For example, the earphone end or collar of the neck-hanging bone conduction headphones is placed in the charging stand. The traditional charging stand structure is mostly provided with a groove on the top surface of the charging stand, and the bone conduction headphones or collars are placed in the corresponding grooves for charging. However, this structure has the problem of unstable and loose connection between the charging stand and the neck-hanging bone conduction headphones, which makes it easy for the neck-hanging bone conduction headphones to separate from the charging stand, resulting in charging disconnection. Therefore, the charging stand and the neck-hanging bone conduction headphones can only be placed on a stable desktop for charging, and cannot be placed in a messy space such as a backpack, resulting in low charging stability.

The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0059] In one embodiment of the present application, a bone conduction headset charging stand is provided, including a shell, a rechargeable battery, two charging contacts and a charging circuit board. The two opposite sides of the shell are respectively provided with a placement groove, and the two placement grooves are symmetrically arranged with each other, and each placement groove is used to place a bone conduction headset. The rechargeable battery is placed in a cavity formed around the shell. Each charging contact is respectively arranged in a placement groove, and is used to contact the bone conduction headset in the placement groove. The charging circuit board is placed in the cavity and electrically connected to the charging contacts and the rechargeable battery. The charging circuit board can control the rechargeable battery to charge the bone conduction headset after the charging contacts contact the bone conduction headset.

[0060] The above-mentioned bone conduction earphone charging stand can be suitable for independent or neck-hanging bone conduction earphones. Two independent bone conduction earphones can be easily accommodated and fixed through the placement grooves on both sides of the shell, thereby improving the convenience of taking and placing the bone conduction earphones. At the same time, through the symmetry of the two placement grooves, the bone conduction earphone charging stand is located between the neck-hanging bone conduction earphones, thereby improving the charging stability. The purpose of charging the bone conduction earphones is then achieved through the charging circuit board, charging contacts and rechargeable batteries.

[0061] In one embodiment of the present application, a bone conduction earphone kit is also provided, including a bone conduction earphone assembly and the above-mentioned bone conduction earphone charging stand. The bone conduction earphone assembly includes two bone conduction earphones, each bone conduction earphone includes an earphone battery, an earphone contact and an earphone circuit board that are electrically connected. After the bone conduction earphone is placed in the placement slot, the earphone contact contacts the charging contact so that the rechargeable battery charges the earphone battery, and the earphone circuit board can turn off the audio transmission function of the bone conduction earphone after the earphone contact contacts the charging contact, and start the audio transmission function of the bone conduction earphone after the earphone contact disconnects from the charging contact. The above-mentioned bone conduction earphone kit also achieves the purpose of improving charging stability and portability through the above-mentioned bone conduction earphone charging stand, and achieves the purpose of automatically starting the bone conduction earphone assembly after leaving the bone conduction earphone charging stand.

[0062] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0063] See also Figures 1 to 4In one embodiment of the present application, a bone conduction headset charging stand 100 is provided for charging bone conduction headsets. The bone conduction headset charging stand 100 includes a shell 10. Two opposite sides of the shell 10 respectively form a placement groove 10a. Each placement groove 10a is used to place and fix a bone conduction headset, that is, the two placement grooves 10a together accommodate a pair of bone conduction headsets. The two placement grooves 10a are arranged symmetrically along a mirror plane. In some embodiments, the bone conduction headset charging stand 100 is used to charge independent bone conduction headsets. Since the placement groove 10a is an open groove connected to the outside and there is no cover, the bone conduction headset can be conveniently taken out without flipping the cover, thereby improving the charging portability of the bone conduction headset. In other embodiments, the bone conduction earphone charging stand 100 is used to charge neck-hanging bone conduction earphones. Since the two seating grooves 10a are provided on opposite sides of the shell 10 and are symmetrically arranged, the bone conduction earphone charging stand 100 can be located between the neck-hanging bone conduction earphones, so that the neck-hanging bone conduction earphones can clamp the bone conduction earphone charging stand 100 by the elasticity of the collar, that is, on the basis of fixing the bone conduction earphones in the seating grooves 10a, the two bone conduction earphones can further clamp the bone conduction earphone charging stand 100 by the elasticity of the collar, thereby improving the connection stability between the bone conduction earphone charging stand 100 and the neck-hanging bone conduction earphones, and then improving the charging stability.

[0064] In some embodiments of the bone conduction headset charging stand 100 for charging neck-hanging bone conduction headsets, preferably, the distance between the two placement grooves 10a near the bottom of the housing 10 is smaller than the distance between the two placement grooves 10a near the top of the housing 10, that is, the distance between the two placement grooves 10a is roughly distributed to gradually increase from the bottom of the housing 10 to the top of the housing 10, that is, the two placement grooves 10a have a certain angle in the extension direction from the bottom of the housing 10 to the top of the housing 10. Since the two ends of the collar of the neck-hanging bone conduction headset have a certain angle to move closer in a relaxed state, the two bone conduction headsets at the ends of the collar also have a certain angle in a relaxed state, that is, the ends of the two bone conduction headsets away from the collar are close to each other and the ends connected to the collar are far away, so the angle between the two placement grooves 10a can better match the bone conduction headsets at both ends of the collar, making the connection between the neck-hanging bone conduction headset and the bone conduction headset charging stand 100 more convenient and natural, and there is no need to deliberately adjust the distance, position or angle between the bone conduction headsets at both ends of the collar during charging, thereby improving the convenience of charging.

[0065] See also Figure 2 and Figure 3The bone conduction earphone charging stand 100 also includes a rechargeable battery 20, two charging contacts 30 and a charging circuit board 40. The rechargeable battery 20 is placed in a cavity 10b formed around the housing 10. A charging contact 30 is provided in each placement slot 10a. The charging contact 30 is used to contact the bone conduction earphone in the placement slot 10a. The charging circuit board 40 is placed in the cavity 10b and electrically connects the charging contact 30 and the rechargeable battery 20. The charging circuit board 40 can control the rechargeable battery 20 to charge the bone conduction earphone after the charging contact 30 contacts the bone conduction earphone that needs to be charged.

[0066] In some embodiments, the bone conduction headset charging stand 10 further includes a magnetic member 50. The magnetic member 50 is located in the cavity 10b and is disposed on the inner wall of the housing 10 corresponding to the placement groove 10a. The magnetic member 50 is used to magnetically attract the headset magnet 240 (such as Figure 7 ), so that the bone conduction earphone can be more stably fixed in the placement groove 10a. As an exemplary example, the magnetic member 50 is a rectangular magnet.

[0067] See also Figure 4 In some embodiments, a convex wall 10d is provided on the inner side wall of the shell 10 corresponding to the placement groove 10a. The convex wall 10d surrounds a fixed groove 10e. The shell 10 is provided with a through hole 10c on the groove wall of each fixed groove 10e. The fixed groove 10e is used to accommodate the charging contact 30 and the magnetic member 50 together. The charging contact 30 extends out of the shell 10 through the through hole 10c to contact the bone conduction earphone. As an illustrative example, the charging contact 30 is a telescopic contact, and each charging contact 30 includes a positive telescopic contact rod and a negative telescopic contact rod. Two through holes 10c are provided on the groove wall of each fixed groove 10e to expose the positive and negative telescopic contact rods respectively.

[0068] See also Figure 2 and Figure 3 In some embodiments, the bone conduction headset charging stand 100 further includes a wireless charging coil 60. The wireless charging coil 60 is disposed in the cavity 10b and is disposed near the bottom of the housing 10. The wireless charging coil 60 is electrically connected to the charging circuit board 40, and is used to cooperate with an external wireless charging stand to wirelessly charge the rechargeable battery 20. As an illustrative example, the wireless charging coil 60 is in the shape of a sheet, the rechargeable battery 20 is in the shape of a rectangular plate, and the charging circuit board 40 is in the shape of a plate, wherein the extension planes where the charging circuit board 40, the rechargeable battery 20 and the wireless charging coil 60 are located are perpendicular to each other, so as to save space in the bone conduction headset charging stand 100 and reduce the volume and weight of the bone conduction headset charging stand 100.

[0069] In some embodiments, the bone conduction headset charging stand 100 further includes an interface 70. The interface 70 is electrically connected to the charging circuit board 40. A clearance hole 10f is provided on the top of the housing 10. The clearance hole 10f is used to expose the interface 70. The interface 70 is used to connect an external power source to charge the rechargeable battery 20. In other embodiments, the clearance hole 10f may also be provided at the bottom of the housing 10 or at other locations.

[0070] In some embodiments, the bone conduction headset charging station 100 further includes a light guide column 80. The housing 10 is provided with a light-transmitting hole 10g. One end of the light guide column 80 is connected to a lamp (not shown) on the charging circuit board 40, and the other end extends out of the light-transmitting hole 10g, which is used to transmit the light emitted by the lamp to the outside of the housing 10, so as to distinguish the state of the bone conduction headset charging station 100. As an illustrative example, there are three light guide columns 80, which respectively guide the light of three lamps. The charging circuit board 40 can control the three lamps and the light guide column 80 to display the power or power on / off status by flashing or being always on.

[0071] In some embodiments, the bone conduction headset charging stand 100 further includes a button 90. The housing 10 is provided with a button hole 10h. The button 90 is electrically connected to the charging circuit board 40 and extends out of the housing 10 through the button hole 10h. The button 90 is used to control the charging circuit board 40, for example, by long pressing or tapping to control the bone conduction headset to enter a pairing state or restore factory settings.

[0072] In some embodiments, the light guide column 80 and the button 90 are both located on the same side of the housing 10, and the housing 10 has a decorative sheet 11 on the side. The decorative sheet 11 is embedded in the front of the housing 10 and can expose the light guide column 80 and the button 90. In order to improve the aesthetics, the decorative sheet 11 is in a symmetrical inverted trapezoidal shape, the button 90 is in an oblong shape, the light guide column 80 is circular, and the axes of the light guide column 80 and the button 90 coincide with the axis of the decorative sheet 11 to be symmetrically arranged.

[0073] It is understandable that in some embodiments, for easy installation, the housing 10 includes two mirror-symmetrical left and right halves, and after fixing other components such as the charging circuit board 40 to one half by screws, the other half is fixed by screws to form a complete bone conduction headset charging stand 100. In addition, in order to save space, the light guide 80 and the button 90 are distributed on the front side of the bone conduction headset charging stand 100, and the rechargeable battery 20 is close to the back side of the bone conduction headset charging stand 100 to balance the weight and reduce the volume.

[0074] In some embodiments, avoidance grooves 12 are respectively provided on two opposite sides of the top of the shell 10 , and the avoidance grooves 12 are used to ensure a certain gap between the shell 10 and the bone conduction earphone to facilitate removing the bone conduction earphone from the shell 10 .

[0075] See also Figures 5 to 7In one embodiment of the present application, a bone conduction earphone kit 300 is also provided, including a bone conduction earphone assembly 200 and a bone conduction earphone charging stand 100. The bone conduction earphone assembly 200 includes two bone conduction earphones 200a, each bone conduction earphone 200a includes an earphone battery 210, an earphone contact 220 and an earphone circuit board 230 which are electrically connected. When the bone conduction earphone 200a is placed in the placement slot 10a, the earphone contact 220 can contact the charging contact 30, so that the rechargeable battery 20 charges the earphone battery 210. It is worth noting that the earphone circuit board 230 can turn off the audio transmission function of the bone conduction earphone 200a after the earphone contact 220 contacts the charging contact 30 (that is, the bone conduction earphone assembly 200 automatically turns off when charging), and start the audio transmission function of the bone conduction earphone 200a after the earphone contact 220 is disconnected from the charging contact 30 (that is, the bone conduction earphone assembly 200 automatically turns on after leaving the bone conduction earphone charging stand 100).

[0076] In some embodiments, the bone conduction earphone assembly 200 further includes a neck hanging portion 200b. The two bone conduction earphones 200a are symmetrically arranged at the two ends of the neck hanging portion 200b. The neck hanging portion 200b facilitates wearing the bone conduction earphone assembly 200 on the neck. The neck hanging portion 200b is arc-shaped and elastic, so that the two bone conduction earphones 200a always have a tendency to approach each other. When the bone conduction earphone charging stand 100 charges the bone conduction earphone assembly 200, the bone conduction earphone charging stand 100 is located between the two bone conduction earphones 200a, and the neck hanging portion 200b can make the two bone conduction earphones 200a have a certain clamping force on the bone conduction earphone charging stand 100 through elasticity, thereby improving the connection stability between the bone conduction earphone charging stand 100 and the bone conduction earphone 200a.

[0077] It can be understood that, when the bone conduction earphone charging stand 100 is light enough and small enough, the bone conduction earphone assembly 200 can be charged while being worn, that is, the bone conduction earphone assembly 200 and the bone conduction earphone charging stand 100 are hung on the neck together, and because the bone conduction earphone charging stand 100 is located between the two bone conduction earphones 200a, it will not affect the wearing comfort of the hanging neck 200b, so there is no need to remove the bone conduction earphone assembly 200 from the neck for charging, thereby improving the charging portability.

[0078] In some embodiments, each bone conduction headset 200a includes a functional portion 200c and an extension portion 200d connected to each other. The functional portion 200c is used to generate vibrations of a specific frequency to transmit audio through bone conduction. The extension portion 200d is used to connect the functional portion 200c and the neck hanging portion 200b. The placement slot 10a includes a first slot 10a1 and a second slot 10a2 (such as Figure 1). The shape of the first groove 10a1 is similar to (matches) the shape of the functional part 200c, and is used to accommodate the functional part 200c. The shape of the second groove 10a2 is similar to (matches) the shape of the extension part 200d, and is used to accommodate the extension part 200d. The earphone contact 220 is arranged on the extension part 200d, and correspondingly, the charging contact 30 is arranged on the groove wall of the second groove 10a2. When the functional part 200c is placed in the first groove 10a1, the extension part 200d will automatically align and be placed in the second groove 10a2, and the charging contact 30 will automatically align and contact the earphone contact 220. As an illustrative example, the functional part 200c is roughly in the shape of a pancake, and the extension part 200d is roughly in the shape of a column.

[0079] It is understandable that, in other embodiments, the bone conduction earphone 200a may also be replaced by a speaker-type earphone, that is, the functional portion 200c is used to generate sound waves, and the structure of the bone conduction earphone charging stand 100 is also applicable to speaker-type earphones.

[0080] In summary, the bone conduction headset charging stand 100 can be applied to stand-alone or neck-hanging bone conduction headsets. The placement grooves 10a on both sides of the housing 10 can easily accommodate and fix two stand-alone bone conduction headsets, thereby improving the convenience of taking and placing the bone conduction headsets. At the same time, through the symmetry of the two placement grooves 10a, the bone conduction headset charging stand 100 is located between the neck-hanging bone conduction headsets, thereby improving the purpose of charging stability. The purpose of charging the bone conduction headset is achieved through the charging circuit board 40, the charging contacts 30 and the rechargeable battery 20. The bone conduction headset kit 300 also achieves the purpose of improving charging stability and portability through the bone conduction headset charging stand 100, and achieves the purpose of automatically starting the bone conduction headset assembly 200 after leaving the bone conduction headset charging stand 100.

[0081] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application and are not intended to be limiting of the present application. As long as they are within the spirit and scope of the present application, appropriate changes and modifications to the above embodiments are within the scope of the present application.
