嗶聲；光點
核心畫面
You can think of blip as one tiny pulse from a machine: a dot that flashes once on a screen, with a short high beep at the same moment, and then nothing.

blip 可以想成機器吐出來的「一小下」：螢幕上閃一次的小亮點，配上一聲短短的高音，然後就沒了。它的重點不在內容，而在「小」跟「快」——你還沒轉頭，它就結束了。這個字後來長出的每個意思，都還帶著那一閃：機器發出那一聲、燈亮一下又滅、日子裡一下下就過去的小起伏。From the word’s history
Wiktionary records blip as onomatopoeic: the word was made to imitate the noise itself. That is why the machine's short note sits at the centre of the word.
Wiktionary 標示 blip 是狀聲字，也就是照著聲音造出來的。唸 blip 的時候，嘴巴幾乎就在模仿機器的那一聲。所以這個字的中心一直是那一聲，其他用法都從那一聲延伸出去。
