[0032] Reference below Figure 1-Figure 4 The magnetic attraction structure of an audio receiver according to an embodiment of the utility model is described.
[0033] like Figure 1-Figure 4 As shown, the magnetic structure of the audio receiver includes a shell 100 of the audio receiver and a connector 200 connected to the shell 100, and the audio receiver is connected to recording devices of different interfaces through the connector 200. Specifically, a connection terminal 110 is provided on the surface of the shell 100, and a plurality of metal contacts 111 are provided in the connection terminal 110. The connector 200 is magnetically connected to the connection terminal 110, and a connecting portion 210 that is engaged and connected to the connection terminal 110 is provided on the side of the connector 200. The connection portion 210 is provided with a plurality of metal contacts 111, and the positions of the metal contacts 111 in the connection portion 210 and the connection terminal 110 correspond one to one. In this embodiment, the number of metal contacts 111 of the connection portion 210 and the connection terminal 110 is equal, and each metal contact 111 corresponds to a group of pins of the connection terminal 110 and the connection portion 210.
[0034] Among them, the connector 200 is provided with a connecting magnetic member 220, and the housing 100 is provided with an aligning magnetic member 120, and the connecting magnetic member 220 and the aligning magnetic member 120 have opposite magnetic poles. The connecting magnetic member 220 and the aligning magnetic member 120 are magnetically connected based on the principle that like poles repel each other and opposite poles attract each other, and the metal contacts 111 of the connecting end 110 and the connecting part 210 are brought into contact through the magnetic force. When the connecting part 210 is close to the connecting end 110, the aligning magnetic member 120 is magnetically connected to the connecting magnetic member 220, and the metal contacts 111 in the connecting end 110 are connected to the metal contacts 111 in the connecting part 210. The connector 200 is then plugged into the recording device, so that the audio receiver can achieve data transmission with the recording device through the connector 200.
[0035] Compared with the existing sliding card connection structure, this embodiment does not need to open a card slot on the surface of the shell 100. When the connecting end 110 and the connecting part 210 are engaged, the shell 100 of the audio receiver has a more complete and more beautiful appearance, and can improve the sealing between the shell 100 and the connector 200, and improve the dustproof and waterproof performance of the connection structure. When two magnets with opposite magnetic poles are close to each other, they will be attracted to each other by the magnetic force, and the effect of automatic positioning and connection can be achieved. Users can operate quickly in dark environments or blind operations, and the connection is more convenient.
[0036] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the connecting magnetic member 220 includes a first magnetic member 221 and a second magnetic member 222 disposed on both sides of the connecting portion 210 , and the magnetic poles of the first magnetic member 221 and the second magnetic member 222 are opposite.
[0037] Specifically, the first magnetic component 221 and the second magnetic component 222 are respectively arranged on both sides of the connecting part 210, so that both ends of the connecting part 210 and the connecting end 110 are magnetically connected when they are engaged with each other, so that the connection between the connecting part 210 and the connecting end 110 is tighter and the magnetic attraction is more balanced, ensuring that the metal contacts 111 of the two are tightly connected, thereby improving the connection stability.
[0038] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the alignment magnetic member 120 includes a third magnetic member 121 and a fourth magnetic member 122, the third magnetic member 121 and the fourth magnetic member 122 have opposite magnetic poles, the first magnetic member 221 and the third magnetic member 121 have the same magnetic poles, and the second magnetic member 222 and the fourth magnetic member 122 have the same magnetic poles.
[0039] Specifically, when the connection end 110 and the connection part 210 are close to each other, the first magnetic member 221 and the fourth magnetic member 122 have opposite magnetic poles and are magnetically attracted to each other, and the second magnetic member 222 and the third magnetic member 121 have opposite magnetic poles and are magnetically attracted to each other. When the connection end 110 and the connection part 210 are reversely connected, the first magnetic member 221 and the third magnetic member 121 have the same magnetic poles and repel each other, and the second magnetic member 222 and the fourth magnetic member 122 have the same magnetic poles and repel each other, thereby playing a fool-proof role and effectively avoiding the connection end 110 and the connection part 210 from being connected incorrectly.
[0040] In some embodiments of the present invention, Figure 4 As shown, the housing 100 is provided with magnet mounting grooves 130 on both sides of the connecting end 110 . The magnet mounting grooves 130 are located inside the housing 100 , and the third magnetic member 121 and the fourth magnetic member 122 are installed in the magnet mounting grooves 130 .
[0041] Specifically, the magnet mounting groove 130 is slotted inside the shell 100 , and the magnet mounting groove 130 cannot be observed outside the shell 100 , which can prevent the magnetic component from falling off and improve the appearance integrity of the shell 100 .
[0042] In some embodiments of the present invention, the end of the connector 200 adopts any one of a Type-C structure, a Lightning structure, and a 3.5mm audio structure.
[0043] Specifically, mainstream mobile devices and dedicated recording devices usually cover the above three connector 200 structures. Users can replace the corresponding connector 200 according to their own needs to improve the applicability of the audio receiver.
[0044] It should be understood that the use of Type-C structure, Lightning structure and 3.5mm audio structure by connector 200 is not the only implementation method. In some other embodiments, Micro-USB and Mini-USB structures can also be used to support earlier recording devices. The utility model does not elaborate on the types of end structures of connector 200. It should be understood that the flexible change of the end structure types of connector 200 without departing from the basic concept of the utility model should be regarded as within the protection scope defined by the utility model.
[0045] In some embodiments of the present invention, a sealing ring (not shown in the drawings) is provided around the connection end 110 and the connection part 210. When the connection end 110 and the connection part 210 are magnetically engaged, the space connected by the metal contact 111 is in a sealed state. The sealing ring can prevent dust from accumulating in the connection gap, play a role in waterproofing and dustproofing, and effectively prevent the metal contact 111 from being corroded.
[0046] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the periphery of the connection end 110 and the connection part 210 is rounded, which improves the smoothness of the connection between the connection end 110 and the connection part 210 and makes it easier to clean the corners.
[0047] The magnetic attraction structure of the audio receiver of the utility model has two embodiments, and the accompanying drawings show the first embodiment, specifically:
[0048] In the first embodiment, the connection end 110 is recessed into the housing 100 , and the connection portion 210 is protruded on the surface of the connector 200 . The recessed depth of the connection end 110 is equal to the protruding height of the connection portion 210 .
[0049] In the second embodiment, the connection end 110 is convexly disposed on the surface of the housing 100 , and the connection portion 210 is concavely disposed toward the inside of the connector 200 . The concave depth of the connection portion 210 is equal to the protruding height of the connection end 110 .

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
