Description

Technical Field

[0001] This invention belongs to the field of Bluetooth headset technology, and particularly relates to a Bluetooth headset and a smart headband device having the Bluetooth headset. Background Technology

[0002] Bluetooth headsets are hands-free headphones that utilize Bluetooth technology, allowing users to wear and use them conveniently without wires. Meanwhile, with technological advancements, head-mounted smart devices have emerged in recent years. These devices are worn on the head, facilitating direct interaction with the body's senses, such as vision and hearing, enhancing the human-computer interaction experience. Examples include Google Glass and HTC VR glasses, which employ optical imaging principles, constructing a head-mounted smart device with a structure similar to eyeglasses. This allows for direct contact with the eyes, improving visual imaging and enhancing comfort when worn.

[0003] However, most existing head-mounted smart devices use a strap to be worn on the head and require a matching headset for use. This separate design of the smart device and headset is inconvenient for both to use and to carry around. Therefore, it is necessary to provide a Bluetooth headset that can be used seamlessly with head-mounted smart devices. Summary of the Invention

[0004] The purpose of this invention is to provide a Bluetooth headset and a head-mounted smart device having the Bluetooth headset, aiming to provide a Bluetooth headset that can be used in conjunction with a head-mounted smart device, so that it can be integrated with the head-mounted smart device, making it convenient to use and carry when going out.

[0005] To achieve the above objectives, this invention provides a Bluetooth headset for connecting and adapting to the main support of a headband smart device, comprising a headset body, a connecting component, and a headset support, wherein the headset body and the headset support are respectively connected to opposite ends of the connecting component;

[0006] The headphone bracket includes an inner side and an outer side. The inner side is provided with spaced-apart limiting members and locking holes along its length. The limiting members extend and protrude away from the outer side and form a concave step. The locking holes are formed by the inner side tilting towards the outer side until they penetrate the headphone bracket. A locking step extending to the edge of the locking hole is provided on the outer side. A semi-enclosed limiting sliding groove is formed on the outer periphery of the inner side on one side of the locking hole.

[0007] The main support can slide along the limiting sliding groove until one end of the main support passes through the locking hole and is locked on the locking step, and the other end of the main support abuts against the limiting member and is accommodated in the concave step.

[0008] Optionally, the connecting assembly includes a fixed base, an adjusting base, and a support arm, wherein the fixed base is connected and fixed to the outer surface.

[0009] The adjustment seat includes a base plate, a positioning shaft, a nut, and a spring washer. The base plate is provided with a rotating platform that is rotatably connected to one end of the support arm. The headphone body is connected to the other end of the support arm.

[0020] The reset torsion spring is sleeved outside the reset rotating shaft, and one end of the reset torsion spring is hooked to the swing arm block, while the other end of the reset torsion spring abuts against the reset block.

[0021] Rotating the support arm upwards around its pivot axis causes the engagement part to sequentially disengage from the upper end of the swing arm block, then engage with the bottom end of the stop block, and finally disengage from the bottom end of the reset block. The reset block rotates under the action of the reset torsion spring and presses against the bottom end of the stop block. At this point, the engagement part is reset by the action of the support arm torsion spring to engage with the upper end of the swing arm block again.

[0022] Optionally, the rocker arm block includes a snap-fit ​​part located at the upper end for engaging with the snap-fit ​​part and a rocker arm part connected to both sides of the snap-fit ​​part and extending downward.

The rotating part is rotatably connected to the two swing arms via the reset shaft. The upper end of the reset part is provided with a reset inclined surface that cooperates with the inclined surface of the stop inclined surface, and the lower end of the reset part is provided with a reset arc groove for pre-positioning the engagement part.

[0027] This invention also provides a head-mounted smart device, which includes a smart component and the aforementioned Bluetooth headset. The side of the smart component is provided with a main support that is connected to the headset bracket of the headset body.

[0028] The Bluetooth headset and the head-mounted smart device with the Bluetooth headset provided in the embodiments of the present invention have at least one of the following technical effects: The Bluetooth headset of the present invention is provided with a main body bracket for the head-mounted smart device to be adapted to connect the headset bracket. The headset bracket has a limiting member and a locking hole on its inner side. The limiting member also forms a concave step. The locking hole is formed by tilting the inner side towards the outer side until it penetrates the headset bracket. A locking step is formed at the edge of the locking hole. At the same time, a semi-enclosed limiting sliding groove is formed on the outer periphery of one side of the locking hole. When adapted to connect with the main body bracket of the head-mounted smart device, the main body bracket is slid in the limiting sliding groove toward the locking hole until it passes through the locking hole and is locked on the locking step. At the same time, the other end of the main body bracket is embedded in the concave step formed in the limiting member and accommodated therein. In this way, the Bluetooth headset achieves a stable connection with the main frame through the headset stand, allowing the head-mounted smart device to be equipped with the Bluetooth headset. Furthermore, when it is necessary to remove the Bluetooth headset, force is applied to the main frame through the locking hole until the headset stand is detached from the main frame, thus releasing the entire Bluetooth headset assembly. This is simple and practical, enabling the head-mounted smart device to have a detachable and compatible Bluetooth headset, making the head-mounted smart device a unified whole, convenient for use and carrying when going out.

[0069] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The following description is based on the accompanying drawings. Figures 1-20 The described embodiments are exemplary and intended to explain embodiments of the invention, and should not be construed as limiting the invention.

[0070] In the description of the embodiments of the present invention, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0071] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0072] In the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0073] In one embodiment of the present invention, such as Figures 1-2 As shown, a Bluetooth headset 100 is provided for adapter connection with the main support 40 of a head-mounted smart device. Combined with... Figures 19-20 That is, the Bluetooth headset 100 of the present invention can be specifically adapted for use in head-mounted smart devices. Generally, head-mounted smart devices have a smart component 200, and the side of the smart component 200 is provided with a main support 40. The Bluetooth headset 100 of the present invention can be adapted to and detachably connected to the main support 40.

[0074] Specifically, such as Figures 1-3 As shown, the Bluetooth headset 100 includes a headset body 10, a connection component 20, and a headset stand 30, as... Figures 4-5 As shown, the earphone body 10 and the earphone bracket 30 are respectively connected to opposite ends of the connecting component 20. The earphone body 10 is a conventional generating device that can employ conventional technology. This embodiment does not modify the earphone body 10, therefore the specific structure of the earphone body 10 will not be described in detail. The connecting component 20 is used to centrally connect the earphone body 10 and the earphone bracket 30. The earphone bracket 30 is specifically adapted to connect to the main bracket 40 of the smart component 200, and the earphone bracket 30 is also one of the key improvements in this embodiment. The structure of the earphone bracket 30 will be further described and explained below.

[0075] like Figures 4-5As shown, the headphone bracket 30 of this embodiment includes an inner side portion 31 and an outer side portion 32. Typically, the inner side portion 31 refers to the side facing the human body when worn, while the outer side portion 32 faces away from the human body, where the human body usually refers to the head (including the face). The headphone bracket 30 is a long strip structure with a length direction. The inner side portion 31 has spaced-apart limiting members 33 and locking holes 34 along its length direction. These spaced-apart limiting members 33 and locking holes 34 are typically positioned on opposite sides or near opposite ends of the headphone bracket 30 along its length. The limiting member 33 extends and protrudes away from the outer side portion 32, forming a concave step 35. That is, the limiting member 33 protrudes in the direction facing the human body, and the concave step 35 is formed recessed near the end of the limiting member 33, creating an open or semi-enclosed receiving groove structure for engaging with a structural component to limit and position that component. The locking hole 34 is formed by the inner side portion 31 inclined towards the outer side portion 32 until it penetrates the earphone bracket 30. The locking hole 34 has a certain length in the longitudinal direction, but its depth is not consistent at every position in the direction from the inner side portion 31 to the outer side portion 32 (depth direction). Furthermore, a locking step 36 extending to the edge of the locking hole 34 is provided on the outer side portion 32. This locking step 36 is formed on the outer side portion 32 but connects to the edge of the locking hole 34 (the connection means there is a contact point). A semi-enclosed limiting sliding groove 37 is formed on the outer periphery of the inner side portion 31 on one side of the locking hole 34. The semi-enclosed limiting sliding groove 37 surrounds the outer periphery of the main body bracket 40, and the formed track guides and limits the sliding movement of the main body bracket 40.

[0076] Thus, combined Figure 5 and 19 As shown, the main support 40 can slide along the limiting sliding groove 37 until one end of the main support 40 passes through the locking hole 34 and is locked onto the locking step 36, while the other end of the main support 40 abuts against the limiting member 33 and is accommodated in the concave step 35. The main support 40 is stably confined between the concave step 35 and the locking step 36, making it difficult to fall off. However, when a force is applied to the main support 40, it can disengage from the earphone bracket 30, demonstrating a very ingenious structural design.

[0077] The following combination Figures 1-5In sections 19-20, the Bluetooth headset 100 in this embodiment of the invention will be further described. It is provided with a main body bracket 40 for a head-mounted smart device to be adapted to connect with a headset bracket 30. In the headset bracket 30, a limiting member 33 and a locking hole 34 are provided on its inner side 31. The limiting member 33 also forms a concave step 35. The locking hole 34 is formed by tilting the inner side 31 toward the outer side 32 until it penetrates the headset bracket 30. A locking step 36 is formed at the edge of the locking hole 34. At the same time, a semi-enclosed limiting sliding groove 37 is formed on the outer periphery of one side of the locking hole 34. When adapted to connect with the main body bracket 40 of the head-mounted smart device, the main body bracket 40 is slid in the limiting sliding groove 37 toward the locking hole 34 until it passes through the locking hole 34 and is locked on the locking step 36. At the same time, the other end of the main body bracket 40 is embedded in the concave step 35 formed in the limiting member 33 and accommodated therein. In this way, the Bluetooth headset 100 is stably connected to the main support 40 through the headset bracket 30, so that the head-mounted smart device is equipped with the Bluetooth headset 100. When it is necessary to remove the Bluetooth headset 100, force is applied to the main support 40 through the locking hole 34 until the headset bracket 30 is disconnected from the main support 40, thus releasing the assembly of the entire Bluetooth headset 100. This is simple and practical, allowing the head-mounted smart device to have a detachable and compatible Bluetooth headset 100, making the head-mounted smart device an integrated unit that is convenient to use and carry when going out.

[0078] In another embodiment of the invention, such as Figure 6 and 9 As shown, the improvement of this embodiment of the invention lies in the connecting component 20. This connecting component 20 allows it to rotate relative to the headphone bracket 30, thus enabling the headphone body 10 connected to the connecting component 20 to rotate at an angle, which facilitates the adjustment of the headphone body 10's position. Specifically, the connecting component 20 includes a fixing base 21, an adjusting base 22, and a support arm 23. The fixing base 21 is fixedly connected to the outer surface 32 of the headphone bracket 30; for example, a pin and a socket can be used to connect the fixing base 21 to the outer surface 32 of the headphone bracket 30, and screws can be added for further fixation.

[0079] Among them, such as Figure 9 As shown, the adjustment seat 22 includes a base plate 22a, a positioning shaft 22b, a nut 22c, and a spring washer 22d. The adjustment seat 22 is used to realize the rotation function. The base plate 22a is provided with a rotating platform 22a2 that is rotatably connected to one end of the support arm 23. The earphone body 10 is connected to the other end of the support arm 23. In this way, the support arm 23 can swing relative to the base plate 22a, thereby adjusting the clamping angle of the earphone body 10 and making it convenient for the user to wear the earphone body 10.

[0080] Furthermore, such as Figure 9 As shown, the positioning shaft 22b extends upward through the fixed base 21, and the base plate 22a is disposed on the fixed base 21 and is provided with a shaft hole 22a3 for the positioning shaft 22b to pass through; the shaft hole 22a3 is provided to avoid the base plate 22a interfering with the installation of the positioning shaft 22b.

[0081] Furthermore, such as Figure 9 As shown, the spring washer 22d is sleeved outside the positioning shaft 22b, and the nut 22c is threaded to the end of the positioning shaft 22b and presses against the spring washer 22d, so that the spring washer 22d applies pressure to the base plate 22a, and the base plate 22a forms rotational damping under this pressure. In this way, under the action of the spring washer 22d, the base plate 22a can always be pressed against the fixed seat 21. When the swing arm 23 causes the base plate 22a to rotate relative to the fixed seat 21, a certain damping feeling is formed, so that the arm 23 can achieve instant positioning after rotation, which facilitates the adjustment and positioning of the circumferential angle of the headphone body 10.

[0082] In another embodiment of the invention, such as Figures 7-8 As shown, the top of the fixing base 21 is provided with an arc-shaped groove 211, and the bottom of the base plate 22a is provided with an arc-shaped protrusion 23a1 adapted to the arc-shaped groove 211. The base plate 22a rotates relative to the fixing base 21 by means of the cooperation between the arc-shaped protrusion 23a1 and the arc-shaped groove 211. In this embodiment, the cooperation between the arc-shaped protrusion 23a1 and the arc-shaped groove 211 limits the rotation angle of the base plate 22a to the arc range of the arc of the arc-shaped groove 211. Since the angle adjustment of the earphone body 10 does not need to be excessive, the maximum adjustment angle of the earphone body 10 in two directions can be limited by the limiting position of the arc-shaped protrusion 23a1 at both ends of the arc-shaped groove 211. This also protects other structures and avoids damage to the mating parts due to excessive adjustment of the earphone body 10.

[0083] In another embodiment of the invention, such as Figure 6 and 9 As shown in Figure 11, this embodiment further improves the adjustment seat 22, enabling adjustment of the angle at which the headphone body 10 clamps the human head. Specifically, the adjustment seat 22 also includes a support arm torsion spring 22f, a swing arm block 22g, and a swing arm tension spring 22h; one end of the support arm 23 includes a horizontally arranged engagement portion 23a, a vertically arranged connecting portion 23b, and a horizontally arranged pivot portion 23c. The engagement portion 23a, connecting portion 23b, and pivot portion 23c at the end of the support arm 23 are integrally formed, roughly forming a Z shape.

[0084] Among them, such as Figure 6 , 9 As shown, the engagement portion 23a and the pivot portion 23c are respectively connected to the upper and lower ends of the connecting portion 23b and extend in opposite directions. The engagement portion 23a is provided with a clearance hole 23a1 located above the positioning shaft 22b. The pivot portion 23c is rotatably connected to the pivot table 22a2 via the support arm pivot 22a4. Thus, when the support arm 23 swings around the support arm pivot 22a4, the engagement portion 23a will move away from or closer to the positioning shaft 22b. The clearance hole 23a1 prevents interference between the engagement portion 23a and the positioning shaft 22b when the engagement portion 23a is close to the positioning shaft 22b.

[0085] Furthermore, such as Figure 6 , 9 As shown, torsion spring seats 22a6 are provided on both sides of the engagement portion 23a on the base plate 22a. The support arm torsion spring 22f is sleeved on each torsion spring seat 22a6. One end of the support arm torsion spring 22f abuts against the base plate 22a, and the other end of the support arm torsion spring 22f abuts against the side of the engagement portion 23a. In this way, the support arm torsion spring 22f can always apply pressure to the engagement portion of the support arm 23, so that the engagement portion 23a always has a force applied in one direction by the support arm torsion spring 22f. This force is used to make the engagement portion 23a engage with the swing arm block 22g.

[0086] Furthermore, such as Figure 6 , 9 As shown, a swing arm seat 22a5 is also provided on the base plate 22a. The lower end of the swing arm block 22g is rotatably connected to the swing arm seat 22a5 via a swing arm shaft 22i. A swing arm tension spring 22h is provided on both sides of the swing arm block 22g. One end of the swing arm tension spring 22h is hooked to the base plate 22a, and the other end of the swing arm tension spring 22h is hooked to the side of the swing arm block 22g, so that the upper end of the swing arm block 22g can engage with the engagement part 23a. Similarly, when the swing arm block 22g applies a pressure to the engagement part 23a of the support arm 23 under the action of the swing arm tension spring 22h, and a reaction force is applied to the swing arm block 22g, the swing arm block 22g can rotate around the swing arm shaft 22i to disengage from the engagement with the engagement part 23a of the support arm 23.

[0087] In another embodiment of the invention, such as Figures 9-11As shown, this embodiment further improves the adjustment seat 22 to enable adjustment with different gear positions. Specifically, the adjustment seat 22 also includes a reset block 22j, a reset torsion spring 22k, a gear block 22n, and a gear torsion spring 22p. The reset block 22j and the gear block 22n are rotatably mounted in the rocker arm block 22g via a reset shaft 22m and a gear shaft 22o, respectively, with the reset block 22j located below the gear block 22n. Thus, both the reset block 22j and the gear block 22n can rotate relative to the rocker arm block 22g, and their positions are staggered for coordinated operation.

[0088] Furthermore, such as Figures 9-11 As shown, the gear shift torsion spring 22p is sleeved outside the gear shift shaft 22o, and one end of the gear shift torsion spring 22p is hooked to the rocker arm block 22g, while the other end of the gear shift torsion spring 22p abuts against the rocker arm block 22g; thus, under the action of the spring force of the gear shift torsion spring 22p, the gear shift block 22n always has a downward rotational force with the gear shift shaft 22o as the axis.

[0089] Furthermore, such as Figures 9-11 As shown, the reset torsion spring 22k is sleeved outside the reset rotating shaft 22m, and one end of the reset torsion spring 22k is hooked to the swing arm block 22g, while the other end of the reset torsion spring 22k abuts against the reset block 22j. Similarly, under the spring force of the reset torsion spring 22k, the reset block 22j always has a downward rotational force with the reset rotating shaft 22m as the axis.

[0090] like Figures 9-11 As shown, after the above structural components are configured, the support arm 23 is rotated upward around the support arm pivot 22a4, which allows the engagement part 23a to sequentially disengage from the upper end of the swing arm block 22g, then engage with the bottom end of the stop block 22n, and finally press against the bottom end of the reset block 22j until it disengages from the reset block 22j. The reset block 22j rotates under the action of the reset torsion spring 22k and presses against the bottom end of the stop block 22n. At this time, the engagement part 23a is reset by the action of the support arm torsion spring 22f to engage with the upper end of the swing arm block 22g again.

[0091] like Figures 15-18As shown, the Bluetooth headset 100 in this embodiment achieves the following: when the biting part 23a engages with the upper end of the swing arm block 22g to form the first position, and the support arm 23 is swung upward to make the biting part 23a move downward, the biting part 23a will eventually engage with the stop block 22n, thus forming the second position. When the support arm 23 is swung upward to make the biting part 23a move downward, the biting part 23a will eventually come into contact with the reset block 22j and eventually disengage from the reset block 22j. At this time, the biting block presses against the reset block 22j from the opposite direction, and the reset block 22j presses against the stop block 22n under the action of the reset torsion spring 22k. The biting part 23a avoids all structural obstructions and resets to engage with the upper end of the swing arm block 22g, resetting to the first position.

[0092] In another embodiment of the invention, such as Figures 9-12 As shown, the rocker arm block 22g includes a snap-fit ​​part 22g1 located at the upper end for engaging with the snap-fit ​​part 23a, and a rocker arm part 22g2 connected to both sides of the snap-fit ​​part 22g1 and extending downward. The snap-fit ​​part 22g1 has hook-fit parts 22g4 extending outward from both sides for hooking with the other end of the rocker arm tension spring 22h. The two rocker arm parts 22g2 are rotatably connected to the rocker arm base 22a5 through the rocker arm shaft 22i. The structure reserved in the hook-fit part 22g4 is connected to the rocker arm tension spring 22h to ensure that the rocker arm tension spring 22h can apply a corresponding force to the rocker arm block 22g.

[0093] Furthermore, such as Figures 10-11 As shown, the reset block 22j and the stop block 22n are rotatably mounted between the two swing arms 22g2 via the reset shaft 22m and the stop shaft 22o, respectively. One end of the stop torsion spring 22p is hooked to the swing arm 22g2, and the other end of the stop torsion spring 22p abuts against the latching part 22g1. One end of the reset torsion spring 22k is hooked to the swing arm 22g2. Thus, the latching part 22g1 is designed to engage with the engaging part 23a, and the two swing arms 22g2 create a space between them, which facilitates the installation and movement of the stop block 22n and the reset block 22j.

[0094] In another embodiment of the invention, such as Figures 9-12As shown, the inner sides of the two swing arm portions 22g2 are respectively provided with opposing abutment portions 22g3. The upper end of the stop block 22n abuts against the abutment portion 22g3, and one end of the stop torsion spring 22p is hooked onto the abutment portion 22g3. The abutment portion 22g3 is configured to form an abutment engagement with the stop block 22n, limiting the stop block 22n from excessively rotating (e.g., rotating 360°) under the action of the stop shaft 22o. This ensures that the stop block 22n is restricted to the abutment portion 22g3 after rotating to a certain angle. When the force continues to be applied to the stop block 22n, the stop block 22n will transmit the force to the swing arm block 22g, causing the swing arm block 22g to rotate backward as a whole. This provides sufficient space for the resetting of the engagement portion 23a of the support arm 23.

[0095] In another embodiment of the invention, such as Figures 10-11 As shown in Figure 13, the gear block 22n includes a gear part 22j1 located at the lower end and gear arms 22j2 extending upward from both sides of the gear part 22j1. ​​The two gear arms 22j2 are rotatably connected between the two swing arm parts 22g2 via the gear pivot 22o, and the two gear arms 22j2 respectively abut against the two abutting parts 22g3. Specifically, the gear part 22j1 is provided for the engagement and positioning of the pressing part to form a second gear. The gear arms 22j2 are provided for the rotational installation of the gear and for the installation of the gear torsion spring 22p. They are also used to abut against the abutting parts 22g3. This structural design effectively achieves the cooperation with the abutting parts 22g3.

[0096] Furthermore, such as Figure 13 As shown, the bottom end of the gear shifting part 22j1 is provided with a gear shifting inclined surface 22j3 for engaging with the inclined surface of the reset block 22j. The gear shifting inclined surface 22j3 is provided with a gear shifting groove 22j4 for engaging with the engagement part 23a. This gear shifting inclined surface 22j3 can engage with the inclined surface of the reset block 22j; that is, when the gear shifting block 22n and the reset block 22j come into contact, they can slide relative to each other a certain distance based on this inclined surface engagement, ensuring that the two can work together without jamming. The gear shifting groove 22j4 on the gear shifting inclined surface 22j3 is used for engagement with the engagement part 23a, thus creating a second gear position at that location.

[0097] In another embodiment of the invention, such as Figures 10-11As shown in Figure 14, the reset block 22j includes a reset portion 22n1 located at the lower end and a rotating portion 22n2 extending upward from the reset portion 22n1. The rotating portion 22n2 is rotatably connected to the two swing arms 22g2 via the reset shaft 22m. The upper end of the reset portion 22n1 is provided with a reset inclined surface 22n3 that engages with the inclined surface of the stop inclined surface 22j3, and the lower end of the reset portion 22n1 is provided with a reset arc groove 22n4 for pre-positioning the engagement portion 23a. Specifically, the rotating portion 22n2 is provided for connection to the reset shaft 22m, thereby allowing the entire reset block 22j to rotate relative to the swing arm block 22g by an angle. The reset part 22n1 is designed to cooperate with the stop block 22n. When the engagement part 23a swings above the reset block 22j, it can continue to guide the engagement part 23a to swing downward until the engagement part 23a swings below the reset part 22n1. Then, the engagement part 23a swings upward in the opposite direction and abuts against the reset arc groove 22n4. At this time, a very weak positioning force is formed on the engagement part 23a, but it will not prevent the engagement part 23a from continuing to swing upward. Instead, it allows the user to clearly judge through this weak force that the engagement part 23a of the support arm 23 is about to reset to engage with the upper end of the swing arm block 22g, making it very comfortable to use.

[0098] Furthermore, such as Figure 3 and 7 As shown in Figures 8-8, the adjustment seat 22 in this embodiment also has a housing 24, which covers the base and is used to protect the other components of the adjustment seat 22.

[0099] like Figures 19-20 As shown, this embodiment of the invention also provides a head-mounted smart device, which includes a smart component 200 and the aforementioned Bluetooth headset 100. The side of the smart component 200 is provided with a main support 40 that cooperates with and connects to the headset bracket 30 of the headset body 10. The head-mounted smart device in this embodiment has a detachable and usable Bluetooth headset 100, forming an integrated head-mounted smart device that is convenient to use and carry.

[0100] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
