[0034] Here, the voice coil 21 is a closed coil, and the voice coil 21 can adopt a traditional voice coil structure, but the voice coil 21 does not need to be connected with the silk thread 40, and the positive and negative poles of the voice coil 21 are short-circuited, so that the silk thread 40 can be prevented from interfering with the vibration of the voice coil 21, the sound quality of the loudspeaker 100 is improved, and the sound of the loudspeaker 100 is more pure.

[0035] The conventional loudspeaker 100 can have a risk of breaking of the silk thread 40, but the voice coil 21 in the embodiment is not connected with the silk thread 40, and the silk thread 40 connected with the connection coil 31 is only connected with the audio signal and does not participate in vibration, so that the reliability of the entire loudspeaker is high, that is, the voice coil 21 is not limited by the silk thread 40, the failure risk of the loudspeaker 100 is reduced, and the reliability of the loudspeaker 100 is improved; meanwhile, the structure of the vibration assembly 20 can be more compact, and the size of the vibration assembly 20 is reduced.

[0037] According to the loudspeaker 100 of the utility model embodiment, the vibration of the voice coil 21 is not interfered with by the silk thread 40, the sound quality of the loudspeaker 100 is improved, the connection coil 31 is designed away from the voice coil 21, the size of the magnetic gap 301 is reduced, the performance of the voice coil 21 is ensured, and the sound quality of the loudspeaker 100 is improved.

[0038] Wherein, most of the structure of the vibration assembly 20 can be installed on the inner side of the yoke 10, a part of the voice coil 21 is arranged in the yoke 10, and a part can extend out of the yoke 10, and the magnetic circuit system 30 is arranged on the outer side of the yoke 10. The yoke 10 can be mounted on the vehicle body of the vehicle 200, and the magnetic circuit system 30 and the vibration assembly 20 are installed by means of the yoke 10, which is convenient for installation, and can reduce the interference between the magnetic circuit system 30 and the vibration assembly 20.

[0039] The lead coil 31 can connect the audio signal through the silk thread 40, and the silk thread 40 can be directly connected to the power amplifier. The signal released by the power amplifier is transmitted to the bottom lead coil 31. The audio signal transmitted by the power amplifier is an alternating current signal, and an alternating voltage is generated in the lead coil 31, thereby generating a changing magnetic field.

[0040] As shown in Figure 2 some embodiments, the magnetic assembly includes a magnetic conducting column 34, a magnet 32 and a magnetic conducting plate 33, the magnetic conducting plate 33 is connected with the yoke 10, the magnet 32 and the magnetic conducting plate 33 are sleeved on the magnetic conducting column 34 respectively, and a magnetic gap 301 is formed between the magnetic conducting plate 33 and the magnetic conducting column 34. Thus, the magnetic assembly is installed on the outer side of the yoke 10 through the magnetic conducting plate 33, and the magnetic assembly can form its own static magnetic field. The magnetic conducting plate 33 is a pot core, and the magnetic conducting plate 33 can be connected with the yoke 10 by fasteners or adhesion.

[0041] As shown in Figure 2 and Figure 3 some embodiments, the magnetic conducting column 34 includes a column body 341 and a plate body 342, the plate body 342 is arranged at one end of the column body 341, the magnetic conducting plate 33 is sleeved on the outer side of the column body 341, the magnetic gap 301 is formed between the magnetic conducting plate 33 and the column body 341, and the magnet 32 is sleeved on the outer side of the column body 341 and located between the plate body 342 and the magnetic conducting plate 33. Thus, the magnet 32 can be adhesively matched with the magnetic conducting column 34 and the magnetic conducting plate 31 respectively, the overall structure is simple, the layout is compact and reasonable, and the magnetic conducting column 34 can be a T-shaped iron.

[0042] As shown in Figure 2 some embodiments, the lead coil 31 is arranged on the side of the plate body 342 away from the column body 341. Thus, the lead coil 31 and the voice coil 21 are respectively located on the two sides of the plate body 342, which is convenient for installation of the lead coil 31 and can reduce the interference between the lead coil 31 and the voice coil 21 and reduce abnormal sound.

[0043] As shown in Figure 2As shown, in some embodiments, the magnetic circuit system 30 further includes a magnetic conductor 35, which is disposed on the side of the plate 342 away from the column 341.

[0044] In some other embodiments, the wiring coil 31 is located on the outer periphery of the plate 342. The wiring coil 31 can be directly wound around the outer periphery of the plate 342, which can eliminate the need for components such as the magnetic conductor 35, further reducing the number of parts. This is beneficial for simplifying the size of the magnetic circuit system 30, reducing the overall size of the speaker 100 in the vibration direction of the voice coil 31, and promoting the miniaturization of the speaker 100.

[0051] In addition, the dust cap 11 is further arranged on the yoke 10, the dust cap 11 is located at the center position of the diaphragm 22 of the loudspeaker 100 and covers the voice coil 21, the dust cap 11 can prevent dust from entering and plays a role of protecting the voice coil 21.

[0052] As Figure 4 According to the utility model, a vehicle 200 is further provided, which comprises the loudspeaker 100 according to the utility model, by adopting the loudspeaker 100, the vibration of the voice coil 21 is not interfered by the silk thread 40, and the lead coil 31 is designed to be far away from the voice coil 21, which is beneficial to reducing the size of the magnetic gap 301, thereby ensuring the performance of the voice coil 21 and improving the sound quality of the loudspeaker 100, and the loudspeaker 100 is compact in structure and can be installed in various environments of the vehicle 200, thereby improving the use experience and market competitiveness of the vehicle 200.
