Description

Technical Field

[0001] The present invention relates to the field of speaker design, and more particularly, to a speaker-mounted device based on a monitoring and maintenance component. Background Art

[0002] A speaker-mounted device refers to an electronic device that is connected or integrated with a speaker and is used to provide audio signals, control functions, or other additional functions. These devices can be independent hardware devices or modules integrated inside the speaker. Monitoring and maintenance means for speaker-mounted devices are the key to ensuring their long-term stable operation and optimized performance.

[0003] Common hardware temperature monitoring and maintenance means inside a speaker-mounted device rely on real-time monitoring of the temperature inside the speaker. When the temperature exceeds a preset threshold, a heat dissipation mechanism (such as a fan startup) is triggered, or the output power is reduced, or in the case of continuously high temperatures, the system automatically shuts down the speaker to avoid permanent damage. However, such measures are difficult to cope with sudden fires or high-pressure situations, which may lead to permanent damage to the device or even cause safety accidents.

[0004] Therefore, there is an urgent need to design a speaker-mounted device based on a monitoring and maintenance component that has a fire extinguishing mechanism. Summary of the Invention

[0005] In order to overcome the shortcomings of the above-mentioned prior art that are difficult to cope with sudden fires or high-pressure situations, the purpose of the present invention is to provide a speaker-mounted device based on a monitoring and maintenance component that has a fire extinguishing mechanism.

[0006] A speaker-mounted device based on a monitoring and maintenance component, comprising a speaker body. A terminal board is installed at the rear end of the outer part of the speaker body. A number of symmetric heat dissipation openings are provided at the lower part of the inner rear wall of the speaker body. An electric fan is installed at the inner bottom of the speaker body near the heat dissipation openings. A high and low frequency sound generation module is embedded in the front part of the speaker body. The wiring board of the high and low frequency sound generation module is installed on one side of the outer part of the speaker body. A bearing seat is fixed in the middle of the speaker body. A frequency division control template is installed at the bottom of the bearing seat. The output wire of the frequency division control template passes through the inner wall of the speaker body and is connected to the wiring board. A guide frame is arranged on one side of the middle of the bearing seat. A comprehensive temperature and pressure sensor is installed at the center of the bottom of the bearing seat. A monitoring alarm connected by wire to the comprehensive temperature and pressure sensor is installed on the top of the speaker body. A carbon dioxide fire extinguisher tank is installed on the other side of the middle of the bearing seat. A three-way delivery pipe in a bent shape is connected to the output port of the carbon dioxide fire extinguisher tank. The bent part of the three-way delivery pipe extends into the lower part of the speaker body. Four spray nozzles are respectively connected to the outer part of the three-way delivery pipe. Two of the spray nozzles of the three-way delivery pipe penetrate through both sides inside the bearing seat and are arranged vertically in opposite directions. A movable seat close to the carbon dioxide fire extinguisher tank is slidably arranged on the guide frame. An articulated part is arranged at one end of the movable seat close to the carbon dioxide fire extinguisher tank. A blocking block is articulated at the end of the articulated part. The blocking block is slidably connected to the three-way delivery pipe and the output port of the carbon dioxide fire extinguisher tank. A metal elastic sheet is arranged on the lower side of the middle of the bearing seat. The metal elastic sheet is in contact with the movable seat. Springs are symmetrically arranged between the movable seat and the guide frame.

[0007] In one embodiment, it further includes a sealing plate and a lifting member. A sealing plate is slidably arranged on the inner rear wall surface of the speaker body. A through groove corresponding to the heat dissipation opening is opened on the sealing plate. A lifting member in an inclined shape is rotatably and slidably arranged at the end of the movable seat away from the articulated part. One end of the lifting member close to the inner rear wall surface of the speaker body is articulated to the upper end of the sealing plate.

[0008] In one embodiment, it further includes an inhalation tube, diaphragm 1, diaphragm 2, mating part, docking part, wedge block, guide ring, spring 2, spring 3, and adjustment ring. Symmetric inhalation tubes are embedded in the inner rear wall surface of the speaker body. Two closely contacting diaphragm 1 and diaphragm 2 are slidably arranged in the inhalation tube. Through holes are provided on diaphragm 1 and diaphragm 2, and the through holes of the two are staggered from each other. A mating part is arranged at the upper end of diaphragm 2 away from diaphragm 1. A number of card slots are circumferentially provided on the outer surface of the mating part. A docking part is arranged on the inner upper wall of the inhalation tube near its discharge port. A guide ring is arranged on the inner upper wall of the inhalation tube outside the docking part. The outer wall of the docking part is in sliding contact with the inner wall of the guide ring. A number of wedge blocks that fit with the card slots are slidably arranged in the docking part. The ends of a number of wedge blocks are provided with inclined blocks. The inner wall of the mating part is in sliding contact with the outer wall of the docking part. A spring 2 is arranged between the wedge block and the docking part. A spring 3 is arranged between the guide ring and diaphragm 2. An adjustment ring is threadedly arranged on one side of the docking part near the discharge port of the inhalation tube. The adjustment ring is in rotational contact with the inclined block of the wedge block. When in contact, the wedge block slides towards the inside of the docking part.

[0009] In one embodiment, it further includes an airbag and a one-way valve. An airbag is installed at the rear wall surface outside the speaker body corresponding to the discharge port of the inhalation tube, and a one-way valve is installed at the docking part between the airbag and the discharge port.

[0010] In one embodiment, the installation part of the airbag and the one-way valve with the speaker body is a detachable structure.

[0011] In one embodiment, an installation groove is provided on one side of the lower part of the bearing seat near the high and low frequency sound generating module.

[0012] In one embodiment, it further includes a pull plate, a stable seat, a top plate, a baffle group, and a spring 4. A pull plate is arranged on one side of the moving seat near the three-way delivery pipe. The bottom of the pull plate is slidably connected to the bottom surface of the middle part inside the bearing seat. Stable seats are symmetrically arranged on the bottom surface of the middle part inside the bearing seat. The end of the pull plate is slidably connected to the stable seat. One end of the pull plate facing the high and low frequency sound generating module is connected to a top plate. A baffle group is slidably arranged in the installation groove of the bearing seat. The baffle group is composed of a number of horizontally stacked plates that slide. A fitting groove is provided on one of the plates in the baffle group close to the top plate. The end of the top plate is close to and inserted into the fitting groove to form a fixation. When the top plate disengages from the fitting groove, the baffle group slides down one by one due to its own weight to unfold and block the lower part of the high and low frequency sound generating module. A spring 4 is arranged between the stable seat and the pull plate.

[0013] In one embodiment, it further includes a protective cover and a torsion spring. A protective cover for covering the airbag is hinged on the rear wall surface outside the speaker body, and torsion springs are symmetrically arranged at the hinge part between the protective cover and the outside of the speaker body.

[0014] The beneficial effects are: 1. The present invention triggers the carbon dioxide fire extinguishing tank due to thermal expansion of the metal shrapnel, and the fire extinguishing gas quickly covers the entire interior of the speaker, effectively extinguishing possible fire sources and ensuring the safety of the equipment and the surrounding environment; the monitoring alarm sounds an alarm and triggers the start of the electric fan to avoid permanent damage caused by overheating or overpressure, thereby extending the service life of the equipment.

[0015] 2. When the movable seat slides upward, the lifting member is driven to rotate, so that the sealing plate is driven to slide upward, the sealing plate is misaligned with the heat dissipation port, the heat dissipation port is closed, and the fire extinguishing gas is prevented from leaking from the heat dissipation port.

[0016] 3. The present invention realizes effective regulation of internal pressure through the coordinated work of diaphragm 1, diaphragm 2, matching parts and docking parts; by removing the airbag and rotating the adjustment ring to unlock the delivery channel, it ensures that the system can safely release pressure under high pressure to prevent the occurrence of dangerous situations such as explosions.

[0017] 4. When the movable seat of the present invention slides up, the pull plate moves accordingly, and the top plate gradually separates from the matching groove in the baffle group. The baffle groups slide down and unfold one by one to form a physical barrier to prevent the fire extinguishing gas from directly impacting the high and low frequency sound modules, protecting them from damage and ensuring that the audio output quality is not affected.

DETAILED DESCRIPTION

[0036] To make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0037] Example: A speaker-mounted device based on a monitoring and maintenance component, such as Figures 1-8 , Figure 13 , Figure 16 and Figure 17As shown in the figure, it includes a speaker body 1. The speaker body 1 serves as the housing of the entire device, protecting the internal components and providing a foundation for installing and fixing other components. The speaker body 1 fixes each internal component inside it through mechanical structures such as screws and buckles. At the rear end of the outside of the speaker body 1, a terminal board 10 is installed. The terminal board 10 is used for external audio signal input and power connection to ensure that the speaker can receive audio signals and be powered. At the lower part of the rear inner wall of the speaker body 1, a number of symmetric heat dissipation openings 11 are provided. The heat dissipation openings 11 allow air to circulate, helping to dissipate heat inside the speaker body 1 and preventing overheating. An electric fan 12 is installed at the inner bottom of the speaker body 1 near the heat dissipation openings 11. An embedded high and low sound generating module 2 is installed at the front part inside the speaker body 1, responsible for generating high and low sounds to achieve audio output. The wiring board 20 of the high and low sound generating module 2 is installed on one side of the outside of the speaker body 1. A bearing seat 3 is fixed in the middle of the speaker body 1, serving as the main support platform for internal components, fixing and organizing the positions of each module. An installation groove is provided on one side of the lower part of the bearing seat 3 near the high and low sound generating module 2. A frequency division control template 30 is installed at the bottom of the bearing seat 3. The frequency division control template 30 distributes audio signals to the high and low sound generating module 2 according to the frequency range to ensure sound quality. The output line 31 of the frequency division control template 30 passes through the inner wall of the speaker body 1 and is connected to the wiring board 20. A guiding frame 32 is provided on one side in the middle of the bearing seat 3. A comprehensive temperature and pressure sensor 4 is installed at the center of the bottom of the bearing seat 3. The comprehensive temperature and pressure sensor 4 monitors the temperature and pressure changes inside the speaker body 1 in real time and triggers corresponding protection measures. A monitoring alarm 40 electrically connected to the comprehensive temperature and pressure sensor 4 is installed on the top of the speaker body 1. When the comprehensive temperature and pressure sensor 4 monitors that the temperature or pressure exceeds the preset threshold, the monitoring alarm 40 emits an alarm and transmits a signal to the main control system. A carbon dioxide fire extinguisher tank 41 is installed on the other side in the middle of the bearing seat 3, automatically releasing fire extinguishing gas when detecting high temperature to quickly extinguish possible fire sources. The output port of the carbon dioxide fire extinguisher tank 41 is connected to a bent three-way delivery pipe 42. The bent part of the three-way delivery pipe 42 extends into the lower part inside the speaker body 1 and is fixed through a pipe joint. Four spray nozzles 43 are respectively connected to the outside of the three-way delivery pipe 42. Two of the spray nozzles 43 of the three-way delivery pipe 42 penetrate through both sides inside the bearing seat 3 and are arranged vertically in opposite directions. The three-way delivery pipe 42 guides the fire extinguishing gas from the carbon dioxide fire extinguisher tank 41 to the four spray nozzles 43 to ensure that the fire extinguishing gas can evenly cover the internal space of the speaker. A movable seat 44 similar to the carbon dioxide fire extinguisher tank 41 is slidably arranged on the guiding frame 32. One end of the movable seat 44 close to the carbon dioxide fire extinguisher tank 41 is provided with a hinge part 441 through a mechanical hinge. A blocking block 45 is hinged to the end of the hinge part 441. The blocking block 45 blocks the output port of the carbon dioxide fire extinguisher tank 41 in the normal state to prevent gas leakage. The blocking block 45 is slidably connected to the three-way delivery pipe 42 and the output port of the carbon dioxide fire extinguisher tank 41. The hinge part 441 rotates with the movable seat 44, driving the blocking block 45 to move away and open the output port of the carbon dioxide fire extinguisher tank 41.A metal shrapnel 46 is arranged on the lower side near the middle inside the bearing seat 3. The metal shrapnel 46 is a key component for temperature sensing. The metal shrapnel 46 is in contact fit with the moving seat 44. The metal shrapnel 46 pushes up the moving seat 44 due to thermal expansion, triggering the fire extinguishing mechanism. Springs 47 are symmetrically arranged between the moving seat 44 and the guide frame 32 to maintain the stability of the moving seat 44 in the initial position and be smoothly released when triggered, driving the moving seat 44 to return to its original position.

[0038] As Figure 7 shown, it further includes a sealing plate 5 and a lifting member 50. The sealing plate 5 is slidably arranged on the inner rear wall surface of the speaker body 1. A through groove corresponding to the heat dissipation opening 11 is opened on the sealing plate 5. The lifting member 50, which is inclined, is rotatably and slidably arranged on the moving seat 44 away from the hinge member 441. One end of the lifting member 50 close to the inner rear wall surface of the speaker body 1 is hinged to the upper end of the sealing plate 5. When the lifting member 50 slides up with the moving seat 44, it drives the sealing plate 5 to slide up, closing the heat dissipation opening 11 to prevent the leakage of the fire extinguishing gas and ensuring the maximization of the fire extinguishing effect.

[0039] As Figures 8-11As shown, it also includes an inhalation tube 6, a first diaphragm 60, a second diaphragm 61, a mating part 612, a docking part 62, a wedge block 63, a guide ring 64, a second spring 65, a third spring 66 and an adjustment ring 67. Symmetric inhalation tubes 6 are embedded in the inner rear wall surface of the speaker body 1. Two closely contacting first diaphragm 60 and second diaphragm 61 are slidably arranged in the inhalation tube 6. Through holes 611 are provided on the first diaphragm 60 and the second diaphragm 61, and the through holes 611 of the two are staggered from each other to control the gas flow through the through holes 611. A mating part 612 is arranged at the upper end of the second diaphragm 61 away from the first diaphragm 60. A plurality of card slots are circumferentially provided on the outer surface of the mating part 612. A docking part 62 is arranged on the inner upper wall of the inhalation tube 6 near its discharge port. A guide ring 64 is arranged on the inner upper wall of the inhalation tube 6 outside the docking part 62. The outer wall of the docking part 62 is in sliding contact with the inner wall of the guide ring 64. A plurality of wedge blocks 63 that fit with the card slots are slidably arranged in the docking part 62. The ends of the plurality of wedge blocks 63 are all provided with inclined blocks. The inner wall of the mating part 612 is in sliding contact with the outer wall of the docking part 62. A second spring 65 is arranged between the wedge block 63 and the docking part 62. The mating part 612 and the docking part 62 are docked to lock the conveying channel. Through the wedge block 63 fitting with the card slot, it is controlled by the second spring 65. A third spring 66 is arranged between the guide ring 64 and the second diaphragm 61 to ensure that the first diaphragm 60 and the second diaphragm 61 can be reset. An adjustment ring 67 is threadedly arranged on one side of the docking part 62 close to the discharge port of the inhalation tube 6. The operation of the adjustment ring 67 needs to be simple and easy to ensure that users can conveniently carry out maintenance and adjustment. The adjustment ring 67 is in rotational contact with the inclined block of the wedge block 63. When contacting, the wedge block 63 slides into the interior of the docking part 62. By rotating and contacting the inclined block of the wedge block 63, the docking between the connecting part 612 and the docking part 62 is unlocked. The above together constitute a pressure adjustment mechanism to ensure that the internal pressure is effectively managed and can be safely relieved when needed.

[0040] As Figure 8 and Figure 12 shown, it also includes an airbag 68 and a one-way valve 69. An airbag 68 is installed at the rear wall surface outside the speaker body 1 corresponding to the discharge port of the inhalation tube 6. A one-way valve 69 is installed at the docking part of the airbag 68 and the discharge port. When rapid exhaust is needed, the gas enters the airbag 68 through the one-way valve 69 to reduce the internal pressure. The installation parts of the airbag 68 and the one-way valve 69 with the speaker body 1 are of a detachable structure for convenient maintenance.

[0041] As Figure 2 and Figures 13-15As shown in the figure, it further includes a pull plate 7, a stable seat 70, a top plate 71, a baffle group 72 and a fourth spring 73. A pull plate 7 is arranged on the side of the moving seat 44 close to the three-way conveying pipe 42. The bottom of the pull plate 7 is slidably connected to the bottom surface in the middle of the bearing seat 3. Stable seats 70 are symmetrically arranged on the bottom surface in the middle of the bearing seat 3. The end of the pull plate 7 is slidably connected to the stable seat 70. One end of the pull plate 7 facing the high and low tone sound generating module 2 is connected with a top plate 71. A baffle group 72 is slidably arranged in the installation groove of the bearing seat 3. The baffle group 72 is composed of several horizontally stacked plates that slide. A fitting groove is formed in one of the plates of the baffle group 72 close to the top plate 71. The end of the top plate 71 is close to and inserted into the fitting groove to form a fixation. When the top plate 71 is disengaged from the fitting groove, the baffle group 72 slides down one by one due to its own weight to unfold and shield the lower part of the high and low tone sound generating module 2 to prevent the fire extinguishing gas from directly impacting the high and low tone sound generating module 2. A fourth spring 73 is arranged between the stable seat 70 and the pull plate 7, and the fourth spring 73 can ensure the smooth movement of the pull plate 7.

[0042] As Figure 1 , Figure 16 and Figure 17 As shown in the figure, it further includes a protective cover 8 and a torsion spring 80. A protective cover 8 for covering the airbag 68 is hinged to the rear wall surface outside the speaker body 1. The protective cover 8 protects the airbag 68 from the outside under normal circumstances. Torsion springs 80 are symmetrically arranged at the hinge between the protective cover 8 and the outside of the speaker body 1. The protective cover 8 is kept in a closed state through the torsion springs 80. When the airbag 68 is inflated, it pushes open the protective cover 8 for easy observation and maintenance.

[0043] First, place the speaker body 1 in a suitable position and connect the power supply through the terminal board 10. The external audio signal is input into the speaker body 1 through the terminal board 10. The frequency division control template 30 distributes the signal to the high and low frequency sound generating modules 2 according to the frequency range. The integrated temperature and pressure sensor 4 monitors the temperature and pressure changes inside the speaker body 1 in real time. The data of the integrated temperature and pressure sensor 4 is transmitted through wires to the monitoring alarm 40 located at the top of the speaker body 1. When the temperature or pressure exceeds the preset threshold, the monitoring alarm 40 issues an alarm and transmits the signal to the main control system to trigger corresponding protection measures; as the internal temperature rises, the metal elastic sheet 46 arranged at the lower side of the middle part in the bearing seat 3 bends due to thermal expansion. The bent metal elastic sheet 46 pushes up the moving seat 44, causing it to slide upward along the guide frame 32. During the upward sliding process of the moving seat 44, the hinge 441 at one end close to the carbon dioxide fire extinguishing tank 41 rotates accordingly. The rotation of the hinge 441 drives the blocking block 45 to move. The blocking block 45 slides away from the outlets of the three-way delivery pipe 42 and the carbon dioxide fire extinguishing tank 41, opening the passage. The carbon dioxide fire extinguishing tank 41 is triggered, and the extinguishing gas enters the delivery pipe through the three-way delivery pipe 42 and is ejected from the four nozzles 43, covering the entire inside of the speaker to quickly extinguish the possible fire source; during the upward sliding process of the moving seat 44, the lifting member 50 is driven to rotate, causing the sealing plate 5 to be driven upward. The sealing plate 5 is then misaligned with the heat dissipation port 11, thus covering the heat dissipation port 11, thereby closing the heat dissipation port 11 to prevent the extinguishing gas from leaking from the heat dissipation port 11 and ensuring the maximization of the fire extinguishing effect; in addition, when the internal pressure changes, the diaphragm one 60 and the diaphragm two 61 slide relative to each other under the action of the pressure difference. The diaphragm two 61 is gradually pushed towards the outlet of the suction pipe 6, causing the diaphragm one 60 and the diaphragm two 61 to no longer be in close contact. At this time, the gas passes through the through holes 611 of both of them. At the same time, the mating member 612 moves together with the diaphragm two 61 and gradually approaches the docking member 62. When the diaphragm two 61 is about to reach the outlet, the mating member 612 forms a docking with the docking member 62, locking the already opened delivery channel. During the docking process of the mating member 612 and the docking member 62, the wedge block 63 slides inward under the action of the spring two 65 and then is pushed back to its original position by the spring two 65 and snaps into the card slot on the mating member 612 to ensure that the delivery channel remains open. When the diaphragm two 61 reaches the outlet, the gas enters the airbag 68 through the one-way valve 69 to achieve rapid exhaust and reduce the internal pressure; when pressure relief is required, the airbag 68 can be disassembled and the adjustment ring 67 can be rotated to contact the inclined block of the wedge block 63, forcing the wedge block 63 to slide inward into the docking member 62, unlocking the connection between the mating member 612 and the docking member 62. At this time, the diaphragm one 60 and the diaphragm two 61 can return to their original positions under the action of the spring three 66 to re-close the channel;When the moving seat 44 slides upward, the pull plate 7 also moves accordingly. The top plate 71 gradually disengages from the mating groove in the baffle plate group 72 along with the pull plate 7. Under the action of its own weight, the plates on the baffle plate group 72 slide down one by one and unfold to cover the space below the high and low sound generating module 2, forming a physical barrier to prevent the fire extinguishing gas from directly impacting the high and low sound generating module 2 and protecting it from damage.

[0044] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes can be made therein without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
