The vibrating motor includes a shell providing a receiving cavity, a vibrating unit received in the receiving cavity, a pair of elastic members for elastically suspending two opposite ends of the vibrating unit to the shell, and a linking module. The linking module includes a pair of linking units rotably engaged with the two opposite ends of the vibrating unit respectively. Each of the linking units includes a linking rod and a guiding pin fixed to the shell. An end of the linking rod is engaged with the guiding pin, and the other end of the linking pod is engaged with a corresponding end of the vibrating unit. ## Claims ### Claim 1 A vibrating motor, comprising: a shell providing a receiving cavity; a vibrating unit received in the receiving cavity; a pair of elastic members for elastically suspending the vibrating unit in the receiving cavity; and a linking module comprising a pair of linking units rotably engaged with two opposite ends of the vibrating unit respectively; wherein each of the linking units comprises a linking rod and a guiding pin fixed to the shell; an end of the linking rod is engaged with the guiding pin, and the other end of the linking rod is engaged with a corresponding end of the vibrating unit. ### Claim 2 (depends on 1) The vibrating motor of claim 1, wherein the linking rod comprises a first rod body and a second rod body, the second rod body covers and is attached on the first rod body. ### Claim 3 (depends on 2) The vibrating motor of claim 2, wherein the first rod body comprises a first end with a first through hole, and a second end with a second through hole; the guiding pin passes through the first through hole of the first rod body, and the second through hole is engaged with a corresponding end of the vibrating unit. ### Claim 4 (depends on 3) The vibrating motor of claim 3, wherein each of the linking unit further comprises a first bearing unit surrounding the guiding pin and received in the first through hole. ### Claim 5 (depends on 3) The vibrating motor of claim 3, wherein the vibrating unit comprises a pair of mass members and a magnetic module arranged between the pair of mass members, each of the mass members includes a connection part extending from an end of the mass member and towards a corresponding one of the linking unit. ### Claim 6 (depends on 5) The vibrating motor of claim 5, wherein the connection part of the mass member comprises a pair of connecting arms parallel to each other, and a connecting pillar perpendicular to and connected between the connecting arms, the connecting pillar passes through the second through hole of the first rod body. ### Claim 7 (depends on 6) The vibrating motor of claim 6, wherein each of the linking units further comprises a second bearing member surrounding the connecting pillar and received in the second through hole. ### Claim 8 (depends on 6) The vibrating motor of claim 6, wherein the second rod body comprises a third through hole and a fourth through hole aligned with the first through hole and the second through hole of the first rod body respectively, the guiding pin and the connecting pillar also pass through the third through hole and the fourth through hole respectively. ### Claim 9 (depends on 5) The vibrating motor of claim 5, wherein the connection part of one of the mass members is diagonally arranged to the connection part of the other one of the mass members in the vibrating unit, and symmetrical to each other about a central point of the vibrating unit. ### Claim 10 (depends on 6) The vibrating motor of claim 6, wherein each of the elastic members is a U-shaped elastic member. ### Claim 11 (depends on 10) The vibrating motor of claim 10, wherein the elastic member comprises an elastic arm passing through a gap between the pair of the connecting arms of a corresponding mass member. ### Claim 12 (depends on 11) The vibrating motor of claim 11, wherein the elastic member further comprises two extending parts extending from two opposite ends of the elastic arm; the two extending parts are respectively connected to the shell and the corresponding mass member. ### Claim 13 (depends on 5) The vibrating motor of claim 5, wherein the magnetic module comprises a pair of magnets and a yoke arranged between the pair of magnets. ### Claim 14 (depends on 1) The vibrating motor of claim 1, wherein the shell comprises a main housing and a top plate covering the main housing for forming the receiving cavity, the main housing comprises a bottom plate opposite to the top plate, and the guiding pin is fixed to the bottom plate. ### Claim 15 (depends on 13) The vibrating motor of claim 13, wherein the guiding pin of one of the linking units is diagonally arranged to the guiding pin of the other one of the linking units in the main housing. ### Claim 16 (depends on 13) The vibrating motor of claim 13, further comprising a coil for driving the vibrating unit to vibrate, the coil is fixed to the bottom plate of the shell. ### Claim 17 (depends on 13) The vibrating motor of claim 13, wherein the linking module is configured for restricting the vibrating unit to vibrate in a vibrating plane parallel to the bottom plate.
