摘要： PROBLEM TO BE SOLVED: To provide a speaker control circuit which avoids overlapping of two bit groups transformed into analog signals.
SOLUTION: The speaker control circuit with a speaker capsule (18) is composed of a bit splitter (6) which divides data items representing sound signals into a high-order bit group and a low-order bit group, and two D/A converters (1, 2) which perform D/A conversion of the high-order bit group and the lower-order bit group. Digital input of the D/A converters (1, 2) is connected to output of the bit splitter (6). While a complement stage (5) for denying bit groups is series-connected to the D/A converters (2, 1), the output of D/A converters (1, 2) are one terminal of the speaker capsule (18), the other output of D/A converters (2, 1) is connected to the other terminal of the speaker capsule (18).
