Various performance parameters of multimedia speakers, their commonly used parameters mainly include: Z, FO, η0, SPL, QTS, QMS, QES, VAS, MMS, CMS, SD, BL, xmax, Gap Gauss. The physical significance of the species parameters, then the multimedia speakers manufacturer-Wujin Yueda electro-sound sound will be briefly introduced for you.

Z: refers to the impedance value of the speaker, including: rated sensor resistance and DC resistance. (Unit: Ohm/OHM), usually refers to the rated impedance.

FO (minimum resonance frequency) refers to the frequency corresponding to the first large value of the speaker impedance curve.

的0 (the efficiency of the speaker): refers to the ratio of the speaker output sound and input power ratio.

SPL (Sound voltage level): When the speaker is voltage of the electrical power of the rated impedance 1W. At the point of 1m from the horn on the reference shaft.

QTS: The total quality of the speaker is due to the value.

QMS: The mechanical quality of the speaker.

QES: The electrical quality of the speaker.

VAS (effective volume of the speaker): refers to the volume of the sound of the air in the rigid container with the sound of the speaker unit in the rigid container.

MMS (vibration quality): refers to the total quality of the vibration components during exercise, including the total quality of the vibration components, including the drum paper, the sound coil, and the bomb wave.

CMS (Lishun): It refers to the softness of the supporting components of the speaker vibration system. The larger the value, the softer the entire vibration system of the speaker.

SD (vibration area): It refers to the effective vibration area of the drum/vibration membrane during the vibration process of the speaker. Unit: square meter (m2).

BL (magnetic force): The multiplier of the gap magnetic induction intensity and the effective sound coil line. Unit: (T*M). XMAX: The linear itinerary of the sound coil exercises during the vibration process. Unit: millimeter (mm).

Gap GAUSS: Magnetic induction strength value. Unit: Tesla.

For these parameters of multimedia speakers, we can do some understanding and understand the corresponding meaning, so as to better do the maintenance of multimedia speakers.
