摘要：
A touch panel device, includes a transparent protective substrate disposed on a front side of the touch panel, the protective substrate being configured by joining a first glass substrate residing on a front side and a second glass substrate residing on a touch panel side, wherein either one of the first and second glass substrates is configured to have one or more stepped portions formed either on a rear surface of the first glass substrate or a front surface of the second glass substrate, the rear surface of the first glass substrate and the front surface of the second glass substrate facing one another; and one or more piezo vibration elements each disposed within one of the stepped portions so as to be acoustically coupled with the first glass substrate, wherein each of said one or more stepped portions is configured thicker than the corresponding piezo vibration element.
