Description

Technical Field

[0001] This utility model relates to the field of speaker reinforcement structure technology, and in particular to a speaker enclosure reinforcement structure that is drop-proof and impact-resistant. Background Technology

[0002] A speaker is a device that converts audio signals into sound. It consists of a vibration system and a cabinet that supports, fixes, and optimizes acoustic performance. It is widely used in home theaters, music playback, conference systems, public address systems, and other fields, and is an indispensable and important component of audio systems.

[0003] A search revealed that Chinese patent number CN205883479U discloses a speaker with a drop-proof structure, including a speaker body and a drop-proof protective structure fixed to the outside of the speaker body. The drop-proof protective structure includes a drop-proof frame formed by several rigid rods bending outward. The drop-proof frame has a bent rod in the middle and two free rods formed by bending perpendicularly to the bent rod. A flexible silicone material is used to connect the drop-proof frame and the speaker body, which can play a good cushioning role and avoid vibration damage to the internal structure of the speaker.

[0004] A search revealed that Chinese patent number CN218336309U discloses a trolley speaker for live streaming, comprising a speaker body, a trolley rod installed on the rear side of the speaker body, and universal wheels with self-locking function installed at the four corners of the bottom of the speaker body. A lifting rod is rotatably connected to the top of the speaker body, and a fill light is connected to the lifting rod. Both ends of the lifting rod are connected to connecting rods, which facilitates fixing the mobile phone for live streaming during the use of the trolley speaker. At the same time, the fill light and mobile phone holder can be easily folded and stored on the top of the trolley speaker to reduce the space occupied when placed.

[0005] However, during the implementation of the above technical solution, at least the following technical problems were discovered:

[0006] Large size and unstable: The bumper increases the overall size of the speaker, requiring extra space for carrying, especially in outdoor performances and mobile offices, increasing the difficulty and cost of handling and transportation (as disclosed in the above-mentioned patent CN205883479U). When not in use, the protruding bumper is difficult to store compactly, taking up home or storage space and affecting the cleanliness of the environment. When used in narrow spaces, the large bumper may cause placement difficulties and even affect the layout of other equipment. The support area of ​​the rollers is small due to their point contact (as disclosed in the above-mentioned patent CN218336309U), and the speaker is prone to shaking, tilting or even tipping over due to external forces, especially on uneven ground or during movement. The rollers have limited friction with the ground, and on smooth ground or in inclined environments, the speaker may slide spontaneously, causing positional displacement or equipment damage. Utility Model Content

[0007] The purpose of this utility model is to provide a speaker enclosure reinforcement structure that is drop-proof and impact-resistant. This structure solves the problems of increased speaker size due to the impact bracket, which requires extra space for carrying, especially in outdoor performances and mobile offices, increasing the difficulty and cost of handling and transportation. When not in use, the protruding impact bracket is difficult to store compactly, taking up home or storage space and affecting the cleanliness of the environment. When used in narrow spaces, a large impact bracket may cause placement difficulties and even affect the layout of other equipment. The small point contact support area of ​​the rollers makes the speaker prone to shaking, tilting, or even tipping over due to external forces, especially on uneven ground or during movement. The limited friction between the rollers and the ground means that the speaker may slide spontaneously on smooth ground or in inclined environments, leading to displacement or equipment damage.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a speaker enclosure reinforcement structure for drop and impact resistance, comprising a speaker body, and further comprising: anti-collision frames disposed on the outside of the speaker body for absorbing impacts received by the speaker body; limiting members disposed on the outside of both ends of the speaker body for adjusting the distance between the two anti-collision frames; a base plate disposed on the outside of the bottom end of the speaker body for increasing the contact area between the speaker body and the ground; and a support member disposed on one side of the speaker body.

[0009] In a preferred embodiment, the limiting member includes: a mounting frame disposed on the outer sides of both ends of the speaker body, a gear disposed on the inner side of the mounting frame, a toothed plate disposed on the inner side of the mounting frame, one side of the toothed plate contacting the outer side of the gear, a connecting rod disposed on the outer side of the toothed plate, and one side of the connecting rod connected to one side of the anti-collision frame.

[0010] In a preferred embodiment, the anti-collision frame has a U-shaped structure, surrounds the rear side of the speaker body, and has a rubber ring on its outer side.

[0011] In a preferred embodiment, a motor is provided on the upper surface of the mounting frame, and the motor passes through the outer end of the mounting frame and is connected to one side of the gear.

[0012] In a preferred embodiment, a handle is provided on one side of the mounting frame, a handle cover is provided on the outside of the handle, the handle cover is made of sponge material, and casters are provided on the lower surface of the mounting frame.

[0013] In a preferred embodiment, the support includes: a connecting cylinder disposed on one side of the base plate, a support arm disposed on the outer side of one end of the mounting frame, and a threaded rod disposed on the inner side of the end of the support arm, wherein the threaded rod is connected to the inner side of the connecting cylinder.

[0014] In a preferred embodiment, a rotating handle is provided on the outer side of the end of the threaded rod, and a limiting plate is provided on one side of the base plate.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In use, by controlling the start, stop and direction of the motor, the distance between the two anti-collision frames can be precisely adjusted. When facing strong impact scenarios, the distance between the anti-collision frames is increased to expand the protection range. After the anti-collision frames unfold outward, they form a surrounding protective boundary. The impact force is absorbed through structural deformation, reducing the direct force on the speaker body. During daily use or storage, the motor is started to reverse, reducing the distance between the anti-collision frames to the minimum, reducing space occupation. The motor drives the gear to rotate, and through the meshing transmission of the gear and the toothed plate, the operation is convenient and efficient. It drives the base plate to contact the ground and lifts the speaker body, increasing the support area by replacing point contact with surface contact. Combined with the self-locking characteristics of the thread, it effectively improves stability and prevents tipping. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 1 , Figure 3 and Figure 5 This utility model provides a technical solution: a speaker enclosure reinforcement structure for drop and impact resistance, including a speaker body 1, an anti-collision frame 204 and a limiting member, wherein the limiting anti-collision frame 204 is movably connected to the outside of the speaker body 1 through the limiting member;

[0027] In this embodiment, the specific type of the limiting member can be various, and this application does not limit it. As an example of adjusting the spacing of the anti-collision frame 204, in an optional solution, such as... Figure 5 As shown, the multiple linkage components include: a mounting frame 2 fixedly connected to both ends of the speaker body 1, the inside of which is a hollow mechanism; a gear 201 is rotatably connected to the inner side of the mounting frame 2; the gear 201 is used to drive the toothed plate 202 slidably connected to the inner side of the mounting frame 2 to move synchronously; a toothed structure is provided on one side of the toothed plate 202; the gear 201 is meshed with the toothed structure on one side of the toothed plate 202; a connecting rod 203 is fixedly connected to the outer side of one end of the toothed plate 202; the connecting rod 203 is used to connect to the anti-collision frame 204 and fix the anti-collision frame 204.

[0028] The U-shaped structure of the anti-collision frame 204 extends from the outside of the speaker body 1 to the rear of the speaker body 1, providing multi-directional protection for the outer surface of the speaker body 1. Meanwhile, a handle 207 is fixedly connected to one side of the mounting frame 2. The handle 207 extends outward. When the speaker body 1 tilts forward, the handle 207 contacts the ground first. When the speaker body 1 tilts to the sides and rear, the anti-collision frame 204 contacts the ground first.

[0029] It should be noted that the handle sleeve 208, which is fitted onto the outside of the handle 207, can be used to absorb the potential energy generated during an impact, and can also be used to increase the friction between the hand and the device when it is pulled.

[0030] In practical implementation, when the user needs to protect the speaker body 1 with the anti-collision frame 204, the user can start the motor 206. The motor 206 drives the gear 201 to rotate. As the gear 201 rotates, it will drive the two gear plates 202 to move outward through its meshing connection with the gear plate 202. At the same time, it will drive the two anti-collision frames 204 to move outward. The user can control the distance between the two anti-collision frames 204 according to the required level of protection. When no protection is needed, the user can start the motor 206 to reverse and move the distance between the two anti-collision frames 204 to the minimum. At this time, the device is compact and easy to carry.

[0031] Example 2

[0032] It should be noted that, based on the speaker body 1 in the embodiment, this application provides a technical solution to increase the contact area between the bottom of the device and the ground, such as... Figure 4 and Figure 6 As shown, the overall approach is as follows:

[0033] The support components include:

[0034] A connecting cylinder 301 is fixedly connected to the outer side of the end of the base plate 3. The connecting cylinder 301 is used to support the base plate 3. A support arm 302 is fixedly connected to the upper surface of the top mounting frame 2. A threaded rod 303 is rotatably connected to the inner side of the support arm 302. The outer side of the threaded rod 303 is threadedly connected to the inner side of the connecting cylinder 301 to adjust the distance between the threaded rod 303 and the connecting cylinder 301. At the same time, a rotating handle 304 is fixedly connected to the outer side of the end of the threaded rod 303 for rotating the threaded rod 303.

[0035] The limiting plate 305, which is fixedly connected to the upper surface of the base plate 3, can be inserted into the bottom inner side of the speaker body 1 to provide further support for the base plate 3.

[0036] In the specific implementation process, when the user needs to move the speaker body 1, he can pull the device to move it via the casters 209. When the speaker body 1 needs to stand stably, the user can rotate the two rotating handles 304, which in turn drives the two threaded rods 303 to rotate. Due to the threaded connection between the threaded rods 303 and the connecting cylinder 301, when the threaded rods 303 rotate, they will push the connecting cylinder 301 away from the threaded rods 303. This will drive the base plate 3 to move towards the ground until the base plate 3 contacts the ground and lifts the speaker body 1. At this time, the surface contact between the base plate 3 and the ground replaces the point contact between the casters 209 and the ground, increasing the contact area and thus increasing the stability of the speaker body 1 and preventing it from tipping over.

[0037] Working principle:

[0038] Based on Example 1, the distance between the two anti-collision frames 204 is precisely adjusted by controlling the start, stop and direction of the motor 206. When facing a strong impact scenario, the distance between the anti-collision frames 204 is increased to expand the protection range. After the anti-collision frames 204 expand outward, they form a surrounding protective boundary. The impact force is absorbed through structural deformation, reducing the direct force on the speaker body 1. During daily use or storage, the motor 206 is started to reverse, reducing the distance between the anti-collision frames 204 to the minimum, reducing space occupation. The motor 206 drives the gear 201 to rotate, and the operation is convenient and efficient through the meshing transmission between the gear 201 and the toothed plate 202.

[0039] Based on Example 2, convenient movement is achieved through casters 209. When stable standing is required, the user only needs to rotate the handle 304 to drive the threaded rod 303. Utilizing the threaded transmission between the handle and the connecting cylinder 301, the base plate 3 is driven to contact the ground and lift the speaker body 1. The surface contact is replaced with point contact to increase the support area. Combined with the self-locking characteristics of the thread, stability is effectively improved and tipping is prevented. When not in use, the base plate 3 can be retracted and hidden. The structure is compact and does not take up much space. The threaded transmission design is durable and labor-saving, taking into account both mobility and standing reliability. It is suitable for speaker usage needs in multiple scenarios. At the same time, the two connecting cylinders 301 can also absorb the impact when the speaker body 1 is tilted forward.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
