The sound a fidget makes, from crisp clicks to deep clacks and ringing pings.
What it is
Acoustics covers the character of the sound: click is short and sharp, clack is fuller and lower, ping is a ringing tone that lingers. Material, wall thickness and how parts meet all shape it.
Why it matters
Sound is half the experience for many players and a deciding factor in where you can use a fidget. Listings that describe sound honestly save a lot of returns.

是什么
声学指声音的特征：click 短而尖，clack 更饱满、更低沉，ping 是带余音的响声。材质、壁厚和零件的碰撞方式都会影响它。
为什么重要
对很多玩家来说，声音占了一半体验，也决定玩具能在哪些场合用。如实描述声音，能减少很多退货。
