[0036] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are described clearly and completely.

[0037] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0038] In the description of the present utility model, the meaning of "several" is one or more, the meaning of "many" is two or more, "greater than", "less than", "exceed", etc. are understood to exclude the number, and "above", "below", "within", etc. are understood to include the number. It should also be understood that the term "and / or" used in the specification of this application and the attached claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes these combinations. The terms "include", "comprise", "have" and their variations all mean "including but not limited to", unless otherwise specifically emphasized.

[0039] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0040] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0041] The utility model provides a magnetic charging integrated bone conduction earphone charging assembly and a bone conduction earphone through improvement. The technical solution of the utility model is:

[0042] The present application provides a magnetic charging integrated bone conduction earphone charging assembly, see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the magnetic charging integrated bone conduction earphone charging assembly of the utility model. Figure 2 It is a structural schematic diagram of the charging stand 1 of the utility model.

[0043] The magnetic charging integrated bone conduction headset charging component can be applied not only to bone conduction headsets, but also to glasses, smart bracelets, hearing aids, smart watches, smart accessories, etc., or any combination thereof. For example, the magnetic charging integrated bone conduction headset charging component can be applied to functional myopia glasses, reading glasses, cycling glasses or sunglasses, etc., and can also be applied to intelligent glasses, such as audio glasses with headset function.

[0044] It is easy to understand that the traditional plug-and-unplug charging method requires the cable plug to be inserted into the device when charging, and the plug is easy to loosen or damage, resulting in charging failure or device damage, which is not very convenient to use. Therefore, this embodiment is provided with a magnetic charging integrated bone conduction headset charging component, see Figure 1 and Figure 2 The magnetic charging integrated bone conduction headset charging component includes a charging base 1 and a charging head 2. The charging base 1 and the charging head 2 are connected by magnetic attraction. The magnetic charging method can automatically adapt to the angle and position of the device, which is more flexible and convenient, and does not require frequent plugging and unplugging, making it more convenient to use.

[0045] Specifically, the charging stand 1 includes at least one first charging pin 11 and at least one second charging pin 12, the second charging pin 12 is made of magnetic metal material, the first charging pin 11 and the second charging pin 12 are used to electrically connect with the charging head for charging, and there is no need to set up an additional magnet block in the body shell of the bone conduction earphone. The charging method of the magnetic attraction structure that integrates the second charging pin 12 and the magnet is adopted, and the magnet does not need to occupy additional space, and the body of the bone conduction earphone becomes thinner. In addition, the area occupied by the first charging pin 11 and the second charging pin 12 is not large, which is more convenient for designing circuits and waterproof structures in the shell of the bone conduction earphone.

[0046] Correspondingly, the charging head 2 includes at least one third charging needle 21 and at least one magnetic column 22, wherein the third charging needle 21 is used to be electrically connected to the first charging needle 11, and the magnetic column 22 is used to be magnetically connected to the second charging needle 12. The outer surface of the magnetic column 22 is plated with a metal layer, and the metal layer is plated on the surface of the magnetic column 22, so that the magnetic column 22 can be connected to the second charging needle 12 to charge the bone conduction earphone. The magnetic column 22 is used to magnetically cooperate with the second charging needle 12 on the charging seat 1, and the magnetic attraction between the magnetic column 22 and the second charging needle 12 makes the first charging needle 11 and the third charging needle 21 attached to each other and connected.

[0047] This embodiment uses a second charging needle 12 made of magnetic material to replace a magnet. For example, the second charging needle 12 is made of iron metal. The iron second charging needle 12 satisfies the charging function while reducing the space occupied by the built-in magnet. There is no need to place a magnet inside the body of the bone conduction headset, so the shell 41 of the bone conduction headset does not need to increase the magnet avoidance thickness. The body is made smaller and thinner. The charging head 2 is provided with a metal-plated magnetic column 22, and the second charging needle 12 is attached to the metal-plated magnetic column 22 to attract each other. While satisfying the charging function, the charging thickness space of the charging part in the bone conduction headset is smaller.

[0048] It is easy to understand that during the charging process, problems such as overcharging, over-discharging, over-current, over-voltage, and short circuit may occur, which may damage the bone conduction headphones. Figure 2 The charging stand 1 also includes a first circuit board 13, the first charging pin 11 and the second charging pin 12 are both electrically connected to the first circuit board 13, and the first circuit board 13 is electrically connected to a battery (not shown); the charging head 2 also includes a second circuit board 23, and the third charging pin 21 and the magnetic column 22 are both electrically connected to the second circuit board 23. The first circuit board 13 and the second circuit board 23 can protect the battery in many aspects, such as preventing the battery from overcharging, overdischarging, overcurrent, overvoltage, short circuit and other problems, thereby protecting the battery from damage; and through the management and control of the first circuit board 13 and the second circuit board 23, the stable output of current and voltage can be ensured, thereby improving the charging efficiency of the bone conduction headset and shortening the charging time. The second circuit board 23 is electrically connected to a charging cable 25, and the charging cable 25 is used to connect to a power source. The charging cable 25 may include a core wire and a protective cover, and the protective cover is used to protect the core wire.

[0049] See also Figure 3 , Figure 3It is a schematic diagram of the structure of the charging head 2 of the utility model. The second circuit board 23 and the magnetic column 22 are connected through the spring clip 24. First of all, the connection of the spring clip 24 can ensure that the connection between the magnetic column 22 and the second circuit board 23 is stable and reliable, and avoid the loosening or falling of the magnetic column 22 during the charging process, thereby ensuring the safety and stability of charging. Secondly, the spring clip 24 has certain mechanical strength and toughness, and can effectively withstand the suction from the magnetic column 22 and the second charging needle 12 and the vibration during use, so as to ensure the reliability of the connection. The spring clip 24 is made of a material with good conductivity to ensure that the current can flow smoothly through the magnet, thereby achieving efficient charging.

[0050] In some embodiments, two of the first charging needle 11, the second charging needle 12, the third charging needle 21 and the magnetic column 22 are each provided, wherein the two second charging needles 12 are respectively located outside the two first charging needles 11 to form a straight line, and the two magnetic columns 22 are respectively located outside the two third charging needles 21 to form a straight line. The provision of two of the first charging needles 11, the second charging needle 12, the third charging needle 21 and the magnetic column 22 can better distribute the current and avoid the problem of damage to the bone conduction headset due to overheating of a single charging needle or excessive current. At the same time, the provision of multiple charging needles can also increase the contact area and stability during charging, and improve the safety and reliability of charging. In addition, the extra charging needles can not only be used for charging bone conduction headsets, but also for data transmission between computers, mobile phones, tablets and other devices and bone conduction headsets. Two second charging needles 12 and two magnetic strips and magnetic columns 22 are provided for more secure magnetic attraction. The second charging needles 12 are respectively located on the outsides of the two first charging needles 11 to form a straight line, and the magnetic columns 22 are respectively located on the outsides of the two third charging needles 21 to form a straight line. In this way, both sides of the first charging needle 11 and the third charging needle 21 are firmly magnetically connected. When the charging head is subjected to external force, the first charging needle 11 and the third charging needle 21 are not easily separated.

[0051] It is easy to understand that the principle of magnetic charging is to achieve circuit conduction through the magnetic attraction of magnets, thereby achieving the transmission of electrical energy. Therefore, there needs to be a certain contact pressure between the charging base and the charging head to ensure the stable transmission of current. Figure 1, the second charging needle 12 has a first height difference with the first charging needle 11, and the third charging needle 21 has a second height difference with the magnetic column 22; the second height difference is greater than the first height difference, and when the charging stand 1 and the charging head 2 cooperate to charge, the third charging needle 21 elastically contracts and presses against the first charging needle 11. If the third charging needle 21 is fixed or inelastic, as time goes by, the third charging needle 21 may be bent, deformed or worn, resulting in poor contact between the third charging needle 21 and the first charging needle 11 or unstable current transmission. By setting the third charging needle 21 as an elastically contracted charging needle, the third charging needle 21 can automatically adjust its shape and position during use, maintain good contact with the first charging needle 11, and thus ensure stable current transmission. In addition, the elastically contracted third charging needle 21 can also reduce the wear and pressure on the first charging needle 11, and improve the service life and reliability of the charging stand 1 and the charging head 2.

[0052] In some embodiments, the diameter of the magnetic column 22 is greater than the diameter of the second charging needle 12. When the magnetic column 22 and the second charging needle 12 are offset or vibrated during charging, the second charging needle 12 can always be in contact with the magnetic column 22, so as to make the connection between the magnetic column 22 and the second charging needle 12 more stable and ensure the reliability of the connection. The second charging needle 12 with a smaller diameter and the magnetic column 22 with a larger diameter are provided, while the reliability of the connection between the charging seat 1 and the charging head 2 is met, and the volume of the bone conduction earphone is reduced, so that the structure of the electronic device using the charging assembly described in this embodiment is more compact.

[0053] This embodiment also provides a bone conduction headset, see Figure 4 , Figure 4 It is a structural schematic diagram of the bone conduction earphone of the utility model.

[0054] The bone conduction earphone includes the above-mentioned charging seat 1, and also includes: a rear hanger 3, a control unit 4 and a sounding unit 5. The rear hanger 3 is used to hang on the user's neck to fix the bone conduction earphone to prevent the bone conduction earphone from falling off during use. The control unit 4 is used to realize the functions of the bone conduction earphone making sound, adjusting the volume of the bone conduction earphone sound, charging power or switching songs. The control unit 4 is fixedly connected to the end of the rear hanger 3, and the charging seat 1 is located in the control unit 4. The sounding unit 5 is used to make sound. The sounding unit 5 is connected to the control unit 4 through an ear hook 6. The ear hook 6 is used to hang on the human ear. The ear hook 6 keeps the sounding unit 5 close to the human ear to ensure that the user can hear the sound emitted by the sounding unit 5. The structure of the sounding unit 5 can adopt the conventional technical solution in the prior art, which will not be repeated in this embodiment.

[0055] In this embodiment, the back hook 3 and the ear hook 6 both include a metal strip bent into an arc, a silicone sleeve wrapped around the metal strip, and a wire (not shown) wrapped between the metal strip and the silicone sleeve. The material of the metal strip includes but is not limited to metal element, alloy or metal matrix composite material, etc. Preferably, the metal strip is made of memory alloy, and the memory alloy is used in conjunction with the silicone sleeve, which can not only improve the elasticity of the entire earphone back hook 3 and ear hook 6 and maintain a constant clamping force of the back hook 3; and the silicone sleeve is soft and elastic, and has high affinity with the skin, thereby effectively ensuring the fit between the back hook 3 and the ear hook 6 and the human body and the wearing comfort.

[0056] In some embodiments, see Figure 4 , Figure 5 and Figure 6 . The control unit 4 includes a shell 41, and the first circuit board 13 is located in the shell 41. The shell 41 is used to accommodate the electronic devices in the bone conduction headset. A charging slot 411 is provided on the shell 41, and the first charging pin 11 and the second charging pin 12 are located in the charging slot 411. The charging slot 411 is used to fix the first charging pin 11 and the second charging pin 12. A limiting groove 412 is provided on the shell 41, and the charging slot 411 is located in the limiting groove 412. The limiting groove 412 is used to limit the charging head 2 during charging. If the position between the charging seat and the charging head is not accurate, it may cause problems such as poor charging effect, poor contact or even damage of the bone conduction headset. The setting of the limiting groove 412 can limit the position of the charging head 2, ensure that the charging head 2 and the charging seat 1 are accurately aligned, thereby ensuring stable transmission of current.

[0057] In some embodiments, see Figure 5 and Figure 7 , Figure 5 It is a schematic diagram of the structure explosion of the control unit 4 of the utility model. Figure 7 It is a partial structural diagram of the control unit 4 of the utility model.

[0058] A waterproof cover 42 is provided between the first circuit board 13 and the housing 41. The waterproof cover 42 is used for waterproofing. When the earphone is in a humid environment or encounters water, the waterproof cover 42 can effectively prevent moisture from entering the control unit 4, thereby protecting the circuits and components of the earphone from damage. A glue groove 421 is left between the waterproof cover 42 and the housing 41. The glue groove 421 is used to fill glue. On the one hand, the glue can fix the waterproof cover 42; on the other hand, by applying glue in the glue groove 421, the first circuit board 13 can be completely isolated from the outside world under the protection of the waterproof cover 42 and the housing 41, protecting the electronic components and circuits inside the bone conduction earphone from the influence of the external environment, thereby extending the service life of the earphone.

[0059] In some embodiments, see Figure 5 The housing 41 includes an inner housing 413 and an outer housing 414. The inner housing 413 is made of a hard material, and the outer housing 414 is made of a silicone material. The inner housing 413 and the outer housing 414 are used together. The inner housing 413 is used for support, and the outer housing 414 can improve the elasticity of the entire control unit 4.

The front inner housing 4131 and the rear inner housing 4132, the front outer housing 4141 and the rear outer housing 4142 can be manufactured and processed separately, and then connected together through a simple assembly operation. Moreover, the internal parts can be easily repaired and replaced.
