Looking at the photos now, but suggestion, resize the photos so they fit in one screen
-Where is the piezoelectric (bender)? Is it on the reverse (inner) side of the case back or is that it on the reverse (inner) of the case front; photo 1?
-if on case back please post image of the reverse side of the case back.
-if on the reverse of the case back I cannot see a spring contact to connect to the piezoelectric on the module.
-if on the reverse of the case front I need to see the front (LCD) of the module.
Not familiar with the movement hence the questions.
