A vibrator is disposed in an electro-acoustic transducer and includes a central portion, an edge portion, a combining portion and a reinforcement structure. The edge portion surrounds at out periphery of the central portion, the combing part surrounds at outer periphery of the edge portion and is combined with the electro-acoustic transducer, whereas the reinforcement structure is attached to the central portion and is provided with a corrugated sheet. Between every two peaks and between every two troughs of the corrugated sheet are filled with a foaming material, allowing the vibrator to have a better stiffness and damping, so as to improve an acoustics performance of the electro-acoustic transducer.
