Problems solved by technology

[0009] However, as shown in FIG. 1, in the conventional coin type vibration motor, since the counterweight 113 is positioned on the upper part of the rotor, the size of the coil 107 cannot be increased, and thus the vibration of the motor cannot be enhanced.
In addition, since the magnet 108 is mounted only on the bracket 109, the number of flux lines passing through the coil 107 cannot be large enough, so that the vibration of the motor cannot be enhanced.

Abstract

The invention discloses a libration motor comprising a base seat and a shell forming an inner space; an axes rotatablely inserted in the base seat and the shell; a rotor inserted in the axes and comfigured rotatable, and including a plurality of windings and a commutator connected to the windings; a balance weight mounted on a lower surface of the rotor; an electric brush contacted with the commutator and positioned on the base seat; and a magnet faced to the rotor. The libration motor is capable of enhancing libration and reducing electric consumption during operation.

Description

[0001] Related Application Cross Reference [0002] This application claims the benefit of Korean Patent Application No. 2005-0130582 filed with the Korean Intellectual Property Office on December 27, 2005, the entire contents of which are hereby incorporated by reference. technical field [0003] The invention relates to a vibration motor. Background technique [0004] In general, a vibration motor generates vibration when a rotor rotates in an eccentric structure, and such a vibration motor is generally manufactured to have a small size for use in a mobile phone or a pager or the like. [0005] Fig. 1 and Fig. 2 have shown common coin-type vibration motor, and wherein Fig. 1 is the plane view of rotor molding part (mold portion), and this rotor molding part is integrated with the rotor that is arranged on the inner side upper part of vibration motor, and Fig. 2 is a cross-sectional view specifically showing the coin-type vibration motor along the section II' of FIG. 1 . ...
