[0037] See also Figure 1 、 Figure 2 and Figure 3 The earphone button structure 200 of the present invention is used in the earphone charging compartment 100. The earphone button structure 200 includes a light-guiding button 20, a circuit board 30, and a light-emitting element 40. The light-guiding button 20 includes a light-guiding portion 21 and a button portion 22 connected to the light-guiding portion 21. The light-guiding portion 21 is used to transmit light, and one end of the button portion 22 is connected to the light-guiding portion 21; the circuit board 30 is connected to the other end of the button portion 22; and the light-emitting element 40 is used to emit light toward the light-guiding portion 21.

[0038] In the headphone button structure 200 of the embodiment of the present invention, since the light-guiding button 20 integrates the functions of light-guiding and button, the user can not only perform basic operations such as adjusting the volume, pausing or playing music through the light-guiding button 20, but also can intuitively see the status of the headphone through the light guided by the light-guiding button 20, such as battery information, Bluetooth pairing status, etc., thereby providing a visual feedback mechanism and improving the functionality of the headphone button structure 200.

[0039] Specifically, the earphone may be a Bluetooth earphone, such as an open-ear Bluetooth earphone or an in-ear Bluetooth earphone.

[0040] The light-guiding key 20 is a key integrated with a light-guiding function. The light-guiding portion 21 is a portion of the light-guiding key 20 for guiding light.

[0041] The key portion 22 is used to implement the key function of the light-guiding key 20. The key portion 22 can be integrally formed with the light-guiding portion 21, or it can be formed separately from the light-guiding portion 21. For example, the key portion 22 and the light-guiding portion 21 can be manufactured separately and connected together by bonding. The key portion 22 can include a metal dome key, a membrane key, or the like.

[0042] The circuit board 30 is used for the transmission and control of electronic signals. It can be a printed circuit board 30 or a flexible circuit board 30, and can be mounted with electronic components such as a control chip, resistors, and capacitors. In response to force applied by the button portion 22, the circuit board 30 generates electronic signals to implement the electronic functions of the headphone button structure 200, such as battery display and Bluetooth pairing.

[0043] The light-emitting element 40 is an electronic component for emitting light. It can be an LED (Light Emitting Diode) lamp, an EL (Electroluminescent wire) cold wire, or another type of light-emitting device. The light-emitting element 40 can be electrically connected to the circuit board 30. The light-emitting element 40 can use the power provided by the circuit board 30 and emit light under the control of the circuit board 30.

[0044] During use, the button portion 22 applies varying forces to the circuit board 30, causing the circuit board 30 to receive different commands. Based on these commands, the circuit board 30 controls the light emitting element 40 to emit light of varying colors, brightness, or frequencies, enabling the light guide portion 21 to provide varying visual feedback, thereby enhancing the functionality of the headphone button structure 200.

[0045] See also Figure 1 、 Figure 2 and Figure 3The earphone charging case 100 of the present invention includes a housing 10, a light guide button 20, a circuit board 30 and a light-emitting component 40. The housing 10 is provided with a first through hole 11; the light guide button 20 includes a light guide portion 21 and a button portion 22 connected to the light guide portion 21. The light guide portion 21 is provided in the first through hole 11. The light guide portion 21 is used to transmit light. One end of the button portion 22 is connected to the light guide portion 21; the circuit board 30 is connected to the other end of the button portion 22; the light-emitting component 40 is used to emit light toward the light guide portion 21.

[0046] In the headphone charging compartment 100 of the present invention, the light guide button 20 integrates the functions of light guide and button. This reduces the space occupied by the additional light guide structure, thereby improving the space utilization of the headphone charging compartment 100. Moreover, since the integrated design of light guide and button eliminates the need for a separate light guide structure, the number of molds required and material costs during the manufacturing process are reduced. In addition, the simplified structural design also helps to reduce the number of assembly steps in the production process, thereby reducing production costs and improving production efficiency.

[0047] Specifically, the earphone charging compartment 100 can be used to charge the earphones. The housing 10 refers to the component that constitutes the external structure of the earphone charging compartment 100 and is used to protect the components inside the earphone charging compartment 100. The housing 10 can be made of plastic, metal or synthetic materials.

[0048] The first through hole 11 may be a through hole opened on the housing 10. The shape of the first through hole 11 may be a regular shape such as a circle or a square, or may be an irregular shape.

[0049] The light guide portion 21 may be disposed in the housing 10 and extend from the interior of the housing 10 to the first through hole 11. The light guide portion 21 may be flush with the outer surface of the housing 10, or may be protruding from or recessed in the outer surface of the housing 10.

[0050] The light guide 21 and the first via 11 may be connected with a clearance fit, which can reduce the probability of friction between the light guide 21 and the housing 10 during movement, thereby increasing the service life of the light guide 21 and the housing 10. The light guide 21 can be made of a light-transmitting material such as polycarbonate resin and polystyrene.

[0051] The button portion 22 may be disposed in the housing 10. The button portion 22 may be spaced apart from the first via hole 11. The button portion 22 may be located in the extending direction of the first via hole 11, which may simplify the structure of the light-guiding button 20 and reduce manufacturing costs.

[0052] During use, the user can press the light-guiding button 20 at different times to cause the circuit board 30 to receive different instructions. Based on these instructions, the circuit board 30 can control the light-emitting element 40 to emit light of different colors, brightness, or frequencies, allowing the user to determine the current operating status of the headphone charging compartment 100, such as battery level information and Bluetooth pairing status. Of course, the light-emitting element 40 can also be activated by other means, not limited to user pressing operations.

[0053] See also Figure 3 In some embodiments, the earphone charging compartment 100 further includes an elastic member 50 , which is disposed on the circuit board 30 , and an end of the elastic member 50 away from the circuit board 30 elastically abuts against one side of the light guide portion 21 .

[0054] Thus, by providing the elastic member 50 on the circuit board 30, the light-guiding key 20 can be supported and fixed, thereby improving the stability of the light-guiding key 20 during the pressing process. In addition, one end of the elastic member 50 elastically abuts against one side of the light-guiding portion 21. The elastic member 50 can provide a certain amount of tactile feedback, giving the user a better experience when operating the light-guiding key 20, and can also confirm whether the operation is successful through tactile feedback.

[0055] Specifically, the elastic member 50 can be made of an elastic material such as silicone or rubber. The elastic member 50 can be disposed within the housing 10. The elastic member 50 can be attached to the circuit board 30 by bonding, welding, or pressing. The elastic member 50 can be located on a side of the circuit board 30 proximate to the first via 11. The elastic member 50 is configured to support the light guide 21. One end of the elastic member 50 contacts a side of the light guide 21 and can elastically deform to abut against the light guide 21, providing support.

[0056] When the user presses the light-guiding key 20, the light-guiding portion 21 exerts force on the elastic member 50, causing the elastic member 50 to deform elastically. The deformation of the elastic member 50 provides a certain amount of movement space for the light-guiding portion 21, allowing the light-guiding key 20 to be pressed.

[0057] See also Figure 3 In some embodiments, the elastic member 50 and the circuit board 30 define a receiving cavity 101 , the light emitting member 40 is disposed in the receiving cavity 101 , and at least a portion of the light guide portion 21 extends into the receiving cavity 101 .

[0058] In this way, the accommodating cavity 101 can effectively control the propagation direction of light, so that the light emitted by the light-emitting element 40 is mainly transmitted through the light-guiding portion 21, rather than being scattered in other unintended directions, thereby preventing light leakage and improving the energy efficiency of the light-emitting element 40. The accommodating cavity 101 can provide additional protection for the light-emitting element 40, preventing the ingress of dust and other contaminants, thereby extending the service life of the light-emitting element 40.

[0059] Specifically, the accommodating cavity 101 can be formed by the elastic member 50 and two adjacent side surfaces of the circuit board 30. The accommodating cavity 101 can be a semi-enclosed space enclosed by the elastic member 50 and the circuit board 30. The accommodating cavity 101 can be used to accommodate components such as the light-emitting member 40 and the button portion 22.

[0060] At least a portion of the light guide portion 21 extending into the accommodating cavity 101 may be disposed close to the light emitting element 40 to reduce the loss of light emitted by the light emitting element 40 during propagation and improve light collection efficiency.

[0061] See also Figure 3 、 Figure 4 、 Figure 5 and Figure 6 In some embodiments, the elastic member 50 is provided with a second through hole 51, and the light guide portion 21 includes a first light guide 210 and a second light guide 211. The first light guide 210 is provided through the first through hole 11, and the second light guide 211 protrudes from a side of the first light guide 210 away from the first through hole 11. The second light guide 211 is provided through the second through hole 51 and is connected to the button portion 22.

[0062] In this way, during the assembly process, the light guide portion 21 can be positioned through the first via hole 11 and the second via hole 51 , which simplifies the assembly process.

[0063] Specifically, the second via hole 51 may be a through hole provided on the elastic member 50. The shape of the second via hole 51 may be a regular shape such as a circle or an ellipse, or may be an irregular shape.

[0064] The first light guide 210 may be an exposed portion of the light guide portion 21. The first light guide 210 may be in contact with a user. The first light guide 210 may move under the action of an external force to drive the light guide button 20 to move as a whole. The second light guide 211 may be a portion of the light guide portion 21 located inside the housing 10. The first light guide 210 and the second light guide 211 may be integrally formed or separately formed. The shapes of the first light guide 210 and the second light guide 211 may be rod-shaped, tubular, columnar, or the like. The shape of the first light guide 210 may be the same as or different from the shape of the second light guide 211.

[0065] The first light guide 210 and the first via 11 may have a clearance fit, thereby reducing the probability of friction between the first light guide 210 and the elastic member 50, thereby extending the service life of the first light guide 210 and the elastic member 50. The second light guide 211 and the second via 51 may have a clearance fit, thereby reducing the probability of friction between the second light guide 211 and the elastic member 50, thereby extending the service life of the second light guide 211 and the elastic member 50.

[0066] The second light guide 211 and the button portion 22 can be connected by means of snapping, bonding, etc. When in use, the second light guide 211 moves and applies a force to the button portion 22, so that the button portion 22 is driven to move.

[0067] See also Figure 2 、 Figure 3 and Figure 4 In some embodiments, the housing 10 includes a first shell 12 and a second shell 13 detachably connected to the first shell 12 . The first shell 12 is provided with a first through hole 11 . The first shell 12 and the second shell 13 form an accommodating space 102 . The accommodating space 102 is connected to the first through hole 11 . The button portion 22 , the circuit board 30 , and the light-emitting element 40 are all disposed in the accommodating space 102 , and at least a portion of the light-guiding portion 21 extends into the accommodating space 102 .

[0068] Thus, by designing the housing 10 as a detachably connected first shell 12 and second shell 13, the earphone charging compartment 100 can be easily opened to maintain the button portion 22, circuit board 30, and light-emitting element 40. The accommodating space 102 provides additional protection for the button portion 22, circuit board 30, light-emitting element 40, and light guide portion 21, preventing the ingress of dust and other contaminants, thereby extending the service life of the earphone charging compartment 100.

[0069] Specifically, the first shell 12 and the second shell 13 can be detachably connected by a snap connection, a threaded connection, or a magnetic connection. The first shell 12 and the second shell 13 can also be connected by bonding. For example, the first shell 12 and the second shell 13 can be bonded by a soluble adhesive. When it is necessary to disassemble the first shell 12 and the second shell 13, the soluble adhesive can be dissolved using a chemical solvent such as alcohol or an adhesive remover.

[0070] The first shell 12 may be provided with one or more first via holes 11. For example, the number of the first via holes 11 is two and the two first via holes 11 are spaced apart.

[0071] The first shell 12 and the second shell 13 can both be shells with openings, and can be buckled or covered with each other to form an accommodating space 102 .

[0072] The accommodating space 102 can be disposed around the accommodating cavity 101. The accommodating space 102 can include one or more compartments. For example, the accommodating space 102 can include two compartments, and the circuit board 30 can be disposed in both compartments. The button portion 22, the light-emitting element 40, and at least a portion of the light-guiding portion 21 can be located in the same compartment.

[0073] See also Figure 6 、 Figure 7 、 Figure 8 and Figure 9In some embodiments, the first shell 12 includes a main body 120 and a mounting member 121 protruding from one side of the main body 120, the main body 120 is provided with a first through hole 11, the mounting member 121 is spaced apart from the first through hole 11, and the light guide portion 21 includes a first light guide 210 and a cantilever 212 protruding from one side of the first light guide 210, the first light guide 210 is passed through the first through hole 11, and the cantilever 212 is fixedly connected to the mounting member 121.

[0074] Thus, by providing the mounting member 121 on the first housing 12 and fixing the cantilever 212 of the light guide 21 to the mounting member 121, additional support can be provided for the light guide 21, thereby enhancing the stability of the light guide 21. Furthermore, the mounting member 121 can provide a positioning function during the installation of the light guide 21, which simplifies the assembly process.

[0075] Specifically, the body 120 may be a main contour-shaped portion of the first shell 12. The body 120 may be used to provide support for the mounting member 121.

[0076] The mounting member 121 may be in the shape of a block or a column. The mounting member 121 may be integrally formed with the body 120 or separately formed from the body 120. The mounting member 121 may extend from the first shell 12 toward the second shell 13. The mounting member 121 may be located within the accommodating space 102. The mounting member 121 may be located between the circuit board 30 and the body 120, with a gap between the mounting member 121 and the circuit board 30. This prevents interference between the mounting member 121 and the circuit board 30, thereby preventing the mounting member 121 from affecting the functionality of the circuit board 30.

[0077] The cantilever 212 can be fixedly connected to the mounting member 121 by interference fit, hot melt connection, etc. The cantilever 212 can be elastic, so that during the movement of the first light guide 210, the cantilever 212 can be elastically deformed and not easily fatigued and fractured, thereby improving the service life of the cantilever 212.

[0078] See also Figure 9 In some embodiments, the cantilever 212 is provided with a third through hole 2120 , the mounting member 121 is passed through the third through hole 2120 , and the diameter of the third through hole 2120 is smaller than the width of the mounting member 121 .

[0079] Thus, the third via 2120 allows for faster positioning of the cantilever 212 and the mounting member 121 during assembly, thereby improving assembly efficiency. The cantilever 212 can closely mate with the mounting member 121, reducing the likelihood of separation between the cantilever 212 and the mounting member 121 and thereby improving the stability of the cantilever 212.

[0080] Specifically, the third via hole 2120 may be a through hole formed on the cantilever 212. The third via hole 2120 may be in a regular shape such as a circle or an ellipse, or may be in an irregular shape. The third via hole 2120 and the mounting member 121 are in interference fit.

[0081] The cantilever 212 may be made of an elastic material. When the mounting member 121 passes through the third through hole 2120 , the cantilever 212 undergoes elastic deformation and returns to its original shape after assembly is completed, thereby closely fitting with the mounting member 121 .

[0082] See also Figure 3 In some embodiments, there are multiple light-emitting elements 40 , and the multiple light-emitting elements 40 are arranged at intervals.

[0083] In this way, the plurality of light-emitting elements 40 can increase the light luminance, thereby making the brightness of the light-guiding key 20 higher, thereby improving the visibility of the light-guiding key 20 .

[0084] Specifically, the number of light-emitting elements 40 can be two, three, four, or even more. The spacing between two adjacent light-emitting elements 40 can be equal or unequal. The multiple light-emitting elements 40 can be spaced apart along the length or width of the circuit board 30, or can be spaced apart along the circumference of the light-guiding key 20.

[0085] See also Figure 3 In some embodiments, a plurality of light emitting elements 40 are disposed on both sides of the light guide portion 21 , and the light emitting elements 40 on both sides of the light guide portion 21 are arranged symmetrically.

[0086] In this way, the symmetrically arranged light emitting elements 40 can evenly distribute light on both sides of the light guide portion 21 , avoiding the situation where one side is too bright and the other side is too dark, thereby improving the uniformity of the light emission of the light guide key 20 .

[0087] Specifically, the arrangement of the light-emitting elements 40 can be linear or matrix-like. For example, there are two light-emitting elements 40, each located on opposite sides of the light guide 21 and symmetrically arranged with respect to the light guide 21. For another example, there are four light-emitting elements 40, each spaced apart along the circumference of the light guide 21, forming a square, with the two opposing light-emitting elements 40 symmetrically arranged with respect to the light guide 21.

[0088] See also Figure 10 and Figure 11 In some embodiments, the earphone charging compartment 100 further includes a cover 60 , which is rotatably connected to the housing 10 and can move between a closed position and an open position. In the closed position, the cover 60 blocks the light guide button 20 , and in the open position, the light guide button 20 is exposed.

[0089] Thus, when the cover 60 is in the closed position, the cover 60 can shield the light-guiding key 20, thereby protecting the light-guiding key 20 and preventing it from being worn, thereby extending the service life of the light-guiding key 20. Furthermore, shielding the light-guiding key 20 by the cover 60 can reduce the probability of accidental touches on the light-guiding key 20. When the cover 60 is in the open position, the user can operate the light-guiding key 20.

[0090] Specifically, the cover 60 and the housing 10 may form a rotating portion. Figure 10 As shown, when the cover 60 is in the open position, the end of the cover 60 away from the rotating portion is separated from the housing 10. Figure 11 As shown, when the cover 60 is in the closed position, the end of the cover 60 away from the rotating portion is in contact with the housing 10 .

[0091] The rotational connection can be a hinge, bearing, rotating shaft, or other mechanical connection method. For example, the housing 10 can be provided with a groove. The cover 60 can be provided with a protrusion that matches the groove. The groove and protrusion rotate together to form a hinge, thereby achieving a rotational connection between the cover 60 and the housing 10. For another example, the housing 10 and the cover 60 can each be provided with corresponding mounting holes. A rotating shaft can be inserted into the mounting hole. The rotational connection between the housing 10 and the cover 60 can be achieved via the rotating shaft.
