Description

Technical Field

[0001] The utility model relates to the technical field of audio engineering, and specifically relates to a waterproof and drop-resistant loudspeaker. Background Technique

[0002] A loudspeaker is actually a conversion device that converts electrical energy into sound. When different electrical energies are transmitted to the coil, the coil generates an energy that interacts with the magnetic field of the magnet. This interaction causes the paper disc to vibrate. Because the electrical energy changes at any time, the coil of the loudspeaker will move forward or backward. Therefore, the paper disc of the loudspeaker will move accordingly. These movements cause changes in the density of the air and generate sound.

[0003] When most existing loudspeakers are used outdoors, they may encounter rainy weather, which may cause rainwater to enter the inside of the loudspeaker, resulting in malfunctions of the loudspeaker. At the same time, most existing loudspeakers do not have a shock-absorbing and protective structure, which may cause damage to the sound-emitting unit when the loudspeaker is collided or dropped. Therefore, those skilled in the art have provided a waterproof and drop-resistant loudspeaker to solve the problems raised in the above background technique. Content of the Utility Model

[0004] The purpose of the utility model is to provide a waterproof and drop-resistant loudspeaker to solve the technical problems existing in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A waterproof and drop-resistant loudspeaker includes a protective shell, a loudspeaker shell, and a sound-emitting unit. Rotating rods are rotatably embedded at the upper ends of the left and right sides of the outer surface of the loudspeaker shell. Screws are threadedly embedded on the opposite sides of the two rotating rods. Embedding blocks are fixedly arranged on the opposite sides of the two screws. A waterproof diaphragm is embedded on the upper end surface of the loudspeaker shell. An annular fixing block is fixedly arranged on the outer side of the lower end surface of the waterproof diaphragm. A water accumulation plate is fixedly arranged on the upper end surface of the inner surface of the loudspeaker shell;

[0007] Clamping mechanisms are fixedly embedded on the front, rear, left, and right sides and the upper ends of the outer surface of the protective shell. Each clamping mechanism includes a rotating cylinder, a clamping shell, a movable block, a threaded rod, a clamping block, and two spring telescopic rods. The two spring telescopic rods are respectively fixedly arranged at the midpoints of the inner top surface and the inner bottom surface of the clamping shell. The movable block is arranged between the two spring telescopic rods. The rotating cylinder is rotatably embedded on one side of the movable block. The threaded rod is threadedly embedded on one side of the rotating cylinder. The clamping block is fixedly arranged on one side of the threaded rod.

[0008] Further, the clamping blocks of the four clamping mechanisms are respectively and correspondingly embedded and connected to the midpoints of the front and rear sides and the left and right sides of the outer surface of the horn housing, and the clamping housings of the four clamping mechanisms are respectively embedded and arranged inside the upper ends of the front and rear sides and the left and right sides of the protective housing.

[0009] Further, the annular fixing block is embedded and arranged inside the outer side of the upper end surface of the horn housing, and the two embedding blocks are respectively and correspondingly embedded and connected to the midpoints of the left and right sides of the annular fixing block.

[0010] Further, clamping plates are fixedly arranged on both the left and right sides of the sound generating unit, and embedding plates are fixedly arranged on both the left and right sides of the inner surface of the horn housing.

[0011] Further, the two clamping plates are respectively embedded and arranged on the upper end surfaces of the two embedding plates, and bolts are respectively embedded and arranged on one side of the upper end surfaces of the two clamping plates.

[0012] Further, annular rubber pads are fixedly arranged on both the upper end surface and the lower end surface of the protective housing, and water guide grooves are respectively opened at the midpoints of both the left and right sides of the inner surface of the horn housing.

[0013] Compared with the prior art, the advantages of the present utility model are as follows:

[0014] 1. For a waterproof and drop-resistant horn proposed by the present utility model, after clamping mechanisms are fixedly embedded on the left and right sides and the front and rear sides of the outer surface of the protective housing, the horn housing can be clamped between the four clamping mechanisms, so as to fix the horn housing. At the same time, through the spring telescopic rods fixedly arranged inside the clamping mechanisms, when the horn housing is collided or dropped, it can play a role in shock absorption and buffering, thereby protecting the horn housing and the sound generating unit.

[0015] 2. For a waterproof and drop-resistant horn proposed by the present utility model, after rotating rods are rotatably embedded on the left and right sides of the outer surface of the upper end of the horn housing, the screw rod fixed with the embedding block can be driven to expand and contract during rotation, so as to be correspondingly embedded and connected to the annular fixing block fixedly arranged on the lower end surface of the waterproof vibration membrane embedded in the upper end surface of the horn housing, thereby realizing the embedding and fixing of the waterproof vibration membrane. When the waterproof vibration membrane is clamped and fixed on the upper end surface of the horn housing, the waterproof vibration membrane can play a certain waterproof role for the internal sound generating unit. At the same time, by fixedly arranging a water accumulation plate inside the upper end of the horn housing, the water flowing in through the gap between the waterproof vibration membrane and the upper end surface of the horn housing can be stored, and then the stored water can be discharged through the water guide grooves opened on the horn housing, thereby achieving a better waterproof effect for the inside of the horn.

An annular fixing block 12 is fixedly arranged on the outer side of the lower end surface of the waterproof diaphragm 3. A water accumulation plate 7 is fixedly arranged on the inner surface of the speaker housing 4 near the upper end. After fixedly arranging the annular fixing block 12 on the lower end surface of the waterproof diaphragm 3, the waterproof diaphragm 3 can be embedded on the upper end surface of the speaker housing 4; Rotating blocks are fixedly arranged on the opposite sides of the two rotating rods 8. By rotating the fixedly arranged rotating blocks, the rotating rods 8 can be better driven to rotate. When the rotating rods 8 rotate, the screw rods 13 fixed with the embedding blocks 14 can be driven to perform telescopic adjustment, so that they can be engaged and connected with the annular fixing block 12, and then the waterproof diaphragm 3 can be clamped and fixed;

[0026] Clamping mechanisms 2 are fixedly embedded on the front, back, left and right sides near the upper ends of the outer surface of the protective housing 1. After fixedly embedding the clamping mechanisms 2 at the midpoints of the left and right sides and the front and back sides of the protective housing 1, the speaker housing 4 can be clamped and fixed in the protective housing 1.

[0027] Specifically, in the above specific embodiments, each clamping mechanism 2 includes a rotating cylinder 201, a clamping outer shell 202, a movable block 203, a threaded rod 204, a clamping block 205, and two spring telescopic rods 206; the two spring telescopic rods 206 are respectively fixedly arranged at the midpoints of the inner top surface and the inner bottom surface of the clamping outer shell 202, the movable block 203 is arranged between the two spring telescopic rods 206, the rotating cylinder 201 is rotatably embedded on one side of the movable block 203, the threaded rod 204 is threadedly embedded on one side of the rotating cylinder 201, and the clamping block 205 is fixedly arranged on one side of the threaded rod 204. After fixedly arranging the two spring telescopic rods 206 on the inner bottom surface and the inner top surface of the clamping outer shell 202, an up-and-down movable movable block 203 can be arranged between the two spring telescopic rods 206. After clamping and embedding the horn outer shell 4 between the four clamping mechanisms 2, when the horn outer shell 4 is collided, it can drive the movable block 203 in the clamping mechanism 2 to move up and down.

[0028] Specifically, in the above specific embodiments, each movable block 203 is movably arranged between the inner walls on the left and right sides of the corresponding clamping outer shell 202; more specifically, the outer walls on the left and right sides of each movable block 203 are respectively in contact with the inner walls on the left and right sides of the corresponding clamping outer shell 202, and the outer walls on the upper and lower sides of each movable block 203 are respectively connected to the inner top surface and the inner bottom surface of the corresponding clamping outer shell 202 through the spring telescopic rods 206; when the movable block 203 moves, it can only be adjusted up and down and cannot move left and right.

[0029] Specifically, in the above specific embodiments, the clamping blocks 205 of the four clamping mechanisms 2 are respectively in one-to-one correspondence and fitted connection with the midpoints of the front and rear sides and the left and right sides of the outer surface of the horn outer shell 4, and the clamping outer shells 202 of the four clamping mechanisms 2 are respectively embedded in the upper inner parts of the front and rear sides and the left and right sides of the protective outer shell 1. After fitting and connecting the clamping blocks 205 of the four clamping mechanisms 2 with the outer surface of the horn outer shell 4, the horn outer shell 4 can be clamped and fixedly arranged inside the protective outer shell 1. At the same time, after fixedly embedding the clamping outer shells 202 of the four clamping mechanisms 2 in the protective outer shell 1, the clamping mechanisms 2 can be better fixed.

[0030] Specifically, in the above specific embodiment, the annular fixing block 12 is embedded in the inner part of the outer side of the upper end surface of the horn housing 4, and the two embedding blocks 14 are respectively and correspondingly embedded and connected to the midpoints of the left and right sides of the annular fixing block 12.

[0033] Specifically, in the above specific embodiment, annular rubber pads 5 are fixedly provided on both the upper end surface and the lower end surface of the protective housing 1, and water guide grooves 15 are formed at the midpoints of both the left and right sides of the inner surface of the horn housing 4. After the annular rubber pads 5 are fixedly provided on the upper end surface and the lower end surface of the protective housing 1, the buffering effect when the protective housing 1 drops can be further improved. At the same time, the water accumulated in the water accumulation plate 7 can be discharged through the water guide grooves 15 formed in the horn housing 4, avoiding the overflow of the accumulated water into the inside of the horn housing 4 when the accumulated water is too much.

[0034] The working principle of the waterproof and drop-resistant horn provided by the present utility model is as follows:

[0035] In use, the user can first fixedly clamp the sound generating unit 6 inside the horn housing 4 through the bolt 11, and then embed the waterproof diaphragm 3 on the upper end face of the horn housing 4. After that, by rotating the two rotating rods 8 fixed with rotating blocks, the two screws 13 fixed with embedding blocks 14 can be driven to expand and contract, so as to be engaged with the annular fixing block 12, and then the waterproof diaphragm 3 can be fixedly engaged. When the horn housing 4 is arranged in the protective housing 1, by rotating the rotating cylinders 201 fixed with knobs in the four clamping mechanisms 2, the threaded rods 204 and the clamping blocks 205 can be driven to engage with the horn housing 4, so as to clamp and fix the horn housing 4, playing a role in shock absorption and buffering for the horn housing 4.
