Embodiment Construction

[0080] As shown in FIG. 3 , the bar type vibration motor 1 according to the present invention includes a stator unit 10 , a rotor unit 30 and a power supply unit 50 , wherein the stator unit 10 is described first.

[0081] The stator unit 10 includes a body 12 and a magnet 14, and the body 12 is a hollow cylinder integrally formed with a hollow support tube 12a located therein.

[0082] In other words, as shown in FIG. 4 , the body 12 has a double pipe structure, wherein the support pipe 12 a is connected to one end of the body 12 and is located in the body 12 .

[0083] In this case, a bearing insertion tube 12b is formed in the body 12 at the front end of the support tube 12a.

[0084] The bearing insertion pipe 12b is formed by the first outer wall 12c.

[0085] A first outer wall 12c protrudes from one end of the body 12 to the outside, and a bearing insertion pipe 12b is formed in the first outer wall 12c.

[0086] The bearing insertion tube 12b protrudes outward and ex...

Abstract

A bar-type vibration motor is comprised of a stator unit including a body and a magnet attached in the body; a rotor unit including a rotary shaft having one end fixed to an eccentric weight and the other end fixed to a stationary member, a portion of the rotary shaft adjacent to the eccentric weight being rotatably supported by the body like a cantilever, a commutator having several segments attached on one side of the stationary member, and an armature fixed to the stationary member spaced apart from the magnet, and electrically connected with the commutator; and a power supply unit including a fixing cap fixed to the body and a brush mounted on the fixing cap to supply voltage to the armature.

Description

[0001] priority [0002] This application claims priority to Korean Patent Application No. 2004-470 filed in the Korean Intellectual Property Office on Jan. 6, 2004, the contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a vibrating motor for generating vibration by rotating an eccentric weight, and more particularly, to a vibration motor that can be compacted by improving the supporting structure of the rotating shaft, the coupling structure of the fixed member, and the connecting structure of the commutator and the brush. Customized bar type vibrating motor. Background technique [0004] As a portable communication device commonly used at present, a mobile phone has various signal generators to transmit various signals to users. [0005] In other words, when a message or call is received, the signal generator generates sound, light or vibration so that the user can know the incoming message or call. [0006] ...
