Description

Headphone device for reducing environmental noise and portable listening practice device

Technical Field

The invention relates to the technical field of in-ear headphones, in particular to a headphone device for reducing environmental noise and a portable listening practice device.

Background Art

Earphones are a pair of conversion units that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers close to the ears. Existing noise reduction earphones mainly include active noise reduction and passive noise reduction. Active noise reduction earphones are larger in size and more complex in structure, so passive noise reduction earphones are more common. Passive noise reduction earphones are generally in the form of in-ear earplugs. Generally, replaceable rubber plugs of different diameters are used for different ear canal sizes. The desired effect can be achieved by replacing the plugs.

Some earphone devices use deformable devices to change the outer diameter of the plug to achieve a sound insulation effect, such as the Chinese patent: earphone device (CN 101911719 B). By actuating the adjustable component, the compressible material can be decompressed and stretched to be inserted into the wearer's ear, and the compressible material can be compressed to widen or expand to form a sufficient seal on the wearer's ear canal area. The earphone device of this patent has two main problems. The first problem is that since the earphone needs to actuate the adjustable component, such as pulling, twisting or rotating a part of the adjustable component, the adjustable component structure needs to be very compact due to the small size of the earphone. At the same time, the ear space is very small, so it is very difficult to operate the adjustable component with fingers, and the practicality is not high. The second problem is that although this type of earphone device can adjust the adjustable component to expand the outer diameter of the compressible material, it is difficult to arrange the channel for sound transmission.

Summary of the invention

In order to solve the above problems, the present invention provides an earphone device for reducing environmental noise. The earphone device can adjust the outer diameter of the plug relatively simply and is easy to operate.

To achieve the above object, the technical solution adopted by the present invention is:

DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in combination with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

In order to solve the problems in the prior art that it is difficult to operate the adjustable component 20 of the headphone device and it is difficult to arrange the channel for sound transmission, the present embodiment proposes a headphone device for reducing environmental noise from a practical and novel perspective. As shown in FIG1 , the front portion of the headphone device in the present embodiment is a deformable structure 10, the rear portion of the deformable structure 10 is provided with a positioning member 30, the tail portion of the positioning member 30 has an adjustable component 20, a portion of the adjustable component 20 is exposed from the deformable structure 10, and a portion of the adjustable component 20 is placed inside the deformable structure 10.

As shown in FIG. 2 , the deformable structure 10 has a generally cylindrical outer contour, and the front end of the deformable structure 10 is a frustum-shaped introduction structure 13, which can facilitate the placement of the deformable structure 10 into the ear canal. The deformable structure 10 has a first inner cavity 12 inside, and the first inner cavity 12 is a conical cavity. The axis of the first inner cavity 12 is the same as that of the deformable structure 10, and the diameter of the first inner cavity 12 gradually decreases from the back to the front. In other embodiments, the first inner cavity 12 and the axis of the deformable structure 10 can have different axes, so that the adjustable member 20 can be offset, which is convenient for operating the adjustable member 20.

As shown in FIG. 2 , the position of the positioning member 30 is only exemplified, and the shape of the positioning member 30 is not limited. The positioning member 30 can be made into an ergonomic shape, such as an ellipsoid. Alternatively, the interior of the positioning member 30 is made of a hard material, and the periphery of the positioning member 30 is made of a sponge material, so as to be mounted in the auricle.

The adjustable member 20 is generally barbell-shaped, and the deformable structure 21 and the operating structure 23 are both spherical. The deformable structure 21 and the operating structure 23 are connected by a middle connecting member 22, which can be rod-shaped or tubular. A fourth through hole 31 is provided at the center of the positioning member 30 corresponding to the first inner cavity 12. The diameter of the fourth through hole 31 is slightly larger than the deformable structure 21. When the deformable structure 21 is placed in the first inner cavity 12, the deformable structure 21 will not fall out of the first inner cavity 12. At the same time, the inner annular surface of the fourth through hole 31 cooperates with the outer annular surface of the connecting member 22 to guide the moving direction of the adjustable member 20.

Therefore, when the earphone device is used, the deformable structure 10 is first placed into the ear canal, and then the operating structure 23 is pushed by the fingertips to push the deformable structure 10 to the expected depth. At this time, the positioning piece 30 contacts the inner wall of the cavum concha and abuts against the opening of the ear canal. At the same time, the adjustable component 20 moves toward the front end of the deformable structure 10, and the deformable structure 21 moves toward the front end of the first inner cavity 12, and the deformable structure 21 squeezes the inner wall of the first cavity, so that the deformable structure 10 expands its outer contour and generates a seal on the ear canal.

Preferably, the front end of the deformable structure 10 is provided with a first through hole 11, and the function of the first through hole 11 is to reduce the air pressure when the deformable structure 21 is pushed forward, and the air in the first inner cavity 12 can enter the ear canal through the advancement of the deformable structure 21. The second function of the first through hole 11 is to serve as a channel for sound conduction. When the first through hole 11 serves as a channel for sound conduction, the diameter of the first through hole 11 can be appropriately enlarged, or the shape of the first through hole 11 can be changed, such as a trumpet shape, and the trumpet-shaped first through hole 11 can change the sound field.

As shown in FIG3 , an expanded diameter section 14 is provided near the tail portion of the first inner cavity 12. Since the deformable structure 21 in this embodiment is spherical, the inner wall of the expanded diameter section 14 is a part of the sphere that matches the outer shape of the deformable structure 21. At this time, the deformable structure 21 can be retained in the expanded diameter section 14 during the process of pushing the deformable structure 10 into the ear canal. Only when the positioning member 30 contacts the human tissue at the ear canal opening will the deformable structure 21 come out of the expanded diameter section 14, thereby changing the outer contour of the deformable structure 10.

As shown in FIG4 , since the deformable structure 10 is preferably a sponge cover, the sponge cover has poor durability. During the aging test, the deformable structure 10 is damaged after repeated contact with the deformable structure 21. Therefore, a cylindrical cavity is formed inside the deformable structure 10, and a spinal tube-shaped deformable attachment 15 is placed in the cavity. The deformable attachment 15 is made of silicone material, which has better wear resistance. At the same time, the deformable attachment 15 made of silicone material needs to have greater elasticity and better friction with the deformable structure 21.

Preferably, a friction member 32, such as a rubber tube sleeve, is provided on the inner annular surface where the fourth through hole 31 is located. The friction member 32 maintains contact with the connecting member 22, adding a certain friction force. The advantage is that when the deformable structure 10 is pushed into the ear canal, the deformable structure 21 will only move forward when the positioning member 30 contacts the human tissue at the ear canal opening, thereby changing the outer contour of the deformable structure 10.

As shown in FIG5 , the deformable structure 21 has a cavity inside, the deformable structure 21 connecting structure is a tubular body, the deformable structure 21 has a second through hole 211 at the front end and the first through hole 11, and the deformable structure 21 has a second through hole 211 at the corresponding connecting structure, so that the deformable structure 21 and the connecting structure cavity are connected. The internal cavity of the deformable structure 21 and the second cavity 221 in the connecting member 22 can be used as a cavity for guiding sound.

In one embodiment, a sound guide tube 222 is provided on the side of the connecting member 22 near the tail, and the sound guide tube 222 is connected to the second inner cavity 221, so that sound can be transmitted into the second inner cavity 221 through the sound guide tube 222, and enter the ear canal through the third through hole 212, the second through hole 211 and the first through hole 11.

As shown in FIG. 6 , in a feasible embodiment, the deformable structure 21 and the sound guide tube 222 can also be used as an integrated part, and a sound generating unit is built into the operating structure 23 .

The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the protection scope of this patent.
