Patent attributes
The present invention relates to an adaptive haptic signal generating device, which includes: a frequency analysis unit converting and analyzing a received audio signal into a frequency domain; a frequency equalizer unit suppressing or amplifying a specific frequency interval of the audio signal converted into the frequency domain; a haptic event extraction unit extracting a haptic event signal corresponding to a case of a specific threshold or more in the suppressed or amplified frequency domain; a haptic signal generation unit generating a haptic signal corresponding to the haptic event signal; and a control unit counting the number of generation times of the extracted haptic event signal for each frequency, and increasing a frequency gain of a frequency corresponding to a haptic event signal which is generated at a predetermined number of times or more.
