Speaker driving device

A speaker driving device comprising:

• a first calculation unit configured to output a first calculation signal obtained from a first input signal based on response characteristics according to a first parameter, the first parameter defining an equivalent circuit of a first speaker unit;
• a first driving signal generation unit configured to generate a second calculation signal and a first driving signal based on a fourth calculation signal and the first calculation signal, the first driving signal for driving a first output speaker unit, the second calculation signal including a characteristic value corresponding to the first calculation signal;
• a third calculation unit configured to generate a third calculation signal from a second input signal based on response characteristics according to a third parameter, the third parameter defining an equivalent circuit of a third speaker unit;
• and
• a second driving signal generation unit configured to generate the fourth calculation signal and a second driving signal based on the second calculation signal and the third calculation signal, the second driving signal for driving a second output speaker unit, the fourth calculation signal including a characteristic value corresponding to the third calculation signal.
