請參照第2圖及第3圖，第2圖繪示根據一實施例之壓電旋鈕300沿截面線2-2’之剖面圖，第3圖繪示第2圖之壓電旋鈕300之部分元件的俯視圖。壓電旋鈕300包括一環型底座330、一第一環型電極310、一第二環型電極320、一壓電材料340、一上蓋350、一推抵元件360及一轉軸370。第3圖僅繪示出第一環型電極310、第二環型電極320、壓電材料340及推抵元件360。如第3圖所示，沿一環型方向CD1，壓電旋鈕300可以劃分為位置LA、位置LB、位置LC、位置LD、位置LE、位置LF、位置LG、位置LH。 Please refer to FIG. 2 and FIG. 3. FIG. 2 shows a cross-sectional view of a piezoelectric knob 300 according to an embodiment along the section line 2-2', and FIG. 3 shows a part of the piezoelectric knob 300 in FIG. 2 A top view of the component. The piezoelectric knob 300 includes an annular base 330 , a first annular electrode 310 , a second annular electrode 320 , a piezoelectric material 340 , an upper cover 350 , a pushing element 360 and a rotating shaft 370 . FIG. 3 only shows the first ring electrode 310 , the second ring electrode 320 , the piezoelectric material 340 and the pushing element 360 . As shown in FIG. 3 , along a circular direction CD1 , the piezoelectric knob 300 can be divided into positions LA, LB, LC, LD, LE, LF, LG, and LH.

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。 As shown in FIG. 3 , the thickness of the annular base 330 gradually decreases from the position LA toward the position LH along the annular direction CD1 . As shown in Figure 2, the right side of Figure 2 corresponds to position LB, and the annular base 330 has a thickness T2; the left side of Figure 2 corresponds to position LF, and the annular base 330 has a thickness T2; Seat 330 has a thickness T5. Thickness T5 is smaller than thickness T2. In contrast, as shown in Figure 2, the right side of Figure 2 corresponds to the position LB, and the annular base 330 is spaced from the upper cover 350 by a distance D2; the left side of Figure 2 corresponds to the position LF, and the annular base 330 is spaced from the upper cover 350 A distance D5. The distance D5 is greater than the distance 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。 As shown in FIG. 3 , the first ring-shaped electrode 310 and the second ring-shaped electrode 320 are arranged concentrically on the ring-shaped base 330 (shown in FIG. 2 ). As shown in FIG. 2 , the piezoelectric material 340 is at least disposed between the first ring-shaped electrode 310 and the second ring-shaped electrode 320 . In this embodiment, the piezoelectric material 340 covers the first ring-shaped electrode 310 and the second ring-shaped electrode 320 . When the piezoelectric material 340 is not pushed, the thickness of the piezoelectric material 340 is consistent at each position.

如第2圖所示，上蓋350覆蓋環型底座330。推抵元件360連接上蓋350，並推抵壓電材料340。轉軸370連接上蓋350，以使上蓋350及推抵元件360以轉軸為中心相對環型底座330轉動。 As shown in FIG. 2 , the upper cover 350 covers the annular base 330 . The pushing element 360 is connected to the upper cover 350 and pushes against the piezoelectric material 340 . The rotating shaft 370 is connected to the upper cover 350 so that the upper cover 350 and the pushing element 360 rotate relative to the ring-shaped base 330 around the rotating shaft.

如第2圖所示，推抵元件360包括一平板361、一連桿362及一彈性件363。平板361抵靠壓電材料340。連桿362連接平板361及上蓋350。連桿362係為伸縮結構。彈性件363套接於連桿362，以使平板361緊密抵靠壓電材料340。 As shown in FIG. 2 , the pushing element 360 includes a flat plate 361 , a connecting rod 362 and an elastic member 363 . The flat plate 361 is against the piezoelectric material 340 . The connecting rod 362 connects the plate 361 and the upper cover 350 . The connecting rod 362 is a telescopic structure. The elastic member 363 is sleeved on the connecting rod 362 so that the plate 361 is tightly against the piezoelectric material 340 .

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。 As shown in FIG. 2, when the pushing member 360 rotates to the position LF, the distance D5 between the annular base 330 and the upper cover 350 is relatively large, so the compression degree of the elastic member 363 is relatively small, and the piezoelectric material 340 is imparted to the flat plate 361. Smaller thrust F5.

請參照第4圖及第5圖，第4圖繪示第2圖之壓電旋鈕300之推抵元件360轉動至位置LB之剖面圖，第5圖繪示第3圖之壓電旋鈕300之推抵元件360轉動至位置LB之俯視圖。如第4圖所示，推抵元件 360轉動至位置LB時，環型底座330與上蓋350間隔較小的間距D2，故彈性件363的壓縮程度較大，而使平板361給予壓電材料340較大的推力F2。 Please refer to Fig. 4 and Fig. 5, Fig. 4 shows a cross-sectional view of the push element 360 of the piezoelectric knob 300 in Fig. The top view of the pushing element 360 rotated to the position LB. As shown in Figure 4, the push element When the 360 rotates to the position LB, the distance D2 between the annular base 330 and the upper cover 350 is relatively small, so the compression degree of the elastic member 363 is relatively large, and the plate 361 gives a relatively large thrust F2 to the piezoelectric material 340 .

請參照第6圖及第7圖，第6圖繪示壓電材料340受到較小之推力F5的示意圖，第7圖繪示壓電材料340受到較大之推力F2的示意圖。壓電材料340包括導電粒子341及可撓載板342。如第6圖所示，當壓電材料340受到較小之推力F5時，導電粒子341的排列較為鬆散，故壓電材料340的導電性較差，使得第一環型電極310及第二環型電極320之間形成較小的電流I5。如第7圖所示，當壓電材料340受到較大之推力F2時，導電粒子341的排列較為緊密，故壓電材料340的導電性較佳，使得第一環型電極310及第二環型電極320之間形成較大的電流I2。 Please refer to FIG. 6 and FIG. 7, FIG. 6 shows a schematic diagram of the piezoelectric material 340 receiving a small thrust F5, and FIG. 7 shows a schematic diagram of the piezoelectric material 340 receiving a large thrust F2. The piezoelectric material 340 includes conductive particles 341 and a flexible carrier 342 . As shown in Figure 6, when the piezoelectric material 340 is subjected to a small thrust F5, the arrangement of the conductive particles 341 is relatively loose, so the conductivity of the piezoelectric material 340 is relatively poor, so that the first ring-shaped electrode 310 and the second ring-shaped electrode 310 A small current I5 is formed between the electrodes 320 . As shown in Figure 7, when the piezoelectric material 340 is subjected to a greater thrust F2, the arrangement of the conductive particles 341 is relatively close, so the conductivity of the piezoelectric material 340 is better, so that the first annular electrode 310 and the second annular electrode 310 A large current I2 is formed between the type electrodes 320 .

請參照第8圖，其繪示根據一實施例之位置LA~LH之厚度變化曲線CV1、間距變化曲線CV2、推力變化曲線CV3及電流變化曲線CV4。如厚度變化曲線CV1所示，推抵元件360從位置LA轉動至位置LH時，環型底座330之厚度逐漸減少。如間距變化曲線CV2所示，推抵元件360從位置LA轉動至位置LH時，環型底座330與上蓋350間隔的間距逐漸增加。如推力變化曲線CV3所示，推抵元件360從位置LA轉動至位置LH時，推抵元件360的推力逐漸降低。如電流變化曲線CV4所示，推抵元件360從位置LA轉動至位置LH時，第一環型電極310及第二環型電極320之間的電流逐漸降低。 Please refer to FIG. 8 , which shows the thickness variation curve CV1 , the pitch variation curve CV2 , the thrust variation curve CV3 and the current variation curve CV4 at the positions LA˜LH according to an embodiment. As shown in the thickness variation curve CV1 , when the pushing member 360 rotates from the position LA to the position LH, the thickness of the ring base 330 gradually decreases. As shown by the distance change curve CV2 , when the pushing member 360 rotates from the position LA to the position LH, the distance between the annular base 330 and the upper cover 350 increases gradually. As shown in the thrust variation curve CV3, when the pushing element 360 rotates from the position LA to the position LH, the thrust of the pushing element 360 decreases gradually. As shown by the current change curve CV4 , when the pushing element 360 rotates from the position LA to the position LH, the current between the first ring electrode 310 and the second ring electrode 320 decreases gradually.

根據上述設計，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，分析出壓電旋鈕300之上蓋350之轉動位置。處理單元400例如是一晶片、一電路板、一電路、一電腦程式產品、或儲存程式碼之電腦可讀取記錄媒體。再者，處理單元400可以週期性判斷壓電旋鈕300之上蓋350的轉動位置，並且進一步根據轉動位置的變化分析出轉動方向與轉動速度。 According to the above design, the processing unit 400 (shown in FIG. 1 ) of the notebook computer 1000 can be based on the current between the first ring electrode 310 and the second ring electrode 320, The rotational position of the cover 350 on the piezoelectric knob 300 is analyzed. The processing unit 400 is, for example, a chip, a circuit board, a circuit, a computer program product, or a computer-readable recording medium storing program codes. Furthermore, the processing unit 400 can periodically determine the rotational position of the cover 350 of the piezoelectric knob 300 , and further analyze the rotational direction and rotational speed according to the change of the rotational position.

請參照第9圖，其繪示根據一實施例之壓電旋鈕300之操作方法的流程圖。在步驟S110中，處理單元400偵測第一環型電極310及第二環型電極320之間的電流。 Please refer to FIG. 9 , which shows a flow chart of the operation method of the piezoelectric knob 300 according to an embodiment. In step S110 , the processing unit 400 detects the current between the first ring electrode 310 and the second ring electrode 320 .

接著，在步驟S120中，處理單元400依據第一環型電極310與第二環型電極320之間的電流，分析壓電旋鈕300之轉動位置。 Next, in step S120 , the processing unit 400 analyzes the rotational position of the piezoelectric knob 300 according to the current between the first ring electrode 310 and the second ring electrode 320 .

然後，在步驟S130中，處理單元400依據轉動位置的變化，分析轉動方向與轉動速度。 Then, in step S130 , the processing unit 400 analyzes the rotation direction and the rotation speed according to the change of the rotation position.

接著，在步驟S140中，處理單元400依據轉動位置、轉動方向或轉動速度執行對應的操作動作。 Next, in step S140, the processing unit 400 executes corresponding operation actions according to the rotation position, rotation direction or rotation speed.

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 piezoelectric knob 300 being pressed. In an embodiment, the rotating shaft 370 may be a telescopic structure. The user can press the upper cover 350 to compress the distance D2 into a distance D2', and compress the distance D5 into a distance D5'. When the distance D5 is further compressed to the distance D5', the thrust F5 of the pushing element 360 on the piezoelectric material 340 is increased to the thrust F5', and the piezoelectric material 340 is further compressed.

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。 Please refer to FIG. 11, which shows the current change curve CV4 and the current change curve CV4' of the positions LA~LH according to an embodiment. The current change curve CV4 corresponds to the upper When the cover 350 is not pressed, the current change curve CV4' corresponds to the case where the upper cover 350 is pressed. The current variation curve CV4 and the current variation curve CV4' can be clearly distinguished by a current threshold value TH. The processing unit 400 (shown in FIG. 1 ) of the notebook computer 1000 can analyze whether the upper cover 350 is pressed according to the current between the first ring electrode 310 and the second ring electrode 320 . For example, when the pushing element 360 rotates to the position LF, if the processing unit 400 analyzes the current I5, then it is determined that the upper cover 350 is not pressed; if the processing unit 400 analyzes the current I5', then it is determined that the upper cover 350 is pressed.
