[0031] Headphones typically include microphones. Headphones with built-in microphones are not only suitable for calls but also for recording, voice recognition, and other scenarios, meeting diverse user needs. With the development of headphones, swimming headphones have emerged on the market. Swimming headphones are usually used underwater, therefore requiring a high level of waterproofing. Currently, microphones in ordinary headphones only have basic waterproofing functions, such as splash resistance or sweat resistance, but cannot meet the waterproofing requirements for swimming. When users wear headphones while swimming or diving, the microphone is easily damaged by water ingress. To address this issue, this application provides a transducer structure 100 (shown in Figure 2), a headphone 1000 (shown in Figure 1), and a headphone system 10000 (shown in Figure 5).

[0032] Please refer to Figures 1 and 2. The bone conduction headphones 1000 of this application embodiment include a transducer structure 100. The bone conduction headphones 1000 use the human skeleton as a medium, converting sound into mechanical vibrations. These mechanical vibrations transmit sound waves through the human skeleton, enabling the user to hear. Since the sound from the bone conduction headphones 1000 acts on the bones, long-term use will not significantly affect the user's eardrum, effectively protecting the user's hearing. The bone conduction headphones 1000 of this application can be used as swimming headphones, allowing users to wear them while swimming and diving. The bone conduction headphones 1000 have good waterproof performance.

[0033] The transducer structure 100 of this application is designed to fit snugly against human skin. When the headphones are in use, the transducer structure 100 vibrates, and this vibration is conducted through the bones of the body, allowing the user to hear sound. The headphones of this application also include a functional box assembly 300, which is electrically connected to the transducer structure 100. The functional box assembly 300 may include a battery box assembly 303 and / or a control box assembly 301. The control box assembly 301 can be used to control the headphones' power on / off and adjust the volume. The battery box assembly 303 includes a battery that powers other components of the headphones to enable them to function properly.

[0034] Referring to Figure 1, in some embodiments, the headphones also include ear hooks 500 and back hooks 700. Ear hooks 500 are used for electrical connection between the battery box assembly 303 and the transducer structure 100, and for electrical connection between the control box assembly 301 and the transducer structure 100. Back hooks 700 are used for electrical connection between the battery box assembly 303 and the control box assembly 301. When a user wears the headphones, the back hooks 700 are worn on the head, and the ear hooks 500 are worn behind the ears, thereby improving the stability of the headphones and preventing them from easily falling off when the user is outdoors or exercising.

[0035] Please refer to Figures 3 and 4. The transducer structure 100 of the bone conduction headphone 1000 according to this embodiment includes a transducer box 30, a microphone 50, and a waterproof component 10. The transducer box 30 has a receiving cavity 31 and a pickup hole 33 penetrating through the side wall of the transducer box 30, and the receiving cavity 31 communicates with the pickup hole 33. The microphone 50 is installed in the receiving cavity 31 and corresponds to the pickup hole 33. The waterproof component 10 is installed in the receiving cavity 31 and covers the opening of the pickup hole 33 facing the inside of the transducer box 30. The microphone 50 corresponds to the waterproof component 10, and the waterproof component 10 includes a waterproof and breathable membrane 11, which covers the pickup hole 33.

[0036] Specifically, the transducer box 30 is used to install the microphone 50, the waterproof component 10, and other components of the transducer structure 100. The pickup hole 33 is used to pick up sound information and transmit it to the microphone 50 for processing. The pickup hole 33 can be located on the side of the transducer box 30 closer to the human body or on the side of the transducer box 30 away from the human body. Preferably, to ensure the sound pickup effect of the microphone 50, the pickup hole 33 can be located on the side of the transducer structure 100 away from the human body. The shape of the pickup hole 33 can be, but is not limited to, ellipse, circle, triangle, quadrilateral, or other polygons. Preferably, to facilitate the production and processing of the pickup hole 33, the shape of the pickup hole 33 can be circular or ellipse. The pickup hole 33 in this embodiment is elliptical. The number of pickup holes 33 can be one, two, three, four or more, and the number of microphones 50 can also be one, two, three, four or more. The number of pickup holes 33 can be the same as the number of microphones 50, and the positions of the pickup holes 33 can correspond one-to-one with the positions of the microphones 50.

[0037] Referring to Figures 3 and 4, microphone 50 is used to pick up the user's voice. When the user speaks, their voice enters the receiving cavity 31 through the pickup hole 33 and is picked up by microphone 50. For example, microphone 50 is used to capture the user's voice during a voice call to ensure that the other party in the call can hear the user clearly. Microphone 50 can also be used to capture the user's voice commands, thereby enabling device control. For example, microphone 50 can control the headphones to play music, adjust the volume, and answer phone calls by capturing the user's voice commands.

[0038] The waterproof component 10 is installed on the inner wall of the transducer box 30 and located between the microphone 50 and the pickup hole 33. The waterproof component 10 prevents external liquid entering the pickup hole 33 from flowing into the microphone 50, thus avoiding damage to the microphone 50. On the other hand, the waterproof component 10 also allows the user's voice to pass through; sound entering the pickup hole 33 can pass through the waterproof component 10 and enter the microphone 50 for pickup. The waterproof component 10 of this application improves the waterproof performance of the transducer structure 100 without affecting the microphone 50's ability to pick up the user's voice. The bone conduction headphones 1000 have good waterproof performance and a long service life.

[0039] Please refer to Figures 3 and 4. When the waterproof component 10 is installed on the inner wall of the transducer box 30, the waterproof and breathable membrane 11 corresponds to both the pickup hole 33 and the microphone 50. The waterproof and breathable membrane 11 effectively blocks the flow of external liquid entering the pickup hole 33 towards the microphone 50, preventing water damage to the microphone 50. Furthermore, the waterproof and breathable membrane 11 allows the user's voice to pass through it and enter the microphone 50 for pickup. The waterproof and breathable membrane 11 has good waterproof performance, preventing liquid from easily entering the microphone 50 during use, thus reducing the risk of damage to the microphone 50 and extending the lifespan of the bone conduction headphones 1000. The waterproof and breathable membrane 11 can have one, two, three, or more layers; in this application, it has only one layer, resulting in a relatively simple structure for the waterproof component 10. The waterproof and breathable membrane 11 can be made of polytetrafluoroethylene (PTFE), expanded polytetrafluoroethylene (ePTFE), polyurethane resin, or thermoplastic polyurethane, etc.

[0040] Please refer to Figures 3 and 4. The microphone 50 is equipped with a microphone channel 55. The user's voice can enter the microphone channel 55 through the pickup hole 33 and the waterproof and breathable membrane 11, thus the sound can be picked up by the microphone 50. If external liquid enters the microphone channel 55, the microphone 50 is easily damaged. The pickup hole 33 and the microphone channel 55 are misaligned in the axial direction, that is, the central axis of the pickup hole 33 and the central axis of the microphone channel 55 do not coincide. When the user is swimming or diving, the water flowing towards the microphone 50 usually enters the pickup hole 33 first and then flows into the microphone 50. With the pickup hole 33 and the microphone channel 55 misaligned in the axial direction of the pickup hole 33, liquid entering the pickup cavity is less likely to flow into the microphone channel 55, thereby improving the waterproof performance of the transducer structure 100 and reducing the likelihood of microphone 50 failure.

[0041] When the headphones are swimming headphones, external liquids can easily enter the microphone 50 through the pickup hole 33 while the user is swimming or diving, potentially damaging the microphone 50. Current swimming headphones typically use a steel mesh waterproof mesh between the pickup hole 33 and the microphone 50 to prevent external liquids from entering the microphone 50. However, this type of waterproof mesh has a low waterproof protection level and poor waterproofing effect, failing to effectively protect the microphone 50. This application provides a waterproof and breathable membrane 11 between the pickup hole 33 and the microphone 50. This membrane effectively prevents external liquids from entering the microphone 50, resulting in better waterproofing of the transducer structure 100, reducing the risk of microphone damage, and extending the service life of the bone conduction headphones 1000.

[0042] In the transducer structure 100 of this application embodiment, the waterproof component 10 is located between the pickup hole 33 and the microphone 50. The waterproof component 10 includes a waterproof and breathable membrane 11, which can effectively prevent liquid entering the pickup hole 33 from flowing to the microphone 50. When the user wears the bone conduction headphones 1000 while swimming or diving, external liquid is less likely to enter the microphone 50, and the microphone 50 is less likely to fail or be damaged. The bone conduction headphones 1000 have a high waterproof rating and good waterproof performance, and are less prone to damage.

[0043] Please refer to Figures 3 and 4. The waterproof assembly 10 of the microphone 50 of the bone conduction headphone 1000 according to this embodiment of the application further includes a first water-collecting double-sided adhesive layer 13 and a second water-collecting double-sided adhesive layer 15. The first water-collecting double-sided adhesive layer 13 and the second water-collecting double-sided adhesive layer 15 are respectively disposed on opposite sides of the waterproof and breathable membrane 11. The side of the first water-collecting double-sided adhesive layer 13 facing away from the waterproof and breathable membrane 11 is connected to the transducer box 30.

[0044] The first water-absorbing double-sided adhesive layer 13 is bonded to the side of the waterproof and breathable membrane 11 facing the inner wall of the transducer box 30. Both sides of the first water-absorbing double-sided adhesive layer 13 are adhesive. When the waterproof component 10 is installed on the inner wall of the transducer box 30, the side of the first water-absorbing double-sided adhesive layer 13 facing away from the waterproof and breathable membrane 11 is bonded to the inner wall of the transducer box 30. The first water-absorbing double-sided adhesive layer 13 is used to fix the relative position of the waterproof and breathable membrane 11 and the transducer box 30. That is, the first water-absorbing double-sided adhesive layer 13 enables the waterproof component 10 to be firmly connected to the inner wall of the transducer box 30, and the waterproof component 10 is not easily displaced or detached relative to the transducer box 30. Furthermore, because the connection between the first water-absorbing double-sided adhesive layer 13 and the inner wall of the transducer box 30 is relatively tight, liquid in the pickup hole 33 can be prevented from entering the receiving cavity 31 through the gap between the first water-absorbing double-sided adhesive layer 13 and the inner wall of the transducer box 30.

[0045] The second water-absorbing double-sided adhesive layer 15 is bonded to the side of the waterproof and breathable membrane 11 facing away from the inner wall of the transducer box 30. Both sides of the second water-absorbing double-sided adhesive layer 15 are adhesive. When the waterproof component 10 is installed on the inner wall of the transducer box 30, the side of the second water-absorbing double-sided adhesive layer 15 facing away from the waterproof and breathable membrane 11 can be bonded to the support member 70 of the transducer structure 100. The microphone 50 is installed on the support member 70 of the transducer structure 100. Thus, the waterproof component 10 can maintain a fixed connection with the microphone 50.

[0046] Both the first and second water-absorbing double-sided adhesive layers 13 and 15 maintain good adhesion in water. Therefore, even if liquid from the pickup hole 33 enters the first and / or second water-absorbing double-sided adhesive layers 13 and 15, the waterproof component 10 remains fixedly connected to the inner wall of the transducer box 30 and the microphone 50. This effectively prevents liquid from entering the microphone 50, resulting in good waterproofing of the transducer structure 100. When the waterproof component 10 is bonded to the inner wall of the transducer box 30 and the support member 70 of the transducer structure 100, no complex connection structure is required on the transducer box 30 and the support member 70. The overall structure of the transducer structure 100 is relatively simple and easy to manufacture.

[0047] Please refer to Figures 3 and 4. Further, in some embodiments, the waterproof component 10 also includes a polyethylene terephthalate (PET) layer and a third water-collecting double-sided adhesive layer. The second water-collecting double-sided adhesive layer is bonded to one side of the PET layer on the side opposite to the first water-collecting double-sided adhesive layer 13, and the third water-collecting double-sided adhesive layer is bonded to the other side of the PET layer.

[0048] At this time, the PET layer is disposed between the second water-absorbing double-sided adhesive layer 15 and the third water-absorbing double-sided adhesive layer. One side of the third water-absorbing double-sided adhesive layer is bonded to the PET, and the other side of the third water-absorbing double-sided adhesive layer is bonded to the support member 70 of the transducer structure 100, so that the waterproof component 10 can maintain a fixed connection with the microphone 50.

[0049] Because the waterproof and breathable membrane 11 is generally thin, the transducer structure 100 will be subjected to a certain water pressure when the user wears the headphones while swimming or diving. The water flow entering the pickup hole 33 will exert pressure on the waterproof and breathable membrane 11, making it prone to damage. When a PET layer is provided on the side of the first water-accumulating double-sided adhesive layer 13 facing away from the inner side of the transducer box 30, the PET layer can support and fix the waterproof and breathable membrane 11. Therefore, even when the water flow squeezes the waterproof and breathable end, the waterproof and breathable membrane 11 is not easily damaged, thus effectively preventing liquid in the pickup hole 33 from flowing towards the microphone 50. When the waterproof component 10 includes a PET layer, the bone conduction headphones 1000 can be used in diving environments at a certain depth, the waterproof and breathable membrane 11 is not easily damaged, the microphone 50 is not easily damaged by water ingress, and the user experience is better.

[0050] Please refer to Figures 3 and 4. In some embodiments, the transducer structure 100 further includes a support member 70, which is installed in the accommodating cavity 31. The support member 70 includes a first side 71 and a second side 72 facing away from each other. The first side 71 of the support member 70 is opposite to the inner wall of the transducer box 30. The support member 70 is provided with a through hole 73 penetrating the first side 71 and the second side 72. The first water-collecting double-sided adhesive layer 13 has a first through hole 131, and the second water-collecting double-sided adhesive layer 15 has a second through hole 151. The three-layer water-absorbing double-sided adhesive has a third perforation, the PET layer has a fourth perforation, the first water-absorbing double-sided adhesive is bonded to the inner wall of the transducer box 30, the third water-absorbing double-sided adhesive is bonded to the first side 71 of the support member 70 on the side opposite to the PET layer, and the microphone 50 is installed on the second side 72 of the support member 70. The pickup hole 33, the first perforation 131, the waterproof and breathable membrane 11, the second perforation 151, the fourth perforation, the third perforation, the through hole 73 and the microphone 50 are sequentially corresponding in the axial direction of the pickup hole 33.

[0051] The support member 70 has a certain structural strength. When the third double-sided adhesive is bonded to the first side 71 of the support member 70 on the side opposite to the PET layer, the support member 70 can provide a certain load-bearing function for the waterproof component 10, and the waterproof component 10 is not easily damaged under the pressure of water flow. In this application, the support member 70 is a circuit board, the waterproof component 10 is bonded to the first side 71 of the circuit board, and the microphone 50 is installed on the second side 72 of the circuit board and electrically connected to the circuit board.

[0052] The pickup hole 33, the first through hole 131, the second through hole 151, the fourth through hole, the third through hole, and the via hole 73 are all used to enable the microphone 50 to pick up sound effectively. The via hole 73 is connected to the microphone channel 55. When the user speaks, the user's voice passes sequentially through the pickup hole 33, the first through hole 131, the waterproof and breathable membrane 11, the second through hole 151, the fourth through hole, the third through hole, and the via hole 73 into the microphone channel 55, so that the microphone 50 can pick up the sound.

[0053] In other embodiments, where the waterproof component 10 does not include the PET layer and the third water-absorbing double-sided adhesive layer, the microphone hole 33, the first perforation 131, the second perforation 151, and the through hole 73 are sequentially arranged along the axial direction of the microphone hole 33. When the user speaks, the user's voice passes through the microphone hole 33, the first perforation 131, the waterproof and breathable membrane 11, the second perforation 151, and the through hole 73, and enters the microphone channel 55, thereby allowing the microphone 50 to pick up the sound.

[0054] Referring to Figures 3 and 4, in some embodiments, the diameters of the first perforation 131, the second perforation 151, the third perforation, and the fourth perforation are all larger than the diameter of the pickup hole 33. This facilitates the installation of the waterproof component 10. When the waterproof component 10 is bonded to the inner wall of the transducer box 30, precise alignment between the waterproof component 10 and the pickup hole 33 is not required, making the installation of the waterproof component 10 simpler and more efficient.

[0055] Referring to Figures 3 and 4, in some embodiments, the inner wall of the transducer box 30 is provided with a positioning groove 39, which communicates with the pickup hole 33. The waterproof component 10 is installed in the positioning groove 39. The positioning groove 39 is formed by recessing from the inner wall of the transducer box 30 toward the outer wall of the transducer box 30, and is used for installing the waterproof component 10 therein. The positioning groove 39 can play a good positioning role for the waterproof component 10, which can effectively avoid the problem of the waterproof component 10 shifting during installation.

[0056] Please refer to Figures 3 and 4. In some embodiments, the microphone 50 includes a first microphone 51 and a second microphone 53, the waterproof assembly 10 includes a first waterproof assembly 101 and a second waterproof assembly 103, the sidewall of the transducer box 30 includes a bottom sidewall 35 and a peripheral sidewall 37, the pickup hole 33 includes a first pickup hole 331 disposed on the bottom sidewall 35 and a second pickup hole 333 disposed on the peripheral sidewall 37, the first microphone 51 is directly opposite the first waterproof assembly 101, the first waterproof assembly 101 includes a first waterproof and breathable membrane 11, the first waterproof and breathable membrane 11 covers the first pickup hole 331; the second microphone 53 is directly opposite the second waterproof assembly 103, the second waterproof assembly 103 includes a second waterproof and breathable membrane 11, the second waterproof and breathable membrane 11 covers the second pickup hole 333.

[0057] With microphone 50 including a first microphone 51 and a second microphone 53, microphone 50 has a better sound pickup effect for the user. A first waterproof and breathable membrane 11 prevents external liquid from flowing into the first microphone 51 from the first pickup hole 331, and a second waterproof and breathable membrane 11 prevents external liquid from flowing into the second microphone 53 from the second pickup hole 333. The transducer structure 100 has good waterproof performance, and both the first microphone 51 and the second microphone 53 are not easily damaged. In this application, the first microphone 51 and the second microphone 53 are far apart and at staggered angles, which effectively avoids interference between the two microphones 50, resulting in lower noise during sound pickup.

[0058] Referring to Figures 3 and 4, in some embodiments, the support member 70 includes a first support member 701 and a second support member 703. The first microphone 51 and the first waterproof component 101 are respectively mounted on opposite sides of the first support member 701, and the second microphone 53 and the second waterproof component 103 are respectively mounted on opposite sides of the second support member 703. In this application, both the first support member 701 and the second support member 703 are circuit boards. The first support member 701 provides support and electrical connection for the first microphone 51, and also supports the first waterproof component 101. The second support member 703 provides support and electrical connection for the second microphone 53, and also supports the second waterproof component 103. The first support member 701 and the second support member 703 can be connected by an electrical connector 705. For example, the electrical connector 705 can be a flexible circuit board. When the first support member 701 and the second support member 703 are connected by a flexible circuit board, it facilitates changes in the relative positions of the first support member 701 and the second support member 703.

[0059] Please refer to Figure 5. The headphone system 10000 of this application embodiment includes the bone conduction headphone 1000 of the above embodiment and a charging case 3000. The charging case 3000 is used to charge the bone conduction headphone 1000. The charging case 3000 is provided with a charging compartment. When the headphone needs to be charged, the headphone's battery case can be accommodated in the charging compartment, and the charging case 3000 can charge the battery inside the battery case.

[0060] In the headphone system 1000 of this application embodiment, the waterproof component 10 is located between the pickup hole 33 and the microphone 50. The waterproof component 10 includes a waterproof and breathable membrane 11, which can effectively prevent liquid entering the pickup hole 33 from flowing to the microphone 50. When the user wears the bone conduction headphones 1000 for swimming or diving, external liquid is less likely to enter the microphone 50, and the microphone 50 is less likely to fail or be damaged. The bone conduction headphones 1000 have a high waterproof rating and good waterproof performance, and are less prone to damage.
