Technical Field

[0001] The invention belongs to the technical field of music equipment, in particular to a DSP micro mixer of a mobile pull-bar speaker. Background Art

[0002] Mobile lever speakers are portable sound systems that are often used in outdoor activities, performances, and events. They are lightweight, easy to carry, have clear sound quality, and a large volume, and can meet the sound needs of different occasions. DSP micro mixers are digital signal processing technology tuning devices that can achieve mixing, equalization, delay, and other processing of audio signals, making the sound effects clearer and more realistic. They are often used in professional sound systems and can achieve advanced audio processing effects. DSP micro mixers combined with mobile lever speakers can provide more professional and high-quality sound effects. Users can use the mixer to fine-tune the audio signal, making the music more pleasant and the speech clearer. However, when the traditional DSP micro mixer is idle, its control panel is often exposed to the outside, which is prone to dust accumulation, and the operating buttons are easily damaged by impact, which affects its performance. In addition, the operating angle of the DSP micro mixer is not easy to adjust. Facing operators of different heights, it is necessary to add supports at the bottom to increase the adjustment height. This process is cumbersome and reduces its applicability. To this end, we designed a DSP micro mixer for mobile lever speakers to solve the above problems. Summary of the invention

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a DSP micro mixer for mobile pull-bar audio, comprising a DSP micro mixer and a U-shaped base mounted on the outside of the DSP micro mixer, and a limit mechanism mounted on one side of the DSP micro mixer, an adjustment mechanism is installed at the bottom of the DSP micro mixer, fixed columns are fixedly connected on both sides of the DSP micro mixer, and slots for the fixed columns to move are opened on both sides of the U-shaped base;

[0005] The limiting mechanism includes a fixed block fixedly connected to one side of the DSP micro mixer and through holes penetrating the two ends of the fixed block, and two movable columns slidably connected to the inside of the through holes, one end of the two movable columns is located inside the notch, and the other ends of the two movable columns are respectively and parallelly provided with two tooth plates, the surfaces of the two tooth plates are meshed with gears, and the two ends of the gears are rotatably connected to the inner wall of the through hole, a rectangular groove is opened on one side of the fixed block, a spring is fixedly connected to one side of the rectangular groove, a buffer rod is sleeved inside the spring, one end of the spring is fixedly connected to an L-shaped plate, one end of the L-shaped plate is fixedly connected to one side of the top of the tooth plate, and the other end of the L-shaped plate penetrates to the outside of the rectangular groove and is rotatably connected to a handle;

[0006] The adjustment mechanism includes a U-shaped block fixedly connected to the bottom of the DSP micro mixer, a cylinder passing through both ends of the U-shaped block, and a ratchet fixedly connected to one side of the surface of the cylinder. Two connecting blocks are fixedly connected to the surface of the U-shaped block, and ratchets are rotatably connected to the surfaces of the two connecting blocks. A guide groove is provided on the surface of the ratchet, and a guide rod is movably connected inside the guide groove. One end of the guide rod is fixedly connected to a connecting rod, and the other end of the connecting rod is fixedly connected to one side of the bottom of the L-shaped plate.

[0007] Preferably, both ends of the cylinder passing through the U-shaped block are fixedly connected with H plates, and one end of the H plate is fixedly connected with a rubber pad.

[0008] Preferably, both sides of the inner wall of the through hole are provided with sliding grooves, the interior of the sliding grooves is slidably connected with a protruding block, and one side of the protruding block is fixedly connected to one side of the surface of the movable column.

[0009] Preferably, the width of the DSP micro mixer is smaller than the groove of the U-shaped base, and there is a certain distance between the DSP micro mixer and the groove of the U-shaped base.

[0010] Preferably, the surface of the connecting rod is located on the surface of the fixing block, and the other end of the connecting rod is at a certain distance from the ratchet.

[0011] Preferably, when the guide rod slides in the guide groove from right to left, it can drive the pawl to rotate on the surface of the connecting block, so that the pawl no longer presses against the ratchet wheel and the cylinder can rotate freely.

[0012] Preferably, when the L-shaped plate moves inside the rectangular groove, it drives one tooth plate to move and at the same time drives the other tooth plate to move through the gear, so that the two movable columns move relative to each other.

[0013] Preferably, the fixing column can slide and rotate in the slot, thereby facilitating the flipping of the DSP micro mixer.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The present invention cooperates with a U-shaped base and a limiting mechanism. When the DSP micro mixer is idle, the device can be turned over to hide its operation panel, thereby reducing dust accumulation and reducing the risk of keys on the operation panel being damaged due to bumps. First, hold the handle and push the L-shaped plate to slide in the rectangular groove, and compress the spring at the same time. This action drives the tooth plate connected to the L-shaped plate to move, and through the meshing of the gears, drives the tooth plate on the other side to interact with each other. Subsequently, the two movable columns contract with each other in the through hole. At this time, pull the handle upward to lift one end of the DSP micro mixer upward, and the fixed column at the other end slides to the other end in the notch. At the same time, one end of the DSP micro mixer assembly fixed block also moves to the notch. At this time, keep the handle open, but stop pushing, let the spring reset, drive the tooth plate to move, so that the two movable columns extend from the through hole and are located inside the notch. After completing these steps, the operation panel of the DSP micro mixer will be turned over to the top of the groove of the U-shaped base, effectively protecting the operation panel and reducing the potential impact of dust on the operation panel.

[0016] The present invention optimizes the inclination of the DSP micro mixer by adjusting the angle of the H-plate to meet the use requirements of different operators through the cooperation of the limiting mechanism, the adjusting mechanism and the H-plate. First, hold the handle tightly and push the L-plate to slide in the rectangular groove, while compressing the spring. This action will cause the connecting rod connected to one side of the bottom of the L-plate to move, thereby driving the guide rod to move in the guide groove. The movement of the guide rod causes the pawl to rotate on the surface of the connecting block and no longer contact the ratchet, thereby allowing the cylinder to rotate freely. At this time, under the action of gravity, one end of the H-plate will contact the groove of the U-shaped base, so that one end of the DSP micro mixer is lifted to a suitable angle. After releasing the handle, the spring will reset, the guide rod will move back, and drive the pawl to rotate, so that one end of the pawl will be against the ratchet, limiting the rotation of the cylinder, thereby fixing the position of the H-plate. This design enables the DSP micro mixer to easily adapt to the angle requirements of different operators, significantly improving the applicability and flexibility of the device.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figures 1 to 5 As shown, the present invention provides a DSP micro mixer of a mobile pull-bar sound system, comprising a DSP micro mixer 1 and a U-shaped base 2 mounted on the outside of the DSP micro mixer 1, and a limit mechanism 3 mounted on one side of the DSP micro mixer 1, an adjustment mechanism 4 is installed at the bottom of the DSP micro mixer 1, fixed columns 5 are fixedly connected to both sides of the DSP micro mixer 1, and slots 6 for the fixed columns 5 to move are opened on both sides of the U-shaped base 2;

[0025] The limiting mechanism 3 includes a fixed block 301 fixedly connected to one side of the DSP micro mixer 1 and a through hole 302 penetrating through both ends of the fixed block 301, and two movable columns 303 slidably connected to the inside of the through hole 302, one end of the two movable columns 303 is located inside the notch 6, and the other ends of the two movable columns 303 are respectively and parallelly provided with two tooth plates 304, the surfaces of the two tooth plates 304 are meshed with gears 305, and the two ends of the gear 305 are rotatably connected to the inner wall of the through hole 302, a rectangular groove 306 is opened on one side of the fixed block 301, a spring 307 is fixedly connected to one side of the rectangular groove 306, a buffer rod is sleeved inside the spring 307, one end of the spring 307 is fixedly connected to an L-shaped plate 308, one end of the L-shaped plate 308 is fixedly connected to one side of the top of the tooth plate 304, and the other end of the L-shaped plate 308 penetrates to the outside of the rectangular groove 306 and is rotatably connected to a handle 309;

[0026] The adjustment mechanism 4 includes a U-shaped block 401 fixedly connected to the bottom of the DSP micro mixer 1, a cylinder 402 passing through both ends of the U-shaped block 401, and a ratchet 403 fixedly connected to one side of the surface of the cylinder 402. Two connecting blocks 404 are fixedly connected to the surface of the U-shaped block 401. The surfaces of the two connecting blocks 404 are rotatably connected with pawls 405. The surfaces of the pawls 405 are provided with guide grooves 406. The guide grooves 406 are movably connected with guide rods 407. One end of the guide rod 407 is fixedly connected to a connecting rod 408. The other end of the connecting rod 408 is fixedly connected to one side of the bottom of the L-shaped plate 308.

[0027] like Figures 1 to 5 As shown, the cylinder 402 passes through the U-shaped block 401 and is fixedly connected to an H-plate 7 at both ends, and a rubber pad is fixedly connected to one end of the H-plate 7. The setting of the rubber pad reduces the slippage of the H-plate 7 when it contacts the U-shaped base 2, thereby improving the stability of the H-plate 7 supporting the DSP micro mixer 1;

[0028] like Figures 1 to 5 As shown, both sides of the inner wall of the through hole 302 are provided with slide grooves, and a protrusion is slidably connected inside the slide grooves, and one side of the protrusion is fixedly connected to one side of the surface of the movable column 303. Through the setting of the slide grooves, the movable column 303 can only move horizontally inside the through hole 302 and cannot rotate;

[0029] like Figures 1 to 5 As shown, the width of the DSP micro mixer 1 is smaller than the groove of the U-shaped base 2, and there is a certain distance between the DSP micro mixer 1 and the groove of the U-shaped base 2. The distance between the groove of the U-shaped base 2 and the DSP micro mixer 1 allows the operation panel of the DSP micro mixer 1 to be flipped to the groove of the U-shaped base 2, thereby reducing dust accumulation on the operation panel of the DSP micro mixer 1 and protecting the operation buttons on the operation panel.

[0030] like Figures 1 to 5 As shown, the surface of the connecting rod 408 is located on the surface of the fixed block 301, and the other end of the connecting rod 408 is at a certain distance from the ratchet 403. The distance between the connecting rod 408 and the ratchet 403 prevents the ratchet 403 from colliding with the connecting rod 408 when rotating.

[0031] like Figures 1 to 5 As shown, when the guide rod 407 is located in the guide groove 406 and slides from right to left, the pawl 405 can be driven to rotate on the surface of the connecting block 404, so that the pawl 405 no longer abuts against the ratchet 403, allowing the cylinder 402 to rotate freely. The guide rod 407 slides left and right in the guide groove 406 on the surface of the pawl 405, which can drive the pawl to rotate on the surface of the connecting block 404, thereby making the other end of the pawl 405 descend to abut against the ratchet 403 or rise without abutting against the ratchet 403.

[0032] like Figures 1 to 5 As shown, when the L-shaped plate 308 moves inside the rectangular groove 306, it drives one tooth plate 304 to move, and at the same time drives the other tooth plate 304 to move through the gear 305, so that the two movable columns 303 move relative to each other. Through the setting of the gear 305, when one tooth plate 304 is pushed, the other tooth plate 304 can be driven to move synchronously through the gear 305, thereby causing the two movable columns 303 to produce relative movement;

[0033] like Figures 1 to 5 As shown, the fixing column 5 can slide and rotate in the slot 6, so as to facilitate the flipping of the DSP micro mixer 1. Through the design of the fixing column 5, one end of the DSP micro mixer 1 can slide or rotate in the slots 6 on both sides of the U-shaped base 2 to realize the flipping and angle adjustment of the DSP micro mixer 1.

[0034] The working principle and use process of the present invention:

[0035] Hold the handle 309, and then push the L-shaped plate 308 to slide in the rectangular groove 306, and compress the spring 307 at the same time. This continuous action will activate the tooth plate 304 connected to the L-shaped plate 308, so that it drives the opposite tooth plate 304 to interact with each other through the meshing of the gear 305. Then, the two movable columns 303 will shrink synchronously in the through hole 302. At this time, pull the handle 309 upward to lift one end of the DSP micro mixer 1 upward, and the fixed column 5 at the other end will slide to the opposite side in the slot 6. At the same time, one end of the fixed block 301 assembled with the DSP micro mixer 1 also moves to the position where the fixed column 5 is initially located in the slot 6. At this time, keep the handle 309 intact, but stop pushing, so that the spring 307 is reset, thereby driving the tooth plate 304 to move, so that the two movable columns 303 extend from the through hole 302 and are positioned inside the slot 6. After completing these steps, the operation panel of the DSP micro mixer 1 will be flipped over to the top of the groove of the U-shaped base 2, effectively protecting the operation panel;

[0036] Hold the handle 309 and push the L-shaped plate 308 to slide in the rectangular groove 306, and compress the spring 307 at the same time. This action will cause the connecting rod 408 connected to the bottom side of the L-shaped plate 308 to move, and then drive the guide rod 407 to move in the guide groove 406. The movement of the guide rod 407 makes the pawl 405 rotate on the surface of the connecting block 404 and no longer contact the ratchet 403, thereby allowing the cylinder 402 to rotate freely. At this time, under the action of gravity, one end of the H-plate 7 will contact the groove of the U-shaped base 2, so that one end of the DSP micro mixer 1 is lifted to a suitable angle. After releasing the handle, the spring 307 will reset, and the guide rod 407 will move back accordingly, driving the pawl 405 to rotate, so that one end of the pawl 405 abuts against the ratchet 403, limiting the rotation of the cylinder 402, thereby fixing the position of the H-plate 7, and further supporting the lifting angle of the DSP micro mixer 1. This design enables the DSP micro mixer 1 to easily adapt to the angle requirements of different operators, significantly improving the applicability and flexibility of the device.
