[0012] Preferably, the card block is in the shape of a rectangular column, and the outer dimensions of the card block coincide with the inner dimensions of the card slot.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model can drive the accordion cover to extend and retract by lifting the lifting frame, and lock the lifting state of the lifting frame by a locking mechanism. When using the speaker, the lifting frame is lowered to expose the speaker sound hole. After use, the lifting frame is raised, and the outer side of the speaker is closed by the accordion cover, so that the speaker sound hole of the speaker can be dust-proof, and dust is prevented from blocking the speaker sound hole when the speaker is moved or placed. The retractable accordion cover can be used to expose or cover the speaker sound hole, so as to prevent the speaker from dust.

[0015] 2. In the utility model, when the lifting frame needs to be lifted, the pull rod drives the card block to overcome the spring elastic force and move out of the card slot, and then the lifting frame is lifted to control the extension and retraction of the accordion cover. When the lifting frame moves to the top or bottom to align the card block with another card slot, the spring pushes the card block to insert into the card slot, and the lifting frame is fixedly connected to the speaker. The lifting state of the lifting frame can be fixed by the provided locking mechanism, and then the extension and retraction state of the accordion cover can be locked.

[0020] 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.

[0021] Example:

[0022] See also Figures 1 to 3 The utility model provides a technical solution: a portable speaker that is easy to carry, including a base 1, a speaker 2 is installed on the top of the base 1, and a speaker sound outlet 6 is arranged in front of the middle of the speaker 2, wherein,

[0023] A lifting frame 7 is sleeved on the outer side of the speaker 2, and guide grooves 8 are symmetrically opened on both sides of the speaker 2. A guide block 9 is fixedly connected to the inner side of the lifting frame 7 corresponding to the guide groove 8;

[0024] An accordion cover 10 is installed between the lifting frame 7 and the base 1. The accordion cover 10 is sleeved on the outside of the speaker 2. The lifting frame 7 is locked in its lifting state by a locking mechanism.

[0025] By lifting and lowering the lifting frame 7, the accordion cover 10 can be driven to retract and retract, and the lifting state of the lifting frame 7 can be locked by the locking mechanism. When the audio system 2 is in use, the lifting frame 7 is lowered to expose the speaker sound hole 6. After use, the lifting frame 7 is raised, and the outer side of the audio system 2 is sealed by the accordion cover 10, so that the speaker sound hole 6 of the audio system 2 can be dust-proofed to prevent dust from blocking the speaker sound hole 6 when the audio system is moved or placed. The retractable accordion cover 10 can be used to expose or cover the speaker sound hole 6, so as to prevent the audio system 2 from dust.

[0026] See also Figures 1 to 3 Universal wheels 3 are symmetrically installed at the four corners of the bottom of the base 1, an armrest 4 is installed on the top of the speaker 2, a control panel 5 is arranged in front of the top of the speaker 2, a lifting frame 7 is frame-shaped, and the inner size of the lifting frame 7 is consistent with the outer size of the speaker 2. The speaker 2 is pushed or pulled by the armrest 4 to move the speaker 2 through the universal wheels 3, and various functions of the speaker 2 can be controlled through the control panel 5.

[0027] See also Figures 1 to 3The engaging mechanism includes a card slot 11. The inner walls of the upper and lower sides of the guide slot 8 are symmetrically provided with card slots 11. A card block slot 12 is provided on one side of the guide block 9 corresponding to the card slot 11. The lifting frame 7 is connected to a pull rod slot 13 on the outer side of the card block slot 12. A spring 14 is installed in the card block slot 12. A card block 15 is installed on the opening side of the spring 14 close to the card block slot 12. A pull rod 16 is fixedly connected to the side of the card block 15 close to the pull rod slot 13. The card block 15 is in the shape of a rectangular column, and the outer dimensions of the card block 15 are consistent with the inner dimensions of the card slot 11. When needed, When the lifting frame 7 is lifted or lowered, the pull rod 16 drives the block 15 to overcome the elastic force of the spring 14 and move out of the slot 11. Then the lifting frame 7 is lifted or lowered to control the extension and retraction of the accordion cover 10. When the lifting frame 7 moves to the top or bottom to align the block 15 with another slot 11, the spring 14 pushes the block 15 to insert into the slot 11, and the lifting frame 7 is fixedly connected to the speaker 2. The lifting state of the lifting frame 7 can be fixed by the provided locking mechanism, and then the extension and retraction state of the accordion cover 10 can be locked.

[0028] Working principle: This portable speaker is easy to carry. By lifting and lowering the lifting frame 7, the accordion cover 10 can be driven to extend and retract, and the lifting state of the lifting frame 7 is locked by a locking mechanism. When the speaker 2 is in use, the lifting frame 7 is lowered to expose the speaker sound hole 6. After use, the lifting frame 7 is raised, and the outer side of the speaker 2 is sealed by the accordion cover 10, so that the speaker sound hole 6 of the speaker 2 can be dust-proof, so that dust does not block the speaker sound hole 6 when the speaker is moved or placed. The retractable accordion cover 10 can be used to expose or cover the speaker sound hole 6, so as to prevent the speaker 2 from dust.

[0029] The speaker 2 is pushed or pulled by the armrest 4 to move the speaker 2 through the universal wheels 3, and the various functions of the speaker 2 can be controlled through the control panel 5. When the lifting frame 7 needs to be lifted or lowered, the pull rod 16 drives the block 15 to overcome the elastic force of the spring 14 and move out of the slot 11, and then the lifting frame 7 is lifted or lowered to control the extension and retraction of the accordion cover 10. When the lifting frame 7 moves to the top or bottom to align the block 15 with another slot 11, the spring 14 pushes the block 15 to insert into the slot 11, and the lifting frame 7 is fixedly connected to the speaker 2. The lifting state of the lifting frame 7 can be fixed by the provided locking mechanism, and then the extension and retraction state of the accordion cover 10 can be locked.
