200934065 九、發明說明： 【發明所屬之技術領域】 本發明係有關振動型電磁發電機，例如，在以複數個 - 電磁線圈所構成之發電線圈中，藉由於長度方向被磁化之 % 至少一個磁鐵的振動而進行發電。 【先前技術】 近年來，由於手機及遊樂機等之攜帶電子機器的普及 0 進展，內裝在該等的2次電池的量逐漸增多。又，隨著無 線技術的發展，由微小電力收送信號之 RFID(Radio Frequency IDentification)的應用漸廣泛。尤其具有電源之 有源RFID，也可通信數百公尺以i。因此，牧場之牛、馬 等的健康管理，和學童上下學時之安全管理等的應用被賦 予高度期待。 . 另一方面，爲了地球環境的維持改善，盡可能環境負 ^ 擔少的電池也活躍地被進行硏究開發。其中，將通常無意 〇 識且浪費地被消費之能量轉換成電能、充電、再利用此電 能作爲攜帶機器等的電源被廣泛地思考著。 在專利文獻1，揭示有關透過從外部加以振動而發電 的振動型電磁發電機。在此，參照第11圖說明關於振動型 電磁發電機100的構成例。振動型電磁發電機100,係具備 由非磁性材料所形成之管102,與被收納在管102而於長度 方向磁化之棒狀的可動磁鐵101。在管102的中央部，形成 發電線圈103。在管102的兩端部’以與可動磁鐵101之極 性相同的極性成對向的狀態’設置有磁鐵104a、104b。因 200934065 此’可動磁鐵101振動時，防止可動磁鐵101與管102 兩端部接觸。 在專利文獻2，揭示有關於透過從外部加以振動而 — 電’用所得到之電力發光之備有振動型電磁發電機的手 ^ 筒。在此，參照第12圖說明關於手電筒no的構成例。 電筒110，係具備：由非磁性材料所形成之管112;與被 納在管112並於長度方向磁化之棒狀的可動磁鐵111。在 Φ 112的兩端部，設置有壓縮彈簧114a、114b。藉由此壓 彈簧114a、114b之作用，防止可動磁鐵111與管112的 端部接觸。在管112的中央部形成電磁線圈113。管1 的內部透過可動磁鐵111的振動，由電磁線圈113產生 壓，使LED115發光。透過此發光，LED115發光之光線 係由透鏡1 1 6擴散，而照射於對象物。 , 專利文獻1 :日本專利特開2002 - 28 1 727號公報 專利文獻2:美國專利第5975714號說明書 Q 【發明内容】 可是，在專利文獻1所揭示之技術，則除了對發電 接有用之磁鐵外尙需要配置2個磁鐵在管的兩端部。此 電磁發電機，一般被要求盡可能以小的尺寸狀態，獲得 的發電電力。因此，有需要高的磁通密度。如此，則磁 之成本占整體成本的比率較高。所以，以往的振動型電 發電機100,在成本方面係處於較不利。又，由於多用磁 而使振動型電磁發電機的重量增加，例如，有藉由手操 進行發電時疲勞變大的問題。 的 發 電 手 收 管 縮 兩 12 電 直 種 大 鐵 磁 鐵 作 200934065 又，由於磁鐵之彈回力係不同於藉由彈簧之彈回力， 彈回力並不與可動磁鐵的移動距離成比例。因此，會顯示 與藉由可動磁鐵的質量與螺旋彈簧的彈簧常數所決定的共 . 振振動會有相異的舉動，也會產生可動磁鐵之振動不能長 時間持續的問題。結果，藉由磁鐵之彈回力無法有效地轉 換成振動運動，並不具有可以提高發電力的作用。 又，在專利文獻2所揭示之技術，若於手電筒110施 ❹ 加振動時，可動磁鐵111會暫時從螺旋彈簧離開或衝碰。 因此，可動磁鐵與螺旋彈簧，無法建構成穩定的共振系， 無法提高發電效率。又，因爲可動磁鐵與螺旋彈簧衝碰之 際°會發生衝碰聲音，所以對使用者會形成刺耳。再者，一 般此種發電機，當可動磁鐵通過發電線圈時之速度，有助 於發電（輸出電壓）的大小。由此，爲了獲得更多的發電 . 有必要給與更激烈的振動，所以可動磁鐵與螺旋彈簧透過 激烈的衝突使螺旋彈簧容易破損。 ο 本發明係有鑒於此狀况而著手者，以提供建構成穩定 之共振系同時使螺旋彈簧不易破損之振動型電磁發電機爲 目的。 本發明之振動型電磁發電機，其具備：以非磁性材料 所形成之中空管；被捲繞在管的周圍之至少1個發電線圈 ;至少由1個磁鐵所形成而被配置在管內的可動磁鐵；被 固定在管的至少一端，並將可動磁鐵可振動地支撐在發電 線圈之捲軸方向而可伸縮的彈性體；限制可動磁鐵之振動 的停止器。停止器被形成在管之至少一端，而停止器與可 200934065 動磁鐵接觸的位置，若以管之端部爲起點時，係位於比彈 性體收縮最大時之長度更長的位置。 透過此種構成’使用彈性體構成穩定之共振系的狀態 下，對收縮最大的彈性體不會附加不要的應力。因此，可 獲得即使長期使用彈性體也不會破損且可發生穩定的共振 振動之振動型電磁發電機。 根據本發明時，透過用彈性體支撐可動磁鐵，而可獲 得建構成穩定的共振系之振動型電磁發電機。又，可動磁 鐵超越既定的振幅而振動時，因爲可動磁鐵的振動會受到 停止器的限制，彈性體不會施加多餘的應力，而可防止彈 性體的破損。因此，對於振動型電磁發電機’，可抑制維修 的頻率，而且振動型電磁發電機可經過長期具有發電的效 果。又，作爲彈性體因可使用螺旋彈簧，可降低構件成本 ，同時可實現振動型電磁發電機之輕量化。 【實施方式】 【發明之最佳實施形態】 以下，參照第1圖至第6圖說明有關本發明之第1實 施形態。在本實施之形態例，係適用有關將長度方向磁化 之複數個圓筒形的磁鐵，於複數個電磁線圈中振動或移動 而發電之振動型電磁發電機1爲例加以說明。 首先，參照第1圖之截面圖說明有關本例之振動型電 磁發電機1的構成例。振動型電磁發電機1係由：可動磁 鐵3;與3個電磁線圈（第1電磁線圈4&~第3電磁線圈4c )所構成。3個電磁線圈，係捲附在中空管2之外周所構 200934065 ，於 成。 慮加 配置 磁線 、反 線圈 構成 鐵（ 度方 的磁 反10 構成 之磁 張力 一方 磁鐵 簧5b 依掛 成。透過可動磁鐵3在管2的內部直線往復運動/振動 3個電磁線圈會產生電壓。管2係由非磁性材料所形 管2的材質雖亦可爲金屬等的非磁性體材料，但若考 工性等則以塑膠等的合成樹脂製造較佳。 相隣之3個電磁線圈，係隔著既定的間隔狀態而 ，由極性相反之複數個電磁線圈串列連接所構成。電 圈的捲繞方向，係將各相隣之電磁線圈相互反向的正 、正方向。在以下的說明，係將串列連接之第1電磁 4&~第3電磁線圈4c，稱爲發電線圈9。在管2至少建 1個發電線圈9。 可動磁鐵3，係由同極侄對向而接合之複數個磁 例如，钕磁鐵）所構成。本例之可動磁鐵3，係將長 向磁化之相同長度的2個磁鐵3a、3b，隔著既定厚度 鐵隔板10之後，把同極性相向接合成一體。磁鐵隔1 的材質，係磁性體及非磁性體中任一個均可。又，建 可動磁鐵3之磁鐵至少1個即可。 在可動磁鐵3之一方的端部，被形成保護磁鐵3a 鐵端部構件8 a。在磁鐵端部構件8 a鑽有細孔用以安裝 彈簧之第1螺旋彈簧5a»同樣地，在可動磁鐵3之另 的端部，形成有磁鐵端部構件8b用以保護磁鐵3b。在 端部構件8b鑽有細孔用以安裝張力彈簧之第2螺旋彈 。但，亦可把磁鐵端部構件8a、8b作成鈎等的形狀， 上第1螺旋彈簧5a與第2螺旋彈簧5b的方式而安裝。 如此，在振動型電磁發電機1，透過第1螺旋彈簧5a 200934065 與第2螺旋彈簧5b將可動磁鐵3朝發電線圈9的捲軸方向 振動地支撐。 在管2的兩端部嵌上由樹脂等所形成的第1端構件7a 與第2端構件7b，用以防止可動磁鐵3的飛出。第1端構 件7a與第2端構件7b的形狀相同，分別形成固定部用以 固定第1螺旋彈簧5a與第2螺旋彈簧5b的端部。但，亦 可於第1端構件7a與第2端構件7b形成細孔或掛鈎等， 固定第1螺旋彈簧5a與第2螺旋彈簧5b的端部。 有關本發明之振動型電磁發電機1，如上述，相隣之3 個電磁線圈，隔離既定的間隔之狀態下串列連接，同時其 捲繞方向係各^目隣之電磁線圈相互反向之正、反、正方向 所構成。因此，各個電磁線圈所發生之電壓成爲相位合成 的狀態，藉由合成可使輸出電壓增大。爲此，有必要使磁 鐵長度加上磁鐵間隔片的厚度之磁鐵間距，與線圈長加上 線圈間隔之線圈間距大致相等。再者，使電磁線圈的線圈 長度短於磁鐵長度更佳。 第1螺旋彈簧5a與第2螺旋彈簧5b，係同樣彈簧常數 ，同樣自然長度的螺旋彈簧。但，依規格亦可改變各螺旋 彈簧之彈簧常數與自然長度。 在本實施形態之振動型電磁發電機1，係第1螺旋彈 簧5a與第2螺旋彈簧5b的各個成爲拉著可動磁鐵3的狀 態建構成振動系統。此時，若在振動型電磁發電機1施加 外力時，可動磁鐵3係由可動磁鐵3的質量，與第1螺旋 彈簧5a與第2螺旋彈簧5b的彈簧常數所決定的共振頻率 -10 - 200934065 fr來振動。結果’可動磁鐵3的振動時間變長’可獲得長 時間之電壓。 其次，參照第2A、2B圖說明關於緩和可動磁鐵對管2 . 之端部衝擊的停止器之構成例。在第2A、2B圖雖對第1 停止器6a予以說明’但第2停止器6b也是同樣的構成》 第2A圖係第1螺旋彈簧5a之伸長狀態圖。 第2B圖係第1螺旋彈簧5a縮最短之狀態圖。 ^ 而且，將第1停止器6a與可動磁鐵3接觸之部位的寬 度11，較垂直於發電線圈9之捲軸方向之可動磁鐵3的截 面徑12小。即，螺旋彈簧在伸縮運動時使停止器不會干涉 的方式，且因爲停止器形成與可動磁鐵3可確實地接觸， 超越既定的振幅而振動之可動磁鐵3，係在第1停止器6a 與可動磁鐵3接觸的位置時其振動會受到限制。 . 如第2A圖與第2B圖所示，以第1端構件7a爲起點之 第1停止器6a的高度l〇a，設定比收縮最大的狀態之第1 φ 螺旋彈簧5a的高度l〇b更高。而且，可動磁鐵具有超越既 定振幅之運動能的狀態振動時，在第1停止器6a的上端成 爲接觸/衝突。因此，透過第1停止器6a振幅會受到限制 。再者，第1停止器6a因爲由具有彈性之橡膠等的樹脂所 形成，所以亦可能緩和可動磁鐵3的衝擊。因此，儘管第 1螺旋彈簧5a爲收縮最大的狀態，可有效地抑制可動磁鐵 3會衝突而施加過剩的應力時發生之螺旋彈簧的破損。 在此，第1及/或第2的端構件7a、7b與停止器6a透 過一體成型而形成的情況時，期望選定硬質且具有彈性的 -11- 200934065 橡膠及樹脂。欲選定如此材質，係爲了將振動的可 3確實地密封於管2的內部。又，因爲可動磁鐵3衝 止器6a時對螺旋彈簧不會損傷，且可避免停止器本 傷。 在此’參照第3圖至第6圖說明有關本發明之 電磁發電機1的振動特性。 第3圖係將質量Μ的墜子15與彈簧常數k的螺 16組合所構成的振動系之示意圖。墜子15懸吊在螺 16時，螺旋彈簧16的恢復力，與賦予墜子15之重 衡位置時墜子15即會靜止。此位置設爲零變位。E 若加上外力時，墜子15開始單振動。此振動系統的 率可以次式（1)表示。 【第1式】 fn = (l/2 π )(k/M)..........(1) 可是，在第3圖並未顯示由於摩擦等的振動損 ，在現實之振動系統存在著包含空氣的黏性阻力之 力，及振動體本身之內部摩擦等的各種損失。因此 時間的經過振幅會減振，共振頻率也會稍爲降低。 第4A、4B圖，係對第3圖所顯示之振動系，表 與此振動系的共振頻率frl相等之頻率的外力，作 振動中的情况，迅速將外力變爲零之後不久的振幅 變化例。 第4A圖係振動系之損失較少的情況。 第4B圖係振動系之損失稍大的情況。 動磁鐵 突到停 身的損 振動型 旋彈簧 旋彈簧 力在平 i子15 共振頻 失。但 摩擦阻 ，隨著 示施加 爲正常 之時間 -12- 200934065 如第4B圖所示，振動系的損失大的情況，迅速地將外 力變爲零時’振動急速地減少。即，如第4A圖所示，振動 系的損失盡量使之減少時’因爲可動磁鐵的振動時間會變 . 長，所以可長時間地獲得電壓。 . 第5A、5B圖係於第3圖所顯示之振動系施加周期性衝 擊力時表示墜子15的振幅。 脈動狀的衝擊力包含寬廣的頻率成分，也包含振動系 ^ 的共振頻率成分。因此’透過共振頻率成分的作用振動系 會被激勵。結果，墜子會如第5A、5B圖所示進行振動。 第5 A圖係振動系的損失較少的情況。 第5B圖係振動系的損失稍大的情況。 如第5A、5B圖所示’振動系的損失小時振動會長時間 繼續。另一方面，若損失大時，振動會迅速地減少。因此 . ，在損失小時振幅也會變大。 第6圖係將質量Μ的墜子15在垂直方向由2個螺旋彈 0 簧17、18懸吊所構成的振動系之示意圖。螺旋彈簧17、18 的彈簧常數分別爲kl、k2。在第6圖中向下設爲重力的方 向，因爲施加墜子之重力，使上側的螺旋彈簧17被拉長之 墜子15的位置成爲靜止點零。墜子15的振動係以靜止點 零爲中心而進行。在如此振動系之共振頻率fr2’可以次式 (2)表示。 【第2式】 fr2= 1 /2 π Vki + k2/M ..........(2) 由第（2)式可知共振頻率fr 2係由於螺旋彈簧Π的彈簧 -13- 200934065 常數kl，與螺旋彈簧18的彈簧常數k2之和而變高。因此 ，若在墜子15施加振動時，於既定的時間內墜子15的振 動次數會變多。 . 根據以上所說明之有關第1實施形態之振動型電磁發 電機1，可動磁鐵3超越既定的振幅而振動時，可動磁鐵3 的振動會透過第1停止器6a與第2停止器6b而受到限制 。因此，彈性體不會加上多餘的應力，而可防止彈性體的 0 破損。結果，對於振動型電磁發電機1，可抑制零件修理 等維修頻率，而且振動型電磁發電機1，具有可經過長期 發電之效果。 又，振動型電磁發電機1，可建構由於可勤磁鐵3的 質量，第1螺旋彈簧5a及第2螺旋彈簧5b的彈簧常數所 決定之共振系統。而且，選擇管2的材質，透過使與可動 . 磁鐵之間的摩擦係數變小，不會使可動磁鐵3之振動長時 間地減振。如此，則具有可提高振動型電磁發電機1之發 Q 電效率的效果。又，如第1圖所示之形態例，從可動磁鐵 3的兩端到管2的兩端，即將第1及第2螺旋彈簧5a、5b 配置直到第1及第2的端構件7a、7b。藉由如此配置，可 使振動型電磁發電機1朝任何方向均可獲得效率良好的發 電效果。 又，對預先量測之可動磁鐵3的質量’藉由選擇第l· 螺旋彈簧5a及第2螺旋彈簧5b之彈簧常數’可任意的調 整共振頻率。因此，可獲得適合用途之發電效率高的振動 型電磁發電機1之效果。 • 14- 200934065 又，若使用振動型電磁發電機1時，可使微弱的振動 能有效率地轉換成可動磁鐵3的直線往復運動。因此，即 使振動型電磁發電機1對於重力方向爲平行的狀態，而且 . 振動型電磁發電機1之設置方向爲一定的情况，例如，爲 了海上船舶的安全航行透過波浪的上下運動而發電發光之 發光浮標等之作爲發電機可說適當。又，附帶由於具有停 止器，即使發生強烈的振動，振動型電磁發電機損傷之憂 u 慮少，亦可採用於腳踏車的貨架或座椅，及汽車的懸吊裝 置等。 又，於振動型電磁發電機1施加脈動狀的衝擊力時， 藉由含在其衝擊力之中的自身兵振頻率之成分可動磁鐵3 會被激勵。因此，也具有外力的頻率未必然要與振動型電 磁發電機1之共振頻率附合即可的效果。 . 又，可解決以往振動型電磁發電機成爲問題之藉由使 用彈回用的磁鐵而造成成本提高與共振系的不平衡，及在 Q 非磁性管的端面將彈回用彈簧以不接觸可動磁鐵的狀態配 置時所產生的噪音，與隨著振動效率的劣化而使發電效率 降低之問題的效果。 其次，參照第7A、7B圖說明有關本發明之第2實施形 態之振動型電磁發電機30的構成例。此外，在第7A、7B 圖中，對應於第1圖及第2A、2B圖已經在第1實施形態說 明之部分賦予同一符號，而省略詳細說明。 第7A圖係顯示振動型電磁發電機30的截面圖。 第7B圖係顯示停止器的構成例。 -15- 200934065 如第7A圖所示，第1螺旋彈簧3 2a與第2螺旋彈簧 32b都是壓縮彈簧。第1螺旋彈簧32a與第2螺旋彈簧32b 透過與可動磁鐵3之兩端部的接觸，將可動磁鐵3可振動 地支撐在發電線圈9的捲軸方向。此種情況下，因爲第1 及第2螺旋彈簧3 2a、3 2b相互壓縮可動磁鐵3而支撐，所 以不需要使用在第1實施形態中的磁鐵端構件8a、8b，而 可使構成簡略化。 又，在位於管2之兩端附近的位置之內壁，形成4個 突起部。該等突起部分別作爲第1停止器31a與第2停止 器31b。第1停止器31a及第2停止器31b與可動磁鐵3接 觸的位置，若以’管2的端部7a、7b爲起點時，係在較第1 螺旋彈簧32a與第2螺旋彈簧32b收縮最大時之長度更長 的位置。而且，較垂直於發電線圈9之捲軸方向之方向的 可動磁鐵3的截面徑，使第1停止器6a或第2停止器6b 接觸於可動磁鐵3之部位的寬度小。因此，超過既定的振 幅振動之可動磁鐵3，在第1停止器6a或第2停止器6b 與可動磁鐵3接觸的位置振動即受到限制。 此外，管2與停止器一體形成的情況，使管2成型筒 狀時，由於突出之停止器使可動磁鐵不可能封入。因此， 將與管2的長度方向平行分開成型之管構件的嵌合之構成 ，及在管2的中央部與長度方向垂直分爲2，而在其接縫 部分設置有螺紋/螺溝之管構件，使其螺合結合之構成亦可 〇 在此，著眼於第1停止器31a說明其機能與效果。構 -16- 200934065 成第1停止器31a之4個突起部頂點的寬度，係較第1螺 旋彈簧3 2a的捲繞半徑更廣，即，螺旋彈簧伸縮運動時， 使成爲停止器不會干涉的尺寸條件，而被固定在管2的內 . 壁。因此，第1螺旋彈簧32a的伸縮，不會受到第1停止 器31a的限制。但，4個突起部之頂點的寬度，因爲被設定 比可動磁鐵3的截面直徑狹窄，所以4個突起部之頂點形 成可確實地與可動磁鐵3接觸。因此，第1螺旋彈簧32a φ 在收縮最大時之前階段，可動磁鐵3於4個突起部之頂點 附近接觸，而限制可動磁鐵3的振動。結果，可獲得回避 收縮最大時之狀態的第1螺旋彈簧3 2a施加過剩的應力， 巢1螺旋彈簧3 2a及可動磁鐵3破損之危險性的效果。又 ，關於第2停止器31b亦可獲得同樣的效果。 而且，振動型電磁發電機30,係僅將第1螺旋彈簧32a -

OBJECTS OF THE INVENTION: TECHNICAL FIELD The present invention relates to a vibration type electromagnetic generator, for example, in a power generating coil composed of a plurality of electromagnetic coils, at least one magnet is magnetized by a length direction. The vibration generates electricity. [Prior Art] In recent years, the popularity of portable electronic devices such as mobile phones and amusement machines has increased, and the amount of secondary batteries incorporated therein has gradually increased. Moreover, with the development of wireless technology, the application of RFID (Radio Frequency IDentification) by small power transmission signals has become widespread. In particular, active RFID with power supply can also communicate hundreds of meters. Therefore, the application of the health management of cattle and horses in the pastures, and the safety management of school children when they go to school are highly expected. On the other hand, in order to improve the maintenance of the global environment, batteries with as little environmental burden as possible are actively being developed. Among them, the power that is usually unintentionally and wastefully converted into electric energy, charged, and reused as a power source for carrying a machine is widely considered. Patent Document 1 discloses a vibration type electromagnetic power generator that generates electric power by vibration from the outside. Here, a configuration example of the vibration type electromagnetic power generator 100 will be described with reference to Fig. 11 . The vibration type electromagnetic generator 100 includes a tube 102 formed of a non-magnetic material, and a rod-shaped movable magnet 101 that is accommodated in the tube 102 and magnetized in the longitudinal direction. At the central portion of the tube 102, a power generating coil 103 is formed. The magnets 104a and 104b are provided in a state in which both end portions of the tube 102 are opposed to each other with the same polarity as the polarity of the movable magnet 101. When the movable magnet 101 vibrates in 200934065, the movable magnet 101 is prevented from coming into contact with both end portions of the tube 102. Patent Document 2 discloses a hand cylinder equipped with a vibration type electromagnetic power generator that transmits light from the outside by vibrating from the outside. Here, a configuration example of the flashlight no will be described with reference to FIG. The flashlight 110 includes a tube 112 formed of a non-magnetic material, and a rod-shaped movable magnet 111 that is magnetized in the longitudinal direction of the tube 112. Compression springs 114a and 114b are provided at both end portions of Φ 112. By the action of the pressure springs 114a, 114b, the movable magnet 111 is prevented from coming into contact with the end of the tube 112. An electromagnetic coil 113 is formed at a central portion of the tube 112. The inside of the tube 1 is transmitted through the vibration of the movable magnet 111, and the electromagnetic coil 113 generates a pressure to cause the LED 115 to emit light. Through this illuminating light, the light emitted by the LED 115 is diffused by the lens 116 and irradiated to the object. [Patent Document 1] Japanese Patent Laid-Open Publication No. 2002-28 No. 727 Patent Document 2: U.S. Patent No. 5,975,714, the disclosure of which is incorporated herein by reference. The outer casing needs to be equipped with two magnets at both ends of the tube. This electromagnetic generator is generally required to generate electricity as much as possible in a small size state. Therefore, there is a need for a high magnetic flux density. Thus, the ratio of the cost of magnetism to the overall cost is higher. Therefore, the conventional vibration type motor generator 100 is disadvantageous in terms of cost. Further, the weight of the vibration type electromagnetic power generator is increased by the use of magnetic power. For example, there is a problem that fatigue is increased when power generation is performed by hand operation. The electrician's hand is closed by two 12 electric straight type large iron magnets. 200934065 Also, since the rebound force of the magnet is different from the spring return force by the spring, the rebound force is not proportional to the moving distance of the movable magnet. Therefore, it is revealed that the vibration of the common vibration determined by the mass of the movable magnet and the spring constant of the coil spring may cause a different behavior, and the vibration of the movable magnet may not last for a long time. As a result, the repulsive force of the magnet cannot be effectively converted into a vibrating motion, and does not have an effect of improving the power generation. Further, in the technique disclosed in Patent Document 2, when the flashlight is applied to the flashlight 110, the movable magnet 111 temporarily leaves or collides from the coil spring. Therefore, the movable magnet and the coil spring cannot be constructed to constitute a stable resonance system, and power generation efficiency cannot be improved. Further, since the movable magnet and the coil spring collide with each other, a collision sound occurs, so that the user is pierced. Furthermore, the speed of the generator, when the movable magnet passes through the power generating coil, contributes to the power generation (output voltage). Therefore, in order to obtain more power generation, it is necessary to give more intense vibration, so that the coil spring is easily broken by the intense collision between the movable magnet and the coil spring. The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a vibration type electromagnetic power generator that constructs a stable resonance system while making the coil spring less susceptible to breakage. A vibrating electromagnetic generator according to the present invention includes: a hollow tube formed of a non-magnetic material; at least one power generating coil wound around the tube; and at least one magnet is disposed in the tube a movable magnet; an elastic body fixed to at least one end of the tube and rotatably supporting the movable magnet in a reel direction of the power generating coil; and a stopper for restricting vibration of the movable magnet. The stopper is formed at at least one end of the tube, and the position at which the stopper is in contact with the movable magnet of the 200934065 is located at a position longer than the length at which the elastic body contracts the most when the end portion of the tube is used as a starting point. In such a configuration, in the state in which the elastic body is used to form a stable resonance system, unnecessary stress is not added to the elastic body having the largest shrinkage. Therefore, it is possible to obtain a vibration type electromagnetic generator which does not break even when the elastomer is used for a long period of time and which can generate stable resonance vibration. According to the present invention, by supporting the movable magnet with the elastic body, it is possible to obtain a vibration type electromagnetic power generator which constitutes a stable resonance system. Further, when the movable magnet vibrates beyond a predetermined amplitude, the vibration of the movable magnet is restricted by the stopper, and the elastic body does not apply excessive stress, and the elastic body can be prevented from being damaged. Therefore, with the vibration type electromagnetic generator', the frequency of maintenance can be suppressed, and the vibration type electromagnetic generator can have the effect of generating electricity over a long period of time. Further, since the coil spring can be used as the elastic body, the component cost can be reduced, and the weight of the vibration type electromagnetic generator can be reduced. [Embodiment] BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a first embodiment of the present invention will be described with reference to Figs. 1 to 6 . In the embodiment of the present embodiment, a plurality of cylindrical magnets magnetized in the longitudinal direction are applied, and the vibration type electromagnetic generator 1 that generates vibration by vibration or movement in a plurality of electromagnetic coils is applied as an example. First, a configuration example of the vibration type electromagnetic generator 1 according to the present embodiment will be described with reference to a cross-sectional view of Fig. 1. The vibration type electromagnetic generator 1 is composed of a movable magnet 3 and three electromagnetic coils (first electromagnetic coil 4 & ~ third electromagnetic coil 4c). Three electromagnetic coils, which are attached to the outer circumference of the hollow tube 2, 200934065, Yu Cheng. The magnet wire and the counter coil are arranged to form iron. (The magnetic tension of the magnetic reversal 10 is composed of a magnet spring 5b. The magnet 3 is reciprocated linearly inside the tube 2 through the movable magnet 3, and three electromagnetic coils vibrate to generate a voltage. The tube 2 is made of a non-magnetic material, and the material of the tube 2 may be a non-magnetic material such as metal. However, it is preferably made of a synthetic resin such as plastic if the workability is the same. And a plurality of electromagnetic coils having opposite polarities are connected in series by a predetermined interval state. The winding direction of the electric coil is a positive and positive direction in which the adjacent electromagnetic coils are opposite to each other. In the above description, the first electromagnetic 4&~ third electromagnetic coil 4c connected in series is referred to as a power generating coil 9. At least one power generating coil 9 is built in the tube 2. The movable magnet 3 is opposed to the same pole. A plurality of magnetic bodies joined, for example, neodymium magnets. In the movable magnet 3 of the present embodiment, the two magnets 3a and 3b of the same length which are magnetized in the longitudinal direction are joined to each other with the same polarity interposed therebetween by sandwiching the predetermined thickness of the iron separator 10. The material of the magnet spacer 1 can be either a magnetic body or a non-magnetic material. Further, at least one magnet of the movable magnet 3 may be formed. At one end of the movable magnet 3, the protective magnet 3a is formed with the iron end member 8a. Similarly, the magnet end member 8b is formed with a magnet end member 8b for protecting the magnet 3b at the other end portion of the movable magnet 3, in which the magnet end member 8a is drilled with a fine hole for attaching the spring. A second hole is drilled in the end member 8b to mount a tension spring. However, the magnet end members 8a and 8b may be formed in the shape of a hook or the like, and the first coil spring 5a and the second coil spring 5b may be attached. In the vibration type electromagnetic generator 1, the movable magnet 3 is vibrated in the direction of the reel of the power generating coil 9 through the first coil springs 5a to 200934065 and the second coil springs 5b. The first end member 7a and the second end member 7b made of resin or the like are fitted to both ends of the tube 2 to prevent the movable magnet 3 from flying out. The first end member 7a has the same shape as the second end member 7b, and each has a fixing portion for fixing the end portions of the first coil spring 5a and the second coil spring 5b. However, a hole or a hook or the like may be formed in the first end member 7a and the second end member 7b, and the end portions of the first coil spring 5a and the second coil spring 5b may be fixed. According to the vibration type electromagnetic generator 1 of the present invention, as described above, the adjacent three electromagnetic coils are connected in series in a state of being separated by a predetermined interval, and the winding direction thereof is reversed by the electromagnetic coils adjacent to each other. It is composed of positive, negative and positive directions. Therefore, the voltage generated by each electromagnetic coil becomes a state of phase synthesis, and the output voltage can be increased by synthesis. For this reason, it is necessary to make the length of the magnet plus the magnet spacer of the thickness of the magnet spacer substantially equal to the coil pitch of the coil length plus the coil spacing. Further, it is preferable to make the coil length of the electromagnetic coil shorter than the length of the magnet. The first coil spring 5a and the second coil spring 5b are coil springs having the same spring constant and the same natural length. However, the spring constant and natural length of each helical spring can also be changed depending on the specifications. In the vibration type electromagnetic generator 1 of the present embodiment, each of the first coil spring 5a and the second coil spring 5b is configured to be in a state in which the movable magnet 3 is pulled. At this time, when an external force is applied to the vibration type electromagnetic generator 1, the movable magnet 3 is a resonance frequency determined by the mass of the movable magnet 3 and the spring constant of the first coil spring 5a and the second coil spring 5b - 10 - 200934065 Fr to vibrate. As a result, the vibration time of the movable magnet 3 becomes long, and a long-time voltage can be obtained. Next, a configuration example of a stopper for mitigating the impact of the movable magnet on the end portion of the tube 2 will be described with reference to FIGS. 2A and 2B. In the second and second embodiments, the first stopper 6a will be described. However, the second stopper 6b has the same configuration. Fig. 2A is an extended state view of the first coil spring 5a. Fig. 2B is a state diagram in which the first coil spring 5a is shortened to the shortest. Further, the width 11 of the portion where the first stopper 6a is in contact with the movable magnet 3 is smaller than the sectional diameter 12 of the movable magnet 3 perpendicular to the direction of the reel of the power generating coil 9. In other words, the coil spring does not interfere with the stopper during the telescopic movement, and since the stopper forms a positive contact with the movable magnet 3, the movable magnet 3 that vibrates beyond the predetermined amplitude is attached to the first stopper 6a and When the position where the movable magnet 3 contacts, the vibration is restricted. As shown in Figs. 2A and 2B, the height l〇a of the first stopper 6a starting from the first end member 7a sets the height l〇b of the first φ coil spring 5a in a state where the contraction is maximum. higher. Further, when the movable magnet has a state vibration that exceeds the kinetic energy of a predetermined amplitude, the upper end of the first stopper 6a becomes a contact/collision. Therefore, the amplitude of the first stopper 6a is limited. Further, since the first stopper 6a is formed of a resin such as elastic rubber, the impact of the movable magnet 3 may be alleviated. Therefore, although the first coil spring 5a is in the state of maximum contraction, it is possible to effectively suppress the breakage of the coil spring which occurs when the movable magnet 3 collides and excessive stress is applied. Here, when the first and/or second end members 7a and 7b and the stopper 6a are integrally formed, it is desirable to select a hard and elastic -11-200934065 rubber and resin. The material is selected in order to reliably seal the vibration of the tube 2 inside the tube 2. Further, since the movable magnet 3 is stopped by the stopper 6a, the coil spring is not damaged, and the stopper can be prevented from being injured. Here, the vibration characteristics of the electromagnetic generator 1 according to the present invention will be described with reference to Figs. 3 to 6 . Fig. 3 is a schematic view showing a vibration system in which a weight 15 and a screw 16 of a spring constant k are combined. When the sinker 15 is suspended from the snail 16, the restoring force of the coil spring 16 and the balance of the weight of the sinker 15 will be static. This position is set to zero displacement. E If the external force is applied, the sinker 15 starts to vibrate. The rate of this vibration system can be expressed by the following formula (1). [Formula 1] fn = (l/2 π )(k/M).... (1) However, in Fig. 3, the vibration loss due to friction or the like is not shown in reality. The vibration system has various forces including the force of the viscous resistance of the air and the internal friction of the vibrating body itself. Therefore, the amplitude of the passage of time will be reduced and the resonance frequency will be slightly reduced. 4A and 4B are examples of the amplitude change of the vibration system shown in Fig. 3, the external force of the frequency equal to the resonance frequency frl of the vibration system, and the case where the vibration is rapidly changed to zero after the external force is zero. . Fig. 4A shows a case where the loss of the vibration system is small. Fig. 4B shows a case where the loss of the vibration system is slightly large. The moving magnet protrudes to the stop. Vibration type Rotating spring The spring force is lost in the resonance of the flat. However, the frictional resistance is applied as normal time -12-200934065 As shown in Fig. 4B, when the vibration system has a large loss, the external force is rapidly changed to zero, and the vibration is rapidly reduced. In other words, as shown in Fig. 4A, when the loss of the vibration system is reduced as much as possible, the vibration time of the movable magnet is long, so that the voltage can be obtained for a long time. 5A and 5B show the amplitude of the sinker 15 when the vibration system shown in Fig. 3 applies a periodic impact force. The pulsating impact force includes a wide frequency component and also includes the resonance frequency component of the vibration system ^. Therefore, the vibration system that is transmitted through the resonance frequency component is excited. As a result, the sinker vibrates as shown in Figs. 5A and 5B. Fig. 5A shows a case where the loss of the vibration system is small. Fig. 5B shows a case where the loss of the vibration system is slightly large. As shown in Figures 5A and 5B, the vibration of the vibration system will continue to vibrate for a long time. On the other hand, if the loss is large, the vibration will rapidly decrease. Therefore, the amplitude will also increase in the hour of loss. Fig. 6 is a schematic view showing a vibration system in which a weighted pendant 15 is suspended by two spiral springs 09 and 18 in the vertical direction. The spring constants of the coil springs 17, 18 are kl and k2, respectively. In Fig. 6, the downward direction is set to the direction of gravity, and the position of the sinker 15 in which the upper coil spring 17 is elongated becomes the stationary point zero because of the gravity of the sinker. The vibration of the sinker 15 is centered on the stationary point zero. The resonance frequency fr2' of such a vibration system can be expressed by the following equation (2). [Formula 2] fr2= 1 /2 π Vki + k2/M (2) From the equation (2), the resonance frequency fr 2 is due to the spring of the coil spring -13-13- 200934065 The constant kl becomes higher than the sum of the spring constant k2 of the coil spring 18. Therefore, when vibration is applied to the sinker 15, the number of vibrations of the sinker 15 increases in a predetermined period of time. When the movable magnet 3 vibrates beyond a predetermined amplitude, the vibration of the movable magnet 3 is transmitted through the first stopper 6a and the second stopper 6b. limit. Therefore, the elastomer does not add excessive stress, and it can prevent the 0 of the elastomer from being damaged. As a result, the vibration type electromagnetic generator 1 can suppress the maintenance frequency such as repair of parts, and the vibration type electromagnetic generator 1 has an effect of generating power over a long period of time. Further, the vibration type electromagnetic power generator 1 can construct a resonance system whose spring constant is determined by the spring constant of the first coil spring 5a and the second coil spring 5b due to the mass of the movable magnet 3. Further, the material of the tube 2 is selected so that the friction coefficient between the movable magnet and the movable magnet is reduced, and the vibration of the movable magnet 3 is not damped for a long period of time. Thus, the effect of improving the power efficiency of the vibration of the vibration type electromagnetic power generator 1 is obtained. Further, as shown in the first embodiment, the first and second coil springs 5a and 5b are disposed from the both ends of the movable magnet 3 to both ends of the tube 2 to the first and second end members 7a and 7b. . With this configuration, the vibrating electromagnetic generator 1 can obtain an efficient power generation effect in any direction. Further, the resonance frequency can be arbitrarily adjusted by selecting the spring constant ' of the first coil spring 5a and the second coil spring 5' for the mass of the movable magnet 3 measured in advance. Therefore, the effect of the vibration type electromagnetic generator 1 having high power generation efficiency suitable for the application can be obtained. • 14- 200934065 When the vibration type electromagnetic generator 1 is used, the weak vibration energy can be efficiently converted into the linear reciprocating motion of the movable magnet 3. Therefore, even if the vibration type electromagnetic generator 1 is in a state in which the direction of gravity is parallel, and the direction in which the vibration type electromagnetic generator 1 is set is constant, for example, for the safe navigation of a marine vessel, power is generated by the up and down movement of the waves. A light-emitting buoy or the like can be said to be suitable as a generator. Further, with the use of a stopper, even if a strong vibration occurs, the vibration type electromagnetic generator is less likely to be damaged, and it can be used in a bicycle shelf or a seat, and a suspension device for a car. Further, when the pulsating impact force is applied to the vibration type electromagnetic generator 1, the movable magnet 3 is excited by the component of the own munition frequency included in the impact force. Therefore, the frequency of the external force is not necessarily the effect of being attached to the resonance frequency of the vibration type electromagnetic generator 1. Further, it is possible to solve the problem that the conventional vibration type electromagnetic generator has a cost increase and a resonance system imbalance by using a magnet for bounce, and the spring is not contacted at the end face of the Q non-magnetic tube. The noise generated during the state of the magnet arrangement and the effect of lowering the power generation efficiency as the vibration efficiency deteriorates. Next, a configuration example of the vibration type electromagnetic power generator 30 according to the second embodiment of the present invention will be described with reference to Figs. 7A and 7B. In the first and second embodiments, the same reference numerals are given to the first embodiment and the second and second embodiments, and the detailed description is omitted. Fig. 7A is a cross-sectional view showing the vibration type electromagnetic generator 30. Fig. 7B shows an example of the configuration of the stopper. -15- 200934065 As shown in Fig. 7A, the first coil spring 32a and the second coil spring 32b are both compression springs. The first coil spring 32a and the second coil spring 32b are in contact with both end portions of the movable magnet 3, and the movable magnet 3 is vibratedly supported in the spool direction of the power generating coil 9. In this case, since the first and second coil springs 3 2a and 3 2b are supported by compressing the movable magnet 3, it is not necessary to use the magnet end members 8a and 8b in the first embodiment, and the configuration can be simplified. . Further, four projections are formed on the inner wall of the position near the both ends of the tube 2. These projections serve as a first stopper 31a and a second stopper 31b, respectively. When the first stopper 31a and the second stopper 31b are in contact with the movable magnet 3, when the end portions 7a and 7b of the tube 2 are used as the starting point, the first coil spring 32a and the second coil spring 32b are contracted the most. The longer the length of the position. Further, the cross-sectional diameter of the movable magnet 3 in the direction perpendicular to the winding direction of the power generating coil 9 is such that the width of the portion where the first stopper 6a or the second stopper 6b contacts the movable magnet 3 is small. Therefore, the movable magnet 3 that exceeds the predetermined amplitude vibration is limited in vibration at the position where the first stopper 6a or the second stopper 6b is in contact with the movable magnet 3. Further, in the case where the tube 2 is integrally formed with the stopper, when the tube 2 is formed into a cylindrical shape, the movable magnet cannot be sealed due to the protruding stopper. Therefore, the fitting of the tubular member which is formed separately from the longitudinal direction of the tube 2 is divided into two, and the tube is provided with a thread/coiled tube at the joint portion thereof in the center portion of the tube 2 and perpendicularly to the longitudinal direction. The structure in which the members are screwed together may be described here, and the function and effect of the first stopper 31a will be described. 6-1 - 200934065 The width of the apex of the four projections of the first stopper 31a is wider than the winding radius of the first coil spring 32a, that is, when the coil spring is telescopically moved, the stopper does not interfere. The dimensions of the condition are fixed inside the tube 2. The wall. Therefore, the expansion and contraction of the first coil spring 32a is not restricted by the first stopper 31a. However, since the width of the apex of the four projections is set to be smaller than the cross-sectional diameter of the movable magnet 3, the apex of the four projections can surely come into contact with the movable magnet 3. Therefore, the first coil spring 32a φ is in contact with the vicinity of the apex of the four projections before the maximum contraction, and the vibration of the movable magnet 3 is restricted. As a result, it is possible to obtain an effect of applying excessive stress to the first coil springs 3 2a in the state in which the contraction is maximum, and the risk of damage of the nest 1 coil springs 3 2a and the movable magnets 3. Further, the same effect can be obtained with respect to the second stopper 31b. Further, in the vibrating electromagnetic generator 30, only the first coil spring 32a- and the second coil spring 32b are enclosed in the tube 2 to constitute a vibration system. Therefore, on the one hand, it is easy to pass through the coil spring for a long time, and the efficiency is good and the power generation is good. Further, in the vibrating electromagnetic generator 30 according to the second embodiment, four projections are formed as the stoppers, but the number of the projections may be less than four or more than four. Further, the protruding portion is not limited to the shape shown in Fig. 7B. Any shape can be restricted as long as it can restrict the vibration of the movable magnet 3 beyond an appropriate amplitude or suppress the impact toward the end portion and the unnecessary stress to the coil spring. Further, regarding the vibration type electromagnetic generator 30 of the second embodiment, two compression springs are used. However, it is also possible to use only one compression spring. In the case of the case, the compression spring is disposed in the gravity direction (lower side) of the movable magnet 3, and the magnet end member 8a is fixed to the first end member 7a. Even with this configuration, appropriate power generation can be performed. Further, when a compression spring is used as the coil springs 32a and 32b, it is preferable that the stopper is provided on the inner diameter side of the coil spring. A configuration example of the vibration type electromagnetic power generator configured as above will be described with reference to Fig. 8. Further, in Fig. 8, the state 0 of the stopper 33 of the first coil spring 32a is shown, but the stopper 33 of the second coil spring 32b has the same configuration. The movable magnet 3 is sealed to the first end member 34 of the tube 2, and is cylindrical, and a stopper 33 having a tapered surface is formed at the tip end. Further, the first coil spring 32a is provided in the first end member 34. On the other hand, the first coil spring 32a is vibrated by the stopper 33 without causing a positional movement. The movable magnet 3 that vibrates beyond a predetermined amplitude is in contact with the top surface of the stopper 33, and the vibration is restricted. However, when the top end of the stopper 33 is in contact with the movable magnet 3, the first end member 34 is located at a position longer than the length at which the first coil spring 32a is maximally contracted. Therefore, the first helical springs 3 2a having the largest contraction do not apply excessive stress, and the effect of avoiding the breakage of the first coil springs 32a can be obtained. Further, since the stopper is formed into a tapered shape, the expansion and contraction movement of the coil spring can be performed without interference. Further, in the second embodiment described above, when the inner circumferential diameter of the tube 2 is compressed by a coil spring (compression spring) in a state where the spring diameter of the coil spring is small, the coil spring is compressed in a warped state. In this state, in the worst case, it is expected that the compression of the coil spring will be interfered by the -18-200934065 of the stopper. Therefore, as a more preferable example, it is preferable to make the spring diameter of the coil springs 32b slightly smaller than the inner circumference diameter of the tube 2. By configuring, since the compression spring is regularly compressed, the coil spring is not interfered by the stopper even when it is being retracted, and the function of the device can be sufficiently obtained. Next, a configuration example of the vibration type electromagnetic power generator 40 according to the third embodiment of the present invention will be described with reference to Figs. 9A and 9B. In the ninth embodiment, the same reference numerals are given to portions corresponding to those in the first embodiment and the second embodiment, and the detailed description is omitted. Fig. 9A is a cross-sectional view showing the vibration type electromagnetic generator 40. Fig. 9B shows a configuration example of a rod stopper. Holes are formed in the side surface of the tube 2 for inserting two rod-shaped stoppers. Two rod-shaped stoppers inserted into the holes are used as the first stopper and the second stopper 41b, respectively. The position where the first stopper 41a and the second stopper 41b are in contact with the movable magnet 3 is a position longer than the end of the tube 2 when the first coil spring 5a and the second coil spring 5b are contracted the most. Here, focusing on the first stopper 41a, two rod-shaped stoppers whose functions and effects are the first stoppers 41a are described, and are composed of non-magnetic or metal, and are smaller than the winding radius of the first coil spring 5a. Widely fixed to the inner wall of the tube 2. Therefore, the expansion and contraction of the first coil spring 5a is not limited by the stopper 41a. However, the width of the two rod-shaped stoppers is narrower than the diameter of the cross-section of the iron 3. Therefore, the first coil spring 5a contracts most, and the movable magnet 3 comes into contact with the two rod-shaped stoppers, and the movable magnetism = 32a is restricted to the above-described pressure stop and the shape is 9B 2A. When 4 1a is tied, the length. The width of the resin is affected by the vibration of the iron 3 -19- 200934065. As a result, it is possible to avoid the danger of the first coil spring 5a or the movable magnet 3 being damaged by the first coil spring 5a in a state where the contraction is maximized by the excessive stress. Further, the second stopper 41b can also be used. With the same configuration, the same effect can be obtained at the same time. Further, in the vibration type electromagnetic generator 40 of the third embodiment, two rod-shaped stoppers are inserted as the stopper, but the number of the rod-shaped stoppers may be less than two or more than two. Further, the shape of the rod stopper is not limited to the shape of Q as shown in Fig. 9B. For example, the cross-sectional shape of the rod stopper may also be polygonal or elliptical. The shape of the rod stopper is as long as it can restrict the vibration of the movable magnet 3 from exceeding an appropriate amplitude, or suppress the collision with the end portion and the unnecessary stress in the shape of the coil spring, and any shape is severe. Next, a configuration example of the vibration type electromagnetic power generator 50 according to the fourth embodiment of the present invention will be described with reference to Fig. 10. In the first embodiment, the same reference numerals are given to the portions corresponding to the first and second embodiments, and the description of the first embodiment and the second and second embodiments are omitted. In the vibration type electromagnetic power generator according to the first to third embodiments, the coil springs are disposed on both sides of the movable magnet 3. However, as in the present embodiment, a vibration system may be formed by the one coil spring and the movable magnet 3. In the second end member 51 of the tube 2, projections, hooks, pores, and the like for fixing the coil spring are not formed. Therefore, the second end member 51 has only the function of sealing the movable magnet 3 to the tube 2. The vibrating electromagnetic generator 50' passes through the first coil spring 5a, and the movable magnet 3 is oscillatably supported in the reel direction of the power generating coil 9. -20- 200934065 When an external force is applied to the vibration type electromagnetic generator 50, it will vibrate. This vibration is based on the mass of the movable magnet 3 and the spring constant of the fifth, and the vibration-type electromagnetic generator 50 shown in the above-described equation (1) is the vibration-type electromagnetic generator 50 shown in Fig. 10, and only the spring is used. . Therefore, there is an effect that the assembly of each member is easy. The installation location of the electromagnetic generator 50 is suitable for the installation of the generator φ. In other words, when a tension spring is used as the coil spring, the screw magnet is placed on the upper side in the gravity direction, and the movable magnet can be suspended. On the other hand, when the coil spring is a compressed bomb, the movable spring is disposed on the lower side in the direction of gravity, and the movable magnet is constituted. Thus, the most appropriate method can be selected by the form of the vibration type electromagnetic generator 50. Further, in any of the above configurations, the movable magnet and the end structure φ spring are preferably fixed by hooks or the like, and the screw system can be fully utilized. Further, it is possible to obtain the effect of using two coil springs: the same power generation characteristics of the vibration type electromagnetic generator of the embodiment: In addition, in the first to fourth embodiments described above, the gap may be adjacent to each other, but may be In the first to fourth embodiments, the shape of the tube is formed into a cylindrical shape, but the cross-sectional shape may be multi-angled. , or the combination of a curve and a line. In this case, the electromagnetic movable magnet 3 1 has a spiral spring frequency frl, and the vibration type direction is applied to the gravity coil spring to the iron, that is, the magnet is used to lift the screw downward, and the setting member and the spiral spring are spring. The vibration of the first to the third fruit. Electromagnetic coils. Also, the magnet can be moved. And movable magnet shape, elliptical wire 圏 and magnet -21- 200934065 The cross-sectional shape of the spacer can be matched with the cross-sectional shape of the movable magnet. In the above-described first to fourth embodiments, the first to the second end members are attached to the both ends of the tube 2 in order to seal the movable magnet 3, but heat treatment or the like is applied thereto. The end portion of the tube 2 may be deformed to seal the movable magnet 3. Further, each of the stopper groups shown in the first to fourth embodiments described above may be combined. ◎ Further, the stopper may be formed at least at one end of the tube 2 in accordance with the number of the coil springs. Therefore, in the case of using one coil spring, one stopper is sufficient, and the formation of the member becomes easy. Further, the magnet end member may be provided at the end of the movable magnet 3 to which the coil spring is disposed. At the end of the movable magnet 3, since the end portions of the coil spring are in contact with each other, the magnet end member can be prevented from being damaged by the magnet end member. Further, the end portions of the magnet end member and the tube 2 may be joined by a coil spring. Further, a stopper is formed at both ends of the tube 2, and a coil spring ’ is disposed from both ends of the movable magnet from both ends of the movable magnet 3 of the tube 2 to both ends of the tube 2. By doing so, the movable magnet 3 can be reliably supported, and there is no loss of vibration energy, and the vibration can be continued for a long time.
