Abstract
Laminated vehicle glass structures included embedded piezoelectric exciters for sound generation. The piezoelectric exciters are embedded at least partially within the laminating materials and are offset relative to a centerline longitudinally extending between the opposing glass panels. Also disclosed are processes for forming the laminated glass structures. The laminated glass structures can be utilized about the vehicle anywhere sound generation is desired, e.g., passenger windows, fixed or sliding roofing systems, front windshield, rear windshield, side windows, rear quarter glasses, and the like. The piezoelectric exciters act as a diaphragm to produce sound upon vibration.
