[0029] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0030] Please refer to Figures 1 to 6 A new type of speaker includes a basin frame 1 and a vibration component and a magnetic circuit component arranged on the basin frame 1, the vibration component includes a diaphragm 2 and a voice coil 3, the diaphragm 2 is connected to one end of the basin frame 1, the voice coil 3 is connected to the inner side of the diaphragm 2, the magnetic circuit component is installed at the end of the basin frame 1 away from the diaphragm 2, the magnetic circuit component has a magnetic gap corresponding to the voice coil 3, and the magnetic circuit component can move relative to the basin frame 1 to approach or move away from the vibration component.

[0031] From the above description, it can be seen that the beneficial effect of the utility model is that the magnetic circuit component of the new speaker is movably mounted on the basin frame 1, so that the distance between the magnetic circuit component and the vibration component can be adjusted, so that the user can adjust the sensitivity of the new speaker according to actual use needs, and then adjust the high-frequency performance and low-frequency performance of the new speaker.

[0032] Furthermore, the magnetic circuit assembly includes a yoke 4 and a magnetic steel 5 . The yoke 4 can be movably mounted on an end of the basin frame 1 away from the diaphragm 2 , and the magnetic steel 5 is connected to the inner side of the yoke 4 .

[0033] It can be seen from the above description that the yoke 4 is used to guide the magnetic flux lines of the magnetic steel 5 , which is beneficial to increase the B value and improve the use efficiency of the magnetic steel 5 .

[0034] Furthermore, the yoke 4 includes a bottom plate 41 and a peripheral wall 42 formed by bending and extending the bottom plate 41 toward a side close to the vibration component, the magnetic steel 5 is connected to the inner side surface of the bottom plate 41, and the voice coil 3 is arranged between the peripheral wall 42 and the magnetic steel 5.

[0035] From the above description, it can be seen that the bottom plate 41 and the peripheral wall 42 of the yoke 4 can guide more magnetic flux lines of the magnet 5 to the position of the voice coil 3, thereby improving the B value and maximizing the use efficiency of the magnet 5.

[0036] Furthermore, the magnetic circuit assembly also includes a washer 6 , and the washer 6 is connected to a side of the magnetic steel 5 away from the yoke 4 .

[0037] From the above description, it can be seen that the washer 6 is used to further guide the magnetic flux lines, which is beneficial to improving the sensitivity of the new speaker and reducing distortion.

[0038] Furthermore, the magnetic circuit assembly is threadedly connected to the basin frame 1.

[0039] From the above description, it can be seen that the connection method between the magnetic circuit assembly and the basin frame 1 is simple. The relative position of the magnetic circuit assembly and the vibration assembly can be changed by only rotating the magnetic circuit assembly and the basin frame 1 relative to each other.

[0040] Furthermore, the basin frame 1 is provided with a first internal thread portion 11 , and the yoke 4 is provided with an external thread portion 43 that matches the first internal thread portion 11 .

[0041] As can be seen from the above description, the yoke 4 is arranged inside the basin frame 1, which can avoid guiding the magnetic flux lines to the outside of the basin frame 1, and the magnetic circuit component is easy to disassemble and assemble for repeated use or replacement of different models.

[0042] Furthermore, a first limiting boss 44 is provided on the outer peripheral surface of one end of the yoke 4 away from the vibration assembly.

[0043] It can be seen from the above description that the first limiting boss 44 is used to limit the closest relative position of the magnetic circuit component and the vibration component to avoid contact between the magnetic circuit component and the vibration component.

[0044] Furthermore, a second limiting boss 45 is provided on the outer peripheral surface of one end of the yoke 4 close to the vibration assembly.

[0045] It can be known from the above description that the second limiting boss 45 is used to abut against the basin frame 1 so as to prevent the magnetic circuit assembly from being separated from the basin frame 1 .

[0046] Furthermore, it also includes a limiting ring 7 , on which a second internal thread portion 71 matching with the external thread portion 43 is provided.

[0047] As can be seen from the above description, the limiting ring 7 is used to limit the relative position of the basin frame 1 and the magnetic circuit assembly to prevent the basin frame 1 and the magnetic circuit assembly from moving relative to each other, thereby determining the sensitivity of the novel speaker.

[0048] Furthermore, the basin frame 1 includes a basin frame body 12 and a connecting ring 13 disposed on the basin frame body 12 , and the connecting ring 13 is provided with the first internal threaded portion 11 .

[0049] As can be seen from the above description, the connection ring 13 and the basin frame body 12 are designed to be separated, which is conducive to reducing the difficulty of producing the basin frame body 12 and allowing the connection ring 13 and the basin frame body 12 to be made of different materials according to usage requirements.

[0050] Please refer to Figure 1 and Figure 2Embodiment 1 of the utility model is: a novel speaker, comprising a basin frame 1 and a vibration assembly and a magnetic circuit assembly arranged on the basin frame 1, the vibration assembly comprising a diaphragm 2 and a voice coil 3, the diaphragm 2 is connected to one end of the basin frame 1, the voice coil 3 is connected to the inner side of the diaphragm 2, the magnetic circuit assembly is installed at the end of the basin frame 1 away from the diaphragm 2, the magnetic circuit assembly has a magnetic gap corresponding to the voice coil 3, and the magnetic circuit assembly can move relative to the basin frame 1 to approach or move away from the vibration assembly.

[0051] Specifically, the magnetic circuit assembly includes a yoke 4 and a magnet 5. The yoke 4 is movably mounted on one end of the basin frame 1 away from the diaphragm 2, and the magnet 5 is connected to the inner side of the yoke 4. The yoke 4 includes a bottom plate 41 and a peripheral wall 42 formed by bending and extending the bottom plate 41 toward a side close to the vibration assembly. The magnet 5 is connected to the inner side of the bottom plate 41. The magnetic gap is formed between the peripheral wall 42 and the magnet 5. The voice coil 3 is arranged between the peripheral wall 42 and the magnet 5, and the voice coil 3 is arranged without contact with the yoke 4. The voice coil 3 is arranged without contact with the magnet 5. The diaphragm 2 is circular, the voice coil 3 is cylindrical, the bottom plate 41 of the yoke 4 is circular, the peripheral wall 42 of the yoke 4 is cylindrical, and the magnet 5 is cylindrical. The central axes of the diaphragm 2, the voice coil 3, the yoke 4 and the magnet 5 are arranged in a colinear manner. A first internal thread portion 11 is provided on the inner circumference of the basin frame 1, and an external thread portion 43 matching the first internal thread portion 11 is provided on the outer circumference of the peripheral wall 42 of the yoke 4. It is easy to understand that the relative position of the magnet 5 and the voice coil 3 can be changed by rotating the yoke 4, so as to adjust the sensitivity of the new speaker. When the magnetic circuit assembly moves toward the direction close to the vibration assembly, so that the length of the voice coil 3 extending into the gap between the magnet 5 and the peripheral wall 42 increases, the magnetic flux lines passing through the voice coil 3 decrease, the sensitivity of the new speaker decreases, and the low-frequency performance improves; when the magnetic circuit assembly moves toward the direction away from the vibration assembly, so that the length of the voice coil 3 extending into the gap between the magnet 5 and the peripheral wall 42 decreases, the magnetic flux lines passing through the voice coil 3 increase, the sensitivity of the new speaker increases, and the high-frequency performance improves. In addition, the magnetic circuit assembly is easy to disassemble and assemble for repeated use or replacement of different models.

[0052] The magnetic circuit assembly also includes a washer 6, which is connected to a side of the magnetic steel 5 away from the yoke 4. Specifically, the washer 6 is cylindrical, and the washer 6 is arranged colinearly with the central axis of the magnetic steel 5. The washer 6 is used to further guide the magnetic flux lines, which is beneficial to improve the sensitivity of the novel speaker and reduce distortion.

[0053] A first limiting boss 44 is provided on the outer peripheral surface of one end of the yoke 4 away from the vibration assembly. Specifically, the first limiting boss 44 is exposed on the basin frame 1. The first limiting boss 44 is in the shape of a circular ring, and the first limiting boss 44 and the yoke 4 are an integral structure formed in one piece. The outer diameter of the first limiting boss 44 is larger than the inner diameter of the hole-like structure on the basin frame 1 on which the first internal threaded portion 11 is provided. The first limiting boss 44 is used to limit the closest relative position between the magnetic circuit assembly and the vibration assembly to avoid contact between the magnetic circuit assembly and the vibration assembly. In other embodiments, the number of the first limiting bosses 44 is multiple, and it is also feasible to arrange multiple first limiting bosses 44 around the periphery of the yoke 4.

Specifically, the limit ring 7 is arranged outside the basin frame 1, and the limit ring 7 is located between the basin frame 1 and the first limit boss 44. The limit ring 7 is used to limit the relative position of the basin frame 1 and the magnetic circuit assembly to prevent the basin frame 1 and the magnetic circuit assembly from moving relative to each other, thereby determining the sensitivity of the speaker of the present invention.

[0055] Please refer to Figure 5 and Figure 6 The third embodiment of the present invention is a further improvement of the basin frame 1 and the yoke 4 based on the first embodiment, and the difference from the first embodiment is that:

[0057] A second limiting boss 45 is provided on the outer peripheral surface of one end of the yoke 4 close to the vibration assembly. Specifically, the second limiting boss 45 is arranged in the basin frame 1. The second limiting boss 45 is in the shape of a circular ring, and the second limiting boss 45 and the yoke 4 are an integral structure formed integrally. The outer diameter of the second limiting boss 45 is larger than the inner diameter of the hole-shaped structure of the basin frame 1 for mounting the magnetic circuit assembly. The second limiting boss 45 is used to abut against the basin frame 1 to prevent the magnetic circuit assembly from detaching from the basin frame 1. In other embodiments, the number of the second limiting bosses 45 is multiple, and it is also feasible to arrange multiple second limiting bosses 45 around the periphery of the yoke 4.
