Portable earplug

Abstract

The invention discloses a portable earplug comprising an invisible handle and an earplug, wherein a sound transfer channel is arranged in the invisible handle and the earplug, a magnetic pole and a magnetic latching relay are arranged on the edge of the sound transfer channel, a circuit board and a control button are arranged on the invisible handle, and the control button is connected with the magnetic latching relay. A denoising membrane in the earplug is expanded along with increasing of noise, the area of the cross section of the sound transfer channel is changed, and the noise is prevented from entering an ear of a user; when the user enters an environment with relatively large noise, the user can press down the control button to generate a magnetic field around the magnetic pole, sothat the magnetic pole rotates to plug the sound transfer channel and prevent noise from entering the ear of the user; when the user needs to listen to the other people, the user can press down the control button once again, the magnetic field around the magnetic pole disappears, the magnetic pole rotates to the original site, the smoothness of the sound transfer channel is kept, and thus the usercan listen to the other people normally; when someone calls the name of the user, the earphone plays the sound of the caller to the user, and the condition that the user can reply in time is ensured.
