The present disclosure relates to an earplug product, and in particular to an in-ear earplug structure.
Earplugs are generally used in earphones or noise-proof products. The structure of an existing in-ear earplug is generally to set two or three umbrella-shaped rubber sleeves on a hard cylindrical tube. With the matching of the umbrella-shaped rubber sleeves and ears, noise reduction function is realized, but because the cylindrical tube at the center is generally made of hard plastic, when the earplug is inserted into an ear canal, the cylindrical tube will obviously bring a hard feeling, which will cause discomfort to wear, especially when used for a long time, the discomfort is more obvious. In addition, such a structure of combination of hard parts and soft parts has an unsatisfactory sound insulation effect, so it cannot meet the noise reduction requirements.
The technical problem to be solved by the present disclosure is to provide an in-ear earplug structure that is comfortable to wear, better in sound insulation, easy to manufacture, and low in cost, in view of the deficiencies of the prior art.
In order to solve the above technical problem, the technical solution used by the present disclosure is as follows.
An in-ear earplug structure comprises a hollow support body, wherein a sound hole is opened at a front end of the support body, an outer side of the support body is provided with at least two soft umbrella-shaped plug bodies, the support body and the umbrella-shaped plug bodies are integrally molded, a speaker unit is provided in the support body, a preset spacing is formed between the speaker unit and the sound hole, a rear sound cavity is formed in the support body, the rear sound cavity is located on the rear side of the speaker unit, and a through hole which is in communication with the rear sound cavity is opened at a side part of the support body.
Preferably, the support body and the umbrella-shaped plug bodies are molded by injection using soft rubber materials.
Preferably, the cross section of the umbrella-shaped plug body is oval.
Preferably, two umbrella-shaped plug bodies are formed on the outer side of the support body, and the sizes of the two umbrella-shaped plug bodies increase sequentially from front to back.
Preferably, an inner wall of the support body is formed with an inwardly protruding annular flange.
In the in-ear earplug structure disclosed by the present disclosure, the support body and the umbrella-shaped plug bodies are arranged as an integral structure, such that the main part of the earplug is a soft structure. Meanwhile, the position of the speaker unit is moved back, such that there is a certain distance between the speaker unit and the sound hole. Based on the above structure, when the earplug is worn on an ear, the hard feeling caused by the earplug is greatly reduced, and the wearing comfort is effectively improved. Also, this makes the umbrella-shaped plug body better fit an ear canal, thereby improving the sound insulation effect. In addition, the support body and the umbrella-shaped plug bodies can be integrally processed and molded, making the earplug easier to manufacture and low in cost, which satisfies the needs of users and the market well.
The following describes the present disclosure in more detail with reference to the drawings and embodiments.
The present disclosure discloses an in-ear earplug structure. As shown in
In the above structure, the support body 1 and the umbrella-shaped plug bodies 3 are arranged as an integral structure, such that the main part of the earplug is a soft structure. Meanwhile, the position of the speaker unit 4 is moved back, such that there is a certain distance between the speaker unit 4 and the sound hole 2. Based on the above structure, when the earplug is worn on an ear, the hard feeling caused by the earplug is greatly reduced, and the wearing comfort is effectively improved. Also, this makes the umbrella-shaped plug body 3 better fit an ear canal, thereby improving the sound insulation effect. In addition, the support body 1 and the umbrella-shaped plug bodies 3 can be integrally processed and molded, making the earplug easier to manufacture and low in cost, which satisfies the needs of users and the market well.
In order to facilitate production and manufacturing, in this embodiment, the support body 1 and the umbrella plug bodies 3 are molded by injection using soft rubber materials.
In this embodiment, the cross section of the umbrella-shaped plug body 3 is oval. The oval structure can make the umbrella plug body 3 better fit the user's ear canal, thereby further improving the sound insulation and noise reduction effect.
As a preferred structure, two umbrella-shaped plug bodies 3 are formed on the outer side of the support body 1, and the sizes of the two umbrella-shaped plug bodies 3 increase sequentially from front to back.
In this embodiment, an inner wall of the support body 1 is formed with an inwardly protruding annular flange 7. The annular flange 7 can strengthen the support body 1 internally.
In other embodiments, as shown in
In other embodiments, as shown in
The above embodiments are merely preferred embodiments of the present disclosure but not intended to limit the present disclosure, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present disclosure should be included within the scope of protection of the present disclosure.
