大家好...

我現在有一個計劃...

計劃主角是

1. 隨身訊源: 可以放MP3或APE的隨身聽

2. 功率夠大的耳機擴大器: 這個目前不知道要用什麼.. 但是希望是電池供電的..

3. 兩顆FOSTEX FE87E單體: 八歐母阻抗, 單體上面有標MUS 10W, NOM 5W, 這是什麼意思? 意思是放音樂可以承受十瓦的功率嗎??

所以訊源當然由隨身聽擔任, 經由一個耳擴去推動FOSTEX的兩個單體,

大家有沒有可以建議的擴大器?? 我自己看了看, 想用LC-KING的10 W版, 可是LC-KING有辦法改成用電池供電嗎??
又, 以10W推力的LC-KING推兩顆三吋全音域單體, 力道會夠嗎??

還是我這個問題應該到山寨去問??

要能夠推喇叭耳機,又要能夠趴趴走....好像有點難...

如果建議裝個 LM386 不知會不會給 K .....

就算要用電池也是至少車用的那種, 充電的問題也要考慮.
另外建議使用 FE127E, 比 87 大一點, 但是低頻多很多, 耐聽的多.

可能性太低...
要能推喇叭...
電池勢必不小
那光電池就多重了...
要帶著走...

知道問題會出在哪裡了..

謝謝大家的回應...

如果真的一定要電池供電, 可以考慮這個.
Class D 才夠有效率, 夠省電來使用電池.

這玩意是class T, based on Tripath chip.
class T 我想是 Tripath 的 marketing 名詞.
雖然文宣很普通, 但是聲音不錯, 有 SET 管機的味道.
