Description

Anti-noise earplugs

technical field

The utility model relates to an earplug, in particular to a noise-proof earplug capable of reducing noise.

Background technique

With the development of the times, environmental noise has become an inevitable pollution. Especially in some specific workplaces, noise pollution is very serious, such as airports, machine workshops, etc. Noise not only damages people's body organs, but also disturbs people's psychology to a certain extent, reduces people's work efficiency, and in severe cases will lead to unnecessary consequences.

A utility model patent named "Earplug" with a notification number of CN 2493188 Y and an announcement date of 2002.05.29 provides a kind of earplug, which is made of elastic polymer material integrally. There is a cylinder integrally formed on the side of the pad, and the middle section of the cylinder is provided with a plugging part in the shape of a soft sheet, so that the earplug is not easy to fall out of the ear and is not easy to cause pain when it is plugged in, but this kind of earplug cannot effectively prevent it. The harm of noise to the human body.

Utility model content

The purpose of this utility model is to solve the problem that the noise causes harm to the human body in an environment seriously affected by noise, and to provide a new type of device that can adjust the intensity of external noise and adjust the pressure inside and outside the ear canal in real time to prevent the human ear from being hurt. Noise-canceling earplugs.

In order to realize the above-mentioned purpose of the invention, the utility model adopts the following technical solutions:

An anti-noise earplug, comprising an earplug head, a fixing buckle and a noise reduction device, the earplug head is hollow, the noise reduction device is fixedly connected to the rear end of the earplug head, and the fixing buckle is fixedly connected to the middle part of the earplug head.

The utility model can reduce the external noise to a suitable level according to the requirement by connecting the sound-absorbing device at the back of the earplug head, and protect people's ears to a certain extent.

As a preferred solution, the noise reduction device includes a shell, in which a sound filter is arranged, and a sound inlet, a switch and a range adjuster are arranged on the shell, and the switch and the range adjuster are respectively connected with the sound filter. The sound filter filters the sound, the sound inlet is used to capture external sound, the switch controls the switch of the sound filter, and the range adjuster adjusts the filtering degree of the sound filter.

As a preferred solution, an air pressure regulator is arranged inside the earplug head, and the air pressure regulator is located in the cavity of the earplug head and glued to the earplug head. Under normal circumstances, the pressure on both sides of the eardrum of the human ear is the same. When there are severe changes, such as those experienced by airplane passengers during takeoff and landing, there is a difference in air pressure between the middle ear and the external environment. When there is a pressure difference between the middle ear and the external environment, the air pressure regulator can reduce the pressure change rate of the external auditory canal, thereby avoiding ear pain caused by excessive pressure difference on both sides of the tympanic membrane.

As a preferred solution, the fixing buckle is glued to the head of the earplug.

As a preferred solution, the noise reduction device is glued to the head of the earplug.

As a preferred solution, the shape of the front end of the earplug head matches the ear hole.

As a preferred solution, the fixing buckle is arc-shaped, and the fixing buckle matches the auricle. The curved buckle can fix the earplugs on the ear.

As a preferred solution, the air pressure regulator is cylindrical, and the cylindrical shape is provided with a plurality of holes passing through both ends of the cylinder. The air pressure regulator can adjust the large change rate of the external auditory canal and the external pressure to prevent discomfort to the human ear.

Due to the adoption of the above-mentioned technical solution, the beneficial effect of the utility model is that the new anti-noise earplug can reduce the external noise to an appropriate level as required, and can adjust the pressure balance between the outside and the ear canal in real time to prevent the ear from being damaged.

Description of drawings

Fig. 1 is a kind of structural representation of the utility model,

Fig. 2 is a structural schematic diagram of an air pressure regulator of the present invention.

In the figure: 1 ear plug head, 2 fixed buckle, 3 noise reduction device, 4 sound filter, 5 sound inlet, 6 switch, 7 range regulator, 8 air pressure regulator, 9 holes.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, a noise-proof earplug includes an earplug head 1, a fixing buckle 2 and a noise reduction device 3. The shape of the front end of the earplug head 1 matches the ear hole, and an air pressure regulator made of ceramic material is arranged inside the earplug head 1. 8 to adjust the pressure change rate between the ear canal and the external environment, and the air pressure regulator 8 is glued to the inner wall of the earplug head 1. As shown in Figure 2, the air pressure regulator 8 is cylindrical made of ceramic material, and the cylindrical shape is set There are a plurality of holes 9 through the two bottom surfaces of the cylinder, and the holes can allow air to pass through. The fixing buckle 2 is curved and matches the pinna to hang the earplugs on the ears. The noise reduction device 3 is glued to the rear end of the earplug 1, and the fixing buckle 2 is glued to the middle of the earplug 1. The noise reduction device 3 includes a casing, in which a sound filter 4 is arranged, and the casing is provided with a sound inlet 5, a switch 6 and a range adjuster 7 for adjusting the filtering volume. The sound inlet 5 is located on the front of the shell, the switch 6 and the range adjuster 7 are located on the side of the shell, and the switch 6 and the range adjuster 7 are connected to the sound filter 4 respectively.

For example, the staff at the airport, the sound of the plane taking off is very loud, so the ears of these staff need to be protected. According to the changes and needs of oneself, turn on the switch 6, and adjust the range adjuster 7 to a suitable position, and the sound filter 4 will play a role to filter the noise. Loud noises will be accompanied by air pressure changes, and the air pressure regulator 8 can protect the ears from damage by adjusting the pressure inside and outside the ear cavity.
