the lower the better.The quality factor of the loudspeaker unit is a very important parameter that must be understood before designing and producing a speaker.
When the Q value is too high, the speaker is in an underdamped state, and the low frequency is excessively strengthened. The larger the Q value, the steeper the peak.So we say that the quality factor of the speaker that can not be too high can not be too low, usually take 0.2 ~ 0.5 is appropriate.
When the Q value is too low, the output sound pressure of the loudspeaker is not falling rapidly at F0, and the loudspeaker is in a damping state, causing the low frequency attenuation to be too large.
In the impedance characteristic curve of the loudspeaker unit, it indicates the sharpness of the impedance curve at the resonant frequency of the impedance curve, which reflects the damping state of the loudspeaker vibration system to a certain extent.
