[0049] One embodiment of the present invention provides a smart audio playback device with an adjustable shoulder strap, see reference. Figures 1 to 4 ,include:

[0050] Speaker body 1;

[0051] Storage compartment 2, located on the speaker body 1, is used to store the shoulder strap 3;

[0052] The shoulder strap 3 is stored in the storage compartment 2, and the first end of the shoulder strap 3 is connected to the storage compartment 2;

[0053] The fastener 4 is detachably connected to the speaker body 1, and the fastener 4 is connected to the second end of the shoulder strap 3;

[0054] Connector 5 is provided on the speaker body 1. Connector 5 is used to be detachably connected to the locking member 4 so as to realize the detachable connection between the locking member 4 and the speaker body 1.

[0055] This embodiment improves the existing smart speaker's shoulder strap 3 storage structure. By setting a storage compartment 2 on the speaker body 1, the shoulder strap 3 can be neatly stored when not in use, avoiding the inconvenience of the shoulder strap 3 being scattered outside and improving the overall aesthetics and neatness of the speaker. The storage compartment 2 provides a safe storage space for the shoulder strap 3, effectively preventing the shoulder strap 3 from being exposed to the external environment for a long time, reducing the risk of dirt and damage, thereby extending the service life of the shoulder strap 3.

[0056] Meanwhile, one end of the shoulder strap 3 is connected to the storage compartment 2, and the other end of the shoulder strap 3 is connected to the buckle 4. When the shoulder strap 3 is needed, the buckle 4 is removed from the speaker body 1, thereby pulling out the shoulder strap 3. After the shoulder strap 3 is pulled out, the buckle 4 is connected to the connector 5, so that the shoulder strap 3 can form a ring for the user to use. The operation is simple. When the shoulder strap 3 is not needed, it can be simply recycled back into the storage compartment 2.

[0057] Furthermore, in this embodiment, the other end of the shoulder strap 3 is connected to the buckle 4. When the shoulder strap 3 is not in use, the shoulder strap 3 and the buckle 4 connected to it can be stored together in the storage compartment 2 to prevent the buckle 4 from being exposed to the outside of the speaker and damaged or lost. At the same time, it can further improve the flatness and neatness of the outside of the speaker body 1.

[0058] Furthermore, a winding / unwinding mechanism 6 is provided within the storage compartment 2. The first end of the shoulder strap 3 is connected to the winding / unwinding mechanism 6, which is used to wind and unwind the shoulder strap 3. In this embodiment, by providing the winding / unwinding mechanism 6 within the storage compartment 2, automatic winding of the shoulder strap 3 is achieved. Users can more conveniently control the winding and unwinding of the shoulder strap 3 without manually tidying it up, and the shoulder strap 3 is prevented from becoming tangled or knotted within the storage compartment 2. This makes it more convenient to use and carry, improving the overall user experience. When the shoulder strap 3 is completely wound into the storage compartment 2, the speaker's appearance is more streamlined and does not occupy additional space.

[0059] In this embodiment, reference Figure 5 The retraction mechanism 6 includes an elastic roller 61, which is formed by winding a strip of elastic metal. The inner end of the elastic roller 61 is fixed inside the storage compartment 2, and the first end of the shoulder strap 3 is securely bound or sewn to the outer end of the elastic roller 61. When the user needs to use the shoulder strap 3, they can manually pull the second end of the shoulder strap 3, i.e., the buckle 4. At this time, the resistance of the elastic roller 61 needs to be overcome to pull the shoulder strap 3 off the elastic roller 61. Once the buckle 4 is connected to the connector 5 on the speaker body 1, the shoulder strap 3 is fixed in the desired position. When the shoulder strap 3 is no longer needed, the user can unlock the buckle 4 and the connector 5, allowing the elastic force of the elastic roller 61 to automatically retract the shoulder strap 3 and neatly store it in the storage compartment 2.

[0060] Furthermore, to ensure the safety and stability of the shoulder strap 3 during the winding and unwinding process, an adjustment mechanism 7 is also provided inside the storage compartment 2. The adjustment mechanism 7 is used to adjust the length of the shoulder strap 3 extending out of the storage compartment. (Refer to...) Figure 6 The adjustment mechanism 7 includes:

[0061] The sleeve 71 is connected to the winding and unwinding mechanism 6 and rotates with the winding and unwinding mechanism 6. The end of the sleeve 71 is provided with several locking teeth 72 in the direction of rotation. In this embodiment, the sleeve 71 is coaxially installed on the outside of the winding and unwinding mechanism 6 and can rotate with the winding and unwinding mechanism 6. By connecting the first end of the shoulder strap 3 to the sleeve 71, the shoulder strap 3 can be wound around the sleeve 71 for winding and unwinding during the rotation of the sleeve 71, so as to achieve simple storage and extraction.

[0062] The locking component 73 is movably engaged with the locking tooth 72, and the locking component 73 and the sleeve 71 have a locked state and an unlocked state. In this embodiment, the locking component 73 is movably engaged with the locking tooth 72 at the end of the sleeve 71. Specifically, under normal circumstances, the locking tooth 72 between the locking component 73 and the sleeve 71 is in the locked state, and the sleeve 71 cannot rotate, which can prevent the user from accidentally pulling out the shoulder strap 3. When it is necessary to pull out the shoulder strap 3, simply adjust the locking component 73 and the sleeve 71 to the unlocked state, and the sleeve 71 can rotate, thereby realizing the winding and unwinding of the shoulder strap 3.

[0063] In this embodiment, by adjusting the sleeve 71 and locking component 73 in the adjustment mechanism 7, the user can precisely control the length of the shoulder strap 3 extending out of the storage compartment 2, enabling switching between hand-carrying and shoulder-carrying methods to meet the user's needs in various usage scenarios, thus satisfying different carrying and usage requirements. The snap-fit ​​structure between the locking component 73 and the sleeve 71 ensures the stability of the shoulder strap 3 at a fixed length, avoiding length changes caused by accidental pulling or shaking. Enhanced user experience: The design of the adjustment mechanism 7 allows users to easily and quickly adjust the length of the shoulder strap 3 without complicated operations or additional tools, thereby improving ease of use and comfort.

[0064] Specifically, refer to Figure 6The locking assembly 73 includes a push rod 731, with a return spring 732 abutting at the end of the push rod 731. A guide post 733 is provided on the side wall of the push rod 731, and a slider 734 is sleeved on the outside of the push rod 731. A guide groove 735 adapted to the guide post 733 is provided on the slider 734, and the end of the slider 734 is used to engage with the locking teeth 72 to realize the state switching between the locking assembly 73 and the sleeve 71. The push rod 731 extends to the outside of the speaker body 1 at the end away from the return spring 732, for the user to press. When the user needs to pull out or retract the shoulder strap 3, the locking component 73 and the sleeve 71 need to be unlocked. At this time, the user presses the push rod 731, causing the push rod 731 to move toward the end of the return spring 732. At this time, the return spring 732 is compressed, and the guide post 733 on the side wall of the push rod 731 moves toward the end of the return spring 732. At this time, the guide post 733 slides along the guide groove 735, causing the slider 734 to move in the opposite direction of the push rod 731, thereby separating the end of the slider 734 from the locking tooth 72, realizing the unlocking of the locking component 73 and the sleeve 71. At this time, the user can pull out the shoulder strap 3 or allow the shoulder strap 3 to automatically rewind. When it is necessary to stop the winding and unwinding operation of the shoulder strap 3, the user only needs to release the pushing force on the push rod 731. Under the elastic restoring force of the return spring 732, the push rod 731 slides away from the return spring 732. Thus, under the relative motion force of the guide post 733 and the guide groove 735, the slider 734 returns to its initial position and engages with the locking tooth 72, unlocking the locking component 73 from the sleeve 71. In this embodiment, this structure requires the push rod 731 to be pressed simultaneously before winding and unwinding the shoulder strap 3. This effectively avoids the risk of accidental operation or children pulling on the shoulder strap 3, causing damage, and provides a safe unlocking button for the user.

[0065] It should be noted that, in addition to the mechanical elastic winding structure described above, the winding and unwinding mechanism 6 can also adopt an electric winding and unwinding structure. When an electric winding and unwinding structure is adopted, the roller can be rotated by a motor. Simply connect one end to the roller, and the motor drives the roller to perform forward and reverse rotation, causing the shoulder strap 3 to rotate around the roller in a true reverse direction, thereby realizing the winding and unwinding of the shoulder strap 3.

[0066] In one embodiment, the connector 5 can protrude from the outside of the speaker body 1, or the connector 5 can be recessed into the inside of the speaker body 1. When the connector 5 protrudes from the outside of the speaker body 1, two opposing protrusion structures can be provided on the outside of the speaker body 1, the connector 5 is provided on the opposite sides of the two protrusion structures, and the locking member 4 is inserted between the two protrusion structures, so that the locking member 4 and the connector 5 can be detachably connected.

[0067] In this embodiment, since exposing the connector to the outside of the speaker would affect the speaker's aesthetics and make it susceptible to damage during use, the connector 5 can be recessed into the speaker body 1. (Refer to...) Figure 3 and Figure 4 The speaker body 1 is provided with a first slot 11, the connector 5 is provided on the side of the first slot 11, and the locking fastener 4 is embedded in the first slot 11 and fixed in the first slot 11 by the connector 5. The first slot 11 is used to detachably connect with the locking fastener 4 when the locking fastener 4 drives the shoulder strap 3 to extend from the storage compartment 2.

[0068] In this embodiment, by setting the first slot 11, when the shoulder strap 3 is pulled out and the fastener 4 needs to be fixed, it is directly inserted into the first slot 11 and connected to the connector 5, and will not be exposed outside the speaker, ensuring the overall flatness and aesthetics, preventing the fastener 4 from being damaged by external force, and also preventing the fastener 4 from easily loosening from the connector 5, causing the shoulder strap 3 to fall off and damage the speaker.

[0069] Furthermore, the first slot 11 is designed in shape and size to accommodate the locking element 4. The edges of the first slot 11 are rounded to allow the user to grip it during short-distance transport of the speaker body 1, thus preventing injury to the user's fingers during use. The first slot 11 is typically located on the side or top of the speaker body 1 to facilitate easy insertion and removal of the locking element 4 by the user. In this embodiment, the first slot 11 is located on the side of the speaker body 1, away from the storage compartment 2. This allows the shoulder strap 3 to extend and form a larger arc shape, making it convenient for the user to carry and use.

[0070] Further, refer to Figure 7 The surface of the locking member 4 is provided with a groove 41 for engaging with the connecting member 5, and the connecting member 5 includes:

[0071] A card plate 51 is movably inserted through the inner sidewall of the first slot 11, and the first end of the card plate 51 is used to engage with the slot 41.

[0072] The first elastic member 52 has one end abutting against the second end of the card plate 51, and the other end abutting against the speaker body 1.

[0073] The card plate 51 is also provided with a toggle plate 53, which passes through the surface of the speaker body 1 and is used to drive the card plate 51 to move.

[0074] In this embodiment, when the locking member 4 is installed in the first slot 11, the slot 41 on the locking member 4 engages with the end of the locking plate 51, thereby locking the locking member 4 in the first slot 11. Specifically, in this embodiment, the side of the locking plate 51 near the opening of the first slot 11 is set as a guide slope. When the locking member 4 is inserted into the first slot 11, it will squeeze the locking plate 51 along the guide slope, thereby pressing the locking plate 51 down, so that the locking member 4 can be completely inserted into the first slot 11. At this time, the first elastic member 52 is compressed. When the locking member 4 is installed in place, the slot 41 corresponds to the locking plate 51. The locking plate 51 rises under the elastic restoring force of the first elastic member 52 and inserts into the slot 41, realizing the engagement of the locking plate 51 and the slot 41, locking the locking member 4 in the first slot 11. When it is necessary to remove the locking element 4, the user only needs to press the actuating plate 53 by hand, causing the locking plate 51 to press down, releasing the locking force between the locking plate 51 and the locking slot 41, thus facilitating the removal of the locking element 4. At this time, the first elastic element 52 is compressed. After the locking element 4 is removed, the locking plate 51 will rise again under the elastic restoring force of the first elastic element 52. In this embodiment, the first elastic element 52 can be set as a spring in the prior art, and the number of springs can be set to two to ensure the stability of the lifting and lowering of the locking plate 51.

[0075] Further, refer to Figure 8 The surface of the locking member 4 is provided with a groove 41 for engaging with the connecting member 5, and the connecting member 5 includes:

[0076] The locking post 54 is movably inserted through the inner sidewall of the first slot 11, and the first end of the locking post 54 is used to engage with the slot 41.

[0077] The second elastic member 55 has one end abutting against the second end of the locking post 54, and the other end abutting against the speaker body 1.

[0078] In this embodiment, when the locking member 4 is installed in the first slot 11, the slot 41 on the locking member 4 engages with the end of the locking post 54, thereby locking the locking member 4 in the first slot 11. Specifically, in this embodiment, the end of the locking post 54 is set to be hemispherical. When the locking member 4 is inserted into the first slot 11, it will squeeze the locking post 54 along the curved surface of the end of the locking post 54, thereby pressing the locking post 54 down to prevent the locking post 54 from jamming with the locking plate 51, so that the locking member 4 can be completely inserted into the first slot 11. At this time, the second elastic member 55 is compressed. When the locking member 4 is installed in place, the locking member 4 engages with the locking post 54. The slot 41 corresponds to the locking pin 54. The locking pin 54 rises under the elastic restoring force of the second elastic element 55 and inserts into the slot 41, thus engaging the locking pin 54 with the slot 41 and locking the locking member 4 within the first slot 11. When the locking member 4 needs to be removed, the user simply pulls it out by hand, releasing the engagement between the locking pin 54 and the slot 41, facilitating its removal. At this time, the locking member 4 will press the locking pin 54 down again, compressing the second elastic element 55. After the locking member 4 is removed, the locking pin 54 will rise again under the elastic restoring force of the second elastic element 55. In this embodiment, the second elastic element 55 can be a spring as in the prior art, and the number of springs can correspond to the number of locking pins 54.

[0079] Further, refer to Figure 1 and Figure 2 The speaker body 1 is also provided with a second slot 12, which is used to detachably connect with the locking buckle 4 when the shoulder strap 3 is stored in the storage compartment 2.

[0080] In this embodiment, the second slot 12 provides a space to accommodate the locking element 4 after the shoulder strap 3 is completely stored in the storage compartment 2. When the shoulder strap 3 is no longer needed and is rolled up and stored in the storage compartment 2, the locking element 4 will also move to a preset position on the speaker body 1. At this time, the user can connect the locking element 4 to the second slot 12, thereby ensuring that the locking element 4 and the shoulder strap 3 can be securely fixed to the speaker body 1 when not in use, preventing them from shaking or being lost. At the same time, the slotted structure allows the locking element 4 to be completely hidden on the speaker body 1, so that the smart speaker can still maintain its overall compactness and portability when the shoulder strap 3 is not needed.

[0081] Furthermore, in this embodiment, the second slot 12 is located on the side of the speaker body 1 near the storage compartment 2, so that when the fastener 4 is removed from the second slot 12, the shoulder strap 3 can be pulled out, saving the length of the shoulder strap 3, avoiding material waste, and reducing costs.

[0082] Furthermore, anti-slip structures are provided on the contact surfaces between the locking element 4 and the second slot 12;

[0083] Alternatively, the locking element 4 is press-fitted into the second slot 12, and the contact surface between the locking element 4 and the second slot 12 is made of an elastic material.

[0084] Alternatively, the locking element 4 and the second slot 12 can be magnetically connected.

[0085] In this embodiment, an anti-slip structure or an interference fit structure is used to ensure the stability of the connection between the locking element 4 and the second slot 12, preventing the locking element 4 from accidentally slipping or falling off during use. Specifically, when an anti-slip structure is used, raised anti-slip textures, anti-slip dots, or anti-slip grooves are provided on the surface of the locking element 4, especially in the area in contact with the second slot 12. These anti-slip structures can be formed by molding, machining, or laser engraving. The shape and distribution of the anti-slip textures can be designed according to actual needs to ensure sufficient friction when the locking element 4 is connected to the second slot 12, preventing the locking element 4 from accidentally slipping off. Similarly, corresponding anti-slip structures, such as anti-slip textures, anti-slip dots, or anti-slip protrusions, can also be provided on the inner wall of the second slot 12. These structures can match the anti-slip structures on the locking element 4 to further enhance the stability of the connection.

[0086] When using an interference fit structure, ensure that the size of the locking element 4 is slightly larger than the size of the second slot 12 to achieve the interference fit. This structure requires the locking element 4 to overcome a certain resistance when inserted into the second slot 12, thus ensuring the stability of the connection. To reduce the insertion difficulty caused by the interference fit and increase the flexibility of the connection, the contact surface of the locking element 4 or the second slot 12 can be made of an elastic material. For example, rubber, silicone, or other elastic materials can be used to make the contact part of the locking element 4 or the second slot 12. These elastic materials can deform under external force, making it easier to achieve an interference fit between the locking element 4 and the second slot 12.

[0087] When a magnetic structure is used, magnetic materials can be embedded in the locking fastener 4 and the second slot 12. For example, magnets can be installed in the locking fastener 4 and the second slot 12 respectively, or a magnet can be installed in one structure of the locking fastener 4 or the second slot 12, and a magnetic material that can be magnetically attracted can be installed in the other structure. In this way, when the locking fastener 4 is inserted into the second slot 12, the two are directly attracted together by the magnetic attraction force, completing the connection between the locking fastener 4 and the second slot. When the locking fastener 4 needs to be removed, the user only needs to overcome the magnetic attraction force to pull it out, which is convenient and quick. Furthermore, the first slot 11 and the second slot 12 are symmetrically arranged on both sides of the speaker body 1, and the second end of the shoulder strap 3 passes through the storage compartment 2 and the second slot 12 in sequence and then connects to the locking fastener 4.

[0088] In this embodiment, the first slot 11 is located on the side away from the storage compartment 2, while the second slot 12 is located on the side closer to the storage compartment 2. (Refer to...) Figure 2 After the shoulder strap 3 is stored in the storage compartment 2, the locking buckle 4 is installed in the second slot 12 near the storage compartment 2, for reference. Figure 4 When the shoulder strap 3 extends, the locking buckle 4 is installed in the first slot 11 away from the storage compartment 2. The shoulder strap 3 forms an arc between the two symmetrical sides of the speaker body 1, making it convenient for users to carry and use. The design of the second end of the shoulder strap 3 passing through the storage compartment 2 and the second slot 12 in sequence before connecting with the locking buckle 4 makes the storage and unfolding process of the shoulder strap 3 smoother and more convenient, allowing users to complete the operation without effort.
