[0002] In related technologies, headphones, such as bone conduction headphones, include a mounting box assembly, which can be at least one of a transducer assembly, a control box assembly, and a battery box assembly. The mounting box assembly has an indicator light on it, which reflects information such as the headphone's battery level or volume. However, currently, the waterproof performance of mounting box assemblies is poor, and external liquids can easily seep into the mounting box, damaging internal components (such as the indicator light or the circuit board electrically connected to the indicator light) and affecting the normal operation of the headphones. For example, when the headphones are in a deep underwater environment, external liquids can easily seep into the mounting box under water pressure. Therefore, improving the waterproof performance of the mounting box assembly has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0039] Please see Figure 1The headphone system 3000 provided in this application includes a charging case 2000 and headphones 1000. Specifically, the charging case 2000 is a structure in the headphone system 3000 used to charge the headphones 1000. Further, in some embodiments, the charging case 2000 includes a rechargeable battery and a charging circuit. When the headphones 1000 are placed in the charging case 2000, the charging circuit can transfer electrical energy from the rechargeable battery to the headphones 1000 to charge the headphones 1000.

[0040] Since the headphone system 3000 in this embodiment includes the headphone 1000, it is understood that the headphone system 3000 includes at least the same beneficial effects as the headphone 1000. Therefore, for the beneficial effects of the headphone system 3000, please refer to the beneficial effects of the headphone 1000 described below.

[0041] Please see Figure 1 and Figure 2 The earphone 1000 provided in this application includes a mounting box assembly 100. The earphone 1000 can be worn on a user's ear and can be used in conjunction with devices such as mobile phones, computers, smart wearable devices (such as smartwatches, smart bracelets, smart glasses, smart helmets, etc.), head-mounted displays, and virtual reality devices. Specifically, in some embodiments, the earphone 1000 includes air-conduction earphones and bone-conduction earphones. Air-conduction earphones, i.e., air-conduction headphones, are earphones 1000 that transmit sound through air vibrations. Bone-conduction earphones, i.e., bone-conduction headphones, are earphones 1000 that convert sound into different mechanical vibrations and transmit sound waves through the skull, bony labyrinth, inner ear lymph, cochlea, auditory center, etc.

[0042] It should be noted that the user's ear can include the external auditory canal, concha, cymba conchae, triangular fossa, helix, and antitragus. Among these, the concha, cymba conchae, and triangular fossa have a certain depth and volume in three-dimensional space. The external auditory canal is a curved tube extending medially from the external auditory meatus deep within the concha to the tympanic membrane.

[0043] Furthermore, in some embodiments, the earphone 1000 includes a transducer assembly (including the first transducer assembly 230 and the second transducer assembly 330 described below), which is a structure in the earphone 1000 for enabling the user to hear sound. In one example, when the earphone 1000 is a bone conduction earphone, the transducer assembly is configured to be located in front of the ear when the earphone 1000 is worn, in which case the transducer assembly does not obstruct the external auditory canal. In another example, when the earphone 1000 is an air conduction earphone, the transducer assembly is configured to at least partially extend into at least one part of the concha, cymba conchae, and triangular fossa when the earphone 1000 is worn.

[0044] Furthermore, in some embodiments, when the earphone 1000 is a bone conduction earphone, the earphone 1000 includes a first ear hook assembly 200, a second ear hook assembly 300, and a rear hook assembly 400 disposed between the first ear hook assembly 200 and the second ear hook assembly 300, with the first ear hook assembly 200 and the second ear hook assembly 300 respectively hooked onto the left and right ears. The first ear hook assembly 200 includes a control box assembly 210, a first transducer assembly 230, and a first ear hook 250 located between the control box assembly 210 and the first transducer assembly 230. The second ear hook assembly 300 includes a battery box assembly 310, a second transducer assembly 330, and a second ear hook 350 located between the battery box assembly 310 and the second transducer assembly 330. Both the first transducer assembly 230 and the second transducer assembly 330 are used to convert electrical signals into mechanical vibrations so that the user can hear sound.

[0045] Specifically, when the earphone 1000 is in the wearing state, the back hook assembly 400 is wrapped around the back of the user's head, the first ear hook 250 and the second ear hook 350 are curved and hooked on the user's left and right ears, at least a portion of the first ear hook 250 and the second ear hook 350 are located on the back of the ear, the first transducer assembly 230 and the second transducer assembly 330 are located on the front of the ear, and neither the first transducer assembly 230 nor the second transducer assembly 330 blocks the external auditory canal.

[0046] It should be noted that in some embodiments, when the earphone 1000 is a bone conduction earphone, the mounting box assembly 100 may be at least one of the control box assembly 210, the battery box assembly 310, the first transducer assembly 230, and the second transducer assembly 330. Since the earphone 1000 in this embodiment includes the mounting box assembly 100, it is understood that the earphone 1000 includes at least the same beneficial effects as the mounting box assembly 100. Therefore, for the beneficial effects of the earphone 1000, please refer to the beneficial effects of the mounting box assembly 100 described below.

[0047] Please see Figures 2 to 4 The mounting box assembly 100 provided in this application includes a mounting box 10, a light-emitting element 20, a light guide element 30, and a connector 40. The mounting box 10 has a receiving cavity 11 and a through hole 13 communicating with the receiving cavity 11. The light-emitting element 20 is disposed in the receiving cavity 11 and is used to emit light. The light guide element 30 is disposed in the receiving cavity 11, and a portion of the light guide element 30 passes through the through hole 13. The light guide element 30 is used to guide the light emitted by the light-emitting element 20 out of the mounting box 10. The light guide element 30 includes a top surface 301 and a bottom surface 303 facing away from each other, and a peripheral side surface 305 located between the top surface 301 and the bottom surface 303. The connector 40 connects the bottom surface 303 to the inner wall of the mounting box 10 and connects the peripheral side surface 305 to the inner wall of the mounting box 10. The connector 40 is used to block the communication between the receiving cavity 11 and the through hole 13.

[0048] The mounting box 10 is a structure in the mounting box assembly 100 that can house and protect devices such as the light-emitting element 20, the light guide element 30, and the connector 40. The mounting box 10 is made of materials including, but not limited to, plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. For example, the mounting box 10 is made of plastic, which makes it lighter, thus contributing to the portability of both the mounting box assembly 100 and the earphone 1000. For example, in the mounting box assembly 100, which is a battery box assembly 310 (… Figure 1 In the case shown), the mounting box 10 is a battery box in the battery box assembly 310 used to house the battery.

[0049] Please combine Figure 2 In some embodiments, the mounting box 10 includes a box body 101 and a cover 103, which are connected to form a receiving cavity 11. Specifically, the connection between the box body 101 and the cover 103 can be detachable or non-detachable. Detachable connections include, but are not limited to, screw connections, snap-fit ​​connections, or a combination of screw connections and snap-fit ​​connections. Non-detachable connections include, but are not limited to, adhesive connections, welding, or a combination of adhesive connections and welding connections.

[0050] The light-emitting element 20 is a structure in the mounting box assembly 100 used for emitting light. Specifically, the light-emitting element 20 can reflect the light emitted by the earphone 1000. Figure 1 The light source 20 may display information such as battery level or volume (as shown). In some embodiments of this application, the light-emitting element 20 includes at least one, which is disposed in the receiving cavity 11 and is capable of emitting light. The light-emitting element 20 may be an LED lamp bead, etc.

[0051] In some embodiments, the mounting box assembly 100 may further include a circuit board 50 disposed in the receiving cavity 11. The light-emitting element 20 is electrically connected to the circuit board 50, so that the circuit board 50 can deliver electrical energy to the light-emitting element 20 to cause the light-emitting element 20 to emit light. Furthermore, the circuit board 50 can also control the brightness, color, and emission frequency of the light-emitting element 20.

[0052] The light guide 30 is a structure in the mounting box assembly 100 used to guide the propagation of light. In some embodiments of this application, the top surface 301 is opposite to the light-emitting element 20, so that the top surface 301 can receive the light emitted by the light-emitting element 20, and the bottom surface 303 can guide the light to the through hole 13 so that the light can be observed by the user. The light guide 30 increases the number of refractions of light, thereby promoting uniform light guiding, that is, making the light more uniform and softer, effectively avoiding phenomena such as scattering, light leakage, or crosstalk. It should be noted that in some embodiments, the material of the light guide 30 includes, but is not limited to, PC (polycarbonate) or PMMA (polymethyl methacrylate).

[0053] The connector 40 is a structure in the mounting box assembly 100 used to connect the light guide 30 and the mounting box 10, and to block the communication between the receiving cavity 11 and the through hole 13. In some embodiments of this application, the connector 40 is an adhesive. Thus, the adhesive can connect the light guide 30 and the mounting box 10, improving the ease of installation of the light guide 30; on the other hand, it can seal the gap between the bottom surface 303 and the inner wall of the mounting box 10, and the gap between the peripheral side surface 305 and the inner wall of the mounting box 10, thereby blocking the communication between the receiving cavity 11 and the through hole 13, preventing external liquid from entering the receiving cavity 11 through the through hole 13 and causing damage to the devices (such as the light-emitting element 20 and the circuit board 50) in the receiving cavity 11, and improving the stability and reliability of the mounting box assembly 100 and the earphone 1000.

[0054] In the mounting box assembly 100 of this application embodiment, the light guide 30 includes a top surface 301 and a bottom surface 303 facing away from each other, and a peripheral side surface 305 located between the top surface 301 and the bottom surface 303. The connector 40 connects the bottom surface 303 and the inner wall of the mounting box 10, and connects the peripheral side surface 305 and the inner wall of the mounting box 10. Thus, compared to the light guide 30 only having a connector 40 between it and the inner wall of the through hole 13, the contact area between the connector 40 and the light guide 30 is larger, which helps to improve the waterproof performance between the light guide 30 and the mounting box 10, and reduces the possibility of external liquid entering the accommodating cavity 11 through the through hole 13. That is, when the earphone 1000 is in a deep underwater environment, it is difficult for external liquid to flow into the interior of the mounting box 10 under water pressure, thereby preventing the devices in the accommodating cavity 11 from being damaged by external liquid, and improving the stability and reliability of the mounting box assembly 100 and the earphone 1000.

[0055] The mounting box assembly 100 will be further explained below with reference to the accompanying drawings.

[0056] Please see Figure 3 and Figure 5In some embodiments, the light guide 30 includes a body 31 and a first light guide post 33. The body 31 includes a first side 311 and a second side 313 facing away from each other, with the first side 311 of the body 31 opposite to the inner wall of the mounting box 10. The first light guide post 33 protrudes from the first side 311 of the body 31 in a direction away from the second side 313 of the body 31, and the first light guide post 33 passes through the through hole 13. The arrangement of the first light guide post 33 ensures that the light guide 30 can guide the light emitted by the light-emitting element 20 to the outside of the mounting box 10.

[0057] Specifically, in some embodiments, the bottom surface 303 of the light guide 30 may include the first side 311 of the body 31, and the top surface 301 of the light guide 30 may include the second side 313 of the body 31. The connector 40 connects the bottom surface 303 and the inner wall of the mounting box 10 as follows: the connector 40 is disposed between the first side 311 of the body 31 and the inner wall of the mounting box 10, and is connected to both the first side 311 of the body 31 and the inner wall of the mounting box 10. Thus, the connector 40 can seal the gap between the first side 311 of the body 31 and the inner wall of the mounting box 10, preventing external liquid from entering the receiving cavity 11 through the gap between the first side 311 of the body 31 and the inner wall of the mounting box 10. Wherein, when the first light guide post 33 passes through the through hole 13, the first light guide post 33 is press-fitted with the inner wall of the through hole 13, which further prevents external liquid from flowing into the receiving cavity 11 through the through hole 13.

[0058] Furthermore, please combine Figure 4 In some embodiments, the cross-section of the first light guide post 33 gradually decreases in the direction from the second side 313 to the first side 311 of the body 31. It is understood that the cross-sectional size of the through hole 13 also gradually decreases in the direction from the second side 313 to the first side 311 of the body 31. Therefore, compared to a situation where the cross-section of the first light guide post 33 is the same in the direction from the second side 313 to the first side 311 of the body 31, on the one hand, the inner wall of the through hole 13 can guide the installation of the first light guide post 33, thereby improving the assembly efficiency of the light guide 30; on the other hand, the gap between the first light guide post 33 and the through hole 13 is smaller, thereby improving the waterproof performance between the light guide 30 and the mounting box 10.

[0059] In some embodiments, the light guide 30 further includes a second light guide post 35, which protrudes from the second side 313 of the body 31 toward the first side 311 away from the body 31, and the second light guide post 35 corresponds to and cooperates with the light-emitting element 20.

[0060] Specifically, in some embodiments, the second light guide post 35 can receive the light emitted by the light-emitting element 20, thus allowing the light to be transmitted within the body 31 and guided to the through hole 13 via the first light guide post 33, so that the light can be observed by the user. The second light guide post 35 increases the number of refractions of the light, thereby promoting uniform light guiding; that is, it makes the light more uniform and softer, effectively avoiding phenomena such as scattering, light leakage, or crosstalk. Furthermore, during the installation of the light guide element 30, the second light guide post 35 also facilitates the user's grip on the light guide element 30, thereby facilitating its assembly and improving the assembly efficiency of the mounting box assembly 100.

[0061] In some embodiments, the second light guide post 35 includes one, and the quantity relationship between the second light guide post 35 and the light-emitting element 20 is one-to-one or one-to-many, that is, one second light guide post 35 corresponds to one light-emitting element 20, or one second light guide post 35 corresponds to multiple light-emitting elements 20. In other embodiments, the second light guide post 35 includes at least two, and the second light guide posts 35 are spaced apart on the second side 313 of the body 31.

[0062] Please see Figure 3 and Figure 5 In some embodiments, the first light guide post 33 and the second light guide post 35 are staggered in the first direction, which is perpendicular to the direction from the first side 311 to the second side 313 of the body 31. This prevents the light-emitting element 20 from directly corresponding to the through hole 13, which would cause the light emitted by the light-emitting element 20 to directly pass through the through hole 13 and affect the uniformity of light emission.

[0063] Please see Figure 3 and Figure 4 In some embodiments, the inner wall of the mounting box 10 is provided with a receiving groove 15, the through hole 13 passes through the bottom wall of the receiving groove 15, at least a portion of the light guide 30 is accommodated in the receiving groove 15, and the connector 40 is disposed between the light guide 30 and the bottom wall of the receiving groove 15, and between the light guide 30 and the side wall of the receiving groove 15.

[0064] Specifically, in some embodiments, the inner wall of the mounting box 10 is provided with a groove, which is recessed from the inner wall of the mounting box 10 toward the center away from the receiving cavity 11, and the receiving groove 15 is a groove. In other embodiments, the inner wall of the mounting box 10 is provided with a protrusion, which protrudes from the inner wall of the mounting box 10 toward the center of the receiving cavity 11, and the protrusion is provided with a groove, and the receiving groove 15 is a groove.

[0065] The receiving groove 15 facilitates the installation and positioning of the light guide 30, thereby improving the assembly efficiency of the mounting box assembly 100. Furthermore, when the connector 40 is made of adhesive, the receiving groove 15 also restricts the flow of the adhesive, preventing irregular flow from damaging the internal structure of the receiving cavity 11, thus ensuring the integrity of the mounting box assembly 100 and the earphone 1000. Figure 1 (As shown) is working normally.

[0066] In some embodiments, when the connector 40 is made of adhesive, the assembly steps of the connector 40 and the light guide 30 can be as follows: First, the connector 40 is placed in the receiving groove 15; then, the first light guide post 33 is aligned with the through hole 13, and force is applied to the light guide 30 until the first light guide post 33 extends into the through hole 13, thus completing the assembly of the connector 40 and the light guide 30. During the process of the first light guide post 33 extending into the through hole 13, the connector 40 is compressed by the light guide 30, causing a portion of the connector 40 to be compressed from the bottom surface 303 to the peripheral surface 305, thereby enabling the connector 40 to connect the bottom surface 303 and the inner wall of the mounting box 10, and to connect the peripheral surface 305 and the inner wall of the mounting box 10. It is understood that the assembly steps of the connector 40 and the light guide 30 in the above embodiments are merely illustrative examples. In other embodiments, the assembly steps of the connector 40 and the light guide 30 can also take other forms, which will not be described in detail here.

[0067] Please continue reading. Figure 3 and Figure 4 In some embodiments, a boss 17 is provided on the bottom wall of the receiving groove 15. The boss 17 protrudes from the bottom wall of the receiving groove 15 toward the center of the receiving cavity 11 and surrounds the through hole 13. The light guide 30 abuts against the boss 17, and the connector 40 surrounds the boss 17.

[0068] Specifically, please combine Figure 5 In some embodiments, a boss 17 is provided on the bottom wall of the receiving groove 15. When the light guide 30 is connected to the mounting box 10, the first side 311 of the body 31 abuts against the boss 17. When the connector 40 is adhesive, the boss 17 prevents adhesive from flowing out of the mounting box 10 through the through hole 13 when it is poured into the receiving groove 15, thereby preventing irregular flow of adhesive from damaging the internal structure of the receiving cavity 11, and thus ensuring the integrity of the mounting box assembly 100 and the earphone 1000. Figure 1 (As shown) is working normally.

[0069] In some embodiments, the depth of the receiving groove 15 is greater than the height of the body 31. Therefore, the body 31 can be completely housed within the receiving groove 15. Compared to a situation where the depth of the receiving groove 15 is less than the height of the body 31, on the one hand, the sealing area formed between the peripheral side surface 305 of the light guide 30 and the inner wall of the receiving groove 15 is larger, thereby improving the waterproof performance between the light guide 30 and the mounting box 10; on the other hand, it reduces the possibility of adhesive overflowing from the receiving groove 15 when the connector 40 is made of adhesive, thereby preventing damage to the internal structure of the receiving cavity 11, and ensuring the normal operation of the mounting box assembly 100 and the earphone 1000.

[0070] Furthermore, when the depth of the receiving groove 15 is greater than the height of the main body 31, and the connector 40 connects the bottom surface 303 and the inner wall of the mounting box 10, and connects the peripheral side surface 305 and the inner wall of the mounting box 10, that is, when the connector 40 connects the first side 311 of the main body 31 and the bottom wall of the receiving groove 15, and connects the side surface of the main body 31 (located between the first side 311 and the second side 313 of the main body 31) and the side wall of the receiving groove 15, the user can add the connector 40 (adhesive) to the receiving groove 15 again, so that the second side 313 of the main body 31 is covered with the connector 40, thereby further improving the waterproof performance between the light guide 30 and the mounting box 10.

[0071] In other embodiments, the depth of the receiving groove 15 is greater than the height of the body 31 and the second light guide post 35. Therefore, the body 31 and the second light guide post 35 can be completely housed within the receiving groove 15. Compared to a situation where the depth of the receiving groove 15 is less than the height of the body 31 and the second light guide post 35, on the one hand, the sealing area formed between the peripheral side surface 305 of the light guide 30 and the inner wall of the receiving groove 15 is larger, thereby improving the waterproof performance between the light guide 30 and the mounting box 10; on the other hand, it reduces the possibility of adhesive overflowing from the receiving groove 15 when the connector 40 is made of adhesive, thereby preventing damage to the internal structure of the receiving cavity 11, and ensuring the normal operation of the mounting box assembly 100 and the earphone 1000.

[0072] In addition, when the depth of the receiving groove 15 is greater than the height of the main body 31 and the second light guide post 35, and the connector 40 connects the bottom surface 303 and the inner wall of the mounting box 10, and connects the peripheral side surface 305 and the inner wall of the mounting box 10, the user can add the connector 40 (adhesive) to the receiving groove 15 again, so that the top surface 301 of the light guide 30 is covered with the connector 40, thereby further improving the waterproof performance between the light guide 30 and the mounting box 10.

[0073] Please see Figure 3 , Figure 5 and Figure 6In some embodiments, the mounting box 10 further includes a reinforcing member 19 disposed between the inner wall of the receiving groove 15 and the light guide 30, so that the inner wall of the receiving groove 15 and the light guide 30 are interference-fitted. This results in greater stability of the light guide 30 within the receiving groove 15, thereby preventing the earphone 1000 ( Figure 1 As shown, during use, the light guide 30 falls out of the receiving groove 15, thereby ensuring the normal operation of the mounting box assembly 100 and the earphone 1000.

[0074] Specifically, in some embodiments, the sidewall of the receiving groove 15 is provided with a rib, which protrudes from the sidewall of the receiving groove 15 toward the center of the receiving groove 15, and the rib forms a reinforcing member 19. In other embodiments, the peripheral side surface 305 of the light guide 30 (such as the side surface of the body 31) is provided with a rib, which protrudes from the peripheral side surface 305 of the light guide 30 and extends in a direction away from the center of the light guide 30, and the rib forms a reinforcing member 19.

[0075] In some embodiments, the reinforcing member 19 comprises one. For example, one reinforcing member 19 is disposed on the sidewall of the receiving groove 15. Another example is that one reinforcing member 19 is disposed on the peripheral side surface 305 of the light guide 30. In other embodiments, the reinforcing member 19 comprises at least two, and the at least two reinforcing members 19 are spaced apart. For example, at least two reinforcing members 19 are spaced apart on the sidewall of the receiving groove 15. Another example is that at least two reinforcing members 19 are spaced apart on the peripheral side surface 305 of the light guide 30.

[0076] More specifically, in some embodiments, the cross-section of the reinforcing member 19 is triangular, with the free end of the triangle being a pointed tip. When the light guide 30 is disposed in the receiving groove 15, the reinforcing member 19 is located between the side wall of the receiving groove 15 and the light guide 30, and the reinforcing member 19 is capable of elastic deformation. This achieves an interference fit between the side wall of the receiving groove 15 and the light guide 30, improving the stability of the light guide 30 installation; it also prevents the pointed tip of the reinforcing member 19 from rigidly colliding with the light guide 30, causing damage to the light guide 30, or from rigidly colliding with the inner wall of the receiving groove 15, causing damage to the mounting box 10, thereby ensuring the stability and reliability of the mounting box assembly 100 operation.

[0077] It should be noted that, in some embodiments, the material of the reinforcing member 19 may include, but is not limited to, rubber and silicone. It is understood that, in other embodiments, the cross-section of the reinforcing member 19 may also be a racetrack shape, a square shape, a semi-circle shape, or an irregular shape, and no limitation is made here.

[0078] Please see Figure 3 and Figure 6In some embodiments, the inner wall of the mounting box 10 includes a first sub-wall 105 and a second sub-wall 107 that are in contact with each other, and the light guide 30 is disposed on the first sub-wall 105. The thickness of the first sub-wall 105 is greater than the thickness of the second sub-wall 107.

[0079] Specifically, in some embodiments, the first sub-wall 105 may include the bottom wall of the receiving groove 15, and the second sub-wall 107 may include the portion of the inner wall of the mounting box 10 excluding the bottom wall of the receiving groove 15. The thickness of the first sub-wall 105 is greater than the thickness of the second sub-wall 107, thereby improving the light-shielding effect of the first sub-wall 105 and preventing light from leaking out of the mounting box 10 through positions on the first sub-wall 105 other than the through hole 13, thus contributing to the uniformity of light emission.
