Description

Technical Field

[0001] This invention belongs to the field of audio technology, specifically relating to an intrinsically safe voice speaker with recording function. Background Technology

[0002] Intrinsically safe, also known as intrinsically safe, is the safest type of explosion-proof enclosure. Intrinsically safe products, whether internally short-circuited or otherwise, will not cause an explosion of flammable or explosive gases in the surrounding environment. Therefore, intrinsically safe speakers can also be called explosion-proof speakers, and are commonly used in mining applications.

[0003] Existing intrinsically safe speakers tend to accumulate dust at the sound outlet during prolonged use. Over time, this can impede sound wave emission from the enclosure, resulting in a less loud sound. While some existing speakers offer dust removal capabilities by adding a driver to activate a cleaning mechanism, the explosion-proof nature of intrinsically safe speakers prevents the addition of such drivers. Exposed drivers can easily overheat during extended operation, potentially igniting flammable or explosive gases in the surrounding environment. Therefore, the dust removal process for intrinsically safe speakers is an area that requires improvement. Summary of the Invention

[0004] The purpose of this invention is to provide an intrinsically safe voice speaker with recording function, aiming to solve the problem that intrinsically safe speakers in the prior art do not have automatic dust removal.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intrinsically safe voice speaker with recording function, comprising: a chassis and a control component and a recording component disposed inside the chassis, wherein a speaker body is disposed on the chassis, a sound hole plate is disposed on the speaker body, a dust removal mechanism for cleaning the sound hole plate is disposed on the sound hole plate, and a transmission component is disposed on the speaker body for driving the dust removal mechanism to operate through the vibration of the speaker body.

[0006] In order to enable the intrinsically safe voice speaker with recording function to have a dust removal function, as a preferred embodiment of the present invention, the dust removal mechanism includes brushes disposed on both sides of the sound hole plate, and a turntable connected to the brushes is rotatably connected to the middle of the sound hole plate.

[0007] To enable this intrinsically safe voice speaker with recording function to drive a dust removal structure via the speaker body, in a preferred embodiment of the invention, the transmission assembly includes a sliding rod disposed on the speaker body. The sliding rod slides inside a turntable, and at least two push plates are rotatably connected to the turntable. One side of each push plate contacts the sliding rod. The turntable is equipped with two limiting blocks inside for limiting the angle of the push plates. When a push plate contacts one of the limiting blocks, the axial directions of the push plate and the sliding rod are the same. The other limiting block limits the included angle between the axes of the push plate and the sliding rod to an acute angle.

[0008] In a preferred embodiment of the present invention, the speaker body includes a T-shaped iron, a magnet, a frame, a voice coil, a cone, and a dust cap. The sliding rod is disposed on the dust cap, and the end of the sliding rod away from the dust removal mechanism slides inside the T-shaped iron.

[0009] To ensure the intrinsically safe voice speaker with recording function is dustproof, in a preferred embodiment of the present invention, the speaker body is provided with a dustproof component located on the side of the sound hole plate near the sound hole plate. The dustproof component includes two mutually rotatably connected first and second dustproof plates. Each of the first and second dustproof plates has an inner ring and an outer ring, which are connected by an elastic cloth. The elastic cloth and the connected inner and outer rings are provided with slots for a sliding rod to pass through. The inner ring of the second dustproof plate rotates on the inner ring of the first dustproof plate, and the outer ring of the second dustproof plate rotates on the outer ring of the first dustproof plate. The second dustproof plate is provided with an elastic element that pushes the first dustproof plate to rotate and causes the two slots to be staggered. The second dustproof plate is provided with a push block that can push the second dustproof plate to rotate so that the two slots overlap. The speaker body is provided with a mounting slot for installing the dustproof component.

[0010] In order to enable the intrinsically safe voice speaker with recording function to clean dust from the dustproof plate, as a preferred embodiment of the present invention, the inner ring of the first dustproof plate is provided with a spiral groove, a rotating cylinder is fixedly connected to one side of the turntable, the inner ring of the first dustproof plate rotates on the rotating cylinder, the rotating cylinder is provided with a protrusion that slides inside the spiral groove, and both sides of the spiral groove are provided with recesses for the protrusion to pass through.

[0011] In order to enable the intrinsically safe voice speaker with recording function to remove dust, as a preferred embodiment of the present invention, the frame is provided with a dust removal groove located between the sound hole plate and the dustproof component, the dust removal groove is located below the frame, and a dust baffle is provided on the dust removal groove.

[0012] In order to make the intrinsically safe voice speaker with recording function easier to push the plate, as a preferred embodiment of the present invention, a rubber sleeve is provided on the end of the sliding rod that contacts the push plate, and an edge is provided on the side of the push plate that contacts the rubber sleeve.

[0013] As a preferred embodiment of the present invention, the elastic element is a compression spring.

[0014] As a preferred embodiment of the present invention, the chassis is provided with a handle and a control panel.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This intrinsically safe voice speaker with recording function operates the transmission component through the vibration of the speaker body itself. The transmission component moves the dust cleaning mechanism, which cleans the sound control board. This eliminates the need for an external drive to operate the dust cleaning mechanism, thus solving the problem of intrinsically safe speakers not having automatic dust cleaning. At the same time, the dust cleaning mechanism is driven by the vibration of the speaker body itself, making it more energy-efficient during dust cleaning.

[0017] 2. This intrinsically safe voice speaker with recording function can prevent dust from entering the speaker cone by setting a dustproof component inside the speaker body, thereby avoiding the problem of poor sound quality caused by excessive dust. By rotating the protrusion and cooperating with the spiral groove, the inner ring can be moved. When the protrusion rotates to the slot, the elasticity of the elastic cloth can knock off the dust adhering to the elastic cloth, thereby cleaning the dust on the elastic cloth.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 3-5 The present invention provides the following technical solution: an intrinsically safe voice speaker with recording function, comprising: a chassis 1 and a control component 2 and a recording component 3 disposed inside the chassis 1, a speaker body 4 disposed on the chassis 1, a sound hole plate 5 disposed on the speaker body 4, a dust removal mechanism 6 disposed on the sound hole plate 5 for cleaning the dust, and a transmission component 7 disposed on the speaker body 4 to drive the dust removal mechanism 6 to operate through the vibration of the speaker body 4.

[0032] In a specific embodiment of the present invention, the transmission component 7 is operated by the vibration of the speaker body 4 itself, and the dust cleaning mechanism 6 is moved by the transmission component 7, so that the dust cleaning mechanism 6 cleans the sound control board 5. This allows the device to avoid the need for an external drive device to drive the dust cleaning mechanism 6, thereby solving the problem that intrinsically safe speakers do not have automatic dust cleaning. At the same time, the dust cleaning mechanism 6 is driven by the vibration of the speaker body 4 itself, which makes the dust cleaning mechanism 6 more energy-efficient when performing dust cleaning.

[0033] For details, please refer to Figure 9 The dust removal mechanism 6 includes brushes 61 arranged on both sides of the sound hole plate 5. The bristles of the brushes 61 are in contact with the sound hole plate 5. A turntable 62 connected to the brushes 61 is rotatably connected to the middle of the sound hole plate 5. The rotation of the turntable 62 can drive the brushes 61 to rotate, thereby cleaning the dust on the sound hole plate 5.

[0034] For details, please refer to Figure 9 The transmission assembly 7 includes a sliding rod 71 mounted on the horn body 4. The sliding rod 71 slides inside the turntable 62. At least two push plates 72 are rotatably connected to the turntable 62. One side of each push plate 72 contacts the sliding rod 71. The turntable 62 has two limiting blocks 73 inside for angularly limiting the push plates 72. When the push plate 72 contacts one of the limiting blocks 73, the axial directions of the push plate 72 and the sliding rod 71 are the same. The other limiting block 73 limits the angle between the axes of the push plate 72 and the sliding rod 71 to an acute angle. When the sliding rod 71 slides relative to the turntable 62... When the sliding rod 71 moves towards the rotation axis of the push plate 72, it pushes the push plate 72 to form a certain angle, and is then limited by the limiting block 73. The sliding rod 71 continues to move, and through the tilt angle of the push plate 72, it can push the turntable 62 to rotate. When the sliding rod 71 moves back, it causes the angle of the push plate 72 to change, so that the angle of the push plate 72 is parallel to the axis of the sliding rod 71. Therefore, when the sliding rod 71 moves back, it will not push the turntable 62 to rotate. Thus, the sliding rod 71 reciprocates, thereby causing the turntable 62 to rotate.

[0035] For details, please refer to Figure 6The speaker body 4 includes a T-iron 41, a magnet 42, a frame 43, a voice coil 44, a cone 45, and a dust cap 46. A sliding rod 71 is mounted on the dust cap 46. The sliding rod 71 is made of plastic, which makes it lighter and also provides insulation. The end of the sliding rod 71 away from the dust removal mechanism 6 slides inside the T-iron 41. When the dust cap 46 vibrates, it drives the sliding rod 71 to vibrate. Through the action of the magnet 42 and the voice coil 44, the vibration of the dust cap 46 is also made horizontal, which drives the sliding rod 71 to slide horizontally. By placing the other end of the sliding rod 71 inside the T-iron 41, the movement direction of the sliding rod 71 can be limited.

[0036] For further details, please refer to Figure 7-8 The speaker body 4 is provided with a dustproof component 8 located on the side of the sound hole plate 5 near the sound hole plate 5. The dustproof component 8 is used to protect the speaker body 4 from dust. The dustproof component 8 includes two mutually rotatably connected first dustproof plates 81 and second dustproof plates 82. The first dustproof plates 81 and second dustproof plates 82 are arranged concentrically with equal radii. The first dustproof plates 81 and second dustproof plates 82 each have an inner ring and an outer ring, and the inner ring and outer ring are connected by an elastic cloth 83. The elastic cloth 83 is made of elastic and breathable fabric, which can filter dust while also having a sound insulation effect. The elastic cloth 83 and the connected inner and outer rings are all provided with slots 84 for the sliding rod 71 to pass through. The first dustproof plates 81 and second dustproof plates 82 can be installed on the sliding rod 71 through the slots 84. The inner ring of the second dustproof plate 82 rotates on the inner ring of the first dustproof plate 81, and the outer ring of the second dustproof plate 82 rotates on the outer ring of the first dustproof plate 81. The second dustproof plate 82 is provided with An elastic element 85 is used to rotate the first dustproof plate 81 and offset the two slots 84. When the two slots 84 are offset, the sealing performance of the dustproof component 8 is improved, preventing dust from entering the interior of the speaker body through the slots 84. The second dustproof plate 82 is provided with a push block 86 that can push the second dustproof plate 82 to rotate so that the two slots 84 overlap. When the two slots 84 overlap, the dustproof component 8 is mounted on the sliding rod 71 through the slots 84. The speaker body 4 is provided with a part for mounting the dustproof component. When the dustproof component 8 needs to be installed in the mounting slot 9 of component 8, the elastic element 85 is first compressed by the push block 86, so that the two slots 84 overlap. Then, the dustproof component 8 is placed inside the mounting slot 9, so that the first dustproof plate 81, the second dustproof plate 82 and the sliding rod 71 are coaxial. Then, the push block 86 is released, and the two slots 84 are staggered by the action of the elastic element 85, which can improve the sealing of the dustproof component 8. When the dustproof component 8 needs to be disassembled, the above steps can be performed in the same direction.

[0037] For further details, please refer to Figure 7-8The inner ring of the first dustproof plate 81 has a spiral groove 811. A rotating cylinder 812 is fixedly connected to one side of the turntable 62. The inner ring of the first dustproof plate 81 rotates on the rotating cylinder 812. The rotating cylinder 812 is provided with a protrusion 813 that slides inside the spiral groove 811. Both sides of the spiral groove 811 are provided with recesses 814 for the protrusion 813 to pass through. By rotating the protrusion 813 and cooperating with the spiral groove 811, the inner ring can be moved. When the protrusion 813 rotates to the groove 84, the elasticity of the elastic cloth 83 can knock off the dust adhering to the elastic cloth 83, thereby cleaning the dust on the elastic cloth.

[0038] For further details, please refer to Figure 5-6 The basin frame 43 has a dust discharge trough 431 located between the sound hole plate 5 and the dustproof component 8. The dust discharge trough 431 is located below the basin frame 43. A dust baffle 432 is provided on the dust discharge trough 431. The dust that falls off during cleaning will fall below the basin frame 43. By opening the dust baffle 432, the dust can be cleaned.

[0039] For further details, please refer to Figure 10 A rubber sleeve 10 is provided on the end of the sliding rod 71 that contacts the push plate 72, and an edge 11 is provided on the side of the push plate 72 that contacts the rubber sleeve 10.

[0040] Preferably, the elastic element 85 is a compression spring.

[0041] Furthermore, the chassis 1 is equipped with a handle 12 and a control panel 13.
