L 1kHz L 10kHz Inductance at 1kHz Inductance at 10kHz 13.7.3 T&S STEP BY STEP Getting T&S 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 results in 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 T&S parameters can be performed at any subsequent time after the impedance measurements has been taken, we suggest you save them with meaningful names as well as using the Notes Dialog to store the measuring conditions as mass weight and/or volume. The last step before pressing Go in the T&S 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 the data origin and pressing Go we get the following prompt Dialog 170 Chapter 13 - Measuring impedance and T&S parameters
After the correct values have been typed in and clicking OK we will be prompted for the file name. The file required here is the free air impedance measurement. Opening the file we get this partially filled T&S 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 and type in the required values and, finally, after we have choose the impedance file obtained with the added mass, we get our completely filled T&S parameters screen Chapter 13 - Measuring impedance and T&S parameters 171
