That is, the present invention relates to an apparatus and method for generating a virtual engine sound capable of constituting and controlling a speaker for generating a virtual engine sound and a horn for generating a vehicle alarm sound.

Generally, a hybrid vehicle or an electric vehicle is driven without noise since the motor is not driven when traveling for 0 to 20 km, and noise generated in the vehicle is very low. Therefore, it is difficult for the pedestrian, especially the visually impaired, to judge whether or not the vehicle is approaching.

In order to prevent this problem, it has been legalized to apply a Virtual Engine Sound system that warns pedestrians to approach a vehicle by outputting a virtual engine sound to a hybrid car or an electric car in North America and Japan.

Therefore, a virtual engine sound system (VESS) has been studied in which a virtual engine sound is outputted through a speaker to allow the pedestrian to easily recognize the approach of the vehicle.

For example, in Korean Patent Laid-Open Publication No. 2014-0080317, an indoor sensor for measuring whether a vehicle is indoors, a virtual engine sound generator for generating a virtual engine sound of the vehicle, and data measured by an indoor sensor are received And controlling the virtual engine sound to be transmitted to the virtual engine sound generating unit.

However, the generation of a virtual engine sound and the occurrence of a vehicle alarm sound have a common feature that a warning sound is generated in order to prevent accidents. However, since the generator is separately configured, the weight of the vehicle is increased or the installation process is increased, .

In addition, when the virtual engine sound speaker is disposed behind the front grille, there is a problem that the diaphragm, that is, the cone paper, may be damaged due to high pressure washing or wind that enters during driving.
