L 1kHz L 10kHz Inductance at 10kHz Inductance at 10kHz 13.7.3 TS STEP BY STEP Getting TS requires two impedance measurements. As we will use both methods we need three, the first relative to the driver in free air, the second to the driver with a known mass (delta mass) added to the cone, the third to the driver loaded with a known volume (delta compliance). Fig.13.20 shows the results of the three measurements, overlaid in one single graphic. 50.0 CLIO 180.0 Ohm Deg 40.0 108.0 30.0 36.0 20.0 -36.0 10.0 -108.0 0.0 -180.0 10 100 1k Hz 10k 20k Figure 13.20 The black curve refers to free air, the red to delta mass, the green to delta compliance. As you can see adding a Mass determines lowering Fs while loading the cone with a closed volume will increase Fs. Always check this is the case to avoid errors in the post processing routine. As deriving TS parameters can be performed at any successive time after the impedance measurements has been taken, we suggest to save them with meaningful names as well as to use the Notes Dialog to store the measuring conditions as mass weight and/or volume. The last step before pressing Go in the TS dialog is to measure both the voice coil DC resistance and the effective cone diameter in millimeters. In this example they are 6.41 Ohm and 133mm. Finally we select File Data as data origin and pressing Go we get the following prompt Dialog 140 Chapter 13 - Measuring impedance and T&S parameters
After right values have been typed in clicking Ok we will prompt for the file name. The file required here is the free air impedance measurement. Opening the file we get this partially filled TS parameters screen. Now we can save this result for later use or proceed immediately for the missing parameters. Notice that the two Buttons for Delta Mass and Delta compliance that were disabled before are now enabled. We Click on the Delta Mass Button, type in the required values and, finally, after we have choose the impedance file obtained with the added mass, we get our completely filled TS parameters screen Chapter 13 - Measuring impedance and T&S parameters 141
