請教電子名詞
各位ching知否overdamp及rolloff在喇叭來說是什麽意思? overdamp is...The power amp has too much control for the speaker and make the sound too tight. Directly in proportion to the damping factor of the amp.rolloff is frequencies cut of in a gradation order... 回復 2# xover
其實都係好明{:1_342:} ,但係都多謝{:1_347:} 回復 3# DBBoy
其實都5係好明 ,但係都多謝 唔洗客氣..{:1_253:}
有D專用詞唔係咁易明....有時間可留意人地講既時候係用响咩地方....你就可以有個大約概念... 圖中係一個seas喇叭單元既Frequencies response...高音段向下滑果一段就叫High frequency roll-off 而要明白over-damp,先要知道咩係Amp 嘅 Damping Factor...
Damping Factor係所有amp嘅阻尼系數...即係代表咗amp對喇叭既控制能力...(一般對低音而言)...
Damping factor越低...低音缐條越唔清...肥...矇...慢...
反之...越高則越清...收得緊...快....
例如Dyna及B&W...就要大一D damping factor既amp去推...否則變成肥婆坐塔...
至於點計算damping factor......要寫成本電話薄咁厚{:1_260:} {:1_336:}嗶,高深,但開始有點理解了。
多謝ching花時間解答{:1_326:}
