A speaker is provided to prevent a coupling force of a bolt from being weakened due to vibration by absorbing the vibration generated when reproducing the sound. A speaker includes a housing(110), a base(120), and an elastic unit(130). The housing includes a protruded boss. The penetration hole is formed so that the boss penetrates the base. A sound unit is mounted in the center of the base. The elastic unit is mounted on the boss in contact with the base. The fixing unit is formed in the end part of the boss. The fixing unit is larger than the outer circumference of the elastic unit so that the elastic unit is not separated. |
