[0073] Combine the following Figures 1 to 11 , describing an embodiment of the utility model.

[0074] According to an embodiment of the present utility model, on the one hand, an ear-worn hearing aid device is provided, comprising:

[0075] Equipment body 1;

[0076] The fixing structure is arranged on the device body 1 , and the fixing structure is formed into a ring structure with an opening 511 , which is suitable for auxiliary fixing the device body 1 to the auricle 7 of the wearer.

[0077] The fixed structure on the device body 1 forms a ring structure with an opening 511. The device body 1 is auxiliary fixed to the wearer's auricle 7 by utilizing the adaptation and limiting of the fixed structure and the auricle 7 structure, thereby improving the fixing reliability of the device body 1. The device body 1 is not easy to loosen, the wearer does not need to touch and adjust it frequently, and there will be no whistling caused by hand touch, thereby improving the user experience.

[0078] In one embodiment, the fixing structure comprises:

[0079] The ear button 5 is rotatably arranged on the device body 1;

[0080] The ear buckle 5 has an open position for opening by rotating along its rotation axis and a closed position for closing by rotating along its rotation axis. In the closed position, the ear buckle 5 can at least close to the auricle 7 of the wearer and be limited by the helix 8.

[0081] The ear buckle 5 of the fixed structure can be rotatably arranged on the device body 1. When the user wears the hearing aid or earphone, the ear buckle 5 is rotated to the buckling position, buckled at the wearer's helix 8 and limited by the bending structure of the helix 8, thereby improving the connection reliability between the device and the ear. The fixing reliability is high, and even a simplified ear-worn device is not easy to loosen. The wearer does not need to touch and adjust frequently, so there will be no whistling caused by hand touch, which improves the user's experience. The fixed structure is simple in structure and easy to wear, and the ear buckle 5 has a significant fixing effect on the device body 1.

[0082] Furthermore, the ear buckle 5 can also be configured to be a structure larger than a semicircular ring, that is, the end of the ear buckle 5 is bent back, and the bent structure of the ear buckle 5 can be used to improve the tightness of the fit between the ear buckle 5 and the helix 8 to prevent it from flipping back and leaving the fastening position.

[0083] It should be noted that, in some other embodiments, the ear clip 5 can also be fixedly mounted on the device body 1, and the ring structure of the ear clip 5 and the structure of the auricle 7 are used to achieve embedded positioning.

[0084] In one embodiment, as 2 and Figure 3 As shown, the ear stud 5 comprises:

[0085] Buckle body 51;

[0086] The pivoting portion 52 is disposed at the first end of the buckle body 51 and is rotatably connected to the device body 1;

[0087] The engaging portion 53 is disposed at the second end of the buckle body 51 away from the pivoting portion 52 and is used for being engaged with the wearer's ear helix 8 .

[0088] The pivoting portion 52 at the first end of the buckle body 51 is rotatably connected to the device body 1, so as to facilitate the opening and closing of the ear buckle 5; when in the closed position, the engaging portion 53 at the second end of the buckle body 51 is engaged with the inner side of the wearer's helix 8, and the engaging portion 53 is clamped at the natural bending part of the helix 8 and is limited in position, thereby completing the limitation of the behind-the-ear hearing aid device body 1 hidden behind the ear.

[0089] In one embodiment, Figure 2 As shown, the buckle body 51 is in a semicircular ring shape.

[0090] The buckle body 51 adopts a semicircular ring structure, which fits more closely with the auricle 7, and can also make the engaging portion 53 hook back into the helix 8 when in the buckled position, further improving the fixing reliability. In addition, compared with other ring structures, the arc-shaped structure has no edges and corners, and will not scratch the ear to cause damage.

[0091] In some embodiments, Figure 3 As shown, the buckle body 51 may also adopt a ring structure composed of multiple line segments, which has certain modeling functions and is more personalized.

[0092] In some embodiments, a decorative layer may also be provided on the ear studs 5 to improve the aesthetic appearance.

[0093] In one embodiment, the engaging portion 53 includes a contact fixedly disposed on the second end of the buckle body 51 .

[0094] When buckled, the contact is wrapped in the helix 8 and fixed in position. When no external force is applied, the connection between the ear buckle 5 and the wearer's auricle 7 is very reliable, preventing the behind-the-ear hearing aid from loosening.

[0095] In one embodiment, Figure 2 As shown, the contact is a cylindrical structure.

[0096] The helix 8 of the human body is formed by bending forward at the auricle 7, and the cross-section of the semi-enclosed cavity formed on the inner side of the helix 8 is close to a circle. Therefore, the contact is set to be cylindrical to match the shape of the cavity, which improves the fixing reliability while also improving the comfort of the wearer.

[0097] It should be noted that the arrangement direction of the contacts is perpendicular to the extension direction of the buckle body 51 , so as to ensure that the direction of the contacts matches the extension direction of the cavity of the helix 8 after the buckle body 51 is flipped and buckled.

[0098] In order to further improve wearing comfort, both ends of the contact are set to be semi-spherical, or to be smooth transition surfaces, so as to reduce scratches caused by angular shapes.

[0099] According to an embodiment of the present utility model, on the other hand, a behind-the-ear hearing aid is provided, comprising:

[0100] Equipment body 1;

[0101] An ear hook 2 is arranged on the top of the device body 1 through a connecting joint and is used to hang the hearing aid on the ear of the wearer;

[0102] The sound guide tube 3 is detachably arranged at one end of the ear hook 2 away from the device body 1;

[0103] The earplug 4 is arranged at one end of the sound guide tube 3 away from the ear hook 2 and is used to be inserted into the external auditory canal;

[0104] Fixed structure, the ear buckle 5 of the fixed structure can be rotatably arranged on the device body 1.

[0105] Since the behind-the-ear hearing aid includes the fixing structure of the present invention, it has the same technical effect as the fixing structure, which will not be described in detail here.

[0106] Figure 8 and Fig. 9 The diagram shows the connection status of the BTE hearing aid and the wearer's ear when the ear hook 5 is in the open position and the buckled position. When wearing, first hang the ear hook 2 on the ear, so that the device body 1 is located behind the ear, the sound guide tube 3 and the earplug 4 are located in front of the ear, and then insert the earplug 4 into the external auditory canal, and then turn the ear hook 5 over and buckle it to the auricle 7, so that the clamping part 53 buckles into the helix 8, thereby completing the reliable fixation and wearing of the BTE hearing aid. When taking it off, flip the ear hook 5 in the opposite direction, unfasten it, pull out the earplug 4, and then take off the hearing aid hanging on the ear.

[0107] In one embodiment, a mounting portion is provided on the device body 1, and the ear buckle 5 is pivotally connected to the mounting portion.

[0108] A mounting portion is provided on the device body 1 to facilitate pivoting the ear buckle 5 to the mounting portion, thereby completing the connection between the ear buckle 5 and the device body 1 .

[0109] Specifically, the mounting portion can be integrally formed with the ear shell of the device body 1, or can be separately processed and then fixedly connected by bonding. The manufacturer can make a choice based on the process and cost requirements.

[0110] It should be noted that the mounting portion can be arranged on the left or right side of the device body 1, and is suitable for wearing on the right ear and the left ear respectively. The user can choose to purchase according to personal wearing habits. Of course, the mounting portion can also be arranged on both the left and right sides of the device body 1, and the ear buckle 5 can be detachably installed, and the wearer can choose to wear it on the right ear or the left ear as needed, which is highly flexible.

[0111] In one embodiment, Figure 4 As shown, the mounting portion includes a first protrusion 13 and a second protrusion 14 that are arranged opposite to each other. A hinge hole is provided on the first protrusion 13 and the second protrusion 14. A hinge shaft 6 is provided on the ear buckle 5. The ear buckle 5 can be rotatably arranged in the hinge hole through the hinge shaft 6.

[0112] The hinge shaft 6 is passed through the hinge holes on the first protrusion 13 and the second protrusion 14, so that the ear buckle 5 is hinged on the device body 1. The structure is simple and the opening and closing actions of the ear buckle 5 are convenient.

[0113] Specifically, the first protrusion 13 and the second protrusion 14 may be a sheet-like structure integrally formed on the surface of the ear-hanging shell of the device body 1 .

[0114] In one embodiment, the fixing structure further includes a stop structure, which is suitable for locking the ear buckle 5 in a buckled position.

[0115] By setting a stop structure, the ear buckle 5 can be conveniently locked in the buckled position. On the basis of limiting the position between the structure of the auricle 7 itself and the fixed structure, the connection reliability of the fixed structure in the buckled state can be further improved to prevent the fixed structure from detaching from the auricle 7.

[0116] In some embodiments, a protrusion is provided on the ear buckle 5 near its rotation axis to form a stop structure.

[0117] A protrusion is provided on the ear buckle 5 near its rotating shaft. When the ear buckle 5 rotates to a certain angle, the protrusion can generate a limit between the rotating shaft and / or the device body, preventing the ear buckle 5 from rotating toward the open position without the application of external force, thereby playing a locking role, further improving the stability of the ear buckle 5 in the buckled position, and ensuring that the fixing structure reliably assists in fixing the device body.

[0118] In some embodiments, the ear clip 5 is made of elastic material, and the size of the opening 511 is close to the wall thickness of the helix 8 .

[0119] The ear clip 5 is made of elastic material, and the change in the size of the opening 511 can be achieved directly through the deformation of the ear clip 5, without adding other mechanisms or components for adjusting the size of the opening 511. The structure is simple and the reliability is high. Moreover, compared with hard materials, the ear clip 5 made of elastic material also improves the wearing comfort and will not cause friction damage. Fig.10 and Fig.11 The diagrams are respectively given in the natural state and the state where the opening 511 is opened by applying force. In this embodiment, the connection portion between the ear button 5 and the device body 1 can be arranged in the middle section of the annular structure, and the ear button 5 can be fixedly connected to the device body 1, and the engagement or disengagement with the auricle 7 can be achieved only by the elastic deformation of the ear button 5.

[0120] In other embodiments, the mounting portion may be separately configured to be made of a material having elastic deformation capability, and the ear buckle 5 can directly realize a rotation movement within a certain range through the mounting portion, and a locking switch (stop structure) is added to lock the position of the ear buckle 5 through the locking switch after buckling.

[0121] In one embodiment, the ear clip 5 is disposed at the middle or upper portion of the device body 1 .

[0122] The ear buckle 5 is arranged in the middle or upper part of the device body 1. On the one hand, it can effectively limit the device body 1 to prevent the device body 1 from moving; on the other hand, after being worn, the position of the ear buckle 5 corresponds to the helix 8, which is convenient and reliable for limiting.

[0123] In some embodiments, the ear-worn hearing assistive device is a behind-the-ear hearing aid.

[0124] The behind-the-ear hearing aid adopts a fixed structure to improve the fixation reliability of the hearing aid. The behind-the-ear hearing aid is not easy to loosen, and the wearer does not need to touch and adjust it frequently. There will be no howling after the sound is amplified by hand touch, which improves the user experience.

[0125] Specifically, the device body 1 of the behind-the-ear hearing aid includes an ear-hanging shell, and a receiving cavity is formed inside the ear-hanging shell. The digital processor and receiver of the behind-the-ear hearing aid are arranged in the receiving cavity. The ear-hanging shell is provided with a button 11 and a sound receiving hole 12. The button 11 is arranged on the front of the ear-hanging shell, and the two sound receiving holes 12 are respectively arranged on the upper and lower sides of the button 11. The back of the ear-hanging shell is provided with a battery compartment 15. The ear buckle 5 is arranged on the side of the ear-hanging shell for easy operation and fixation.

[0126] like Figure 4 and Figure 6 As shown, the ear-hanging shell of the hearing aid is provided with a volume control button, a battery compartment 15 and an installation part of the ear buckle 5, and a hinge hole is provided at the center position of the first protrusion 13 and the second protrusion 14 of the installation part, and a hinge shaft 6 is installed through the hinge hole. The ear buckle 5 can be flipped along the hinge shaft 6 and rotate with the hinge shaft 6.

[0127] The user can operate the ear buckle 5 to flip with one hand, and when the hearing aid needs to be taken off, the ear buckle 5 can be easily taken off. When wearing the hearing aid, the ear hook 2 is first hung on the ear, the position of the earplug 4 is adjusted, and then the ear buckle 5 is buckled on the auricle 7 to achieve a fixing effect. The contact part between the ear buckle 5 and the helix 8 is a contact, which can be made of soft materials such as silicone or rubber to ensure the comfort of the user for a long time.

[0128] The sound guide tube 3 is detachably connected to the ear hook shell, and is used to transmit the sound collected and processed inside the ear hook shell to the eardrum of the user. The ear hook 2 used to fix the hearing aid on the ear of the user is also made of soft material.

[0129] The user presses and holds the volume control button "+" for 2s to turn on the device, and presses and holds the volume control button "-" for 2s to turn off the device. Through the improvement of the fixing structure, the hearing aid can be better fixed on the user's ear. On the other hand, due to the better fixing effect, the earplug 4 is not easily displaced in the user's external auditory canal, and can be stabilized in the most suitable position for the user's ear, preventing the sound transmitted by the sound guide tube 3 from leaking out due to poor sealing. At the same time, the user does not need to adjust it by hand due to looseness, which reduces the frequency of howling. The user experience is better than that of related products. At the same time, after setting up the fixing structure, the user does not need to customize the ear mold additionally, thereby reducing expenses.

[0130] The utility model discloses a new behind-the-ear hearing aid, which, through the fixed structure (reversible ear buckle 5 structure) provided on the device body 1, enables the user to wear the hearing aid more securely during use. The fixed structure solves the problem that the behind-the-ear hearing aid is easy to fall off. After the fixed structure is provided, the earplug 4 can be stabilized in an optimal position in the ear canal, and the earplug 4 has a good seal with the external auditory canal. The user no longer needs to intermittently adjust the hearing aid by hand, thereby avoiding whistling. Moreover, the user does not need to customize the ear mold in order to be able to wear it more securely, which reduces the cost of use and improves the user experience.

[0131] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
