The invention relates to a vibrator which comprises permanent magnets, a coil and a hollow cylinder body, wherein, the permanent magnets are one pair, the two permanent magnets are respectively fixed on two sides of a magnetic conductive sheet, the ends with the same polarity of the two permanent magnets are opposite, the two permanent magnets and the magnetic conductive sheet are positioned in a cavity of the cylinder body, a magnetic conductive ring is sheathed at the middle part of the surface of the cylinder body, the coil is divided into two parts and wound on the surface of the cylinder body which is positioned on two sides of the magnetic conductive ring, a housing is sheathed outside the cylinder body, and two ends of the coil are introduced out of the housing. The housings are two and connection plates similar to ''L'' shape is fixed on the bottoms of the housings. The connection plates on the two housings are engaged and matched with each other. Connection points arranged between two parts of the coils at the two sides of the magnetic conductive ring and two ends of the whole coil are arranged on the connection plates. The two ends of the coil are respectively connected to conductive lines through out of the housings. The vibrator has the advantages of reasonable structure, sensitive vibration, good vibration effect and long service life, and can be widely applied on products like massage devices, sex toys, mobile phones and the like.
