[0035] Basin rack 1, the number of the basin rack 1 is two, and the two basin racks 1 are connected;

[0036] A yoke 2 is installed between the two basin frames 1, and the yoke 2 includes a main magnetic plate 21 and two side magnetic plates 22 respectively connected to both sides of the main magnetic plate 21;

[0037] Magnetic steel 3, the magnetic steel 3 is respectively provided on the top surface and the bottom surface of the main magnetic plate 21;

[0038] A vibration component 4, each of the two basin frames 1 is provided with a vibration component 4;

[0039] The vibration motor 5 includes a vibration plate 51, a coil 52 and a magnetic circuit unit 53. The coil 52 is connected to the outer side surface of the side magnetic conductive plate 22. The vibration plate 51 is arranged on the side of the coil 52 away from the side magnetic conductive plate 22. The vibration plate 51 is flexibly connected to the basin frame 1. The magnetic circuit unit 53 is connected to the side of the vibration plate 51 close to the side magnetic conductive plate 22.

[0040] As can be seen from the above description, the beneficial effects of the present invention are as follows: the interaction between the two sets of vibration components 4 and the magnet 3 of the multifunctional speaker enables double-sided sound generation, and the coil 52 drives the magnetic circuit unit 53 and the vibration plate 51 to vibrate, thereby realizing the vibration reminder function. The yoke 2 not only serves as a magnetic conductor in the speaker portion, but also supports and serves as a magnetic conductor for the vibration motor 5, thereby reducing the number of parts in the multifunctional speaker, improving space utilization, and reducing the occupied space.

[0041] Furthermore, the cross section of the yoke 2 is H-shaped.

[0042] From the above description, it can be seen that the H-shaped structure is symmetrical up and down, which is beneficial to making the sound of the multifunctional speaker balanced up and down, and the left-right symmetrical structure is beneficial to the vibration balance on both sides of the vibration component 4, thereby reducing distortion.

[0043] Furthermore, a first washer 31 is included. The first washer 31 is connected to a side of the magnetic steel 3 away from the main magnetic plate 21 .

[0044] It can be seen from the above description that the provision of the first washer 31 can further play a role in magnetic conduction, thereby improving the sensitivity of the multifunctional loudspeaker and reducing distortion.

[0045] Furthermore, a receiving groove 11 is provided on the side wall of the basin frame 1 , and the vibration motor 5 is disposed in the receiving groove 11 .

[0046] It can be seen from the above description that placing the vibration motor 5 in the receiving groove 11 of the basin frame 1 can further improve the space utilization of the multifunctional speaker.

[0047] Furthermore, the vibration motor 5 further includes an elastic member 54 , and the vibration plate 51 is connected to the basin frame 1 via the elastic member 54 .

[0049] Furthermore, the basin frame 1 and the vibration plate 51 are respectively provided with limiting pits 121 , and both ends of the elastic member 54 are respectively provided in the limiting pits 121 .

[0050] From the above description, it can be seen that the limiting pit 121 can limit the position of the elastic member 54, facilitate assembly, and prevent the elastic member 54 from being over-pressurized and causing failure. When the two ends of the elastic member 54 are respectively glued to the basin frame 1 and the vibration plate 51, the limiting pit 121 can also accommodate glue, thereby making the connection between the elastic member 54 and the basin frame 1 and the vibration plate 51 more secure.

[0051] Furthermore, a connecting block 12 is provided on the basin frame 1 , and the limiting pit 121 is provided on the connecting block 12 .

[0052] It can be seen from the above description that providing the limiting pit 121 on the connecting block 12 can reduce the manufacturing difficulty of the basin frame 1 and improve the production efficiency.

[0053] Furthermore, the elastic member 54 is a spring, a spring sheet or a spring washer.

[0054] As can be seen from the above description, the type of the elastic member 54 can be selected according to actual use requirements or production conditions.

[0055] Furthermore, the vibration motor 5 further includes a second washer 55 , and the second washer 55 is connected to a side of the magnetic circuit unit 53 away from the vibration plate 51 .

[0056] As can be seen from the above description, the second washer 55 can play a role in magnetic conduction, thereby improving the sensitivity of the vibration motor 5 and reducing energy consumption.

[0057] Furthermore, it also includes a high-pitched sound unit 6, which is arranged on the side wall of the basin frame 1.

[0058] It can be seen from the above description that providing the tweeter sound unit 6 can increase the effective bandwidth of the multifunctional speaker and meet more demands of consumers.

[0059] Please refer to Figures 1 to 6 The first embodiment of the present invention is a multifunctional speaker comprising a frame 1, a yoke 2, a magnet 3, a vibration assembly 4, and a vibration motor 5. Two frames 1 are connected vertically. The yoke 2 is mounted between the two frames 1, and has an H-shaped cross-section. The yoke 2 comprises a main magnetic plate 21 and two side magnetic plates 22 connected to either side of the main magnetic plate 21. The main magnetic plate 21 is provided with magnets 3 on its top and bottom surfaces, respectively. A vibration assembly 4 is provided on each of the two frames 1. The vibration motor 5 comprises a vibration plate 51, a coil 52, and a magnetic circuit unit 53. The coil 52 is connected to the outer side of the side magnetic plates 22. The vibration plate 51 is provided on the side of the coil 52 away from the side magnetic plates 22. The vibration plate 51 is flexibly connected to the frame 1, and the magnetic circuit unit 53 is connected to the side of the vibration plate 51 near the side magnetic plates 22. In this embodiment, the magnetic circuit unit 53 is a magnet. The coil 54 is connected to the side magnetic plates 22 using hot melt adhesive, silicone, or double-sided tape. The vibration assembly 4 includes a diaphragm connected to the basin frame 1 and a voice coil connected to the inner side of the diaphragm. The diaphragm includes a diaphragm body and a middle sticker. The diaphragm body includes an outer fixing part, a folding ring part and an inner fixing part connected in sequence from the outside to the inside. The middle sticker is connected to the outer side of the inner fixing part.

[0060] like Figure 4As shown, in order to improve sensitivity and reduce distortion, the multifunctional speaker further includes a first washer 31, which is connected to the side of the magnet 3 away from the main magnetic plate 21. The number of the first washers 31 corresponds to the number of the magnets 3.

[0061] like Figure 1 and Figure 4 As shown, a receiving groove 11 is provided on the side wall of the basin frame 1, and the vibration motor 5 is provided in the receiving groove 11. Specifically, the receiving groove 11 communicates with the inner side and the outer side of the side wall of the basin frame 1, and the vibration motor 5 is completely accommodated in the receiving groove 11.

[0062] like Figure 5 and Figure 6 As shown, the vibration motor 5 also includes an elastic member 54, connecting the vibration plate 51 to the basin frame 1 via the elastic member 54. Specifically, the vibration plate 51 is rectangular, with three elastic members 54 positioned at each end. The elastic members 54 are springs. The ends of the elastic members 54 are adhesively connected to the vibration plate 51 and the basin frame 1, respectively. In other embodiments, it is also feasible to have one, two, or more elastic members 54 at each end of the vibration plate 51; the elastic members 54 can be configured as spring clips or spring washers.

[0063] like Figure 5 and Figure 6 As shown, the basin frame 1 and the vibration plate 51 are respectively provided with limiting recesses 121, and the ends of the elastic member 54 are respectively disposed in the limiting recesses 121. The limiting recesses 121 can limit the position of the elastic member 54, facilitating assembly and preventing the elastic member 54 from being over-stressed and causing failure. The limiting recesses 121 can also accommodate glue, thereby further strengthening the connection between the elastic member 54, the basin frame 1 and the vibration plate 51.

[0064] like Figure 5 and Figure 6 As shown, in order to reduce the manufacturing difficulty of the basin frame 1, the basin frame 1 is provided with a connecting block 12, and the connecting block 12 is provided with a limiting pit 121. Specifically, the connecting block 12 is fixedly connected to the side wall of the basin frame 1 by glue.

[0065] like Figure 4 and Figure 6 As shown, in order to improve the sensitivity of the vibration motor 5 and reduce energy consumption, the vibration motor 5 further includes a second washer 55 , which is connected to a side of the magnetic circuit unit 53 away from the vibration plate 51 .

[0066] like Figure 2 、 Figure 4 and Figure 6As shown, the multifunctional speaker also includes a tweeter unit 6, which is mounted on the side wall of the frame 1. Specifically, the magnetic circuit assembly of the tweeter unit 6 is connected to the outer surface of a magnetic conductive plate 22 on the side of the yoke 2 away from the vibration motor 5. The sound-emitting portion of the tweeter unit 6 faces away from the yoke 2. The tweeter unit 6 is completely housed in the receiving groove 11 of the frame 1.

[0067] During operation of the multifunctional speaker, the two vibration components can realize double-sided sound generation, and the two vibration components completely cancel out the vibration in the vertical direction. The vibration generated by the tweeter sound unit 6 during operation is relatively small, so the vibration motor 5 can become the only controllable vibration source.

[0068] In summary, the multifunctional speaker provided by this invention achieves dual-sided sound generation through the interaction of its two vibration components and the magnets. The coil drives the magnetic circuit unit and the vibration plate to vibrate, thereby realizing a vibration reminder function. The yoke not only acts as a magnetic conductor for the speaker, but also supports and guides the vibration motor, thus reducing the number of parts in the multifunctional speaker, improving space utilization, and reducing the space occupied.
