Description

Technical Field

[0001] The present invention relates to the technical field of speakers, and particularly to an active speaker that is convenient to carry and use. Background Art

[0002] In the modern audio equipment market, active speakers are widely welcomed due to their built-in power amplifiers, convenience of directly connecting to sound sources, and excellent sound quality performance. They are not only used by household users for daily entertainment but also play an important role in professional occasions such as concerts, speeches, and outdoor activities. However, despite the many advantages that active speakers offer, they still face some challenges in terms of portability and outdoor use.

[0003] Traditional active speakers, especially those designed for large stages or occasions that require high output power, often integrate complex circuit boards, large-capacity batteries (for portable models), and sturdy housing materials inside the speakers in order to achieve better acoustic effects. These all increase the size and weight of the product. Such a design can provide excellent sound performance, but it brings inconvenience to users in terms of carrying and moving. This inconvenience is particularly obvious for professionals who often need to transport equipment between different locations. Summary of the Invention

[0004] In view of this, the present invention provides an active speaker that is convenient to carry and use, which can solve the drawback that traditional active speakers bring inconvenience to users in terms of carrying and moving.

[0005] The technical implementation solution of the present invention is: an active speaker that is convenient to carry and use, including a speaker housing and a first handle. A first handle is provided at the top of the speaker housing. A fixed frame is installed on the side of the speaker housing. Through holes are provided on the fixed frame. A guide rod is provided inside the fixed frame. A movable plate is slidably arranged on the guide rod. A nitrogen spring is provided inside the fixed frame. The telescopic rod of the nitrogen spring is connected to the movable plate. A connecting plate is connected to the movable plate. A conduit is slidably arranged on the fixed frame. The bottom end of the conduit is connected to the top of the connecting plate. A movable rod is slidably arranged inside the conduit. The top end of the movable rod is connected to a second handle. A limiting mechanism is provided on the speaker housing for limiting the movable rod. A support frame is provided at the bottom of the speaker housing. A lifting plate is slidably arranged on the support frame. The lifting plate is located inside the speaker housing. Universal wheels are rotatably arranged at intervals at the bottom of the lifting plate. A clamping mechanism is provided on the support frame for limiting the support frame.

[0006] Optionally, the limiting mechanism includes a limiting frame and a first spring. Grooves are provided on the movable rod. A limiting frame is slidably arranged on the speaker housing. The limiting frame is used to be inserted into the grooves to limit the movable rod. A first spring is provided between the limiting frame and the speaker housing.

[0007] Optionally, the clamping mechanism includes an L-shaped limiting plate, a movable frame, and a fixed rod. The L-shaped limiting plates are symmetrically arranged on the support frame. A movable frame is slidably arranged between the two L-shaped limiting plates. A clamping groove is formed on the movable frame. A fixed rod is connected to the lifting plate. The support frame is limited by clamping the fixed rod into the clamping groove of the movable frame.

[0008] Optionally, it further includes a connecting rope. The two ends of the connecting rope are respectively connected to the movable plate and the movable frame, so that when the movable plate moves, the movable frame is pulled to move through the connecting rope.

[0009] Optionally, it further includes a guiding mechanism. The guiding mechanism includes a connecting block, a rotating shaft, and a guiding wheel. The connecting block is installed on the support frame. The rotating shaft is rotatably arranged on the connecting block. The guiding wheel is arranged on the rotating shaft and is used to guide the connecting rope.

[0010] Optionally, it further includes a second spring. The second spring is arranged inside the movable frame. One end of the second spring is connected to the movable frame, and the other end of the second spring is connected to the inner wall of the sound box housing. The second spring is used to drive the movable frame to move back to its original position.

[0011] Optionally, it further includes a wire reel. The wire reel is installed on the side of the sound box housing and is used to wind the power cord.

[0012] Optionally, it further includes rubber clamping plates. The rubber clamping plates are symmetrically installed on the side of the sound box housing and are used to clamp the connector at the end of the power cord to fix the connector at the end of the power cord.

[0013] The present invention has the following advantages: 1. By arranging the first handle on the top of the sound box housing in the present invention, cooperating with the universal wheels on the support frame below the sound box housing, and combining with the telescopic second handle, the user can adjust the height of the handle according to needs, greatly improving the convenience and comfort of carrying the speaker. Moreover, the application of the nitrogen spring realizes the automatic lifting of the second handle, reducing the manual operation steps and further enhancing the portability.

[0014] 2. When the speaker is placed on the ground in the present invention, the universal wheels on the support frame will contact the ground, while the bottom of the speaker is separated from the ground. This design not only protects the bottom of the speaker from wear, but also ensures the stability of the speaker in the moving state through the clamping mechanism between the fixed rod and the movable frame.

[0015] 3. By introducing the connecting rope, the guiding mechanism and the second spring in the present invention, some manual operations are replaced, such as pulling the movable frame to move back to its original position. This not only reduces the burden on the user, but also improves the operation efficiency, especially when the speaker is frequently moved, the advantage is particularly obvious.

[0032] Embodiment: An active speaker that is convenient to carry and use. Refer to Figures 1-8 As shown, it includes a speaker housing 1 and a first handle 2; a first handle 2 is provided on the top of the speaker housing 1; It further includes a fixed frame 3, guide rods 4, a movable plate 5, a nitrogen spring 6, a connecting plate 7, a conduit 8, a movable rod 9, a second handle 10, a limiting mechanism, a support frame 12, a lifting plate 13, universal wheels 14 and a clamping mechanism; A fixed frame 3 is installed on the left side of the audio shell 1, and a through hole 301 is opened at the lower left side of the fixed frame 3; Guide rods 4 are symmetrically arranged before and after inside the fixed frame 3; A movable plate 5 is slidably arranged between the two guide rods 4; Nitrogen springs 6 are symmetrically arranged before and after at the lower part inside the fixed frame 3, the two guide rods 4 are located between the two nitrogen springs 6, and the telescopic rods of the two nitrogen springs 6 are both connected to the movable plate 5; The middle part of the lower side of the movable plate 5 is connected with a connecting plate 7; Conduits 8 are symmetrically slidably arranged before and after on the fixed frame 3; The bottom ends of the two conduits 8 are both connected to the top of the connecting plate 7; A movable rod 9 is slidably arranged inside the conduit 8, the top end of the movable rod 9 exceeds the top end of the conduit 8, and the top end of the movable rod 9 is located outside the fixed frame 3; A second handle 10 is connected between the top ends of the two movable rods 9; A limiting mechanism is arranged on the audio shell 1, and the limiting mechanism is used to limit the movable rod 9; A support frame 12 is arranged at the bottom of the audio shell 1; A lifting plate 13 is slidably arranged on the upper side of the support frame 12, and the lifting plate 13 is located inside the audio shell 1; Four universal wheels 14 are rotatably arranged at intervals at the bottom of the lifting plate 13; A clamping mechanism is arranged on the support frame 12, and the clamping mechanism is used to limit the support frame 12.

[0033] See Figures 2-4 As shown, the limiting mechanism includes a limiting frame 1102 and a first spring 1103; A groove 1101 is opened at the upper right side of the movable rod 9; A limiting frame 1102 is slidably arranged at the upper left side of the audio shell 1, and the limiting frame 1102 is clamped into the groove 1101 to limit the movable rod 9; Four first springs 1103 are arranged between the right side of the limiting frame 1102 and the upper left side of the audio shell 1.

[0034] See Figure 7 and Figure 8 As shown, the clamping mechanism includes an L-shaped limiting plate 1501, a movable frame 1502 and a fixed rod 1504; L-shaped limiting plates 1501 are symmetrically arranged before and after on the support frame 12, and the L-shaped limiting plates 1501 are located inside the audio shell 1; A movable frame 1502 is slidably arranged between the two L-shaped limiting plates 1501, and a clamping groove 1503 is opened on the movable frame 1502; A fixed rod 1504 is connected to the middle part of the lifting plate 13, and by clamping the fixed rod 1504 into the clamping groove 1503 of the movable frame 1502, the support frame 12 can be limited.

[0035] In the initial state, since the limiting frame 1102 is clamped into the groove 1101 to limit the movable rod 9, the movable rod 9 presses the conduit 8, the connecting plate 7 and the movable plate 5, so that the movable plate 5 presses the telescopic rod of the nitrogen spring 6, so that the telescopic rod of the nitrogen spring 6 is in a compressed state; When it is necessary to carry the active speaker for movement, first lift the first handle 2, so that the first handle 2 drives the speaker housing 1 and the support frame 12 to move upward, separating the bottom of the speaker housing 1 from the ground, while the universal wheels 14 on the lifting plate 13 continue to contact the ground. Then, the operator inserts his hand into the fixing frame 3 and the speaker housing 1 through the through hole 301, and then pulls the movable frame 1502 to move leftward until the fixing rod 1504 is inserted into the slot 1503 in the movable frame 1502, making the fixing rod 1504 press against the movable frame 1502, thereby limiting the support frame 12. Then, the operator withdraws his hand from the through hole 301 and releases the first handle 2. At this time, using the limitation of the support frame 12 by the fixing rod 1504 can prevent the speaker housing 1 and the support frame 12 from falling downward due to gravity. Then, press the limiting frame 1102 to move rightward, and the first spring 1103 is compressed, so that the limiting frame 1102 leaves the groove 1101, thereby releasing the limitation of the movable rod 9 by the limiting frame 1102. At this time, the nitrogen spring 6 returns to its original state, and the nitrogen spring 6 drives the movable plate 5, the connecting plate 7, the conduit 8, the movable rod 9 and the second handle 10 to move upward, thereby automatically raising the second handle 10. Then, release the limiting frame 1102. Affected by the elastic force of the first spring 1103, the first spring 1103 will drive the limiting frame 1102 to move leftward until the limiting frame 1102 contacts the movable rod 9. After that, the operator pulls the second handle 10 upward according to the need, so that the second handle 10 drives the movable rod 9 to move upward, thereby making the movable rod 9 extend out of the conduit 8 until the height of the second handle 10 is suitable for the operator to pull the active speaker for movement. Subsequently, the operator pulls the active speaker for movement, making the universal wheels 14 roll on the ground. In this way, it is convenient for the operator to carry the active speaker for movement; After moving the active speaker to the designated position, press the second handle 10 to move it downward, causing the second handle 10 to drive the movable rod 9 to move downward, so that the movable rod 9 retracts into the conduit 8. Then continue to press the second handle 10 to move downward, causing the second handle 10 to drive the movable rod 9, conduit 8, connecting plate 7 and movable plate 5 to move downward and reset, so that the movable plate 5 squeezes the telescopic rod of the nitrogen spring 6, causing the telescopic rod of the nitrogen spring 6 to be in a compressed state. When the groove 1101 on the movable rod 9 aligns with the limit frame 1102, the first spring 1103 returns to its original state, and the first spring 1103 drives the limit frame 1102 to move leftward and reset, so that the limit frame 1102 is reinserted into the groove 1101 to limit the movable rod 9. Then release the second handle 10, hold the first handle 2, and then the operator puts his hand into the fixed frame 3 and the speaker housing 1 through the through hole 301, and then pushes the movable frame 1502 to move rightward and reset, so that the fixed rod 1504 leaves the card slot 1503 in the movable frame 1502. Then the operator withdraws his hand from the through hole 301 and slowly releases the first handle 2. At this time, affected by the gravity of the support frame 12 and the speaker housing 1, the support frame 12 and the speaker housing 1 will slowly fall downward until the bottom of the speaker housing 1 touches the ground, thereby increasing the friction between the active speaker and the ground and improving the stability of the active speaker.

[0036] See Figure 7 and Figure 8 As shown, it further includes a connecting rope 16; the number of the connecting ropes 16 is two, and both ends of the connecting rope 16 are respectively connected to the bottom of the movable plate 5 and the lower left side of the movable frame 1502, so that when the movable plate 5 moves, it can drive the movable frame 1502 to move through the connecting rope 16.

[0037] By setting the connecting rope 16, when it is necessary to put the hand into the fixed frame 3 and the speaker housing 1 through the through hole 301 and pull the movable frame 1502 to move leftward, the limit frame 1102 can be directly pressed to move rightward; when the movable plate 5 moves upward, the movable plate 5 will drive the movable frame 1502 to move leftward through the connecting rope 16, thus replacing manual operation to automatically pull the movable frame 1502 to move leftward, which is convenient for the operator to use.

[0038] See Figure 7 and Figure 8 As shown, it further includes a guiding mechanism, and the guiding mechanism includes a connecting block 17, a rotating shaft 18 and a guiding wheel 19; a connecting block 17 is installed on the support frame 12, and the connecting block 17 is located on the left side between the two L-shaped limiting plates 1501; a rotating shaft 18 is rotatably arranged on the upper side of the connecting block 17, and guiding wheels 19 are arranged on both the front and rear sides of the rotating shaft 18. The two connecting ropes 16 respectively bypass the two guiding wheels 19, and the guiding wheels 19 are used for guiding the connecting ropes 16.

[0039] By setting up a guiding mechanism, the guiding wheel 19 can be used to guide the connecting rope 16, thereby preventing the connecting rope 16 from contacting the left side of the lifting plate 13 and avoiding wear of the connecting rope 16 by the left side of the lifting plate 13 during movement.

[0040] See Figures 7-9 As shown, it further includes a second spring 20; the second spring 20 is arranged inside the movable frame 1502. The left end of the second spring 20 is connected to the movable frame 1502, and the right end of the second spring 20 is connected to the inner right wall of the speaker housing 1. The second spring 20 is used to drive the movable frame 1502 to move back to its original position.

[0041] By setting up the second spring 20, when the movable plate 5 moves upward, the movable plate 5 will drive the movable frame 1502 to move leftward through the connecting rope 16, stretching the second spring 20; when the movable plate 5 moves downward and returns to its original position, the movable plate 5 will release the connecting rope 16. At this time, the second spring 20 returns to its original state, and the second spring 20 drives the movable frame 1502 to move rightward to return to its original position, thereby automatically pushing the movable frame 1502 to move rightward to return to its original position instead of manual operation, which is convenient for the operator to use.

[0042] See Figure 10 and Figure 11 As shown, it further includes a wire reel 21; the wire reel 21 is installed in the middle of the rear side of the speaker housing 1. The wire reel 21 is used for coiling the power cord.

[0043] By setting up the wire reel 21, when carrying this active speaker and moving it, the power cord on this active speaker can be coiled on the wire reel 21, thereby organizing the power cord to prevent the scattered power cord from affecting the operator's carrying of this active speaker.

[0044] See Figure 10 and Figure 11 As shown, it further includes rubber clamping plates 22; two groups of rubber clamping plates 22 are symmetrically installed on the lower part of the rear side of the speaker housing 1. The number of rubber clamping plates 22 in one group is two, and the two rubber clamping plates 22 in each group are distributed left and right. Each group of rubber clamping plates 22 is used to clamp the connector at the end of the power cord to fix the connector at the end of the power cord.

[0045] By setting up the rubber clamping plates 22, after the power cord is organized, the connector at the end of the power cord can be snapped into the rubber clamping plates 22 for fixation to prevent the connector at the end of the power cord from swinging randomly and hitting surrounding objects, resulting in damage.

[0046] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
