原文（中国語）

A lamp for a vehicle is provided. The lamp 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 configured to cover the internal space, and a vibration part fixed to the lamp housing part or the outer lens part. The vibration part includes a polarized piezoelectric element that is polarized in a direction D, and a first electrode and a second electrode respectively facing two opposite sides based on the direction Din which the piezoelectric element is polarized. The piezoelectric element outputs a sound by being vibrated by a change in voltage applied to the first electrode and the second electrode over time.
