the second mass member includes a groove or a protrusion corresponding to the protrusion or the groove of the first mass member.
10. The haptic feedback device of claim 7 , wherein the second mass member is an adhesive having a predetermined mass, and
the first mass member includes a receiving space for the adhesive.
11. A haptic feedback device, comprising:
a vibrating member; and
a vibrating element formed on the vibrating member to vibrate the vibrating member,
wherein the vibrating member has a structure in which a plurality of vibrating plates are connected in parallel in a width direction of the vibrating member.
12. The haptic feedback device of claim 11 , wherein the vibrating member is divided into the plurality of vibrating plates by a separating groove extending in a length direction of the vibrating member.
13. The haptic feedback device of claim 11 , wherein the plurality of vibrating plates are provided with a plurality of holes in a length direction thereof.
14. The haptic feedback device of claim 11 , wherein the plurality of vibrating plates are integrally formed with the vibrating member by a pressing process.
15. The haptic feedback device of claim 11 , further comprising a first mass member provided to the vibrating member.
16. The haptic feedback device of claim 15 , further comprising a second mass member having a predetermined mass,
wherein the second mass member is an adhesive so as to be bonded to the first mass member.
17. The haptic feedback device of claim 15 , wherein the first mass member has a coupling structure so as to be coupled to the second mass member.
18. The haptic feedback device of claim 17 , wherein the first mass member includes an insertion hole into which the second mass member is inserted.
19. The haptic feedback device of claim 17 , wherein the first mass member includes a protrusion or a groove so as to be coupled to the second mass member, and
the second mass member includes a groove or a protrusion corresponding to the protrusion or the groove of the first mass member.
20. A haptic feedback device, comprising:
a vibrating member;
a vibrating element formed on the vibrating member to vibrate the vibrating member;
a first mass member provided to the vibrating member; and
a second mass member selectively coupled to the first mass member.
21. The haptic feedback device of claim 20 , wherein the first mass member includes an insertion hole into which the second mass member is inserted.
22. The haptic feedback device of claim 20 , wherein the first mass member includes a protrusion or a groove so as to be coupled to the second mass member, and
the second mass member includes a groove or a protrusion corresponding to the protrusion or the groove of the first mass member.
23. The haptic feedback device of claim 20 , wherein the vibrating member includes:
a first plate member elongated in a first direction; and
a pair of second plate members extended from both sides of the first plate member and bent in a second direction perpendicular to the first direction so as to be coupled to the first mass member.
24. The haptic feedback device of claim 20 , further comprising an upper case and a lower case receiving the first mass member and the vibrating member.
25. The haptic feedback device of claim 24 , wherein the upper case includes a receiving groove.
26. The haptic feedback device of claim 25 , wherein the second mass member having a predetermined mass and being curable at room temperature is provided in the first mass member through the receiving groove.
27. A haptic feedback device, comprising:
a vibrating member coupled to a fixed body while having a first vibrating length due to a first fixed point;
a vibrating element formed on the vibrating member to vibrate the vibrating member; and
at least one second fixed point at which the vibrating member is coupled to the fixed body while having a second vibrating length different from the first vibrating length.
