[0002] The speaker is a very commonly used electroacoustic transducer device that can be found in all electronic and electrical devices that produce sound. The speaker is a transducer device 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 the speaker is in use, the surface area of the cone is large and relatively fragile. During use, dust and debris are prone to accumulation. At the same time, if it comes into contact with foreign objects, the cone is prone to deformation or damage.
[0004] Therefore, a speaker with an edge-wrapped protection structure is needed to solve the above problems. Utility Model Content

The top end of the collar 10 is fixed with a positioning ring 12, the center position of the top end of the collar 10 is fixed with an inner lining ring 13, and the inner side of the inner lining ring 13 is installed with an isolation net 14;
[0025] Specifically, if Figure 1 、 Figure 2 and Figure 3 As shown, when in use, the collar 10 is wrapped around the outside of the top frame 7. At the same time, under the adsorption between the magnetic block 11 and the iron ring 9, it is adsorbed and fixed on the outside of the top frame 7 for use. The inner lining ring 13 at the top center is used to transmit sound to the outside. The isolation net 14 inside the inner lining ring 13 is used to isolate external objects to prevent foreign objects from contacting the sound cone 8 on the inside of the top frame 7. Because the collar 10 and the top frame 7 are fixed by magnetic adsorption, the collar 10 can be removed by applying external force upwards at a later stage to facilitate maintenance and other operations.
[0026] A wire platform 15 is fixed to the left side of the basin frame 5. A wire hole 16 is provided on the left side of the wire platform 15. A connecting wire 17 is provided inside the wire hole 16. The right side of the connecting wire 17 is fixedly connected to the left side of the voice coil 4.

[0027] Specifically, if Figure 1 、 Figure 2 and Figure 4 As shown, when in use, the connecting wire 17 at the side end of the voice coil 4 is passed through the wire hole 16 inside the wire platform 15 to the outside, and then the fixing bolt 20 below can be rotated. When the fixing bolt 20 and the friction plate 22 move upward, the connecting wire 17 can be pressed against the wire hole 16 to fix it, thereby preventing external tension from causing the connecting wire 17 to separate from the voice coil 4;
[0028] A heat conducting ring 23 is fixed to the outer wall of the magnetic column 1, and a heat conducting rod 24 is fixed inside the heat conducting ring 23.

After the connecting wire 17 is connected, the knob 21 below can be rotated to rotate the fixing bolt 20 and the friction plate 22 upward. The fixing bolt 20 cooperates with the friction plate 22 to assist in fixing the connecting wire 17 against the inside of the wire hole 16 to prevent the outer connecting wire 17 from being pulled and causing the connection between the inner connecting wire 17 and the voice coil 4 to break. After that, the ring 10 can be put on the top frame. 7 is used, the magnetic block 11 on the inside of the ring 10 is adsorbed with the iron ring 9 on the outside of the top frame 7, and the ring 10 can be fixed. When the ring 10 is put on the outside of the top frame 7, it cooperates with the isolation net 14 to shield and protect the sound basin 8 on the inside of the top frame 7 to prevent foreign objects from contacting the sound basin 8. During use, when the heat of the magnetic column 1 is transferred to the outside, the heat-conducting ring 23 and the heat-conducting rod 24 can assist in transferring the heat to the multiple groups of heat sinks 25 on the outside. The multiple groups of heat sinks 25 have a larger contact area with the air and can perform heat dissipation more quickly.
