[0002] A speaker is a transducer that converts electrical signals into sound signals. The performance of the speaker has a great impact on the sound quality. The speaker is the weakest component in the audio equipment, but it is also the most important component for the sound effect.

[0003] When some of the current dual-magnetic-circuit speakers with inner and outer magnetic rings are installed, their diaphragms, folding rings and other components are usually directly exposed to the air. When the speakers are idle, dust and debris in the air can easily accumulate or collide with the diaphragm and folding ring, causing contamination to the diaphragm and folding ring, and may even cause the diaphragm and folding ring to break, affecting the use of the speaker.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a dual-magnetic circuit speaker with inner and outer magnetic ring spacing is provided, in order to achieve a more practical purpose. Utility Model Content

[0029] Among them, the pin assembly includes four second slide grooves 11, and the four second slide grooves 11 are equidistantly arranged on the circumferential side of the annular slide groove 4. A second slider 12 is slidably installed in the second slide groove 11. The second slider 12 is provided with a spherical protrusion on one side located in the annular slide groove 4. A plurality of tension springs 13 are installed on the circumferential side of the second slider 12, and the other end of the tension spring 13 is connected to one side of the second slide groove 11. When the protective cover 5 is installed to one side of the dual-magnetic circuit speaker body 2, the staff first inserts the annular block 6 into the annular slide groove 4. At this time, the second slider 12 is lifted by the annular block 6 and slides into the second slide groove 11, and then the protective cover 5 is rotated. When the position of the second slider 12 is aligned with the position of the groove 7, the second slider 12 is no longer limited by the annular block 6. Under the action of the rebound of the tension spring 13, it is inserted into the groove 7 to fix the protective cover 5.

[0030] The second sliding block 12 is engaged and connected with the groove 7 .

[0031] Among them, a screw rod 14 is rotatably installed in the installation groove 8, and the screw rod 14 passes through the front and rear sides of the connecting plate 10 and is threadedly connected to the connecting plate 10. Through the rotation of the screw rod 14, under the limiting action of the installation groove 8 and the chassis 1, the connecting plate 10 drives the U-shaped slider 9 to move on one side of the chassis 1, so that the U-shaped slider 9 extends from the side of the chassis 1 where the dual-magnetic circuit speaker body 2 is installed, thereby protecting the dual-magnetic circuit speaker body 2.

[0032] A motor 15 is installed on one side of the bottom end of the installation groove 8, and the output end of the motor 15 is transmission-connected to the screw rod 14 through a coupling. The motor 15 drives the screw rod 14 to rotate, thereby driving the connecting plate 10 to move.

[0033] A handle 16 is installed on the top of the chassis 1 to facilitate carrying the speaker.

[0034] Among them, casters 17 are installed at the four corners of the bottom end of the chassis 1 to facilitate the movement of the speaker.

[0035] The working principle of this embodiment is as follows: when the speaker needs to be used, the staff first rotates the protective cover 5 so that the annular block 6 on one side of the protective cover 5 lifts the second slider 12, so that the second slider 12 moves into the second slide groove 11 and disengages from the groove 7, and the protective cover 5 can be removed. When the protective cover 5 needs to be reinstalled, the staff first inserts the annular block 6 into the annular slide groove 4. At this time, the second slider 12 is lifted by the annular block 6 and slides into the second slide groove 11, and then the protective cover 5 is rotated. When the position of the second slider 12 is aligned with the position of the groove 7, the second slider 12 is no longer Under the limiting effect of the annular block 6, under the effect of the rebound of the tension spring 13, it is stuck in the groove 7 to fix the protective cover 5. When the staff uses the speaker outdoors, the motor 15 can be turned on according to the weather conditions. The motor 15 drives the screw 14 to rotate. Under the limiting effect of the installation groove 8 and the chassis 1, the connecting plate 10 drives the U-shaped slider 9 to move on one side of the chassis 1, so that the U-shaped slider 9 extends from the side of the chassis 1 where the dual-magnetic circuit speaker body 2 is installed, so as to protect the dual-magnetic circuit speaker body 2. After use, turn on the motor 15 and retract the U-shaped slider 9.
