摘要：

An earplug includes a sleeve, a resonance tube, and a tip. The sleeve has a plurality of slits, and the resonance tube is connected between the sleeve and the tip. When the sleeve is pressed to deform, the slits are opened to allow sound to enter the sleeve, and pass through the resonance tube and the tip.
