Abstract: A vehicle proximity notification device that notifies proximity of a vehicle by causing a speaker disposed outside a vehicle interior of the vehicle to output a warning sound. The vehicle proximity notification device includes: a controller that, when a sound pressure of a sound collected by a microphone disposed outside the vehicle interior exceeds a first threshold, sets a sound pressure of the warning sound output by the speaker to a level lower than the sound pressure of the warning sound output by the speaker when the sound pressure of the sound collected by the microphone is lower than or equal to the first threshold.

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: Provided is a vehicle approach notification device that can easily output a warning sound in which a discomfort feeling brought to an occupant is reduced while ensuring a necessary sound pressure. A vehicle approach notification device includes: a sound source; first and second amplifiers; a first speaker system including a first speaker and a second speaker that outputs a sound having an opposite phase to a sound output from the first speaker; and a second speaker system including a third speaker that outputs a sound having a same phase as the sound output from the first speaker and a fourth speaker that outputs a sound having an opposite phase to the sound output from the third speaker, wherein the first speaker system and the second speaker system are disposed so that the first speaker and the third speaker are located closer to a longitudinal center plane of the vehicle than the second speaker and the fourth speaker.
