[0023] The following is a detailed description of a speaker that is easy to assemble according to the present invention in conjunction with the accompanying drawings.

[0024] like Figure 1-3 As shown, an embodiment of the utility model of a speaker that is easy to assemble includes a supporting frame 1 and a diaphragm 2 arranged on the top of the supporting frame 1. The supporting frame 1 is a rectangular ring, and the top surface of the supporting frame 1 and the periphery of the diaphragm 2 can be fixed by glue so that the diaphragm 2 can vibrate up and down on the supporting frame 1. The speaker further comprises an annular seat 3 fixedly arranged on the bottom surface of the diaphragm 2 and a voice coil 5 placed inside the supporting frame 1. An embedding groove 6 is arranged on the bottom surface of the annular seat 3, and an annular insert 4 which can be embedded in the embedding groove 6 is fixedly arranged on the side of the voice coil 5 close to the diaphragm 2. However, in order to fix the diaphragm 2 and the voice coil 5, protrusions 7 are arranged on both sides of the annular insert 4. After the annular insert 4 is first embedded in the embedding groove 6, the protrusion 7 and the annular seat 3 are fixed by bolts 8, so that the annular insert 4 is fixed in the embedding groove 6 on the annular seat 3, and the assembly of the diaphragm 2 and the voice coil 5 is completed. When the voice coil 5 moves up and down, the diaphragm 2 vibrates, thereby making a sound. When the voice coil 5 needs to be replaced or repaired, the bolts 8 are loosened to make the annular insert 4 detach from the embedding groove 6, and the separation of the diaphragm 2 and the voice coil 5 is completed.

[0025] In addition, a magnetic circuit component 9 is provided inside the support frame 1, and part of the voice coil 5 is placed inside the magnetic circuit component 9. When the voice coil 5 is energized, the voice coil 5 will reciprocate under the action of the magnetic circuit component, so that the voice coil 5 and the diaphragm 7 vibrate; a clamping mechanism 10 for fixing the magnetic circuit component 9 in the support frame 1 is provided on the side of the support frame 1, and under the action of the clamping mechanism 10, the magnetic circuit component 9 and the support frame 1 are detachably connected. When the voice coil 5 needs to be replaced or repaired, the clamping mechanism 10 is controlled to unlock so that the magnetic circuit component 9 can be taken out of the support frame 1. After being taken out, the voice coil 5 can be replaced and repaired, and the magnetic circuit component 9 can also be repaired; after the repair is completed, the magnetic circuit component 9 is clamped with the support frame 1 by the clamping mechanism 10, so that the speaker is easy to install and saves costs during production.

[0026] like Figure 4 As shown, the magnetic circuit component 9 includes a U-shaped iron 901, a magnet 902 and a washer 903, wherein the U-shaped iron 901 includes a bottom plate and a pair of side plates clamped to the support frame 1 by a clamping mechanism 10, the side plates are symmetrically arranged on both sides of the bottom plate, and together with the bottom plate form a cavity with an opening facing upward, the magnet 902 is fixedly arranged on the bottom plate and placed in the middle of the cavity, the washer 903 is arranged on the top of the magnet 902, the U-shaped iron 901 and the washer 903 both play a role in magnetic conduction, and a magnetic gap is formed between the four sides of the washer 903 and the inner wall of the side plate, and the voice coil 5 and the diaphragm 2 are partially placed in the magnetic gap after assembly. The magnetic gap provides a uniform permanent magnetic field required for the movement of the voice coil 5. When current flows through the voice coil 5, an electromagnetic field is generated around the voice coil 5, and the positive pole of the voice coil 5 is attracted to the negative pole of the permanent magnetic field, and conversely, the negative pole repels from the negative pole of the permanent magnetic field. When the direction of the current in the voice coil 5 is changed to change its polarity, the magnetic force between the voice coil 5 and the permanent magnet also changes accordingly, and the direction of the current in the voice coil 5 is constantly changed, thereby pushing the voice coil 5 to move back and forth rapidly. When the voice coil 5 moves, it pushes and pulls the diaphragm 2 to perform reciprocating motion, causing the air in front of the speaker to vibrate and generate sound waves.

[0027] Furthermore, the clamping mechanism 10 includes a pair of fixed blocks 1002 respectively fixedly arranged on both sides of the length direction of the support frame 1, wherein a slide groove is provided on each fixed block 1002, and a guide rod 1003 whose axial direction is consistent with the length direction of the support frame 1 is fixedly provided in the slide groove, and a pair of sliders 1004 are slidably provided on the guide rod 1003, and the sliders 1004 are respectively placed at both ends of the slide groove; after force is applied to the sliders 1004 at both ends, the sliders 1004 can slide on the guide rod 1003 in the direction of approaching or moving away from each other. In addition, a pair of mirror-image slots 1007 are provided on the side panels on both sides of the U-shaped iron 901. The slots 1007 are L-shaped and are placed on the side of the side panel away from the magnet 902. A clamping rod 1006 is fixedly provided on each slider 1004, and one end of the clamping rod 1006 passes through the support frame 1 and extends into the clamping slot 1007 to clamp the U-shaped iron 901 in the support frame 1; when the driving slider 1004 slides on the guide rod 1003 in a direction approaching each other, the slider 1004 also moves in a direction approaching each other with the clamping rod 1006 on the same side, and the clamping rod 1006 slides in the clamping slot 1007. When the clamping rod 1006 slides to the specified position, the U-shaped iron 901 can be taken out of the support frame 1 from top to bottom, so that the clamping rod 1006 is separated from the clamping slot 1007, and the disassembly of the U-shaped iron 901 is completed. However, in order to facilitate the installation of the U-shaped iron 901, a limiting groove 1001 is provided on the inner side wall of the support frame 1 for limiting the side plate of the U-shaped iron 901. When the U-shaped iron 901 needs to be installed, the side plate of the U-shaped iron 901 is first embedded in the limiting groove 1001, and the clamping rod 1006 automatically slides into the clamping groove 1007, and then force is applied to the slider 1004 to make the slider 1004 slide in a direction away from each other, and the slider 1004 slides with the clamping rod 1006. After the slider 1004 slides to the two ends of the sliding groove on the fixed block 1002 respectively, the clamping rod 1006 clamps the U-shaped iron 901, and the assembly of the U-shaped iron 901 and the support frame 1 is completed. In addition, in order to enable the sliders 1004 to automatically slide in directions away from each other, a spring 1005 is provided on the guide rod 1003, and the spring 1005 is placed between the sliders 1004 on both sides. When the sliders 1004 slide in directions approaching each other, the spring 1005 will be compressed. After the force on the sliders 1004 stops, the sliders 1004 automatically reset to both sides under the action of the compressed spring 1005, and can also prevent the locking rod 1006 from detaching from the locking slot 1007, further improving the assembly effect.

[0028] In summary, it can be seen that the utility model has the above-mentioned excellent characteristics, which can enhance the performance unprecedented in the prior art and become a product with great practical value.

[0029] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation method and application scope. The content of this specification should not be understood as limiting the present invention.
