DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0043] Please also refer to Figures 1 to 4 The embodiment of the present application provides a charging cable 100 and an open-ear headphone device 1000. The open-ear headphone device 1000 includes the charging cable 100 and open-ear headphones 200. The open-ear headphones 200 include a battery 210, two charging pins 220, a transmitter module 240, a control module 250, and a sound module 230. The charging pins 220, the battery 210, the sound module 230, the transmitter module 240, and the control module 250 are electrically connected, and the sound module 230 at least partially extends out of the charging base 120. It should be noted that the open-ear headphone device 1000 is typically provided with two open-ear headphones 200, corresponding to the left and right ears of the user.

[0044] There are many types of batteries 210. The battery 210 can be a rechargeable button battery 210, the battery 210 can also be a soft-pack lithium battery 210, or the battery 210 can also be a needle-type battery 210, which is not specifically limited here. The two charging needles 220 are respectively connected to the positive and negative poles of the battery 210. The shapes of the charging needles 220 can be many. The charging needles 220 can be cylindrical, the charging needles 220 can also be truncated cone-shaped, or the charging needles 220 can also be other shapes, which are not specifically limited here. Preferably, the surface of the charging needle 220 electrically connected to the charging base 120 is larger than the surface of the charging needle 220 connected to the battery 210, thereby ensuring that the charging base 120 and the charging needle 220 can be accurately electrically connected. The charging needle 220 is made of many materials. The charging needle 220 can be made of an alloy material, the charging needle 220 can be made of a brass material, or the charging needle 220 can be made of other conductive materials, which are not listed here one by one.

[0045] Open-ear headphones 200 can be categorized as air conduction headphones, bone conduction headphones, and combined bone conduction and air conduction headphones, depending on the sound production module. Bone conduction headphones can be either shrapnel-type or vibration motor-type, though this is not specifically limited here. The sound production module of combined bone conduction and air conduction headphones can be composed of a shrapnel-type bone conduction vibrator covered with an air conduction diaphragm, or a bone conduction vibrator and an air conduction speaker.

[0046] The open earphone 200 is matched with an external device through the transmitting module 240 , and the external device can send instructions to the control module 250 through the transmitting module 240 , so that the sound module 230 plays the specified audio.

[0047] The charging cable 100 includes a cable body 110, a charging base 120 and a charging plug 130. The cable body 110 has a charging end 111 and a connecting end 112. The charging base 120 is respectively installed on the two charging ends 111 and is electrically connected to the charging ends 111. The charging base 120 is used to electrically connect to the open-back headphones 200. The charging plug 130 is installed on the connecting end 112 and is electrically connected to the connecting end 112. The charging plug 130 is used to electrically connect to an external power supply. After the charging plug 130 is electrically connected to the external power supply, the current passes through the cable body 110 and the charging base 120 in sequence to charge the open-back headphones 200.

[0048] The wire body 110 has the ability to conduct electricity. In order to increase the service life of the wire body 110, the outer periphery of the wire body 110 is wrapped with an insulating layer. The insulating layer can be made of PVC material, nylon braided material, or silicone material, which are not listed here one by one.

[0049] There are many ways to connect the charging cradle 120 to the charging terminal 111. The charging cradle 120 and the charging terminal 111 can be snap-fitted, plug-fitted, or snap-fitted, all of which are not listed here. There are also many ways to connect the charging cradle 120 and the open-back headphones 200. The charging cradle 120 and the open-back headphones 200 can be magnetically coupled, plug-fitted, or snap-fitted, all of which are not specifically limited here.

[0050] It should be noted that the charging cable 100 can be provided with a charging seat 120, and one of the open-back headphones 200 can be charged through the charging seat 120; the charging cable 100 can also be provided with two charging seats 120, and the cable body 110 is provided with two charging ends 111, which are arranged in a Y shape. The two charging seats 120 are arranged in a one-to-one correspondence with the two charging ends 111. When both open-back headphones 200 are out of power, the two open-back headphones 200 can be installed in the two charging seats 120 respectively, so that the charging cable 100 can charge the two open-back headphones 200 at the same time, and the Y-shaped arrangement of the cable body 110 does not affect the user wearing two open-back headphones 200.

[0051] There are many types of charging plugs 130, including USB, Type-C, and two-pin plugs, all of which are not specifically limited here. There are many ways to connect the charging plug 130 to the connection end 112, including snap-fit, plug-fit, and snap-fit, all of which are not listed here.

[0052] After the charging plug 130 is connected to an external power source and the open-back earphones 200 are connected to the charging base 120, current flows through the charging plug 130, the cable, and the charging base 120 to charge the battery 210 of the open-back earphones 200. At this point, the user can move the two charging bases 120 to wear the open-back earphones 200 on their ears. Due to the high maneuverability of the cable 110, the movement of the charging base 120 is not affected. Preferably, the sound module 230 at least partially extends out of the charging base 120. This allows the user to wear the open-back earphones 200 on their ears by extending the portion of the open-back earphones 200 that extends out of the charging base 120, allowing the user to continue using the open-back earphones 200.

[0053] The charging cable 100 in the embodiment of the present application is connected to an external power source via a charging plug 130 and then charges the open-ear headphones 200 via a charging dock 120. The cable body 110 is manipulated to adjust the position between the connection end 112 and the two charging ends 111. This allows the open-ear headphones 200 to be electrically connected to the charging dock 120 without having to be placed in a fixed position, thereby not affecting user use and thus improving the user experience. Furthermore, the structure of the cable body 110 is more convenient for users to carry than a charging case.

[0054] Please also refer to Figures 2 to 3In some embodiments of the present application, the charging stand 120 includes a shell 121 and two charging contacts 122. The surface of the shell 121 away from the charging end 111 is recessed with a receiving groove 121a, and the open-earphones 200 are pluggable in the receiving groove 121a; the two charging contacts 122 are both arranged in the receiving groove 121a and are electrically connected to the charging end 111 for electrical connection with the open-earphones 200. With this arrangement, the notch of the accommodating groove 121a and the charging end 111 of the cable 110 are respectively located on two opposite surfaces of the shell 121, thereby preventing interference between the cable 110 and the open-earphone 200 when the open-earphone 200 is placed in the accommodating groove 121a. At the same time, the accommodating groove 121a and the open-earphone 200 are pluggable and compatible, so that the accommodating groove 121a can limit the open-earphone 200, so that the open-earphone 200 can be stably located in the accommodating groove 121a, avoiding shaking that causes the open-earphone 200 to detach from the accommodating groove 121a, thereby ensuring the stability of the electrical connection between the charging base 120 and the open-earphone 200, and the two charging contacts 122 are arranged in the accommodating groove 121a, so that when the open-earphone 200 is placed in the accommodating groove 121a, the contact of the charging contacts 122 will be blocked by the open-earphone 200, thereby preventing the user from touching the charging contacts 122 during charging and causing electric shock.

[0055] The shape of the accommodating groove 121a varies. The accommodating groove 121a can be cylindrical or square. Any shape is acceptable, as long as it fits the portion of the open-back earphone 200 that extends into it. There are no specific limitations here. When there are two charging stations, preferably, the portions of the two open-back earphones 200 that extend into the corresponding accommodating grooves 121a have different shapes. The two accommodating grooves 121a correspond to the shapes of the two open-back earphones 200 that extend into them. This ensures that the open-back earphones 200 can only be placed in the corresponding accommodating grooves 121a.

[0056] For details, please refer to Figures 2 to 3The shell 121 includes an inner shell 121b and an insulating cover 121c. The inner shell 121b is provided with a accommodating groove 121a. The surface of the insulating cover 121c away from the charging terminal 111 is recessed with a mounting groove 121d. The bottom of the mounting groove 121d is penetrated by a mounting hole. The inner shell 121b is installed in the mounting groove 121d. The lower surface of the inner shell 121b and the bottom of the mounting groove 121d are surrounded by a mounting cavity 121e. The charging terminal 111 extends into the mounting cavity 121e through the mounting hole and is connected to the inner shell 121b and electrically connected to the charging contact 122. In this arrangement, the charging contacts 122 and the charging end 111 of the line are wrapped by the insulating cover 121c, thereby preventing the user from touching the charging contacts 122 and causing electric shock during charging. At the same time, the charging contacts 122 are first installed on the inner shell 121b, and then the charging end 111 is passed through the mounting hole and connected to the inner shell 121b, and electrically connected to the two charging contacts 122. Then, the wire body 110 is pulled to install the inner shell 121b in the mounting groove 121d, which facilitates the assembly of the charging cable 100.

[0057] Considering that there is a circuit connection in the installation cavity 121e formed by the inner shell 121b and the insulating cover 121c, the material of the inner shell 121b needs to be an insulating material to prevent the inner shell 121b from affecting the circuit connection and causing a circuit short circuit. The inner shell 121b can be made of polypropylene material, the inner shell 121b can also be made of high-density polyethylene material, or the inner shell 121b can be made of other insulating materials, which are not specifically limited here. The inner shell 121b has many shapes. The inner shell 121b can be cylindrical, the inner shell 121b can be square, or the inner shell 121b can be other shapes, which are not specifically limited here. Preferably, the shape of the inner shell 121b is the same as the shape of the installation groove 121d, so that the outer peripheral wall of the inner shell 121b and the groove wall of the installation groove 121d are interference fit to seal the installation cavity 121e and prevent the external environment from affecting the circuit.

[0058] The insulating cover 121c can be made of a variety of materials. The insulating cover 121c can be made of polypropylene, high-density polyethylene, or other insulating materials, without specific limitations herein. The mounting groove 121d and the inner shell 121b can be snap-fitted, plug-fitted, or connected by screws, without specific limitations herein.

[0059] There are many ways to connect the charging terminal 111 and the inner shell 121b. The charging terminal 111 and the inner shell 121b can be snap-fitted, or plug-fitted. The charging terminal 111 and the inner shell 121b can also be connected by setting a limit plate, which is connected to the inner shell 121b. The charging terminal 111 is set between the limit plate and the inner shell 121b, so that the limit plate and the inner shell 121b clamp the charging terminal 111 to achieve a fixed effect. No specific limitation is made here.

[0060] Further, please also refer to Figures 2 to 3 The charging cable 100 further includes a controller 140, which is mounted in each mounting cavity 121e and electrically connected to the two charging contacts 122 and the charging terminal 111. The controller 140 is used to control the current output to the open-ear headphones 200. It is understood that when there are two charging stations, there are two controllers. Each of the two charging stations 120 is formed with a mounting cavity 121e and is connected to a charging terminal 111. The two controllers 140 are provided in a one-to-one correspondence with the two charging stations 120. The controllers 140 are mounted in the mounting cavities 121e of the corresponding charging stations 120 and are electrically connected to the two charging contacts 122 in the corresponding charging stations 120, so that the charging terminal 111 connected to the corresponding charging station 120 is electrically connected to the corresponding two charging contacts 122 through the controller 140.

[0061] With this configuration, the controller 140 controls the current input to the open-back earphones 200, thereby protecting the open-back earphones 200. It should be noted that the controller 140 has various functions. When the current passing through the controller 140 is too high, the controller 140 can reduce the current received to ensure the current level of the input to the open-back earphones 200, or it can disconnect the electrical connection with the open-back earphones 200 to protect the open-back earphones 200. These functions are not listed here.

[0062] Controller 140 can be a single-chip microcomputer, a PWM controller 140, a microprocessor, or other devices. There are many ways to install controller 140 in mounting cavity 121e. Controller 140 can be installed in mounting cavity 121e by screw connection, by snap connection, or by plug-in connection, without specific limitations here. Mounting cavity 121e is formed by the lower surface of inner shell 121b and the bottom of mounting groove 121d. Controller 140 can be installed on inner shell 121b or on mounting groove 121d, without specific limitations here.

[0063] See also Figure 2In some embodiments of the present application, two positioning posts 121f are provided on the wall of the mounting cavity 121e, near or away from the receiving groove 121a. The controller 140 is provided with two positioning holes 141. The two positioning posts 121f cooperate with the two positioning holes 141 to limit the position of the controller 140. In this arrangement, the two positioning posts 121f and the two positioning holes 141 cooperate to limit the position of the controller 140, thereby preventing the controller 140 from moving within the mounting cavity 121e and colliding with the cavity wall of the mounting cavity 121e and being damaged.

[0064] Preferably, the charging seat 120 also includes a limiting member 125, the inner shell 121b is provided with a accommodating groove 121a, and two positioning columns 121f are provided at one end of the inner shell 121b extending into the installation groove 121d. The limiting member 125 is installed at the end of the inner shell 121b extending into the installation groove 121d, and the controller 140 is installed between the inner shell 121b and the limiting member 125. In this arrangement, the controller 140 is limited by the limiting member 125, thereby fixing the controller 140, which is convenient for subsequent pulling of the wire body 110 to install the inner shell 121b in the installation groove 121d, thereby facilitating the assembly of the charging cable 100.

[0065] Please also refer to Figures 2 to 3 In some embodiments of the present application, the charging base 120 further includes a first magnetic member 123 mounted on the housing 121. The first magnetic member 123 is configured to magnetically attract the open-back earphones 200. This arrangement allows the first magnetic member 123 to attract the open-back earphones 200, thereby ensuring that the open-back earphones 200 remain stably positioned on the charging base 120 and preventing the open-back earphones 200 from being detached from the charging base 120 due to shaking.

[0066] It should be noted that the first magnetic member 123 can be magnetically coupled to the metal shell of the open-ear headphones 200, or the first magnetic member 123 can be magnetically coupled to the second magnetic member 260 inside the open-ear headphones 200, and no specific limitation is given here. The first magnetic member 123 can be located on the same side of the two charging contacts 122, or the first magnetic member 123 can be located between the two charging contacts 122. Preferably, the first magnetic member 123 is located between the two charging contacts 122. This allows the open-ear headphones 200 to maintain balance between the two charging contacts 122 when the first magnetic member 123 attracts the open-ear headphones 200, thereby preventing the open-ear headphones 200 from tilting and causing one of the charging contacts 122 to disconnect from the open-ear headphones 200.

[0067] Further, please also refer to Figures 2 to 3The charging base 120 also includes two charging springs 124. One end of each charging spring 124 extends into the receiving groove 121a and is provided with an elastic support portion 124a. The other end of each charging spring 124 is electrically connected to the charging terminal 111. The elastic support portions 124a are provided with charging contacts 122. The two elastic support portions 124a extend at least in a direction toward each other. This arrangement allows the two elastic support portions 124a to compress the open-ear headphones 200 under the action of elastic force, thereby improving the stability of the electrical connection between the charging contacts 122 and the open-ear headphones 200. At the same time, the two elastic support portions 124a can also clamp and position the open-ear headphones 200.

[0068] Please also refer to Figure 2 and Figure 4 In some embodiments of the present application, the open-earphone device 1000 further includes two second magnetic members 260, which are spaced apart, and the two charging pins 220 are located between the two second magnetic members 260. With this arrangement, the two second magnetic members 260 cooperate with the charging base 120 to adsorb the open-earphone 200 onto the charging base 120, thereby allowing the open-earphone 200 to be stably positioned on the charging base 120, preventing the open-earphone 200 from being separated from the charging base 120 due to shaking. At the same time, the charging pin 220 is located between the two second magnetic members 260, so that the connection around the charging pin 220 and the charging base 120 is more stable, thereby improving the stability of the electrical connection between the charging pin 220 and the charging base 120.

[0069] The second magnetic member 260 can be magnetically coupled to a metal component within the charging base 120, or it can be magnetically coupled to the first magnetic member 123 within the charging base 120, without specific limitation herein. Preferably, the charging base 120 is provided with the first magnetic member 123, and the projection area of ​​the first magnetic member 123 toward the second magnetic member 260 is greater than or equal to the projection area of ​​the second magnetic member 260. This allows the first magnetic member 123 to better sense the second magnetic member 260 and magnetically couple with the second magnetic member 260 when the open-ear headphones 200 are placed on the charging base 120.
