[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0028] As Figure 1 shown, an embodiment of the present invention provides a hearing aid, including:

[0029] A main body 10, the main body 10 includes a card slot 11 and a sound output port 12. The sound output port 12 is located at one end of the main body 10, and the card slot 11 is located on the side of the main body 10;

[0030] A receiver 20, the receiver 20 is communicated with the sound output port 12 of the main body 10 through a connecting tube 21;

[0031] An earhook 30, the earhook 30 includes an adjacent first part and a second part. A slide rail is provided on the first part of the earhook 30, and the slide rail is movably connected to the card slot 11, and the second part abuts against the connecting tube 21.

[0032] The above-mentioned main body 10 is of a hollow structure. The hollow structure inside the main body 10 forms a receiving cavity, and the receiving cavity is used to arrange components such as a control chip, a sound collection component, a sound amplification component, and a regulation component. The main body 10 is used to collect and amplify sound.

[0033] Among them, the card slot 11 of the main body 10 is used for movably connecting with the first part of the ear hook 30, and the direction of the card slot 11 is parallel to the wearing direction of the user's ear during wearing. The sound output port 12 of the main body 10 is connected to the earphone 20 and is used for outputting amplified sound.

[0034] Furthermore, the side surface of the main body 10 provided with the card slot 11 will contact the user's ear during wearing, and the shape of this side surface needs to be set as a curved shape to adapt to the shape of the user's ear.

[0035] The above-mentioned earphone 20 and the sound output port 12 of the main body 10 are communicated through a connecting pipe 21, which is used for leading the amplified sound into the user's ear.

[0036] Among them, the connecting pipe 21 is a flexible pipe, and the earphone 20 and the sound output port 12 of the main body 10 are communicated through the flexible pipe, so that it is convenient for the user to put the earphone 20 into or remove it from the ear while wearing the ear hook 30.

[0037] The above-mentioned ear hook 30 is used for hanging on the ear to enable the earphone 20 and the main body 10 to move with the user.

[0038] It should be noted that since the ear sizes of different users are different, the ear hook 30 and the main body 10 need to be movably arranged, and the relative position between the ear hook 30 and the main body 10 is adjusted to adapt to ear sizes of different sizes.

[0039] Specifically, the ear hook 30 includes an adjacent first part and a second part. The first part of the ear hook 30 is provided with a slide rail, and the slide rail is movably connected to the card slot 11. In this way, the ear hook 30 and the main body 10 are movably connected through the slide rail and the card slot 11, and the ear hook 30 can move along the direction of the card slot 11; while the second part is directly connected to the ear, so as to change the adaptable ear size.

[0040] Among them, in the case of a smaller ear size, the first part of the ear hook 30 moves downward horizontally, driving the second part of the ear hook 30 to move downward, so as to adapt to a smaller ear size; in the case of a larger ear size, the first part of the ear hook 30 moves upward horizontally, driving the second part of the ear hook 30 to move upward, so as to adapt to a larger ear size.

[0041] Among them, the second part abuts against the connecting pipe 21 to support the connecting pipe 21, so that the connecting pipe 21 can be located above the user's ear during wearing, stretching and fixing the earphone 20, so that the earphone 20 can be located in the user's ear.

[0042] In an embodiment of the present utility model, the hearing aid includes: a main body 10, the main body 10 includes a card slot 11 and a sound output port 12, the sound output port 12 is located at one end of the main body 10, and the card slot 11 is located on the side of the main body 10; a receiver 20, the receiver 20 and the sound output port 12 of the main body 10 are communicated through a connecting pipe 21; an earhook 30, the earhook 30 includes an adjacent first part and a second part, a slide rail is provided on the first part of the earhook 30, the slide rail is movably connected to the card slot 11, and the second part abuts against the connecting pipe 21. In this way, by movably connecting the first part of the earhook 30 with the card slot 11, the movement of the second part is driven, and thus the adaptation to ears of different sizes is realized, and the wearing flexibility of the hearing aid is improved.

[0043] In one embodiment, as Figure 2 shown, an elastic member 31 is provided on one side of the card slot 11 close to the second part of the earhook 30, and one end of the elastic member 31 away from the card slot 11 abuts against the first part of the earhook 30.

[0044] It should be noted that the movement between the card slot 11 and the slide rail will cause wear, resulting in weak fixing stability between the card slot 11 and the slide rail after a period of use and easy movement.

[0045] In an embodiment of the present utility model, an elastic member 31 is provided on one side of the card slot 11 close to the second part of the earhook 30, and one end of the elastic member 31 away from the card slot 11 abuts against the first part of the earhook 30. By squeezing the first part of the earhook 30 with the elastic member 31, the fixing stability between the card slot 11 and the first part is enhanced. At the same time, when the first part needs to move relative to the card slot 11, the user can pinch the elastic member 31 and move the first part of the earhook 30 at the same time, and release the elastic member 31 after the movement is completed to realize the movement of the first part relative to the card slot 11.

[0046] In one embodiment, as Figure 2 and Figure 3 shown, a plurality of first grooves 111 are arranged in parallel on the first inner surface of the card slot 11, and an elastic protrusion 32 is further provided on one side of the first part of the earhook 30 close to the first inner surface. When using the hearing aid, the protrusion is located in one of the plurality of first grooves 111.

[0047] The shapes of the above-mentioned plurality of first grooves 111 are mutually adapted, the sizes of the plurality of first grooves 111 are mutually adapted, and the elastic protrusion 32 can be installed in each of the first grooves 111. The limit is realized by the elastic protrusion 32 abutting against the side surface of the first groove 111, and the stability between the first part of the earhook 30 and the card slot 11 is improved.

[0048] Among them, the elastic protrusion 32 is fixed at the position of the first part of the earhook 30. By placing the elastic protrusion 32 in different first grooves 111, the relative position of the earhook 30 and the card slot 11 can be changed, so as to adapt to different ear sizes.

[0049] Specifically, when normal wearing does not require adjustment, the elastic protrusion 32 is placed in the first groove 111. When it is necessary to adjust the relative position of the earhook 30 and the card slot 11, the user exerts force in the moving direction of the earhook. At this time, the elastic protrusion 32 is stressed and deformed, extruded out of the first groove 111 until the next first groove 111, and the elastic protrusion 32 protrudes again to achieve position fixation, thereby changing the relative position of the earhook 30 and the card slot 11.

[0050] In the embodiment of the present utility model, a plurality of first grooves 111 are arranged in parallel on the first inner surface of the card slot 11. An elastic protrusion 32 is also provided on the side of the first part of the earhook 30 close to the first inner surface. When using the hearing aid, the protrusion is located in one of the plurality of first grooves 111. In this way, the limit is realized by the side contact between the elastic protrusion 32 and the first groove 111, and the stability of the first part of the earhook 30 and the card slot 11 is improved. At the same time, by placing the elastic protrusion 32 in different first grooves 111, the relative position of the earhook 30 and the card slot 11 can be changed, so as to adapt to different ear sizes.

[0051] In one embodiment, the shape of the elastic protrusion 32 is adapted to the shape of each of the plurality of first grooves 111, and the size of the elastic protrusion 32 is adapted to the size of each of the first grooves 111.

[0052] In the embodiment of the present utility model, the shape of the elastic protrusion 32 is adapted to the shape of each of the plurality of first grooves 111, and the size of the elastic protrusion 32 is adapted to the size of each of the first grooves 111, so that the elastic protrusion 32 can be arranged in different first grooves 111, thereby adapting to different ear sizes.

[0053] In one embodiment, as Figure 4 shown, at least one first protrusion 112 is provided on the first inner surface of the card slot 11 in the moving direction of the earhook 30; and / or,

[0054] At least one second protrusion 113 is provided on the second inner surface of the card slot 11 in the moving direction of the earhook 30, and the first inner surface and the second inner surface of the card slot 11 are opposite to each other.

[0055] The above-mentioned first protrusion 112 is arranged in the moving direction of the earhook 30, so that when the earhook 30 moves, it only acts on a single point of the cross-section of the earhook 30 without affecting the movement of the earhook 30; while when the earhook 30 is removed or replaced in a direction perpendicular to the moving direction, a surface extrusion is applied to the side of the earhook 30 close to the first inner surface, and the acting force is relatively large, thereby preventing the earhook 30 from detaching from the card slot 11 during normal use.

[0056] The above-mentioned second protrusion 113 is arranged in the moving direction of the earhook 30, so that when the earhook 30 moves, it only acts on a single point of the cross-section of the earhook 30 without affecting the movement of the earhook 30; while when the earhook 30 is removed or replaced in a direction perpendicular to the moving direction, a surface extrusion is applied to the side of the earhook 30 close to the second inner surface, and the acting force is relatively large, thereby preventing the earhook 30 from detaching from the card slot 11 during normal use.

[0057] In the embodiment of the present utility model, at least one first protrusion 112 is provided on the first inner surface of the card slot 11 in the moving direction of the earhook 30; and / or, at least one second protrusion 113 is provided on the second inner surface of the card slot 11 in the moving direction of the earhook 30, and the first inner surface and the second inner surface of the card slot 11 are opposite to each other. In this way, the acting force when the earhook 30 is removed or replaced in a direction perpendicular to the moving direction is enhanced by at least one first protrusion 112 and / or at least one second protrusion 113, preventing the earhook 30 from detaching from the card slot 11 during normal use and improving the connection stability.

[0058] In one embodiment, at least one second groove is provided on one side of the first part of the earhook 30 close to the first inner surface, the second groove corresponds to the first protrusion 112, and the first protrusion 112 is located in the second groove; and / or,

[0059] At least one third groove is provided on one side of the first part of the earhook 30 close to the second inner surface, the third groove corresponds to the second protrusion 113, and the second protrusion 113 is located in the third groove.

[0060] The above-mentioned second groove corresponds to the first protrusion 112, making the resistance smaller when the first part of the earhook 30 and the card slot 11 move. Among them, the shape of the second groove is adapted to the shape of the first protrusion 112, and the size of the second groove is adapted to the size of the first protrusion 112, so that when the first protrusion 112 is located in the second groove, the first part of the earhook 30 and the card slot 11 can move smoothly, and when the first protrusion 112 is not located in the second groove (for example, when the earhook 30 is removed or replaced), the first protrusion 112 squeezes the first part of the earhook 30, preventing the earhook 30 from detaching from the card slot 11 during normal use and improving the connection stability.

[0061] The above-mentioned third groove corresponds to the second protrusion 113, so that the resistance when the first part of the earhook 30 moves with the card slot 11 is smaller. Among them, the shape of the third groove is adapted to the shape of the second protrusion 113, and the size of the third groove is adapted to the size of the second protrusion 113, so that when the second protrusion 113 is located in the second groove, the first part of the earhook 30 and the card slot 11 can move smoothly. When the second protrusion 113 is not located in the third groove (for example, the earhook 30 is removed or replaced), the first protrusion 112 presses the first part of the earhook 30 to prevent the earhook 30 from detaching from the card slot 11 during normal use, improving the stability of the connection.

[0062] In an embodiment of the present invention, at least one second groove is provided on the side of the first part of the earhook 30 close to the first inner surface, the second groove corresponds to the first protrusion 112, and the first protrusion 112 is located in the second groove; and / or, at least one third groove is provided on the side of the first part of the earhook 30 close to the second inner surface, the third groove corresponds to the second protrusion 113, and the second protrusion 113 is located in the third groove. In this way, the resistance when the card slot 11 moves can be reduced through the second groove and / or the third groove, making the movement smoother.

[0063] In one embodiment, a fourth groove is provided on the side of the second part of the earhook 30 above the horizontal.

[0064] In an embodiment of the present invention, the fourth groove is used to place the connecting pipe 21, so that while the second part of the earhook 30 supports the connecting pipe 21, the movement position of the connecting pipe 21 is restricted through the fourth groove, preventing the connecting pipe 21 from detaching from the earhook 30 and causing the earphone 20 to leave the user's ear, improving the stability of the hearing aid during use.

[0065] In some embodiments, the size of the fourth groove is adapted to the size of the connecting pipe 21, and the shape of the fourth groove is adapted to the shape of the connecting pipe 21.

[0066] In one embodiment, the width of the fourth groove is greater than or equal to the outer diameter of the connecting pipe 21.

[0067] In an embodiment of the present invention, the width of the fourth groove is greater than or equal to the outer diameter of the connecting pipe 21, so that the connecting pipe 21 can be stably placed in the fourth groove, preventing the connecting pipe 21 from detaching from the fourth groove during wearing.

[0068] In one embodiment, the second part of the earhook 30 is an elastic structure, and the second part of the earhook 30 fits on the outer periphery of the ear during wearing.

[0069] In the embodiment of the present utility model, since the second part of the earhook 30 directly contacts the user's ear, in order to adapt to ears of different sizes, the second part of the earhook 30 is set as an elastic structure. In this way, when worn, the second part of the earhook 30 fits the outer periphery of the ear to achieve adaptation to ears of different sizes.

[0070] Among them, the second part of the earhook 30 can be pre-made into a curved shape. When the user wears it, the second part of the earhook 30 changes its shape under the action of the earphone 20 and the connecting tube 21, so that it fits the outer periphery of the ear when worn.

[0071] In one embodiment, the shape of the first part of the earhook 30 is adapted to the shape of the card slot 11, and the size of the first part of the earhook 30 is adapted to the size of the card slot 11.

[0072] In the embodiment of the present utility model, the shape of the first part of the earhook 30 is adapted to the shape of the card slot 11, and the size of the first part of the earhook 30 is adapted to the size of the card slot 11, so that the first part of the earhook 30 can be snap-fitted with the card slot 11 and can be moved according to the size of the user's ear to achieve adaptation to ears of different sizes.
