1.Directivity
Directivity refers to the characteristic that the sound pressure radiation ability of loudspeaker varies with frequency in different directions,or the ability of loudspeaker sound wave to radiate to all directions of space.The higher the signal frequency of the input speaker, the stronger the directivity.
2. Total quality factor
The total quality factor of the horn,also known as Qts value,is used to reflect the speed of energy consumption of the vibration system,that is,the loss of the vibration system.
3. Equivalent volume
Speaker equivalent volume refers to the equivalent air volume of speaker vibration system. The larger the caliber of the speaker,the larger its equivalent volume.
4. Magnetic induction intensity and flux
Magnetic induction intensity,we xuanda speaker factory also called it magnetic gap intensity, used to represent the quality mark of the magnetic field intensity in the speaker air gap.
The magnetic flux is equal to the product of the magnetic induction intensity and the average area of the air gap.
5. Equivalent vibration radius
The speaker's equivalent vibration radius is also known as the effective area of the diaphragm. It represents the area that contributes to sound radiation,generally refers to the length from the center of the diaphragm to the middle of the ring.
6. Linear range
The linear range of speaker refers to the maximum linear displacement of the diaphragm.When the speaker is working,if the displacement of the diaphragm exceeds the linear range,the playback distortion will increase.
