[0002] Audio cables are cables that connect audio equipment and are used to transmit audio signals, passing the signals from the music source to the amplifier, which is then converted into sound by the speaker. It involves multiple fields such as electroacoustic engineering, signal processing, electromagnetic compatibility, and material science. There are different types of audio cables, such as RCA cables, XLR cables, TRS cables, etc. Depending on their use and performance requirements, they have a shielding layer to reduce electromagnetic interference and use high-quality conductor materials to ensure the purity of the sound.

DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0024] Example 1: Speaker cable with good shielding and insulation, see Figure 1-Figure 4 As shown, it includes a connecting line 1, a joint 2, and a guide frame 201. Joints 2 are provided at both ends of the connecting line 1. A guide frame 201 is installed between the joint 2 and the connecting line 1. It also includes a limiting frame 3, an insulating sleeve 4, a first guide rod 5, a first elastic member 6 and a sealing gasket 7. The limiting frame 3 is fixedly connected to the guide frame 201, and an insulating sleeve 4 is sleeved on the joint 2. The insulating sleeve 4 is made of rubber and has good flexibility. Four first guide rods 5 are installed on the side of the insulating sleeve 4 close to the limiting frame 3. The first guide rods 5 slide on the limiting frame 3. Sealing gaskets 7 are embedded on both sides of the insulating sleeve 4. The sealing gasket 7 is in sliding contact with the joint 2. Four first elastic members 6 are connected between the limiting frame 3 and the insulating sleeve 4. The first elastic member 6 is sleeved on the first guide rod 5. A protective cover 19 is provided on the outside of the first elastic member 6. The protective cover 19 is used to protect the first elastic member 6 to prevent the first elastic member 6 from dust accumulation and rust corrosion.

[0025] When using the audio connection line 1, first slide the insulating sleeve 4 inwards. The insulating sleeve 4 is subjected to force to drive the first guide rod 5 to slide along the limit frame 3. The insulating sleeve 4 squeezes the first elastic member 6 and is deformed. Then, connect the connector 2 to the interface of the audio system. Then release the insulating sleeve 4. The first elastic member 6 returns to its original state and drives the insulating sleeve 4 to slide outwards, so that the insulating sleeve 4 covers the connector 2 and the audio interface. At this time, the two sealing gaskets 7 are respectively sealed with the connector 2 and the audio interface, thereby sealing and insulating the connector 2 and the audio interface to prevent leakage when the connecting line 1 and the audio system are connected. At the same time, the connecting line 1 and the audio interface are shielded to prevent noise or sound distortion when the audio system is used.

[0026] Example 2: Based on Example 1, refer to Figure 4 and Figure 5 As shown, it also includes a first connecting plate 8, a guide plate 9, a second guide rod 10, an anti-slip plate 11 and a second elastic member 12. Four first connecting plates 8 are installed on the guide frame 201. The guide plate 9 is installed on the side of the first connecting plate 8 away from the center of the joint 2. Four second guide rods 10 are fixedly connected in the guide frame 201. The anti-slip plate 11 is slidably arranged on the second guide rod 10. The anti-slip plate 11 is slidably connected to the adjacent guide plate 9. The second elastic member 12 is connected between the guide frame 201 and the anti-slip plate 11.

[0027] When the user connects the connecting line 1 to the audio system, the anti-dropping plate 11 is first slid outward along the second guide rod 10, and the anti-dropping plate 11 squeezes the second elastic member 12 to deform, and then the four anti-dropping plates 11 are separated, and then the connecting line 1 is connected to the audio interface, and then the anti-dropping plate 11 is loosened, and the second elastic member 12 returns to its original state and drives the anti-dropping plate 11 to slide inward and engage with the audio interface, thereby fixing the connecting line 1 to the audio interface to prevent the connecting line 1 from falling off when connected to the audio system.

[0028] See also Figure 5 and Figure 6 As shown, it also includes a third guide rod 13, a connecting frame 14, a push plate 15 and a third elastic member 16. Four third guide rods 13 are fixedly connected to one side of the guide frame 201 close to the connecting line 1. The connecting frame 14 is slidably arranged on the four third guide rods 13. Four third elastic members 16 are connected between the connecting frame 14 and the guide frame 201. Four push plates 15 are fixedly connected to the connecting frame 14. The push plates 15 are in sliding contact with adjacent anti-drop plates 11. One end of the latch 20 passes through the connecting frame 14 and slides in the third guide rod 13. The latch 20 limits the connecting frame 14 to prevent the anti-drop plate 11 from being loosened when the connecting frame 14 is accidentally touched.

[0029] When it is necessary to connect or disconnect the connecting cable 1 to the audio interface, the user pushes the connecting frame 14 to slide along the third guide rod 13, and the push plate 15 squeezes the anti-drop plate 11 to slide outward and open, and then connects or disconnects the connecting cable 1 to the audio interface, thereby eliminating the need to slide the anti-drop plate 11 outward one by one, thereby improving the efficiency of connecting or disconnecting the connecting cable 1 to the audio interface.

[0030] See also Figure 1 and Figure 7 As shown, it also includes a circuit clamping plate 17 and a second connecting plate 18. The circuit clamping plates 17 are fixedly connected to both sides of the second connecting plate 18. The two circuit clamping plates 17 are respectively clamped to the two ends of the connecting line 1.

[0031] When the connecting wire 1 needs to be bent and fixed, the two circuit clamping plates 17 are clamped with the connecting wire 1 so that the two circuit clamping plates 17 are sleeved on both ends of the connecting wire 1, thereby bending and fixing the connecting wire 1 to prevent the connecting wire 1 from being too long and scattered during use.
