[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In one embodiment of the present invention, a hearing aid, a charging box and a hearing aid system are provided. The hearing aid is provided with a wireless charging module to realize wireless charging. The wireless charging module is a winding coil, which can increase the number of windings in a limited space. Figures 1 to 6 The following further describes the hearing aid, charging case and hearing aid system in this embodiment.

[0030] Specifically, if Figures 1 to 3 As shown, the hearing aid 100 in this embodiment includes: a housing 110 , a battery 120 and a wireless charging module 130 .

[0031] The battery 120 and the wireless charging module 130 are both disposed in the housing 110 . The wireless charging module 130 includes a winding bracket 131 and a coil 132 . The coil 132 is wound around the outer periphery of the winding bracket 131 . The coil 132 is electrically connected to the battery 120 .

[0032] For example, the hearing aid 100 in this embodiment can be worn to the ear of a human body, and in particular, can be worn to the back of the ear of a human body. The hearing aid 100 is provided with a connection jack, and the connection jack can be connected to an earphone cable with an earphone. In actual use, the user can connect the earphone cable with the earphone to the hearing aid 100, then wear the hearing aid 100 to the back of the ear, and then put the earphone into the ear, so as to wear the hearing aid.

[0033] In this embodiment, the shell 110 can be made of materials such as plastic. The external shape of the shell 110 can be adapted to the human ear to facilitate effective wearing. The shell 110 has an installation cavity inside, and the relevant functional elements for hearing aid are arranged in the installation cavity.

[0034] Furthermore, a battery 120 and a wireless charging module 130 are disposed inside the housing 110 , wherein the battery 120 can supply power for normal use of the hearing aid, and the wireless charging module 130 can be used to realize wireless charging of the hearing aid 100 .

[0035] like Figure 3As shown, the wireless charging module 130 includes a winding bracket 131 and a coil 132, wherein the winding bracket 131 can be made of plastic or metal material, the winding bracket 131 has a certain length, and the coil 132 can be wound along the circumferential direction of the winding bracket 131 and arranged on the outer periphery of the winding bracket 131, and the two external terminal ends of the coil 132 can be electrically connected to the battery 120.

[0036] In actual use, when the hearing aid 100 is placed in a specific charging position, the coil 132 in the wireless charging module 130 can use the principle of electromagnetic induction to receive the electrical energy transmitted by the external coil and store the electrical energy in the battery 120, thereby charging the hearing aid 100.

[0037] In this embodiment, wireless charging can be achieved by providing a wireless charging module. Compared with the prior art in which an exposed charging pin and a precision connector are provided on the hearing aid, the poor contact problem caused by the charging pin and the precision connector can be avoided. In addition, compared with the prior art in which a flat runway-shaped coil is provided on the hearing aid 100, the winding coil 132 provided in this embodiment can be more centrally provided inside the housing 110, which can save space and leave more space for the installation of other functional components. Moreover, the coil 132 can be densely wound on the winding bracket 131, so that more turns of the coil can be arranged in a limited space, thereby ensuring the charging efficiency.

[0038] In one embodiment, Figure 2 and Figure 3 As shown, the hearing aid 100 also includes a main control board 141, which is disposed in the shell 110, the main control board 141 is located at the head of the hearing aid 100, the battery 120 is located in the middle of the hearing aid 100, and the wireless charging module 130 is located at the tail of the hearing aid 100, and the battery 120 and the wireless charging module 130 are both electrically connected to the main control board 141.

[0039] It can be understood that the main control board 141, the battery 120 and the wireless charging module 130 are sequentially arranged in three sections inside the housing 110. The main control board 141 and the wireless charging module 130 are lighter than the battery 120. By arranging the battery 120 in the middle of the entire hearing aid 100, the center of gravity of the hearing aid 100 can be located in the middle, so that when the hearing aid 100 is worn behind the ear of a person, it can be prevented from becoming loose and falling.

[0040] Moreover, a connection jack for connecting the headphone cable can be set on the head of the hearing aid 100, and the connection jack can be directly connected to the main control board 141 via a wire. At this time, the wire can be directly connected to the main control board 141 at a shorter distance, which can avoid the wire being set too long inside the shell 110, facilitating the installation of other functional components.

[0041] In one embodiment, Figure 2 and Figure 3 As shown, the main control board 141 is connected to a circuit board 142 . The circuit board 142 is located on the side of the battery 120 and extends toward the rear of the hearing aid 100 . The coil 132 is electrically connected to the circuit board 142 .

[0042] It can be understood that the main control board 141 can be a PCB board, which has a certain structural strength and needs to occupy a certain space. It can be set at the head of the hearing aid 100, and the functional elements for circuit control can be set on the PCB board. The circuit board 142 is a flexible circuit board, also known as a "soft board" or "FPC board", which is a printed circuit made of a flexible insulating substrate. One end of the circuit board 142 can be electrically connected to the main control board 141, and the other end extends from the side of the battery 120 to the tail of the hearing aid 100, and the coil 132 is electrically connected to the circuit board 142.

[0043] In actual installation, Figure 3 As shown, two contact solder joints 143 are provided at one end of the circuit board 142 close to the rear of the battery 120 , and two connection terminals led out from the coil 132 can be connected to the two contact solder joints 143 respectively.

[0044] In the above configuration, the two terminals extending from the coil 132 can be connected to the main control board at a shorter distance, which can also prevent the wires from being too long inside the housing 110 and facilitate the installation of other functional components.

[0045] In one embodiment, in order to effectively fix each functional element inside the housing 110, as shown in FIG. Figure 1 and Figure 2 As shown, the hearing aid 100 further includes a built-in bracket 150 , which is fixedly disposed in the housing 110 , and the wire winding bracket 131 , the main control board 141 and the battery 120 are fixedly disposed on the built-in bracket 150 .

[0046] For example, the built-in bracket 150 may be a structural member independent of the housing 110 , and the built-in bracket 150 is made of a light material such as plastic. The built-in bracket 150 is provided with a plurality of installation positions.

[0047] During installation, the main control board 141 and the battery 120 can be installed one by one on the mounting position of the built-in bracket 150 by means of glue, screws or snaps. Moreover, the winding bracket 131 in the wireless charging module 130 can also be fixed on the built-in bracket 150. Afterwards, the built-in bracket 150 is fixedly placed in the mounting cavity of the shell 110. Accordingly, in order to fix the built-in bracket 150 in the shell 110, as an implementation method, a plurality of snap-in positions are provided in the mounting cavity of the shell 110, and the built-in bracket 150 can be engaged to the plurality of snap-in positions, thereby, the built-in bracket 150 can be effectively fixed to the mounting cavity of the shell 110.

[0048] Alternatively, the built-in bracket 150 can also be integrally formed with the housing 110, and the built-in bracket 150 can be directly fixed in the installation cavity of the housing 110. During installation, the main control board 141 and the battery 120 can be installed on the built-in bracket 150 one by one with the help of glue, screws or buckles. Similarly, the winding bracket 131 in the wireless charging module 130 can also be fixed on the built-in bracket 150. In this way, the main control board 141, the battery 120 and the wireless charging module 130 can also be effectively fixed to the installation cavity of the housing 110.

[0049] In one embodiment, Figure 1 As shown, the housing 110 includes: an earphone surface shell 111 and an earphone bottom shell 112. The earphone surface shell 111 and the earphone bottom shell 112 are coupled to each other to form an installation cavity. The battery 120 and the wireless charging module 130 are arranged in the installation cavity. The earphone bottom shell 112 has an ear hook portion.

[0050] Exemplarily, in order to fit the back of the human ear, the shell 110 can be roughly constructed as a C-shaped structure with a certain curvature, the earphone surface shell 111 is located on the outside of the C-shaped structure, and the earphone bottom shell 112 is located on the inside of the C-shaped structure. The earphone surface shell 111 and the earphone bottom shell 112 can be tightly joined. At this time, a sealed installation cavity can be formed between the earphone surface shell 111 and the earphone bottom shell 112, and the battery 120, the wireless charging module 130, and the main control board 141 are all arranged in the installation cavity.

[0051] Furthermore, since the housing 110 is roughly constructed as a C-shaped structure, one end of the C-shaped structure is the head of the hearing aid 100, and the other end is the tail of the hearing aid 100. The main control board 141 and the wireless charging module 130 are respectively arranged at the two ends of the C-shaped structure, and the battery 120 is arranged in the middle of the C-shaped structure. In addition, the wiring jack for connecting the headphone cable can be arranged at one end of the headphone housing 111 close to the head of the hearing aid 100.

[0052] In this embodiment, the ear hook portion of the earphone bottom shell 112 can be a fitting surface of the earphone bottom shell 112 that fits to the back of the human ear, and the fitting surface is adapted to the shape of the back of the human ear. When the hearing aid is adapted and placed behind the human ear, the ear hook portion of the earphone bottom shell 112 can be adapted to fit to the back of the human ear, thereby fixing the hearing aid.

[0053] Alternatively, the ear hook portion of the earphone bottom shell 112 is a hook arranged on the earphone bottom shell 112 near the head of the hearing aid. When the hearing aid 100 is adapted and placed behind the human ear, the ear hook portion can be hooked to the human ear, thereby also fixing the hearing aid.

[0054] In actual scenarios, when the hearing aid 100 needs to be used, it is usually worn on the ear of the human body. When not in use, the hearing aid 100 can be placed in a specific charging box. The charging box can be used to accurately store the hearing aid 100 to avoid loss, and can also be used to charge the hearing aid 100. Moreover, after the hearing aid 100 is placed in the charging box, in order to prevent the hearing aid 100 from falling off the charging box, the hearing aid 100 can be fixed in the charging box by the adsorption force between the magnetic parts.

[0055] Thus, in one embodiment, Figure 1 and Figure 2 As shown, the hearing aid 100 also includes a magnetic component, which is disposed in the housing 110 and is used to engage with the charging box.

[0056] Therefore, after the hearing aid 100 is placed in a charging box having another magnetic component, the hearing aid 100 can be effectively placed in the charging box by utilizing the magnetic adsorption force between the two magnetic components.

[0057] In order to ensure that the hearing aid 100 can be accurately placed in the corresponding position of the charging box, two sets of magnets can be set inside the hearing aid 100 and inside the charging box, and two sets of magnetic adsorption forces are used to ensure that the hearing aid 100 is installed in place. For example, in one embodiment, Figure 1 and Figure 2 As shown, the magnetic member may include a first magnetic member 161 and a second magnetic member 162 , wherein the first magnetic member 161 is located at the rear portion of the hearing aid 100 , and the second magnetic member 162 is located at the middle portion of the hearing aid 100 .

[0058] It can be understood that the hearing aid 100 in this embodiment is provided with two magnetic parts, and the two magnetic parts are respectively arranged in the middle and tail of the hearing aid 100. Therefore, when the hearing aid 100 is stored in the charging box, the hearing aid 100 can be placed in the charging box in a flat manner, thereby increasing the contact area between the hearing aid 100 and the charging box, ensuring wireless charging and magnet space, and at the same time, the hearing aid 100 can be fixed with the help of the two magnetic parts.

[0059] In this embodiment, a charging box is also provided. The hearing aid in this embodiment can be placed in the charging box and can be wirelessly charged in the charging box.

[0060] Specifically, if Figure 4 and Figure 5 As shown, the charging box 200 is provided with a storage compartment capable of accommodating the hearing aid 100 , and a wireless transmission module 210 is provided inside the charging box 200 , and the wireless transmission module 210 is used to cooperate with the wireless charging module 130 to charge the battery 120 .

[0061] Exemplarily, the charging box 200 can be a box-shaped structure made of plastic or other materials, which includes a box seat and a box cover. The box cover is rotatably connected to the box seat, and an inner lining groove is provided on the side of the box seat facing the box cover. The shape of the inner lining groove is compatible with the shape of the hearing aid 100. The inner lining groove is the accommodating compartment, and the hearing aid 100 can be adapted to be placed in the accommodating compartment. Moreover, a wireless transmission module 210 is provided inside the box body. After the hearing aid 100 is placed in the accommodating compartment, the wireless charging module 130 in the hearing aid 100 can cooperate with the wireless transmission module 210 inside the box body to charge the battery 120 in the hearing aid 100.

[0062] Further, as described above, the hearing aid 100 in this embodiment is provided with a first magnetic member 161 and a second magnetic member 162, so as to effectively fix the hearing aid 100 in the receiving compartment of the charging box 200. Figure 5 As shown, a third magnetic part 231 and a fourth magnetic part 232 are provided in the box body of the charging box 200. The third magnetic part 231 is used to cooperate with the first magnetic part 161, and the fourth magnetic part 232 is used to cooperate with the second magnetic part 162. For example, the third magnetic part 231 is close to the tail of the accommodating bin, and the fourth magnetic part 232 is close to the middle of the accommodating bin.

[0063] Thus, when the hearing aid 100 is placed in the storage compartment of the charging box 200, the head of the hearing aid 100 can be placed in the head of the storage compartment, and the tail of the hearing aid 100 can be placed in the tail of the storage compartment. At this time, the positions of the third magnetic member 231 and the first magnetic member 161 correspond to each other, and the third magnetic member 231 can apply a magnetic adsorption force to the first magnetic member 161. For example, the end faces of the third magnetic member 231 and the first magnetic member 161 that are close to each other are different magnetic poles. The positions of the fourth magnetic member 232 and the second magnetic member 162 correspond to each other, and the fourth magnetic member 232 can apply a magnetic adsorption force to the second magnetic member 162. For example, the end faces of the fourth magnetic member 232 and the second magnetic member 162 that are close to each other are different magnetic poles.

[0064] Through the above-mentioned setting method, with the help of the magnetic adsorption force between the two groups of magnetic parts, the adsorption effect of the hearing aid in the storage compartment can be improved, so that the hearing aid 100 can be more tightly fixed in the charging box 200, which can ensure wireless charging and magnet space and ensure the charging effect.

[0065] Furthermore, one of the hearing aid 100 and the charging box 200 is provided with an induction magnet, and the other is provided with a Hall chip. Moreover, when the hearing aid 100 is placed in the receiving compartment, the induction magnet corresponds to the Hall chip.

[0066] In one embodiment, Figure 1 and Figure 2 As shown, an induction magnet 171 is provided in the shell 110 of the hearing aid 100, and a Hall chip 220 is provided in the charging box 200. When the hearing aid 100 is placed in the storage compartment of the charging box 200, the induction magnet 171 can trigger the Hall chip 220. At this time, the charging box 200 can sense that the hearing aid 100 is placed in place, thereby starting to charge the hearing aid 100.

[0067] Specifically, a controller and a battery element may also be provided inside the box body, and the wireless transmission module 210, the battery element and the Hall chip 220 are all electrically connected to the controller. When the Hall chip 220 is not triggered by the induction magnet 171, it indicates that the hearing aid 100 is not placed in the storage compartment of the charging box 200, and the controller may make the wireless transmission module 210 in a disconnected state according to the state of the Hall chip 220; when the Hall chip 220 is triggered by the induction magnet 171, it indicates that the hearing aid 100 has been accurately placed in the storage compartment of the charging box 200, and at this time, the controller may make the wireless transmission module 210 in a running state according to the state of the Hall chip 220, so that the electric energy in the battery element is transmitted to the battery 120 of the hearing aid 100 through the cooperation between the wireless transmission module 210 and the wireless charging module 130, thereby realizing the charging of the hearing aid 100.

[0068] Moreover, when the hearing aid 100 is taken out of the storage compartment of the charging box 200 , the induction magnet 171 on the hearing aid 100 will no longer trigger the Hall chip 220 of the charging box 200 .

[0069] Of course, in other embodiments, the induction magnet can be set in the charging box, and the Hall chip can be set in the housing of the hearing aid.

[0070] In one embodiment, the number of the accommodating chambers is two, and the two accommodating chambers are symmetrically arranged in the charging box 200, and the two accommodating chambers can respectively accommodate the hearing aids 100.

[0071] It can be understood that hearing aids 100 are usually used in pairs corresponding to the ears of the human body. Therefore, by providing two receiving compartments in the charging box 200, two hearing aids 100 can be placed in the same charging box 200 at the same time.

[0072] Furthermore, the charging box 200 is provided with a power display element, and the power display element is located between the two containing compartments.

[0073] For example, Figure 4 and Figure 5 As shown, the power display element can be a digital screen 240, which is disposed between the two receiving compartments, and is electrically connected to the controller, and the digital screen 240 can display the power of the hearing aids 100 in the receiving compartments. For example, the digital screen 240 can display the power of the hearing aids 100 in the two receiving compartments respectively.

[0074] In actual use, when the Hall chip 220 in the charging box 200 is not triggered, it means that there is no hearing aid 100 in the storage compartment of the charging box 200, and the controller does not need to supply power to the digital screen 240, and the digital screen 240 is in a power-off state. When the Hall chip 220 in the charging box 200 is triggered, it means that there is a hearing aid 100 in the storage compartment of the charging box 200, and the controller can obtain the power of the battery 120 in the hearing aid 100 according to the charging status between the wireless transmission module 210 and the wireless charging module 130, and display the corresponding power value on the digital screen 240.

[0075] In addition, the digital screen 240 can also display the power level of the battery components in the charging box 200.

[0076] In yet another embodiment, the power display element may be a display light, which is electrically connected to the controller and can display two different colors of light after being powered on according to a control signal of the controller. Moreover, there may be two display lights, which may correspond to two receiving compartments respectively.

[0077] In actual use, when the Hall chip 220 in the charging box 200 is not triggered, it means that there is no hearing aid 100 placed in the storage compartment of the charging box 200, and the controller does not need to supply power to the display light. At this time, the display light is in a power-off state.

[0078] When the Hall chip 220 in the charging box 200 is triggered, it means that a hearing aid 100 is placed in the storage compartment of the charging box 200. The controller can obtain the power of the battery 120 in the hearing aid 100 according to the charging status between the wireless transmission module 210 and the wireless charging module 130. When the controller determines that the battery 120 in the hearing aid 100 is not fully charged, the display light can be controlled to display a first color of light. When the controller determines that the battery 120 in the hearing aid 100 is fully charged, the display light can be controlled to display a second color of light.

[0079] In another embodiment, the power display element may be a digital screen and a display light, and the digital screen and the display light are used to display the power of the hearing aid in the manner described in the above embodiment.

[0080] In addition, in actual applications, in order to charge the charging box 200, a charging connector may be provided on the charging box 200, and the charging connector is electrically connected to the controller. When the charging box 200 needs to be charged, an external power cord may be connected to the charging connector, thereby transmitting external electrical energy to the battery element in the charging box 200.

[0081] In addition, in this embodiment, a hearing aid system is also provided, which includes the charging box 200 and the hearing aid 100 in this embodiment.

[0082] In one embodiment, Figure 6 As shown, the hearing aid system in this embodiment can work in the following manner:

[0083] First, the hearing aid 100 can be put into the storage compartment of the charging box 200; then, determine whether the Hall chip 220 in the charging box 200 is triggered. If the Hall chip 220 can be triggered, it means that the hearing aid 100 is in place.
