Description

Technical Field

[0001] The invention belongs to the technical field of sound boxes, and in particular relates to a box body and a sound box. Background Art

[0002] With the development of technology and the improvement of living standards, the public's pursuit of the quality of speaker products is getting higher and higher. They not only want to listen to music through speakers, but also want to listen to pure and real sounds through speakers.

[0003] For speaker products, when the speaker diaphragm is working, compressed air will be generated inside the box. This compressed air will force the diaphragm to vibrate in the opposite direction. When playing low-frequency music, the vibration amplitude of the speaker diaphragm is too large, which can easily cause the speaker shell to resonate and generate noise or murmurs. Summary of the invention

[0046] With the development of technology and the improvement of living standards, the public's pursuit of the quality of speaker products is getting higher and higher. They not only want to listen to music through speakers, but also want to listen to pure and real sounds through speakers.

[0047] For speaker products, when the speaker diaphragm is working, compressed air will be generated inside the box. This compressed air will force the diaphragm to vibrate in the opposite direction. When playing low-frequency music, the vibration amplitude of the speaker diaphragm is too large, which can easily cause the speaker housing to resonate, causing noise or murmurs. To solve such problems, the existing technology usually reduces the resonance phenomenon and lowers the resonance frequency by thickening the speaker housing or adding reinforcement plates, thereby improving the quality of the speaker. However, thickening the box housing not only makes the product bulky and increases the cost, but also reduces the acoustic volume. Although adding reinforcement plates can reduce the resonance phenomenon and increase the weight of the box to a small extent, in actual products, the space inside the box usually cannot accommodate the reinforcement plates connecting the four side walls, and the reinforcement plates are not conducive to the transmission of sound waves in the box.

[0048] Figure 1 The structure diagram of the speaker 100 according to the embodiment of the present invention is schematically shown. Figure 8 for Figure 1 A schematic diagram of the structure of the reinforcement structure 20 of the middle speaker 100. Figure 1 and 8 As shown, the present invention proposes a box and a speaker 100. The box in the present invention includes a box body 10 and a reinforcement structure 20, wherein the box body 10 has a receiving cavity 15, and the receiving cavity 15 has a first inner wall 11 and a second inner wall 12 arranged oppositely, and the reinforcement structure 20 includes at least one reinforcement member, and the opposite ends of the reinforcement member are respectively connected to the first inner wall 11 and the second inner wall 12, and a channel is defined in the reinforcement member, and the channel extends from the first inner wall 11 to the second inner wall 12.

[0049] The box body according to the present invention can improve the strength between the first inner wall 11 and the second inner wall 12, thereby improving the strength of the entire box body. When the speaker of the sound box 100 is operating, it is easy to cause the vibration amplitude of the diaphragm of the sound box 100 to be too large, thereby causing the box body to resonate. However, since the strength of the box body is improved by the reinforcement structure 20, the influence of the speaker on the resonance of the box body can be reduced, thereby improving reliability. At the same time, since a channel is defined in the reinforcement part, the weight of the reinforcement structure 20 can be reduced, and it basically does not block or change the gas flow inside the box body, thereby ensuring both the strength of the box body and the lightness of the box body.

[0050] In some embodiments of the present invention, Figure 8 and 9As shown, the reinforcing member includes a plurality of columnar portions 231, which are arranged in an annular manner at intervals and define a channel, and the opposite ends of each columnar portion 231 are respectively connected to the first inner wall 11 and the second inner wall 12. In this embodiment, the reinforcing member is provided with a plurality of columnar portions 231, which are arranged in an annular manner at intervals, and can support the first inner wall 11 and the second inner wall 12, thereby improving the strength between the first inner wall 11 and the second inner wall 12, and reducing the influence of the speaker on the resonance of the box body, thereby improving reliability.

[0051] In some embodiments of the present invention, Figure 8 and 9 As shown, multiple columnar portions 231 are arranged parallel to each other. In this embodiment, the axial direction of the columnar portion 231 is perpendicular to the arrangement direction of the first inner wall 11 and the second inner wall 12, and the multiple columnar portions 231 are parallel to each other, which can better support the first inner wall 11 and the second inner wall 12, thereby providing better support performance and reducing the resonance effect on the box when the speaker is operating. In addition, the distance between two adjacent columnar portions 231 is the same, which can make the bearing force of the reinforcement structure 20 between the first inner wall 11 and the second inner wall 12 more uniform, thereby improving the service life of the reinforcement structure 20.

[0052] In some embodiments of the present invention, Fig. 9 As shown, the column part 231 is a cylindrical structure, and the setting range of the diameter of the column part 231 is 0.2mm-20mm. In this embodiment, the column part 231 is a cylinder. The larger the diameter of the cylinder, the larger the volume, which ultimately makes the strength of the reinforcing piece greater, but the larger the volume is, the better. A balance needs to be achieved between the diameter of the column part 231 and the lightweight of the reinforcing structure 20. It can be seen from the simulation that the reinforcing piece with the value range of the diameter of the column part 231 set above can meet the requirements of box reinforcement and the requirements of sound wave transmission inside the box, thereby improving reliability.

[0053] In some embodiments of the present invention, Fig. 9 As shown, along the axis direction of the column part 231, the length of the column part 231 is set in the range of 10mm-1000mm. In this embodiment, the column part 231 is a cylinder, and the height of the cylinder depends on the distance between the first inner wall and the second inner wall. It can be seen from the simulation that the reinforcing member with the above-set length range of the column part 231 can meet the requirements of box reinforcement and the requirements of sound wave transmission inside boxes of different sizes, thereby improving reliability.

[0054] In some embodiments of the present invention, the number of column parts 231 is set in a range of 2 to 80. In this embodiment, the more the number of cylinders, the denser the enclosed annular structure, and the larger the volume, which ultimately makes the strength of the reinforcing member greater, but the larger the volume is, the better. A balance needs to be achieved between the number of column parts 231 and the lightweight of the reinforcing structure 20. It can be seen from the simulation that the reinforcing member with the value range of the number of column parts 231 set above can meet the requirements of box reinforcement and the requirements of sound wave transmission inside the box, thereby improving reliability.

[0055] In some embodiments of the present invention, the reinforcing structure 20 further includes a first end 21 and a second end 22, and the opposite ends of the reinforcing member are respectively connected to the first end 21 and the second end 22, and the first end 21 and the first inner wall 11 are detachably connected, and the second end 22 and the second inner wall 12 are detachably connected. In this embodiment, the opposite ends of the reinforcing member are respectively connected to the first inner wall 11 and the second inner wall 12 through the first end 21 and the second end 22, and the first end 21 and the second end 22 are respectively detachably connected to the first inner wall 11 and the second inner wall 12, which can facilitate the disassembly and installation of the reinforcing structure 20 and the box.

[0056] Specifically, in this embodiment, one end of the multiple column portions 231 is connected to the outermost circle of the first end portion 21 on the side away from the first inner wall 11, and the other end of the multiple column portions 231 is connected to the outermost circle of the second end portion 22 on the side away from the second inner wall 12. This arrangement can maximize the action surface between the multiple column portions 231 and the first inner wall 11 through the first end portion 21, and can also maximize the action surface between the multiple column portions 231 and the second inner wall 12 through the second end portion 22. Since the action surface is proportional to the action force, that is, a large action surface can support the first inner wall 11 or the second inner wall 12 in a wider range, further improving the support stability and the strength between the first inner wall 11 and the second inner wall 12.

[0057] In some embodiments of the present invention, Figure 8 and 9As shown, the reinforcing member further includes a spiral portion 232, which spirally extends along the axis direction of the column portion 231, and the opposite ends of the spiral portion 232 along the axis direction of the column portion 231 are respectively connected to the first inner wall 11 and the second inner wall 12, and a plurality of column portions 231 are provided with spiral portions 232 along their own axis directions. In this embodiment, the spiral portion 232 is connected between the first end portion 21 and the second end portion 22, which can support the first inner wall 11 and the second inner wall 12, thereby improving the strength between the first inner wall 11 and the second inner wall 12, and reducing the influence of the speaker on the resonance of the box body, thereby improving reliability. In addition, the spiral portions 232 are arranged along the axial direction of the multiple column portions 231, so that the spiral portions 232 and the multiple column portions 231 are connected, and the spiral portions 232 and the multiple column portions 231 are both connected to the first inner wall 11 and the second inner wall 12. When the speaker vibrates the box, the strength of the spiral portions 232 and the strength of the multiple column portions 231 can affect each other, thereby further improving the supporting strength between the first inner wall 11 and the second inner wall 12.

[0058] Specifically, in this embodiment, the reinforcement part also includes a circular ring portion, and a plurality of circular ring portions are provided. The plurality of circular ring portions are spaced apart along the axial direction of the column portion, and each column portion is respectively provided with a plurality of circular ring portions in sequence along the axial direction of the column portion. This embodiment can also connect the plurality of column portions. When the speaker vibrates the box, the strength of the plurality of circular ring portions and the plurality of column portions can influence and enhance each other, thereby further improving the supporting strength between the first inner wall and the second inner wall.

[0059] Specifically, in this embodiment, the spiral portion 232 connects the multiple column portions 231 together to ensure the radial strength of the annular structure formed by the multiple column portions 231, thereby improving the supporting strength between the first inner wall 11 and the second inner wall 12, and ultimately reducing the impact of the speaker on the resonance of the box.

[0060] In some embodiments of the present invention, Fig. 9As shown, the volume of the column portion 231 is a, the number of the column portions 231 is N, the volume of the spiral portion 232 is b, the first end portion 21 and the second end portion 22 are both first circular plate structures, and the diameters of the first end portion 21 and the second end portion 22 are both D, and the length of the column portion 231 along its own axis direction is L, wherein N*a+b=(5%-25%)*π*(D / 2)2*L. In this embodiment, the left side of the above formula is the sum of the volumes of the plurality of column portions 231 and a spiral portion 232, and the π*(D / 2)2*L on the right side of the above formula is the volume formed between the first end portion 21 and the second end portion 22. The above formula indicates that the sum of the volumes of the plurality of column portions 231 and a spiral portion 232 is 5%-25% of the volume formed between the first end portion 21 and the second end portion 22.

[0061] Specifically, in this embodiment, the larger the sum of the volumes of the multiple column portions 231 and a spiral portion 232, the larger the composed volume is, and ultimately the strength of the reinforcement is greater. However, the larger the volume is, the better. A balance needs to be achieved between the volume and lightweight of the reinforcement structure 20. From the simulation, it can be seen that the formula relationship N*a+b=(5%-25%)*π*(D / 2)2*L can meet the needs of box reinforcement, the needs of sound wave transmission inside the box, and the needs of lightweight of the reinforcement structure 20.

[0062] In some embodiments of the present invention, Fig. 9 As shown, the pitch of the spiral portion 232 is set in the range of 0.5mm-100mm. In this embodiment, the smaller the pitch of the spiral portion 232, the denser the spiral portion 232 is, and the larger the volume is, which ultimately makes the strength of the reinforcing member greater, but the larger the volume is, the better. A balance needs to be achieved between the pitch of the spiral portion 232 and the lightweight of the reinforcing structure 20. It can be seen from the simulation that the reinforcing member with the value range of the length of the column portion 231 set above can meet the requirements of box reinforcement and the requirements of sound wave transmission inside the box, thereby improving reliability.

[0063] In some embodiments of the present invention, a plurality of spiral portions 232 are provided, and the plurality of spiral portions 232 are spaced apart along the axial direction of the column portion 231. In this embodiment, a plurality of spiral portions 232 may be provided, so that the plurality of spiral portions 232 and the plurality of column portions 231 are connected, and the plurality of spiral portions 232 and the plurality of column portions 231 are both connected to the first inner wall 11 and the second inner wall 12. When the speaker vibrates the box, the strength of the plurality of spiral portions 232 and the strength of the plurality of column portions 231 can affect each other, thereby further improving the support strength between the first inner wall 11 and the second inner wall 12.

[0064] In some embodiments of the present invention, Fig. 9As shown, the first end 21 and the second end 22 are both second circular plate structures, and the diameters of the first end 21 and the second end 22 are 1.5-300mm. In this embodiment, the first end 21 and the second end 22 are both circular plate structures. The larger the diameter of the circular plate structure, the larger the contact surface with the first inner wall 11 and the second inner wall 12. The large effective surface can support the first inner wall 11 or the second inner wall 12 in a wider range. However, the diameter of the circular plate structure is not the larger the better. A balance needs to be achieved between the diameter of the first end 21 and the second end 22 and the lightweight of the reinforcement structure 20. It can be seen from the simulation that the reinforcement member with the value range of the diameter of the circular plate structure set above can meet the requirements of box reinforcement and the requirements of sound wave transmission inside the box, thereby improving reliability.

[0065] In some embodiments of the present invention, Figure 4 , 5 As shown in Figures 9 and 10 , a fixing portion 24 is provided on one side of the first end portion 21 facing the first inner wall 11 and / or on one side of the second end portion 22 facing the second inner wall 12, a groove 111 provided along a second direction is provided on one side of the first inner wall 11 facing the first end portion 21 and / or on one side of the second inner wall 12 facing the second end portion 22, and the fixing portion 24 can be slidably provided in the groove 111 along the second direction, and the second direction is perpendicular to the arrangement direction of the first inner wall 11 and the second inner wall 12. In this embodiment, the fixing portion 24 is provided on the first end portion 21 and the second end portion 22, respectively, and the groove 111 is provided on the first inner wall 11 and the second inner wall 12, respectively, and the two fixing portions 24 at both ends of the reinforcement structure 20 can slide along the second direction through the two grooves 111 of the first inner wall 11 and the second inner wall 12, thereby adjusting the position of the reinforcement structure 20 in the accommodating cavity 15, and thereby increasing the support strength at a specific position.

[0066] Specifically, in this embodiment, if Figure 2 , 3 As shown in Figures 6 and 7, the accommodating cavity 15 also includes a third inner wall 13 and a fourth inner wall 14. The first inner wall 11, the third inner wall 13, the second inner wall 12 and the fourth inner wall 14 are connected in sequence, and the third inner wall 13 is detachably connected to the first inner wall 11 and the second inner wall 12 respectively. The first inner wall 11 is provided with a first opening 121, and the first opening 121 is used to fix the speaker.

[0067] In some embodiments of the present invention, the groove 111 has an abutting wall on one side along the second direction, and the abutting wall can abut against the fixing portion 24. In this embodiment, one end of the groove 111 along the second direction is an open structure, and the third inner wall 13 can be covered on the open structure to close the open structure. Since the third inner wall 13 is detachable, the two fixing portions 24 of the reinforcement structure 20 can enter the two grooves 111 through the opening structure of the groove 111, thereby realizing the sliding of the reinforcement structure 20 in the groove 111 along the second direction. The other end of the groove 111 along the second direction has an abutting wall, and the abutting wall is used to abut against the fixing portion 24, thereby realizing the positioning function of the reinforcement structure 20. In this embodiment, the fixing portion 24 of the reinforcement structure 20 and the groove 111 are interference fit, and even if there is no fixing portion 24, it can be fixed at various positions of the groove 111 along the second direction. The setting of the abutting wall can more conveniently slide the fixing portion 24 to a fixed position, thereby realizing the positioning operation.

[0068] In some embodiments of the present invention, Figure 8 and 9 As shown, the fixing portion 24 is provided with a first fixing hole 241, and the abutting wall is provided with a second fixing hole, and the first fixing hole 241 and the second fixing hole are used for the fixing member to penetrate, so as to fix the fixing portion 24 on the abutting wall. In this embodiment, the fixing member can be a fixing portion 24 such as a bolt, which can penetrate the first fixing hole 241 and the second fixing hole in sequence, thereby achieving the fixing operation of fixing the fixing portion 24 on the abutting wall, further improving the stability between the reinforcement structure 20 and the box body.

[0069] The present invention adds a reinforcement structure 20 inside the box of the speaker 100 to increase the strength of the box, and the reinforcement structure 20 is composed of a spiral portion 232 and a column portion 231, which can solve the resonance phenomenon of the box, occupies a small acoustic volume in the box, and will not block the transmission of sound waves in the box.

[0070] Furthermore, the cylindrical portion 231 and the spiral portion 232 of the box of the present invention have a relatively smooth shape, occupy a small area in any cross section, and have less obstruction to the airflow inside the box. The cylindrical portion 231 and the spiral portion 232 have a small volume, occupy a small acoustic volume in the box, and can leave a larger acoustic volume in the box, obtain better sound effects, and deliver pure and real sound.

[0071] Furthermore, the diameter and number of the column part 231 and the pitch size of the spiral part 232 in the reinforcement structure 20 can be reduced by replacing materials with higher strength. Under the condition that the degree of reinforcement of the box body remains unchanged, the volume of the reinforcement structure 20 becomes smaller, which is more conducive to the transmission of sound waves inside the box body. For example, CF-PEEK material (carbon fiber / polyetheretherketone composite material) or metal material is used as a whole, and continuous carbon fiber material is added to the column part 231 and the spiral part 232. The size of the reinforcement structure 20 can be flexibly adjusted according to the size of the box body, and the application scenarios are relatively wide.

[0072] The present invention also provides a speaker 100, such as Figure 2 and 3 As shown, including:

[0073] speaker;

[0074] The box body has a first opening 121 in the receiving cavity 15 of the box body. The speaker is arranged at the first opening 121. The first opening 121 is perpendicular to the arrangement direction of the first inner wall 11 and the second inner wall 12. The box body is the above-mentioned box body. The first opening 121 is perpendicular to the axial direction of the reinforcement structure 20.

[0075] The cabinet of the sound box 100 according to the present invention can improve the strength between the first inner wall 11 and the second inner wall 12, thereby improving the strength of the entire cabinet. When the speaker of the sound box 100 is operating, it is easy to cause the vibration amplitude of the diaphragm of the sound box 100 to be too large, thereby causing the cabinet to resonate. However, since the strength of the cabinet is improved by the reinforcement structure 20, the influence of the speaker on the resonance of the cabinet can be reduced, thereby improving reliability. At the same time, since a channel is defined in the reinforcement part, the weight of the reinforcement structure 20 can be reduced, and it basically does not block or change the gas flow inside the cabinet, thereby ensuring both the strength of the cabinet and the lightness of the cabinet.

[0076] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
