[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.
[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0028] Example 1:
[0029] Please see Figure 1 and Figure 2 The present invention discloses an audio adapter 100, comprising a housing 1 and a PCBA board 3 disposed within the housing 1. The PCBA board 3 is provided with a Type-C male connector 4, a magnetic male connector 5, and a 3.5mm audio interface 6. The housing 1 is divided into a handle portion 13, a bending portion 14, and a connecting portion 15 along its length. The magnetic male connector 5 is disposed on one side of the handle portion 13, and the 3.5mm audio interface 6 is disposed on the end face of the connecting portion 15. The magnetic male connector 5 includes a plurality of Pogo-pin male terminals 51 and magnetic components 52. The Pogo-pin male terminals 51 are used for electrical connection with an external charging device, and the magnetic components 52 are used for magnetic engagement.
[0030] Specifically, the housing 1 of the audio adapter 100 is divided into three parts along its length: a handle 13, a bending part 14, and a connecting part 15. When the audio adapter 100 is plugged into the electronic device 200, the curvature of the handle 13 conforms to the natural bending angle of the human hand, which makes it convenient for the user to hold it stably for a long time. The setting of the magnetic male connector 5 is optional but not limited to. Its position design matches the natural range of motion of the fingers when holding, which makes it convenient for the user to quickly plug and unplug external charging devices with one hand.
[0031] The PCBA board 3 is installed inside the housing 1. The PCBA board 3 controls the signal transmission function of each connector. Three interfaces are soldered on the PCBA board 3, all of which extend out of the housing 1 to facilitate the insertion and mating of external devices. The three interfaces are a Type-C male connector 4, a charging interface, and a 3.5mm audio interface 6. The charging interface is designed as a magnetic interface, specifically a magnetic male connector 5, which is used to magnetically engage with external charging devices, thereby improving the charging connection efficiency and allowing users to easily plug and unplug the device at any time. The magnetic male connector 5 has several Pogo-pin male terminals 51 and magnetic components 52. The magnetic components 52 are used to attract external charging devices. The magnetic male connector 5 adopts the Pogo-pin magnetic engagement electrical connection method. Its elastic structure can generate continuous contact pressure, making it less likely to disconnect the charging function in a vibration environment. It can also avoid problems such as loosening and wear of the charging interface due to repeated plugging and unplugging, effectively extending the service life of the audio adapter 100.
[0032] In addition, external charging devices achieve automatic alignment via magnetic guidance, allowing users to quickly complete the charging connection through magnetic sensing, thus improving ease of use. The magnetic charging interface automatically separates without damaging the internal circuitry; if excessive external force is applied, the magnetic contact breaks, preventing damage to the wiring harness.
[0033] In this embodiment, when the audio adapter 100 is in use, the Type-C male connector 4 on the PCBA board 3 is inserted into the electronic device 200. Data transmission of the adapter is realized through this interface. The 3.5mm audio interface 6 is connected to the headphones 300. The audio signal transmitted by the electronic device 200 is transmitted from the PCBA board 3 to the headphones 300 through the 3.5mm audio interface 6. The external charging device is connected to the magnetic male connector 5 of the audio adapter 100 through magnetic attraction. It supplies power to the PCBA board 3 through the Pogo-pin male terminal, and then the PCBA board 3 charges and transmits power to the electronic device 200 through the Type-C male connector 4.
[0034] Example 2:
[0035] This embodiment is a further structural optimization of the audio adapter 100 of this utility model. Please refer to [link / reference]. Figure 3 and combined Figure 1 .
[0036] In some embodiments, the housing 1 includes an upper housing 11 and a lower housing 12 whose edges are sealed and fastened together, and the upper housing 11 is detachably mounted on the lower housing 12.
[0037] Specifically, the housing 1 adopts a split structure, and is fixed by fastening the upper and lower housings 12. Multiple limiting structures are provided on the lower housing 12 to fix the PCBA board 3 and prevent it from shifting during use and affecting normal use. Each interface is provided with the connection point between the upper housing 11 and the lower housing 12.
[0038] In some embodiments, the outer side of the lower housing 12 is provided with a concave surface 121 of a certain arc, and the magnetic male seat 5 is disposed in the concave surface 121.
[0039] Specifically, the connection between the external charging device and the magnetic male seat 5 has a convex structure. The concave surface 121 on the outer side of the lower housing 12 contacts the convex surface 211 of the external charging device. The convex surface 211 adopts a complementary arc design. When the two are close, the convex surface 211 will automatically embed into the concave surface 121 due to magnetic guidance, forming a mechanical limit and improving the docking efficiency.
[0040] In some embodiments, the concave surface 121 is provided on the lower housing 12 at a position away from the edge of the 3.5mm audio interface 6.
[0041] Specifically, the concave surface 121 and the 3.5mm audio interface 6 are located on the two sides of the lower housing 12, respectively. When the audio adapter 100 connects to both audio devices and external charging devices at the same time, the two devices will not squeeze each other due to insufficient space, thus avoiding interface interference.
[0042] In some embodiments, the concave surface 121 is provided with a protruding ridge 212 or a groove 123 for positioning and limiting during magnetic attraction.
[0043] Specifically, an anti-detachment structure is provided on the magnetic docking. After the concave surface 121 and the convex surface 211 are attached, the contact surface forms a ring support structure. A convex ridge 212 and a groove 123 are respectively provided at the connection. The convex ridge 212 and the groove 123 are inserted and matched to prevent reverse connection and provide a certain degree of stability, which can prevent the external charging device from becoming loose during the charging process.
[0044] In some embodiments, a U-shaped groove 122 is provided on the inner side of the lower housing 12, a magnetic male seat 5 is provided on the inner side of the U-shaped groove 122, a magnetic member 52 is provided in the U-shaped groove 122, and a Pogo-pin male end 51 extends out a concave surface 121 in the direction of the lower housing 12.
[0045] Specifically, the lower housing 12 has a U-shaped groove 122 near the concave surface 121. The U-shaped groove 122 is located inside the lower housing 12 and is used to place the magnetic attractor 52, restrict the movement of the magnetic attractor 52 and play a protective role. The U-shaped groove 122 is arranged around the magnetic male seat 5, and the magnetic male seat 5 is located inside the U-shaped groove 122, which can also protect the Pogo-pin male end 51 on the magnetic male seat 5 and play a role in preventing bending.
[0046] In this embodiment, the housing 1 of the audio adapter 100 adopts a split structure, making assembly and maintenance more convenient. The housing 1 has a limiting and anti-displacement structure to ensure the stability of internal components. The magnetic male connector 5 magnetically engages with the external charging device, and the concave surface 121 on the outer side of the lower housing guides the connection with the convex surface 211 of the external charging device. Furthermore, a raised ridge 212 and a groove 123 are provided on the magnetic connection surface to prevent reverse connection and enhance connection stability, making it less prone to loosening or disconnection during charging. Additionally, the elastic Pogo-pin male terminal 51 provides electrical connection and, in conjunction with the magnetic component 52, allows it to engage with the female terminal of the external charging device, ensuring stable charging even in vibration environments.
[0047] Example 3:
[0048] This embodiment, based on the above embodiments, provides an audio adapter component. Please refer to [link to previous embodiment]. Figures 1 to 4 .
[0049] In some embodiments, an audio adapter assembly includes an audio adapter 100 and a magnetic charging head 2. The magnetic charging head 2 is provided with a magnetic female connector 21 that magnetically engages with a magnetic male connector 5. The Pogo-pin male terminal 51 of the magnetic male connector 5 is electrically connected to the magnetic female connector 21.
[0050] Specifically, the magnetic charging head 2 is an external charging device for the audio adapter 100. It is electrically connected to the magnetic male connector 5 by magnetic attraction through the magnetic female connector 21. The current is transmitted to the PCBA board 3 through the Pogo-pin male terminal 51 of the magnetic male connector 5, and then transmitted to the electronic device 200 through the Type-C male connector 4 of the PCBA board 3.
[0051] In some embodiments, the magnetic insertion and removal direction of the magnetic male connector 5 is perpendicular to the plane on which the PCBA board 3 is located.
[0052] Specifically, the magnetic male connector 5 on the PCBA board 3 extends perpendicularly outward from the housing 1, and the magnetic charging head 2 achieves charging engagement through magnetic insertion and removal. This vertical insertion and removal method is suitable for narrow-bezel devices, and when the audio adapter 100 is held, the magnetic charging head 2 can be easily accessed by hand, making it less likely to fall off. In addition, the 3.5mm audio interface 6 is perpendicular to the insertion direction of the Type-C male interface 4. This design not only avoids audio cable interference but also makes it easier for users to hold and plug in audio devices.
[0053] In some embodiments, the PCBA board 3 is provided with a power supply detection module 31, an enable control module 32, a switch module 33, and a PD processor 34. The power supply detection module 31 is connected to the enable control module 32 and the switch module 33 respectively. The power supply detection module 31 is used to detect the insertion status of the 3.5mm audio interface 6. The enable control module 32 is connected to the switch module 33 and the PD processor 34 respectively. The enable control module 32 is used to control the PD processor 34 to switch the fast charging mode. The switch module 33 is used to control the conduction status of the externally connected current to the Type-C male interface 4 and the 3.5mm audio interface 6.
[0054] Specifically, the power supply detection module 31 can identify the power supply based on the insertion and connection status of the Type-C male connector 4 and the magnetic charging head 2. The PD processor 34 identifies the power supply protocol and sends an enable signal to the enable control module 32. The PD processor 34 can determine the connection status of the magnetic charging head 2, generate an enable signal, and transmit it to the enable control module 32. The enable control module 32 uses the enable signal to control the switch module 33, allowing the input current of the magnetic charging head 2 to be input to the Type-C male connector 4 and the 3.5mm audio interface 6. It also controls the PD processor 34 to switch to fast charging mode, allowing a large current to flow through the Type-C male connector 4 to the electronic device 200. The PD processor 34 establishes a data transmission path between the electronic device 200 and the headphones 300, while maintaining the charging path of the magnetic charging head 2 to the system, enabling the electronic device 200 to charge while simultaneously using the headphones 300.
[0055] Furthermore, PCBA board 3 is also provided with a voltage regulator module 35, which is connected to the power supply detection module 31 and the PD processor 34 respectively, and is used to provide a stable DC power supply to the PD processor 34.
[0056] In this embodiment, the housing 1 has an asymmetrical shape along its length. The thicker end of the audio adapter 100 is designed for gripping, and the magnetic connector 21 is located on the palm's contact surface. The magnetic connector 21 corresponds to a position naturally accessible to the thumb, allowing for efficient insertion and removal with one hand. The 3.5mm audio interface 6 is located on the side near the narrow end of the housing 1, preventing the charging cable and audio cable from crossing and tangling within the hand's operating space. Understandably, when the electronic device 200 is held horizontally for playing games or watching videos, the 3.5mm audio interface 6 faces away from the grip, allowing the audio cable to extend naturally without interfering with the hand's grip space.
