具L型線圈特徵之音圈馬達手機相機模組設計
Design of VCM Actuator with the L-Shape Coil for Cellphone Camera Modules
摘要
近年來智慧型手機銷售量大增，因此吸引相當多的廠商投入此市場，激烈的市場競爭使得智慧型手機更快速的發展，在各方面的功能皆須不斷的進步，以利在這市場中不被淘汰，而手機相機模組正是受消費者注目的項目之一。在現今的智慧型手機中，具自動對焦之相機模組已相當普遍， 因此廠商將更高階之光學防手震功能導入手機相機模組中，使得智慧型手機之相機功能更加完整。 眾多的智慧型手機廠牌中，如：Apple, Samsung與HTC等，又以Apple所推出之智慧型手機最受關注，因此本論文將透過逆向工程研究搭在其智慧型手機上的相機模組，以利了解手機相機模組之特性與規格，並且搭配閱讀其他文獻與專利後，提出一款與各專利皆不同之磁路結構。而本論文之磁路結構利用線圈的可撓性，將線圈彎折成L型，使線圈搭配磁場方向產生所需之音圈力，並且其性能與尺寸方面皆優於比較對象。而在模擬與完整模組之設計後，本論文透過製作金屬雛形品進行實驗，以驗證具L型線圈特徵之音圈馬達手機相機模組的性能。亦將實驗結果與模擬進行比較，以證明具L型線圈特徵之音圈馬達手機相機模組設計能與模擬匹配，並且優於市售產品。

Recently, the sales of the smartphone grow intensely, thus more manufacturers go into operation. Competitive market makes the smartphone develop rapidly. Manufacturers have to progress in the functions of smartphone to avoid them being eliminated through competition. And to capture images using camera modules is one of the noticed function. These days, auto-focusing (AF) is the basic function on smartphones. And the optical image stabilizer (OIS) mechanism is designed in the high-end smartphones to enhance the function of the camera module. Among of the brands (for example: Apple, Samsung and HTC etc.), iPhone catches more consumers’ attention. Thus this thesis got more information and specification through the reverse engineering of the camera module on iPhone 6 Plus, and proposed a novel camera module in which the coils were folded into L-shape. After designing the complete module, this thesis evaluated its performance using a laboratory-built prototype. The simulation and experimental results showed that the proposed camera module is better than the camera module on iPhone 6 Plus.
