    • An accessible pedestrian pushbutton station. The station includes an articulating rear mounting structure to facilitate accurate positioning of the station on either a curved or flat surface. Additionally, slots in the rear mounting structure allow for minor positional adjustments during installation. The crossing direction arrow is easily repositioned on the front of the station without disassembling the housing. After removing the screw-mounted arrow, the plunger can be turned clockwise or counter-clockwise using only a flat-head screw driver. The plunger is balanced between oppositely biased springs. The spring-balanced plunger indirectly actuates an offset piezo bender using a flexible spring actuator and a second, offset stem bumper. This protects the piezo bender from direct pressure and potential damage. The station includes an internal speaker and the housing includes bilateral sound vents to project the sound emitted by the speaker. Baffles may be inserted in one or both of the sound vents.
    • 一个无障碍的行人按钮站。 该车站包括一个铰接的后安装结构,以便于车站在弯曲或平坦表面上的精确定位。 此外,后安装结构中的槽允许在安装期间进行微小的位置调整。 交叉方向箭头很容易重新定位在车站的前方,而不拆卸外壳。 拆下螺钉安装的箭头后,只能使用平头螺丝刀将柱塞顺时针或逆时针转动。 柱塞在相对偏置的弹簧之间平衡。 弹簧平衡柱塞使用柔性弹簧致动器和第二偏置杆保险杠间接地驱动偏移压电弯曲机。 这样可以保护压电弯管机免受直接的压力和潜在的损坏。 该车站包括一个内置扬声器,并且该房屋包括双边通风口,用于投影扬声器发出的声音。 挡板可插入一个或两个声孔。
