Description

Technical Field

[0001] The utility model relates to the field of mobile terminal equipment, and in particular to a detachable neck-hanging TWS earphone. Background Art

[0002] At present, TWS earphones are widely used because they are wireless and have low latency. However, the disadvantage of TWS earphones lies in the battery life. Because the earphones themselves are small in size, after accommodating the chip and acoustic structure, the weight left for the battery limits the capacity of the battery, which greatly limits the battery life of the earphones. No matter how the power usage is optimized from the software, it can only get a certain small improvement, which has no obvious impact on the overall usage time.

[0003] In order to solve the problem of battery life, the current market usually adopts a combination of a charging case and TWS earphones, that is, the earphones are charged when they are not in use and stored, making full use of the time when the user is not wearing them. However, if the user wants to wear them for a long time, there is no way to charge them. Utility Model Content

[0004] In order to solve the technical problem that TWS earphones cannot be worn beyond the battery life, the utility model provides a detachable neck-hanging TWS earphone, including a neck hang and a TWS earphone, a power supply device is arranged in the neck hang, a first electrical connection structure is arranged at the end of the neck hang, and a second electrical connection structure is arranged at the end of the TWS earphone, and the first electrical connection structure and the second electrical connection structure can cooperate with each other to electrically connect the TWS earphone and the neck hang. By adding a neck hang, the neck hang and the TWS earphone can be electrically connected, so that the user can use the neck hang to charge the TWS while using the TWS earphone, thereby achieving the effect of improving the battery life.

[0005] Optionally, the first electrical connection structure is an MMCX male connector, and the second electrical connection structure is an MMCX female connector.

[0006] Optionally, the MMCX female connector of the TWS earphone is embedded in the TWS earphone, and the end of the MMCX female connector is flush with the end of the TWS earphone.

[0007] Optionally, a second protective member is also included, and the second protective member is a cover structure, and a fixing protrusion matching the size of the MMCX female connector is provided on the inner side thereof. In order to ensure that the external rain, water mist and the user's sweat are not easy to enter the TWS headset through the MMCX female connector during the normal use of the TWS headset, the added second protective member can effectively protect the sealing of the internal structure, especially by fixing the second protective member by matching the fixing protrusion with the size of the MMCX female connector, which not only has a good sealing effect, but also effectively fixes the second protective member so that it is not easy to fall off.

[0008] Optionally, the second protective member is also provided with a second fixed axis and a second fixed anchor, the second fixed axis is arranged on the inner side of the second protective member, the second fixed anchor is arranged on the other side of the second fixed axis, the width of the second fixed anchor is greater than the width of the second fixed axis, and a second accommodating space of the same size as the second fixed axis and the second fixed anchor is arranged in the TWS earphone, and the second fixed axis and the second fixed anchor are both arranged in the accommodating space. Taking into account that the second protective member cannot be fixed after the user connects the TWS earphone to the neck hanging, and the user may easily lose it, the second fixed anchor and the second fixed axis are added, and both are confined inside the TWS earphone and cannot move up and down or left and right, and can only rotate. Therefore, when in use, the second protective member can be connected to the TWS earphone and does not need to be stored.

[0009] Optionally, a first protective member is also included, and the first protective member is a cover structure, and a fixed blind hole matching the size of the MMCX male connector is provided on the inner side. When the neck strap is not in use, on the one hand, the MMCX male connector is exposed to the outside, which may cause damage to the user's neck. On the other hand, the user's sweat and external rain and water vapor can easily invade the inside of the neck strap, causing a short circuit in the internal circuit board. Therefore, adding a first protective member can effectively solve the problem that the MMCX male connector on the neck strap is easily caught by the user and increase the service life of the neck strap.

[0010] Optionally, the first protective member is further provided with a first fixed axis and a first fixed anchor, wherein the first fixed axis is provided on the inner side of the first protective member, and the first fixed anchor is provided on the other side of the first fixed axis, and the width of the first fixed anchor is greater than the width of the first fixed axis. The neck hanger is provided with a mounting hole, and the diameter of the mounting hole is greater than the diameter of the first fixed axis, but smaller than the diameter of the first fixed anchor. Because the MMCX male head protected by the first protective member uses an inwardly recessed blind hole to match the MMCX male head during the protection process, when the first protective member is opened, the first protective member cannot be directly rotated, otherwise the MMCX male head will be damaged. Therefore, the first fixed axis and the first fixed anchor are movably arranged in the neck hanger, and the first protective member can move along the axial direction of the first fixed axis, and can also rotate with the first fixed axis as the axis, which is convenient for movement and has the effect of not requiring storage.

[0011] Optionally, the first fixing anchor or the second fixing anchor is a truncated cone structure, and one end connected to the first fixing shaft or the second fixing shaft is a truncated cone bottom surface. The truncated cone structure can facilitate the installation of the first fixing anchor and the second fixing anchor, and the inclined surface of the truncated cone has a good guiding effect.

[0012] Optionally, a switching switch and a circuit board are also provided on the neck hanging, and the switching switch is electrically connected to the circuit board.

[0013] Optionally, the neck strap is also provided with a charging interface, which is electrically connected to the power supply device. The charging interface is used for charging the neck strap.

[0014] The utility model has the following technical effects:

[0015] 1. Greatly improve the battery life of TWS earphones. Compared with the traditional TWS and charging case, the utility model can be charged while the TWS earphones are in continuous use, ensuring that the earphones are out of power in some more urgent scenarios; after charging to a suitable level, the neckband can be separated from the TWS earphones, and the TWS earphones can continue to be used. The TWS earphones are used normally throughout the whole process, which greatly improves the battery life of the TWS earphones.

[0016] 2. Good service life and user experience. In order to protect the reliability of the connection structure and the internal airtightness when the TWS earphones and the neckband are not connected, protective parts are used to protect the relevant link structure to increase the service life of the equipment. While having a protective effect, it also considers how to achieve the effect of no need to store the protective parts in the connected state to improve the user experience.

[0017] 3. It has a conversion function to effectively improve charging efficiency. A switch is also set on the neckband to switch the usage mode. After the TWS earphones are connected to the neckband, the switch can be used to control the circuit board in the neckband and electrically control the TWS. The original TWS earphones are responsible for receiving Bluetooth information, and the neckband is responsible for receiving Bluetooth information. TWS only acts as a speaker, which can reduce power consumption and charge faster. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer definition of the protection scope of the present invention.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "head", "tail", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] Example 1

[0025] In this embodiment, as shown in the attached Figure 1As shown, it includes a neck hanging 1 and a pair of TWS earphones 2. Power supply devices 5 are provided on both sides of the neck hanging 1. A circuit board is provided inside the neck hanging 1 for electrically connecting various functions and control interfaces. A first electrical connection structure 3 is provided at the ends of both ends of the neck hanging 1. In the present embodiment, the first electrical connection structure 3 is an MMCX male connector. The MMCX male connector is electrically connected to the circuit board. The MMCX male connector is specifically arranged on the tails of the two ends of the neck hanging 1, and is embedded in the neck hanging 1, and the protruding part of the connector is arranged to protrude from the surface of the neck hanging 1. From the outside, the MMCX connector slightly protrudes from the plane at the end of the neck hanging 1.

[0026] In this embodiment, as shown in the attached Figure 2 As shown, it includes a first protective member 11, a first fixed shaft 12, and a first fixed anchor 13. The first protective member 11 is specifically a cover structure, and the side close to the MMCX male head is the inner side, and a fixed blind hole is provided on the inner side. The fixed blind hole is specifically a pit recessed into the first protective member 11, which is used to accommodate the partial structure of the MMCX male head protruding from the neck hanging 1. One end of the first fixed shaft 12 is linked to the inner side of the first protective member 11, and the other end is connected to the first fixed anchor 13. The first fixed shaft 12 is specifically a cylindrical structure. The first fixed anchor 13 is a truncated cone structure, and its bottom surface is connected to the first fixed shaft 12. In this embodiment, the external structure of the neck hanging 1 is also provided with an integral mounting hole for mounting the first protective member 11, the first fixed shaft 12, and the first fixed anchor 13. The diameter of the mounting hole is larger than the diameter of the first fixed shaft 12, and smaller than the bottom surface diameter of the first fixed anchor 13. The first protective member 11, the first fixed shaft 12, and the first fixed anchor 13 are all made of elastic material.

[0027] During installation, the first protective member 11, the first fixed shaft 12, and the first fixed anchor 13 are formed as a whole. First, the top surface of the first fixed anchor 13 is close to the installation hole. Since the bottom diameter of the truncated cone is larger than the diameter of the installation hole, it is necessary to force the first fixed anchor 13 as a whole to be slowly inserted through its side, and then it is inserted into the installation hole after a certain deformation. After the first fixed anchor 13 is installed and inserted into the installation hole, because the diameter of the first fixed shaft 12 is smaller than the installation hole, the first fixed shaft 12 can be pulled in or out of the installation hole at will, so that the first protective member 11, the first fixed shaft 12, and the first fixed anchor 13 can be pulled out to the outside of the end of the neck hanging 1 as a whole, and can be rotated with the first fixed shaft 12 as the axis, so as to cover or open the MMCX male part. When opened, because the bottom diameter of the first fixing anchor 13 is larger than the diameter of the mounting hole, the fixing anchor will be stuck on the neck hanging 1, so that the first protective member 11, the first fixing shaft 12, and the first fixing anchor 13 are suspended on the neck hanging 1 as a whole without the need for additional storage.

[0028] In this embodiment, as shown in the attached Figure 3As shown, each TWS headset 2 is provided with a second electrical connection structure 4. In the present embodiment, the electrical connection structure is an MMCX female head. The specific MMCX female head is arranged at the end of the TWS headset 2, and its bottom surface is flush with the bottom surface of the TWS headset 2. The TWS headset 2 specifically also includes a second protective member 21, a second fixed shaft 22, and a second fixed anchor 23. The second protective member 21 is a cover structure, and its side close to the MMCX female head is the inner side. A fixed protrusion is arranged on its inner side. The size of the fixed protrusion matches the shape and size of the MMCX female head. The second protective member 21 can be fixed on the MMCX female head through the fixed protrusion to achieve a sealing effect. The second fixed shaft 22 is a cylindrical structure, one end of which is connected to the second protective member 21, and the other end is connected to the second fixed anchor 23. The second fixed anchor 23 is a truncated cone structure, and its bottom surface is connected to the second fixed shaft 22. Inside the TWS earphone 2, a dedicated accommodation space for the second fixed axis 22 and the second fixed anchor 23 is provided, that is, the size and shape of the accommodation space are the same as the second fixed axis 22 and the second fixed anchor 23, and the opening of the accommodation space is provided at the bottom of the TWS earphone 2. The second protective member 21, the second fixed axis 22, and the second fixed anchor 23 are all made of elastic material.

[0029] During installation, because the opening of the accommodating space has the same diameter as the second fixed axis 22, the second fixed anchor 23 needs to be pressed and deformed, inserted into the opening of the accommodating space, and pushed forward as a whole until the fixed anchor is pushed to a position with the same shape, and the second fixed anchor 23 restores its original shape. At this time, the second fixed axis 22 and the second fixed anchor 23 are both confined in the accommodating space and cannot move up and down or left and right, and can only rotate. Therefore, the second protective member 21 can only be rotated, and the MMCX female head can be covered or opened by rotation. In the open state, because the second fixed anchor 23 and the second fixed axis 22 cannot be displaced, the second protective member 21 will be fixed at the current position of the rotation and does not need to be stored.

[0030] When the TWS earphone 2 is used alone, the TWS earphone 2 is separated from the neck hanging 1. At this time, the first protective member 11 of the neck hanging 1 and the second protective member 21 of the TWS earphone 2 are fixed on the MMCX male and MMCX female heads respectively. Because they are fixed and sealed, the sweat of normal users and the liquid in the external environment cannot enter the device through the MMCX male and MMCX female heads. At the same time, because the MMCX male head on the neck hanging 1 protrudes from the bottom surface of the neck hanging 1, it is easy to hang on the user's neck after long-term use. Therefore, the first protective member 11 can also effectively protect the user's neck.

[0031] When the TWS earphone 2 needs to be charged, the user needs to separate the second protective member 21 on the TWS earphone 2 from the MMCX female connector by rotating. During the separation process, because the second protective member 21 has only a fixed protrusion, a certain torque needs to be applied during separation to achieve the deformation of the second protective member 21, thereby achieving the separation of the second protective member 21 from the MMCX female connector. The second protective member 21 can be rotated until the MMCX female connector is completely exposed. At this time, no processing is required on the second protective member 21, because the second fixed shaft 22 and the second fixed anchor 23 connected to the second protective member 21 are fixed, so the second protective member 21 is also fixed in this position. It is also necessary to separate the first protective member 11 on the neck hanging 1. The user can pinch the first protective member 11 and pull it out. Because the first protective member 11 is connected to the first fixed shaft 12, the width of the first fixed shaft 12 is smaller than the size of the mounting hole, so the first fixed shaft 12 can be pulled out or extended along the direction of the mounting hole, but the first fixed shaft 12 cannot be pulled out of the mounting hole because the other end of the first fixed shaft 12 is connected to the first fixed seat. The first fixed seat is a truncated cone structure, and its bottom diameter is larger than the diameter of the mounting hole. Therefore, the first fixed anchor 13 will limit the pulling out of the first fixed shaft 12. After the first fixed shaft 12 is pulled out to a certain length, the first protective member 11 can be rotated along the first fixed shaft 12 to expose the MMCX male head.

[0032] After the MMCX female connector of the TWS earphone 2 and the MMCX male connector of the neckband 1 are exposed, they can be directly plugged in so that the neckband 1 and the TWS earphone 2 are electrically connected to achieve the charging effect.

[0033] In addition, in this embodiment, a switching switch is also provided on the neck hanging 1. By toggling the switching switch, the Bluetooth reception work can be transferred from the TWS earphone 2 to the Bluetooth chip of the neck hanging 1, and the TWS earphone 2 is transformed into a speaker function for receiving the audio signal transmitted by the neck hanging 1 and converting it into a sound signal, thereby reducing power consumption and improving the charging efficiency of the TWS earphone 2.

[0034] Example 2

[0035] In this embodiment, the difference from Embodiment 1 is that the second electrical connection structure 4 on the TWS earphone 2 is specifically an MMCX male head, and the first electrical connection structure 3 on the neck hanging 1 is specifically an MMCX female head. The corresponding second protective member 21 is a fixed blind hole with an inward depression, and the first protective member 11 is a fixed protrusion protruding outward. The TWS is provided with a mounting hole, and the diameter of the mounting hole is larger than the second fixed axis 22 and smaller than the bottom surface of the second fixed anchor 23. The neck hanging 1 is provided with a receiving space, and the first fixed axis 12 and the first fixed anchor 13 are both confined in the receiving space.

[0036] Example 3

[0037] The present embodiment is different from the first embodiment in that a charging interface is further provided on the neckband 1 , through which the power supply device 5 of the neckband 1 can be charged.

[0038] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
