A vehicle is provided and includes a camera that photographs a face of a driver, a sensor that obtains skin information of the driver, a speaker, and a controller. The controller determines a physical condition of the driver based on at least one of a face image of the driver and the skin information of the driver, determines a sound source and a parameter based on the physical condition of the driver, generates a driving sound by reflecting driving information of the vehicle in the sound source and the parameter, and operates the speaker to output the driving sound.

Vehicle and control method thereof

A vibration reducing device is attached to a structure and blocks sound transmitted through the structure. The vibration reducing device includes a unit structure having a target frequency band, the unit structure including a plurality of unit cells, each formed of an acoustic meta-material and having a different target frequency, the unit cells being connected through first bridges; and a predetermined number of unit structures being connected through second bridges and attached to the structure, where each of the unit cells comprises: a mass portion of which a size is set according to the target frequency; a base frame formed as a quadrangular frame, the mass portion being eccentrically disposed in the base frame; and a support portion that connects the mass portion and the base frame, the support portion having a size that is set according to the target frequency.

Device for reducing vibration

An embodiment vehicle includes a camera, a speaker, and a controller electrically connected to the camera and the speaker, wherein the controller is configured to acquire a first external image outside the vehicle from the camera, input the first external image to a pre-trained first neural network and extract a first feature corresponding to the first external image, and control the speaker to output a first sound sample among a plurality of sound samples, based on a comparison of the first feature and pre-stored features corresponding to the plurality of sound samples.
