如第3圖所示,環型底座330之厚度沿環型方向CD1從位置LA朝向位置LH逐漸減少。如第2圖所示,第2圖之右側對應於位置LB,環型底座330具有厚度T2;第2圖之左側對應於位置LF,環型底
座330具有厚度T5。厚度T5小於厚度T2。相對的,如第2圖所示,第2圖之右側對應於位置LB,環型底座330與上蓋350間隔一間距D2;第2圖之左側對應於位置LF,環型底座330與上蓋350間隔一間距D5。間距D5大於間距D2。

如第3圖所示,第一環型電極310與第二環型電極320以同心圓之方式設置於環型底座330(繪示於第2圖)上。如第2圖所示,壓電材料340至少設置於第一環型電極310及第二環型電極320之間。在本實施例中,壓電材料340覆蓋第一環型電極310及第二環型電極320。壓電材料340未被推抵時,壓電材料340之厚度在各個位置均為一致。

如第2圖所示,推抵元件360轉動至位置LF時,環型底座330與上蓋350間隔較大的間距D5,故彈性件363的壓縮程度較小,而使平板361給予壓電材料340較小的推力F5。

請參照第10圖,其繪示壓電旋鈕300被按壓之示意圖。在一實施例中,轉軸370可以是伸縮結構。使用者可以按壓上蓋350,而將間距D2壓縮為間距D2’,並將間距D5壓縮為間距D5’。間距D5進一步被壓縮為間距D5’時,推抵元件360對壓電材料340的推力F5提升為推力F5’,而更進一步壓縮壓電材料340。
Please refer to FIG. 10 , which shows a schematic diagram of the
請參照第11圖,其繪示根據一實施例之位置LA~LH之電流變化曲線CV4與電流變化曲線CV4’。電流變化曲線CV4對應於上
蓋350未被按壓之情況,電流變化曲線CV4’對應於上蓋350有被按壓之情況。電流變化曲線CV4與電流變化曲線CV4’可透過一電流臨界值TH明顯區分。筆記型電腦1000之處理單元400(繪示於第1圖)可以依據第一環型電極310與第二環型電極320之間的電流,分析出上蓋350是否有被按壓。舉例來說,推抵元件360轉動至位置LF時,若處理單元400分析出電流I5,則判定上蓋350未被按壓;若處理單元400分析出電流I5’,則判定上蓋350有被按壓。
