Product Number: ADALM2000
Question 1:
Enumerate the main elements that are found in the Loudspeaker Impedance Model
Answer 1:
The main elements of the loudspeaker electrical model are:
- Rdc - dc resistance of the loudspeaker
- L - voice coil inductance
- R - mechanical resistance
- FS - resonant frequency
Question 2:
For the frequency sweep of the loudspeaker circuit in Figure 6, determine the Fs and BW values.
Answer 2:
Consider the plot of the loudspeaker frequency sweep.
We can extract from the plot the following:
- BW ~ 40 Hz
- Fs ~ 265 Hz
