為什麼沒3.5耳機孔會有人反應這麼大 - iOS

先來說我是果粉
從ipod的年代就一直在使用蘋果產品
而蘋果在音樂播放器產品上課保持穩定的推力
跟在萬元價格就能有還不錯的頻率響應曲線
一直都是我沒有逃離蘋果的原因
iPhone 4 跟 iPod video更是物超所值
自從iPhone 7開始有取消耳機孔的傳聞
就一直很關注,直到板上討論越來越多
我才發現本版對於少了一個3.5mm耳機孔
影響了什麼事情不是很了解
給個簡單概念(非專業請見諒)
首先先從音樂怎麼來說起
人聲,樂器聲皆是一種能量
能量經由麥克風收音轉成電流
這時這些訊號是類比訊號
經過轉換而形成數位訊號儲存
而我們聽音樂時
數位訊號經由轉換再轉回類比訊號驅動音響
而3.5mm街頭就是一種類比輸出
而充電的lighting是數位輸出
這差異就非常大
我們稱數位轉類比轉換器為DAC
(Digital to Analog Converter)
當然DAC是在收聽音樂時很重要的部分之一
因為轉換過程中多少會有失真
如何能做到最小失真關鍵有一大部分在DAC
為什麼黑膠有他的價值就在於黑膠播放是不需轉換的,他本身就是類比訊號
而這次頻果取消耳機孔
很可能意味的是頻果以後只有數位輸出了
要是改個頭就能聽音樂
我想大家反應不會那麼大
而常有人提到的轉接器,他或許就是DAC
而DAC的價格,從幾百塊到5萬都有
這就是為啥有些人這麼緊張
可能要多花幾千元買個隨身DAC
再來就是常提到的藍芽耳機
基本上藍牙也是數位訊號
買個藍芽耳機等於買個DAC+耳機
這就是為啥同價位的藍芽耳機會比有線耳機差的原因
藍芽傳輸的瓶頸就先不提
以上是為什麼取消耳機孔會引起討論的原因
改了耳機孔可不是只有形狀改變
不是像萬用插座那樣線接對就好
這其中牽扯到了訊號轉換
當然也有可能還是有內建DAC然後lighting的幾個pin能使用類比訊號
只能等出來再觀望了
