Description

Technical Field

[0001] This utility model relates to the field of audio equipment technology, specifically a portable speaker. Background Technology

[0002] A speaker is a device that converts audio signals into sound. In simpler terms, it refers to a speaker enclosure or subwoofer enclosure that has a built-in power amplifier that amplifies the audio signal before the speaker itself reproduces the sound, making it louder.

[0003] In daily life, with the advancement of technology and the improvement of people's living standards, outdoor speakers have become an indispensable part of modern life. Especially in outdoor activities or gatherings, outdoor speakers can provide a good user experience. However, in actual use, since the speakers are located outdoors for a long time, the impurities entering the speaker from the outdoors that cause damage are much higher than those indoors. To protect against dust, existing speakers are covered with a protective shell, which usually reduces the sound quality when used outdoors to achieve a better protection effect. However, the reduction in sound quality will affect the use and the listener's experience, thus affecting the user experience in outdoor activities or gatherings. Utility Model Content

[0014] As a further embodiment of this utility model, a limit strip is provided on the outer wall of the outer shell.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. A portable speaker of this utility model, when music needs to be played, can be manually moved to lower the first handle, which in turn lowers the first protective plate. Under the guidance of two first guide rails, the first protective plate enters the first storage slot and is stored in the first storage slot, so that the first protective plate is away from the first sound transmission slot. This allows the sound emitted by the speaker body to be transmitted to the outside from the first sound transmission slot, making it convenient to listen to. At the same time as the first handle is moved, the connecting component and two second sliding components slide together. When the first protective plate moves, the two second protective plates move together, so that the second protective plates move away from the two second sound transmission slots in corresponding positions, allowing the sound emitted by the speaker body to be transmitted better.

[0017] When protection of the speaker is required, the first protective plate is raised by manually moving the first handle. The raised protective plate covers the first sound-permeable groove, preventing dust and other objects from entering the casing and causing damage to the speaker body during handling. The casing can be opened or closed by simply moving the first handle down or up. Moving the first handle down does not affect the sound quality of the speaker body when playing music. The first sound-permeable groove and two second sound-permeable grooves on the casing are opened or closed, thus allowing for convenient operation of the speaker.

[0018] 2. In a portable speaker of this utility model, when the first sound-permeable groove and the two second sound-permeable grooves are sealed, as the first handle is manually moved to rise, the first protective plate is also moved to rise, and the locking block on one side of the first protective plate is also moved to rise. By limiting the locking block, the locking block is prevented from falling off, thereby preventing the first protective plate from falling off and providing better protection for the speaker.

[0019] When music needs to be played, manually move the sliding rod away from the end of the stop block, causing the sliding rod to slide the stop block on the U-shaped frame until the stop block moves away from the locking block. This allows the locking block to lower the first protective plate, thus storing the first protective plate for easy music playback.

[0020] 3. The portable speaker of this utility model has a lifting frame on the top of the shell, which allows people to carry the speaker in its protective state by hand lifting frame 28, making it easy to change the position of the speaker, thereby achieving the effect of portability. Combined with the protective effect of the first protective plate and two second protective plates, it provides better protection for the speaker when it is moved. Attached Figure Description

[0030] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0031] The present invention provides the following preferred embodiments:

[0032] Example 1, as Figures 1-8 As shown, a portable speaker includes an outer shell 27 disposed on the outer wall of the speaker body 1, and also includes a lifting frame 28, a first sound-permeable groove 23, a protective mechanism, a locking mechanism, and two second sound-permeable grooves 24. The outer shell 27 is fitted onto the outer wall of the speaker body 1. The first sound-permeable groove 23 is opened on one side of the outer shell 27, and the two second sound-permeable grooves 24 are respectively disposed at both ends of the outer shell 27. The lifting frame 28 is fixedly disposed on the top of the outer shell 27. By providing the lifting frame 28 on the top of the outer shell 27, a person can carry the speaker in its protective state by hand using the lifting frame 28 for portable movement, making it convenient to change the position of the speaker.

[0033] The protective mechanism includes a first protective plate 2, two second protective plates 3, a first sliding assembly, a connecting assembly, and two second sliding assemblies. The first sliding assembly is disposed on the side of the housing 27 near the first sound-permeable groove 23, and each second sliding assembly is disposed on the side of the housing 27 near a second sound-permeable groove 24. The first protective plate 2 is slidably disposed on the first sliding assembly, and each second protective plate 3 is slidably disposed on a second sliding assembly.

[0034] The locking mechanism includes two locking blocks 4 and two limiting components. The two locking blocks 4 are respectively located on both sides of the first protective plate 2, and each limiting component is located on one side of one locking block 4.

[0035] like Figures 1-8 As shown, it includes a first protective plate 2, a first storage slot 5, a first handle 6, two first clearance slots 7 and two first guide rails 8. The first storage slot 5 is provided inside the outer shell 27. The two first guide rails 8 are respectively fixedly arranged on both sides inside the first storage slot 5. The first protective plate 2 is slidably arranged between the two first guide rails 8. The two first clearance slots 7 are all opened on the outer wall of the outer shell 27. The first handle 6 passes through the two first clearance slots 7 and is fixedly connected to the first protective plate 2.

[0036] When music needs to be played, the first handle 6 is manually moved down, causing the first protective plate 2 to descend. Guided by the two first guide rails 8, the first protective plate 2 enters the first storage slot 5 and is stored in the first storage slot 5, moving it away from the first sound transmission slot 23. This allows the sound emitted by the speaker body 1 to be transmitted to the outside from the first sound transmission slot 23, making it easier to listen to. When the first handle 6 is moved, the connecting component and the two second sliding components slide together. As the first protective plate 2 moves, the two second protective plates 3 also move together, moving the second protective plates 3 away from the two second sound transmission slots 24 at their corresponding positions, allowing the sound emitted by the speaker body 1 to be transmitted better.

[0037] When the speaker needs to be moved, the first handle 6 is manually moved upwards, which in turn moves the first protective plate 2 upwards. The first protective plate 2 covers the first sound-permeable groove 23, preventing dust and other objects from entering the outer shell 27 and damaging the speaker body 1 during handling. The outer shell 27 can be opened or closed simply by moving the first handle 6 downwards or upwards. Moving the first handle 6 downwards does not affect the sound quality of the speaker body 1 when playing music.

[0038] like Figures 1-8As shown, each second sliding component includes a second storage slot 11, a second handle 12, two second clearance slots 13 and two second guide rails 14. The outer wall of the housing 27 is provided with a second storage slot 11. The two second guide rails 14 are respectively fixedly arranged on both sides inside the second storage slot 11. One of the second protective plates 3 is slidably arranged between the second guide rails 14. The two second clearance slots 13 are both opened on the outer wall of the housing 27. The second handle 12 passes through the two second clearance slots 13 and is fixedly connected to the second protective plate 3.

[0039] When the first protective plate 2 moves, it will drive the two second handles 12 to move simultaneously through the connecting component. When the second handle 12 moves, it will drive the corresponding second protective plate 3 to move together, so that the second protective plate 3 moves under the guidance of the two second guide rails 14. The second protective plate 3 is stored in the second storage slot 11. By moving the first handle 6 down or up, the two second protective plates 3 can be moved together through the connecting component, opening or closing the first sound transmission slot 23 and the two second sound transmission slots 24 opened in the outer shell 27, thereby making the speaker easy to operate.

[0040] like Figures 1-8 As shown, the connecting assembly includes two connecting rods 16, two guide rods 17, and two guide grooves 18. Both ends of each connecting rod 16 are fixedly connected to a first handle 6 and a second handle 12. Each guide rod 17 is fixedly disposed on the outer wall surface of the housing 27. Each guide groove 18 is fixedly disposed on the side of a connecting rod 16 near the housing 27, and each guide groove 18 is slidably connected to a guide rod 17.

[0041] When the first handle 6 is turned, the two connecting rods 16 on both sides of the first handle 6 will move. The two connecting rods 16 will drive the two second handles 12 to move simultaneously, so as to open or close the first sound-permeable groove 23 and the two second sound-permeable grooves 24 at the same time. When the two connecting rods 16 move, the guide groove 18 set on one side of the connecting rod 16 slides on the guide rod 17 fixed on the outer wall surface of the housing 27, which guides the movement of the connecting rod 16, thereby driving the two second handles 12 to move simultaneously.

[0042] like Figures 1-8 As shown, each limiting component includes a stop block 19, a sliding rod 20, a spring 21, and a U-shaped frame 22. The U-shaped frame 22 is fixedly installed on the outer wall of the housing 27 and located on the top of one of the first guide rails 8. The sliding rod 20 is slidably installed on the U-shaped frame 22. The stop block 19 is fixedly installed on one end of the sliding rod 20. The two ends of the spring 21 are fixedly connected to one side of the stop block 19 and one side of the U-shaped frame 22, respectively. Each locking block 4 is fixedly installed on one side of the first protective plate 2. One side of the stop block 19 is in contact with one side of one of the locking blocks 4.

[0043] When the first sound-permeable groove 23 and the two second sound-permeable grooves 24 are sealed, as the first handle 6 is manually moved upward, the first protective plate 2 is also moved upward, which in turn moves the locking block 4 on one side of the first protective plate 2 upward. During the upward movement of the locking block 4, it will come into contact with the abutment block 19 on one side. As the locking block 4 rises, it will contact the abutment block 19 and squeeze the abutment block 19, causing the abutment block 19 to drive the sliding rod 20 to slide on the U-shaped frame 22. During the movement, the abutment block 19 will move closer to the U-shaped frame 22, thus... The spring 21 is compressed, and the spring 21 extends and retracts. When the first protective plate 2 continues to rise, it will drive the locking block 4 to continue to rise until the locking block 4 passes through the abutment block 19. At this time, since the abutment block 19 is not resisted by the locking block 4, the spring 21 will reset. Driven by the spring 21, the abutment block 19 will move to one side of the locking block 4 and move to the position of the locking block 4 to limit the locking block 4 and prevent the locking block 4 from falling, thereby preventing the first protective plate 2 from falling and improving the protective stability of the first protective plate 2.

[0044] When music needs to be played, the sliding rod 20 is manually grasped to pull the stop block 19 away from the end of the locking block 4. This causes the sliding rod 20 to slide the stop block 19 on the U-shaped frame 22 until the stop block 19 moves away from the locking block 4. This allows the locking block 4 to lower the first protective plate 2 for storage, making it convenient to play music.

[0045] like Figures 1-8 As shown, the speaker body 1 has a main sound outlet 25 on the side near the first sound-permeable groove 23, and a secondary sound outlet 26 on each side near the two second sound-permeable grooves 24. The speaker body 1 plays music through the main sound outlet 25 and the two secondary sound outlets 26. The first sound-permeable groove 23 and the two second sound-permeable grooves 24 correspond to the main sound outlet 25 and the two secondary sound outlets 26. The first protective plate 2 and the two second protective plates can close or open the first sound-permeable groove 23 and the two second sound-permeable grooves 24, thereby facilitating the playback or protection of the speaker body 1.

[0046] like Figures 1-8 As shown, the outer wall of the outer shell 27 is provided with a limiting strip 10. The limiting strip 10 is used to limit the first protective plate 2 to prevent the first protective plate 2 from rising and deviating from the first sound-permeable groove 23.
