Abstract: A vehicle approach warning apparatus outputting a warning sound signal for outputting a warning sound, and generating the warning sound according to the warning sound signal from a speaker, and notifying a pedestrian around a vehicle that the vehicle approaches to the pedestrian is provided. The vehicle approach warning apparatus includes a memory portion, a signal generation portion, a level adjustment portion, a signal synthesizing portion, and an amplifier. The memory portion stores a first sound source data for generating a signal of a low frequency component, and a second sound source data for generating a signal of a high frequency component. The signal generation portion generates the signal of the low frequency component, and the signal of the high frequency component. The level adjustment portion adjusts a level of the signal of the low frequency component and the high frequency component.

Abstract: A vehicle approach notification apparatus includes a first sounding signal generation portion that generates a first sounding signal based on a first sound source data; a second sounding signal generation portion that generates a second sounding signal based on a second sound source data; and a combination portion that combines the first sounding signal with the second sounding signal to generate a notice sound signal. The first sounding signal generation portion changes a frequency and an output level of the first sounding signal depending on a speed of the vehicle. The second sounding signal generation portion changes an output level of the second sounding signal depending on the speed of the vehicle while holding a frequency of the second sounding signal to be constant.

Abstract: A vehicle approach alert device includes: a memory memorizing a warning sound source data for emitting a warning sound from an external sound emitting unit and a canceling sound source data for emitting a canceling sound from an internal sound emitting unit. The canceling sound cancels the warning sound transmitted from the external sound emitting unit to inside of the vehicle. The vehicle approach alert device further includes: a control part configured to read the warning sound source data from the memory to cause the external sound emitting unit to emit the warning sound based on the warning sound source data, and to read the canceling sound source data from the memory to cause the internal sound emitting unit to emit the canceling sound based on the canceling sound source data to be synchronized with the warning sound.

Abstract: In a vehicle approach notification device for notifying approach of a vehicle by emitting a notification sound according to a synthetic sound signal composed of a plurality of frequency components from a speaker, a vehicle speed specifying portion specifies a speed of the vehicle, and a synthetic sound signal generating portion generates the synthetic sound signal. The synthetic sound signal generating portion generates the synthetic sound signal such that the frequency component that belongs to a second frequency range in which a variation in sound pressure outputted from the speaker is equal to or smaller than a predetermined magnitude is shifted according to a change in the speed of the vehicle, without shifting the frequency component that belongs to a first frequency range in which the variation in sound pressure outputted from the speaker is greater than the predetermined magnitude.

Abstract: A vehicle approach alert device that outputs an approach report sound from a sounding body includes: a memory part in which data of the approach report sound is memorized; a signal generator that generates a voltage waveform signal of the approach report sound based on the data of the approach report sound; a calculator that calculates a temperature of the sounding body; and a correct part that corrects the approach report sound based on the temperature of the sounding body. The calculator acquires information about a temperature detected by a temperature sensor located at a position different from the sounding body in the vehicle, and estimates the temperature of the sounding body based on the temperature detected by the temperature sensor.
