It should be noted that a configuration may be adopted in which only one engine type engine sound is stored in one storage device 1 and an engine sound of a different vehicle type is selected by replacing the storage device 1.

Next, a description will be given of a third embodiment in which the engine sound is changed and reproduced according to the engine speed condition.

More specifically, the reproduction device 2 is provided with a processing mechanism 4 for reproducing the engine sound stored in the storage device 1 by changing the engine sound in accordance with the rotation speed of the vehicle engine or the traveling speed of the vehicle. This is device 2.

More specifically, for example, the processing mechanism 4 for changing the reproduction volume of the engine sound stored in the storage device 1 in accordance with the rotation speed of the vehicle engine in the processing and reproduction device 2.
A predetermined engine sound is reproduced by using the equalizer function of the audio device as the processing mechanism 4 and the frequency of the reproduced engine sound is changed according to the rotation speed of the vehicle engine to reproduce the predetermined engine sound. And

An engine speed detecting mechanism similar to that of the second embodiment is provided.

Therefore, in the third embodiment, the second embodiment is used.
Since the pseudo engine sound close to the original engine sound is reproduced in the same manner as that described above, the user can enjoy driving while listening to the realistic and realistic pseudo engine sound.

Further, if a speed detecting mechanism is provided in the same manner as in the second embodiment to change the engine sound in consideration of the running speed of the vehicle, a more realistic and realistic simulated engine sound is provided. Is obtained.

Further, the third embodiment may be combined with the first embodiment. That is, the storage device 1 stores the engine sounds of many types of vehicles, while the selection reproduction device 2
The apparatus may be provided with a selection mechanism 3 for manually selecting an engine sound of a desired vehicle type and a processing mechanism 4 for changing and reproducing the engine sound according to the rotation speed of the vehicle engine or the traveling speed of the vehicle. According to this configuration, the device has both the effects of the first and third embodiments, so that it is more practical.

Further, a configuration in which the second embodiment and the third embodiment are combined may be adopted. That is, the storage device 1 stores the engine sounds of various types of engine speed conditions, while the selection and reproduction device 2 includes a selection mechanism 3 for automatically selecting the engine sounds according to the engine speed conditions, An apparatus configuration including a processing mechanism 4 that changes and reproduces according to the rotation speed of the engine or the traveling speed of the vehicle,
With this configuration, the apparatus has both the effects of the second and third embodiments, so that the apparatus is more practical.

Further, the first embodiment, the second embodiment, and the third embodiment may be combined. That is, the storage device 1 stores the engine sounds of many types of vehicles, and further stores the engine sounds of various types of engine speed for each type of vehicle. And a selection function 3 having a selection function for automatically selecting an engine sound according to the engine speed condition, and reproducing the engine sound by changing the engine sound according to the rotation speed of the vehicle engine or the traveling speed of the vehicle. Processing mechanism 4
In this configuration, since the device has all the effects of the first, second, and third embodiments, it is the most practical embodiment in this embodiment.

This will be described more specifically.

As the reproducing apparatus 2, for example, a vehicle audio system that can be mounted in a vehicle is used.
