Apparatus for providing haptic feedback
View Patent ↗Disclosed is an apparatus for providing haptic feedback. The apparatus includes a frame having a protrusion extending from the side wall of the frame, a piezoelectricity vibrator including a substrate having a main body, at least one piezoelectric layer attached to the main body of the substrate, the main body defining two contact portions extending out of the side facing to the frame, and the two contact portions clip the protrusion for fixing together. The apparatus includes a first through hole arranged on the protrusion and two second through holes respectively arranged on the two contact portions and corresponding to the first through hole, and a screw passing through the second through holes and the first through hole for engaging the contact portions with protrusion together.
1. An apparatus for proving haptic feedback, comprising:
a base;
a frame mounted on the base with a ring body and a protrusion extending outwardly from the ring body;
a piezoelectric vibrator fixed on the base, including a substrate with a main body and at least one piezoelectric layer attached to the substrate;
a clip portion extending out of the substrate and toward the frame for connecting with the protrusion of the frame.
2. The apparatus for providing haptic feedback as described in claim 1 , wherein the clip portion includes a pair of contacting pieces respectively extending from two opposite edges of the main body of the substrate for clipping the protrusion.
3. The apparatus for providing haptic feedback as described in claim 2 further including a first through hole in the protrusion, two second through holes in the contacting pieces corresponding to the first through hole, and a first fixing portion passing through the first through hole and the two second through holes and corresponding to the two second through holes for fixing the clip portion on the protrusion firmly.
4. The apparatus for providing haptic feedback as described in claim 3 , wherein the pair of contacting pieces is perpendicular to the main body of the substrate.
5. The apparatus for providing haptic feedback as described in claim 4 , wherein the pair of contacting pieces locates in the middle edge of the main body of the substrate.
6. The apparatus for providing haptic feedback as described in claim 5 , wherein the pair of contacting pieces opposite to each other.
7. The apparatus for providing haptic feedback as described in claim 1 , wherein the base further includes a pair of steps for supporting the piezoelectricity vibrator.
8. The apparatus for providing haptic feedback as described in claim 7 , wherein the base has a main surface having an accommodation space for receiving the piezoelectric vibrator, and the piezoelectric vibrator is partially suspended in the accommodation space.
9. An apparatus for proving haptic feedback, comprising:
a base;
a frame connecting to the base and having a side wall, and a protrusion extending out of the side wall;
a piezoelectric vibrator fixed on the base, including a substrate having a main body with two opposite sides, a first piezoelectric layer attached to one side of the main body of the substrate; wherein
the main body has two contacting pieces extending out of the side facing to the frame, and the two contacting pieces clip the protrusion for fixing together.
10. The apparatus for providing haptic feedback as described in claim 9 further including a first through hole arranged on the protrusion and two second through holes respectively arranged on the two contacting pieces and corresponding to the first through hole, and a screw passing through the first through hole and the second through holes for cooperating contacting pieces and protrusion together.
11. The apparatus for providing haptic feedback as described in claim 10 , wherein the two contacting pieces extend out from the two opposite edges of the side facing to the frame.
12. The apparatus for providing haptic feedback as described in claim 11 , wherein the two contacting pieces are vertical to the main body of the substrate.
13. The apparatus for providing haptic feedback as described in claim 12 , wherein the two contacting pieces are opposed from each other.
14. The apparatus for providing haptic feedback as described in claim 9 further comprising a second piezoelectric layer attached to another side of the main body of the substrate.
15. The apparatus for providing haptic feedback as described in claim 9 , wherein the base further includes a pair of steps for supporting the piezoelectricity vibrator.
16. An apparatus for providing haptic feedback, comprising:
a frame having a protrusion with a first through hole therein;
a piezoelectric vibrator including a substrate having a main body and at least one piezoelectric layer attached to the main body of the substrate;
a pair of contacting pieces with second through holes extending from the two opposite edges of the main body of the substrate and facing to the protrusion;
a first screw arranged to pass through the first through hole and second through holes for fixing the pair of contacting pieces and the protrusion firmly.
17. The apparatus for providing haptic feedback as described in claim 16 , wherein the protrusion locates between the pair of the contacting pieces.
18. The apparatus for providing haptic feedback as described in claim 16 , wherein the protrusion is parallel to the contacting pieces.
19. The apparatus for providing haptic feedback as described in claim 16 , wherein the pair of contacting pieces is vertical to the main body of the substrate.
