[0028] To make the objectives, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] An embodiment of the present utility model provides a speaker structure, including a speaker assembly and a first magnetic adsorption type terminal assembly. The speaker assembly is a modular standard component, and a first magnetic adsorption type terminal assembly is arranged at one end thereof. The first magnetic adsorption type terminal assembly is used to connect with a main board, thereby realizing the installation of the speaker structure.

[0030] The following will describe in detail the speaker structure, the main board, and each component of the electronic product, as well as the connection relationship and position relationship among the components, provided by the embodiments of the present utility model with reference to the accompanying drawings.

[0031] As Figure 1 and Figure 2 shown, in the embodiment of the present utility model, the speaker assembly 10 includes a horn cavity 11 and a horn unit 12. The horn cavity 11 includes a window, and the horn unit 12 is located inside the horn cavity 11, and the diaphragm of the horn unit 12 is located at the window position; for example, the horn cavity 11 is columnar, shown as a cuboid in the figure, or cylindrical, etc., and the outer shape of the horn cavity 11 is a regular shape. The speaker assembly 10 is a modular structure, and on the premise of ensuring the speaker performance, it also has the advantages of small occupied space, diversified position setting / combination, and meeting personalized settings.

[0032] The speaker assembly 10 is connected to the main board through the first magnetic adsorption terminal assembly 20. Among them, a corresponding docking structure is provided at one end of the main board, and the docking structure is described in the following text. The first magnetic adsorption terminal assembly 20 is arranged on the outer wall of the speaker cavity 11. For example, one end of the speaker cavity 11 includes a cavity cover 13, and the first magnetic adsorption terminal assembly 20 is arranged on the cavity cover 13; the first magnetic adsorption terminal assembly 20 includes a first positive terminal 21, a first negative terminal 22 and a first magnet 23. The first positive terminal 21 and the first negative terminal 22 are respectively connected to the positive and negative poles of the speaker unit 12 through wire harnesses, and the wire harnesses are located inside the speaker cavity 11.

[0033] When the first magnetic adsorption terminal assembly 20 is connected, it is magnetically adsorbed to the connection position through the first magnet 23. Then, the first positive terminal 21 and the first negative terminal 22 are connected to the pole pieces at the connection position, thereby realizing the installation of the speaker structure.

[0034] For example, the first positive terminal 21 and the first negative terminal 22 are annular, the diameter of the first negative terminal 22 is larger than that of the first positive terminal 21, and the centers of the first positive terminal 21 and the first negative terminal 22 coincide. Or, for example, the first magnet 23 is located at the center of the first positive terminal 21 and the first negative terminal 22, and the center of the first magnet 23 coincides with the centers of the first positive terminal 21 and the first negative terminal 22.

[0035] The relative positions of the first positive terminal 21, the first negative terminal 22 and the first magnet 23 are fixed. When the first magnet 23 is connected to the adsorbed structure, the positions of the first positive terminal 21 and the first negative terminal 22 are fixed. Therefore, by arranging a pole piece structure around the structure adsorbed by the first magnet 23, the alignment connection of the first positive terminal 21 and the first negative terminal 22 can be ensured.

[0036] For example, the structure adsorbed by the first magnet 23 is also a magnet structure. The connection between the magnets can further ensure that the position of the first magnet 23 is a fixed position, and then ensure the stable connection between the pole pieces; and the first positive terminal 21 and the first negative terminal 22 adopt an annular structure, which can also ensure the full connection between the pole pieces, achieving the purpose of stable connection, and when the angle of the speaker assembly 10 is changed, the speaker assembly 10 can still maintain an effective connection.

[0037] Continue to refer to Figure 1 and Figure 2As shown, in the embodiment of the utility model, the side of the cavity cover 13 away from the speaker cavity 11 is the connection side, and the connection side includes two annular grooves, and the first positive terminal 21 and the first negative terminal 22 are respectively arranged in the annular grooves; the bottom of the annular groove includes a through-port, and the first positive terminal 21 and the first negative terminal 22 include a through-end, and the first positive terminal 21 and the first negative terminal 22 are respectively connected to the wiring harness through the through-end.

[0038] For example, the first positive terminal 21 and the first negative terminal 22 are connected to the annular groove by interference fit so that the two are tightly assembled, or they can be fixedly connected by bonding; or, for example, the surface of the first positive terminal 21 and the first negative terminal 22 is slightly higher than the annular groove.

[0039] Continue to refer Figure 1 and Figure 2 As shown, in the embodiment of the utility model, the speaker assembly 10 also includes a cavity partition wall 14, which is located between the speaker unit 12 and the cavity cover 13; the edge of the cavity partition wall 14 is in contact with the inner wall of the speaker cavity 11, so that the cavity partition wall 14 and the speaker cavity 11 form an independent effective chamber, and the cavity partition wall 14 is provided with a through hole for passing the wiring harness.

[0040] For example, the cavity partition wall 14 is movably connected to the inner wall of the speaker cavity 11, and is used to adjust the volume of the effective cavity. The cavity cover 13 is isolated by the cavity partition wall 14, so that the speaker unit 12 is in an independent effective cavity in the speaker cavity 11. For example, the edge of the cavity partition wall 14 abuts against the inner wall of the speaker cavity 11, and a sealing structure is provided, so that the cavity partition wall 14 can be kept in this position, and when the cavity partition wall 14 needs to be moved, the cavity partition wall 14 can be moved with the help of external force.

[0041] An embodiment of the utility model further provides a mainboard, comprising the above-mentioned speaker structure and a second magnetic terminal assembly 30 , wherein the speaker structure is connected to the second magnetic terminal assembly 30 via the first magnetic terminal assembly 20 .

[0042] like Figure 3 As shown, the second magnetic terminal assembly 30 includes a second positive terminal 31, a second negative terminal 32 and a second magnet 33, and the second positive terminal 31 and the second negative terminal 32 are respectively connected to the mainboard; when the first magnetic terminal assembly 20 is connected to the second magnetic terminal assembly 30, the first magnet 23 and the second magnet 33 attract each other, and the first positive terminal 21 is connected to the second positive terminal 31, and the first negative terminal 22 is connected to the second negative terminal 32.

[0043] For example, as shown in the figure, the second magnetic snap-in terminal assembly 30 and the first magnetic snap-in terminal assembly 20 have a symmetrical structure. The difference is that the magnetic poles on the opposite sides of the first magnet 23 and the second magnet 33 are opposite, so that the second magnetic snap-in terminal assembly 30 can be connected to the first magnetic snap-in terminal assembly 20.

[0044] For example, the second positive terminal 31 and the second negative terminal 32 are respectively connected to the wire harnesses. The other ends of the wire harnesses are connected to the connector, and can be connected to the main board through the connector. For example, the wire harnesses have a set length, and thus the second magnetic snap-in terminal assembly 30 has a higher degree of freedom and can be set at the desired position.

[0045] As Figure 4 shown, an embodiment of the present invention further provides an electronic product 40, including a housing 41 and the above-mentioned main board disposed in the housing 41. Taking the electronic product as a laptop computer as an example, it includes a system end and a display end. The main board is disposed in the housing 41 of the system end, and correspondingly, the speaker assembly 10 is also located at the system end.

[0046] For example, the side end of the housing 41 includes a sliding groove. The second magnetic snap-in terminal assembly 30 is disposed at the end of the sliding groove. The speaker structure is inserted into the sliding groove and is connected to the second magnetic snap-in terminal assembly 30 in the sliding groove through the first magnetic snap-in terminal assembly 20. Correspondingly, the part of the housing 41 forming the sliding groove is provided with sound holes for the cooperation of the speaker unit 12.

[0047] For example, the surface of the housing 41 includes a mounting position. The second magnetic snap-in terminal assembly 30 is disposed at the mounting position. The speaker structure abuts against the mounting position and is connected to the second magnetic snap-in terminal assembly 30 at the mounting position through the first magnetic snap-in terminal assembly 20.

[0048] That is to say, the position of the second magnetic snap-in terminal assembly 30 can be changed according to the usage requirements. For example, the sliding groove is disposed at the front end position of the system end, and the mounting position is disposed near the rotating shaft and on both sides. The speaker assemblies 10 are disposed at multiple positions simultaneously, which can make the sound field more diversified.

[0049] In addition, the orientation of the speaker assembly 10 can also be changed, that is, the sound output direction of the adjustable speaker unit 12 can be adjusted. Moreover, speakers with different sound field performances can be connected to the second magnetic snap-in terminal assembly 30 to meet the personalized setting of the sound field.

[0050] A loudspeaker structure, main board and electronic product 40 provided by the present utility model. The loudspeaker structure is fixed by a magnetic attraction method. Therefore, in its installation space, structures such as clamping components do not need to be provided, saving this part of the space. In addition, the magnetic attraction fixing method facilitates the replacement of the loudspeaker structure, and has less restriction on the installation position of the loudspeaker structure, making its installation more flexible. For example, it can be installed on the surface of the housing 41. In addition, the loudspeaker structure is an independent structure, avoiding affecting the efficacy of the loudspeaker structure due to space limitation. The technical solution of the present utility model modularizes the loudspeaker structure to ensure the function of the loudspeaker, enables variable matching combinations, makes the sound field more diversified, and can replace loudspeaker structures with different sound range performances to meet personalized configurations.
