Description

Technical Field

[0001] The present invention relates to the technical field of Bluetooth earphones, and in particular to an earclip-stabilized TWS Bluetooth earphone. Background Art

[0002] With the popularization of wireless audio devices, especially true wireless stereo (TWS) Bluetooth earphones, users' demand for a comfortable and convenient audio experience is increasing day by day. Earclip-type TWS Bluetooth earphones have become a popular product in the market due to their unique wearing method and wireless connection characteristics. However, there are some technical problems in the design of existing earclip-type earphones, which affect the use experience and durability of the earphones.

[0003] Traditional earclip-type earphones usually include two housings connected by a wire. These housings are fixed on both sides of the ear by bending the elastic frame in the middle of the earphone. Since the wire between the earphone housings is threaded through the elastic member, when the elastic frame is bent to adapt to different ear shapes, the effective distance between the two housings will change, which means that the actual required length of the wire will also change accordingly. In the current design, the wire is usually placed in a movable manner, so that during actual use, due to the continuous change of length, the wire is extremely prone to twisting and pulling. This twisting and pulling not only affects the service life of the earphone, but may also cause discomfort to the user's ears.

[0004] Based on this, in order to solve the above problems, we propose an earclip-stabilized TWS Bluetooth earphone. Summary of the Invention

[0005] The purpose of the present invention is to solve the disadvantages in the prior art that due to the continuous change of the length of the elastic frame, the wire is extremely prone to twisting and pulling, etc., and to propose an earclip-stabilized TWS Bluetooth earphone.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions: Design an earclip-stabilized TWS Bluetooth earphone, including: a first housing configured with a sound module; and a second housing configured with a power supply and a control module; an elastic frame is connected between the first housing and the second housing; wherein, a wire guiding and constraining structure for guiding and constraining the wire is arranged inside the elastic frame, and a flexible member is detachably connected to the side surface of the first housing close to the second housing. The elastic frame and the wire guiding and constraining structure can effectively prevent the wire from being wound and mechanically worn, improving the durability and stability. The detachable connection of the flexible member is beneficial to maintenance, upgrade and personalized adjustment, enhancing the wearing comfort of the user and the stability of the overall earphone.

[0007] Furthermore, the elastic frame includes a housing and a bridge installed in the housing. An elastic member is installed inside the bridge, and the wire bundling structure is installed inside the bridge. The embedded design of the bridge makes the overall structure more compact and fully utilizes the internal space. The elastic member can effectively absorb external impacts, reduce the movement of internal components, further fix the wire bundling structure, ensure that the wires are always in an ideal guiding state, and extend the service life of the earphones.

[0008] Furthermore, the bridge includes an arc-shaped main body; a wire routing groove and two card slots are arranged on the bottom surface of the arc-shaped main body, and the two card slots are formed on both sides of the wire routing groove. The wire routing groove provides a dedicated channel for the wires, ensuring clear and reliable wire routing. The two card slots on both sides provide installation sites for subsequent fixing of the elastic member and other connecting parts, making the overall assembly more stable, with a compact and beautiful structure.

[0009] Furthermore, the elastic member is a U-shaped structural member; the two free ends of the elastic member pass through the inside of the two card slots, and bending ends are formed on the two free ends of the elastic member. The arc-shaped main body is provided with mounting holes at the card slots, and the bending ends are clamped in the mounting holes. The U-shaped design can provide sufficient elasticity to absorb the stress and vibration generated during use. The clamping method of the bending ends and the mounting holes ensures the fixing effect, is not easy to loosen, and is also convenient for installation and disassembly, ensuring the simplicity and reliability of the assembly process.

[0010] Furthermore, the wire bundling structure includes an upper clamping plate and a lower clamping plate installed in the wire routing groove. Guide grooves for the wires to pass through are arranged on the opposite surfaces of the upper clamping plate and the lower clamping plate; a connecting column is fixedly installed at the lower end of the upper clamping plate, and a through hole for avoiding the connecting column is arranged on the end surface of the lower clamping plate. The wire is double-sidedly constrained by the clamping plate structure, making the wire fixing more firm and not easy to shift. The design of the connecting column and the through hole ensures the matching accuracy between the clamping plates, protects the wires, and prevents the wires from loosening due to vibration, thereby improving the durability of the overall structure.

[0011] Furthermore, there are two wire bundling structures. One wire bundling structure is connected inside the wire routing groove through a fastener, and the other wire bundling structure is slidably connected inside the wire routing groove. The fixed wire bundling structure provides long-term and stable wire guiding, while the sliding structure allows for a certain amount of displacement compensation to adapt to the fine adjustment caused by wearing or operation. The complementary use of the two connection methods ensures the safety of the circuit during the dynamic use of the earphones, can adapt to mechanical stress, and improves the service life and reliability.

[0012] Further, first chutes for avoiding the elastic member are provided at the ends of the two card slots, and a second chute communicating with the wire groove is provided at the bottom of the arc-shaped main body; a connecting piece is fixedly installed on the inner side surface of the elastic member, and the connecting piece is connected to the wire bundling structure through a fastener. The provision of the chutes can reduce the friction between components, ensure smooth movement between the elastic member and the card slot, thereby reducing the risk of wear. The firm connection between the connecting piece and the wire bundling structure enables the overall components to work in coordination, ensures the structural stability, and effectively prevents the displacement of the internal circuit caused by loosening.

[0013] Further, the flexible member is an airbag; an installation position is provided on the side of the first housing, and the airbag is connected to the installation position through a connecting structure. As a flexible member, the airbag has good buffering and shock-absorbing effects, can effectively absorb external impacts, and improve the wearing comfort. Through the dedicated installation position and connecting structure, the combination between the airbag and the housing is more firm, and while maintaining the flexible function, the stability of the overall structure is also ensured.

[0014] Further, the connecting structure includes a clamping post fixed to the back end of the airbag. A plurality of notches are provided along the end of the clamping post, and each two notches form a clamping arm. A clamping block is provided on the outer side of the clamping arm. A clamping hole is provided on the end surface of the installation position, the clamping post is inserted into the clamping hole, and the clamping block abuts against the side wall of the clamping hole.

[0015] The meshing design of the clamping post and the clamping hole provides a reliable locking mechanism to ensure that the airbag will not easily fall off when subjected to external forces. The multi-notch and clamping arm design can not only disperse the force, but also allow a certain amount of fine adjustment, making the connecting structure both firm and flexible to a certain extent, which is beneficial to adapting to different assembly requirements.

[0016] Further, the installation position is an arc-shaped groove, and the flexible member is coupled in the arc-shaped groove. The arc-shaped groove fits the shape of the airbag, which not only ensures the stability after installation, but also optimizes the fitting degree during wearing. This design enables the airbag to play a buffering and shock-absorbing role while further improving the aesthetics and ergonomic comfort of the overall structure.

[0017] The beneficial effect of the earclip-stabilized TWS Bluetooth headset proposed by the present invention is as follows: In the earclip-type headset disclosed in the present invention, a wire bundling structure is arranged inside the elastic frame to restrict the movement of the wire. When the elastic frame undergoes bending deformation, relative displacement can be generated by the elastic member inside the elastic frame to drive the wire to move synchronously inside the elastic member, so as to eliminate the problems of excessive length twisting or excessive short pulling of the wire caused by the change in the effective length between the first housing and the second housing, greatly improving the overall durability.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Referring to Figures 1 - 12 As an embodiment of the present invention, it discloses an earclip-stabilized TWS Bluetooth headset. Those skilled in the art know that generally two such Bluetooth headsets are configured, respectively used for sound production in the left and right channels. Since the two headsets have the same structure, only the structure of one Bluetooth headset will be described in detail in this embodiment.

[0022] Referring toFigure 2 Specifically, the Bluetooth headset includes a first housing 1 configured with a sound module 11. The sound module 11 can be set as a speaker module, and its specific installation method is a conventional means for those skilled in the art, so it will not be elaborated here.

[0023] And a second housing 2 configured with a power supply and control module 21. The power supply and control module 21 includes a rechargeable battery and a control board. The control board is connected to a terminal device through a wireless module such as Bluetooth. In addition, in this embodiment, the control board and the sound module 11 are connected by a wire 4.

[0024] Refer to Figure 1 、 Figure 2 Between the first housing 1 and the second housing 2, an elastic frame 3 is connected. The elastic frame 3 is integrally in a C-shaped structure and has a certain elastic force to clamp the first housing 1 and the second housing 2 on the ear. Among them, a wire bundling structure 5 for guiding and restraining the wire 4 is arranged inside the elastic frame 3. A flexible member 6 is detachably connected to the side of the first housing 1 close to the second housing 2. The flexible member 6 is used to fit the inner side of the ear to improve the wearing comfort.

[0025] Refer to Figure 3 In some embodiments, the elastic frame 3 in the present invention includes a housing 31 and a bridge 32 embedded in the housing 31. An elastic member 33 is installed inside the bridge 32. The wire bundling structure 5 is installed inside the bridge 32. Specifically, in this embodiment, the housing 31 is set as a flexible structural member, preferably a silicone sleeve, and the bridge 32 can be set as a plastic part. In addition, the elastic member 33 in this embodiment is an elastic sheet, including but not limited to stainless steel parts, chromium alloy parts or titanium alloy parts, etc.

[0026] Refer to Figure 4 、 Figure 5 Specifically, the bridge 32 in the present invention includes an arc-shaped main body 321.

[0027] A wire groove 322 and two card slots 323 are arranged on the bottom surface of the arc-shaped main body 321. The two card slots 323 are formed on both sides of the wire groove 322. In this embodiment, the wire groove 322 is a closed structure, and the card slot 323 is a one-side open structure. Of course, in other embodiments, the card slot 323 can also be set as a closed structure. Those skilled in the art can choose according to actual needs and are not limited here. During specific assembly, the wire 4 can be threaded through the inside of the wire groove 322 to electrically connect the control board and the sound module 11. In addition, the elastic member 33 is installed inside the two card slots 323.

[0028] Based on the above embodiments, in this embodiment, the elastic member 33 is a U-shaped structural member. Of course, the overall U-shaped structural member is also in an arc structure adapted to the arc-shaped main body 321.

[0029] Referring to Figure 8 , both free ends of the elastic member 33 are inserted into the interiors of the two card slots 323. Bent ends 331 are formed on both free ends of the elastic member 33. The bent ends 331 and the elastic member 33 are bent at a right angle. The arc-shaped main body 321 is provided with mounting holes at the card slots 323, and the bent ends 331 are clamped in the mounting holes.

[0030] Specifically, in this embodiment, by opening two holes at the bottom of the arc-shaped main body 321, since the elastic member 33 is designed as a U-shaped structure as a whole, when the elastic member 33 is inserted into the interiors of the two card slots 323, the bent ends 331 are clamped in the two mounting holes to form two locking points for the elastic member 33. When the elastic frame 3 needs to be bent and expanded during the process of wearing the earphone so that the first housing 1 and the second housing 2 can be opened and enter the ear, in the present invention, one end of the entire elastic member 33 is locked and the other end is movably arranged. Therefore, when the elastic frame 3 is bent, the elastic member 33 can generate relative deformation movement, and it will not cause the middle yield force to be too large due to both ends being locked, resulting in damage to the elastic member 33. Thus, the durability of the elastic member 33 can be effectively improved.

[0031] Referring to Figure 6 , Figure 7 , optionally, in the embodiment of the present invention, the wire bundling structure 5 includes an upper clamping plate 51 and a lower clamping plate 52 installed in the wire routing groove 322. Guide grooves 53 for the wire 4 to pass through are formed on the opposite surfaces of the upper clamping plate 51 and the lower clamping plate 52, and the wire 4 is constrained between the two opposite guide grooves 53.

[0032] Wherein a connecting column 54 is fixedly installed at the lower end of the upper clamping plate 51, and a through hole for avoiding the connecting column 54 is formed on the end surface of the lower clamping plate 52. Specifically, in this embodiment, the interior of the connecting column 54 has a threaded hole to facilitate connection with subsequent fasteners. During the assembly process, first, the wire 4 is passed between the upper clamping plate 51 and the lower clamping plate 52, and then the connecting column 54 on the upper clamping plate 51 is passed through the through hole of the lower clamping plate 52 for positioning. After positioning, the upper clamping plate 51 and the lower clamping plate 52 are both pushed into the interior of the wire routing groove 322 for subsequent connection. The specific connection method will be described later and will not be elaborated here.

[0033] Referring to Figure 8, It should be noted that in the embodiment of the present invention, two wire bundling structures 5 are provided. One wire bundling structure 5 is connected inside the wire routing groove 322 through a fastener, and the other wire bundling structure 5 is slidably connected inside the wire routing groove 322. That is, in the present invention, the connection of the wire 4 also adopts the method of fixing one end and moving the other end. From the above description, it can be seen that when the entire elastic frame 3 is bent, due to the change in the distance between the first housing 1 and the second housing 2, the adapted length of the wire 4 will also change. In this embodiment, by processing a wire bundling structure 5 and fixedly connecting it inside the wire routing groove 322 through a fastener, and the other adopting a sliding connection method, the length of the wire 4 can be adaptively adjusted.

[0034] Furthermore, in this embodiment, the free end of the elastic member 33 and the slidable wire bundling structure 5 are both on the side close to the first housing 1. Of course, the wire 4 should also be freely arranged in the first housing 1. In this way, when the length of the wire 4 is adaptively adjusted, the excess wire 4 can be pushed into the first housing 1 to meet the technical requirements in the above solution.

[0035] Refer to Figure 9 , Figure 10 , In some embodiments, first chutes 324 for avoiding the elastic member 33 are provided at the ends of the two card slots 323 in the present invention. Specifically, in this embodiment, the bent part in the middle of the elastic member 33 slides in the two first chutes 324. The design of the two first chutes 324 is used to ensure guiding the elastic member 33 during the bending deformation process. A second chute 325 communicating with the wire routing groove 322 is provided at the bottom of the arc-shaped main body 321; A connecting piece 332 is fixedly installed on the inner side surface of the elastic member 33. The connecting piece 332 is connected to the wire bundling structure 5 through a fastener. Specifically, it should be noted that in the present invention, the fasteners can all be set as bolts. In the present invention, the connecting piece 332 and the wire bundling structure 5 are connected by bolts to ensure that during the deformation of the elastic frame 3, the wire 4 can be driven by the connecting piece 332 to move synchronously, thereby improving the stability of the wire 4 extension adaptation.

[0036] Refer to Figure 7, specifically, since the wire harness structure 5 includes an upper clamping plate 51 and a lower clamping plate 52, and a connecting column 54 passing through the lower clamping plate 52 is fixed to the bottom of the upper clamping plate 51. Therefore, during the connection with the connecting piece 332, a bolt passes through the connecting piece 332, and at the same time, the bolt is threadedly connected to the connecting column 54. At this time, the connecting column 54 moves downward under the driving force of the bolt, so that the upper clamping plate 51 moves relative to the lower clamping plate 52, so that while the connecting piece 332 is connected to the connecting column 54, the upper clamping plate 51 and the lower clamping plate 52 can be synchronously driven to clamp and fix the wire 4. Similarly, the fixed wire harness structure 5 can be directly fixed by bolts passing through the bottom of the arc-shaped main body 321, so as to complete the fixation of one wire harness structure 5 and the synchronous connection of another wire harness structure 5 and the elastic member 33.

[0037] During the specific deformation process, those skilled in the art know that since the entire wire 4 is in the longest stretched state in the initial state, when the earphone needs to be worn on the ear, it is necessary to first bend and expand the entire elastic frame 3 to form a larger opening so as to stably enter the outside of the ear. During this process, since the outward expansion deformation of the elastic frame 3 will cause the distance between the first housing 1 and the second housing 2 to change, and the effective distance between them becomes smaller, the elastic member 33 and the wire 4 will have redundant parts under the influence of the tensile deformation. Since one end of the elastic member 33 in the present invention adopts locking and limiting, and the other end adopts a sliding structure design, during the tensile deformation process, the other end of the elastic member 33 slides relatively to adapt to the redundant parts generated during the above movement process, so as to reduce the stress condition of the entire elastic member 33. Similarly, since the wire 4 in this embodiment is connected to the wire harness structure 5, and the two wire harness structures 5 also adopt a design of one fixed and one sliding, and the sliding wire harness structure 5 is connected to the sliding end of the elastic member 33, so when the elastic member 33 generates an adaptive sliding process, it will also synchronously pull the wire 4 to move to eliminate the redundant parts of the wire 4. On the contrary, during the reset process, the elastic member 33 drives the wire 4 to reset, so as to improve the adaptive stability of the wire 4, so as to avoid the problem that the wire 4 in the traditional solution is damaged due to being pulled or twisted during the deformation process of the elastic frame 3 when it is freely placed, greatly improving the overall durability.

[0038] Referring to Figure 1 、 Figure 11 , in some embodiments, the flexible member 6 in the present invention is an airbag. An installation position 12 is provided on the side of the first housing 1, and the airbag is connected to the installation position 12 through a connection structure 61. Preferably, in this embodiment, the installation position 12 is an arc-shaped groove, and the flexible member 6 is coupled in the arc-shaped groove. The design of the arc-shaped groove is to avoid the problem of circumferential rotation of the flexible member 6 in the installation position 12. In this embodiment, the airbag is used to contact the inner side of the ear, which greatly improves the comfort during the wearing of this earphone.

[0039] Referring to Figure 12 , in a preferred embodiment, the connection structure 61 in the present invention includes a clamping post 611 fixed to the back end of the airbag. A plurality of notches are provided along the end of the clamping post 611, and a clamping arm 612 is formed between every two notches. A clamping block 613 is provided on the outer side of the clamping arm 612. A clamping hole 13 is provided on the end face of the installation position 12. The clamping post 611 is inserted into the clamping hole 13, and the clamping block 613 abuts against the side wall of the clamping hole 13.

[0040] It should be noted that chamfers are provided on both sides of the clamping block 613 in this embodiment. The two chamfers are used to drive the clamping arm 612 to deform by fitting the inner hole surface of the clamping hole 13 when the clamping block 613 is inserted into or pulled out of the clamping hole 13. In this way, the convenience of disassembly and assembly can be realized. Secondly, the detachable structure design further improves the convenience of subsequent replacement and cleaning.

[0041] In summary, for the earclip-type earphone disclosed in the present invention, the wire 4 is movably constrained by the wire bundling structure 5 provided inside the elastic frame 3. When the elastic frame 3 undergoes bending deformation, a relative displacement can be generated by the elastic member 33 inside the elastic frame 3 to drive the wire 4 to move synchronously inside the elastic frame 3, so as to eliminate the problems of excessive length distortion or excessive short pulling of the wire 4 due to the change in the effective length between the first housing 1 and the second housing 2, greatly improving the overall durability.

[0042] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
