Abstract: The present invention provides a vibration audio system for transmitting an audio signal outputted from a sound source to a listener in the form of vibration while reducing output level of the signal and power consumption. The system includes an envelope detection unit (204) for detecting an envelope signal of the audio signal outputted from a sound source, a vibration transmission member for allowing the listener to perceive vibration of a low-frequency sound outputted from a low-frequency output speaker that outputs audio signals, and a frequency conversion unit (205) for generating an audio signal frequency-converted on the basis of resonant frequencies by multiplying the envelope signal by sine waves having the same frequencies as resonance frequencies obtained from an impulse response of the low-frequency output speaker disposed in the vibration transmission member. The audio signal frequency-converted by the frequency conversion unit (205) is outputted from the low-frequency output speaker.

Abstract: Disclosed is a piezoelectric actuator drive unit that includes a piezoelectric actuator drive amplifier and a piezoelectric actuator drive unit power supply. Combinations of high and low signal levels of a first control signal, which controls the supply voltage and amplifier bias voltage of the piezoelectric actuator drive amplifier, and a second control signal, which controls the driving force of the piezoelectric actuator drive amplifier, are associated with a haptic feedback function, a receiver function for generating an audio output, and a speaker function for generating music or the like. Thus, the piezoelectric actuator drive unit, which vibrates a piezoelectric actuator, is adapted to the haptic feedback function, the receiver function, and the speaker function, and can optimize its power and drive amplifier characteristics.
