The Bluetooth headset 1000 is better in wearing stability, is not easy to fall off, and is more suitable for sports scenes.

Specifically, since the ear wings 20 are protruded from the outer surface of the insertion portion 11, and the bluetooth headset 1000 is clamped on the user's ear by being matched with the clamping end 112, the friction between the bluetooth headset 1000 and the ear is enhanced, thereby effectively preventing the bluetooth headset 1000 from falling. In addition, the ear wings 20 and the clamping ends 112 are arranged opposite to each other in the first direction of the placement part 11, after the Bluetooth headset 1000 is clamped, the clamping ends 112 and the ear wings 20 are respectively arranged at two sides of the placement part 11 to support the Bluetooth headset 1000, so that the stress of the Bluetooth headset 1000 in the ear is more balanced, and the Bluetooth headset 1000 can be worn on the ear more firmly. And the earflap 20 is movably arranged in the mounting cavity 111, when the Bluetooth headset 1000 is worn, the earflap 20 can be adapted and fixed according to the size of the ear, and the Bluetooth headset 1000 has stronger adaptability.

In addition, the elastic locking assembly 30 provided in the bluetooth headset 1000 of the present application can lock the position of the wings 20 after they are retracted, thereby facilitating the storage of the bluetooth headset 1000, for example, facilitating its placement in a charging bin, and also enabling the charging bin to be smaller.

The shape of the insertion portion 11 is adapted to the ear so that the insertion portion 11 can be brought into sufficient contact with the ear. Illustratively, the shape of the insert 11 in the present application is pea-like; the pea-shaped insertion portion 11 is more closely contoured to the external auditory meatus, thereby making contact therewith more efficient.

Further, the placement portion 11 is further provided with a sound outlet 114, the sound outlet 114 is communicated with the outside, the placement portion 11 is further provided with an earphone unit 40, the earphone unit 40 is disposed opposite to the sound outlet 114, and preferably, the earphone unit 40 is close to the sound outlet 114, so as to provide a larger installation space for the ear wings 20.

In the present application, the housing 10 further includes the ear portion 12, the ear portion 12 is disposed on a side of the placement portion 11 away from the sound outlet 114, and the bluetooth headset 1000 can be more firmly fixed on the ear by the design of the ear portion, so as to reduce the risk of falling off during exercise. In particular, the ear stem 12 may provide additional support to enable the Bluetooth headset 1000 to more closely fit the ear. In this way, the Bluetooth headset 1000 is less prone to falling or loosening during running, exercise, or other strenuous exercise.

In addition, the ear stem 12 can provide a mounting space for accommodating a battery, a control button and a microphone, so as to reduce the space occupation of the components in the insertion portion 11, and facilitate the arrangement of the ear wings 20.

In the present application, the shape of the ear wing 20 is variously provided. Preferably, the side of the ear wing 20 exposed outside the through hole 113 has a half-arc surface, and the half-arc surface has a smoother outer contour, so that the comfort level of the user is better.

Referring to fig. 3-5, in one embodiment, the bluetooth headset 1000 further includes a slider 22 coupled to the ear wings 20, the slider 22 being movably disposed within the mounting cavity 111; the connection structure 21 is a track groove 221 formed on the sliding block 22 along a second direction (as shown in a Z direction in fig. 3), the second direction is perpendicular to the first direction, the track groove 221 includes a first limiting groove 2211, a first guiding groove 2212, a second limiting groove 2213, and a second guiding groove 2214, which are sequentially connected end to end, and the first limiting groove 2211 is located at a side of the second limiting groove 2213 away from the through hole 113.

The elastic locking assembly 30 comprises an elastic member 31 and a hooking member 32, wherein the elastic member 31 is arranged at one side of the sliding block 22 away from the through hole 113 in the first direction, and the hooking member 32 is partially accommodated in the track groove 221; when the elastic member 31 compresses and stores energy, the hooking member 32 can enter the second limiting groove 2213 from the first limiting groove 2211 by using the first guiding groove 2212, and when the elastic member 31 releases energy, the hooking member 32 can enter the first limiting groove 2211 from the second limiting groove 2213 by using the second guiding groove 2214. By the arrangement, the lug 20 has an unlocking position and a locking position, and cannot move after being locked, so that the reliability of the structure is better.

Specifically, the sliding block 22 is slidably connected to the mounting cavity 111, which may be integrally formed with or combined with the ear wing 20, the elastic member 31 is a spring, the elastic member 31 acts on the sliding block 22 and makes the sliding block 22 always move toward the through hole 113, and the track groove 221 cooperates with the hook holding member 32 and the elastic force of the elastic member 31 to limit the moving position of the sliding block 22, thereby limiting the moving position of the ear wing 20. The first and second limiting grooves 2211 and 2213 can better limit the sliding block 22 so as to keep the locking or unlocking position. In the process of alternately transferring the hooking member 32 between the first limiting groove 2211 and the second limiting groove 2213, the first guiding groove 2212 and the second guiding groove 2214 can limit the hooking member 32 and simultaneously guide the hooking member 32 to move into the first limiting groove 2211 or the second limiting groove 2213 more smoothly according to the preset path, so as to avoid the hooking member 32 from being blocked in the sliding process of the track groove 221.

Referring to fig. 4-5, in an embodiment, the second guide groove 2214 is located in a third direction (as shown in the Y direction in fig. 4) of the first guide groove 2212, and the third direction is perpendicular to the orientation of the through hole 113; the hooking member 32 is an elastic hooking member 32, which has a tendency to swing in a third direction for resetting; the hooking member 32 can elastically deform after being stressed and has elastic restoring capability, specifically, the original position of the hooking member 32 is located at one side of the track groove 221 in the third direction, and the hooking member 32 is accommodated in the track groove 221 to store a certain elastic potential energy, so that the hooking member 32 always has a swinging trend towards the third direction, the track groove 221 limits the elastic restoration of the hooking member 32, and when the hooking member 32 moves to each connection position of the track groove 221 in the third direction, the hooking member 32 can be more rapidly transferred from the first guide groove 2212 to the second limit groove 2213 or from the second limit groove 2213 to the second guide groove 2214 by virtue of the elastic potential energy. The present embodiment improves structural functional reliability by utilizing the characteristics of the hooking member 32 itself.

Referring to fig. 6, further, the second limiting groove 2213 includes an abutting portion 2213a, a front guide section 2213b and a rear guide section 2213c, one end of the front guide section 2213b is communicated with one end of the first guide groove 2212 away from the first limiting groove 2211, the other end of the front guide section 2213b extends toward a direction approaching the first limiting groove 2211 and the second guide groove 2214 and is communicated with the abutting portion 2213a, one end of the rear guide section 2213c is communicated with one end of the second guide groove 2214 away from the first limiting groove 2211, and the other end of the rear guide section 2213c extends toward a direction approaching the first limiting groove 2211 and the first guide groove 2212 and is communicated with the abutting portion 2213 a; the abutting portion 2213a locks the hooking member 32 at the locking position, the front guide segment 2213b and the rear guide segment 2213c are V-shaped, and the abutting portion 2213a is located at the bottom of the V-shape, so that the front guide segment 2213b and the rear guide segment 2213c can further limit the hooking member 32, and the hooking member is not easy to separate from the abutting portion 2213a, so that stability of the tab 20 at the locking position is improved.

Similarly, the first limiting groove 2211 includes a start segment 2211a and an end segment 2211b which are communicated, one end of the start segment 2211a is communicated with one end of the first guiding groove 2212 away from the second limiting groove 2213, the other end extends toward a direction away from the second limiting groove 2213, one end of the end segment 2211b is communicated with one end of the second guiding groove 2214 away from the second limiting groove 2213, the other end extends toward a direction away from the second limiting groove 2213, and a distance between the start segment 2211a and the end segment 2211b is gradually narrowed in a direction of the first limiting groove 2211 away from the second limiting groove 2213. Specifically, the start segment 2211a is V-shaped like the end segment 2211b to better limit the position of the hooking member 32 in the first limiting groove 2211, so as to keep the unlocking position unchanged.

In this embodiment, the front and rear segments 2213b and 2213c and the front and rear segments 2211a and 2211b can guide the hooking member 32 more precisely, so that the hooking member 32 moves into place.

Further, the starting section 2211a extends in a direction away from the through hole 113 and protrudes out of the end section 2211b, the protruding portion of the starting section 2211a forms a clamping portion, and the clamping portion has the same function as the abutting portion 2213a, and can also better limit the hooking piece 32 in the first limiting groove 2211, so that the sliding block 22 is in the unlocking position unchanged.

By implementing the embodiment, the user can unlock and lock by pressing the lug 20, and the operation feeling of the user is stronger. In order to better understand the technical effect, the following is exemplified by the working principle in the unlocking and locking application scenario. The user presses the tab 20 to retract against the elastic force of the elastic member 31, the hooking member 32 enters the leading segment 2213b of the second limiting groove 2213 from the first limiting groove 2211 by using the first guiding groove 2212, and slides from the leading segment 2213b to the abutment 2213a by using the characteristic of the hooking member 32 itself, thereby holding the tab 20 in the locking position. When unlocking is needed, the user only needs to press the tab 20 again, so that the hooking member 32 is transferred to the second guiding groove 2214 through the abutting portion 2213a, and then the elastic member 31 is used to release energy to return the tab 20 to the first limiting groove 2211, so that the tab 20 is in the unlocking position. Therefore, the Bluetooth headset 1000 is easy to unlock and lock, the user can quickly adjust the state of the ear wing 20 by pressing, and the time is saved and the unlocking and locking efficiency is greatly improved.

It should be noted that when the user presses the tab 20 to release from the locking position, the elastic member 31 is compressed to generate a repulsive force. This resilience gives the user a resilient feel that gives the user a clearer sense of the unlocking of the wings 20 and a better feel for the user.

Referring to fig. 7-8, in one embodiment, the leading segment 2213B is positioned adjacent to the first guide groove 2212 (as shown in position B in fig. 7) to a greater depth than the first guide groove 2212 is positioned adjacent to the leading segment 2213B (as shown in position a in fig. 7); the depth of the position of the second guide groove 2214 adjacent to the rear guide section 2213c (shown as the position F in fig. 7) is greater than the depth of the position of the rear guide section 2213c adjacent to the second guide groove 2214 (shown as the position E in fig. 7); the depth of the position (shown as position D in fig. 7) of the abutment portion 2213a adjacent to the leading segment 2213b is greater than the depth of the position (shown as position C in fig. 7) of the leading segment 2213b adjacent to the abutment portion 2213a, and the depth of the position (shown as position H in fig. 7) of the leading segment 2211a adjacent to the trailing segment 2211b is greater than the depth of the position (shown as position G in fig. 7) of the trailing segment 2211b adjacent to the leading segment 2211 a. By this arrangement, the hooking member 32 can be prevented from reversely retreating in the track groove 221, so that the hooking member 32 moves unidirectionally along the path of the track groove 221, and the reliability of the structure is ensured.

Specifically, the different depths of the front guide section 2213b and the first guide groove 2212, the rear guide section 2213c and the second guide groove 2214, the front guide section 2213b and the abutting portion 2213a, and the tail section 2211b and the starting section 2211a respectively form steps, and the blocking surface provided by the height difference formed by the steps can prevent the hooking piece 32 from retreating to the original position, so that the moving path of the hooking piece 32 is further limited, more accurate position control and operation are realized, and the phenomenon that locking or unlocking cannot be performed is avoided.

Referring to fig. 6, in one embodiment, the path length of the starting segment 2211a (shown as o in fig. 6) is 2.5mm or more and 3.5mm or less. By the arrangement, the telescopic space which can be freely adjusted when the lug 20 is pressed at the unlocking position is provided, ears with different sizes are matched, and wearing comfort of a user is improved. Illustratively, the path length of the starting segment 2211a may be set to 3mm in the present embodiment, so that the earflap 20 has a free telescopic space of 3mm in the unlocked state.

In addition, in this embodiment, since the pressing tab 20 enters the locked state, the hooking member 32 can be placed in the second limiting groove 2213 only through the first guiding groove 2212, and still requires a longer stroke when switching to the locked state in the freely telescopic state, so as to prevent accidental locking during wearing.

Preferably, an inclined plane is disposed at the connection area between the first guiding groove 2212 and the starting section 2211a, so that the hooking member 32 can only enter the first guiding groove 2212 from the starting section 2211a by pressing, and further accidental locking when the user wears the bluetooth headset 1000 is avoided. Therefore, the user cannot accidentally lock when wearing the bluetooth headset 1000, and the stability of the bluetooth headset 1000 is better.

Referring to fig. 9, in one embodiment, the catch 32 includes a swing section 321 and a fixed section 322; the fixed section 322 is fixedly arranged in the mounting cavity 111 and is positioned at one side of the sliding block 22 close to the through hole 113, one end of the swinging section 321 is in bending connection with the fixed section 322, and the other end extends towards the direction away from the through hole 113 and is hooked in the track groove 221. So configured, the swing section 321 has a tendency to move in a third direction, allowing for smooth transfer in the track groove 221, allowing for faster response when the tab 20 is unlocked and locked to switch.

Specifically, the hooking member 32 can be integrally bent and formed, which is convenient for manufacturing and assembling, one end of the hooking member 32 is hooked on the track groove 221, and the hooking member 32 is tightly attached to the groove walls of the first and second limiting grooves 2211 and 2213 in cooperation with the elastic force of the elastic member 31. The original position of the swing section 321 is located at one side, far away from the first guide groove 2212, of the second guide groove 2214 in the third direction, the swing section 321 is placed in the track groove 221, the swing section 321 swings and twists away from the original position relative to the fixed section 322, so that the swing section 321 generates elastic reset potential energy, and as the first guide groove 2212, the second limit groove 2213 and the second guide groove 2214 are sequentially arranged in the third direction, when the limit pieces move to the connecting position between every two of the limit pieces in the third direction, the limit pieces can be automatically shifted, and the situation that unlocking or locking is not in place is reduced.

Referring to fig. 10, in an embodiment, a receiving groove 222 is formed on a side of the sliding block 22 away from the through hole 113 in the first direction, a limiting post 1111 is formed on a wall of the mounting cavity 111, the limiting post 1111 extends toward a notch of the receiving groove 222, one end of the elastic member 31 is received in the receiving groove 222, and the other end is sleeved on the limiting post 1111. The limiting column 1111 is matched with the accommodating groove 222 so as to limit the elastic piece 31, and the elastic piece 31 is prevented from being pressed and twisted. Specifically, the elastic member 31 is a spring, the outer contour of the accommodating groove 222 may be adapted to the outer ring of the spring, and the outer contour of the limiting post 1111 may be adapted to the inner ring of the spring, so as to improve the limiting effect on the spring.

Referring again to fig. 10, in an embodiment, a guide block 223 is protruding from a side of the sliding block 22 facing away from the track groove 221, a guide groove 1112 is provided on a cavity wall of the mounting cavity 111, the guide groove 1112 extends in the first direction, and the guide block 223 is accommodated in the guide groove 1112. The guide block 223 is matched with the guide groove 1112 to provide positioning and guiding for the sliding block 22, so as to improve the sliding stability of the sliding block 22.

Referring to fig. 3, in an embodiment, a soft adhesive layer 23 is disposed on a side of the ear wing 20 exposed outside the through hole 113. The soft gel layer 23 is relatively soft and provides a soft touch when in contact with the ear.
