Abstract
A tactile sensation providing apparatus includes a linear resonant actuator; and circuitry configured to provide a pulse wave to the linear resonant actuator as a driving signal. The circuitry is further configured to, when a frequency of the pulse wave is smaller than a resonance frequency of the linear resonant actuator, set a pulse width of the pulse wave at a value smaller than a half of a reciprocal of the frequency of the pulse wave.
