Description

Technical Field

[0001] This utility model relates to the field of Bluetooth speaker technology, specifically a Bluetooth speaker with a drop-proof structure. Background Technology

[0002] A Bluetooth speaker is a portable audio device that uses Bluetooth technology to transmit audio wirelessly. It frees users from the constraints of traditional wired connections, allowing them to easily pair with Bluetooth-enabled devices such as smartphones, tablets, and laptops to play music or other audio content. Bluetooth speakers typically have a built-in battery, enabling use outdoors or in locations far from a power source, and come in a variety of designs.

[0003] However, existing Bluetooth speakers generally lack a protective casing design. During use, users may accidentally touch the speaker, causing it to fall from a height. Without effective protection, the impact of the speaker landing may cause cracks in the exterior and damage to internal components, thus affecting its performance and shortening its lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a Bluetooth speaker with a drop-proof structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A Bluetooth speaker with a drop-proof structure includes an arc-shaped base plate and a speaker body. A counterweight is provided at the center of the upper surface of the arc-shaped base plate. A movable sleeve is symmetrically provided on both sides of the counterweight. A fixed rod is symmetrically provided at the bottom of the speaker body. The bottoms of two fixed rods are respectively inserted into the corresponding movable sleeves to form telescopic rods. A return spring is sleeved on the telescopic rod. One end of the return spring abuts against the bottom of the speaker body, and the other end abuts against the upper surface of the arc-shaped base plate. Several outwardly inclined support legs are symmetrically arranged around the bottom of the arc-shaped base plate. The lowest point of each support leg is higher than the lowest point of the arc-shaped base plate.

[0007] Furthermore, each of the aforementioned support legs includes a fixed rod II, a movable sleeve II, and a return spring II. The bottom of the fixed rod II is inserted into the movable sleeve II, and the return spring II is disposed outside the fixed rod II. One end of the return spring II abuts against the bottom of the arc-shaped base plate, and the other end abuts against the top of the movable sleeve II. The bottom of the movable sleeve II is provided with a spherical pad.

[0008] Furthermore, end caps are symmetrically installed on both sides of the speaker body, and each end cap is provided with a handle, and the two handles are fixedly connected with nylon ropes.

[0009] Furthermore, a plurality of rubber pillars are integrally formed on the outer side walls of the two end caps, and the height of the rubber pillars is higher than that of the handle.

[0010] Furthermore, the rubber columns on both sides are inclined outwards.

[0011] The beneficial effects of this utility model are:

[0012] This invention features a counterweight at the center of the upper surface of an arc-shaped base plate. This counterweight ensures that the center of gravity of the arc-shaped base plate remains in the middle, achieving a roly-poly effect. When the speaker is accidentally touched, it automatically returns to its original shape, preventing it from tipping over and eliminating the need for manual adjustment by the user, thus increasing the fun.

[0013] The speaker body features symmetrical movable sleeves on both sides of the counterweight and symmetrical fixed rods at the bottom. The bottoms of the two fixed rods are inserted into the corresponding movable sleeves, forming telescopic rods. Each telescopic rod is fitted with a return spring. One end of the return spring abuts against the bottom of the speaker body, and the other end abuts against the upper surface of the curved base plate. When the speaker body, placed on a table, falls due to an accidental collision, it will typically tilt slightly. Because the counterweight is positioned at the center of the curved base plate, the center of gravity of the entire curved base plate remains stable and centered. After the external force causing the tilt is removed, the speaker body automatically returns to its original position, reducing the tilt angle during the fall and ensuring the curved base plate falls vertically directly below the speaker body. When the speaker body lands, the curved base plate contacts the ground first. At this point, the speaker body drives the fixed rods to move downwards along the movable sleeves and compresses the return spring, thus providing a cushioning effect. This effectively reduces the impact force during the fall, minimizing damage to internal components and extending the lifespan of the speaker body.

[0014] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please refer to Figure 1-3 ;

[0021] A Bluetooth speaker with a drop-proof structure includes an arc-shaped base plate 1 and a speaker body 2. The arc-shaped base plate 1 is located below the speaker body 2 and is used to contact the ground or tabletop. A counterweight 11 is provided at the center of the upper surface of the arc-shaped base plate 1. The counterweight 11 ensures that the center of gravity of the arc-shaped base plate 1 is always in the middle, thus achieving a roly-poly effect. When the speaker body 2 is accidentally touched, it can automatically return to its original shape, making it less likely to tip over and eliminating the need for manual uprighting by the user, thus increasing the fun. Symmetrical movable sleeves 12 are provided on both sides of the counterweight 11, and symmetrical fixed rods 21 are provided on the bottom of the speaker body 2. The bottoms of the two fixed rods 21 are respectively inserted into the corresponding movable sleeves 12 to form telescopic rods. A return spring 22 is sleeved on the telescopic rod. One end of the return spring 22 abuts against the bottom of the speaker body 2, and the other end abuts against the upper surface of the arc-shaped base plate 1. When the speaker unit 2, placed on a table, is accidentally dropped, it will typically tilt slightly. Because the counterweight 11 is positioned at the center of the curved base plate 1, the center of gravity of the entire curved base plate 1 remains stable and centered. After the external force causing the tilt is removed, it automatically returns to its original position, reducing the tilt angle during the fall and ensuring that the curved base plate 1 falls vertically directly below the speaker unit 2. When the speaker unit 2 lands, the curved base plate 1 contacts the ground first. At this point, the speaker unit 2 drives the fixing rod 21 to move downwards along the movable sleeve 12, compressing the return spring 22, thus providing a cushioning effect. This effectively reduces the impact force during the fall and prevents damage to internal components, extending the service life of the speaker unit 2. In addition, several outwardly inclined support legs 3 are symmetrically arranged around the bottom perimeter of the curved base plate 1. The support legs 3 can limit the swing amplitude of the curved base plate 1, prevent it from being pushed over by external forces, and improve the stability of the speaker body 2 during use. The lowest point of each support leg 3 is higher than the lowest point of the curved base plate 1, avoiding direct contact between the support legs 3 and the ground or tabletop, which would prevent the curved base plate 1 from tilting forward or backward and reduce the fun of using the speaker body 2. In order to prevent the curved base plate 1 from directly hitting the ground and damaging the floor when the speaker body 2 falls vertically, a rubber pad is added to the bottom of the curved base plate 1 to cushion the impact force when the curved base plate 1 hits the floor.

[0022] To prevent the speaker body 2 from tilting too far forward or backward upon impact, which would prevent the counterweight 11 from fully correcting the tilt and causing the speaker body 2 to remain tilted too far upon landing, thus preventing the return spring 22 from triggering properly and indirectly causing the speaker body 2 to collide hard with the ground and be damaged, several support legs 3 include a fixed rod 31, a movable sleeve 32, and a return spring 33. The bottom of the fixed rod 31 is inserted into the movable sleeve 32, and the return spring 33 is located outside the fixed rod 31. One end of the return spring 33 abuts against the bottom of the curved base plate 1, and the other end abuts against the top of the movable sleeve 32. The bottom of the movable sleeve 32 is provided with a spherical pad 34, which is used to better adapt to slightly uneven ground. When the speaker body 2 tilts forward or backward at a large angle and falls from a height, the spherical pad 34 on the corresponding side will touch the ground first before the arc-shaped base plate 1 touches the ground. After the spherical pad 34 touches the ground, it will drive the movable sleeve 32 to move upward along the direction of the fixed rod 31, compressing the reset spring 33, thereby buffering the arc-shaped base plate 1 and indirectly protecting the speaker body 2 from impact damage.

[0023] In this embodiment, end caps 4 are symmetrically installed on both sides of the speaker body 2. Each end cap 4 is provided with a handle 41, and the two handles 41 are fixedly connected with nylon ropes 42 for easy carrying by the user.

[0024] In this embodiment, several rubber pillars 43 are integrally formed on the outer side walls of the two end caps 4 at equal intervals, and the height of the rubber pillars 43 is higher than that of the handle 41. When the speaker body 2 is subjected to a large impact, causing the front end, rear end, or top end of the speaker body 2 to fall directly towards the base plate, these rubber pillars 43 will first contact the ground, absorbing part of the impact force and playing an auxiliary buffering role, preventing the speaker body 2 from directly colliding with the ground. In addition, the rubber pillars 43 on both sides are inclined outwards. The rubber pillars 43 on both sides will absorb impact energy through bending and compression, reducing rigid collisions, and at the same time, decomposing the impact force, thereby enhancing the protection effect on the speaker body 2. Alternatively, the rubber pillars 43 can also be inclined towards the center of the speaker body 2, with the same effect as the outward inclination, and this is not a limitation.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
