Description

Technical Field

[0001] The present invention relates to the technical field of speakers, and in particular to a mobile combined digital media audio Background Art

[0002] With the rapid development of digital media technology, the demand for audio equipment in various occasions is increasing day by day. Whether it is indoor home entertainment, commercial activities, or outdoor performances, parties, etc., high-quality audio equipment is required to provide excellent sound effects. The mobile combined digital media audio is designed to meet these diverse application scenarios. For example, in a home theater, users hope that the audio can provide an immersive sound experience; in commercial activities, the audio needs to be portable and flexible to adapt to the needs of different venues; in outdoor performances, the audio needs to have powerful power and stable performance.

[0003] Many traditional audio equipment can provide good sound effects during use, but there are inconveniences in storage and transportation. Some large audio equipment is bulky and difficult to move and store, which limits its application in different occasions. While some small audio equipment is portable, but its sound effects and functions cannot meet the needs of users.

[0004] Therefore, there is a lack of a mobile combined digital media audio to solve the contradiction between use and storage, and provide users with an audio solution that not only has powerful sound effects but also is convenient for storage and transportation. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a mobile combined digital media audio, which solves the problems raised in the above background art.

[0006] Technical solution: To solve the above technical problems, according to one aspect of the present invention, more specifically, it is a mobile combined digital media audio, including a chassis. On the upper surface of the chassis, two vertical frames are fixed. On the rear surface of the vertical frame located at the rear, a rear frame is fixed. On the top of the rear frame, a top cover is fixed. An inner groove is opened inside the top cover. On the upper surface of the inner part of the chassis, a motor is fixed. The top end of the output shaft of the motor penetrates to the upper surface of the chassis and is fixed with a first screw rod. A lifting frame is threadedly connected to the outer surface of the first screw rod. The lifting frame is located between the two vertical frames. Above the front surface of the lifting frame, a first audio group is embedded. On the front surface of the vertical frame located in the front, a second audio group is embedded. On the upper surface of the chassis, two rotating rods are rotatably connected. At the top of the rotating rod, a first straight gear is fixed inside the inner groove. A second straight gear is meshed with the outer surface of the first straight gear. A third straight gear is meshed with the outer surface of the second straight gear. A worm gear is fixed in the middle of the third straight gear. The outer surfaces of the two worm gears are jointly meshed with a worm. A rotating frame is fixed on the outer surface of the worm. A cover plate is fixed at the front end of the rotating frame. A protective frame is fixed on the outer surface of the rotating rod. A third audio group is embedded on the inner side wall of the protective frame.

[0007] Furthermore, the bottom end of the rotating rod located on the left penetrates to the inside of the chassis and is fixed with a transmission gear. On the upper surface of the inner part of the chassis, a toothed ring is rotatably connected. Four second through grooves and four first through grooves are opened on the outer surface of the chassis. A second rotating shaft is rotatably connected inside the first through groove. A leg is fixed on the outer surface of the second rotating shaft. Above the first through groove, a bracket is fixed. The bottom end of the bracket is rotatably connected with a first rotating shaft. At one end of the first rotating shaft located inside the leg, a first bevel gear is fixed. At one end of the first rotating shaft located inside the chassis, a fourth straight gear is fixed. On the outer surface of the second rotating shaft located inside the leg, a second bevel gear is fixed. The second bevel gear is meshed with the first bevel gear.

[0008] Furthermore, a fifth straight gear is rotatably connected to the lower surface inside the second through groove. A second screw rod is fixed in the middle of the fifth straight gear. A screw plate is threadedly connected to the outer surface of the second screw rod. On the outer surface of the screw plate located outside the chassis, a lifting plate is fixed. A universal wheel is fixed on the lower surface of the lifting plate.

[0009] Furthermore, a number of first tooth grooves are opened on the inner surface of the toothed ring, a number of second tooth grooves are opened on the lower surface of the toothed ring, and a number of third tooth grooves are opened on the outer surface of the toothed ring. The toothed ring is meshed with the transmission gear through the first tooth groove, the toothed ring is meshed with the four first bevel gears through the second tooth groove, and the toothed ring is meshed with the four fifth straight gears through the third tooth groove.

[0010] Furthermore, the lower surface of the cover plate is respectively in contact with the upper surfaces of the two protective frames, the upper surfaces of the two vertical frames, and the upper surface of the lifting frame.

[0011] Furthermore, the outrigger is of a U-shaped structure, and the end of the outrigger away from the chassis is of an arc-shaped structure.

[0012] Furthermore, the inner sides of the two protective frames are respectively fitted with the outer surfaces of the two vertical frames and the outer surface of the lifting frame.

[0013] Furthermore, the chassis is a disc structure with an opening at the center of the lower surface and a hollow interior.

[0014] The beneficial effects of a mobile combined digital media audio of the present invention are as follows:

[0015] (1), The present invention is provided with two forms:

[0016] When in use, by controlling the operation of the motor, the lifting frame is raised, the top of the lifting frame pushes against the cover plate, driving a series of transmission structures, causing the protective frame to rotate and open outward. At the same time, all of the audio groups one, two, and three are exposed and face forward, forming an audio matrix so that the audio can exert a more powerful playback effect when in use, meeting the user's demand for high-quality sound effects.

[0017] When the audio is not in use, multiple audio groups can be safely placed; the protective frame protects the audio group three and wraps the audio group two, while the two vertical frames shield and protect the audio group one; effectively avoiding the influence of external collisions, water vapor and other factors on the audio equipment, extending the service life of the audio; at the same time, the volume of the audio after storage is reduced, facilitating storage, transportation and movement, and improving the portability of the audio.

[0018] (2), By providing four universal wheels, the present invention makes the overall audio easy to move; whether it is for indoor venue layout or outdoor venue conversion, the audio can be easily moved to the required position. This provides great convenience for users, especially at large event sites, where the position of the audio can be quickly adjusted to obtain the best sound effect. For example, in exhibition venues, large conferences and other occasions, the mobile function allows the audio to be flexibly adjusted according to different layout requirements.

[0019] When the audio needs to be stably placed for use, the universal wheels are vertically raised and stored inside the through groove through the transmission structure, and at the same time the outriggers rotate to contact the ground to support structures such as the chassis. Ensuring that the audio does not slide due to the rolling of the universal wheels during use, guaranteeing the stability of the audio, and stable placement can avoid affecting the sound quality due to the shaking of the audio.

[0020] (3) The lower surface of the cover plate of the present invention is respectively attached to the upper surfaces of the protective frame, the vertical frame, and the lifting frame, covering the top of the gaps between them; this avoids water stains from flowing in through the gaps and invading the audio equipment inside the structure, effectively preventing equipment damage caused by water ingress. Whether it is rainy weather that may be encountered outdoors or accidental water sprinkling during indoor cleaning, the cover plate can provide good protection for the audio;

[0021] All components of the audio cooperate with each other in the storage state to form a tight whole, providing comprehensive protection for the audio equipment; from the external protective frame and vertical frame to the internal transmission structure, they are all carefully designed to ensure the safety of the audio equipment during transportation and storage; reducing the bumps and vibrations that the audio undergoes during transportation can effectively avoid the influence of these factors on the audio equipment.

Detailed implementation manner

[0034] In the following, the present invention will be described in detail with reference to the drawings and in combination with embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0035] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0036] Refer to Figures 1-10 , a mobile combined digital media audio, including a chassis 1, two vertical frames 2 are fixed on the upper surface of the chassis 1, the rear surface of the vertical frame 2 located at the rear is fixed with a rear frame 3, the top of the rear frame 3 is fixed with a top cover 4, an inner groove 5 is opened inside the top cover 4, a motor 6 is fixed on the upper surface inside the chassis 1, the top end of the output shaft of the motor 6 penetrates through the upper surface of the chassis 1 and is fixed with a first screw 7, a lifting frame 8 is threadedly connected to the outer surface of the first screw 7, the lifting frame 8 is located between the two vertical frames 2, the first audio group 9 is embedded above the front surface of the lifting frame 8, the second audio group 10 is embedded on the front surface of the vertical frame 2 located in the front, two rotating rods 11 are rotatably connected to the upper surface of the chassis 1, the top ends of the rotating rods 11 are located inside the inner groove 5 and are fixed with a first spur gear 12, the outer surface of the first spur gear 12 is meshed with a second spur gear 13, the outer surface of the second spur gear 13 is meshed with a third spur gear 14, a worm gear 15 is fixed in the middle of the third spur gear 14, the outer surfaces of the two worm gears 15 are jointly meshed with a worm 16, a rotating frame 17 is fixed on the outer surface of the worm 16, a cover plate 18 is fixed at the front end of the rotating frame 17, a protective frame 19 is fixed on the outer surface of the rotating rod 11, the third audio group 20 is embedded on the inner side wall of the protective frame 19, the protective frame 19 protects the third audio group 20 inside it and wraps the second audio group 10, and the two vertical frames 2 shield and protect the first audio group 9 inside the lifting frame 8, so that multiple audio groups can be safely placed when stored and not in use, avoiding the influence of external collisions, water vapor and other factors, and also reducing the volume for convenient storage and transportation and movement;

[0037] The bottom end of the rotating rod 11 on the left side penetrates through the chassis 1 and is fixed with a transmission gear 21. The upper surface inside the chassis 1 is rotatably connected with a toothed ring 22. Four second through grooves 24 and four first through grooves 23 are formed on the outer surface of the chassis 1. A second rotating shaft 27 is rotatably connected inside the first through groove 23. A support leg 28 is fixed on the outer surface of the second rotating shaft 27. Above the first through groove 23, a support 25 is fixed. The bottom end of the support 25 is rotatably connected with a first rotating shaft 26. One end of the first rotating shaft 26 located inside the support leg 28 is fixed with a first helical gear 30. One end of the first rotating shaft 26 located inside the chassis 1 is fixed with a fourth spur gear 29. A second helical gear 31 is fixed on the outer surface of the second rotating shaft 27 inside the support leg 28. The second helical gear 31 is meshed and connected with the first helical gear 30.

[0038] A fifth spur gear 32 is rotatably connected to the lower surface inside the second through groove 24. A second screw rod 33 is fixed in the middle of the fifth spur gear 32. A screw plate 34 is threadedly connected to the outer surface of the second screw rod 33. A lifting plate 35 is fixed on the outer surface of the screw plate 34 outside the chassis 1. A universal wheel 36 is fixed on the lower surface of the lifting plate 35. The overall audio can be conveniently moved through the four universal wheels 36. When the fifth spur gear 32 rotates, the second screw rod 33 rotates accordingly, causing the screw plate 34 and the lifting plate 35 to drive the universal wheel 36 to vertically rise, so that the universal wheel 36 is retracted inward and no longer contacts the ground, avoiding the sliding of the audio due to the rollers of the universal wheel 36 during use and making the audio unstable.

[0039] During use, by controlling the operation of the motor 6, the first screw rod 7 rotates, thereby moving the lifting frame 8 upward. During the upward movement of the lifting frame 8, the top of the lifting frame 8 pushes against the cover plate 18, causing it to flip open with the rotating frame 17, driving the worm 16 to rotate, and sequentially causing the rotating rod 11 to rotate and the protective frame 19 to rotate outward through the worm wheels 15, third spur gears 14, second spur gears 13, and first spur gears 12 on both sides, so that the audio group three 20 inside the protective frame 19 is exposed, the audio group one 9 at the lifted lifting frame 8 is exposed, and the audio group two 10 that is no longer blocked by the two protective frames 19 is exposed. At this time, as Figure 9 shown, all the audio groups face forward, forming an audio matrix, making the audio playback effect better.

[0040] At the same time, when the rotating rod 11 on the left side rotates, the toothed ring 22 is rotated through the transmission gear 21 at its bottom, and through the transmission of the toothed ring 22, the fourth spur gear 29 and the fifth spur gear 32 are rotated simultaneously. After the fifth spur gear 32 rotates, the screw plate 34 and the lifting plate 35 drive the universal wheel 36 to rise through the second screw rod 33, so that the universal wheel 36 is retracted into the second through groove 24. After the fourth spur gear 29 rotates, the second rotating shaft 27 and the support leg 28 are rotated sequentially through the first rotating shaft 26, the first helical gear 30, and the second helical gear 31. The outer end of the flipped support leg 28 contacts the ground to support the chassis 1 and other structures, enabling the device to be stably placed and used after moving and during use.

[0041] Refer toFigures 7-8 On the inner surface of the gear ring 22, a number of first tooth grooves 37 are provided. On the lower surface of the gear ring 22, a number of second tooth grooves 38 are provided. On the outer surface of the gear ring 22, a number of third tooth grooves 39 are provided. The gear ring 22 is meshed and connected with the transmission gear 21 through the first tooth grooves 37. The gear ring 22 is meshed and connected with four first helical gears 30 through the second tooth grooves 38. The gear ring 22 is meshed and connected with four fifth spur gears 32 through the third tooth grooves 39. When the transmission gear 21 rotates, it will drive the gear ring 22 to rotate, and the rotating gear ring 22 will drive the fifth spur gears 32 and the fourth spur gear 29 respectively.

[0042] Refer to Figures 3-6 The lower surface of the cover plate 18 is respectively in contact with the upper surfaces of the two protective frames 19, the upper surfaces of the two vertical frames 2, and the upper surface of the lifting frame 8. The cover plate 18 shields the top of the gaps between the protective frame 19, the vertical frame 2, and the lifting frame 8, preventing water stains from flowing down through the gaps and invading the audio equipment inside the structure.

[0043] Refer to Figures 3-6 The inner sides of the two protective frames 19 are respectively in contact with the outer surfaces of the two vertical frames 2 and the outer surface of the lifting frame 8, shielding and protecting the audio group three 20 inside the protective frame 19.

[0044] Refer to Figures 2-7 The support leg 28 is of a U-shaped structure. The end of the support leg 28 away from the chassis 1 is of an arc-shaped structure. The arc end of the support leg 28 contacts the ground after the support leg 28 rotates, enabling the device to be stably supported. The chassis 1 is a disc structure with an opening at the center of the lower surface and a hollow interior, and the hollow interior provides a reasonable layout for other structures.

[0045] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
