Abstract: A signal processing device includes: an obtainer that obtains sound data; a pitch controller that controls pitch of the sound data obtained to increase the pitch by a factor of n (a real number greater than 1); an extractor that extracts frequency components of at least 20 kHz which are included in the sound data whose pitch is controlled; an adder that adds the frequency components extracted to the sound data obtained; and an outputter that outputs sound data to which the frequency components extracted are added.

Abstract: A vehicle approach notification system for notifying approach of a vehicle includes: a first speaker and a second speaker provided in a speaker case included in a vehicle; a sound source that outputs sound signals which are respectively input to the first speaker and the second speaker and correspond to a sound notifying the approach of the vehicle; and a phase controller that controls a phase of at least one sound signal out of the sound signal input to the first speaker and the sound signal input to the second speaker so that sound pressure at left and right of the vehicle caused by the sound output from the first speaker and the second speaker is higher than sound pressure along a longitudinal axis of the vehicle caused by the sound output from the first speaker and the second speaker.

Abstract: A vehicle proximity device includes: an obtainer that obtains a first audio signal obtained by extracting a first frequency band of a first sound source signal and a second audio signal obtained by extracting a second frequency band thereof; a simulated signal processor that generates a simulated signal based on a second sound source signal; a third filter that generates a third audio signal by extracting the first frequency band of the simulated signal; a fourth filter that generates a fourth audio signal by extracting the second frequency band of the simulated signal; a sound pressure adjuster that generates an output audio signal by adjusting the simulated signal to reduce a first difference between the first audio signal and the third audio signal and a second difference between the second audio signal and the fourth audio signal; and an outputter that outputs the output audio signal to the loudspeaker.

Abstract: A vehicle approach notifying device for notifying the approach of a vehicle by causing a loudspeaker to output a warning sound includes: a storage that stores a predetermined threshold of sound pressure; and a controller that: (i) causes a loudspeaker disposed outside a cabin of the vehicle to output the warning sound at a first sound pressure determined in accordance with a speed of the vehicle when a sound pressure of the warning sound acquired by a microphone disposed outside the vehicle is less than or equal to the predetermined threshold; and (ii) causes the loudspeaker to output the warning sound at a sound pressure lower than the first sound pressure when the sound pressure of the warning sound acquired by the microphone exceeds the predetermined threshold.

Abstract: A sound processing device includes: a sound source that outputs a common sound signal to a first speaker for a vehicle exterior and a second speaker for a vehicle interior that are mounted on the vehicle; a notification sound controller that outputs a signal corresponding to a notification sound for notifying an approach of the vehicle to the first speaker based on the sound signal output from the sound source; and an acceleration sound controller that outputs a signal corresponding to an acceleration sound of the vehicle to the second speaker based on the sound signal output from the sound source.
