The laminated vehicle glass structure includes a printed piezoelectric actuator for generating sound. An annular piezoelectric actuator is printed on an inner surface of a selected one of the outer glass panel or the inner glass panel. The printing piezoelectric actuator is offset relative to a centerline extending longitudinally between the opposing glass panels. Methods for forming a laminated glass structure including at least one printed piezoelectric actuator are also disclosed. The laminated glass structure may be used anywhere around the vehicle where sound needs to be generated, such as passenger windows, sunroofs, front windshields, rear windshields, and the like. A printed ring piezoelectric actuator is used as a diaphragm to produce sound upon excitation.
层压车辆玻璃结构包括用于产生声音的打印压电致动器。环形压电致动器打印在外玻璃面板或内玻璃面板中选择的一个的内表面上。打印压电致动器相对于在相对的玻璃面板之间纵向延伸的中心线偏移。还公开了用于形成包括至少一个打印压电致动器的层压玻璃结构的方法。层压玻璃结构可在车辆周围需要产生声音的任何地方使用,例如乘客窗户、天窗、前风挡、后风挡等。打印的环形压电致动器用作膜片以在激励时产生声音。
