Problems solved by technology

However, this can also create problems as electric vehicles are too quiet
For example, in front of a vehicle, when a pedestrian walks with his back to the vehicle, it is often difficult for the pedestrian to notice that the vehicle is gradually approaching, which poses certain hidden dangers to the safety of the pedestrian.

Abstract

The invention discloses a device for generating warning sound of a vehicle and a vehicle. The device for generating warning sound of the vehicle comprises a sounding system. The sounding system comprises a microphone, a signal-processing circuit, and a loudspeaker. The microphone is used for detecting background noise to generate a background noise signal. The signal-processing circuit is used for receiving the background noise signal output by the microphone, amplifying the power of the background noise signal and then outputting the background noise signal with amplified power to the loudspeaker. The loudspeaker is used for playing the signal output by the signal-processing circuit. The device for generating warning sound of the vehicle further comprises a device for adjusting the relative position of the microphone and the loudspeaker. The device for adjusting the relative position of the microphone and the loudspeaker is used for adjusting, when a warning condition is triggered, the relative position of the microphone and the loudspeaker in order that the sounding system forms a closed-loop audio feedback loop and sounds. The invention also discloses a vehicle. The device for generating warning voice of the vehicle may sound in a simple way in order to draw pedestrians' attention for improving safety.

Description

technical field [0001] The present invention relates to vehicle technology, and more particularly, to a vehicle warning sound generating device and a vehicle. Background technique [0002] With the popularization of electric vehicles, the problems of air pollution and environmental noise pollution caused by traditional fuel vehicles have gradually disappeared. However, this can also create problems because electric vehicles are too quiet. For example, in front of a vehicle, when a pedestrian walks with his back to the vehicle, it is often difficult for the pedestrian to notice that the vehicle is gradually approaching, which poses certain hidden dangers to the safety of the pedestrian. Therefore, it is necessary to propose a vehicle warning sound generating device. Contents of the invention [0003] An object of the present invention is to provide a new technical solution for a vehicle warning sound generating device. [0004] According to a first aspect of the present ...
