| dc.description.abstract | 本文探討以類鑽膜（Diamond-Like Carbon , DLC）鍍膜改善耳機振膜之響應。希望經由鍍上類鑽膜改變耳機振膜的振動響應，進而藉由不同的鍍膜形式改良耳機的性能。因為系統不存在解析解，本文利用有限元素法進行分析。首先建立耳機和標準電子耳的有限元素模型，以適當的範例驗證有限元素模型的正確性。依據振膜的幾何特徵，將振膜分為數個區域。在各個區域鍍上適當厚度的類鑽膜後計算振膜的頻率響應，由此了解類鑽膜的位置和厚度對振膜效能的影響。最後利用響應曲面法求得最好的鍍膜部位和厚度。 | zh_TW |
| dc.description.abstract | This paper aims to enhance the performance of the diaphragm of earphones by diamond-like carbon (DLC) films. It is desired to change the mode shapes of the diaphragm by the deposition of DLC films and hence improve the response of the earphone. Since the earphone-ear system is too complex for an analytical study, the finite element method is used in turn. A finite element model for the earphone and standard electronic ear is constructed first. Proper examples are used to verify the finite element model. Then the diaphragm is divided into several areas according to the geometric characteristics. The frequency response of the diaphragm is determined when DLC film of proper thickness is deposited on each area. The effects of the deposition position and thickness of the DLC film on the acoustical performance of the diaphragm are investigated in detail. Finally, the response surface method is used to determine the optimal location and film thickness of the DLC film. | en |
