A speaker for vehicle which is installable in a space adjacent to a passenger room in a vehicle body, comprising:

• a diaphragm facing the passenger room;
• a conversion portion disposed on a backside of the diaphragm, the conversion portion converting an electric signal into a driving force for a mechanical displacement to be applied to the diaphragm;
• and
• a weight mounted on the backside of the conversion portion,
• wherein the weight includes:
• a coupling part coupled with a back part of the conversion portion;
• and
• a weighting part having a shape in which the length in a diameter direction extending perpendicularly to a depth direction that extends from the coupling part toward the back part is longer than that in the depth direction, and having a mass capable of suppressing a vibration of the conversion portion.
