A tuning-fork structure produces a resonant tone and tactile vibration.
What it is
Tuning-Fork Resonance is feedback created by a tuning-fork-shaped part that vibrates when struck or released. Like a musical tuning fork, its shape, length and material set the pitch and how long the tone rings. In EDC, a built-in fork or tine can turn each movement into a clear, ringing note.
How it feels in your EDC
Instead of a dull click, you hear and feel a resonant tone that rings out and fades, often with a faint vibration in your fingers. Different materials and fork shapes give different pitches; Titanium, for example, can produce a bright, lively ring. The effect is as much about sound as about touch.
What to look for
Consider whether you want a pronounced ring, since resonant pieces are usually more noticeable in quiet places. Check what the fork is made of and whether forks or tines can be swapped to change pitch. Avoid bending or dropping the fork, which can change its tone.
是什么
音叉共振（Tuning-Fork Resonance）是由音叉形零件在被敲击或释放时振动而产生的反馈。和乐器音叉一样，它的形状、长度和材质决定音高以及余音长短。在 EDC 中，内置的音叉或叉片可以把每一次动作变成清亮的鸣响。
上手感受
你听到和感受到的不是沉闷的咔哒，而是会回荡、渐弱的共鸣音，手指上常有轻微振动。不同材质和音叉形状带来不同音高，例如钛能发出明亮灵动的鸣响。这种效果既关乎声音，也关乎触感。
选购要点
考虑你是否想要明显的鸣响，共鸣类作品在安静场合通常更引人注意。确认音叉材质，以及音叉或叉片能否更换来改变音高。避免弯折或摔落音叉，以免改变音色。
