The main body structure of the aforementioned speaker enclosure is complex, assembly is cumbersome, and the cost is high.

[0038] Please see Figures 1 to 4This application provides a speaker 100, including: a main body 10, a grille 20, a speaker 30, a cover plate 40, and a circuit board assembly 50; the main body 10 is an integrally formed structure, the main body 10 has an inner cavity 11, the main body 10 has a first wall surface 12 and a second wall surface 13, the first wall surface 12 has a first mounting opening 121, and the second wall surface 13 has a second mounting opening 131; the speaker 30 is embedded in the first mounting opening 121 and located in the inner cavity 11, the grille 20 is assembled on the first wall surface 12 and covers the sound output side of the speaker 30; the circuit board assembly 50 is disposed on the cover plate 40 and located in the inner cavity 11, and the cover plate 40 is assembled on the second wall surface 13 and covers the second mounting opening 131.

[0039] The speaker 100 provided in this embodiment differs from related technology speakers which use a front shell, rear shell, and outer shell to form the main body. The main body 10 of this embodiment adopts a one-piece molded structure. The first wall 12 of the main body 10 has a first mounting opening 121, and the second wall 13 has a second mounting opening 131, resulting in a simple structure. A speaker 30 is installed at the first mounting opening 121, and a grille 20 is assembled on the first wall 12 and covers the sound-emitting side of the speaker 30. A cover plate 40 is provided at the second mounting opening 131, and a circuit board assembly 50 is provided on the cover plate 40, located within the inner cavity 11 of the main body 10. Different components of the speaker 100 are easily assembled onto the main body 10, resulting in higher assembly efficiency and lower cost.

[0040] In some embodiments, please refer to Figure 3 , Figure 4 The main body 10 is a one-piece injection molded part. Injection molding is a fast and efficient production method that can be automated, produces precise product dimensions, and can produce products with complex shapes. In this embodiment, the main body 10 is a one-piece injection molded part, which can mass-produce complex-shaped main bodies 10. The main body 10 has a thin wall thickness and a robust structure.

[0041] For example, please refer to Figure 3 , Figure 4 The main body 10 is cylindrical. The first wall 12 of the main body 10 has a first mounting port 121, the second wall 13 has a second mounting port 131, and the inner wall of the main body 10 has various structural features such as reinforcing ribs 141.

[0042] In some embodiments, please refer to Figure 3 , Figure 4 The main body 10 is cylindrical. Setting the main body 10 in a cylindrical shape facilitates the arrangement of components such as the speaker 30 and circuit board assembly 50 within the inner cavity 11 of the main body 10. The cross-section of the main body 10 can be hexagonal, rectangular, or other shapes.

[0043] In some embodiments, please refer to Figure 4The inner wall of the main body 10 has reinforcing ribs 141. This makes the wall of the main body 10 thinner, the structure stronger, and improves the structural strength and stability of the main body 10.

[0044] For example, the main body 10 has a third wall 14 located between the first wall 12 and the second wall 13. The first wall 12 is provided with a speaker 30, the second wall 13 is provided with a circuit board assembly 50, and the third wall 14 serves as a support surface for the main body 10. The inner surface of the third wall 14 may be provided with horizontally and vertically distributed reinforcing ribs 141 to improve the structural strength of the main body 10.

[0045] In some embodiments, please refer to Figures 1 to 3 The grille 20 and the cover plate 40 can be assembled to the main body 10 using fasteners 20a and 40a respectively. Using fasteners facilitates the assembly of the grille 20 to the first wall surface 12 and the cover plate 40 to the second wall surface 13. The fasteners can be screws. When assembling the speaker 100 as a whole, fewer screws can be used to achieve overall assembly, resulting in high assembly efficiency.

[0046] For example, the edge of the mesh cover 20 is fixed to the first wall surface 12 by a plurality of first screws. The wall surface of the first wall surface 12 corresponding to the first screw can be thickened to deepen the first threaded hole corresponding to the first screw, so that the first screw is tightly connected to the first threaded hole and the locking force is increased.

[0047] For example, the edge of the cover plate 40 is fixed to the second wall 13 by a plurality of second screws. The wall of the second wall 13 corresponding to the second screw can be thickened to deepen the second threaded hole corresponding to the second screw, so that the second screw is tightly connected to the second threaded hole and the locking force is increased.

[0048] In some embodiments, please refer to Figures 1 to 3 The main body 10 has a third mounting port 15 at each end, and a passive radiator 31 is provided at each of the third mounting ports 15. The main body 10 also has end caps 32 at each end, which limit the range of motion of the passive radiator 31 and have sound outlets 321 for the passive radiator 31 to emit sound. The passive radiator 31 enhances bass response and improves sound quality. The end caps 32 can be assembled to the main body 10 using snap-fit ​​or tight-fitting methods.

[0049] A foot pad 33 can be installed at the bottom of the end cap 32 to make the speaker 100 stable on a support surface such as a desktop.

[0050] In some embodiments, please refer to Figure 3 The grille 20 is made of metal, such as aluminum or copper. Using a metal grille 20 allows the sound output from the speaker 30 to pass through the grille 20 and be output outwards, providing protection for the speaker 30 and a better appearance.

[0051] In some embodiments, please refer to Figure 3 The mesh cover 20 has multiple mesh openings 21, which are triangular, circular, or rectangular in shape. The shape of the mesh openings 21 of the mesh cover 20 can be set as needed.

[0052] For example, the mesh openings 21 of the mesh cover 20 are triangular, and multiple mesh openings 21 can be arranged in an array. Combined with Figure 2 The outer side of the cover plate 40 has triangular patterns. The triangular patterns and the triangular mesh 21 are similar in shape, giving the speaker 100 a better appearance.

[0053] In some embodiments, please refer to Figure 3 The thickness of the mesh area 21 of the grille 20 ranges from 0.8 mm to 1.2 mm. Setting the mesh area 21 to this thickness range facilitates the propagation of sound waves generated by the speaker 30 through the mesh area 21, resulting in minimal sound propagation loss. The thickness of the mesh area 21 of the grille 20 can be 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, etc., depending on the specific requirements.

[0054] In some embodiments, please refer to Figure 1 , Figure 3 The mesh cover 20 has ribs 22. The ribs 22 can improve the structural strength of the mesh cover 20, making the structure more robust and giving the mesh cover 20 a certain aesthetic appeal. The thickness of the ribs 22 can range from 1.2 mm to 1.6 mm, depending on the specific requirements, and minimizes sound propagation loss in the speaker 30.

[0055] In some embodiments, please refer to Figure 3 The mesh cover 20 is a sheet metal stamping part, and the mesh holes 21 of the mesh cover 20 are formed by stamping. When the mesh cover 20 has ribs 22, and the thickness of the ribs 22 is different from the thickness of the mesh hole area 21, the position of the ribs 22 can be directly formed by stamping, and the mesh hole area 21 can be obtained by CNC milling to a certain depth, so that the thickness of the ribs 22 and the thickness of the mesh hole area 21 are different.

[0056] In some embodiments, please refer to Figure 1 , Figure 3 There are two speakers 30, and the two speakers 30 are installed one-to-one in the two first mounting ports 121 on the first wall 12.

[0057] The first wall surface 12 may be provided with a surface layer 122 in the area between the two speakers 30, so that the surface layer 122 and the speakers 30 are both black, which has a better appearance.

[0058] When two speakers 30 are installed on the first wall 12 of the main body 10 and the cover plate 40 containing the circuit board assembly 50 is installed on the second wall 13 of the main body 10, the speakers 30 and the circuit board assembly 50 do not interfere with each other in terms of space, making full use of the space.

[0059] In some embodiments, please refer to Figure 3 , Figure 4 The inner side edge of the cover plate 40 is provided with an annular boss 41, and the second wall surface 13 is provided with an annular groove 132. The annular groove 132 is provided with a sealing layer. The annular boss 41 is provided in the annular groove 132, so that the sealing layer surrounds the annular boss 41 and the wall surface of the annular groove 132, thereby achieving a reliable seal between the cover plate 40 and the second mounting port 131 of the second wall surface 13.

[0060] In some embodiments, please refer to Figure 3 , Figure 5 The main body 10 is provided with a button circuit board 60, which has a button switch 61 and a first LED bead 62. The button circuit board 60 is provided with a light-shielding ring 63, which is sleeved on the first LED bead 62. The button circuit board 60 is covered with a flexible light-transmitting plate 64, which has a pressing position 641 corresponding to the button switch 61.

[0061] Users can control the speaker 100 by pressing the pressing position 641 on the flexible light-transmitting plate 64 to activate the button switch 61 on the button circuit board 60, such as turning it on / off, adjusting the volume, and switching between play / pause. The pressing position 641 of the flexible light-transmitting plate 64 can be textured or marked to indicate to the user.

[0062] The first LED chip 62 is encased in a light-shielding ring 63. The light emitted by the first LED chip 62 propagates through the inner hole of the light-shielding ring 63, and the light is concentrated and propagates outward. The first LED chip 62 can be a light-emitting diode (LED). The light-shielding ring 63 can be made of materials such as ethylene vinyl acetate (EVA) copolymer. The flexible light-transmitting plate 64 can be made of materials such as silicone.

[0063] For example, the button circuit board 60 and the flexible light-transmitting plate 64 can both be located on the top of the main body 10, that is, on the top between the first wall surface 12 and the second wall surface 13, so that the user can operate the button switch 61 of the button circuit board 60 to control the speaker 100.

[0064] In some embodiments, please refer to Figures 3 to 5The button circuit board 60 is disposed on the outer wall surface of the main body 10. The button circuit board 60 has a connector 65, which passes through the wall through hole 16 of the main body 10. A sealing layer 60a is provided between the button circuit board 60 and the outer wall surface of the main body 10. The sealing layer 60a extends along the edge of the through hole 16 and can achieve sealing between the button circuit board 60 and the wall surface of the main body 10.

[0065] In some embodiments, please refer to Figures 6 to 9 The circuit board assembly 50 includes a main board 51 and a first electrical connector 52. The main board 51 is disposed on the inner side of the cover plate 40, and the first electrical connector 52 is disposed on the first surface 51a of the main board 51. The cover plate 40 has a first opening 42 corresponding to the first electrical connector 52. The cover plate 40 is provided with a first sealing cover 70, which, in conjunction with... Figure 9 A sealing layer 70a is provided between the inner sides of the first sealing cover 70 and the cover plate 40, and between the first sealing cover 70 and the first surface 51a. The first sealing cover 70, the cover plate 40 and the first surface 51a together form a first receiving cavity 71. The first receiving cavity 71 is connected to the first opening 42. The first electrical connector 52 is located inside the first receiving cavity 71.

[0066] The first electrical connector 52 is used to connect to a matching device. For example, the first electrical connector 52 can be a USB Type-C interface, and the matching device is a data cable. Connecting the data cable to the first electrical connector 52 enables data transmission between the external device and the speaker 100, allowing external power to charge the internal battery 50a of the speaker 100. The first electrical connector 52 can also be a card slot or other data interface, etc.

[0067] Resistors, capacitors, chips, and other components can be installed on the motherboard 51. The inner and outer sides of the cover plate 40 face away from each other. When the cover plate 40 is assembled into the housing 10 of the speaker 100, the inner side of the cover plate 40 is the side that cannot be seen by the user.

[0068] The first electrical connector 52 is disposed in the first receiving cavity 71 formed by the first sealing cover 70, the cover plate 40, and the first surface 51a. Sealing layers 70a are respectively provided between the inner surfaces of the first sealing cover 70 and the cover plate 40, and between the first sealing cover 70 and the first surface 51a. The rear of the speaker 30 is located within the inner cavity 11 of the main body 10. The air inside the inner cavity 11 is isolated from the external space, preventing air from flowing outwards and preventing sound leakage through the first receiving cavity 71 and the first opening 42, thus reducing the power loss of the speaker 100 and improving the sound quality of the speaker 100. The combination of the first sealing cover 70 and the sealing layer 70a also prevents external water from entering the inner cavity 11 through the first opening 42, providing a waterproof function. The aforementioned sealing layer 70a can be made of materials such as EVA copolymer, which is easy to mold and has a good sealing effect.

[0069] In some embodiments, please refer to Figure 8 , Figure 9 The motherboard 51 and the cover plate 40 are arranged perpendicularly. The inner side space of the cover plate 40 is fully utilized to arrange components on the motherboard 51, and other components (such as battery 50a) are arranged on the inner side of the cover plate 40. When the motherboard 51 is mounted on the cover plate 40, the electrical connectors on the motherboard 51 are arranged to correspond to the openings of the cover plate 40.

[0070] In some embodiments, please refer to Figure 7 The inner side of the cover plate 40 has a positioning groove 43, and one edge of the motherboard 51 is inserted into the positioning groove 43. This facilitates the positioning and assembly of the motherboard 51 on the cover plate 40, keeps the motherboard 51 in the predetermined position, and improves assembly efficiency.

[0071] In some embodiments, please refer to Figure 8 The inner side of the cover plate 40 is provided with fasteners 51c for fixing the motherboard 51 to the cover plate 40. The use of fasteners 51c can reliably fix the motherboard 51 to the cover plate 40 and facilitates assembly.

[0072] For example, fastener 51c may include a screw and a washer, with the screw threaded onto cover 40 after passing through the washer. The washer abuts against mainboard 51, securing mainboard 51 to cover 40.

[0073] In some embodiments, please refer to Figures 7 to 9 The circuit board assembly 50 also includes a second electrical connector 53, which is disposed on the second surface 51b of the motherboard 51. The first surface 51a and the second surface 51b are opposite to each other. The cover plate 40 has a second opening 44 corresponding to the second electrical connector 53. The cover plate 40 is provided with a second sealing cover 80. A sealing layer 80a is provided between the inner side of the second sealing cover 80 and the cover plate 40, and between the second sealing cover 80 and the second surface 51b. The second sealing cover 80, the cover plate 40 and the second surface 51b together form a second receiving cavity 81. The second receiving cavity 81 is connected to the second opening 44. The second electrical connector 53 is located in the second receiving cavity 81.

[0074] The second electrical connector 53 is used to connect to a matching device. For example, the second electrical connector 53 can be a trans-flash (TF) card slot, and the matching device is a TF card. When the TF card is inserted into the second electrical connector 53, the speaker 100 can read the data on the TF card to play audio. The first electrical connector 52 and the second electrical connector 53 are arranged on different surfaces of the motherboard 51, with a compact structure, facilitating the assembly of the first sealing cover 70 and the second sealing cover 80 onto the inner side of the cover plate 40. The second electrical connector 53 can also be used for other data interfaces.

[0075] The second electrical connector 53 is disposed in the second receiving cavity 81 formed by the second sealing cover 80, the cover plate 40, and the second surface 51b. Sealing layers 80a are respectively provided between the inner surfaces of the second sealing cover 80 and the cover plate 40, and between the second sealing cover 80 and the second surface 51b. The rear of the speaker 30 is located within the inner cavity 11 of the main body 10. The air inside the inner cavity 11 is isolated from the external space, preventing air from flowing outwards and preventing sound leakage through the second receiving cavity 81 and the second opening 44, thus reducing the power loss of the speaker 100 and improving the sound quality of the speaker 100. The combination of the second sealing cover 80 and the sealing layer 80a also prevents external water from entering the inner cavity 11 through the second opening 44, providing a waterproof function. The aforementioned sealing layer 80a can be made of materials such as EVA copolymer, which is easy to mold and has a good sealing effect.

[0076] In some embodiments, please refer to Figure 3 , Figure 6 , Figure 7 The first sealing cover 70 is fixed to the cover plate 40 by fasteners, and the second sealing cover 80 is fixed to the main board 51 and the first sealing cover 70 by fasteners. Fasteners are used to assemble the first sealing cover 70 and the second sealing cover 80 onto the cover plate 40, thus securing the main board 51, the first sealing cover 70, the second sealing cover 80, and the cover plate 40 together. The fasteners can be screws.

[0077] For example, the first sealing cover 70 and the cover plate 40 can be fixedly connected by two screws. The second sealing cover 80 and the first sealing cover 70 are fixedly connected by two screws, which pass through the main board 51, so that both the main board 51 and the second sealing cover 80 are fixed to the first sealing cover 70.

[0078] In some embodiments, please refer to Figures 7 to 9 The inner surface of the cover plate 40 has a limiting groove 45, and a portion of the edge of the first sealing cover 70 and a portion of the edge of the second sealing cover 80 are inserted into the limiting groove 45. This allows the first sealing cover 70 and the second sealing cover 80 to be positioned on the cover plate 40 along its surface. It also facilitates the installation of a sealing layer within the limiting groove 45, achieving a tight connection between the first sealing cover 70 and the cover plate 40, and between the second sealing cover 80 and the cover plate 40.

[0079] In some embodiments, please refer to Figures 6 to 9 The edge of the first sealing cover 70, which is connected to the first surface 51a, has a first filling groove 72, and the edge of the second sealing cover 80, which is connected to the second surface 51b, has a second filling groove 82. The sealing layer can fill the first filling groove 72 and the second filling groove 82, so that the edges of the first surface 51a and the first sealing cover 70 of the motherboard 51, and the edges of the second surface 51b and the second sealing cover 80 of the motherboard 51 are tightly connected.

[0080] In some embodiments, please refer to Figure 6 , Figure 9 It also includes a plug 90, which is detachably installed in the slot 47 of the cover plate 40. When the plug 90 is installed in the slot 47, it covers the first opening 42 and the second opening 44, thus providing waterproof protection for the electrical connector. When the plug 90 is removed from the cover plate 40, it is convenient for the user to insert the corresponding device into the electrical connector.

[0081] For example, the stopper 90 may be made of an elastic material such as silicone. The stopper 90 may have a connecting buckle 91 that engages with the cover plate 40 to hold the stopper 90 in the vicinity of the cover plate 40.

[0082] In some embodiments, please refer to Figures 7 to 9 The inner side of the cover plate 40 has a battery slot 46, in which a battery 50a is disposed. The battery 50a is electrically connected to the main board 51. The first sealing cover 70 is disposed opposite to the battery 50a so that the battery 50a is confined in the battery slot 46. Placing the battery 50a in the battery slot 46 and confining it to the inner side of the cover plate 40 by the first sealing cover 70 makes the battery 50a easy to assemble and improves assembly efficiency.

[0083] In some embodiments, please refer to Figures 6 to 8 The main board 51 has a light-emitting circuit board 54 at one end, which is perpendicular to the main board 51 and electrically connected to it. The light-emitting circuit board 54 has a second LED bead 541. Assembling the light-emitting circuit board 54 onto the main board 51 to achieve electrical connection results in a simple structure and low cost. The second LED bead 541 can be an LED bead.

[0084] The main board 51 and the light-emitting circuit board 54 are integrated into one structure. The main board 51 is installed on the inner side of the cover plate 40, and the cover plate 40 is assembled at the second mounting port 131 of the main body 10. This allows the second lamp bead 541 to be arranged in the center of the third mounting port 15 of the main body 10, resulting in better light emission effect of the second lamp bead 541.

[0085] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
