Description

Technical Field

[0001] This application belongs to the technical field of electronic products, and more specifically, relates to a speaker housing and a speaker. Background Technology

[0002] To win over users, some audio products are designed with cylindrical or other irregular shapes with curved bottoms to improve their aesthetics, blend them into the home environment, effectively disperse sound waves, and improve sound quality, thus satisfying users' dual pursuit of beauty and practicality.

[0003] However, when cylindrical or other curved speakers are placed horizontally, the curvature of their bottom surface reduces their stability, making them prone to rolling on the table. While support structures such as feet can be installed on the outside of the speaker to maintain its position, this compromises the speaker's overall appearance, and the feet also risk detaching and becoming unusable. Utility Model Content

[0004] The purpose of this application is to provide a speaker housing and a speaker to solve the problem of poor placement stability of speakers with curved bottom surfaces in the prior art.

[0005] To achieve the above objectives, in a first aspect, this application provides a speaker housing, including a housing and an eccentric structure disposed on the housing; the housing has a first cavity, and the bottom surface of the housing is an arc-shaped surface; the eccentric structure includes a movable counterweight, the movable counterweight being a liquid or multiple granular solids, and the movable counterweight partially filling the first cavity.

[0006] In some embodiments of the first aspect, the eccentric structure further includes two counterweights disposed on the bottom cavity wall of the first cavity, the two counterweights being arranged at intervals and forming a positioning groove between the two counterweights, the movable counterweight being able to be fully received in the positioning groove.

[0007] In some embodiments of the first aspect, the top surface of the counterweight is inclined relative to the horizontal plane and faces the center of the positioning groove.

[0008] In some embodiments of the first aspect, the eccentric structure further includes a positioning block disposed at the bottom of the positioning groove and spaced apart from the two counterweights.

[0009] In some embodiments of the first aspect, the top of the positioning block is lower than the lowest point of the top surface of the counterweight block.

[0010] In some embodiments of the first aspect, the housing further has a second cavity isolated from the first cavity, the second cavity being used to mount an electronic module for an audio device.

[0011] In some embodiments of the first aspect, the housing includes: a cylindrical body, a partition, and a cover plate; the cylindrical body is a hollow cylinder, the partition is disposed inside the cylindrical body, and the cover plate is disposed on the cylindrical body and closes one of the openings of the cylindrical body; the surface of the partition facing the cover plate, the inner surface of the cylindrical body, and the surface of the cover plate facing the partition plate together form the first cavity; the surface of the partition facing away from the cover plate and the inner surface of the cylindrical body together form the second cavity.

[0012] In some embodiments of the first aspect, the cylinder and the partition are integrally formed, and the cylinder and the cover are detachably connected.

[0013] In some embodiments of the first aspect, there are two first cavities symmetrically arranged on both sides of the second cavity, and each first cavity is provided with the eccentric structure.

[0014] Secondly, this application also provides an audio speaker, including an audio speaker housing as described in the first aspect and any alternative embodiments thereof, and an electronic module mounted on the audio speaker housing.

[0015] The beneficial effects of the speaker housing and speaker provided in this application are as follows: By setting a movable counterweight inside the first cavity of the speaker housing, the movable counterweight is a liquid or multiple granular solids. Under natural conditions, the movable counterweight can accumulate at the bottom cavity wall of the first cavity, thereby using the gravity of the movable counterweight to lower the center of gravity of the speaker housing, making the center of gravity of the speaker housing closer to the curved bottom surface, so that the speaker maintains a stable position during use and is not easy to tip over or roll due to vibration. There is no need to set up support structures such as feet, thus improving the overall aesthetics of the speaker housing. Attached Figure Description

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0029] In a first aspect, embodiments of this application provide a speaker housing, such as... Figure 1 and Figure 2As shown, the speaker housing includes a housing 100 and an eccentric structure 200 disposed on the housing 100; the housing 100 has a first cavity 101, and the bottom surface of the housing 100 is an arc-shaped surface; the eccentric structure 200 includes a movable counterweight 210, which is a liquid or multiple granular solids, and the movable counterweight 210 partially fills the first cavity 101.

[0030] Specifically, the housing 100 can be made of metallic or non-metallic materials and provides a mounting location for the eccentric structure and the audio electronic modules. The housing 100 can be a cylindrical structure with a circular, elliptical, or at least arc-shaped bottom cross-section. In use, the housing 100 is placed horizontally, making its bottom surface arc-shaped. The arc-shaped outer surface of the housing 100 not only enhances the overall aesthetics of the audio system but also contributes to the even diffusion of sound and enhances the bass response.

[0031] The first cavity 101 is a hollow structure disposed inside the housing 100, used to house the eccentrically oriented movable counterweight 210 inside the housing 100, preventing the movable counterweight 210 from overflowing from the housing 100. When the housing 100 is placed horizontally, the first cavity 101 can be disposed at one end of the housing 100 along its axial direction. The shape of the first cavity 101 can be arbitrary; for example, the outline of the first cavity 101 can be a circle coaxial with the housing 100.

[0032] The eccentric structure 200 includes a movable counterweight 210 disposed within the first cavity 101. The movable counterweight 210 can be a liquid, such as water, oil, or other stable solutions; it can also be multiple granular solids, such as fine sand, metal powder, or a large number of metal spheres. The volume of the movable counterweight 210 should be less than the total volume of the first cavity 101; for example, the volume of the movable counterweight 210 is 25% to 30% of the volume of the first cavity 101. Under gravity, the movable counterweight 210 will naturally accumulate at the bottom of the first cavity 101, thereby lowering the center of gravity of the entire speaker enclosure. Without additional feet or other support structures, this allows the speaker enclosure to remain stable and prevents it from rolling due to vibration or external forces, thus facilitating optimized design of the speaker enclosure's shape and balancing practicality and aesthetics.

[0033] Furthermore, the movable counterweight 210 not only lowers the overall center of gravity of the speaker housing, but also causes the housing 100 to wobble or roll on the table due to its curved bottom surface when the user applies a certain amount of force to it. At this time, the movable counterweight 210 within the first cavity 101 flows within the cavity as the housing 100 moves, creating a natural damping effect. This causes the housing 100 to oscillate irregularly with the movement of the movable counterweight 210, eventually stabilizing as the movable counterweight 210 recoils back to the bottom of the first cavity 101. This endows the speaker with certain entertainment functions, further enhancing the user experience.

[0034] In some embodiments, the eccentric structure 200 further includes two counterweights 220 disposed on the bottom cavity wall of the first cavity 101. The two counterweights 220 are arranged at intervals and a positioning groove is formed between the two counterweights 220. The movable counterweight 210 can be fully accommodated in the positioning groove.

[0035] The counterweight 220 can be made of a high-density metal or non-metal material. The shape of the counterweight 220 can be arbitrary; for example, it can be a triangular block with its bottom surface being an arc surface that matches the inner surface of the first cavity 101. The bottom of the counterweight 220 is fixed to the inner bottom surface of the first cavity 101. When the first cavity 101 is circular, the counterweight 220 should be located below the axis of the first cavity 101. The two counterweights 220 can be arranged symmetrically based on a vertical plane passing through the axis of the housing 100, so that the overall center of gravity of the two counterweights 220 and the axis of the housing 100 are located on the same vertical plane. Of course, their relative positions can also be adapted to different outer surface shapes of the housing 100.

[0036] The counterweights 220 should abut against the two inner surfaces of the first cavity 101 along the axial direction at their two end faces on the housing 100. This creates a positioning groove formed by the two counterweights 220 and the inner surfaces of the first cavity 101 along the axial direction. The volume of the positioning groove is not less than the volume of the movable counterweights 210, ensuring that all movable counterweights 210 are accommodated within it. This limits the movement range of the movable counterweights 210 when the housing 100 is subjected to external forces, preventing excessive shaking of the movable counterweights 210 and ensuring the speaker housing remains balanced. It also facilitates the rapid return of the movable counterweights 210 to the bottom of the first cavity 101 after shaking, allowing the speaker housing to quickly regain stability and further enhancing user interaction. Furthermore, the two counterweights 220 are positioned near the bottom of the housing 100, which also helps to lower the center of gravity of the speaker housing.

[0037] like Figure 3 and Figure 4 As shown, in some embodiments, the top surface of the counterweight 220 is inclined relative to the horizontal plane and faces the center of the positioning groove.

[0038] Specifically, one end of the top surface of the counterweight 220 is attached to the inner surface of the first cavity 101, and the other end is inclined downward to guide the flow direction of the movable counterweight 210 when it flows in the first cavity 101, so that the movable counterweight 210 can be reset to the positioning groove along the inclined surface, and also to avoid leaving the movable counterweight 210 on the top of the counterweight 220, thus ensuring the stability of the center of gravity.

[0039] In addition, the counterweight 220 can be designed in different shapes and sizes to increase the diversity of the movement of the movable counterweight 210 within the first cavity 101, so that the speaker shell can exhibit different stability effects when subjected to external forces, bringing users a richer interactive experience.

[0040] In some embodiments, the eccentric structure 200 further includes a positioning block 230, which is disposed at the bottom of the positioning groove and spaced apart from the two counterweights 220.

[0041] The positioning block 230 can also be made of a high-density metal or non-metal material. The shape of the positioning block 230 can be arbitrary; for example, it can be a trapezoidal structure with dimensions gradually increasing from top to bottom, and its bottom surface can be an arc surface that matches the shape of the inner surface of the first cavity 101, allowing the bottom surface of the positioning block 230 to fit tightly against the inner bottom surface of the first cavity 101. The positioning block 230 can be located in the middle of the positioning groove. For example, the positioning block 230 can be symmetrically arranged based on a vertical plane passing through the axis of the first cavity 101, so that the center of gravity of the positioning block 230 is located on this vertical plane. Furthermore, the center of gravity of the positioning block 230 can be located in other positions depending on the shape of the outer surface of the housing 100.

[0042] The total weight of the positioning block 230 and the two counterweights 220 can be greater than the total weight of the movable counterweight 210. When the movable counterweight 210 flows within the first cavity 101, the housing 100 gradually tilts the portion with the positioning block 230 downwards during rolling. At this time, the opening of the positioning groove faces upwards, thus ensuring that the movable counterweight 210 can flow into the positioning groove. This avoids the problem of the movable counterweight 210 failing to accurately reset due to gravity balance with other structures outside the positioning groove. Of course, the positioning block 230 can also further reduce the center of gravity height of the speaker housing.

[0043] like Figure 3 and Figure 4 As shown, in some embodiments, the top height of the positioning block 230 is lower than the lowest point of the top surface of the counterweight block 220. This prevents the positioning block 230 from dividing the positioning groove into two independent parts, ensuring the overall connectivity of the positioning groove, allowing the movable counterweight 210 to flow completely into the positioning groove from one side, and preventing the positioning block 230 from affecting the reset of the movable counterweight 210.

[0044] In some embodiments, the housing 100 further has a second cavity 102 isolated from the first cavity 101, the second cavity 102 being used to mount the electronic module of the audio system.

[0045] The second cavity 102 is a hollow structure disposed within the housing 100. When the housing 100 is a columnar structure, the second cavity 102 and the first cavity 101 can be arranged along the axial direction of the housing 100. The shape of the second cavity 102 can also be arbitrary, adaptable to the electronic module of the audio system, providing an installation position for the electronic module, and embedding the electronic module inside the housing 100. The second cavity 102 and the first cavity 101 should be independently disposed to prevent the movable counterweight 210 from flowing into the second cavity 102 and affecting the operation of the electronic module.

[0046] When the electronic module is installed in the second cavity 102, the part of the housing 100 corresponding to the second cavity 102 should be provided with a hollow structure. The hollow structure can be composed of multiple small through holes to connect the second cavity 102 with the external environment and transmit the sound emitted by the electronic module to the outside.

[0047] Combination Figure 2 and Figure 5 As shown, in some embodiments, the housing 100 may include: a cylindrical body 110, a partition 120, and a cover plate 130; the cylindrical body 110 is a hollow cylinder; the partition 120 is disposed inside the cylindrical body 110, and the cover plate 130 is disposed in the cylindrical body 110 to close one of the openings of the cylindrical body 110; the surface of the partition 120 facing the cover plate 130, the inner surface of the cylindrical body 110, and the surface of the cover plate 130 facing the partition 120 together form a first cavity 101; the surface of the partition 120 facing away from the cover plate 130 and the inner surface of the cylindrical body 110 together form a second cavity 102.

[0048] Specifically, the cylinder 110 can be a hollow cylindrical structure with a circular cross-section, and both ends of the cylinder 110 are open. A circular partition 120 is built into the inside of the cylinder 110, and a cover plate 130 is placed over one of the open ends of the cylinder 110, sealing the opening. Under the action of the partition 120, the inner side of the cylinder 110 is divided into a first cavity 101 and a second cavity 102, and the cover plate 130 seals the end opening of the cylinder 110, making the first cavity 101 a closed environment to prevent the internal movable counterweight 210 from leaking out. The end of the cylinder 110 facing away from the cover plate 130 can be open to facilitate the installation of electronic modules into the second cavity 102. Alternatively, a removable cover plate 130 can be provided to protect the electronic modules and improve the overall aesthetics of the speaker.

[0049] In the eccentric structure 200, the counterweight 220 and the positioning block 230 can be fixed to corresponding positions on the inner surface of the cylinder 110 by means of bonding, welding, or fastener connection. The counterweight 220 and the positioning block 230 abut against the partition plate 120 and the cover plate 130 respectively at their two axial end faces, preventing gaps at the connection of the counterweight 220 from causing the movable counterweight 210 in the positioning groove to overflow. Furthermore, the cover plate 130 can be made of transparent material, making the movable counterweight 210 in the first cavity 101 visible. This improves the aesthetics of the speaker casing and allows for direct observation of the flow changes of the movable counterweight 210 within the first cavity 101 when the speaker casing shakes, enhancing its entertainment value.

[0050] In some embodiments, the cylinder 110 and the partition 120 are integrally formed to ensure that the first cavity 101 and the second cavity 102 are independent of each other, and to avoid the movable counterweight 210 from affecting the electronic module in the second cavity 102.

[0051] In some embodiments, the cover plate 130 is detachably connected to the cylinder 110. For example, the cover plate 130 can be connected to the end face of the cylinder 110 by means of plug-in connection, snap-fit ​​connection, threaded connection or screw connection, so as to facilitate the installation and maintenance of the eccentric structure 200, and also allow the user to replace the movable counterweight 210 in the first cavity 101 according to their own needs. In addition, a sealing structure such as a sealing ring can be provided between the end faces of the cover plate 130 and the cylinder 110 to ensure the sealing between the cover plate 130 and the cylinder 110 and prevent the movable counterweight 210 from overflowing from the connection between the cover plate 130 and the cylinder 110.

[0052] In some embodiments, there are two first cavities 101 symmetrically arranged on both sides of the second cavity 102, and each first cavity 101 is provided with an eccentric structure.

[0053] Specifically, such as Figure 6 As shown, two spaced-apart partitions 120 can be provided on the inner side of the cylindrical body 110, forming a second cavity 102 between the two partitions 120. Simultaneously, cover plates 130 are provided at both open ends of the cylindrical body 110, thus forming first cavities 101 on both sides of the second cavity 102. An eccentric structure is provided within each first cavity 101. One of the partitions 120 can be detachably connected to the inner wall of the cylindrical body 110, or the portion of the cylindrical body 110 located in the second cavity 102 can be made detachable to facilitate the installation of electronic modules into the second cavity 102. The eccentric structures on both sides ensure even force distribution on both sides of the housing 100, further reducing its center of gravity height. Of course, the number of second cavities 102 and eccentric structures can be increased depending on the structure of the housing 100.

[0054] Secondly, this application also provides an audio speaker, including an audio speaker housing as described in the first aspect embodiment and an electronic module mounted on the audio speaker housing.

[0055] Specifically, the electronic modules may include: an amplifier module, an audio processing module, a communication module, and a power supply module. The amplifier module amplifies the audio signal to ensure clear and distortion-free output sound quality; the audio processing module optimizes the input audio signal to improve sound quality; the communication module can be wired or wireless, such as Bluetooth or Wi-Fi, to facilitate user control and data transmission of the speakers; and the power supply module supplies and distributes power to each speaker to ensure stable operation of all modules.

[0056] The aforementioned modules can be integrated into a single electronic module, which is installed within the second cavity 102 of the housing 100. The electronic module is connected and fixed to the inner wall of the cylindrical body 110 using screws or other fasteners. The center of gravity of the electronic module can be close to the bottom surface of the housing 100 to balance the center of gravity positions of the eccentric structure 200 and the electronic module, improving the stability of the speaker during use. The portion of the cylindrical body 110 corresponding to the second cavity 102 can have multiple perforated structures to transmit the sound emitted by the electronic module to the outside.

[0057] The arc-shaped housing 100 also helps to enhance sound diffusion and reduce sound wave reflection, making the sound more natural and full. Thanks to the eccentric structure 200, the speaker can maintain a stable position without the need for supporting structures such as feet on the outside of the housing 100, facilitating the design and optimization of the speaker's shape. Furthermore, the movable counterweight 210 in the eccentric structure 200 can add a certain level of entertainment value to the speaker, improving the user experience.

[0058] 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.
