Compared with the prior art, the utility model discloses following beneficial effect has:

the underwater sound can be detected and transmitted to ears, and the ears have little discomfort. The small end of the inner frame body is provided with the vibrating diaphragm, so that sound waves are attenuated less when passing through the earplug, and sound signals can be heard well. When the earplug is inserted into an ear canal, air in the ear canal is compressed, and if high-pressure air in the ear canal is not released, eardrum discomfort is caused; through setting up the stifled pipe of one-way release, the high-pressure gas in the duct overcomes the spring force and backs down the closure plate to high-pressure gas is released. The position of the adjusting plug in the tube body can be adjusted through rotation, and the tightness of the opening of the tube body can be pressed by the adjusting plug plate.

The technical principle of the scheme is as follows: the inner frame body is of a cone frustum structure, the elastic filling layer is covered outside the inner frame body, and when the earplug is plugged into the auditory canal, the elastic filling layer is attached to the auditory canal under the action of elasticity, so that the effect of preventing water from entering the auditory canal is achieved; by the arranged vibrating diaphragm, after the earplug is worn, external sound waves can still be transmitted to the eardrum in a relatively small attenuation manner; through the stifled pipe of one-way release that sets up, when inserting the earplug into the ear, form the high atmospheric pressure in the ear, the stifled board that the spring was held is backed up to the high atmospheric pressure, and too high air pressure in the release ear, but water can not pass through in getting into the duct from another direction.

Preferably, still be provided with first annular groove and second annular groove on the inner frame body outer wall, be provided with first snap ring on the first annular groove, first snap ring will the elasticity filling layer tighten on the first annular groove, be provided with the second snap ring on the second annular groove, the second snap ring will the elasticity filling layer tighten on the second annular groove.

The elastic filling layer is bound on the inner frame body through the two clamping rings, so that the elastic filling layer is prevented from falling off from the inner frame body in use.

Furthermore, the first snap ring is provided with an opening, and a first mounting hole and a second mounting hole are respectively formed in two ends of the opening of the first snap ring.

The two clamp columns of the nipper pliers are respectively inserted into the first mounting hole and the second mounting hole, and the first clamp ring can be taken down or mounted on the first annular groove by separating or folding the two clamp columns.

Preferably, a rubber pad is further disposed between the blocking plate and the end of the pipe body.

The rubber pad can play a better sealing role.

Preferably, a handle is further arranged on the turned edge.

The handle facilitates insertion and extraction of the earplug from the ear.

Preferably, an elastic hanging rope is further arranged on the turned edge.

The earplug is hung on the root of the ear by the elastic hanging rope, so that the earplug is firmer.

Further, the elastic hanging rope is a rubber band.

Preferably, the elastic filling layer is made of silica gel.
