Sound production device for vehicle

A sound production device for a vehicle includes: a speaker that causes a diaphragm to vibrate thereby producing sound; and a housing receiving the speaker and having a sound passage through which the sound produced by the speaker passes and a sound emission hole that causes the sound passed through the sound passage to externally emit. Plural resonant chambers having different resonant frequencies are defined in the sound passage, such that the sound passage has a labyrinth structure that is able to prevent a foreign substance form entering the diaphragm from the sound emission hole.
