It is fascinating to realize that early gramophones-composed of turntable, needle, resonator, and speaker-were like handicraft items. They needed no electricity, but instead were hand cranked, producing sound by the vibration of the needle as it passed along the grooves of the record.
奇妙的是，早期的留聲機就像工藝品，由轉盤、唱針、共鳴箱和喇叭構成，播放時不需要插電，而是用手搖旋緊齒輪發條，藉由指針滑過唱盤紋路時的共振原理重現聲音。
