  "textContent": "A lamp for a vehicle includes a lamp housing part having an internal space to accommodate a light source, an outer lens part coupled to one side of the lamp housing part and to cover the internal space, and a vibration part fixed to the outer lens part. The vibration part includes a polarized piezoelectric element, and a first electrode and a second electrode provided to respectively face two opposite sides based on a direction in which the piezoelectric element is polarized. In response to a change in voltage over time being applied to the first electrode and the second electrode, the piezoelectric element outputs a sound. The piezoelectric element is in contact with and fixed to one side of the outer lens part.",
