Description

Technical Field

[0001] The present application relates to the field of electronic technology, and more particularly, to an interface converter and an electronic system. Background Art

[0002] With the continuous advancement of smartphone technology, users are increasingly demanding higher user experience and security. While traditional plug-in headphone jacks are widely used, they can be inconvenient to plug in and out, prone to loosening, and susceptible to damage. Magnetic jacks are becoming a new trend in mobile phone interface design due to their fast and stable connection. However, these jacks are also relatively expensive to manufacture. Providing an optimal headphone jack solution remains a technical challenge. Summary of the Invention

[0003] The present application provides an interface converter and an electronic system that can provide an optimal interface solution for mobile terminals and magnetic headphones.

[0004] In the first aspect, the present application provides an interface converter for connecting a mobile terminal and a magnetic headset, the interface converter comprising: a plug and a magnetic interface component; the plug comprises an end portion and a tail portion, the end portion being used to insert into the interface of the mobile terminal and connect the mobile terminal, and the tail portion being used to insert into the magnetic interface component and connect the magnetic interface component; the magnetic interface component comprises a first and a second opposite surface, the first surface being provided with a three-level groove, the three-level groove comprising a guide groove, a positioning groove and a locking groove which gradually deepen inward from the first surface, the three-level groove being used to accommodate the tail portion of the plug, the tail portion of the plug being provided with a three-level boss adapted to the three-level groove; the second surface being provided with a first magnetic contact, the first magnetic contact being used to connect to the second magnetic contact of the magnetic headset.

[0005] Through the technical solution of the embodiment of the present application, the interface converter includes a plug and a magnetic interface part. The plug can be adapted and plugged with the mobile terminal. Furthermore, the magnetic interface part can be adapted and connected with the magnetic earphone. The interface converter can provide a solution for connecting the mobile terminal that does not have a magnetic connection method with the magnetic earphone. The first magnetic contact of the magnetic interface part can be connected to the second magnetic contact of the magnetic earphone, and the magnetic contacts are used for mutual connection. Since the magnetic force is smaller than the mechanical force generated when the plug is plugged in, when the magnetic earphone is pulled, the connection between the first magnetic contact of the interface converter and the second magnetic contact of the magnetic earphone is disconnected first, which can reduce the risk of the mobile terminal being pulled due to the magnetic earphone being pulled and the plug connection of the mobile terminal not being disconnected in time. Furthermore, a three-level boss is provided at the tail of the plug, which is adapted and plugged with the three-level groove on the second side of the magnetic interface part, so that the plug and the magnetic interface part can be quickly and stably fastened and plugged. The guide groove can perform preliminary rough positioning of the plug insertion and ensure the correct direction of the plug when inserted; the positioning groove can achieve precise calibration and pre-locking of the plug and the groove; the locking groove can achieve mechanical interlocking and state retention between the plug and the groove, and can provide a stable and tight lock between the plug and the magnetic interface component. The interface converter provided in the embodiment of the present application can improve the reliability of the connection between the mobile terminal and the magnetic headset, and can improve the compatibility of the magnetic headset with more mobile terminals, reducing the application cost of adapting the mobile terminal to the magnetic headset.

[0006] In some embodiments, the positioning slot is provided with an anti-misalignment bevel. By providing the anti-misalignment bevel, the plug can automatically rotate to the correct angle when entering the positioning slot, which can reduce the deflection error to a certain extent.

[0007] In some embodiments, the angle of the foolproof bevel is greater than or equal to 3° and less than or equal to 10°. For example, the angle of the foolproof bevel is 5°.

[0008] Designing the anti-foolproof angle of the positioning groove to be between 3° and 10° can optimize the mechanical properties of the anti-foolproof angle, that is, the three-level boss on the plug can be inserted into the three-level groove in the magnetic interface with less force, and the friction between the three-level boss and the three-level groove can be increased; this angle design meets the usability requirements of consumer electronic products and facilitates the perception of the connection status of the three-level boss and the three-level groove; in addition, conventional molds can be used to produce the anti-foolproof angle, saving manufacturing costs.

[0009] In some embodiments, the locking groove is provided with a spring buckle. For example, the spring buckle is a bistable spring buckle.

[0015] In an embodiment of the present application, a sealing structure is provided on the side wall of the groove, so that the sealing performance of the connection between the second surface and the magnetic earphones can be improved, thereby providing a certain waterproof and dustproof effect for the mobile terminal interface converter and the magnetic earphones that are connected to each other during use.

[0016] In some embodiments, the second surface is provided with a plurality of first magnetic contacts, the plurality of first magnetic contacts including a first left channel output contact, a first right channel output contact, a first ground contact, and a first microphone input contact.

[0017] In the embodiment of the present application, the first left channel output contact can optimize stereo separation, enhance common-mode interference resistance, and output high-fidelity audio, eliminating high-frequency noise interference with the analog signal. The first right channel output contact can improve channel symmetry, maintain stereo balance, expand dynamic range, and suppress contact noise caused by mechanical vibration. The first ground contact can eliminate common ground noise and discharge static electricity to improve the contact safety between the first and second magnetic contacts. It can also reduce the possibility of short circuits through grounding. The first microphone input contact can input high-signal-to-noise ratio voice, providing clear calls and recordings. The coordinated cooperation of these contacts enables high-quality and secure audio input and output.

[0018] In some embodiments, the plurality of first magnetic contacts further include a first detection contact, which is used to connect with a detection contact on the magnetic earphone to detect whether the magnetic interface component and the magnetic earphone are successfully connected.

[0019] In an embodiment of the present application, setting a first detection contact can provide direct basis for whether the mobile terminal interface converter and the magnetic headset are successfully connected, and try to find the problem and achieve reconnection when the connection fails.

[0044] Figure 1The following is a schematic diagram showing the structure of an interface converter according to an embodiment of the present application. The interface converter can be used to connect a mobile terminal and a magnetic earphone.

[0045] like Figure 1 As shown, the interface converter 5 can be connected to the mobile terminal 1 and the magnetic earphone 4. The interface converter 5 includes: a plug 2 and a magnetic interface part 3. The plug 2 includes an end 21 and a tail 22. The end 21 is used to insert into the interface of the mobile terminal 1 and connect to the mobile terminal 1. The tail 22 is used to insert into the magnetic interface part 3 and connect to the magnetic interface part 3. The magnetic interface part 3 includes a first surface 31 and a second surface 32 opposite to each other. The first surface 31 is provided with a three-level groove. The three-level groove includes a guide groove 311, a positioning groove 312 and a locking groove 313 that gradually deepen inward from the first surface 31. The three-level groove is used to accommodate the tail 22 of the plug 2. The tail 22 of the plug 2 is provided with a three-level boss adapted to the three-level groove. The second surface 32 is provided with a first magnetic contact 321. The first magnetic contact 321 is used to connect to the second magnetic contact 41 of the magnetic earphone 4.

[0046] Through the technical solution of the embodiment of the present application, the interface converter 5 includes a plug 2 and a magnetic interface part 3. The plug 2 can be adapted and plugged with the mobile terminal 1. Further, the magnetic interface part 3 can be adapted and connected with the magnetic earphone 4. The interface converter 5 can provide a solution for connecting the mobile terminal 1 that does not have a magnetic connection method with the magnetic earphone. The first magnetic contact 321 of the magnetic interface part 3 can be connected to the second magnetic contact 41 of the magnetic earphone 4, and the magnetic contacts are used for mutual connection. Since the magnetic attraction force is less than the mechanical force generated when the plug 2 is plugged in, when the magnetic earphone 4 is pulled, the connection between the first magnetic contact 321 of the interface converter 5 and the second magnetic contact 41 of the magnetic earphone 4 is disconnected first. This can reduce the risk that the mobile terminal 1 is also pulled due to the magnetic earphone 4 being pulled and the plug 2 at the plug connection of the mobile terminal 1 not being disconnected in time. Furthermore, a three-level boss is provided at the tail 22 of the plug 2, which is adapted to be plugged into the three-level groove on the second side 32 of the magnetic interface part 3, so as to realize the quick and stable fastening and plugging of the plug 2 and the magnetic interface part 3. Among them, the guide groove 311 can perform preliminary rough positioning of the insertion of the plug 2, and make the plug 2 in the correct direction when inserted; the positioning groove 312 can realize the precise calibration and pre-locking of the plug 2 and the groove; the locking groove 313 can realize the mechanical interlocking and state maintenance of the plug 2 and the groove, and can provide a stable and tight locking for the plug 2 and the magnetic interface part 3. The interface converter provided in the embodiment of the present application can improve the reliability of the connection between the mobile terminal and the magnetic earphone, and can improve the adaptability of the magnetic earphone to more mobile terminals, and reduce the application cost of the mobile terminal to adapt the magnetic earphone.

[0047] In some embodiments, the end 21 of the plug 2 cooperates with the interface of the mobile terminal 1. The plug 2 can be a 3.5mm plug, a Type-B plug, a Type-C plug, a Lightning plug, etc., which is not limited in this embodiment of the present application.

[0048] In some embodiments, the tail portion 22 of the plug 2 cooperates with the three-stage groove of the magnetic interface 3. For example, in the three-stage groove, the guide groove 311 can limit the lateral deviation of the tail portion 22 of the plug 2 through the groove body, and use the rectangular or trapezoidal cross-section to guide the plug 2 to slide along a predetermined path, ensuring the correct initial insertion direction.

[0049] Optionally, the guide groove 311 may adopt an asymmetric groove structure, for example, a guide rib is provided on one side to achieve physical foolproofing, so that the tail 22 of the plug 2 can only be inserted in the correct direction to avoid reverse misoperation.

[0050] Optionally, the inner surface of the guide groove 311 may be treated with micron-level texture, so as to make the sliding smooth while reducing the insertion and removal resistance by using a material with a low friction coefficient.

[0051] As a possible embodiment, in the three-level groove, the positioning groove 312 may include an anti-fouling bevel. By setting the anti-fouling bevel, the plug 2 can automatically rotate to the correct angle when entering the positioning groove 312, which can reduce deflection errors to a certain extent.

[0052] Optionally, the positioning groove 312 may be provided with an elastic probe to establish a weak current loop in advance during the physical positioning stage, and confirm the connection status through circuit feedback. Optionally, the edges of the positioning groove 312 may be rounded to reduce stress concentration.

[0053] As a possible implementation, in the three-level groove, a spring clip 3131 can be provided in the locking groove 313 to enhance the tightness of the locking between the plug 2 and the magnetic interface component 3 and improve the durability of the locking groove 313. The spring clip 3131 has a simple structure and can realize convenient and quick locking of the plug 2 and the magnetic interface component 3 through the spring clip 3131.

[0054] Optionally, a silicone damping layer can be provided on the contact surface between the spring clip 3131 and the tail portion 22 of the plug 2 to absorb vibration energy and reduce the possibility of accidental release under external impact. Optionally, a retaining post can be provided at the bottom of the positioning groove 312 to provide a certain degree of mechanical retention in the event of failure of the spring clip 3131.

[0055] Figure 2 FIG. 1 shows a schematic diagram of the structure of the magnetic interface component in the interface converter provided by the embodiment of the present application. Figure 2As shown, in the magnetic interface component 3, the spring clip 3131 located in the locking groove 313 is a bistable spring clip. The bistable spring clip can realize reliable unlocking and locking between the two stable states of connection and disconnection of the first magnetic contact 321 and the second magnetic contact 41, and has the characteristics of labor-saving, high efficiency and durability. For example, when the first magnetic contact 321 and the second magnetic contact 41 are in the connected state, the bistable spring clip can be in a stable locked state, realizing reliable locking between the plug 2 and the magnetic interface component 3. For another example, when the first magnetic contact 321 and the second magnetic contact 41 are in the disconnected state, the bistable spring clip can be in a stable unlocked state, and the plug 2 and the magnetic interface component 3 can be loosened under a small external force.

[0056] A bistable spring latch is a mechanical design capable of switching between two stable states (i.e., locked and unlocked). It achieves self-locking functionality through spring force and geometric deformation, eliminating the need for sustained external force. Its core characteristic is its two energy minimum points (stable positions), making it ideal for applications in consumer electronics, automotive components, medical devices, and other fields.

[0057] In some embodiments, when the plug 2 is fully inserted into the three-level groove of the magnetic interface component 3, the spring clip 3131 can automatically pop into the three-level groove, generate a certain holding force, and prompt through acoustic feedback that the plug 2 and the magnetic interface component 3 are successfully connected.

[0058] Figure 3 FIG. 1 shows an enlarged structural diagram of a three-level groove in an interface converter provided by an embodiment of the present application. Figure 3 As shown, the foolproof angle α of the positioning groove 312 satisfies: 3°≤α≤10°. For example, α=5°.

[0059] The anti-foolproof angle of the positioning groove 312 is designed to be between 3° and 10°, which can optimize the mechanical properties of the anti-foolproof angle, that is, the three-level boss on the plug 2 can be inserted into the three-level groove in the magnetic interface part 3 with less force, and the friction force between the three-level boss and the three-level groove can be increased; this angle design meets the usability requirements of consumer electronic products and facilitates the perception of the connection status of the three-level boss and the three-level groove; in addition, conventional molds can be used to produce the anti-foolproof angle, saving manufacturing costs.

[0060] In the embodiment of this application, the anti-mock angle is designed to be between 3° and 10°, providing a more obvious directional cue, allowing the user to insert the plug naturally without precise alignment, which is ergonomic. In addition, when the anti-mock angle is designed between 3° and 10°, the torque required to rotate the plug 2 to the correct position is approximately 0.02 N·m, which is clearly perceived by the user without any effort.

[0061] In addition, the bevel angle between 3° and 10° is a medium demolding angle in the injection mold, which can make the demolding smooth without increasing the mold wear due to the angle being too small.

[0062] Figure 4 Another structural diagram of the magnetic interface component in the interface converter provided by the embodiment of the present application is shown. Figure 4 As shown, the second surface 32 of the magnetic interface component 3 may include multiple first magnetic contacts 321, for example, a first left channel output contact 3211, a first right channel output contact 3212, a first ground contact 3213 and a first microphone input contact 3214.

[0063] The first left channel contact 3211 optimizes stereo separation, enhances common-mode interference resistance, and outputs high-fidelity audio, eliminating high-frequency noise interference with analog signals. The first right channel contact 3212 enhances channel symmetry, maintains stereo balance, expands dynamic range, and suppresses contact noise caused by mechanical vibration. The first ground contact 3213 eliminates common ground noise and discharges static electricity, improving the contact security between the first magnetic contact 321 and the second magnetic contact 41. Grounding also reduces the possibility of short circuits. The first microphone input contact 3214 inputs voice with a high signal-to-noise ratio, providing clear calls and recordings. The coordinated operation of these contacts ensures high-quality and secure audio input and output.

[0064] In some embodiments, the setting order of the above-mentioned multiple first magnetic contacts 321 can be the first left channel output contact 3211, the first right channel output contact 3212, the first ground contact 3213 and the first microphone input contact 3214 set in a straight line, wherein the setting order can be changed arbitrarily, or can be set according to the position of the vertices of the rectangle, etc., and the embodiment of the present application does not limit this.

[0065] Optionally, the first left channel output contact 3211 or the first right channel output contact 3212 can utilize a composite structure of a beryllium copper alloy base, a hard gold plating layer, and a permalloy magnetic permeability layer to achieve high-fidelity audio transmission. The first ground contact 3213 can utilize a composite structure of a phosphor bronze base, a silver plating layer, and ferrite ceramics to achieve high current carrying and interference resistance. The first microphone input contact 3214 can utilize a titanium copper alloy base with a palladium-nickel plating and a composite neodymium iron boron magnetic powder to capture voice with a high signal-to-noise ratio.

[0066] Figure 5 Another structural diagram of the magnetic interface component in the interface converter provided by the embodiment of the present application is shown. Figure 5As shown, the second surface 32 of the magnetic interface component 3 may include multiple first magnetic contacts 321, for example, it may include a first left channel output contact 3211, a first right channel output contact 3212, a first ground contact 3213, a first microphone input contact 3214 and a first detection contact 3215. The first detection contact 3215 is used to connect with the detection contact on the magnetic earphone to detect whether the magnetic interface component and the magnetic earphone are successfully connected.

[0067] By setting the first detection contact 3215, a direct basis can be provided for determining whether the interface converter 5 and the magnetic earphone 4 are connected successfully or not, and in case of connection failure, a prompt can be obtained as soon as possible and the connection can be reconnected.

[0068] Optionally, the first detection contact 3215 can achieve more reliable connection judgment through a combination of mechanical and magnetic field dual-mode detection, that is, a long and short dual-probe structure can be adopted, the long needle preferentially contacts to trigger pre-connection, and the short needle is fully conductive to confirm effective adsorption; at the same time, a Hall sensor can be integrated to monitor the magnetic field strength, combined with the contact impedance to identify the device type, and dual signal verification can be used to reduce the possibility of false touch and false connection.

[0069] Figure 6 Another structural diagram of the magnetic interface component in the interface converter provided by the embodiment of the present application is shown. Figure 6 As shown, in the magnetic interface component 3 , the second surface 32 may be provided with a groove 322 , and the first magnetic contact 321 is provided on the bottom wall of the groove 322 .

[0070] Providing a groove 322 on the second surface 32 and arranging the first magnetic contact 321 on the bottom wall of the groove 322 can provide a certain degree of protection for the first magnetic contact 321, reduce the wear and tear experienced by the first magnetic contact during use of the interface converter, and extend the service life of the first magnetic contact.

[0071] In some alternative embodiments, the first magnetic contacts 321 may also be disposed on the sidewalls of the groove 322 . Alternatively, a portion of the plurality of first magnetic contacts 321 may be disposed on the bottom wall of the groove 322 , and another portion may be disposed on the sidewalls of the groove 322 .

[0072] Optionally, the side wall and the bottom wall of the groove 322 may be arranged at right angles or at rounded angles, which is not limited in the embodiment of the present application.

Figure 7 As shown, in the magnetic interface component 3 , the second surface 32 thereof may be provided with a sealing structure 323 , and the sealing structure 323 may be provided on the side wall of the groove 322 .

[0074] By setting a sealing structure 323 on the side wall of the groove 322, the sealing performance of the connection between the second surface 32 and the magnetic earphone 4 can be improved, providing a certain waterproof and dustproof effect for the interface converter 5 and the magnetic earphone 4 connected to each other during use.

[0075] Optionally, the material of the sealing structure 323 can be natural rubber, silicone rubber, ethylene propylene rubber, nitrile rubber, fluorinated rubber, etc., which is not limited in the embodiment of the present application.

[0076] Figure 8 and Figure 9 Two other structural schematic diagrams of the magnetic interface member in the interface converter provided in the embodiment of the present application are respectively shown. In the above embodiment, the second surface 32 of the magnetic interface member 3 can be rectangular. In other embodiments, such as Figure 8 and Figure 9 As shown, the second surface 32 of the magnetic interface component 3 may also be square or triangular.

[0077] Designing the second surface 32 to be square or triangular can meet the shape requirements of the magnetic interface component 3 in different storage environments and usage environments.

[0078] Optionally, the second surface 32 may also be a circle, a rounded rectangle, a trapezoid, an ellipse, etc., which is not limited in the embodiment of the present application.

[0079] An embodiment of the present application also provides an electronic system, which may include the interface converter 5, the mobile terminal 1, and the magnetic earphone 4 in any of the above embodiments.

[0080] To adapt to the interface converter 5, as an example, Figure 10 A structural schematic diagram of the magnetic earphones provided in an embodiment of the present application is shown.

[0081] like Figure 10 As shown, the magnetic earphones 4 may include a left channel output terminal 42, a right channel output terminal 43, a ground terminal 44, a microphone input terminal 45 and a magnetic attraction connection part 46. A plurality of second magnetic contacts 41 may be provided on the magnetic attraction connection part 46. For example, the plurality of second magnetic contacts 41 include a second left channel output contact 411, a second right channel output contact 412, a second ground contact 413 and a second microphone input contact 414; wherein, the left channel output terminal 42 is connected to the second left channel output contact 411, the right channel output terminal 43 is connected to the second right channel output contact 412, the ground terminal 44 is connected to the second ground contact 413, and the microphone input terminal 45 is connected to the second microphone input contact 414.

[0082] The left channel output terminal 42 and the second left channel output contact 411 optimize stereo separation, enhance common-mode interference resistance, and output high-fidelity audio, eliminating high-frequency noise interference with analog signals. The right channel output terminal 43 and the second right channel output contact 412 enhance channel symmetry, maintain stereo balance, expand dynamic range, and suppress contact noise caused by mechanical vibration.
