[0030] Headphones usually have a microphone. Headphones with a built-in microphone are not only suitable for calls, but also can be used in various scenarios such as recording and voice recognition, meeting the diverse needs of users. With the development of headphones, swimming headphones have started to appear on the market. Swimming headphones usually need to be used underwater, so the waterproof level required for swimming headphones is usually relatively high. Currently, the microphones in ordinary headphones only have basic waterproof functions, for example, splash-proof or sweat-proof, etc., but cannot reach the waterproof level required for swimming scenarios. When users wear headphones to swim or dive, the microphone is easily damaged due to water ingress. To solve this problem, the embodiments of this application provide a transducer structure 100 ( Figure 2 as shown), a headphone 1000 ( Figure 1 as shown) and a headphone system 10000 ( Figure 5 as shown).

[0031] Please refer to Figure 1 and Figure 2, the bone conduction headphone 1000 of the embodiment of the present application includes a transducer structure 100. Among them, the bone conduction headphone 1000 uses the human bone as a medium. The bone conduction headphone 1000 converts sound into mechanical vibration, and this mechanical vibration transmits sound waves through the human bone so that the user can hear the sound. The sound of the bone conduction headphone 1000 acts on the bone, and long-term use will not cause great impact on the eardrum of the user's ear, and can effectively protect the user's hearing. The bone conduction headphone 1000 of the present application can be a swimming headphone, and the user can wear the bone conduction headphone 1000 to swim and dive, and the bone conduction headphone 1000 has good waterproof performance.

[0032] The transducer structure 100 of the present application is used to fit with the human skin. When the headphone is in use, the transducer structure 100 can generate vibration, and this vibration is conducted through the human bone, so that the user can hear the sound. The headphone of the present application further includes a function box assembly 300. The function box assembly 300 is electrically connected to the transducer structure 100. The function 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 power on and off of the headphone and adjust the volume of the headphone. The battery box assembly 303 includes a battery, and the battery is used to supply power to other components of the headphone so that the headphone can work normally.

[0033] Please refer to Figure 1 , in some embodiments, the headphone further includes an earhook 500 and a rear hook 700. The earhook 500 is used to electrically connect the battery box assembly 303 and the transducer structure 100, and is used to electrically connect the control box assembly 301 and the transducer structure 100. The rear hook 700 is used to electrically connect the battery box assembly 303 and the control box assembly 301. When the user wears the headphone, the rear hook 700 of the headphone is worn on the head, and the earhook 500 of the headphone is worn behind the ear, so as to improve the wearing stability of the headphone. When the user is outdoors or exercising, the headphone is not easy to fall off.

[0034] Please refer to Figure 3 and Figure 4 , the transducer structure 100 of the bone conduction headphone 1000 of the embodiment of the present application includes a transducer box 30, a microphone 50 and a waterproof component 10. The transducer box 30 is provided with a receiving cavity 31 and a sound pickup hole 33 penetrating through the side wall of the transducer box 30. The receiving cavity 31 is communicated with the sound pickup hole 33. The microphone 50 is installed in the receiving cavity 31 and corresponds to the sound pickup hole 33. The waterproof component 10 is installed in the receiving cavity 31 and covers the opening of the sound pickup hole 33 facing the inside of the transducer box 30. The microphone 50 corresponds to the waterproof component 10. The waterproof component 10 includes a waterproof breathable membrane 11, and the waterproof breathable membrane 11 covers the sound pickup hole 33.

[0035] 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 sound pickup hole 33 is used to pick up sound information and transmit the sound information to the microphone 50 for processing. The position of the sound pickup hole 33 can be opened on the side of the transducer box 30 close 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 sound pickup hole 33 can be opened on the side of the transducer structure 100 away from the human body. The shape of the sound pickup hole 33 can be, but is not limited to, oval, circular, triangular, quadrilateral, or other polygons, etc. Preferably, for the convenience of production and processing of the sound pickup hole 33, the shape of the sound pickup hole 33 can be circular or oval, etc. The sound pickup hole 33 in the embodiment of the present application is oval. The number of the sound pickup holes 33 can be one, two, three, four, or more, and the number of the microphones 50 can also be one, two, three, four, or more. The number of the sound pickup holes 33 can be the same as the number of the microphones 50, and the positions of the sound pickup holes 33 can correspond to the positions of the microphones 50 one by one.

[0036] Please refer to Figure 3 and Figure 4 , the microphone 50 is used to pick up the user's voice. When the user is speaking, the user's voice can enter the accommodation cavity 31 through the sound pickup hole 33 and be picked up by the microphone 50. Exemplarily, the microphone 50 is used to capture the user's voice during a voice call to ensure that the other party of the call can clearly hear the user's voice. The microphone 50 can also be used to capture the user's voice command, so as to control the device. For example, the microphone 50 can control the headphone to play music, adjust the volume, and answer the phone, etc. by capturing the user's voice command.

[0037] The waterproof component 10 is installed on the inner wall of the transducer box 30 and is located between the microphone 50 and the sound pickup hole 33. On the one hand, the waterproof component 10 can prevent the external liquid entering the sound pickup hole 33 from flowing towards the microphone 50 to avoid the external liquid flowing into the microphone 50 and causing damage to the microphone 50. On the other hand, the waterproof component 10 can also allow the user's voice to pass through, and the sound entering the sound pickup hole 33 can pass through the waterproof component 10 and enter the microphone 50 to be picked up by the microphone 50. The waterproof component 10 of the present application improves the waterproof performance of the transducer structure 100 while not affecting the microphone 50's pickup of the user's voice. The bone conduction headphone 1000 has better waterproof performance and a longer service life.

[0038] Please refer to Figure 3 and Figure 4, when the waterproof component 10 is installed on the inner wall of the transducer box 30, the waterproof breathable membrane 11 corresponds to both the sound pickup hole 33 and the microphone 50. The waterproof breathable membrane 11 can effectively block the flow of external liquid entering the sound pickup hole 33 towards the microphone 50, and it is not easy for the microphone 50 to get waterlogged and damaged. Moreover, the waterproof breathable membrane 11 allows the user's voice to pass through it and enter the microphone 50 to be picked up by the microphone 50. The waterproof breathable membrane 11 has good waterproof performance. When the bone conduction headset 1000 is in use, it is not easy for liquid to enter the microphone 50, the microphone 50 is not easily damaged, and the service life of the bone conduction headset 1000 is relatively long. The number of layers of the waterproof breathable membrane 11 can be one layer, two layers, three layers or more. In this application, the number of the waterproof breathable membranes 11 is one layer, and the structure of the waterproof component 10 is relatively simple. The material of the waterproof breathable membrane 11 can be polytetrafluoroethylene, expanded polytetrafluoroethylene, polyurethane resin, thermoplastic polyurethane, etc.

[0039] Please refer to Figure 3 and Figure 4 , the microphone 50 is provided with a microphone sound channel 55. The user's voice can enter the microphone sound channel 55 through the sound pickup hole 33 and the waterproof breathable membrane 11, so that the voice can be picked up by the microphone 50. When external liquid enters the microphone sound channel 55, the microphone 50 is likely to be damaged. Axially of the sound pickup hole 33, the sound pickup hole 33 and the microphone sound channel 55 can be arranged in a dislocation manner, that is, the central axis of the sound pickup hole 33 and the central axis of the microphone sound channel 55 do not coincide. When the user is swimming or diving, the water flow towards the microphone 50 usually first enters the sound pickup hole 33 and then flows into the microphone 50. When the sound pickup hole 33 and the microphone sound channel 55 are dislocated axially of the sound pickup hole 33, the liquid entering the sound pickup cavity is not easy to flow into the microphone sound channel 55, thereby improving the waterproof performance of the transducer structure 100, and it is not easy for the microphone 50 to have problems of failure.

[0040] When the headset is a swimming headset, when the user wears the headset to swim or dive, external liquid is likely to enter the microphone 50 from the sound pickup hole 33, and the microphone 50 is likely to be damaged. Currently, swimming headsets usually set a waterproof net woven with steel mesh between the sound pickup hole 33 and the microphone 50. The waterproof net is used to prevent external liquid from entering the microphone 50. However, the waterproof protection level of this type of waterproof net is relatively low, the waterproof effect is poor, and it cannot effectively protect the microphone 50 well. In this application, a waterproof breathable membrane 11 is provided between the sound pickup hole 33 and the microphone 50. The waterproof breathable membrane 11 can effectively prevent external liquid from entering the microphone 50. The transducer structure 100 has good waterproof performance, the microphone 50 is not easily damaged, and the service life of the bone conduction headset 1000 is relatively long.

[0041] In the transducer structure 100 of the embodiment of the present application, the waterproof component 10 is located between the sound pickup hole 33 and the microphone 50. The waterproof component 10 includes a waterproof breathable membrane 11, and the waterproof breathable membrane 11 can effectively prevent the liquid entering the sound pickup hole 33 from flowing towards the microphone 50. When the user wears the bone conduction headset 1000 to swim or dive, external liquid is not likely to enter the microphone 50, and the microphone 50 is not likely to fail and be damaged. The bone conduction headset 1000 has a high waterproof rating and good waterproof performance, and the bone conduction headset 1000 is not likely to be damaged.

[0042] Please refer to Figure 3 and Figure 4 , the microphone 50 waterproof component 10 of the bone conduction headset 1000 in the embodiment of the present application further includes a first water accumulation double-sided adhesive layer 13 and a second water accumulation double-sided adhesive layer 15. The first water accumulation double-sided adhesive layer 13 and the second water accumulation double-sided adhesive layer 15 are respectively arranged on the opposite sides of the waterproof breathable membrane 11, and the side of the first water accumulation double-sided adhesive layer 13 facing away from the waterproof breathable membrane 11 is connected to the transducer box 30.

[0043] Among them, the first water accumulation double-sided adhesive layer 13 is bonded to the side of the waterproof breathable membrane 11 facing the inner wall of the transducer box 30. Both sides of the first water accumulation double-sided adhesive layer 13 have adhesiveness. When the waterproof component 10 is installed on the inner wall of the transducer box 30, the side of the first water accumulation double-sided adhesive layer 13 facing away from the waterproof breathable membrane 11 is bonded to the inner wall of the transducer box 30. The first water accumulation double-sided adhesive layer 13 is used to relatively fix the position of the waterproof breathable membrane 11 and the transducer box 30, that is, the first water accumulation double-sided adhesive layer 13 can firmly connect the waterproof component 10 to the inner wall of the transducer box 30, and the waterproof component 10 is not likely to shift or fall off relative to the transducer box 30. And because the connection between the first water accumulation double-sided adhesive layer 13 and the inner wall of the transducer box 30 is relatively tight, it can prevent the liquid in the sound pickup hole 33 from entering the accommodation cavity 31 through the gap between the first water accumulation double-sided adhesive layer 13 and the inner wall of the transducer box 30.

[0044] The second water accumulation double-sided adhesive layer 15 is bonded to the side of the waterproof breathable membrane 11 facing away from the inner wall of the transducer box 30. Both sides of the second water accumulation double-sided adhesive layer 15 have adhesiveness. When the waterproof component 10 is installed on the inner wall of the transducer box 30, the side of the second water accumulation double-sided adhesive layer 15 facing away from the waterproof breathable membrane 11 can be bonded to the support member 70 of the transducer structure 100, and 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.

[0045] The first water-accumulating double-sided adhesive layer 13 and the second water-accumulating double-sided adhesive layer 15 can both maintain good adhesion in water, so that even if the liquid in the sound pickup hole 33 enters the first water-accumulating double-sided adhesive layer 13 and / or the second water-accumulating double-sided adhesive layer 15, the waterproof component 10 can still maintain a fixed connection with the inner wall of the transducer box 30 and the microphone 50, so that the waterproof breathable membrane 11 can effectively prevent the liquid in the sound pickup hole 33 from entering the microphone 50, and the transducer structure 100 has a good waterproof effect. When the waterproof component 10 is connected to the inner wall of the transducer box 30 and the support member 70 of the transducer structure 100 by bonding, there is no need to set a more complicated connection structure on the transducer box 30 and the support member 70, and the overall structure of the transducer structure 100 is relatively simple and easy to process.

[0046] See also Figure 3 and Figure 4 Furthermore, in some embodiments, the waterproof component 10 also includes a polyethylene terephthalate (PET) layer and a third water-retaining double-sided adhesive layer, the side of the second water-retaining double-sided adhesive layer facing away from the first water-retaining double-sided adhesive layer 13 is bonded to one side of the PET layer, and the third water-retaining double-sided adhesive layer is bonded to the other side of the PET layer.

[0047] At this time, the PET layer is arranged between the second water-accumulating double-sided adhesive layer 15 and the third water-accumulating double-sided adhesive layer, one side of the third water-accumulating double-sided adhesive layer is bonded to the PET, and the other side of the third water-accumulating 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.

[0048] Since the thickness of the waterproof breathable membrane 11 is generally thin, when the user wears the earphones to swim or dive, the transducer structure 100 will be subjected to a certain amount of water pressure, and the water flow entering the sound pickup hole 33 will exert a certain amount of pressure on the waterproof breathable membrane 11, and the waterproof breathable membrane 11 is easily damaged. When a PET layer is provided on the side of the first water-accumulating double-sided adhesive layer 13 away from the inner side of the transducer box 30, the PET layer can support and fix the waterproof breathable membrane 11, so that when the water flow squeezes the waterproof breathable end, the waterproof breathable membrane 11 is not easily damaged, so that the waterproof breathable membrane 11 can effectively prevent the liquid in the sound pickup hole 33 from flowing toward the microphone 50. When the waterproof component 10 includes a PET layer, the bone conduction earphone 1000 can be used in a diving environment at a certain depth, the waterproof breathable membrane 11 is not easily damaged, and the microphone 50 is not easily damaged by water ingress, and the user experience is better.

[0049] See also Figure 3 and Figure 4, in some embodiments, the transducer structure 100 further includes a support member 70. The support member 70 is installed in the accommodation 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 faces the inner sidewall of the transducer box 30. The support member 70 is provided with a through hole 73 penetrating through the first side 71 and the second side 72. The first water-accumulating double-sided adhesive layer 13 is provided with a first through hole 131, the second water-accumulating double-sided adhesive layer 15 is provided with a second through hole 151, the third water-accumulating double-sided adhesive layer is provided with a third through hole, and the PET layer is provided with a fourth through hole. The first water-accumulating double-sided adhesive is adhered to the inner sidewall of the transducer box 30. The side of the third water-accumulating double-sided adhesive facing away from the PET layer is adhered to the first side 71 of the support member 70. The microphone 50 is installed on the second side 72 of the support member 70. The sound pickup hole 33, the first through hole 131, the waterproof breathable membrane 11, the second through hole 151, the fourth through hole, the third through hole, the through hole 73, and the microphone 50 are sequentially corresponding in the axial direction of the sound pickup hole 33.

[0050] The support member 70 has a certain structural strength. When the side of the third water-accumulating double-sided adhesive facing away from the PET layer is adhered to the first side 71 of the support member 70, the support member 70 can play a certain bearing role on the waterproof component 10, and the waterproof component 10 is not easily damaged under the extrusion of water flow. In the present application, the support member 70 is a circuit board, the waterproof component 10 is adhered 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.

[0051] The sound pickup hole 33, the first through hole 131, the second through hole 151, the fourth through hole, the third through hole, and the through hole 73 are all used to enable the microphone 50 to pick up sound better, and the through hole 73 is communicated with the microphone channel 55. When the user speaks, the user's voice sequentially passes through the sound pickup hole 33, the first through hole 131, the waterproof breathable membrane 11, the second through hole 151, the fourth through hole, the third through hole, and the through hole 73, and enters the microphone channel 55, so that the microphone 50 can pick up the sound.

[0052] In other embodiments, when the waterproof component 10 does not include the PET layer and the third water-accumulating double-sided adhesive layer, in the axial direction of the sound pickup hole 33, the sound pickup hole 33, the first through hole 131, the second through hole 151, and the through hole 73 are sequentially corresponding. When the user speaks, the user's voice passes through the sound pickup hole 33, the first through hole 131, the waterproof breathable membrane 11, the second through hole 151, and the through hole 73, and enters the microphone channel 55, so that the microphone 50 can pick up the sound.

[0053] Please refer to Figure 3 and Figure 4, in some embodiments, the aperture diameters of the first through hole 131, the second through hole 151, the third through hole, and the fourth through hole are all larger than the aperture diameter of the sound pickup hole 33. At this time, it is convenient to install the waterproof component 10. When the waterproof component 10 is adhered to the inner wall of the transducer box 30, the waterproof component 10 does not need to be accurately aligned with the sound pickup hole 33, and the installation of the waterproof component 10 is relatively simple and the installation efficiency is relatively high.

[0054] Please refer to Figure 3 and Figure 4 , further, in some embodiments, a positioning groove 39 is provided on the inner side wall of the transducer box 30. The positioning groove 39 communicates with the sound pickup hole 33, and the waterproof component 10 is installed in the positioning groove 39. The positioning groove 39 is recessed from the inner side wall of the transducer box 30 toward the outer side wall of the transducer box 30, and the positioning groove 39 is used for installing the waterproof component 10 therein. The positioning groove 39 can play a good positioning role for the waterproof component 10, and can effectively avoid the problem that the waterproof component 10 is displaced during installation.

[0055] Please refer to Figure 3 and Figure 4 , in some embodiments, the microphone 50 includes a first microphone 51 and a second microphone 53, the waterproof component 10 includes a first waterproof component 101 and a second waterproof component 103, the side wall of the transducer box 30 includes an adjacent bottom side wall 35 and a peripheral side wall 37, the sound pickup hole 33 includes a first sound pickup hole 331 provided on the bottom side wall 35 and a second sound pickup hole 333 provided on the peripheral side wall 37. The first microphone 51 faces the first waterproof component 101, the first waterproof component 101 includes a first waterproof breathable membrane 11, and the first waterproof breathable membrane 11 covers the first sound pickup hole 331; the second microphone 53 faces the second waterproof component 103, the second waterproof component 103 includes a second waterproof breathable membrane 11, and the second waterproof breathable membrane 11 covers the second sound pickup hole 333.

[0056] When the microphone 50 includes a first microphone 51 and a second microphone 53, the microphone 50 has a better sound pickup effect on the user's voice. The first waterproof breathable membrane 11 is used to prevent external liquid in the first sound pickup hole 331 from flowing into the first microphone 51, and the second waterproof breathable membrane 11 is used to prevent external liquid in the second sound pickup hole 333 from flowing into the second microphone 53. The waterproof performance of the transducer structure 100 is relatively good, and both the first microphone 51 and the second microphone 53 are not easily damaged. The distances between the first microphone 51 and the second microphone 53 of the present application are relatively far and the angles are staggered, which can effectively avoid interference between the two microphones 50, and the noise of the microphone 50 during sound collection is relatively small.

[0057] Please refer to Figure 3 and Figure 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 installed on opposite sides of the first support member 701, and the second microphone 53 and the second waterproof component 103 are respectively installed on opposite sides of the second support member 703. Both the first support member 701 and the second support member 703 of the present application are circuit boards. The first support member 701 supports and electrically connects the first microphone 51, and the first support member 701 is also used to support the first waterproof component 101. The second support member 703 supports and electrically connects the second microphone 53, and the second support member 703 is also used to support the second waterproof component 103. The first support member 701 and the second support member 703 can be connected by an electrical connector 705. Exemplarily, 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 is convenient to change the relative positions between the first support member 701 and the second support member 703.
