Abstract
Description
Technical Field
[0001] This application relates to the field of headphone technology, and more specifically, to a transducer, headphones, and headphone system. Background Technology
[0002] Wireless headphones have captured a significant market share in the headphone industry due to their portability and lightweight design. When headphones interact with external devices, such as during charging or data transfer, the electrical connectors on the headphones must align with the electrical connectors in the external device's circuitry to establish electrical transmission. This connection is achieved through the magnetic attraction between a magnetic component located inside the transducer assembly and a magnetic attraction component inside the external device. However, to achieve miniaturization, the magnetic component is typically small and located only in a small area around the electrical connector, resulting in a weak magnetic attraction and a weak bond between the headphones and the external device. Therefore, if the headphones shift position due to vibration or accidental contact during interaction, the interaction will fail because the electrical connectors are not aligned, impacting the user experience. Utility Model Content
[0003] This application provides a transducer component, headphones, and headphone system to solve at least one of the aforementioned technical problems.
[0004] The transducer assembly provided in this application is for headphones. The transducer assembly includes a body, two electrical connectors, and a T-shaped magnetic chuck. The body has a receiving cavity. The two electrical connectors are housed within the receiving cavity and spaced apart from each other. The electrical connectors are configured to be electrically connected to an external circuit. The magnetic chuck is housed within the receiving cavity and includes a main body portion and two extension portions. The main body portion includes a first side and a second side opposite to each other in a first direction. The two extension portions extend from the first side and the second side of the main body portion along the first direction, respectively. The two electrical connectors are located on the first side and the second side of the main body portion, respectively.
[0005] In some embodiments, the electrical connector is open on both sides and surrounded by the magnetic attractor. In the first direction, the electrical connector does not extend beyond the extension.
[0006] In some embodiments, the electrical connector is open on both sides and surrounded by the magnetic attractor. In a second direction, the electrical connector does not extend beyond the main body, and the second direction is perpendicular to the first direction.
[0007] In some embodiments, in the first direction, the size of the main body portion is greater than or equal to the size of each of the extension portions.
[0008] In some embodiments, the body includes an inner surface and an outer surface in the thickness direction, the inner surface being located within the accommodating cavity. The main body portion includes a first surface and a second surface opposite to each other in the thickness direction. The first surface of the main body portion is fitted to the inner surface, and the inner surface, the outer surface, and the first surface of the main body portion are all planar.
[0009] In some embodiments, the transducer assembly further includes a limiting component extending from the inner surface of the body within the receiving cavity and forming a receiving groove. The magnetic attractor is received in the receiving groove, and the limiting component is configured to restrict movement of the magnetic attractor in a plane perpendicular to the thickness direction of the transducer assembly.
[0010] In some embodiments, the limiting component includes a limiting member and a blocking member. The limiting member is located between the electrical connector and the magnetic attractor in a direction perpendicular to the thickness direction. The inner contour of the limiting member matches the outer contour of the magnetic attractor and is configured to restrict forward and reverse movement of the magnetic attractor along the first direction, and to restrict forward movement of the magnetic attractor along the second direction. The blocking member is connected to the limiting member and / or the main body, abuts against the magnetic attractor, and is configured to restrict reverse movement of the magnetic attractor along the second direction, which is perpendicular to the first direction.
[0011] In some embodiments, the main body portion has mating surfaces between its opposite sides in the first direction and the side of the extension portion facing the electrical connector. The limiting member includes a first limiting portion, a second limiting portion, and a guide portion. The first limiting portion has a first sub-slot, in which at least a portion of the main body portion of the magnetic attractor is received. The second limiting portion has a second sub-slot, in which the extension portion of the magnetic attractor is received. In the first direction, the inner dimension of the second sub-slot is larger than the inner dimension of the first sub-slot. The guide portion connects the first limiting portion and the second limiting portion, forming a third sub-slot. The third sub-slot connects the first sub-slot and the second sub-slot, and together with the first sub-slot and the second sub-slot, forms the receiving groove. The guide portion is configured to guide the magnetic attractor into the receiving groove when the magnetic attractor is inserted into the receiving groove, and the guide portion mates with the mating surfaces.
[0012] In some embodiments, the size of the barrier is smaller than the height of the limiting member in the thickness direction of the transducer assembly.
[0013] In some embodiments, the size of the magnetic attractor is smaller than the height of the limiting member in the thickness direction of the transducer assembly.
[0014] In some embodiments, the size of the barrier is smaller than the size of the extension in the first direction.
[0015] In some embodiments, the limiting member and / or the blocking member are provided with a magnetic shielding layer.
[0016] The headphones provided in this application include the transducer component described in any of the above embodiments.
[0017] The headphone system provided in this application includes the headphone and charging device described in any of the above embodiments, wherein the charging device is used to charge the headphone.
[0018] In the transducer assembly, earphone, and earphone system of this application, two electrical connectors are housed within a receiving cavity and separated by a T-shaped magnetic chuck. The two electrical connectors are configured to be electrically connected to an external circuit to enable interaction between the earphone and an external device. Since the magnetic chuck includes a main body and two extensions extending from both sides of the main body, compared to a magnetic chuck without extensions, the magnetic chuck of this application is larger in volume and is disposed over a larger area around the electrical connector. This results in a stronger magnetic attraction between the earphone and the external device, a stronger bond between the earphone and the external device, and less likelihood of the earphone changing position with the external device, thus ensuring a stable interaction process.

[0037] Wireless headphones have captured a significant market share in the headphone industry due to their portability and lightweight design. When headphones interact with external devices, such as during charging or data transfer, the electrical connectors on the headphones must align with the electrical connectors of the external circuitry in the external device to achieve electrical transmission. This connection is achieved through the magnetic attraction between a magnetic component located inside the transducer assembly and a magnetic attraction component inside the external device. However, to achieve miniaturization, the magnetic component is typically small and located only in a small area around the electrical connector, resulting in a weak magnetic attraction between the headphones and the external device and a low bonding strength. Therefore, if the headphones shift position due to vibration or accidental contact during interaction, the interaction will fail because the electrical connectors are not aligned, impacting the user experience. To address these issues, this application provides a transducer assembly 100 (… Figure 3 (as shown), headphones 1000 ( Figure 2 (as shown) and headphone system 10000 ( Figure 1 (As shown).
[0038] Please refer to Figure 1 and Figure 2 The headphone system 10000 provided in this application includes a headphone 1000 and a charging device 3000. The charging device 3000 is used to charge the headphone 1000.
[0039] It is understood that the charging device 3000 is a device in the headphone system 10000 used to charge or store the headphones 1000. For example, when the headphones 1000 are low on power or not needed, the user can place them in the charging device 3000. The headphones 1000 can be worn on the user's ears and can be used with devices such as mobile phones, computers, smart wearable devices (such as smartwatches, smart bracelets, smart glasses, and smart helmets), head-mounted displays, and virtual reality devices. In some embodiments of this application, the headphones 1000 may include, but are not limited to, ear-hook headphones.
[0040] Since the headphone system 10000 in this embodiment includes a headphone 1000, it is understood that the headphone system 10000 includes at least the same beneficial effects as the headphone 1000. Therefore, for the beneficial effects of the headphone system 10000, please refer to the beneficial effects of the headphone 1000 described below.
[0041] Please refer to Figures 1 to 3 The headphones 1000 provided in this application include a transducer component 100. It is understood that the transducer component 100 is a structure in the headphones 1000 used to enable the user to hear sound. That is, the transducer component 100 is a structure in the headphones 1000 capable of converting electrical signals into sound waves, and its performance directly determines the sound quality of the headphones 1000. Specifically, the headphones 1000 includes one transducer component 100; or, the headphones 1000 includes two transducer components 100. For example, in the case where the headphones 1000 are ear-hook headphones, the headphones 1000 include one transducer component 100.
[0042] It should be noted that the user's ear includes 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. When the earphone 1000 is an ear-hook type, and the earphone 1000 is in a wearing state, the transducer component 100 is configured to at least partially extend into at least one of the concha, cymba conchae, or triangular fossa.
[0043] In some embodiments of this application, the earphone 1000 is an ear-hook type earphone. The earphone 1000 further includes an ear-hook assembly 300, which includes an ear-hook piece 310 and a power supply piece 330, with the power supply piece 330 disposed within the ear-hook piece 310. In the wearing state, the transducer 100 can be located within the concha and / or triangular fossa of the ear. The ear-hook piece 310 is suspended between the back of the user's ear and head. The ear-hook piece 310 and the transducer 100 together elastically hold the ear, which helps to increase the stability and comfort of wearing the earphone and reduces the possibility of the earphone 1000 falling off during wear.
[0044] It should be noted that, in some embodiments, the power supply component 330 can be a rechargeable battery, including but not limited to lithium-ion batteries, nickel-metal hydride batteries, and nickel-cadmium batteries. The ear hook 310 may be provided with a conductive element, and the power supply component 330 can be electrically connected to the transducer assembly 100 through the conductive element to supply power to the transducer assembly 100. The conductive element can be spring steel, titanium wire, etc., and this application does not impose any limitations.
[0045] Since the earphone 1000 in this embodiment includes a transducer component 100, it is understood that the earphone 1000 has at least the same beneficial effects as the transducer component 100. Therefore, for the beneficial effects of the earphone 1000, please refer to the beneficial effects of the transducer component 100 described below.
[0046] Please refer to Figures 3 to 5 The transducer assembly 100 provided in this application is used in an earphone 1000. The transducer assembly 100 includes a body 10, two electrical connectors 30, and a T-shaped magnetic chuck 50. The body 10 has a receiving cavity 11. The two electrical connectors 30 are housed in the receiving cavity 11 and spaced apart from each other. The electrical connectors 30 are configured to be electrically connected to an external circuit. The magnetic chuck 50 is housed in the receiving cavity 11 and includes a main body 51 and two extensions 53. The main body 51 includes a first side 511 and a second side 513 opposite to each other in a first direction X. The two extensions 53 extend from the first side 511 and the second side 513 of the main body 51 along the first direction X, respectively. The two electrical connectors 30 are located on the first side 511 and the second side 513 of the main body 51, respectively.
[0047] Specifically, the body 10 is a component in the transducer assembly 100 used to house elements other than the body 10, such as the electrical connector 30 (partially housed within the body 10 and partially extending from within the body 10) and the magnetic connector 50. The body 10 can be made of, but is not limited to, one or more combinations of, plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. For example, the body 10 is made of plastic, which makes the transducer assembly 100 lighter, reduces its weight, and improves the wearing comfort of the headphones 1000. The body 10 is the main body of the transducer assembly 100, and the accommodating space structure formed by the body 10 is the accommodating cavity 11.
[0048] Electrical connector 30 is a structure in transducer assembly 100 used to electrically connect transducer assembly 100 to external circuitry via electrical connection mating member 3100. Electrical connection mating member 3100 is a component capable of being electrically connected to electrical connector 30. In some embodiments, electrical connector 30 is a charging terminal for charging transducer assembly 100. In this case, the external circuit is an external charging circuit, such as the charging circuit in charging device 3000. Charging device 3000 is provided with electrical connection mating member 3100. When electrical connector 30 is electrically connected to electrical connection mating member 3100, charging device 3000 can transmit electrical energy to power supply member 330 through electrical connection mating member 3100 and electrical connector 30, thereby realizing the charging function of earphone 1000. In other embodiments, the electrical connector 30 is a data terminal for transmitting data to the transducer assembly 100. In this case, the external circuit is an external data transmission circuit, such as a data transmission device (not shown). The data transmission device is provided with an electrical connection mating member. When the electrical connector 30 is electrically connected to the electrical connection mating member, the data transmission device can transmit data with the transducer assembly 100. It should be noted that in some embodiments, the electrical connector 30 may be at least one of the elements capable of electrical connection, such as a spring pin and a spring sheet.
[0049] This application uses electrical connector 30 as an example of a charging terminal for charging the transducer assembly 100. Two electrical connectors 30 are used to ensure a more stable electrical connection between the transducer assembly 100 and the external circuit, and also offer the advantage of miniaturization. Both electrical connectors 30 are partially housed within the receiving cavity 11 and partially extend from the receiving cavity 11 to the outside of the body 10. The two electrical connectors 30 are spaced apart to avoid short circuits that could damage the transducer assembly 100. The electrical connector 30 is connected to the body 10, and this connection can be either detachable or non-detachable. Detachable connections include, but are not limited to, one or more combinations of screw connections and snap-fit connections. Non-detachable connections include, but are not limited to, one or more combinations of gluing, welding, and sintering methods. This definition will be used for detachable and non-detachable connections in the following descriptions.
[0050] The magnetic attractor 50 is a magnetic element and includes two poles with opposite magnetic properties. The magnetic attractor 50 may, but is not limited to, use metallic magnetic materials or rare-earth magnetic materials. The magnetic attractor 50 is housed within the receiving cavity 11 and connected to the body 10. The connection between the magnetic attractor 50 and the body 10 can be detachable or non-detachable. When the transducer assembly 100 is used in conjunction with an external device, such as a charging device 3000, the magnetic attractor 50 can engage with the magnetic structure (not shown) of the charging device 3000 to align the electrical connector 30 with the electrical connection mating part 3100, thereby achieving electrical connection between the electrical connector 30 and the external circuit. At this time, the magnetic poles of the magnetic structure near the magnetic attractor 50 are opposite to the magnetic poles of the magnetic structure near the magnetic attractor 50.
[0051] In this application, the magnetic attractor 50 is T-shaped. Specifically, the main body 51 is the main body of the magnetic attractor 50, that is, the vertical part of the T-shape. In this application, the direction of the line connecting the centers of the two electrical connectors 30 is defined as the first direction X. Please refer to... Figure 4 The first direction X includes two opposite directions, defined as the positive direction X1 and the negative direction X2 of the first direction. In the first direction X, the main body 51 includes a first side 511 and a second side 513, which are opposite to each other. The extension 53 is a structure formed by extending the magnetic attractor 50 from the main body 51 to increase the volume of the magnetic attractor 50, i.e., the horizontal portion in the T-shape. There are two extensions 53, extending from the first side 511 of the main body 51 along the positive direction X1 of the first direction, and from the second side 513 of the main body 51 along the negative direction X2 of the first direction, respectively. At this time, the two electrical connectors 30 are located on the first side 511 and the second side 513 of the main body 51, respectively, and correspond to the two extensions 53.
[0052] In the transducer assembly 100 of this embodiment, two electrical connectors 30 are housed within the receiving cavity 11 and separated by a T-shaped magnetic chuck 50. The two electrical connectors 30 are configured to be electrically connected to an external circuit to enable interaction between the earphone 1000 and an external device. Since the magnetic chuck 50 includes a main body 51 and two extensions 53 extending from both sides of the main body 51, compared to a magnetic component without extensions, the magnetic chuck 50 of this application has a larger volume and is disposed in a larger area around the electrical connectors 30. This results in a stronger magnetic attraction between the earphone 1000 and the external device, a stronger bond between the earphone 1000 and the external device, and a less prone-to-positional change in the earphone 1000 and the external device, thus ensuring a stable interaction process.
[0053] Please refer to Figure 4 and Figure 5In some embodiments, the electrical connector 30 has open sides, which are surrounded by magnetic members 50. Specifically, the electrical connector 30 includes four sides connected end-to-end in a direction surrounding it. Since the magnetic member 50 is T-shaped, the space formed by the main body 51 and the extension 53 is a semi-enclosed space, and the electrical connector 30 is installed in this semi-enclosed space. In this case, the sides of the electrical connector 30 opposite to the magnetic member 50 are not open, and the sides of the electrical connector 30 opposite to the magnetic member 50 are surrounded by the magnetic member 50.
[0054] In some examples, the electrical connector 30 does not extend beyond the extension 53 in the first direction X. In this case, the magnetic field formed by the extension 53 can cover at least a portion of the area surrounding the electrical connector 30 in the first direction X, and the electrical connector 30 does not extend beyond the magnetic field formed by the magnetic attractor 50 (the magnetic field formed by the extension 53) in the first direction X. Therefore, in a plane perpendicular to the thickness direction Z of the transducer 100, the areas where the electrical connector 30 and the magnetic attractor 50 generate magnetic attraction are relatively close, the magnetic attractor 50 can be tightly bonded to the magnetic structure in the charging device 3000, the alignment accuracy between the electrical connector 30 and the electrical connection mating part 3100 is high, the electrical connection between the electrical connector 30 and the electrical connection mating part 3100 of the charging device 3000 is stable, and the charging device 3000 charges the transducer 100 with high efficiency.
[0055] In other examples, in the second direction Y, the electrical connector 30 does not extend beyond the main body 51, and the second direction Y is perpendicular to the first direction X. The second direction Y is defined as the direction perpendicular to both the thickness direction Z of the transducer 100 and the first direction X. In this case, the magnetic field generated by the main body 51 can cover at least a portion of the area surrounding the electrical connector 30 in the second direction Y, and the electrical connector 30 does not extend beyond the magnetic field generated by the magnetic attractor 50 (the magnetic field generated by the main body 51) in the second direction Y. Therefore, in a plane perpendicular to the thickness direction Z of the transducer 100, the areas where the electrical connector 30 and the magnetic attractor 50 generate magnetic attraction are relatively close, the magnetic attractor 50 can be tightly bonded to the magnetic structure in the charging device 3000, the alignment accuracy between the electrical connector 30 and the electrical connection mating part 3100 is high, the electrical connection between the electrical connector 30 and the electrical connection mating part 3100 of the charging device 3000 is stable, and the charging efficiency of the charging device 3000 for charging the transducer 100 is high.
[0056] Please refer to Figure 4 and Figure 5In some embodiments, the size of the main body 51 in the first direction X is greater than or equal to the size of each extension 53. Specifically, the main body 51 is the main part of the magnetic attractor 50, and the size of the main body 51 in the second direction Y is greater than the size of each extension 53. Therefore, when the size of the main body 51 is greater than or equal to the size of each extension 53, the volume of the magnetic attractor 50 is larger in the same mounting space in the first direction X. At this time, the magnetic attraction force between the magnetic attractor 50 and the magnetic structure is greater, and the transducer assembly 100 can be more tightly combined with the charging device 3000. Therefore, the alignment accuracy between the electrical connector 30 and the electrical connection mating member 3100 is higher, the electrical connection between the electrical connector 30 and the electrical connection mating member 3100 of the charging device 3000 is stable, and the charging efficiency of the charging device 3000 for charging the transducer assembly 100 is higher.
[0057] Please refer to Figure 4 and Figure 5 In some embodiments, the body 10 includes an inner surface 13 and an outer surface 15 in the thickness direction Z, with the inner surface 13 located within the receiving cavity 11. The main body portion 51 includes a first surface 515 and a second surface 517 that are opposite to each other in the thickness direction Z. The first surface 515 of the main body portion 51 is in contact with the inner surface 13, and the inner surface 13, the outer surface 15, and the first surface 515 of the main body portion 51 are all planar.
[0058] Specifically, in the above embodiment, the inner surface 13 is the surface of the body 10 located within the accommodating cavity 11 and facing the magnetic attractor 50. The outer surface 15 is the surface of the body 10 facing the outside of the transducer assembly 100. When the transducer assembly 100 is engaged with the charging device 3000, the outer surface 15 contacts at least a portion of the surface of the charging device 3000 to achieve engagement between the magnetic attractor 50 and the magnetic structure, thereby achieving electrical connection between the electrical connector 30 and the electrical connection mating member 3100.
[0059] The magnetic attractor 50 has a certain thickness. In this application, it is taken as an example where the thickness direction Z of the magnetic attractor 50 is the same as the thickness direction Z of the transducer assembly 100. In this case, the installation of the magnetic attractor 50 in the transducer assembly 100 is relatively easy. Hereafter, the thickness direction Z of the magnetic attractor 50 and the thickness direction Z of the transducer assembly 100 will both be referred to as the thickness direction Z, and the thickness direction Z is perpendicular to the first direction X. It can be understood that the thickness direction of the magnetic attractor 50 may also be different from the thickness direction of the transducer assembly 100, and this application does not limit this.
[0060] In the thickness direction Z, the main body 51 includes a first surface 515 and a second surface 517, which are opposite to each other. In the second direction Y, the outer surface 15, the inner surface 13, and the first surface 515 of the main body 51 are sequentially distributed, and the first surface 515 of the main body 51 is in contact with the inner surface 13. When the inner surface 13, the outer surface 15, and the first surface 515 are all planar, the installation of the magnetic suction member 50 with the body 10 is relatively stable, and the cooperation between the transducer assembly 100 and the charging device 3000 is relatively stable.
[0061] Therefore, the transducer 100 of this application has good structural stability when the inner surface 13, outer surface 15, and the first surface 515 of the main body 51 are all planar. On the one hand, the installation of the magnetic suction member 50 and the body 10 is relatively stable, and the service life of the transducer 100 is long. On the other hand, the outer surface 15, which is the mating surface between the transducer 100 and the charging device 3000, has high flatness, and the transducer 100 can be more tightly integrated with the charging device 3000. Therefore, the alignment accuracy between the electrical connector 30 and the electrical connection mating member 3100 is high, the electrical connection between the electrical connector 30 and the electrical connection mating member 3100 of the charging device 3000 is stable, and the charging efficiency of the charging device 3000 for charging the transducer 100 is high.
[0062] Please refer to Figure 4 and Figure 5 In some embodiments, the transducer assembly 100 further includes a limiting component 70, which extends from the inner surface 13 of the body 10 within the receiving cavity 11 and forms a receiving groove 71. The magnetic attractor 50 is received in the receiving groove 71, and the limiting component 70 is configured to restrict the movement of the magnetic attractor 50 in a plane perpendicular to the thickness direction Z of the transducer assembly 100.
[0063] Specifically, the limiting component 70 is a structure in the transducer assembly 100 used to install and limit the position of the magnetic suction member 50. The limiting component 70 extends from the inner surface 13 toward the receiving cavity 11 and is located in the receiving cavity 11. The spatial structure formed by the limiting components 73 is the receiving groove 71, which can be understood as at least a part of the receiving cavity 11. The limiting component 70 is connected to the body 10, and the material of the limiting component 70 and the body 10 can be the same or different. The limiting component 70 and the body 10 can be integrally formed, in which case the transducer assembly 100 has better structural stability and greater structural strength. The limiting component 70 and the body 10 can also be separate structures, in which case the limiting component 70 and the body 10 can be detachably connected or non-detachably connected.
[0064] The outer contour of the magnetic attractor 50 corresponds to the inner contour of the receiving groove 71. The magnetic attractor 50 is installed and accommodated in the receiving groove 71 so that the magnetic attractor 50 is stably disposed in the transducer assembly 100. At this time, at least a portion of the sidewall of the magnetic attractor 50 is opposite to and abuts against the limiting assembly 70. Therefore, the movement of the magnetic attractor 50 in the plane perpendicular to the thickness direction Z is limited by the limiting assembly 70. The limiting component 70 forms a receiving groove 71 for accommodating the magnetic attractor 50. When the magnetic attractor 50 is accommodated in the receiving groove 71, at least a portion of the sidewall of the magnetic attractor 50 abuts against the limiting component 70. Therefore, the limiting component 70 can prevent the magnetic attractor 50 from moving in the plane perpendicular to the thickness direction Z. The transducer component 100 has good structural stability and a long service life. The alignment of the magnetic attractor 50 and the magnetic structure will not change. The alignment accuracy of the electrical connector 30 and the electrical connection mating part 3100 is high. The electrical connection between the electrical connector 30 and the electrical connection mating part 3100 of the charging device 3000 is stable. The charging device 3000 charges the transducer component 100 with high efficiency.
[0065] Please refer to Figure 4 and Figure 5 In some embodiments, the limiting assembly 70 includes a limiting member 73 and a blocking member 75. The limiting member 73 is located between the electrical connector 30 and the magnetic attractor 50 in the direction perpendicular to the thickness direction Z. The inner contour of the limiting member 73 matches the outer contour of the magnetic attractor 50 and is configured to restrict movement of the magnetic attractor 50 in the forward X1 and reverse X2 directions of a first direction, and to restrict movement of the magnetic attractor 50 in the forward Y1 direction of a second direction. The blocking member 75 is connected to the limiting member 73 and / or the main body 51, abuts against the magnetic attractor 50, and is configured to restrict movement of the magnetic attractor 50 in the reverse Y2 direction of the second direction, which is perpendicular to the first direction X.
[0066] Specifically, the limiting member 73 is the main body of the limiting assembly 70, used to restrict the movement of the magnetic member 50 along the first direction X and the positive direction Y1 of the second direction. The limiting member 73 extends from the inner surface 13 toward the receiving cavity 11 to surround at least a portion of the outer contour of the magnetic member 50. The size and shape of the outer contour of the magnetic member 50 match the size and shape of the inner contour of the limiting member 73, respectively. At this time, the magnetic member 50 abuts against at least a portion of the sidewalls of the magnetic member 50 in the positive direction X1, the negative direction X2, and the positive direction Y1 of the first direction. Therefore, the limiting member 73 can restrict the movement of the magnetic member 50 along the positive direction X1 and the negative direction X2 of the first direction, and restrict the movement of the magnetic member 50 along the positive direction Y1 of the second direction.
[0067] The barrier 75 cooperates with the limiting member 73 to further restrict the movement of the magnetic member 50. In some embodiments, the barrier 75 extends from the limiting member 73 and surrounds at least a portion of the outer contour of the magnetic member 50. The barrier 75 and the limiting member 73 can be integrally formed or separately formed. If the barrier 75 and the limiting member 73 are separately formed, they can be detachably connected or non-detachably connected. In other embodiments, the barrier 75 extends from the main body 51 and surrounds at least a portion of the outer contour of the magnetic member 50. The barrier 75 and the main body 51 can be integrally formed or separately formed. If the barrier 75 and the main body 51 are separately formed, they can be detachably connected or non-detachably connected. In still some embodiments, the barrier 75 extends from the limiting member 73 and / or the main body 51 and surrounds at least a portion of the outer contour of the magnetic member 50. The barrier 75 and the main body 51 can be integrally formed or separately formed. If the barrier 75 and the main body 51 are separately formed, they can be detachably connected or non-detachably connected. Similarly, the barrier 75 and the limiting member 73 can be integrally formed or separately formed. If the barrier 75 and the limiting member 73 are separately formed, they can be detachably connected or non-detachably connected. In this case, the magnetic attractor 50 abuts against at least a portion of its sidewall in the reverse direction Y2 of the second direction. Therefore, the barrier 75 can restrict the movement of the magnetic attractor 50 along the reverse direction Y2 of the second direction.
[0068] In summary, the movement of the magnetic attractor 50 along the first direction (forward X1 and reverse X2) and along the second direction (forward Y1 and reverse Y2) is restricted by the limiting member 73 and the blocking member 75. The transducer assembly 100 has good structural stability and a long service life. The alignment of the magnetic attractor 50 with the magnetic structure does not change. The alignment accuracy of the electrical connector 30 and the electrical connection mating member 3100 is high. The electrical connection between the electrical connector 30 and the electrical connection mating member 3100 of the charging device 3000 is stable. The charging device 3000 charges the transducer assembly 100 with high efficiency.
[0069] Please refer to Figure 4 and Figure 5In some embodiments, the main body 51 has mating surfaces 55 between its opposite sides in the first direction X and between the extension 53 and the side facing the electrical connector 30. The limiting member 73 includes a first limiting part 731, a second limiting part 733, and a guide part 735. The first limiting part 731 has a first sub-groove 711, in which the main body 51 of the magnetic attractor 50 is at least partially accommodated. The second limiting part 733 has a second sub-groove 713, in which the extension 53 of the magnetic attractor 50 is accommodated. In the first direction X, the inner dimension of the second sub-groove 713 is larger than the inner dimension of the first sub-groove 711. The guide part 735 connects the first limiting part 731 and the second limiting part 733, forming a third sub-groove 715. The third sub-groove 715 connects the first sub-groove 711 and the second sub-groove 713, and together with the first sub-groove 711 and the second sub-groove 713, forms a receiving groove 71. The guide portion 735 is configured to guide the magnetic member 50 into the receiving groove 71 when the magnetic member 50 is inserted into the receiving groove 71, and the guide portion 735 engages with the mating surface 55.
[0070] Specifically, in the first direction X, the main body 51 includes a first side 511 and a second side 513 facing away from each other. Correspondingly, the extension 53 connected to this side also has two side walls facing the electrical connector 30. At this time, a mating surface 55 is provided between the side walls of the corresponding main body 51 and the side walls of the extension 53, that is, the first side 511 and the second side 513 each have a corresponding mating surface 55.
[0071] The first limiting part 731 is a structure in the limiting member 73 used to limit at least a portion of the main body part 51. The spatial structure enclosed by the first limiting part 731 is the first sub-groove 711. At this time, at least a portion of the main body part 51 is accommodated in the first sub-groove 711, and at least a portion of the side wall of the main body part 51 abuts against the inner wall of the first limiting part 731, so that the first limiting part 731 plays a limiting role for this portion of the main body part 51. The second limiting part 733 is a structure in the limiting member 73 used to limit the extension part 53. The spatial structure enclosed by the second limiting part 733 is the second sub-groove 713. At this time, at least a portion of both the extension part 53 and the main body part 51 is accommodated in the second sub-groove 713, and at least a portion of the side wall of the extension part 53 abuts against the inner wall of the second limiting part 733, so that the second limiting part 733 plays a limiting role for the extension part 53. Corresponding to the T-shaped magnetic attractor 50, in the first direction X, the inner dimension of the second sub-slot 713 is the sum of the dimensions of the main body 51 and the dimensions of the two extensions 53, and the inner dimension of the first sub-slot 711 is the same as the dimensions of the main body 51. Therefore, the inner dimension of the second sub-slot 713 is greater than the inner dimension of the first sub-slot 711.
[0072] The guide portion 735 is a structure in the limiting member 73 used to connect the first limiting portion 731 and the second limiting portion 733. At this time, both ends of the guide portion 735 are connected in the first direction X to the end of the first limiting portion 731 near the second limiting portion 733 and the end of the second limiting portion 733 near the first limiting portion 731, respectively, to form a third sub-slot 715. The third sub-slot 715 is sandwiched between the first sub-slot 711 and the second sub-slot 713, and connects the first sub-slot 711 and the second sub-slot 713. The connected spatial structure formed by the first sub-slot 711, the second sub-slot 713, and the third sub-slot 715 is the receiving groove 71. During the process of inserting the magnetic suction member 50 into the receiving groove 71, the guide portion 735 engages with the mating surface 55 to guide the magnetic suction member 50 into the receiving groove 71, making the engagement process between the magnetic suction member 50 and the limiting member 73 simpler and more accurate.
[0073] Therefore, the first limiting part 731, the second limiting part 733, and the guide part 735 cooperate to form a first sub-groove 711, a second sub-groove 713, and a third sub-groove 715, respectively, for accommodating the magnetic suction member 50. The guide part 735 can cooperate with the mating surface 55 of the magnetic suction member 50 to guide the magnetic suction member 50 into the receiving groove 71. At this time, the cooperation process between the magnetic suction member 50 and the limiting part 73 is simpler and more accurate. The magnetic suction member 50 can be installed in the transducer assembly 100 more easily and accurately. The transducer assembly 100 has good structural stability and a long service life. The alignment between the magnetic suction member 50 and the magnetic structure will not change. The alignment accuracy between the electrical connector 30 and the electrical connection mating part 3100 is high. The electrical connection between the electrical connector 30 and the electrical connection mating part 3100 of the charging device 3000 is stable. The charging device 3000 charges the transducer assembly 100 with high efficiency.
[0074] Please refer to Figure 4 and Figure 5 In some embodiments, the size of the barrier 75 is smaller than the height of the limiting member 73 in the thickness direction Z of the transducer 100. Specifically, in the thickness direction Z, the side of the limiting member 70 away from the main body is an open structure, allowing the magnetic member 50 to be installed into the receiving groove 71 through this open structure. When the size of the barrier 75 is smaller than the height of the limiting member 73, the open structure has a structure with different peripheral heights. During the installation of the magnetic member 50 into the receiving groove 71, the magnetic member 50 can initially engage with the receiving groove 71 from at least a portion of the open structure corresponding to the barrier 75 along the positive direction Y1 of the second direction. Further installation is then easier at a certain tilt angle. Therefore, the process of installing the magnetic member 50 into the receiving groove 71 is simple and quick, the production and assembly process of the transducer 100 is simple, and the production cost is low.
[0075] Please refer to Figure 4 and Figure 5In some embodiments, the size of the magnetic chuck 50 is smaller than the height of the limiting member 73 in the thickness direction Z of the transducer assembly 100. Specifically, when the magnetic chuck 50 is housed in the receiving groove 71, the limiting member 73 abuts against at least a portion of the outer sidewall of the magnetic chuck 50 to limit the movement of the magnetic chuck 50 in the forward X1 and reverse X2 directions of the first direction, and in the forward Y1 direction of the second direction. When the size of the magnetic chuck 50 is smaller than the height of the limiting member 73, the magnetic chuck 50 has no portion extending beyond the limiting member 73 in the thickness direction Z. Therefore, the limiting member 73 can abut against the entire sidewall of the magnetic chuck 50 in the thickness direction Z, and the limiting member 73 can better limit the movement of the magnetic chuck 50. In this case, the transducer assembly 100 has better structural stability and a longer service life.
[0076] Please refer to Figure 4 and Figure 5 In some embodiments, the size of the barrier 75 is smaller than the size of the extension 53 in the first direction X. Specifically, the barrier 75 abuts against at least a portion of the sidewall of the magnetic member 50 in the reverse direction Y2 of the second direction. Since the limiting portion has already restricted the movement of the magnetic member 50 in the forward direction X1 and the reverse direction X2 of the first direction, as well as the movement in the forward direction Y1 of the second direction, the barrier 75 can still restrict the movement of the magnetic member 50 in the reverse direction Y2 of the second direction even when the size of the barrier 75 is smaller than the size of the extension 53. In this case, the size of the barrier 75 is smaller, the material cost of the transducer assembly 100 is lower, and the production cost of the transducer assembly 100 is lower.
[0077] Please refer to Figure 4 and Figure 5 In some embodiments, the limiting member 73 and / or the blocking member 75 are provided with a magnetic shielding layer. Specifically, the magnetic shielding layer can be disposed on the inner wall of the limiting member 73 and / or the blocking member 75, or it can be disposed on the outer wall of the limiting member 73 and / or the blocking member 75. The magnetic attractor 50 can form a closed magnetic field in at least a portion of its surrounding area, and the magnetic field strength is stronger the closer to the magnetic attractor 50. Other components such as electrical connectors 30, speakers (not shown), Hall switches (not shown), power supply components 330, etc., may be disposed inside the transducer assembly 100, which will generate small electromagnetic radiation, thereby generating magnetic field interference and affecting the performance of the transducer assembly 100. Therefore, the magnetic shielding layer can prevent magnetic diffusion, avoid the magnetic attractor 50 from affecting the operation of other components, and ensure the magnetic attraction of the magnetic attractor 130, thereby improving the reliability of the adsorption between the earphone 1000 and the charging device 3000. The material of the magnetic shielding layer can be soft iron, silicon steel sheet, permalloy sheet, etc. At this time, the transducer 100 has good safety and stability, and the electrical connector 30 can work safely and stably so that the transducer 100 can work normally.
