Figure 2-17 shows a differential speaker circuit, Figure 2-18 shows a single-ended speaker circuit
and Table 2-8 gives the speaker specifications.
Figure 2-17: Differential Speaker Circuit
Important: For safety regulations it is important to place series resistors on the speaker output
lines, as illustrated in Figure 2-17. The resistors value should be R = 0
Ω at the
design stage, but may be changed to a different value during audio safety testing, in
case speaker level limitation is required.
