[0037] Due to the limitations of the ear size and the requirement for wearing comfort, the speaker units of existing headphones cannot be made large, which makes it difficult to improve the frequency loudness of the headphones. This has greatly limited the performance of headphones such as OWS headphones that have higher requirements for speaker performance.

[0038] Therefore, the technical solution proposes a speaker, comprising:

[0039] The basin frame 100 has a mounting cavity with one side open;

[0040] The magnetic circuit assembly 200 is disposed in the installation cavity and cooperates with the basin frame 100 to form a magnetic gap;

[0041] A vibration assembly 300 is disposed at the opening of the installation cavity, and the vibration assembly 300 has an extension portion 310, and the extension portion 310 extends into the magnetic gap; and

[0042] The magnetic conductive member 400 is disposed at the periphery of the opening of the installation cavity and extends close to the extension portion 310 .

[0043] In the technical solution of the utility model, the speaker includes a basin frame 100, the basin frame 100 has an installation cavity with an opening on one side, a magnetic circuit component 200 is arranged in the installation cavity, the magnetic circuit component 200 cooperates with the basin frame 100 to form a magnetic gap, and the magnetic circuit component 200 and the basin frame 100 together form a closed magnetic field loop; the speaker also includes a vibration component 300, the vibration component 300 is arranged at the opening of the installation cavity, the vibration component 300 has an extension portion 310, and the extension portion 310 extends into the magnetic gap; in addition, the speaker also includes a magnetic conductive member 400, the magnetic conductive member 400 is arranged at the periphery of the opening of the installation cavity and extends close to the extension portion 310, the magnetic conductive member 400 can correct the magnetic lines of force of the magnetic field, so that the magnetic field in the magnetic gap is more concentrated and uniform, thereby improving the driving effect of the vibration component 300, and then improving the frequency resonance of the speaker, so that speakers of the same size have better performance.

[0044] See also Figure 1 and Figure 2In one embodiment of the utility model, the speaker includes a basin frame 100, and the basin frame 100 is an overall cylindrical structure. The basin frame 100 is provided with an installation cavity with a top opening. The material of the basin frame 100 is a magnetic conductive material. A magnetic circuit component 200 is provided in the installation cavity. The magnetic circuit component 200 includes a magnet, and the magnet is arranged at the center of the installation cavity. In this way, the basin frame 100 and the magnet form a closed magnetic field. The magnetic lines of force of the magnetic field can go from the magnet to the bottom of the basin frame 100, then pass through the side wall of the basin frame 100, and finally return to the magnetic circuit component 200 from the edge of the basin frame 100 at the opening of the installation cavity. Depending on whether the magnet is in contact with the bottom wall of the installation cavity, the direction of the above magnetic lines of force is determined. The direction may be different; in addition, an annular magnetic gap is formed between the magnetic circuit component 200 and the basin frame 100, and the loudspeaker also includes a vibration component 300, which is arranged at the opening of the installation cavity, and the vibration component 300 has an extension portion 310, and the extension portion 310 extends into the magnetic gap. In this embodiment, the vibration component 300 includes a diaphragm and a voice coil arranged on the diaphragm, and the diaphragm is arranged at the opening of the installation cavity. The diaphragm is connected to a voice coil, and the voice coil is coaxially arranged with the diaphragm. One end of the voice coil extends into the magnetic gap to form the above-mentioned extension portion 310, and the extension portion 310 is located in the magnetic field. By passing an alternating current into the voice coil, the voice coil can drive the diaphragm to vibrate under the action of the magnetic field to produce sound. In addition, in order to improve the frequency response of the speaker, the speaker also includes a magnetic conductive part 400, which is arranged at the periphery of the opening of the installation cavity. The magnetic conductive part 400 may include a plurality of magnetic conductive plates arranged around the magnetic circuit assembly 200, and the plurality of magnetic conductive plates may be arranged at equal intervals. The magnetic conductive part 400 extends close to the extension portion 310. The magnetic conductive part 400 may be made of a material with good magnetic conductivity such as soft iron. By setting the magnetic conductive part 400, the magnetic lines of force in the magnetic gap may be corrected so that the magnetic lines of force are concentrated to the end of the magnetic conductive part 400 close to the magnetic circuit assembly 200, so that the extension portion 310 of the vibration assembly 300 can be driven by a stronger magnetic force, thereby improving the frequency response of the speaker, so that the speaker can improve performance without increasing its size, thereby meeting the requirements of headphones such as OWS.

[0045] Furthermore, the basin frame 100 is provided with an exhaust hole 110, and the exhaust hole 110 is connected to the magnetic gap. Figure 1 and Figure 2 In one embodiment, the basin frame 100 is further provided with an exhaust hole 110, which is connected to the magnetic gap. When the vibration component 300 vibrates, air can enter or be discharged from the space between the vibration component 300 and the basin frame 100 through the exhaust hole 110, thereby reducing the resistance of the vibration component 300 during vibration and improving the performance of the speaker. In addition, Figure 3In the conventional loudspeaker structure, the basin frame 100 and the vibration assembly 300 are fixed on the shell 500, and the shell 500 is provided with an air vent 600 to reduce the resistance of the vibration assembly 300 when vibrating. Compared with this structure, the present solution sets the exhaust hole 110 on the basin frame 100, so that when the overall size of the loudspeaker in the present solution is the same as that of the conventional loudspeaker, the size of the shell 500 bracket in the present solution can be further reduced and the size of the basin frame 100 and the magnetic circuit assembly 200 can be further increased, which is equivalent to improving the magnetic field strength of the magnetic circuit assembly 200, thereby improving the frequency response and other performances of the loudspeaker; and while increasing the size of the loudspeaker, the magnetic gap increases, and the setting of the magnetic conductive member 400 allows the magnetic lines of force to still be concentrated through the extension portion 310, that is, by using the combination of the two technical solutions of setting the magnetic conductive member 400 and the basin frame 100 to open the exhaust hole 110, while increasing the magnetic field strength, the magnetic lines of force passing through the extension portion 310 are also made more concentrated and uniform, thereby greatly improving the frequency response and other performances of the loudspeaker.

[0046] Furthermore, the exhaust hole 110 is provided on the bottom wall opposite to the opening in the installation cavity. Figure 1 In one embodiment, the exhaust hole 110 can be opened on the bottom wall of the installation cavity opposite to the opening. In this way, when the vibration component 300 vibrates, the air between the vibration component 300 and the basin frame 100 flows along the axis of the vibration component 300. The exhaust hole 110 is set on the bottom wall of the installation cavity so that the air can flow into or out of the magnetic gap smoothly from the exhaust hole 110, thereby further reducing the resistance to air flow and reducing the acoustic resistance of the speaker.

[0047] Furthermore, a plurality of exhaust holes 110 are provided, and the plurality of exhaust holes 110 are arranged at intervals around the magnetic circuit assembly 200. Figure 1 In one embodiment, a plurality of exhaust holes 110 may be provided, and the plurality of exhaust holes 110 may be arranged at equal intervals around the magnetic circuit assembly 200. This may make the air resistance of the vibration assembly 300 in the circumferential direction of the magnetic circuit assembly 200 more uniform, thereby ensuring the vibration stability of the vibration assembly 300 and alleviating polarization and other phenomena.

[0048] Furthermore, the exhaust hole 110 is an oblong hole. Figure 2 In one embodiment, the exhaust hole 110 may be an oblong hole extending along the circumference of the magnetic circuit assembly 200, so that the flow rate of a single exhaust hole 110 can be increased, which is beneficial to further reduce the acoustic resistance of the speaker.

[0049] Further, the magnetic conductive member 400 includes an annular magnetic conductive plate, which is arranged at the periphery of the opening of the installation cavity and surrounds the magnetic circuit assembly 200. In one embodiment, the magnetic conductive member 400 includes an annular magnetic conductive plate, which is arranged at the periphery of the opening of the installation cavity and extends around the magnetic circuit assembly 200. The arrangement of the annular magnetic conductive plate allows the magnetic field to act uniformly on the extension portion 310 in the circumferential direction around the magnetic circuit assembly 200, thereby allowing the vibration assembly 300 to receive a more stable driving force, thereby further improving the stability of the vibration assembly 300 during vibration.

[0050] Further, the magnetic circuit assembly 200 includes:

[0051] A central magnet 210 is disposed in the mounting cavity, and the central magnet 210 has a top surface facing away from the mounting cavity;

[0052] The central magnetic conductive plate 220 is disposed on the top surface of the central magnet 210 , and the central magnetic conductive plate 220 is flush with the annular magnetic conductive plate.

[0053] like Figure 1 In one embodiment, the magnetic circuit component 200 includes a central magnet 210 and a central magnetic conductive plate 220. The central magnet 210 is arranged in the installation cavity, and the central magnet 210 is coaxially arranged with the vibration component 300 and the basin frame 100. The central magnet 210 has a top surface facing away from the installation cavity, and the central magnetic conductive plate 220 is arranged on the top surface, and the central magnetic conductive plate 220 is arranged flush with the annular magnetic conductive plate. The magnetic lines of force can extend between the outer peripheral wall of the central magnetic conductive plate 220 and the side wall of the annular magnetic conductive plate. At this time, the magnetic lines of force are perpendicular to the extension part 310. When an alternating current is passed through the extension part 310, the extension part 310 can be subjected to the Ampere force along the axial direction of the extension part 310, so that the vibration component 300 can move along its axial direction, thereby preventing the occurrence of polarization.

[0054] Furthermore, the speaker further includes a housing 500, which is sleeved on the outside of the basin frame 100, and the vibration component 300 is connected to the housing 500. Figure 1 and Figure 2 In order to facilitate the fixation of the vibration component 300, the speaker also includes a shell 500, which can be a ring-shaped structure. The shell 500 is sleeved on the outside of the basin frame 100, and the outer periphery of the vibration component 300 can be bonded and fixed to the shell 500.

[0055] Furthermore, a fixing portion 510 is protruded from the inner wall of the housing 500 on the side facing the magnetic circuit assembly 200, and the fixing portion 510 cooperates with the basin frame 100 to clamp the magnetic conductive member 400. In order to improve the overall strength of the speaker, a fixing portion 510 is also protruded from the inner wall of the housing 500 on the side facing the magnetic circuit assembly 200, and the fixing portion 510 is annular in structure. During assembly, the fixing portion 510 cooperates with the periphery of the opening of the mounting cavity on the basin frame 100 to clamp and fix the magnetic conductive member 400. The setting of the fixing portion 510 facilitates the positioning and assembly between the magnetic conductive member 400, the housing 500 and the basin frame 100, and also ensures the stable position of the magnetic conductive member 400, thereby improving the reliability of the speaker.
