Adaptive haptic signal generating device and method thereof

An adaptive haptic signal generating device comprising:

• a filter unit filtering a specific frequency interval of a received audio signal;
• an amplifier unit suppressing or amplifying the filtered audio signal;
• a haptic event extraction unit extracting a haptic event signal corresponding to a case of a specific threshold or more in the audio signal suppressed or amplified by the amplifier unit;
• a haptic signal generation unit generating a haptic signal corresponding to the haptic event signal;
• and
• a control unit
• counting a number of generations of the extracted haptic event signal,
• identifying the number of generations of the extracted haptic event signal for each frequency corresponding to the extracted haptic event signal,
• detecting a particular frequency having the identified number of generations, which is equal to or higher than a predetermined number, and
• increasing an amplification gain of the detected particular frequency.

An adaptive haptic signal generating method comprising:

• converting and analyzing a received audio signal into a frequency domain;
• suppressing or amplifying a specific frequency interval of the audio signal converted into the frequency domain;
• extracting a haptic event signal corresponding to a case of a specific threshold or more in the suppressed or amplified frequency domain;
• and
• generating a haptic signal corresponding to the haptic event signal, and further comprising:
• counting a number of generations of the extracted haptic event signal;
