The invention relates to the technical field of vibrating motors, and more particularly relates to a coreless cylindrical vibrating motor which is arranged in a portable electronic device such as a
mobile phone, a personal digital assistant (PDA) and the like and causes vibration when necessary. A rotor comprises a coil, first and second vibration sources and a
commutator, wherein the coil is accommodated in a
stator; the first and second vibration sources are separated from each other by a
magnet and arranged oppositely, a center shaft is inserted in the first and second vibration sources, and the first and second vibration sources induce vibration when rotating eccentrically from the center shaft; and the
commutator is fixed on the second
vibration source and is run through by the center shaft. The rotor is arranged in a rotation space in a shell and can rotate; an electric
brush is supported on an electric
brush terminal, and is in electrical contact with a conductor
commutator segment of the commutator; the electric
brush terminal is pressed into one end which is fixed on the upper part of the
open shell and is used for accommodating the center shaft for fixed supporting; and a vibrator is arranged in the shell but not outside the shell, so the length of the shell and the length of the coil arranged in the shell can be prolonged, and then low
current consumption can be embodied, and the abrasion between the commutator and the electric brush can be reduced. Besides, the two vibration sources are combined with rotation in the coil, so the response speed can be improved, and high vibration force can be generated. The coreless cylindrical vibrating motor has the advantages of low
current consumption, quick response, long service life, high vibrating force and the like.
