  • Publication number: 20200389730
    Abstract: A frequency compressor of a vibration output apparatus generates a compressed signal by converting frequency components of a mid-band signal into low-band frequency components of a low-band signal by increasing the total number of samples by a factor of n and thus compressing the frequency of amplitude information included in mid-band frequency components of the mid-band signal to 1/n. If the level of a low-band envelope signal is lower than a predetermined threshold level, a vibration signal generator generates a vibration signal by combining the compressed signal with the low-band signal consisting of the low-band frequency components of an acoustic signal. If the level of the low-band envelope signal is higher than the predetermined threshold level, the vibration signal generator generates a vibration signal by directly using the low-band signal. A vibration output unit outputs a vibration on the basis of the generated vibration signal.
