Description

Technical Field

[0001] This utility model relates to a speaker, and more particularly to a Bluetooth speaker with anti-tipping gravity sensing. Background Technology

[0002] A Bluetooth speaker is a portable audio device that uses Bluetooth technology for wireless audio transmission. It allows users to connect via Bluetooth and transmit audio content from a Bluetooth device (such as a smartphone, tablet, or computer) to the Bluetooth speaker for playback. These speakers typically have a built-in rechargeable battery, enabling mobile use in various settings without relying on a power outlet.

[0003] With the development of wireless audio technology and consumers' pursuit of convenience, Bluetooth speakers have become an indispensable part of people's daily lives. Whether at home, in the office, or during outdoor activities, Bluetooth speakers have won widespread market recognition for their portability and ease of use. However, despite the continuous advancements in Bluetooth speaker design, they still have shortcomings in some aspects, especially in terms of stability and durability. Most existing Bluetooth speakers typically use a simple bottom support structure. While this design can meet basic usage needs, it is prone to tipping over on uneven surfaces or when subjected to minor impacts. Once a speaker tipps over, it not only affects the sound quality experience but may also cause damage to the device, especially for speakers without built-in drop protection. Furthermore, in certain situations, such as outdoor parties or when there are children or pets at home, speakers are more likely to tip over due to accidental collisions, increasing the risk of device damage.

[0004] Therefore, it is necessary to design a Bluetooth speaker with anti-tipping gravity sensing to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings mentioned in the background art, the present invention provides a Bluetooth speaker with anti-tipping gravity sensing.

[0006] The technical solution is as follows: A Bluetooth speaker with anti-tipping gravity sensing includes a speaker, a sleeve, a wedge block, a lever 1, a spring 1, a slide rod, a weight-adding block, a cylinder 1, a support rod, a fixing block, a spring 2, a lever 2, a ball bearing, and a spring 3. Two storage slots 1 are symmetrically opened on both sides of the speaker. A sleeve is rotatably connected to the top of each storage slot 1. Storage slots 2 are opened on both sides of each sleeve. A lever 1 is slidably connected to the inner wall of each storage slot 2. A wedge block is fixed to one end of each lever 1. Each wedge block is located in a storage slot 2. Two wedge blocks on the same side are opposite and symmetrically distributed. A spring 1 is fixed between each wedge block on the same side and the lever 1. A ball bearing is slidably connected to the middle of each sleeve. There are sliding rods, each with symmetrical cavities on both sides, the cavities being the same size as the wedge blocks. A weight block is fixed to the bottom of each sliding rod. A cylinder is symmetrically slidably connected to one side of the speaker box. Each cylinder has a circular hole on its side. A support rod is slidably connected inside each cylinder. A fixing block is fixed to the middle of each support rod, located inside the cylinder. A spring is fixed between the inner wall of each cylinder and the fixing block on the same side. Pull rods are slidably connected to both sides of the speaker box. One end of the pull rod is inserted into the speaker box and fixed with a ball bearing. A spring is fixed between the pull rod and the ball bearing on the same side. Both the ball bearing and the spring are located inside the speaker box. The diameter of the ball bearing is slightly smaller than the diameter of the circular hole on the side of the cylinder.

[0007] As a further preferred option, it also includes a tilt sensor and a wiring conduit. The tilt sensor is fixedly connected inside the speaker, and a wiring conduit is fixedly connected to one side of the tilt sensor. The connector of the wiring conduit extends out from one side of the speaker.

[0008] As a further preferred option, it also includes protective covers and magnets. The top of the speaker is symmetrically and slidingly connected with protective covers. Magnets are fixed to the sides of the two protective covers that are close to each other, and each magnet is embedded in the side of the protective cover on the same side.

[0009] As a further preferred option, it also includes a telescopic rod and a handle. The telescopic rod is slidably connected to one side of the speaker, is embedded inside the speaker, and has a handle fixed to the top of the telescopic rod.

[0010] As a further preferred embodiment, it also includes a second cylinder, a fixed rod, bolts, nuts, and pulleys. The second cylinder is fixedly connected to one side of the speaker. The fixed rod is slidably connected inside the second cylinder. The inner diameter of the second cylinder is larger than the outer diameter of the fixed rod, meaning that the inner wall of the second cylinder does not contact the outer wall of the fixed rod, and sufficient space is reserved between them. Bolts are threadedly connected to the side wall of the second cylinder. One end of the bolt passes through the inner wall of the second cylinder and contacts the outer wall of the fixed rod. Two pulleys are symmetrically fixed to one end of the fixed rod. In the initial state, the pulleys do not contact the ground.

[0011] As a further preferred option, the bottom of the speaker is fixed with an anti-slip rubber pad.

[0012] The present invention has the following advantages: 1. The present invention uses the sliding rod to slide out to the limit state along the tilting angle under the action of its own inertia and the action of the weight block. The wedge block extends into the cavity of the sliding rod under the action of the spring, and locks the sliding rod, so that the bottom of the weight block contacts the ground and supports the speaker, thereby preventing the speaker from falling directly to the ground and protecting the speaker.

[0013] 2. In this utility model, both the cylinder and the support rod slide out to their limit positions along the tilting angle, so that the sliding ball extends into the round hole on one side wall of the cylinder under the action of the spring three, locking the cylinder one. At the same time, under the buffering action of the spring two, neither the cylinder one nor the support rod will shake significantly. Thus, the two work together to effectively provide auxiliary support for the speaker. Attached Figure Description

Detailed Implementation

[0025] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0026] Example: A Bluetooth speaker with anti-tipping gravity sensing, such as... Figures 1-4 , Figure 7 and Figure 8As shown, the device includes a speaker 1, a sleeve 3, a wedge block 5, a pull rod 1 6, a spring 1 7, a slide rod 8, a weight block 9, a cylinder 10, a support rod 11, a fixing block 12, a spring 2 13, a pull rod 2 14, a ball bearing 15, and a spring 3 16. The bottom of the speaker 1 is fixed with an anti-slip pad using adhesive to increase friction and prevent the speaker from sliding on smooth surfaces such as glass or marble, ensuring its stability. The speaker 1 has two symmetrical storage slots 1 2 on both the front and back sides. Each of the four storage slots 1 2 has a sleeve 3 rotatably connected to its top. Each of the four sleeves 3 has a storage slot 2 on its left and right sides. 4. Each of the eight storage slots 24 has a sliding lever 6 connected to its inner wall. Each of the eight levers 6 has a wedge-shaped block 5 welded to one end of each lever. All eight wedge-shaped blocks 5 are located inside the storage slots 24. Two wedge-shaped blocks 5 on the same side are opposite and symmetrically distributed. The left wedge-shaped block 5 tilts downwards from left to right, and the right wedge-shaped block 5 tilts downwards from right to left, achieving a two-way locking function. A spring 7 is welded between each wedge-shaped block 5 on the same side and the lever 6. The four sleeves 3 have a hollow structure in the middle, and each of the four sleeves 3 has a sliding rod 8 connected to its middle. The four sliding rods 8 have symmetrical cavities on both sides. The cavity is the same size as the wedge block 5. Initially, the wedge block 5 is not located inside the cavity. The wedge block only enters the cavity when needed, which can reduce unnecessary friction and wear, and reduce noise that may be caused by loose parts. The bottom of each of the four sliding rods 8 is connected to a weight block 9 by screws. The rear side of the speaker box 1 is symmetrically connected to two cylinders 10. Both cylinders 10 have round holes on their sides. Support rods 11 are slidably connected inside the two cylinders 10. Fixing blocks 12 are welded to the middle of the two support rods 11. The fixing blocks 12 are located inside the cylinders 10. Spring 13 is welded between the inner wall of cylinder 10 and the fixing block 12 on the same side. Pull rod 14 is slidably connected to both sides of the speaker box 1. The ends of the two pull rods 14 that are close to each other are brazed into the speaker box 1 and have ball bearings 15. Using ball bearings 15 as an intermediary can distribute pressure and reduce wear caused by friction. Spring 3 16 is welded between the pull rod 14 and ball bearings 15 on the same side. Both ball bearings 15 and spring 3 16 are located inside the speaker box 1. The diameter of ball bearing 15 is slightly smaller than the diameter of the circular hole on the side of cylinder 10, so that ball bearing 15 can be easily inserted into the circular hole on the side of cylinder 10.

[0027] like Figure 1 , Figures 5-6 and Figure 9As shown, it also includes a tilt sensor 17, a wiring conduit 18, a protective cover 19, a magnet 20, a telescopic rod 21, and a handle 22. The tilt sensor 17 is installed on the inner side of the bottom of the speaker 1 by screws. The wiring conduit 18 is fixed to the rear side of the tilt sensor 17 by clamps. The connector of the wiring conduit 18 extends out of the rear side of the speaker 1. The protective covers 19 are symmetrically slidably connected to the top of the speaker 1. The magnets 20 are fixed to the sides of the two protective covers 19 that are close to each other by adhesive, and the two magnets 20 are embedded in the inner side of the protective cover 19 on the same side. The telescopic rod 21 is slidably connected to the rear side of the speaker 1. The telescopic rod 21 is embedded inside the speaker 1. The handle 22 is connected to the top of the telescopic rod 21 by screws.

[0028] like Figure 5 and Figure 10 As shown, it also includes a second cylinder 23, a fixing rod 24, a bolt 25, a nut 26, and a pulley 27. The second cylinder 23 is connected to the rear side of the speaker 1 by screws. The fixing rod 24 is slidably connected inside the second cylinder 23. The inner diameter of the second cylinder 23 is larger than the outer diameter of the fixing rod 24, that is, the inner wall of the second cylinder 23 does not contact the outer wall of the fixing rod 24, and sufficient space is reserved between them. The bolt 25 is threadedly connected to the side wall of the second cylinder 23. One end of the bolt 25 passes through the inner wall of the second cylinder 23 and contacts the outer wall of the fixing rod 24. The lower end of the fixing rod 24 is symmetrically connected to the left and right sides by screws to the pulleys 27. In the initial state, the pulleys 27 do not contact the ground.

[0029] When speaker 1 is needed, the user simply needs to place it vertically in the designated area. To connect the electronic device to speaker 1, first pull open the protective covers 19 on both sides of speaker 1 so that the magnets 20 on the inner wall are disengaged. Then pull the two protective covers 19 to their maximum positions to ensure that the control knob is not obstructed. Then turn on the power to the control knob and wait for speaker 1 to start up and enter working mode. Then turn on the electronic device and connect it to speaker 1. At this time, the user can freely switch music modes. In addition, the user can also directly insert the music hard drive and play or switch tracks through the control knob.

[0030] When speaker 1 is not placed horizontally or is subjected to external force, it may tip over. In this case, tilt sensor 17 reads tilt data (angle or acceleration value) in real time and calculates the actual tilt angle using a DMP (Digital Motion Processor) to determine if a set threshold has been reached. If the set threshold is exceeded, tilt sensor 17 directly outputs an analog voltage signal, transmitting the information to the control knob module. The module then controls speaker 1 to play a specified audio file, while LEDs flash intermittently to alert the user that speaker 1 may tip over and that the user should adjust its position to ensure it is in a safe state. When speaker 1 tilts forward, the two front sides... Under the influence of its own inertia and the weight block 9, the sliding rod 8 slides forward along the tilting angle. When the sliding rod 8 reaches its limit, the wedge block 5 is no longer squeezed by the left and right side walls of the sliding rod 8 and, under the action of the spring 7, extends into the cavity of the sliding rod 8, locking the sliding rod 8. At this time, the bottom of the weight block 9 contacts the ground and supports the speaker 1, preventing the speaker 1 from falling directly to the ground and effectively protecting the speaker 1. Similarly, when the speaker 1 tilts backward, the sliding rod 8, weight block 9, and wedge block 5 on the rear side work together to support the speaker 1. At the same time, when the speaker 1 tilts backward, the cylinder 10 and the support rod 11 both slide backward along the tilting angle. When the cylinder 10 moves to its limit position, the circular hole on the side of the cylinder 10 and the sliding rod 11... When bead 15 is aligned, the sliding bead 15 extends into the round hole under the action of spring 3 16, locking cylinder 10. When support rod 11 contacts the ground, it receives the reaction force from the ground, resulting in partial reset, i.e., support rod 11 retracts. At this time, under the buffering action of spring 2 13, neither cylinder 10 nor support rod 11 will wobble significantly, thus cooperating to support speaker 1. When the user straightens speaker 1 and needs to reset sliding rod 8, the user pulls lever 1 6 outwards. At this time, the two wedge blocks 5 on the same side move towards each other and disengage from the cavity of sliding rod 8. Then the user manually pushes sliding rod 8 upwards, causing it to extend into sleeve 3. When sliding rod 8 moves upwards to its limit... When in position, the user releases lever 6. At this time, the two wedge blocks 5 on the same side are reset by spring 7 and apply pressure to the side wall of slide rod 8 to fix slide rod 8, thus realizing the retraction and reset of slide rod 8. Similarly, the user pulls lever 14 outward to move ball 15 outward until it is disengaged from the round hole on the side wall of cylinder 10. At this time, cylinder 10 is not fixed. The user pushes support rod 11 forward to retract and reset support rod 11 into cylinder 10. At the same time, cylinder 10 retracts and resets into speaker 1. Then the user releases lever 14, and ball 15 is reset by spring 16 and applies pressure to the side wall of cylinder 10 to limit and fix cylinder 10, thus realizing the reset of all support components.

[0031] When speaker 1 is not in use, the user pushes the two protective covers 19 inwards until their inner walls contact each other. At this point, the two magnets 20 attract each other, fixing the two protective covers 19 in place and preventing dust from adhering to the control knob when speaker 1 is not in use, effectively protecting the components on the control knob. When speaker 1 needs to be moved a distance, the user rotates nut 26 counterclockwise and unscrews bolt 25 outwards, disengaging bolt 25 from the side wall of fixing rod 24. Fixing rod 24 then moves downwards under its own weight until pulley 27 contacts the ground. The user then tightens bolt 25 to reset it, and then rotates nut 26 clockwise. The nut 26 limits and fixes the bolt 25. At this time, the bolt 25 applies a compressive force to the side wall of the fixing rod 24, thus limiting and fixing the fixing rod 24. Then, the user pulls the telescopic rod 21 upward through the handle 22 to fully extend the telescopic rod 21. Subsequently, the user can directly pull the speaker 1 through the handle 22. At the same time, the pulley 27 effectively achieves a labor-saving effect. Similarly, first, the fixing rod 24 is disengaged from the bolt 25, and the fixing rod 24 is pulled upward to disengage the pulley 27 from the ground. Then, the bolt 25 is fixed by the nut 26 to reset the pulley 27. The telescopic rod 21 can be reset by pushing the handle 22 downward.

[0032] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
