The second antenna 14 and the first antenna 13 can also be two separate antennas. A connection port is also provided on the shell 15 of the hearing aid body 10. The second antenna 14 and the first antenna 13 are directly welded together through the connection port to form a combined antenna. The first antenna 13 can directly extend out of the shell 15 in a direction away from the hearing aid body 10. The antenna outside the shell 15 serves as the second antenna 14. The first antenna 13 can also extend to the outside along the inner wall of the hearing aid shell 15 with multiple bending angles. The antenna extending out of the shell 15 serves as the second antenna 14. The shape of the first antenna 13 can be a straight line or a curve. The number and degree of the bending angles are not limited. Preferably, the shapes of the first antenna 13 and the second antenna 14 can be inconsistent. The specific shape can be determined in combination with product design.

[0094] Further, in some embodiments of the present embodiment, the first antenna 13 inside the hearing aid shell 15 and the second antenna 14 outside the hearing aid shell 15 can be directly welded and connected. The inner and outer widths of the first antenna 13 and the second antenna 14 can be consistent or inconsistent. When the inner and outer widths of the first antenna 13 and the second antenna 14 are consistent, the manufacturing process is simple and the cost is low. When the inner and outer widths of the first antenna 13 and the second antenna 14 are inconsistent, the width of the second antenna 14 can be appropriately narrowed under the premise of meeting the antenna performance, so that the second antenna 14 can meet the stability of the first antenna connection while ensuring the performance and aesthetics of the hearing aid. When the second antenna 14 is too thick or too long, it will affect the shielding performance. When the second antenna 14 is too thin or too short, it will increase the antenna impedance and affect the antenna performance. Preferably, in the present embodiment, the length of the second antenna outside the hearing aid shell 15 is 8-20 mm, and the width is 0.03-2 mm, which can balance the shielding performance and the antenna performance.

[0095] In some other embodiments of the present embodiment, referring to Figure 9 , Figure 10 and Figure 11The diagram shows various schematic diagrams corresponding to the indirect connection between the second antenna 14 and the first antenna 13. Figure 9 , Figure 10 and Figure 11 The dashed boxes correspond to the second antenna 14 and the first antenna 13, respectively. The second antenna 14 is located outside the housing 15, and the first antenna 13 is located inside the housing 15. (Refer to...) Figure 9 and Figure 10 The outer casing 15 has no connection port. The first antenna 13 is either close to the inner wall of the outer casing 15 or separated from the inner wall of the outer casing 15 by a certain distance. One end of the first antenna 13 is connected to the PCB motherboard 12 for signal transmission. The PCB motherboard 12 is integrated with the antenna motherboard 6. The other end of the first antenna 13 is not directly connected to the second antenna 14 and is separated by a certain distance. The in-ear hearing aid also includes a built-in high-frequency circuit for providing a high-frequency signal to the first antenna 13, so that the first antenna 13 and the second antenna 14 are indirectly coupled and connected through the high-frequency signal.

[0096] Furthermore, referring to Figure 11 To achieve better and more stable communication performance of the combined antenna, a high-dielectric-constant non-conductive spacer 16 is provided between the second antenna 14 and the first antenna 13. One end of the non-conductive spacer 16 is close to the inner wall of the housing 15, and the other end is close to the first antenna 13. The second antenna 14 is close to the outer wall of the housing 15. The second antenna 14 and the first antenna 13 are not directly connected in contact, but communicate through an indirect connection by coupling with a high-frequency signal provided by a high-frequency circuit. The high-dielectric-constant non-conductive spacer 16 between the second antenna 14 and the first antenna 13 ensures that the positions of the second antenna 14 and the first antenna 13 correspond and are fixed, thereby ensuring better and more stable communication performance when the first antenna 13 and the second antenna 14 are indirectly connected.

[0097] Optionally, refer to Figure 6 The diagram shows the structure of an in-the-ear (ITE) hearing aid. Because ITE hearing aids are very small, they are inconvenient to remove once inserted into the ear. Therefore, ITE hearing aids often have a fishing line 11 attached to the hearing aid body 10 as an external pull cable. This allows the user to pull the ITE hearing aid out of the ear canal using the fishing line 11 on the hearing aid body 10, making it convenient for the user to put on and take off the hearing aid. At least one end of the fishing line 11 is fixedly connected to the hearing aid body 10. The shape of the fishing line 11 is not limited; it can be a straight line or other shapes, for example: [refer to diagram]. Figure 13 Fishing line 11 can be a straight line; refer to Figure 20, the fish line 11 can also be a trapezoidal flat piece, which is convenient for adapting to the ear canal hearing aid design in multiple scenes. Among them, the second antenna 14 of the combined antenna can be at least partially arranged in the fish line 11, or the second antenna 14 of the combined antenna can directly serve as the fish line 11 to realize the function of taking off the ear canal hearing aid, at this time the ear canal hearing aid can also not additionally arrange the fish line 11. By arranging the second antenna at least partially in the fish line, the structure of the second antenna and the fish line is combined, which can improve the concealment of the ear canal hearing aid, while ensuring the communication function of the second antenna, better antenna concealment and aesthetics are realized.

[0098] In some embodiments of the present embodiment, the second antenna 14 is made of a metal material, and the fish line 11 is made of a non-metal material, as shown in Figure 12 , the fish line 11 can at least partially wrap the second antenna 14 exposed to the shell 15 of the ear canal hearing aid, and the specific wrapping method can include full wrapping and half wrapping, wherein the full wrapping has better protection for the second antenna 14, thereby preventing corrosion caused by the full contact of the second antenna 14 with the air outside the shell 15, which affects the durability of the antenna; the antenna clearance of the half wrapping is better than that of the full wrapping; the fish line 11 can also not wrap the second antenna 14 exposed to the shell 15 of the ear canal hearing aid, so that the second antenna 14 has a large clearance, thereby improving the antenna performance. At the same time, the material of the fish line 11 can be plastic or polymer material, or one or more materials, such as polyether block amide or other thermoplastic elastomers, or reinforced fibers, such as aramid fibers, which can balance elasticity and rigidity, and can realize bending and rigid protection of the antenna.

[0099] Further, as shown in Figure 12 , including the PCB mainboard 12 (integrated with the antenna mainboard 6), the fish line 11, the hearing aid shell 15, the antenna main body 18, the antenna main body 18 can extend in the direction away from the hearing aid body 10 along the inside of the fish line 11, and the length of the antenna main body 18 can be almost equal to the length of the fish line 11, or shorter than the length of the fish line 11. Among them, the outer pull line composed of the fish line 11 and the antenna main body 18 can be straight or curved, and the curvature of the outer pull line composed of the fish line 11 and the antenna main body 18 is related to the performance of the antenna, further, the total length of the fish line 11 is within 35mm.

[0100] In some embodiments of the present embodiment, when the second antenna 14 is at least partially arranged in the fish line 11 or the second antenna 14 alone exists to serve as the fish line 11, the second antenna 14 has the characteristics of being bendable into multiple radii, wherein the radius refers to the included angle between the second antenna 14 and the horizontal reference line 19, with the center line of the ear canal hearing aid body as the horizontal reference line.

[0101] Specifically, refer toFigure 13 When the curvature of the second antenna 14 used as the fish line 11 is 0, the performance of the antenna is the best, but the concealment of the second antenna in the ear canal of the user is the worst, and there is a large power consumption. Compared with the in-the-ear hearing aid in the industry which sets the antenna completely inside the hearing aid body, the antenna performance of the second antenna 14 with a curvature of 0 degrees can be improved by 20 dB. When the curvature of the second antenna 14 is between 70 degrees and 130 degrees, better antenna performance and concealment of the second antenna in the ear canal of the user can be achieved. Specifically, refer to Figure 15 When the curvature of the second antenna 14 is 70 degrees, the second antenna 14 can better fit the contour of the ear canal of the user. At the same time, compared with the in-the-ear hearing aid in the industry which sets the antenna completely inside the hearing aid body, the antenna performance of the second antenna 14 with a curvature of 70 degrees can be improved by 10 dB.

[0102] Refer to Figure 17 When the curvature of the second antenna 14 exceeds 180 degrees and reaches about 360 degrees, that is, the second antenna 14 has made a full circle, compared with the second antenna with a curvature of 0 degrees, better antenna concealment can be achieved, and compared with the second antenna with a curvature of 180 degrees, better antenna performance can be achieved.

[0103] Further, since the second antenna 14 has a flexible characteristic, the antenna performance in different scenes can be achieved by adjusting the fish line 11 to different curvatures. Among them, the smaller the curvature of the second antenna 14, the better the antenna performance, and it is more suitable for the use scene of the communication between the hearing aids on the left and right sides of the human ear or the communication connection with the device far away from the hearing aid (such as a television far away from the hearing aid), but it will cause higher power consumption and poorer antenna concealment; the larger the curvature of the second antenna 14, the weaker the antenna performance, but the power consumption is lower, the antenna concealment is better, and it is suitable for the use scene of connecting a mobile phone or using a hearing aid as a Bluetooth device, therefore, the user can adjust the second antenna 14 or the fish line 11 including the second antenna 14 to a smaller state with a relatively flat curvature when needing to communicate between the two hearing aids, and can bend the second antenna 14 or the fish line 11 including the second antenna 14 to a larger curvature when needing to connect a mobile phone, so as to balance the power consumption of the hearing aid and improve the user experience and prolong the use time of the hearing aid under the condition of meeting the antenna performance in different use scenes.

[0104] In some other embodiments of the present embodiment, the second antenna 14 can also not be arranged in the fish line 11. Specifically, the second antenna 14 is arranged outside the hearing aid shell 15, but is independent of the fish line 11, at this time, the second antenna 14 can not be wrapped with an external material or be fully wrapped or semi-wrapped with a corrosion-resistant external material, and the in-the-ear hearing aid also separately provides a fish line 11 for pulling the in-the-ear hearing aid. At this time, refer to Figure 14 ,Figure 16 and Figure 18 The second antenna 14 can be arranged above or below the fishing line 11, or the second antenna 14 and the fishing line 11 can not be arranged on the same horizontal line. The length of the fishing line 11 and the second antenna 14 is not limited, and the second antenna 14 can be shorter than, equal to, or longer than the length of the fishing line 11. The shape of the fishing line 11 and the second antenna 14 is not limited.

[0105] Preferably, when the second antenna 14 is arranged at least partially in the fishing line 11, or the second antenna 14 serves as the fishing line 11 for pulling the ear canal hearing aid, the shape of the second antenna 14 is not limited, for example, as shown in Figure 13 When the antenna body 18 is a monopole antenna or an inverted F antenna, the shape of the second antenna 14 (which can also be the fishing line 11) can be a straight line, and one end of the second antenna 14 (which can also be the fishing line 11) is fixedly connected to the ear canal hearing aid body 10, and the other end is arranged away from the ear canal hearing aid body 10 (i.e., the direction of the ear canal). As shown in Figure 19 When the antenna body 18 is a loop antenna, the shape of the second antenna 14 (which can also be the fishing line 11 including the second antenna 14) can be an arc or a polygonal shape, and the first end and the second end of the second antenna 14 (which can also be the fishing line 11 including the second antenna 14) are fixedly connected to the ear canal hearing aid body 10, and the fixed connection points of the first end and the second end are points A and B on the hearing aid shell 15, and the second antenna 14 between the points A and B has a protruding portion that can protrude outside the ear canal hearing aid body 10.

[0106] Preferably, as shown in Figure 6 The fishing line 11 is arranged on the surface of the hearing aid body 10 away from the ear canal, and the fishing line 11 can be arranged on the upper / middle / lower part of the surface away from the ear canal, close to or away from the inner wall of the concha, close to the tragus, or close to the antihelix. The specific position is not limited. The end of the fishing line 11 away from the hearing aid body 10 can be provided with a fixator 17, and the specific shape is not limited. Preferably, the cross-sectional size of the fixator 17 is larger than the cross-sectional size of the fishing line, and the fixator 17 is a spherical convexity, which is convenient for the user to hold and grasp the fishing line 11 when pulling the hearing aid, and prevents the fishing line 11 from being slippery and difficult to position, so that the hearing aid cannot be pulled out of the ear canal. Further, a sensor or the like can be arranged on the fixator 17 to realize the expansion of the function of the ear canal hearing aid.
