摘要
鑒於MP3數位音樂播放隨身聽結合無線通訊的需求日殷,在本論文中,我們設計並改良一個具有藍芽無線耳機Hand-free/set功能的可攜式MP3數位音樂播放器系統。本系統包括MP3數位音樂播放器與耳機、麥克風和記憶卡、FM調頻廣播接收器與耳機,以及具有藍芽無線(Bluetooth Wireless)功能的行動電話和耳機之間都提供了無線傳輸功能。在我們的設計中是利用一組音源切換電路去提供相關音頻訊號所需經過的路徑。此外,為了滿足系統低消耗功率、減少重複充電次數和有效的延長使用時間的需求下,我們選用高整合度的晶片組來實現本系統的設計。我們也使用簡單的運算放大器,並利用其負回授設計出一組共模雜訊抑制電路,它能有效抑制介於音訊路徑上由高頻訊藕合產生的共模雜訊。整體來說,我們的原始設計已經可以展示具有藍芽無線耳機裝置的高品質MP3數位音樂播放器。
ABSTRACT
Considering the increasing demand for a wireless connection to a portable MP3 player, we propose the integration design of a MP3 Player with a Bluetooth hand-free/set. The Bluetooth module serves as the wireless channels between the MP3 player and wireless headphone, the wireless microphone and recording memory cards, the FM receiver, as well as the cellular phone. Audio switches in our design are used to facilitate the corresponding audio paths. We have chosen a highly integrated chip set to fulfill the required functions, resulting in less power consumption, and extension of the recharge cycle. In this integration design, we use a simple operational amplifier with a negative feedback circuit to suppress the common mode noise resulting from high frequency signal coupling between the audio paths. Overall, our prototype design has already demonstrated good sound quality for a wireless MP3 player.
