[0049] An embodiment of the utility model provides a kind of intelligent audio playing equipment, reference Figures 1 to 4 , comprising:

[0050] Sound box body 1;

[0051] Storage bin 2, be located in the sound box body 1, for receiving shoulder strap 3;

[0052] Shoulder strap 3, is stored in the storage bin 2, the first end of the shoulder strap 3 is connected in the storage bin 2;

[0053] Lock catch 4, with the sound box body 1 detachable connection, the lock catch 4 is connected with the second end of the shoulder strap 3;

[0054] Connecting piece 5, be located in the sound box body 1, the connecting piece 5 is used to be separably connected with the lock catch 4, to realize the detachable connection of the lock catch 4 with the sound box body 1.

[0055] The embodiment improves the shoulder strap 3 storage structure of existing intelligent sound box, by being provided with storage bin 2 on sound box body 1, so that shoulder strap 3 can be neatly stored when not being used, avoid the inconvenience of shoulder strap 3 scattering outside, improve the overall appearance and neatness of sound box. Storage bin 2 provides a safe storage space for shoulder strap 3, effectively prevents shoulder strap 3 from being exposed to external environment for a long time, reduces the risk of dirt and damage, thereby prolongs the service life of shoulder strap 3.

[0056] Meanwhile, one end of shoulder strap 3 is connected in storage bin 2, the other end of shoulder strap 3 is connected with lock catch 4, when needing to use shoulder strap 3, lock catch 4 is taken off from sound box body 1, so that shoulder strap 3 is pulled out, after shoulder strap 3 is pulled out, lock catch 4 is connected with connecting piece 5, i.e. shoulder strap 3 can form a ring for user to use, easy to operate, when not needing to use shoulder strap 3, it can be recycled in storage bin 2.

[0057] Further, in the embodiment, the other end of the shoulder strap 3 is connected with the lock piece 4, when the shoulder strap 3 is not used, the shoulder strap 3 and the lock piece 4 connected therewith can be stored in the storage bin 2 together, preventing the lock piece 4 from being exposed outside the sound box and damaged or lost, and further improving the flatness and neatness of the outside of the sound box body 1.

[0058] Further, the storage bin 2 is provided with a winding and unwinding mechanism 6, the first end of the shoulder strap 3 is connected with the winding and unwinding mechanism 6, and the winding and unwinding mechanism 6 is used for winding and unwinding the shoulder strap 3. In the embodiment, by providing the winding and unwinding mechanism 6 in the storage bin 2, automatic winding of the shoulder strap 3 is realized, the user can more conveniently control the winding and unwinding of the shoulder strap 3, without manually arranging the shoulder strap 3, and the shoulder strap 3 is prevented from being wound and knotted in the storage bin 2, which is more convenient in use and carrying, and improves the overall use experience of the user. When the shoulder strap 3 is completely wound into the storage bin 2, the appearance of the sound box is more simple, and no additional space is occupied.

[0059] In the embodiment, referring to Figure 5 , the winding and unwinding mechanism 6 includes an elastic reel 61, which is formed by winding a strip-shaped elastic metal strip, the inner end of the elastic reel 61 is fixed inside the storage bin 2, and the first end of the shoulder strap 3 is firmly bound or sewn on the outer end of the elastic reel 61. When the user needs to use the shoulder strap 3, the second end of the shoulder strap 3, i.e. the lock piece 4, can be manually pulled, at this time, the resistance of the elastic reel 61 needs to be overcome to pull the shoulder strap 3 out of the elastic reel 61. Once the lock piece 4 is connected with the connecting piece 5 on the sound box body 1, the shoulder strap 3 is fixed at the desired position. When the shoulder strap 3 is no longer needed, the user can unlock the lock piece 4 from the connecting piece 5, allowing the elastic force of the elastic reel 61 to automatically wind back the shoulder strap 3 and neatly store it in the storage bin 2.

[0060] Further, in order to ensure the safety and stability of the shoulder strap 3 during winding and unwinding, the storage bin 2 is further provided with an adjusting mechanism 7 for adjusting the length of the shoulder strap 3 extending out of the storage cavity, referring to Figure 6 , the adjusting mechanism 7 includes:

[0061] a sleeve 71 connected with the winding and unwinding mechanism 6 and rotating with the winding and unwinding mechanism 6, and a plurality of clamping teeth 72 are arranged at the end of the sleeve 71 in the rotating direction; in the 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, and the first end of the shoulder strap 3 is connected with the sleeve 71, so that the shoulder strap 3 can be wound on the sleeve 71 during the rotation of the sleeve 71 for winding and unwinding, achieving simple storage and extraction.

[0062] The locking assembly 73 is movably connected with the pawl 72, and the locking assembly 73 has a locking state and an unlocking state with the sleeve 71. In this embodiment, the locking assembly 73 is movably connected with the pawl 72 at the end of the sleeve 71. Specifically, under normal circumstances, the pawl 72 between the locking assembly 73 and the sleeve 71 is in a locked state, and the sleeve 71 cannot rotate, which can avoid the user from mistakenly pulling out the shoulder strap 3. When it is necessary to pull out the shoulder strap 3, the pawl 72 between the locking assembly 73 and the sleeve 71 is adjusted to an unlocked state, and the sleeve 71 can rotate, so that the shoulder strap 3 can be wound or unwound.

[0063] In this embodiment, by adjusting the sleeve 71 and the locking assembly 73 in the adjusting mechanism 7, the user can accurately control the length of the shoulder strap 3 extending out of the storage bin 2, realize the switching between the hand-carrying and shoulder-carrying modes, and meet the needs of the user in various use scenarios, so as to meet different carrying and use requirements. The connection structure between the locking assembly 73 and the sleeve 71 ensures the stability of the shoulder strap 3 at a fixed length, and avoids the length change caused by accidental pulling or shaking. The user experience is improved: the design of the adjusting mechanism 7 enables the user to easily and quickly adjust the length of the shoulder strap 3 without complex operations or additional tools, thereby improving the convenience and comfort of use.

[0064] Specifically, referring to Figure 6The locking assembly 73 comprises a push rod 731, the end of the push rod 731 abuts against a reset spring 732, the side wall of the push rod 731 is provided with a guide column 733, the outer side of the push rod 731 is sleeved with a sliding block 734, the sliding block 734 is provided with a guide groove 735 matched with the guide column 733, and the end of the sliding block 734 is used for clamping with the clamping tooth 72 to realize the state switching between the locking assembly 73 and the sleeve 71. Wherein, the end of the push rod 731 away from the reset spring 732 extends to the outer side of the sound box body 1, and is pressed by the user, when the user needs to pull out the shoulder strap 3 or recycle the shoulder strap 3, the user needs to unlock the locking assembly 73 and the sleeve 71, at this time, the user presses the push rod 731, and the push rod 731 moves towards the end of the reset spring 732, at this time, the reset spring 732 is compressed, the guide column 733 on the side wall of the push rod 731 moves towards the end of the reset spring 732, at this time, the guide column 733 slides along the guide groove 735, so that the sliding block 734 moves in the opposite direction of the push rod 731, so that the end of the sliding block 734 is separated from the clamping tooth 72, and the locking assembly 73 and the sleeve 71 are unlocked, at this time, the user can pull out the shoulder strap 3, or the shoulder strap 3 is automatically wound. When it is needed 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, the push rod 731 slides away from the reset spring 732 under the elastic restoring force of the reset spring 732, so that the sliding block 734 returns to the initial position under the relative movement force of the guide column 733 and the guide groove 735, and is clamped with the clamping tooth 72, so as to unlock the locking assembly 73 and the sleeve 71. The structure in the embodiment can realize the synchronous pressing of the push rod 731 before the winding and unwinding of the shoulder strap 3, which can effectively avoid the risk of damage of the shoulder strap 3 caused by the misoperation or the pulling of the shoulder strap 3 by children, and provides a safe unlocking button for the user.

[0065] It should be explained that, in addition to the above-mentioned mechanical elastic winding structure, the winding and unwinding mechanism 6 can also adopt an electric winding and unwinding structure. When the electric winding and unwinding structure is adopted, the drum can be driven to rotate by the motor, and one end of the drum is connected with the motor. The motor drives the drum to rotate in opposite directions, so that the shoulder strap 3 is wound around the drum in opposite directions, and the winding and unwinding of the shoulder strap 3 is realized.

[0066] In one embodiment, the connecting piece 5 can be protrudingly arranged outside the sound box body 1, or the connecting piece 5 can be recessedly arranged inside the sound box body 1. When the connecting piece 5 is protrudingly arranged outside the sound box body 1, two opposite protruding block structures can be arranged outside the sound box body 1, the connecting piece 5 is arranged on the opposite sides of the two protruding block structures, and the lock catch 4 is inserted between the two protruding block structures, so that the lock catch 4 and the connecting piece 5 are detachably connected.

[0067] In this embodiment, the connection member 5 is recessed in the speaker body 1, which can prevent the connection member 5 from being damaged during use and affect the appearance of the speaker. Figure 3 And Figure 4 The speaker body 1 is provided with a first slot 11, the connection member 5 is arranged beside the first slot 11, the lock member 4 is embedded in the first slot 11 and fixed in the first slot 11 through the connection member 5, and the first slot 11 is used for detachable connection with the lock member 4 when the lock member 4 drives the shoulder strap 3 to extend out of the storage compartment 2.

[0068] In this embodiment, when the shoulder strap 3 is pulled out and the lock member 4 needs to be fixed, the lock member 4 is directly inserted into the first slot 11 and connected with the connection member 5, which can prevent the lock member 4 from being damaged by external force and can also prevent the lock member 4 and the connection member 5 from being easily detached, causing the shoulder strap 3 to fall off and damage the speaker.

[0069] Further, the first slot 11 is designed to accommodate the lock member 4, and the edges of the first slot 11 are smoothly processed, which can be gripped by the user's hand during short-distance transportation of the speaker body 1 to avoid injury to the user's fingers during use. The first slot 11 is usually selected on the side or top of the speaker body 1 so that the user can easily insert and remove the lock member 4. In this embodiment, the first slot 11 is arranged on the side of the speaker body 1 and away from the storage compartment 2, so that the shoulder strap 3 can form an arc with a larger caliber after being pulled out, which is convenient for the user to carry and use.

[0070] Further, referring to Figure 7 The surface of the lock member 4 is provided with a clamping groove 41 for clamping the connection member 5, and the connection member 5 includes:

[0071] A clamping plate 51 movably arranged on the inner side wall of the first slot 11, and a first end of the clamping plate 51 is used for clamping the clamping groove 41;

[0072] A first elastic member 52 having one end abutting against a second end of the clamping plate 51 and the other end abutting against the speaker body 1.

[0073] The clamping plate 51 is further provided with a push plate 53, the push plate 53 is arranged on the surface of the speaker body 1, and the push plate 53 is used for driving the clamping plate 51 to move.

[0074] In the embodiment, when the locking piece 4 is installed in the first slot 11, the clamping groove 41 on the locking piece 4 is clamped with the end of the clamping plate 51, so as to lock the locking piece 4 in the first slot 11. Specifically, in the embodiment, the side of the clamping plate 51 close to the opening of the first slot 11 is provided as a guide slope. When the locking piece 4 is inserted into the first slot 11, the clamping plate 51 is pressed along the guide slope, so as to be pressed down, thereby facilitating the locking piece 4 to be completely inserted into the first slot 11. At this time, the first elastic member 52 is compressed. When the locking piece 4 is installed in place, the clamping groove 41 corresponds to the clamping plate 51. The clamping plate 51 is lifted and inserted into the clamping groove 41 under the elastic restoring force of the first elastic member 52, so as to clamp the clamping plate 51 with the clamping groove 41, thereby locking the locking piece 4 in the first slot 11. When it is needed to take out the locking piece 4, the user only needs to press the push plate 53, so as to drive the clamping plate 51 to be pressed down, thereby releasing the clamping force of the clamping plate 51 with the clamping groove 41, so as to facilitate the locking piece 4 to be taken out. At this time, the first elastic member 52 is compressed. When the locking piece 4 is taken out, the clamping plate 51 is lifted again under the elastic restoring force of the first elastic member 52. In the embodiment, the first elastic member 52 can be provided as a spring in the prior art. The number of the spring can be two, so as to ensure the stability of the lifting of the clamping plate 51.

[0075] Further, with reference to Figure 8 , the surface of the locking piece 4 is provided with a clamping groove 41 clamped with the connecting piece 5. The connecting piece 5 comprises:

[0076] a clamping column 54 movably arranged on the inner side wall of the first slot 11. The first end of the clamping column 54 is used to clamp with the clamping groove 41;

[0077] a second elastic member 55. One end of the second elastic member 55 abuts against the second end of the clamping column 54, and the other end of the second elastic member 55 abuts against the sound box body 1.

[0078] In the embodiment, when the locking piece 4 is installed in the first slot 11, the clamping groove 41 on the locking piece 4 is clamped with the end of the clamping column 54, so as to lock the locking piece 4 in the first slot 11. In particular, in the embodiment, the end of the clamping column 54 is provided in a hemispherical shape. During the process of inserting the locking piece 4 into the first slot 11, the clamping column 54 is pressed along the curved surface of the end of the clamping column 54, so as to press the clamping column 54 downward, prevent the clamping column 54 from being clamped with the clamping plate 51, and facilitate the locking piece 4 to be completely inserted into the first slot 11. At this time, the second elastic piece 55 is compressed. When the locking piece 4 is installed in place, the clamping groove 41 corresponds to the clamping column 54. The clamping column 54 is lifted and inserted into the clamping groove 41 under the elastic restoring force of the second elastic piece 55, so as to clamp the clamping column 54 with the clamping groove 41, and lock the locking piece 4 in the first slot 11. When it is needed to take out the locking piece 4, the user only needs to directly pull out the locking piece 4 with hands, so as to release the clamping force of the clamping column 54 with the clamping groove 41, thereby facilitating the taking out of the locking piece 4. At this time, the locking piece 4 will press the clamping column 54 downward again, and the second elastic piece 55 is compressed. When the locking piece 4 is taken out, the clamping column 54 will be lifted again under the elastic restoring force of the second elastic piece 55. In the embodiment, the second elastic piece 55 can be provided as a spring in the prior art, and the number of the spring can correspond to the number of the clamping column 54.

[0079] Further, with reference to Figure 1 and Figure 2 , the sound box body 1 is further provided with a second slot 12, which is used for detachable connection with the locking piece 4 when the shoulder strap 3 is stored in the storage bin 2.

[0080] In the embodiment, the second slot 12 can provide a space to accommodate the locking piece 4 after the shoulder strap 3 is completely stored back into the storage bin 2. When the shoulder strap 3 is no longer needed to be used and is wound back into the storage bin 2, the locking piece 4 will also move to a certain preset position of the sound box body 1. At this time, the user can connect the locking piece 4 with the second slot 12 through operation, so as to ensure that the locking piece 4 and the shoulder strap 3 can be stably fixed on the sound box body 1 when they are not used, and avoid being randomly shaken or lost. At the same time, the structure of the slot can completely hide the locking piece 4 on the sound box body 1, so that the smart sound box can still maintain the overall compactness and portability when the shoulder strap 3 is not needed.

[0081] Further, in the embodiment, the position of the second slot 12 is provided on one side of the side surface of the sound box body 1 close to the storage bin 2, so that when the locking piece 4 is taken out from the second slot 12, the shoulder strap 3 can be pulled out, the length of the shoulder strap 3 is saved, material waste is avoided, and cost is reduced.

[0082] Further, the contact surfaces between the locking piece 4 and the second slot 12 are both provided with anti-slip structures.

[0083] Alternatively, the lock piece 4 is in interference fit with the second slot 12, and the contact surface between the lock piece 4 and the second slot 12 is made of elastic material.

[0084] Alternatively, the lock piece 4 is connected with the second slot 12 through magnetic attraction structure.

[0085] In this embodiment, the stability of the connection between the lock piece 4 and the second slot 12 is ensured through the anti-slip structure or the interference fit structure, preventing the lock piece 4 from accidentally slipping off or falling off during use. Specifically, when using the anti-slip structure, raised anti-slip lines, anti-slip points or anti-slip grooves are provided on the surface of the lock piece 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, etc. The shape and distribution of the anti-slip lines can be designed according to actual needs to ensure that sufficient friction can be provided when the lock piece 4 is connected with the second slot 12, preventing the lock piece 4 from accidentally slipping off. Similarly, corresponding anti-slip structures such as anti-slip lines, anti-slip points 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 lock piece 4, further enhancing the stability of the connection.

[0086] When using the interference fit structure, the size of the lock piece 4 is slightly larger than the size of the second slot 12 to achieve interference fit. This structure makes the lock piece 4 need to overcome a certain resistance when inserted into the second slot 12, thereby ensuring the stability of the connection after. In order to reduce the difficulty of insertion caused by interference fit and increase the flexibility of connection, the contact surface of the lock piece 4 or the second slot 12 can be made of elastic material. For example, rubber, silicone or other elastic materials can be used to make the contact part of the lock piece 4 or the second slot 12. These elastic materials can deform when subjected to external force, making it easier to achieve interference fit between the lock piece 4 and the second slot 12.

[0087] When using the magnetic attraction structure, magnetic materials can be embedded in the lock piece 4 and the second slot 12, for example, magnets are installed in the lock piece 4 and the second slot 12 respectively, or magnets are installed in one of the lock piece 4 or the second slot 12, and the other structure corresponds to the installation of magnetic materials that can be magnetically attracted. In this way, when the lock piece 4 is inserted into the second slot 12, the two are attracted together directly through the magnetic attraction force of the magnet, completing the connection between the lock piece 4 and the second slot. When it is necessary to take out the lock piece 4, the user only needs to overcome the magnetic attraction force to pull it out, which is convenient and fast.
