PROBLEM TO BE SOLVED: To provide a vibration speaker provided with a sound generating function and a vibration generating function that attains a low profile by integrating the sound generating function and the vibration generating function and prevents a degradation in sound quality and reduction in vibration amount. SOLUTION: A vibration generating means 22 comprising a U-shaped yoke 17, for surrounding a sound magnetic circuit section 16 configuring a dynamic speaker, on which an electromagnetic coil 18 is wound; and a weight 19 supported by support springs 20A, 20B fitted to magnets 21A, 21B standing face to face with tips of the U-shaped yoke 17, is arranged in a single enclosure 12 and the weight is configured to be vibrated in a horizontal direction different from the thickness direction of the enclosure 12.
