專利原型
1. 本發明原型其關鍵功能為「可調後弦長機構」。 此一創新增強對具有琴橋系統之絃樂器家族帶來了新的開端。特意之調整能比以往更輕易得到準確後弦長，以達到其共鳴諧振效果。本關鍵機構基本解決百年來弦樂器之狼音(wolf tone)現象，不存在以外加質量兼有抑制聲音質量副作用問題。
2. 外觀上A.A.T.B相較於一般拉弦板而言其特具有可調區，並覆蓋皮革。可調後弦珠串於弦上，其弦珠位置決定後弦長撥弦音高。
3. 弦珠(調音珠)以弦張合力壓住皮革面，摩擦力使其產生自然穩定狀態。配合適當的尾繩長度(tailgut length)及個別弦珠設定後弦長撥弦音，運用技巧利用調音器、聽覺作適當設定，將帶來類似所謂”鈴聲”效果，並明顯感受弦音延續。
4. 組件可靠耐用，適合於具有拉弦板弦樂器，即使在小尺寸樂器如小提琴，或既有拉弦板改裝，均可享受後弦長調音帶來之大幅改變。
5. A.A.T.B 不可與無法調整後弦長之其他特殊產品混淆或相提並論，A.A.T.B為前所未有，真正實現具琴橋弦樂器全弦可調後弦長音之劃時代躍進。
1. This invention regards key function of adjustable after-length mechanism. This innovation brings new doors to enhance string instrument families especially with bridge systems. On purpose adjustment can easily find precisely after-length to match required dominated resonance than ever. This key function fundamentally solves “Wolf Tone phenomena “existed hundreds of string instruments without sound suppress side effects with usage of mass damper-based wolf-tone eliminators.
2. Appearance has an adjustable length zone with leather covering on top other than ordinary ones. The adjustable after-length beads led on strings are to determine after-string pluck pitch.
3. Friction is naturally stable from beads pressure activating with strings’ resultant forces. Appropriate skillful setting with tuner, hearing will bring “ringing “effect and perceiving prolonging sound. Tailgut length and individual string beads drive to define after-length by pluck string.
4. The assembly composition shows reliability and durability. It is suitable for string instrument families with bridge systems. It is for certain that people can enjoy huge change of varying afterstring length tuning even if they are small size instruments like violin with simple parts.
5. A.A.T.B can’t be compared with other products which are not able to define after-length individually on specified pitch nor to confused with. A.A.T.B is genuinely to fulfill all-string afterstring length pitch adjustment and bring Philharmonics to new harmonic era.
