DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model is further described in detail with reference to the accompanying drawings.

[0024] See also Figure 1 - Figure 6 The utility model provides a portable speaker with a compact deformable structure, which includes a speaker 1, a bracelet 2 and a hand-held rod 3.

[0025] Among them, see Figure 1 - Figure 2The speaker 1 includes a main body 13, a speaker tube 14 is fixedly connected to the front end of the main body 13, a receiving groove 11 is opened at the rear end of the main body 13, and a mounting groove 12 is opened on the side wall of the receiving groove 11, and a mounting sleeve 17 is fixedly connected to the bottom of the main body 13, and a receiving hole is opened at the bottom of the main body 13, and the receiving hole is communicated with the inner wall of the mounting sleeve 17, and an avoidance groove 15 is opened at the lower end of the mounting sleeve 17, and the diameter of the avoidance groove 15 is larger than the inner diameter of the mounting sleeve 17, and the inner wall of the mounting sleeve 17 is opened with an internal thread 16, the bracelet 2 is hingedly connected to the mounting groove 12, and the bracelet 2 is stored in the storage groove 11 as a whole, and one end of the hand-held rod 3 passes through the mounting sleeve 17 and extends into the receiving hole and is stored in the receiving hole. By storing both the bracelet 2 and the hand-held rod 3 inside the speaker 1, the compactness of the speaker structure is improved, and at the same time, the problem that the bracelet 2 and the hand-held rod 3 are easily lost during non-use periods is solved.

[0026] It should be noted that the functional components of the speaker are all installed in the inner cavity of the main body 13, and the sound is played and amplified through the speaker tube 14.

[0027] For details, please refer to Figure 3 and Figure 4 In order to expand the applicable scope of the bracelet 2, the bracelet 2 includes two groups of semicircular rods 21, which are symmetrically arranged and enclosed in a circular ring. One end of the semicircular rod 21 is fixedly connected with an elastic extension rod 24, and the other end of the semicircular rod 21 is provided with a limited position slide groove 22. The elastic extension rod 24 extends into the other group of limited position slide grooves 22 away from the end of the semicircular rod 21 and is fixedly connected with a limited position block 23. The limit block 23 is slidably connected to the inner wall of the limit slide groove 22. The outer wall of one group of semicircular rods 21 is fixedly connected with a hinge block 25, and the hinge block 25 is hingedly connected in the installation groove 12. The semicircular rods 21 can be stored or moved out of the storage groove 11 by rotating around the hinge block 25. At the same time, the two groups of semicircular rods 21 can be pulled away from each other, and the elastic extension rod 24 can be partially moved out of the limiting slide groove 22, thereby extending the circumference of the bracelet 2. One group of semicircular rods 21 can also be rotated 180 degrees and placed parallel to the other group of semicircular rods 21, which can greatly reduce the circumference of the bracelet 2. The bracelet 2 can be worn on the wrist or upper arm as needed for easy carrying. The bracelet 2 can also be hung on branches with larger or smaller diameters to improve the applicability of the bracelet 2.

[0028] It should be noted that the elastic extension rod 24 is made of memory material and can automatically recover after the external force disappears, thereby driving the semicircular rod 21 to rotate and reset. By bringing the two groups of semicircular rods 21 close together, the elastic extension rod 24 can be pushed into the limiting slide groove 22 to complete the storage of the elastic extension rod 24, and twisting can be avoided to cause deformation of the elastic extension rod 24, making it difficult for the elastic extension rod 24 to be stored in the limiting slide groove 22.

[0029] It should also be noted that the limiting groove 22 includes an upper groove with a smaller diameter and a lower groove with a larger diameter. The upper groove is arranged near the end of the semicircular rod 21, and the upper groove is connected to the lower groove. The diameter of the limiting block 23 is consistent with the diameter of the lower groove, and the diameter of the elastic extension rod 24 is consistent with the diameter of the upper groove, so as to prevent the elastic extension rod 24 from falling off from the limiting groove 22 when the circumference of the bracelet 2 increases.

[0030] For details, please refer to Figure 5 In order to improve the comfort of using the hand-held rod 3, the hand-held rod 3 includes a mounting seat 31. Three groups of hinge grooves 33 are spaced apart at the lower end of the outer wall of the mounting seat 31. A support leg 34 is hingedly connected in the hinge groove 33. A fixing thread 32 is provided at the upper end of the outer wall of the mounting seat 31. The fixing thread 32 and the internal thread 16 can be selectively threadedly connected. By pulling the support leg 34 out of the lower end of the mounting sleeve 17 and threading the fixing thread 32 with the internal thread 16, the mounting seat 31 and the internal thread 16 are fixed, and the hand-held support leg 34 is convenient to use.

[0031] It should be noted that the three groups of support legs 34 are completely cylindrical when folded to improve the comfort when holding.

[0032] For details, please refer to Figure 6 The supporting leg 34 includes a curved prism 341, a mounting column 342 is fixedly connected to the top of the curved prism 341, the mounting column 342 is hingedly connected to the hinge slot 33, and anti-skid pads 343 are fixedly connected to both sides in contact with the hinge slot 33, a plurality of groups of anti-skid grooves 344 are spaced apart on the outer wall of the curved prism 341, a limiting thread 345 is provided at the lower end of the outer wall of the curved prism 341, and the limiting thread 345 is selectively threadedly connected to the internal thread 16, and the three groups of curved prisms 341 can be rotated outward by holding the curved prism 341, and the three groups of curved prisms 341 are distributed in a triangular shape to support the speaker, so that the speaker can be placed on a table or a flat area for use, and the three groups of curved prisms 341 can be folded and the folded curved prisms 341 can be held by hand for use, and the anti-skid grooves 344 prevent them from falling off during use. After use, rotate the curved prism 341 in the opposite direction to move the fixing thread 32 into the receiving hole and disengage from the internal thread 16, thereby pushing the curved prism 341 into the receiving hole until the limiting thread 345 moves to the lower end of the mounting sleeve 17, rotate the tail of the curved prism 341, and continue to rotate the curved prism 341 inward, so as to connect the limiting thread 345 with the internal thread 16 through the thread connection, so as to prevent the handle 3 from falling off from the receiving hole.

[0033] It should also be noted that when the arc-surface prism 341 is received in the receiving hole, the lower end of the arc-surface prism 341 is located in the avoiding groove 15 , and the bottom of the arc-surface prism 341 is flush with the lower end of the installation sleeve 17 .

[0034] Principle: In the storage state, the bracelet 2 is located in the storage groove 11, and the hand-held rod 3 is stored in the receiving hole. The semicircular rod 21 is rotated around the hinge block 25 to move the semicircular rod 21 to the outside of the storage groove 11, and the circular ring formed by the semicircular rod 21 and the elastic extension rod 24 is put on the wrist or upper arm for easy carrying. By moving the two groups of semicircular rods 21 away from each other and partially pulling the elastic extension rod 24 out of the limiting slide groove 22, the circumference of the circular ring can be adjusted, or one group of semicircular rods 21 can be twisted 180 degrees and placed parallel to the other group of semicircular rods 21, thereby greatly reducing the circumference of the ring sleeve. By rotating the tail ends of the three groups of arc-surface prisms 341 in the closed state, the limiting thread 345 is moved out of the lower end of the installation sleeve 17, and the lower end of the hand-held rod 3 is pulled out of the receiving hole. When the fixing thread 32 moves to the internal thread 16, the arc-surface prism 341 is rotated to make the fixing thread 3 2 is threadedly connected with the internal thread 16 to fix the mounting seat 31 inside the mounting sleeve 17, and the curved prism 341 in the closed state can be held for use, or the three groups of curved prisms 341 can be rotated in the direction away from the mounting seat 31 so that the tail ends of the three groups of curved prisms 341 are placed in a triangle to support the speaker 1, and the speaker 1 can be placed on a table or a flat position for use. After use, the three groups of curved prisms 341 are rotated in the direction close to the mounting seat 31, and the curved prisms 341 in the closed state are controlled to rotate in the opposite direction so that the fixing thread 32 is disengaged from the internal thread 16, and the hand-held rod 3 is pushed into the receiving hole until the lower end of the curved prism 341 is located in the avoiding groove 15, and the limiting thread 345 is threadedly connected with the internal thread 16 by rotating the lower end of the curved prism 341, so that the curved prism 341 is fixed to the inner wall of the mounting sleeve 17 to prevent the hand-held rod 3 from falling off from the receiving hole.
