Specifically, the rear seat voice alarm device comprises an amplifier 72 and a loudspeaker 71, wherein each rear seat can be provided with one loudspeaker 71, and the amplifier 72 is shared by a plurality of loudspeakers 71.

Alternatively, the speaker 71 is provided on a surface of the corresponding rear seat facing the front seat.

Specifically, the surface of the front seat of the rear seat facing the rear seat is generally not provided with other structures except for the storage bag, and since the speaker 71 is small in size, the speaker 71 is arranged at the position without occupying the space of the storage bag. In addition, the speaker 71 can be disposed at the same position as the rear seat display 50, so that the structural change of the entire vehicle is small, and the cost is saved.

Alternatively, the speaker 71 is provided in the ceiling of the vehicle. Because the automobile ceiling area corresponding to the rear seats generally has no structures such as a skylight and the like, the loudspeaker 71 is arranged on the automobile ceiling, the original space of other structures is not occupied, the whole automobile is slightly modified, and the design or manufacturing process cost is favorably reduced.

Alternatively, the speaker 71 is provided on the inner wall of the rear door corresponding to the corresponding rear seat.

Specifically, because the body of the passenger is close to the corresponding vehicle door when the passenger opens the door, the loudspeaker 71 is arranged on the inner wall of the rear vehicle door, so that the passenger can be more clearly reminded, and the safety of getting off the vehicle of the passenger is ensured.

Alternatively, referring to fig. 9, the automobile includes:

at least two object detection devices 30;

the partial object detection device 30 is provided on the left rear side of the vehicle body, and the partial object detection device 30 is provided on the right rear side of the vehicle body.

Specifically, the object detecting device 30 disposed on the left rear side of the vehicle body is used for detecting an object on the left rear side of the vehicle, and the object detecting device 30 disposed on the right rear layer of the vehicle body is used for detecting an object on the right rear side of the vehicle.

It should be noted that the foregoing is only a preferred embodiment of the present invention and the technical principles applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious modifications, rearrangements, substitutions and combinations without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail with reference to the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the scope of the present invention.
