Transducer assembly, headphones, and headphone system

[0001] Priority information

[0002] This application claims priority and benefits to patent application No. 2024221346954, filed with the China National Intellectual Property Administration on August 30, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of headphone technology, and more specifically, to a transducer, headphones, and headphone system. Background Technology

[0004] Bone conduction headphones are headphones that transmit sound directly to the auditory organs through the human skeleton, bypassing the external auditory canal and eardrum. Bone conduction headphones convert sound into mechanical vibrations. When the headphones are in operation, the transducer component, which is in contact with the skin, vibrates. This vibration is transmitted through the skin, subcutaneous tissue, and bones to the auditory nerve, allowing the user to hear sounds. Because bone conduction headphones do not require eardrum vibration, they offer improved comfort, protect the user's hearing, and allow the user to still hear external sounds, giving them unique advantages. The transducer housing and its internal support are typically connected by adhesive. However, excessive adhesive can cause overflow during connection, affecting the overall appearance of the headphones and making cleaning difficult. Summary of the Invention

[0005] This application provides a transducer component, headphones, and a headphone system.

[0006] The transducer assembly of this application includes a first housing, a second housing, and a bracket. The second housing is connected to the first housing and together they form a receiving cavity. The bracket is located within the receiving cavity and is connected to the second housing. The bracket and the first housing together form a mounting cavity. The bracket has a through hole, and the mounting cavity has an adhesive receiving portion. The through hole corresponds to the adhesive receiving portion.

[0007] In some embodiments, the adhesive-containing portion is provided with an adhesive-containing space, which communicates with the through hole.

[0008] In some embodiments, the adhesive-containing portion is connected to the inner wall of the first housing, and the adhesive-containing portion and the inner wall of the first housing together form the adhesive-containing space. The first housing is provided with a through hole, which communicates with the adhesive-containing space. The through hole is used for the power supply connector to enter the receiving cavity through the adhesive-containing space.

[0009] In some embodiments, at least a portion of the adhesive-containing portion is spaced from the inner wall of the first housing and forms a first opening and a second opening, the adhesive-containing space communicating with the through hole through the first opening and the through hole through the second opening.

[0010] In some embodiments, the transducer assembly further includes a vibration component located within the mounting cavity and connected to the bracket, the vibration component being energized to vibrate.

[0011] In some embodiments, the vibrating component includes a coil, a magnetic element, and a spring. The coil is fixedly connected to the bracket and surrounds the magnetic element. The coil is also electrically connected to an electrical connector. The spring is connected to both the bracket and the magnetic element. The magnetic field generated by the energized coil and the magnetic field of the magnetic element are coupled to drive the magnetic element to move. When the energizing direction of the coil changes, the magnetic element can drive the spring to vibrate.

[0012] In some embodiments, the transducer assembly further includes a protective element connected to and surrounding the magnetic element and the coil.

[0013] In some embodiments, the vibration component further includes a connector, the magnetic component has a first through hole, the spring has a second through hole, and the protective component has a third through hole. The first through hole, the second through hole, and the third through hole are all corresponding. The connector passes through the first through hole, the second through hole, and the third through hole so that the magnetic component is connected to both the spring and the protective component.

[0014] In some embodiments, the vibration component further includes a first magnetic conductor and a second magnetic conductor, both of which are disposed between the magnetic component and the spring sheet. The first magnetic conductor and the second magnetic conductor are used to stably transmit the magnetic field of the coil to the magnetic component.

[0015] In some embodiments, the connector sequentially passes through the spring, the first magnetic conductive element, the second magnetic conductive element, the magnetic element, and the protective element, so that the spring, the first magnetic conductive element, the second magnetic conductive element, the magnetic element, and the protective element are fixedly connected.

[0016] The earphones in this application include the transducer assembly described in the above embodiments.

[0017] In some embodiments, the headphones include bone conduction headphones and air conduction headphones.

[0018] The headphone system of this application includes the headphone and charging case described in the above embodiments, wherein the charging case is used to charge the headphone.

[0019] In the transducer assembly, earphone, and earphone system of this application, the bracket has a through hole, and the mounting cavity has an adhesive-containing portion. The through hole corresponds to and communicates with the adhesive-containing portion. The bracket and the second housing can be bonded together with waterproof adhesive. When the bracket and the second housing are connected and the bracket and the second housing jointly compress the waterproof adhesive, the waterproof adhesive can flow into the adhesive-containing portion through the through hole and be stored in the adhesive-containing portion. This avoids the problem of waterproof adhesive overflowing from the bracket and the second housing onto the surface of the transducer assembly, resulting in a better overall aesthetic appearance of the transducer assembly. Furthermore, there is no need to clean the waterproof adhesive on the surface of the transducer assembly, making the installation of the transducer assembly relatively simple.

[0034] Bone conduction headphones are headphones that transmit sound directly to the auditory organs through the human skeleton, bypassing the external auditory canal and eardrum. Bone conduction headphones convert sound into mechanical vibrations; when the headphones are in operation, the transducer component, which is in contact with the skin, vibrates. This vibration is transmitted through the skin, subcutaneous tissue, and bones to the auditory nerve, allowing the user to hear sounds. Since bone conduction headphones do not require eardrum vibration, they offer improved comfort, protect the user's hearing, and allow the user to still hear external sounds, giving them unique advantages. The transducer component's housing and internal support are typically connected by adhesive. However, excessive adhesive can cause overflow during connection, affecting the headphone's appearance and making cleaning difficult. To address this issue, this application provides a transducer component 100 (shown in Figure 2), headphones 1000 (shown in Figure 1), and a headphone system 10000 (shown in Figure 6).

[0035] Please refer to Figures 1 and 2. The headphones 1000 of this embodiment include a transducer assembly 100. In some embodiments, the headphones 1000 include bone conduction headphones 1000 and air conduction headphones 1000.

[0036] Among them, the bone conduction headphones 1000 use the human skeleton as a medium. The bone conduction headphones 1000 convert sound into mechanical vibrations, which are transmitted through the human skeleton to allow the user to hear. The sound from the bone conduction headphones 1000 acts on the bones, and long-term use will not significantly affect the user's eardrum, effectively protecting the user's hearing. The air conduction headphones 1000 transmit sound through air vibrations, and the air conduction headphones 1000 have better sound quality and penetration. This application uses the bone conduction headphones 1000 as an example for illustration, and the bone conduction headphones 1000 of this application can be swimming headphones 1000, allowing users to wear them while swimming and diving. The bone conduction headphones 1000 have good waterproof performance.

[0037] Please refer to Figures 1 and 2. The transducer component 100 of this application is designed to fit in contact with human skin. When the headphones 1000 are in use, the transducer component 100 can generate vibrations, which are transmitted through the human skeleton, allowing the user to hear sound. The headphones 1000 of this application also includes a function box assembly 300, which is electrically connected to the transducer component 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 / off of the headphones 1000 and adjust the volume of the headphones 1000. The battery box assembly 303 includes a battery, which powers other components of the headphones 1000 to enable the headphones 1000 to function properly.

[0038] In some embodiments, the earphone 1000 further includes an ear hook 500 and a back hook 700. The ear hook 500 is used for electrically connecting the battery box assembly 303 and the transducer assembly 100, and for electrically connecting the control box assembly 301 and the transducer assembly 100. The back hook 700 is used for electrically connecting the battery box assembly 303 and the control box assembly 301. When a user wears the earphone 1000, the back hook 700 is worn on the head, and the ear hook 500 is worn behind the ear, thereby improving the stability of the earphone 1000 and making it less likely to fall off when the user is outdoors or exercising.

[0039] Please refer to Figures 3 to 5. The transducer assembly 100 of this embodiment includes a first housing 10, a second housing 30, and a bracket 50. The second housing 30 is connected to the first housing 10 and together forms a receiving cavity 31. The bracket 50 is located in the receiving cavity 31 and is connected to the second housing 30. The bracket 50 and the first housing 10 together form a mounting cavity 51. The bracket 50 is provided with a through hole 53. The mounting cavity 51 is provided with a receiving portion 11. The through hole 53 corresponds to and communicates with the receiving portion 11.

[0040] Specifically, the first housing 10 and the second housing 30 can be connected by a snap-fit, interference fit, or adhesive bonding. For example, the first housing 10 and the second housing 30 can be connected by adhesive bonding. Preferably, the first housing 10 and the second housing 30 can be bonded together using waterproof adhesive. In this case, the connection between the first housing 10 and the second housing 30 is more stable, the first housing 10 is less likely to detach from the second housing 30, and the waterproof effect between the first housing 10 and the second housing 30 is better, preventing external liquids from easily entering the receiving cavity 31 through the gap between the first housing 10 and the second housing 30. The receiving cavity 31 is used to house the support 50 and other components of the transducer assembly 100. Since external liquids are less likely to enter the receiving cavity 31, the components within the receiving cavity 31 are less likely to be damaged.

[0041] Please refer to Figures 3 to 5. One side of the bracket 50 is fixedly connected to the second housing 30, and the other side of the bracket 50 is used to install the vibrating component 70 of the transducer assembly 100. Thus, the vibrating component 70 of the transducer assembly 100 can be fixedly connected to the second housing 30 through the bracket 50. In this application, the bracket 50 and the second housing 30 can be connected by adhesive, so the connection between the bracket 50 and the second housing 30 is relatively stable, and it can effectively prevent external liquid from entering the receiving cavity 31 through the gap between the bracket 50 and the second housing 30. When connecting the bracket 50 and the second housing 30, waterproof adhesive can be applied to the side of the bracket 50 facing away from the mounting cavity 51 first, and then the second housing 30 can be pressed tightly onto the bracket 50. The through hole 53 is used to allow the waterproof adhesive between the bracket 50 and the second housing 30 to flow into the adhesive receiving part 11 through the through hole 53, thereby effectively preventing the waterproof adhesive from flowing out through the gap between the bracket 50 and the second housing 30 onto the surface of the transducer 100. The transducer 100 has a better overall appearance and does not require cleaning of the waterproof adhesive on the surface of the transducer 100, making the installation of the transducer 100 relatively simple.

[0042] The number of through holes 53 can be one, two, three, four, or more. When there is only one through hole 53, it can be located at any position on the bracket 50. In this case, the structure of the bracket 50 is relatively simple, and the manufacturing process is relatively easy. When there are multiple through holes 53, they can be evenly or non-evenly distributed on the bracket 50. In this case, there can also be multiple adhesive-containing portions 11, each corresponding to a different through hole 53. The waterproof adhesive on the bracket 50 can quickly enter the adhesive-containing portion 11 through the multiple through holes 53, further preventing the waterproof adhesive between the bracket 50 and the second housing 30 from flowing out onto the surface of the transducer assembly 100.

[0043] Please refer to Figures 3 to 5. The mounting cavity 51 is used to mount the vibrating component 70 and other components of the transducer assembly 100. The adhesive-containing portion 11 is used to contain the waterproof adhesive flowing out of the through hole 53, which can prevent the waterproof adhesive from flowing into other components in the mounting cavity 51 and affecting their normal operation. In some embodiments, the adhesive-containing portion 11 is provided with an adhesive-containing space 111, which communicates with the through hole 53. The adhesive-containing space 111 is used to store the waterproof adhesive flowing from the through hole 53. The side of the bracket 50 facing the mounting cavity 51 abuts against the top wall of the adhesive-containing portion 11. In the thickness direction of the transducer assembly 100, the through hole 53 corresponds to and communicates with the adhesive-containing portion 11. When the bracket 50 is connected to the second housing 30, the bracket 50 and the second housing 30 jointly compress the waterproof adhesive, and the waterproof adhesive can flow directly into the adhesive-containing portion 11 through the through hole 53. Thus, the waterproof adhesive can be effectively prevented from flowing out from the gap between the through hole 53 and the adhesive-containing portion 11.

[0044] In the transducer assembly 100 of this embodiment, the bracket 50 is provided with a through hole 53, and the mounting cavity 51 is provided with an adhesive-containing portion 11. The through hole 53 corresponds to and communicates with the adhesive-containing portion 11. The bracket 50 and the second housing 30 can be bonded together with waterproof adhesive. When the bracket 50 and the second housing 30 are connected and the bracket 50 and the second housing 30 jointly compress the waterproof adhesive, the waterproof adhesive can flow into the adhesive-containing portion 11 through the through hole 53 and be stored in the adhesive-containing portion 11. This avoids the problem of waterproof adhesive overflowing from the bracket 50 and the second housing 30 onto the surface of the transducer assembly 100. The overall aesthetics of the transducer assembly 100 are better, and there is no need to clean the waterproof adhesive on the surface of the transducer assembly 100. The installation of the transducer assembly 100 is relatively simple.

[0045] The transducer assembly 100 will be further described below with reference to the accompanying drawings.

[0046] Please refer to Figures 3 to 5. In some embodiments, the adhesive-containing part 11 is connected to the inner wall of the first housing 10, and the adhesive-containing part 11 and the inner wall of the first housing 10 together form an adhesive-containing space 111. The first housing 10 is provided with a through hole 13, which communicates with the adhesive-containing space 111. The through hole 13 is used for the power supply connector 90 to enter the receiving cavity 31 through the adhesive-containing space 111.

[0047] The adhesive-containing part 11 can be integrally formed with or separate from the first housing 10. When the adhesive-containing part 11 and the first housing 10 are integrally formed, the processing steps of the transducer assembly 100 are relatively simple, and the connection between the adhesive-containing part 11 and the first housing 10 is relatively stable. When the adhesive-containing part 11 and the first housing 10 are separate, they can be detachably or non-detachably connected. Detachable installation methods include, but are not limited to, threaded connections, screw connections, or snap-fit ​​connections. Non-detachable installation methods include, but are not limited to, welding, adhesive bonding, or interference fits.

[0048] The perforation 13 allows one end of the ear hook 500 to extend into it. The ear hook 500 contains an electrical connector 90. When the ear hook 500 extends into the perforation 13 to connect with the transducer assembly 100, the electrical connector 90 can extend into the receiving cavity 31 to electrically connect with the components within the receiving cavity 31. Because the adhesive space 111 stores waterproof adhesive, when the electrical connector 90 enters the receiving cavity 31 through the adhesive space 111, the portion of the electrical connector 90 located within the adhesive space 111 will be fixed by the waterproof adhesive, thereby preventing the electrical connector 90 within the receiving cavity 31 from shaking or vibrating and causing noise.

[0049] Referring to Figure 5, in some embodiments, at least a portion of the adhesive-containing portion 11 is spaced from the inner wall of the first housing 10 and forms a first opening 113 and a second opening 115. The adhesive-containing space 111 communicates with the through hole 53 through the first opening 113 and with the perforation 13 through the second opening 115.

[0050] The first opening 113 corresponds to and communicates with the through hole 53. During the connection between the bracket 50 and the second housing 30, the through hole 53 allows the waterproof adhesive to flow to the first opening 113 and then into the adhesive-containing space 111. In the longitudinal direction of the transducer assembly 100, the adhesive-containing portion 11 and the through hole 13 are staggered, thereby avoiding the problem of the adhesive-containing portion 11 obstructing the electrical connector 90 from extending into the receiving cavity 31. A second opening 115 is provided on the side of the adhesive-containing portion 11 near the through hole 13. The electrical connector 90 can enter the adhesive-containing space 111 through the second opening 115 and extend into the receiving cavity 31 from the first opening 113, thus allowing the electrical connector 90 to be electrically connected to the components within the receiving cavity 31.

[0051] Please refer to Figures 4 and 5. Further, in some embodiments, the transducer assembly 100 also includes a vibration component 70, which is located in the mounting cavity 51 and connected to the bracket 50. The vibration component 70 can vibrate when energized.

[0052] Electrical connector 90 extends into receiving cavity 31 and can be electrically connected to vibrating component 70. When the earphone 1000 is in use, electrical connector 90 can supply power to vibrating component 70, thereby causing vibrating component 70 to vibrate. At least a portion of vibrating component 70 is connected to bracket 50. When vibrating component 70, vibrating component 70 drives bracket 50 to vibrate, thereby bracket 50 can drive first housing 10 and second housing 30 to vibrate together. When the user wears earphone 1000, second housing 30 can fit in contact with human skin, and the vibration of second housing 30 can be conducted through human bones, thereby allowing the user to hear sound. With bracket 50 having through hole 53 and mounting cavity 51 having adhesive portion 11, the problem of waterproof adhesive on bracket 50 flowing into vibrating component 70 and affecting the normal operation (vibration) of vibrating component 70 can be effectively prevented.

[0053] Please refer to Figures 4 and 5. In some embodiments, the vibrating component 70 includes a coil 72, a magnetic element 73, and a spring 75. The coil 72 is fixedly connected to the bracket 50 and surrounds the magnetic element 73. The coil 72 is also electrically connected to the electrical connector 90. The spring 75 is connected to both the bracket 50 and the magnetic element 73. The magnetic field generated by the energized coil 72 and the magnetic field of the magnetic element 73 are coupled to drive the magnetic element 73 to move. When the energizing direction of the coil 72 changes, the magnetic element 73 can drive the spring 75 to vibrate.

[0054] Specifically, the coil 72 can be fixedly connected to the side of the bracket 50 facing the mounting cavity 51 by adhesive bonding. In this case, the structure of the bracket 50 is relatively simple, no connecting structure needs to be designed on the bracket 50, and the connection between the coil 72 and the bracket 50 is relatively stable. When both the vibrating component 70 and the bracket 50 vibrate, the coil 72 is not easy to loosen relative to the bracket 50. When the coil 72 surrounds the magnetic component 73, the coupling effect between the magnetic field of the coil 72 and the magnetic field of the magnetic component 73 is good, and the coil 72 can effectively drive the magnetic component 73 to move.

[0055] For example, when current flows through coil 72 in a first direction, the coupling of the magnetic field of coil 72 and the magnetic field of magnetic element 73 causes magnetic element 73 to move towards the second housing 30. When current flows through coil 72 in a second direction, the coupling of the magnetic field of coil 72 and the magnetic field of magnetic element 73 causes magnetic element 73 to move towards the first housing 10, the first direction being opposite to the second direction. When the direction of the current supplied to coil 72 by electrical connector 90 alternates between the first and second directions, magnetic element 73 can move repeatedly and vibrate. When magnetic element 73 is connected to spring 75, spring 75 can vibrate along with magnetic element 73. When spring 75 vibrates, it can drive bracket 50 to vibrate, thereby causing bracket 50 to drive the first housing 10 and the second housing 30 to vibrate together. The vibration of the first housing 10 can be conducted through the human skeleton, allowing the user to hear sound.

[0056] The spring 75 can be a one-piece structure. For example, the spring 75 can be formed by punching and blanking metal sheet. Depending on the actual needs, the spring 75 can be formed by punching and blanking stainless steel sheet. The spring 75 of this application is generally a thin plate structure. The magnetic component 73 can be a permanent magnet, which can be a ferrite magnet or a neodymium iron boron magnet, etc. The magnetic component 73 of this application is generally flat.

[0057] Referring to Figures 4 and 5, in some embodiments, the transducer assembly 100 further includes a protective element 71 located within the mounting cavity 51 and connected to the magnetic element 73. The protective element 71 surrounds the magnetic element 73 and the coil 72. The protective element 71 may be made of a magnetic shielding material. When the magnetic field of the coil 72 and the magnetic field of the magnetic element 73 are coupled, the protective element 71 can be used to prevent the magnetic fields of the coil 72 and the magnetic element 73 from leaking out, thereby avoiding magnetic field interference with the operation of other components within the mounting cavity 51.

[0058] Please refer to Figures 4 and 5. In some embodiments, the vibration component 70 further includes a connector 77, the magnetic component 73 is provided with a first through hole 731, the spring piece 75 is provided with a second through hole 751, and the protective component 71 is provided with a third through hole 713. The first through hole 731, the second through hole 751 and the third through hole 713 are all corresponding. The connector 77 passes through the first through hole 731, the second through hole 751 and the third through hole 713 so that the magnetic component 73 is connected to both the spring piece 75 and the protective component 71.

[0059] The connector 77 is used to securely connect the magnetic component 73, the spring 75, and the protective component 71. When the magnetic component 73 vibrates, it facilitates the vibration of the spring 75. Simultaneously, the magnetic component 73 can also drive the protective component 71 to vibrate, thus maintaining a relatively fixed relationship between the magnetic component 73 and the protective component 71. The protective component 71 effectively prevents the magnetic field of the magnetic component 73 from leaking out. The connector 77 can be made of non-magnetic material, for example, stainless steel or aluminum alloy.

[0060] Please refer to Figures 4 and 5. In some embodiments, the connector 77 is provided with a fourth through hole 771. The fourth through hole 771 can communicate with the space between the second housing 30 and the bracket 50, and the space between the vibrating component 70 and the first housing 10, so that the air pressure at both ends of the magnetic component 73 remains consistent.

[0061] When the transducer 100 is in use, the vibration component vibrates back and forth within the accommodating cavity 31. During the back-and-forth vibration of the vibration component 70, the air pressure values ​​on both sides of the magnetic component 73 (vibration component 70) are kept consistent through the fourth perforation 771, thus avoiding the problem of poor vibration of the vibration component 70 due to differences in air pressure values ​​on both sides of the magnetic component 73. By providing the fourth perforation 771 in the connector 77, balanced vibration of the vibration component 70 can be ensured, thereby improving the accuracy of the transducer response of the bone conduction headphones 1000 and enhancing the performance of the bone conduction headphones 1000.

[0062] Please refer to Figures 4 and 5. Further, in some embodiments, the vibration component 70 also includes a first magnetic conductor 78 and a second magnetic conductor 79. The first magnetic conductor 78 and the second magnetic conductor 79 are both disposed between the magnetic component 73 and the spring piece 75. The first magnetic conductor 78 and the second magnetic conductor 79 are used to stably transmit the magnetic field of the coil 72 to the magnetic component 73.

[0063] The first magnetic conductive element 78 is roughly shaped like a thin flat plate and is made of a magnetically conductive material. The second magnetic conductive element 79 is also roughly shaped like a thin flat plate and is made of a magnetically conductive material. By setting the first magnetic conductive element 78 and the second magnetic conductive element 79, the magnetic field generated by the coil 72 can be stably transmitted to the magnetic element 73, thereby improving the utilization rate of magnetic field energy and ensuring the timeliness and efficiency of the vibration of the vibrating component 70.

[0064] Please refer to Figures 4 and 5. In some embodiments, the connector 77 sequentially passes through the spring piece 75, the first magnetic conductor 78, the second magnetic conductor 79, the magnetic component 73, and the protective component 71, so that the spring piece 75, the first magnetic conductor 78, the second magnetic conductor 79, the magnetic component 73, and the protective component 71 are fixedly connected.

[0065] The connection between the spring 75, the first magnetic conductor 78, the second magnetic conductor 79, the magnetic component 73, and the protective component 71 is relatively tight. When the magnetic component 73 vibrates, it can drive the spring 75, the first magnetic conductor 78, the second magnetic conductor 79, and the protective component 71 to vibrate together. Furthermore, the vibrating component 70 does not require multiple connecting structures to connect the spring 75, the first magnetic conductor 78, the second magnetic conductor 79, the magnetic component 73, and the protective component 71, making the structure of the vibrating component 70 relatively simple.

[0066] Please refer to Figure 6. The headphone system 10000 of this application embodiment includes the headphone 1000 and charging case 3000 of the above embodiment. The charging case 3000 is used to charge the headphone 1000. The charging case 3000 is provided with a charging compartment. When the headphone 1000 needs to be charged, the battery compartment of the headphone 1000 can be accommodated in the charging compartment, and the charging case 3000 can charge the battery inside the battery compartment.

[0067] In the headphone system 10000 of this application embodiment, the bracket 50 is provided with a through hole 53, and the mounting cavity 51 is provided with an adhesive-containing portion 11. The through hole 53 corresponds to and communicates with the adhesive-containing portion 11. The bracket 50 and the second housing 30 can be bonded together with waterproof adhesive. When the bracket 50 and the second housing 30 are connected, and the bracket 50 and the second housing 30 jointly compress the waterproof adhesive, the waterproof adhesive can flow into the adhesive-containing portion 11 through the through hole 53 and be stored in the adhesive-containing portion 11. This avoids the problem of waterproof adhesive overflowing from the bracket 50 and the second housing 30 onto the surface of the transducer assembly 100. The overall aesthetics of the transducer assembly 100 are better, and there is no need to clean the waterproof adhesive on the surface of the transducer assembly 100. The installation of the transducer assembly 100 is relatively simple.
