Description

Technical Field

[0001] This invention relates to the field of headphone technology, and in particular to an ear clip-on hearing aid that can adjust the distance between the speaker's sound outlet and the external auditory canal. Background Technology

[0002] Hearing aids are hearing-assistive devices, small amplifiers that amplify sounds that were previously inaudible. Utilizing the residual hearing of the hearing-impaired individual, they deliver sound to the auditory center of the brain, allowing the person to perceive the sound. They bring great convenience to the hearing-impaired. Based on their usage, hearing aids are classified into box-type, eyeglass-type, hair clip-on, behind-the-ear, in-the-ear, in-the-canal, and fully-in-the-canal hearing aids. In-the-ear hearing aids further include clip-on hearing aids.

[0003] In the prior art, the ear clip hearing aid includes a clamping unit, an in-ear unit, and a bridge. The bridge connects the clamping unit and the in-ear unit. The clamping unit and the in-ear unit can be clamped on the ear. The microphone of the ear clip body picks up the sound and transmits the sound to the ear through the speaker. However, the ear clip hearing aid in the prior art still has the following disadvantages: (1) The surface of the ear clip body of the ear clip hearing aid in the prior art is relatively hard and has little elasticity. After wearing it on the ear for a long time, the user will feel the clamping pain and discomfort. In particular, the ear shape of different users is very different, and the shape of the ear clip body is difficult to match the inner ear shape of different users; (2) The size of the in-ear unit of the ear clip hearing aid in the prior art is fixed and cannot meet the needs of supporting the concha cavity of different users with different sizes. Furthermore, the distance between the speaker outlet hole of the in-ear unit and the external auditory canal cannot be adjusted. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an ear clip-on hearing aid that is comfortable to wear, can support different sizes of conchae for different users, and allows adjustment of the distance between the speaker outlet and the external auditory canal, addressing the shortcomings of the prior art. To solve the above-mentioned technical problems, the present invention provides an ear clip-on hearing aid that can adjust the distance between the speaker's sound outlet and the external auditory canal, including a clamping unit, an in-ear unit, and a bridge. The bridge connects the clamping unit and the in-ear unit. The in-ear unit includes a rigid inner shell, a speaker, a silicone outer shell without ear wings, and a silicone outer shell with ear wings. The speaker is installed inside the rigid inner shell. The front end of the rigid inner shell has a speaker sound outlet, and the speaker's sound output direction faces the speaker sound outlet. Either the silicone outer shell without ear wings or the silicone outer shell with ear wings is detachably fitted outside the rigid inner shell. The front ends of the silicone outer shell without ear wings and the silicone outer shell with ear wings respectively have sound outlet holes corresponding to the speaker sound outlet. The rear end of the silicone outer shell without ear wings does not have an ear wing, and the rear end of the silicone outer shell with ear wings is connected to a rearward-extending ear wing.

[0005] The beneficial effects of the technical solution of the present invention are: (1) Since the in-ear unit of the present invention includes a hard inner shell, a silicone shell without ear wings, and a silicone shell with ear wings, and either the silicone shell without ear wings or the silicone shell with ear wings can be detachably fitted outside the hard inner shell, the present invention can utilize the softness of the material of the silicone shell without ear wings or the silicone shell with ear wings to improve the user's wearing comfort; (2) Since both the silicone shell without ear wings and the silicone shell with ear wings adopt a detachable structure, the silicone shell without ear wings and the silicone shell with ear wings can be used interchangeably. When the user's concha is small, the silicone shell without ear wings can be installed outside the hard inner shell; when the user's concha is large, the silicone shell with ear wings can be installed outside the hard inner shell; (2) Furthermore, since both the wingless and winged silicone shells of this invention are detachable, when the same user wears an ear clip-on hearing aid, the distance between the speaker hole of the rigid inner shell and the sound outlet of the wingless silicone shell and the external auditory canal is relatively far when the in-ear unit uses a wingless silicone shell; when the in-ear unit uses a winged silicone shell, under the support of the ear wing, the in-ear unit will move forward towards the external auditory canal as a whole, and the distance between the speaker hole of the rigid inner shell and the sound outlet of the wingless silicone shell and the external auditory canal is relatively close, resulting in better sound transmission. Therefore, this invention can adjust the distance between the speaker hole and the sound outlet of the in-ear unit and the external auditory canal by changing the wingless or winged silicone shell.

[0006] In a preferred embodiment of the present invention, the posterior side of the ear wing is provided with an arcuate surface adapted to the concha cavity of the human ear, and the arcuate surface of the ear wing smoothly transitions to the surface of the silicone shell with the ear wing. When wearing a clip-on hearing aid, this structure of the ear wing allows it to be precisely positioned within the concha cavity of the human ear, greatly improving the stability of the fit, while distributing pressure to the cartilage area, avoiding pain caused by single-point pressure; the smooth, stepless transition between the arcuate surface of the ear wing and the silicone shell with the ear wing eliminates the sharp edges between the ear wing and the silicone shell with the ear wing, ensuring a seamless fit with the skin.

[0007] In a preferred embodiment of the invention, the ear wing and the sound outlet face opposite directions, with the ear wing facing the rear of the silicone outer shell with ear wing, and the sound outlet facing the front of the silicone outer shell with ear wing. When wearing a clip-on hearing aid, because the ear wing and the sound outlet face opposite directions, the ear wing, under its support, will push the speaker outlet of the rigid inner shell and the sound outlet of the silicone outer shell without ear wing towards the external auditory canal.

[0008] In a preferred embodiment of the present invention, the ear wing and the silicone shell with ear wings are integrally formed and connected. The ear wing has through holes, and the number of through holes is 2 to 4. The ear wing and the silicone shell with ear wings of the present invention are integrally formed from silicone, eliminating the joint seams caused by bonding or secondary assembly. This not only completely eliminates the risk of delamination or loosening during long-term use, but also allows the silicone molecular chains to form a continuous whole during the cross-linking process, enabling uniform load transfer and strong tear resistance. The ear wing of the present invention has 2 to 4 through holes, allowing for more controllable bending deformation when inserted into the concha, adapting to different ear sizes and reducing pressure on the cartilage. Simultaneously, the material removal resulting from the through holes also achieves weight reduction, reducing the feeling of heaviness when wearing the ear.

[0009] In a preferred embodiment of the present invention, two silicone ear-wing shells are provided, wherein the distance between the front and rear ends of the ear wing in one ear-wing shell is greater than that in the other ear-wing shell. By providing two types of silicone ear-wing shells, the present invention can further adjust the distance between the speaker outlet of the in-ear unit and the external auditory canal. When the distance between the front and rear ends of the ear wing is smaller, the distance between the speaker outlet and the sound outlet of the in-ear unit and the external auditory canal is greater; when the distance between the front and rear ends of the ear wing is larger, the distance between the speaker outlet and the sound outlet of the in-ear unit and the external auditory canal is closer, resulting in better sound transmission.

[0010] In a preferred embodiment of the present invention, the surface shapes of the wingless silicone shell and the winged silicone shell are adapted to the concha cavity of the human ear. When wearing the ear clip-on hearing aid, the speaker outlet and the sound outlet can extend into the external auditory canal. The shell surface adapts to the concha cavity, achieving surface contact support instead of point pressure. Combined with the clamping force of the ear clip, it ensures painless wear for extended periods and utilizes the natural concave structure of the concha cavity to form an anti-dislodgement self-locking mechanism, improving stability during daily activities.

[0011] In a preferred embodiment of the present invention, the upper ends of both the earless and ear-winged silicone outer shells are provided with mounting holes. The rigid inner shell can be inserted into or removed from the earless or ear-winged silicone outer shell through the mounting holes. The upper end of the rigid inner shell is provided with an upwardly protruding boss. When the rigid inner shell can be inserted into the earless or ear-winged silicone outer shell through the mounting holes, the inner wall of the mounting hole fits onto the outer edge of the boss, and the inner wall of the sound outlet hole fits onto the outer edge of the speaker sound outlet hole. The present invention, by providing mounting holes, facilitates the installation and removal of the rigid inner shell. Simultaneously, the inner wall of the mounting hole fits onto the outer edge of the boss, and the inner wall of the sound outlet hole fits onto the outer edge of the speaker sound outlet hole. This is a dual-point coaxial positioning design, ensuring that the two fitting points are naturally aligned during assembly, guaranteeing strict alignment between the speaker and the sound outlet channel, and avoiding sound attenuation or distortion due to misalignment.

[0012] In a preferred embodiment of the present invention, a bridge mounting hole is provided within the boss portion of the rigid inner shell, and one end of the bridge portion is inserted into the bridge mounting hole. The present invention integrates the bridge mounting hole into the boss portion, with the mounting hole directly located within the boss portion. This allows the fixing point of the bridge portion and the assembly positioning point of the outer shell to share a single structural area. This integrated design reduces the need for additional fixing brackets. Simultaneously, the bridge portion, as part of the rigid inner shell, is inserted and fixed, forming a rigid force transmission path from the inner shell to the bridge portion.

[0017] Figure 5 This is a schematic diagram of the structure of an ear clip-on hearing aid with a silicone shell and ear wings worn on an earmold. Detailed Implementation

[0018] The structural and working principles of the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 and Figure 2As shown, the present invention provides an ear clip-on hearing aid with adjustable distance between the speaker outlet and the external auditory canal, including a clamping unit 1, an in-ear unit 2, and a bridge 3. The bridge 3 connects the clamping unit 1 and the in-ear unit 2. The in-ear unit 2 includes a rigid inner shell 21, a speaker 22, a silicone outer shell 23 without ear wings, and a silicone outer shell 24 with ear wings. The speaker 22 is installed inside the rigid inner shell 21, and the front end of the rigid inner shell 21 is provided with a speaker outlet 211. The sound output direction of the speaker 22 faces the speaker sound output hole 211; either the earless silicone shell 23 or the ear-winged silicone shell 24 is detachably fitted outside the rigid inner shell 21. The front ends of the earless silicone shell 23 and the ear-winged silicone shell 24 are respectively provided with sound output through holes 25 corresponding to the speaker sound output hole 211. The rear end of the earless silicone shell 23 does not have ear wings, and the rear end of the ear-winged silicone shell 24 is connected to a rearwardly extending ear wing 26.

[0020] like Figure 3 The diagram shows the structure of a human ear mold. The auricle includes an antihelix 4, a crus of the helix 5, a tragus 6, an antitragus 7, and an external auditory canal 9. The antihelix 4, a crus of the helix 5, a tragus 6, and an antitragus 7 together form a concha cavity 8. The outer end of the external auditory canal 9 is located inside the tragus 6. When the ear clip-on hearing aid of this invention is worn on the ear, the clip unit 1 is located on the back of the auricle, and the in-ear unit 2 is located inside the concha cavity 8. The speaker outlet 211 and the sound outlet through-hole 25 of the in-ear unit 2 face the external auditory canal 9. Since the in-ear unit 2 includes a rigid inner shell 21, a silicone outer shell 23 without ear wings, and a silicone outer shell 24 with ear wings, and either the silicone outer shell 23 without ear wings or the silicone outer shell 24 with ear wings can be detachably fitted outside the rigid inner shell 21, this invention can utilize the softness of the material of either the silicone outer shell 23 without ear wings or the silicone outer shell 24 with ear wings to improve the user's wearing comfort. Because both the wingless silicone shell 23 and the winged silicone shell 24 of this invention have a detachable structure, they can be used interchangeably. When the user's concha 8 is small, the wingless silicone shell 23 can be installed outside the rigid inner shell 21; when the user's concha 8 is large, the winged silicone shell 24 can be installed outside the rigid inner shell 21. Furthermore, because both the wingless silicone shell 23 and the winged silicone shell 24 have a detachable structure, the same user can use them interchangeably when wearing an ear clip-on hearing aid. Figure 4 When the in-ear unit 2 uses a wingless silicone shell 23, the speaker outlet 211 of the rigid inner shell 21 and the sound outlet 25 of the wingless silicone shell 23 are far from the external auditory canal 9; see Figure 5When the in-ear unit 2 uses a silicone shell 24 with ear wings, under the support of the ear wings 26, the in-ear unit 2 will move forward towards the external auditory canal 9 of the human ear. The speaker outlet 211 of the hard inner shell 21 and the sound outlet 25 of the silicone shell 23 without ear wings are closer to the external auditory canal 9 of the human ear, resulting in better sound transmission. It can be seen that the present invention can achieve the purpose of adjusting the distance between the speaker outlet and the sound outlet of the in-ear unit 2 and the external auditory canal by replacing the silicone shell 23 without ear wings or the silicone shell 24 with ear wings.

[0021] like Figure 1 and Figure 2 As shown, the rear side of the ear wing 26 is provided with an ear wing arc surface 261 that conforms to the concha cavity 8 of the human ear. The ear wing arc surface 261 smoothly transitions to the surface of the silicone shell 24 with ear wing. When wearing a clip-on hearing aid, this structure of the ear wing 26 allows the ear wing 26 to be precisely positioned within the concha cavity 8 of the human ear, greatly improving the stability of the fit, while distributing pressure to the cartilage area, avoiding pain caused by single-point pressure; the smooth, stepless transition between the ear wing arc surface 261 and the silicone shell 24 with ear wing eliminates the sharp edges between the ear wing 26 and the silicone shell 24 with ear wing, ensuring a seamless fit with the skin.

[0022] like Figure 1 and Figure 2 As shown, the ear wing 26 and the sound outlet 25 face opposite directions; the ear wing 26 faces the rear of the silicone shell 24 with ear wings, and the sound outlet 25 faces the front of the silicone shell 24 with ear wings. When wearing a clip-on hearing aid, because the ear wing 26 and the sound outlet 25 face opposite directions, therefore, see... Figure 5 With the support of the ear wing 6, the speaker outlet 211 of the hard inner shell 21 and the sound outlet 25 of the silicone outer shell 23 without ear wings will be pushed into the external auditory canal 8 of the human ear.

[0023] like Figure 1 and Figure 2 As shown, the ear wing 26 is integrally formed and connected to the silicone shell 24 with ear wings. The ear wing 26 has through-holes 262, and the number of through-holes 262 is 2 to 4. The ear wing 26 and the silicone shell 24 with ear wings of this invention are integrally formed from silicone, eliminating the joint seams caused by bonding or secondary assembly. This not only completely eliminates the risk of delamination or loosening during long-term use, but also allows the silicone molecular chains to form a continuous whole during cross-linking, enabling uniform load transfer and strong tear resistance. The ear wing 26 of this invention has 2 to 4 through-holes 262, allowing for more controllable bending deformation when inserted into the concha 8, adapting to different auricular sizes and reducing pressure on the cartilage. Simultaneously, the material removal resulting from the through-holes 262 also achieves weight reduction, reducing the feeling of heaviness during wear.

[0024] like Figure 1 and Figure 2 As shown, there are two silicone shells 24 with ear wings. Figure 2 The distance between the front and rear ends of the ear wings of the silicone shell 24 with ear wings shown in part (a) is greater than [missing information]. Figure 2 The distance between the front and rear ends of the ear wing of the silicone shell 24 with ear wings shown in part (b) is as follows. By providing two types of silicone shells 24 with ear wings, this invention can further adjust the distance between the speaker outlet and the sound outlet of the in-ear unit 2 and the external auditory canal. When the distance between the front and rear ends of the ear wing is small, the distance between the speaker outlet and the sound outlet of the in-ear unit 2 and the external auditory canal will be greater. When the distance between the front and rear ends of the ear wing is large, the distance between the speaker outlet and the sound outlet of the in-ear unit 2 and the external auditory canal will be closer, resulting in better sound transmission.

[0025] like Figures 1-5 As shown, the surface shapes of the silicone shell 23 without ear wings and the silicone shell 24 with ear wings are adapted to the concha cavity 8 of the human ear. When wearing the ear clip-on hearing aid, the speaker outlet 211 and the sound outlet 25 can extend into the external auditory canal 9 of the human ear. The surface of the shell is adapted to the concha cavity 8, realizing surface contact support instead of point pressure. Combined with the clamping force of the ear clip, it not only ensures painless wear for a long time, but also utilizes the natural concave structure of the concha cavity 8 to form an anti-dislodgement self-locking mechanism, improving stability during daily activities.

[0026] like Figure 1 and Figure 2 As shown, the upper ends of the earless silicone shell 23 and the ear-winged silicone shell 24 are respectively provided with mounting holes 27. The rigid inner shell 21 can be inserted into the earless silicone shell 23 or the ear-winged silicone shell 24 through the mounting holes 27 or removed from the mounting holes 27. The upper end of the rigid inner shell 21 is provided with an upwardly protruding boss 212. When the rigid inner shell 21 can be inserted into the earless silicone shell 23 or the ear-winged silicone shell 24 through the mounting holes 27, the inner wall of the mounting holes 27 is fitted onto the outer edge of the boss 212, and the inner wall of the sound outlet hole 25 is fitted onto the outer edge of the speaker sound outlet hole 211. The present invention provides a mounting hole 27, which allows for easy installation and removal of the rigid inner shell 21. At the same time, the inner wall of the mounting hole 27 fits around the outer edge of the boss portion 212, and the inner wall of the sound outlet hole 25 fits around the outer edge of the speaker sound outlet hole 211. This is a dual-point coaxial positioning design, which ensures that the two fitting points are naturally aligned during assembly, ensuring that the speaker 22 and the sound outlet channel are strictly aligned, thus avoiding sound attenuation or distortion caused by misalignment.

[0027] like Figure 1 and Figure 2As shown, a bridge mounting hole 213 is provided within the boss portion 212 of the rigid inner shell 21, and one end of the bridge portion 3 is inserted into the bridge mounting hole 213. This invention integrates the bridge mounting hole 213 into the boss portion 212, directly setting the mounting hole within the boss portion 212. This allows the fixing point of the bridge portion 3 and the assembly positioning point of the outer shell to share a structural area. This integrated design reduces the need for additional fixing brackets. Simultaneously, the bridge portion 3, as part of the rigid inner shell 21, is inserted and fixed, forming a rigid force transmission path from the inner shell to the bridge portion 3.

[0028] The above description is merely a preferred embodiment of the present invention. Any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical solution of the present invention shall fall within the scope of the technical solution of the present invention.
