Abstract
A speaker driving device including a setting part configured to set at least one parameter stipulating an equivalent circuit of a first speaker unit as a first parameter, a first calculator configured to change a first frequency response based on the first parameter, the changed first frequency response being applied to an input signal, the first calculator configured to perform amplitude control on a signal obtained with the changed first frequency response to output a first calculation signal, and a driving signal generator configured to generate a drive signal for driving a speaker unit based on the first calculation signal.
Claims18
A speaker driving device comprising:
- a setting part configured to set at least one parameter stipulating an equivalent circuit of a first speaker unit as a first parameter;
- a first calculator configured to change a first frequency response based on the first parameter, the changed first frequency response being applied to an input signal, the first calculator configured to perform amplitude control on a signal obtained with the changed first frequency response to output a first calculation signal;
- and
- a driving signal generator configured to generate a drive signal for driving a speaker unit based on the first calculation signal.
A speaker driving device comprising:
- a setting part configured to set at least one parameter stipulating an equivalent circuit of a first speaker unit as a first parameter;
- a first calculator configured to change a first frequency response based on the first parameter, the changed first frequency response being applied to an input signal, the first calculator configured to perform amplitude control on a signal obtained with the changed first frequency response to output a first calculation signal;
- a driving signal generator configured to generate a drive signal for driving a speaker unit based on the first calculation signal;
- and
- a speaker unit driven by the drive signal.
A computer-readable storage medium having a program stored thereon, the program causing a computer to:
- set at least one parameter stipulating an equivalent circuit of a first speaker unit as a first parameter;
- change a first frequency response based on the first parameter, the changed first frequency response being applied to an input signal;
- perform amplitude control on a signal obtained with the changed first frequency response to output a first calculation signal;
- and
- generate a drive signal for driving a speaker unit based on the first calculation signal.
