Description

Technical Field

[0001] The present invention relates to the technical field of wireless earphones, and in particular to a wireless earphone assembly with a detachable magnetic ear cap and a charging box thereof. Background Art

[0002] OWS earphones are an open-type, non-in-ear wireless Bluetooth earphones. They hang on the ears like earrings, without invading the ear canal or blocking the ears. Based on TWS earphones, they are equipped with air directional sound transmission technology. Through chips and special physical structures, the sound is only transmitted to the wearer's ears, rather than spreading around like speakers, so it has good privacy.

[0003] Existing OWS headphones generally include a headphone shell, a circuit board, a power module, and a sound module. The headphone shell is curved and shaped to hang on the user's ear, while the sound module is aimed at the user's ear for directional sound transmission. However, although open-type headphones have the advantages of not invading the ear canal and not blocking the ear, compared with in-ear headphones, their sound quality is also poorer due to the loss of sound transmission, especially when the user is in an outdoor environment. Due to the large noise outdoors, the sound quality of open-type headphones will be further deteriorated.

[0004] In the prior art, there are also headphone products that combine in-ear headphones and open-ear headphones, that is, detachable ear caps are connected to open-ear headphones, and users can decide whether to use the ear caps according to their own needs, thereby switching between in-ear and open-ear headphones. However, since the sound outlet of the open-ear headphones is still slightly away from the ear canal, and in order to ensure that the ear caps can be smoothly inserted into the ear canal, the ear caps need to have a certain thickness. However, if the thickness of the ear caps is long enough, although it can ensure that the ear caps are fully inserted into the ear canal, it will also cause a larger storage space for the ear caps, which will be a considerable challenge for the already compact headphone charging box. To this end, we propose a wireless headphone assembly with detachable magnetic ear caps and a charging box thereof to well solve the above-mentioned drawbacks. Summary of the invention

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figure 1 - Fig.11 A wireless earphone assembly with a detachable magnetic ear cap includes an earphone body 100 and a magnetic ear cap 200, wherein the earphone body 100 includes a main shell 101, an ear hook crank 102, a circuit board 103, a sound module 104 and a power module, the ear hook crank 102 is a hollow curved tube structure, one end of the ear hook crank 102 is connected to the main shell 101, and the ear hook crank 102 and the interior of the main shell 101 are communicated, the circuit board 103 is arranged in the main shell 101, the power module is arranged in the ear hook crank 102, and the power module and the circuit board 103 are connected through a wire.

[0038] Furthermore, an accommodating notch is provided at one end of the main shell 101, and a sub-shell 300 is movably provided in the accommodating notch. The sub-shell 300 can slide along the thickness direction of the main shell 101, and the sound module 104 is arranged inside the sub-shell 300, and the sound module 104 is connected to the circuit board 103 through a wire; when the sub-shell 300 and the main shell 101 are in contact, the surface of the sub-shell 300 is flush with the surface of the main shell 101; when there is a gap between the sub-shell 300 and the main shell 101, the sub-shell 300 protrudes from the surface of the main shell 101; it should be noted that a wiring hole 105 for the wire to pass through is provided on the inner wall of the accommodating notch, and the wire connecting the sound module 104 and the circuit board 103 passes through the wiring hole 105.

[0039] On the other hand, one end of the magnetic ear cap 200 has a first magnetic ring 201, and the interior of the secondary housing 300 is provided with a second magnetic ring 301. When the first magnetic ring 201 and the second magnetic ring 301 attract and fit each other, the magnetic ear cap 200 is installed on the secondary housing 300. That is, the magnetic ear cap 200 is connected to the secondary housing 300 by magnetic attraction. When the magnetic ear cap 200 is removed, the product can be used as an external earphone, and when the magnetic ear cap 200 is installed, the product can be used as an in-ear earphone.

[0040] The following describes the connection method between the auxiliary housing 300 and the main housing 101:

[0041] The secondary housing 300 is a circular hollow structure, the receiving notch matches the shape of the secondary housing 300, and the inner wall of the receiving notch is also provided with a through hole 106 communicating with the interior of the main housing 101, and an elastic component 400 is provided in the through hole 106, and the secondary housing 300 is elastically connected to the main housing 101 through the elastic component 400. The elastic component 400 includes a telescopic sleeve 401, a return spring 402 and a sliding part 403, the telescopic sleeve 401 is inserted into the through hole 106, the two ends of the telescopic sleeve 401 are respectively connected to the inner wall of the main housing 101 and the sliding part 403, the return spring 402 is located in the telescopic sleeve 401, the two ends of the return spring 402 are respectively abutted against the inner wall of the main housing 101 and the sliding part 403, and the sliding part 403 is slidably matched with the secondary housing 300. It should be noted that the telescopic sleeve 401 is composed of two short tubes that are slidably connected to each other. Therefore, the sliding part 403 is equivalent to being elastically connected to the main shell 101, and the sub-shell 300 and the sliding part 403 are slidably matched, that is, the sub-shell 300 and the main shell 101 can move along the axial direction of the telescopic sleeve 401, and can also be displaced along the sliding direction of the sliding part 403.

[0042] In addition, two insertion holes 107 are provided on the side wall of the receiving notch, and an insertion portion 302 is provided on the outer surface of the secondary housing 300 and at a position directly opposite to the insertion holes 107. When the insertion portion 302 is inserted into one of the insertion holes 107, the secondary housing 300 fits against the inner wall of the receiving notch, and when the insertion portion 302 is inserted into the other insertion hole 107, a gap is formed between the secondary housing 300 and the inner wall of the receiving notch. Specifically, the insertion portion 302 is composed of two relatively distributed plug plates, which are an integrally formed structure with the secondary housing 300, and the opposite back surfaces of the two plug plates are protrudingly formed with bulges 303. When the insertion portion 302 is inserted into the plug hole 107, the bulge 303 passes through the plug hole 107 and extends into the main housing 101, and the plug plate fits against the inner surface of the plug hole 107; therefore, the bulge 303 has the function of preventing the secondary housing 300 from falling off, which is conducive to improving the stability of the secondary housing 300.

[0043] In some embodiments of the present application, a telescopic opening 304 is provided on the outer surface of the secondary housing 300, and the telescopic opening 304 is circular. A telescopic portion 305 is movably provided in the telescopic opening 304, and the telescopic portion 305 is an annular structure. A sound outlet cover 306 is fixedly embedded on the outer surface of the telescopic portion 305, and the sound module 104 is arranged on the inner side of the telescopic portion 305, and the second magnetic ring 301 is fixedly embedded on the outer surface of the telescopic portion 305. The telescopic portion 305 is elastically connected to the inner wall of the secondary housing 300 by a push spring 307. When the push spring 307 is not subjected to the external force of the system, the telescopic portion 305 shrinks to the inner side of the telescopic opening 304 and is lower than the outer surface of the secondary housing 300. Specifically, the sound module 104 is located on the inner side of the sound outlet cover 306, and the sound outlet cover 306 is a porous plate structure made of plastic material, and its function is to prevent large particles of impurities from entering the secondary housing 300.

[0044] Furthermore, a guide groove 308 is formed on the inner ring wall of the telescopic opening 304, and a guide rail 309 is formed on the outer surface of the telescopic portion 305. The guide groove 308 is consistent with the telescopic direction of the elastic component 400, and the guide rail 309 is movably embedded in the guide groove 308, so that the telescopic portion 305 can slide along the length direction of the guide groove 308. A push column 108 is formed on the inner wall of the accommodating notch, and a through hole 310 for the push column 108 to pass through is formed on the side wall of the auxiliary housing 300. When the insertion portion 302 is inserted into a socket 107 close to the inner side of the main shell 101, the sub-shell 300 fits against the inner wall of the accommodating notch, and the push column 108 abuts against the telescopic portion 305. At this time, the outer surface of the telescopic portion 305 is flush with the outer surface of the sub-shell 300. When the insertion portion 302 is inserted into another socket 107, a gap is formed between the sub-shell 300 and the inner wall of the accommodating notch, and at this time, the push column 108 does not contact the telescopic portion 305. The telescopic portion 305 is lower than the outer surface of the sub-shell 300, and the height difference between the outer surface of the telescopic portion 305 and the sub-shell 300 is smaller than the gap between the sub-shell 300 and the inner wall of the accommodating notch.

[0045] To sum up, in the specific application process of this embodiment, when the user needs to use an external headset, the insertion part 302 is inserted into a jack 107 close to the inner side of the main shell 101. At this time, the sub-shell 300 and the main shell 101 fit each other, and the sub-shell 300 is flush with the outer surface of the main shell 101. The user only needs to hang the ear hook crank 102 on the ear to use it.

[0046] When the user needs to use the in-ear headphones, the user first takes off the headphones, then holds the main housing 101 with his hand, and rubs the secondary housing 300 with his thumb to pull the insertion portion 302 out of the jack 107. Then, under the thrust of the return spring 402, the secondary housing 300 automatically pops outward and forms a certain gap with the inner wall of the accommodating notch. At this time, the secondary housing 300 is pushed toward one side of the jack 107 to insert the insertion portion 302 into the other jack 107, so that the position of the secondary housing 300 is fixed. It is worth mentioning that when the secondary housing 300 pops out, due to the loss of the abutment of the push column 108, the telescopic portion 305 will shrink inward to the telescopic opening 304 and be lower than the outer surface of the secondary housing 300 under the action of the push spring 307. At this time, the user can embed the magnetic ear cap 200 into the telescopic opening 304. Under the attraction of the two magnetic rings and the restriction of the telescopic opening 304, the stability of the magnetic ear cap 200 can be ensured, and the magnetic ear cap 200 is prevented from being misaligned with the first magnetic ring 201 and the second magnetic ring 301 due to the lateral force on the magnetic ear cap 200, so that the mutual attraction force of the magnetic rings is weakened. Therefore, the design of embedding the magnetic ear cap 200 into the telescopic opening 304 helps to improve the adsorption stability of the magnetic ear cap 200.

[0047] In addition, in this embodiment, by rubbing the sub-shell 300, the insertion portion 302 is inserted into the corresponding jack 107, so that the in-ear earphone and the open earphone can be switched, which is simple to operate and convenient to use. Secondly, when the insertion portion 302 is inserted into a jack 107 near the outside, a certain gap is formed between the sub-shell 300 and the inner wall of the receiving notch, that is, the sub-shell 300 will extend toward the side close to the user's ear canal, which helps the magnetic ear cap 200 to be fully inserted into the ear canal and prevent the ear cap from falling off easily.

[0048] Embodiment 2: This embodiment of the present application provides a charging box, which is applicable to the wireless headset assembly in Embodiment 1, including a box body 500 and a box cover 501, such as Fig.12 As shown, the box cover 501 is hingedly arranged on one side of the top of the box body 500, an earphone storage slot 502 is provided on the inner side of the box body 500, two ear cap storage slots 503 are provided on the inner surface of the box cover 501, and adsorption magnetic rings are provided inside the two ear cap storage slots 503.

[0049] During the use of this embodiment, when the earphones need to be stored in the earphone box, the magnetic ear caps 200 and the earphone body 100 are first disassembled, and then the two magnetic ear caps 200 are respectively inserted into the two ear cap storage slots 503, and then the two earphone bodies 100 are symmetrically placed in the earphone storage slots 502, and then the box cover 501 is closed to complete the storage of the earphones.
