[0045] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0046] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0048] In one embodiment, referring to the accompanying drawings Figures 1 to 4 A foldable Bluetooth headset is described, which can hang the headset body 100 and the headset holder 300 on the human ear through the clamping assembly 200, and can be adapted to ears of different shapes by adjusting the opening and closing angles of the first clamping arm 210 and the second clamping arm 220, the opening and closing angles of the first clamping arm 210 and the headset body 100, and the opening and closing angles of the second clamping arm 220 and the headset holder 300, so as to enhance the wearing experience of consumers and increase their enthusiasm for wearing. At the same time, the foldable Bluetooth headset is easy for consumers to store, and the headset in the stored state has a compact structure, beautiful appearance, and is easy to carry.

[0049] In this embodiment, the foldable Bluetooth headset includes an earphone body 100, a clamping assembly 200, an earphone body 100 and an earphone holder 300, wherein the clamping assembly 200 includes two L-shaped clamping arms, namely a first clamping arm 210 and a second clamping arm 220, one end of the first clamping arm 210 is hinged to one end of the second clamping arm 220, and accordingly, the earphone body 100 is hinged to one end of the first clamping arm 210 away from the second clamping arm 220, and the earphone holder 300 is hinged to one end of the second clamping arm 220 away from the first clamping arm 210.

[0050] It is worth noting that the holding component 200 has a storage state and a use state. When in the storage state, the first clamping arm 210 and the second clamping arm 220 are located on the same straight line and together form a storage space. It is understandable that the clamping arm is L-shaped, and the first clamping arm 210 and the second clamping arm 220 are located on the same straight line, so that the two clamping arms form a semi-enclosed structure. Consumers can push the earphone body 100 to rotate around the first clamping arm 210, and the earphone tray 300 to rotate around the second clamping arm 220, thereby storing the earphone body 100 and the earphone tray 300 in the storage space.

[0051] Accordingly, when the foldable Bluetooth headset is in use, the first clamping arm 210 and the second clamping arm 220 are not located in the same straight line. Consumers can clamp the first clamping arm 210 and the second clamping arm 220 on both sides of the ears, and adjust the opening and closing angle according to the thickness of the auricle, and adjust the opening and closing angle of the first clamping arm 210 and the headset body 100, and the opening and closing angle of the second clamping arm 220 and the headset holder 300, so that the foldable Bluetooth headset fits the consumer's ears better.

[0052] In actual use, consumers can use the clamping assembly 200 to clamp their own auricle to achieve the foldable Bluetooth headset worn on the ear, which is comfortable to wear. It is understandable that when consumers do not need to wear the foldable Bluetooth headset, the headset body 100 and the headset holder 300 are stored in the accommodation space formed by the first clamping arm 210 and the second clamping arm 220. At this time, the foldable Bluetooth headset is similar to a square column, which makes the foldable Bluetooth headset compact and easy for consumers to carry. Moreover, the foldable Bluetooth headset is suitable for the ears of different consumers. Consumers can adjust the opening and closing angle according to their own auricle structure, and the adjustment range is more extensive and flexible. Compared with existing headsets on the market, the foldable Bluetooth headset can improve consumers' wearing experience and enthusiasm and meet the use needs of different groups of people.

[0053] In one embodiment, referring to the accompanying drawings Figures 1 to 4The first clamping arm 210 and the second clamping arm 220 are rotationally connected via the damping shaft 500. Accordingly, the first clamping arm 210 and the earphone body 100 are rotationally connected via the damping shaft 500, and the second clamping arm 220 and the earphone holder 300 are rotationally connected via the damping shaft 500.

[0054] Further, a first concave portion 211 is provided at one end of the first clamping arm 210, and correspondingly, a first convex portion 221 is provided at one end of the second clamping arm 220, and the first convex portion 221 and the first concave portion 211 can be engaged with each other. Specifically, a damping shaft 500 is provided on the first convex portion 221, and a first mounting hole engaged with the damping shaft 500 is provided on the first concave portion 211. The damping shaft 500 is disposed in the first mounting hole, so that the first clamping arm 210 and the second clamping arm 220 are rotatably connected.

[0055] Furthermore, one end of the earphone body 100 is provided with a second protrusion 110, and correspondingly, one end of the first clamping arm 210 is provided with a second recess 212, that is, one end of the first clamping arm 210 away from the first recess 211 is provided with the second recess 212, and the second protrusion 110 is adapted to be mutually engaged with the second recess 212. A damping shaft 500 is provided on the second protrusion 110, and a second mounting hole mutually engaged with the damping shaft 500 is also provided on the second recess 212. The damping shaft 500 is located in the second mounting hole, so that the earphone body 100 and the first clamping arm 210 are rotatably connected through the damping shaft 500.

[0056] It can be understood that one end of the earphone holder 300 is provided with a third protrusion 310, and correspondingly, one end of the second clamping arm 220 is provided with a third recess 222, that is, one end of the second clamping arm 220 away from the first protrusion 221 is provided with the third recess 222, and the third protrusion 310 is suitable for mutually engaging with the third recess 222. The third protrusion 310 is provided with a damping shaft 500, and the third recess 222 is also provided with a third mounting hole mutually engaging with the damping shaft 500. The damping shaft 500 is located in the third mounting hole, so that the earphone holder 300 and the second clamping arm 220 are rotatably connected through the damping shaft 500.

[0057] In this embodiment, the first clamping arm 210 and the second clamping arm 220, the first clamping arm 210 and the earphone body 100, and the second clamping arm 220 and the earphone holder 300 are all connected by a damping shaft 500. When in use, the consumer can adjust the opening and closing angle of the clamping assembly 200 through the damping shaft 500 between the first clamping arm 210 and the second clamping arm 220, and can maintain this opening and closing angle for a long time. When the consumer needs to adjust the folding Bluetooth headset to a storage state, it is only necessary to adjust the first clamping arm 210 and the second clamping arm 220 to the same straight line, that is, the opening and closing angle between the first clamping arm 210 and the second clamping arm 220 is set to 180°. Accordingly, the earphone body 100 is rotated to store the earphone body 100 in the accommodating space, and the earphone holder 300 is rotated to store the earphone holder 300 in the accommodating space, thereby reducing the volume of the folding Bluetooth headset, which is convenient for consumers to carry.

[0058] In one embodiment, the damping shaft 500 is further described in this embodiment. Specifically, the damping shaft 500 is provided with limiting protrusions evenly arranged along the circumferential direction of the damping shaft 500, and the side wall of the first mounting hole is provided with limiting grooves matching the limiting protrusions. It can be understood that the damping shaft 500 on the first protrusion 221 of the second clamping arm 220 is arranged in the first mounting hole, so that the limiting protrusion is clamped in the limiting groove. When the consumer needs to adjust the opening and closing angle of the first clamping arm 210 and the second clamping arm 220, the consumer only needs to rotate the first clamping arm 210 and the second clamping arm 220 to the corresponding position, so that the limiting protrusion and the limiting groove are clamped and matched with each other, thereby allowing the clamping assembly 200 to maintain a fixed opening and closing angle for a long time.

[0059] It is understandable that the damping shaft 500 of the second convex portion 110 is provided with limiting protrusions evenly arranged along the circumferential direction of the damping shaft 500, and the side wall of the second mounting hole is provided with limiting grooves matching the limiting protrusions, so that the earphone body 100 and the first clamping arm 210 can maintain a fixed opening and closing angle for a long time. The damping shaft 500 of the third convex portion 310 is provided with limiting protrusions evenly arranged along the circumferential direction of the damping shaft 500, and the side wall of the third mounting hole is provided with limiting grooves matching the limiting protrusions, so that the earphone holder 300 and the second clamping arm 220 can maintain a fixed opening and closing angle for a long time.

[0060] In this embodiment, when the consumer needs to wear the foldable Bluetooth headset on the ear, the clamping assembly 200 is in the use mode. The consumer can adjust the opening and closing angle between the first clamping arm 210 and the second clamping arm 220 according to the specific conditions of the ear, and wear the foldable Bluetooth headset on the ear. The headset body 100 and the first clamping arm 210 are located on the front side of the human auricle, and the second clamping arm 220 and the headset support 300 are located on the back side of the auricle, which is not easy to fall off, thereby improving the wearing experience of the consumer. At the same time, the consumer can also adjust the opening and closing angle between the headset body 100 and the first clamping arm 210, and the opening and closing angle between the headset support 300 and the second clamping arm 220, and the adjustment is more flexible, so that the foldable Bluetooth headset fits the consumer's ear more closely, improves the consumer's comfort, and reduces the possibility of falling off.

[0061] In one embodiment, this embodiment provides another specific form of the damping shaft 500. Specifically, a damping sleeve is provided on the side wall of the first mounting hole, and the damping shaft 500 on the first protrusion 221 of the second clamping arm 220 is sleeved in the first mounting hole through the damping sleeve, and the damping shaft 500 and the damping sleeve are interference-fitted to ensure the damping required during the rotation of the first clamping arm 210 and the second clamping arm 220, so that the clamping assembly 200 can be maintained at a fixed opening and closing angle for a long time.

[0062] In actual production, the damping shaft 500 between the first clamping arm 210 and the earphone body 100 can be provided with a damping sleeve, or can be snap-fitted with a limiting groove and a limiting protrusion. Correspondingly, the damping shaft 500 between the second clamping arm 220 and the earphone holder 300 can be provided with a damping sleeve, or can be snap-fitted with a limiting groove and a limiting protrusion to achieve the purpose of rotational connection. These are not described in detail here and are all within the protection scope of the present invention.

[0063] In one embodiment, referring to the accompanying drawings, Figures 1 to 4 The earphone body 100 includes a shell, and the shell is provided with a sound outlet 120 and a charging PIN pin 130. It is worth noting that the shell is provided with a receiving cavity, and a circuit board, a battery, a first magnet and a speaker are provided in the receiving cavity. The battery and the speaker are electrically connected to the circuit board, and the battery is electrically connected to the charging PIN pin 130, and the battery is charged through the charging PIN pin 130.

[0064] In one embodiment, in this embodiment, the first clamping arm 210 and the second clamping arm 220 are made of soft rubber material, which can reduce the discomfort caused to consumers by the clamping assembly 200 clamping on the auricle.

[0065] Preferably, the outer surface of the earphone holder 300 is covered with a rubber cover to improve the wearing comfort of consumers.

[0066] In one embodiment, this embodiment also provides a combined device, see the accompanying drawings of the specification Figure 4 The combined device includes a foldable Bluetooth headset of any of the above embodiments and a wearable device 400. A second magnet is provided in the wearable device 400, and an inner groove is provided on the wearable device 400. The inner groove is suitable for interlocking with the foldable Bluetooth headset, and the first magnet and the second magnet are mutually adsorbed and matched to fix the foldable Bluetooth headset on the wearable device 400. In this way, the foldable Bluetooth headset in the storage state can be combined with the wearable device 400, and is sucked on both sides of the wearable device 400, which is convenient to take.

[0067] Preferably, a charging socket that matches the charging PIN needle 130 is provided in the inner groove. When the foldable Bluetooth headset is stored in the wearable device 400, the charging socket and the charging PIN needle are electrically connected to each other, thereby charging the foldable Bluetooth headset.

[0068] It should be noted that the above embodiments can be freely combined as needed. The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
