Apparatus for providing haptic feedback
View Patent ↗Disclosed is an apparatus used in an electronic device for providing haptic feedback. The apparatus includes a holder having a pair fastening holes, a piezoelectric vibrator having a first though holes, a terminal with a second though hole mounted on the piezoelectric vibrator and electrically connected to the piezoelectric vibrator, and a pair of fixing portions fixing the terminal and the piezoelectric vibrator on the holder though the second though hole of the terminal, a first though holes of the piezoelectric vibrator and the fastening holes of the holder. The fixing portions fix the terminal and piezoelectric vibrator on the holder, which makes the assembling process much easier.
1. An apparatus for proving haptic feedback, comprising:
a holder having a pair of mounting portions, each of the mounting portions comprising at least a fastening hole;
a piezoelectric vibrator having a substrate, a first piezoelectric layer attached to a side of the substrate for being elastically supported by the substrate, the substrate having a main body and a pair of fastening portions extending from two ends of the main body and mounted on the mounting portions of the holder, each of fastening portion comprising at least a first though hole;
a terminal with a fixing plate mounted on one fastening portion and electrically connected to the piezoelectric vibrator, the fixing plate comprising a second though hole; and
a pair of fixing portions fixing the terminal and the piezoelectric vibrator on the mounting portion though the second though hole of the fixing plate, a first though holes of fastening portions and the fastening holes of the mounting portions.
2. The apparatus for providing haptic feedback as described in claim 1 , wherein the holder comprises a plastic base and a metal plate assembled with the plastic base by injection molding for improving the mechanical strength of the apparatus, the mounting portions is formed on the plastic base.
3. The apparatus for providing haptic feedback as described in claim 2 , wherein the metal plate comprises a main plate and a plurality of stops extending perpendicular from the main plate and parallel to the fastening portion of the piezoelectric vibrator for limiting the vibrating amplitude of the piezoelectric vibrator.
4. The apparatus for providing haptic feedback as described in claim 2 , wherein each mounting portion comprises a step portion for supporting the piezoelectric vibrator.
5. The apparatus for providing haptic feedback as described in claim 4 , wherein each mounting portion further comprise a first sidewall extending from the step portion and perpendicular to the step portion, and a second sidewall extending from the step portion and respectively perpendicular to the step portion and the first side wall, and the terminal further comprises an engaging plate extending perpendicular from another end of the fixing plate for firmly engaging with the holder.
6. The apparatus for providing haptic feedback as described in claim 1 , wherein the fixing portions comprise screws.
7. The apparatus for providing haptic feedback as described in claim 1 , wherein the fixing portions comprise rivets.
8. The apparatus for providing haptic feedback as described in claim 1 further comprising a pair of spacers each having a third though hole and sandwiched between the fixing portions and the terminal for protecting the terminal from scratch by the fixing portions.
9. The apparatus for providing haptic feedback as described in claim 8 , wherein the terminal further comprises a U-shaped plate extending from one end of the fixing plate for clamping with the piezoelectric vibrator.
