Description

Technical Field

[0001] The present invention belongs to the technical field of speaker boxes, and in particular relates to a speaker box with a storage function. Background Art

[0002] A speaker is a device that converts electrical signals into sound signals and is the terminal of the entire audio system. It is usually composed of speakers, cabinets, circuits and other parts. Its working principle is to amplify the audio signal through the circuit part, and then the speaker converts the electrical signal into a sound signal. The cabinet plays the role of protecting internal components, sound reflection and sound effect adjustment. Speakers are widely used in homes, businesses and public places. They can be divided into active speakers and passive speakers. They can also be classified according to usage scenarios, playback frequency, purpose, cabinet structure, number of speaker units and cabinet material.

[0004] After the speaker is used, the wiring harness connected to it for playing audio needs to be stored and organized. However, this process is greatly interfered with by external factors. For example, during the storage of the speaker wiring harness, if the wiring harness is bent too much, it is easy to cause damage to the conductive core in the wiring harness. Secondly, in a low temperature environment, the hardness of the wiring harness material increases. At this time, if the bending degree of the wiring harness is slightly too large, the wiring harness is prone to damage. This not only affects the reliability of the speaker when used again, but also affects the life and effect of the speaker wiring harness. In addition, manual storage of the wiring harness is cumbersome and inconvenient, and the staff have to clean the stains attached to the surface of the wiring harness, which greatly affects the convenience of using the speaker.

[0019] Compared with existing technologies, the advantages of a speaker with storage function are:

[0020] Through the automatic storage mechanism, wire harness surface cleaning mechanism and air supply mechanism, when the speaker needs to store the wire harness after use, first unplug the side end plug of the wire harness away from the speaker body, and send an electrical signal to the PLC controller by touching the control panel. After receiving the electrical signal, the PLC controller controls the automatic storage mechanism, wire harness surface cleaning mechanism and air supply mechanism to work. The air supply mechanism delivers clean hot air to the wire harness surface cleaning mechanism, and the storage mechanism itself can drive multiple storage and reeling wheels to automatically reel in multiple wire harnesses. While the wire harness is being reeled in, the high-speed hot air ejected by the wire harness surface cleaning mechanism can blow clean and dry the wire harness surface, without the need for manual cleaning of the wire harness surface. The attached dust or water stains, and in a low temperature environment, the hot air flow ejected from the hollow tube can also increase the surface temperature of the wire harness, thereby increasing the softness and toughness of the wire harness in a low temperature environment by increasing the surface temperature of the wire harness, and avoiding the hardened wire harness from being damaged due to a slightly larger bending angle during the storage process in a low temperature environment. This mechanism enables the speaker to not only have the function of automatic blowing, cleaning, drying and storage of the wire harness, but also has the ability to increase the surface temperature of the wire harness, and improve the softness and toughness of the wire harness in a low temperature environment, thereby improving the safety of the wire harness storage in a low temperature environment, which not only guarantees the life and effect of the speaker harness, but also guarantees the reliability of the speaker.

[0021] Through the set wire harness detection mechanism, after the wire harness is stored, the staff controls the operation of the wire harness detection mechanism by touching the control panel and the PLC controller. Specifically, the power board is electrically connected to one detection end of the electronic ohmmeter through a wire, and the other detection end of the electronic ohmmeter is electrically connected to multiple detection conductive branches. The multiple detection conductive branches are electrically connected to the wire harnesses on the multiple storage and reel wheels in sequence, and the indicator light is placed closest to the wire harness to be detected. At the same time, the conductive connector and micro relay near the indicator light are also components of the detection conductive branch of the wire harness to be detected. Then the PLC controller controls multiple detection conductive branches in sequence at intervals of 30 seconds to detect the wire harness corresponding to the detection conductive branch. If the detection wire harness is unqualified, the alarm speaker is controlled to alarm and remind the staff to replace the wire harness immediately. When this mechanism is used, the speaker has the function of wire harness detection to avoid damage to the speaker wire harness and affect the quality and reliability of the speaker audio playback.

[0022] Through the air supply mechanism and temperature sensor, when the speaker is in normal use, the temperature sensor also detects the temperature inside the speaker body, and the temperature sensor converts the temperature value into an electrical signal and sends it to the PLC controller. If the internal temperature of the speaker body exceeds the warning temperature preset by the PLC controller due to the high temperature environment or overload operation, the PLC controller promptly controls the operation of the air pump, and the air pump sucks the outside air into the interior of the speaker body, accelerating the air flow inside the speaker body. The injected air carries the heat and is quickly discharged from the heat dissipation holes of the speaker body itself. The heat dissipation is accelerated by the flowing air to avoid the speaker operation being affected by high temperature, thereby ensuring that the speaker can continue to work reliably. This mechanism enables the speaker to have the function of active heat dissipation and improves the reliability of the speaker. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] A wire harness surface cleaning mechanism 6 is fixedly embedded in the bottom wall of the storage bin 2. The wire harness surface cleaning mechanism 6 includes an L-shaped hollow block 61 fixedly embedded in the bottom end of the storage bin 2. The top of the horizontal part of the L-shaped hollow block 61 is fixedly connected to a plurality of hollow cylinders 62. The number of the hollow cylinders 62 is consistent with the number of the storage and winding wheels 56. The inner wall of the hollow cylinder 62 is provided with a plurality of air outlet holes 63.

[0036] The outer wall of the speaker body 1 is fixedly connected to a connecting cover 11, and the inner wall of the connecting cover 11 is fixedly connected to an air supply mechanism 8. The air supply mechanism 8 includes an air pump 81 fixedly connected to the inner wall of the connecting cover 11, and the air inlet end of the air pump 81 is fixedly connected to a filter assembly 9. The filter assembly 9 includes an air guide cylinder 91 fixedly connected to the air inlet end of the air pump 81. The air inlet end of the air guide cylinder 91 passes through the outer wall of the connecting cover 11, and the inner wall of the air guide cylinder 91 is sealed and movably connected with an insert ring 92.

The material of the second air pipe 84 is fluororubber, and the metal mesh 14 expands the heat conduction area of ​​the electric heating pipe 85, thereby improving the effect of the electric heating pipe 85 in raising the air temperature.

This mechanism can not only realize automatic blowing, cleaning, drying and resistance to low temperature interference on the wiring harness surface, but also enable the speaker to have the function of active heat dissipation, thereby ensuring that the speaker can be used continuously and reliably.

[0037] The top wall of the storage bin 2 is fixedly connected to a wiring harness detection mechanism 7, which includes an insulating plate 71 fixedly connected to the top wall of the storage bin 2, and a plurality of micro relays 72, indicator lights 73 and conductive connectors 74 are fixedly connected to the lower surface of the insulating plate 71, and the tops of the plurality of conductive connectors 74 are electrically connected to a power board 75. The number of micro relays 72, indicator lights 73 and conductive connectors 74 is consistent with the number of winding wheels. The outer wall of the speaker body 1 located inside the connecting cover 11 is fixedly connected to an electronic ohmmeter 76, and the outer wall of the connecting cover 11 is fixedly connected to an alarm speaker 77. The outer wall of the bottom end of the wire tube 10 is provided with a plurality of circular wire holes 78. When this mechanism is used, the speaker has the function of wiring harness detection to avoid damage to the speaker wiring harness and affect the quality and reliability of the speaker audio playback.

[0038] The inner wall of the connecting cover 11 is fixedly connected with a PLC controller 12 and a backup lithium battery 13, and the four corners of the lower surface of the speaker body 1 are fixedly connected with universal wheels 15. A mounting hole is provided at the top of the speaker body 1, and a touch control panel 16 is fixedly connected to the hole wall of the mounting hole. The touch control panel 16 can improve the convenience of speaker operation.

[0039] The electronic ohmmeter 76, the temperature sensor 86 and the touch control panel 16 are all electrically connected to the input end of the PLC controller 12 through wires, and the alarm speaker 77, the vacuum pump 81, the three-way reversing solenoid valve 82 and the electric heating tube 85 are all electrically connected to the output end of the PLC controller 12 through wires. The electronic ohmmeter 76 has a communication interface and an analog signal conversion module, which can convert the resistance value into a model electrical signal and transmit it to the PLC controller 12 through the analog signal conversion module. The power-on equipment and electrical connections in the present invention are all existing technologies and will not be repeated here.

[0040] The operating principle of the present invention is now described as follows: when the speaker is in use, the multiple interfaces of the speaker body 1 connecting the wire harness are electrically connected to the conductive hollow blocks 57 in each storage and reel 56 in sequence through wires, multi-channel conductive slip rings 55 and multiple L-shaped conductive rods 510, and the side end conductive core of the wire harness is inserted into the wire hole 58. Then, the fixing bolt 59 is rotated to squeeze the side end of the wire harness conductive core to achieve stable electrical contact between the side end of the wire harness conductive core and the conductive hollow block 57, thereby ensuring that the wire harness can be reliably connected to the speaker body 1. After that, the side end plug of the wire harness away from the storage and reel 56 passes through the hollow cylinder 62 and is finally connected to other devices in the sound reinforcement system. The hollow cylinder 62 can also limit the multiple wire harnesses to avoid the situation where multiple wire harnesses are tangled.

[0041] When the speaker is finished using and the wiring harness needs to be stored, first unplug the wiring harness away from the side plug of the speaker body 1, and send an electric signal to the PLC controller 12 by touching the control panel 16. After receiving the electric signal, the PLC controller 12 controls the motor 53, the electric heating tube 85, the air pump 81 and the three-way reversing solenoid valve 82 to energize and work. After the air pump 81 is energized, clean air is sucked into the energized three-way reversing solenoid valve 82 through the filter component 9. The energized three-way reversing solenoid valve 82 guides the clean air into the second air pipe 84. After the electric heating tube 85 is energized, it can increase the temperature in the second air pipe 84 and form a high-temperature environment. After the clean air is introduced into the second air pipe 84, it is affected by the high-temperature environment and the temperature is increased, forming 5 The hot air of 0℃-60℃ finally passes through the L-shaped hollow block 61 and enters the multiple hollow cylinders 62. Then, due to the small aperture of the air outlet 63, the hot air has a high flow rate when it is discharged from the small-aperture air outlet 63. Then, the high-speed hot air can be blown, cleaned and dried on the surface of the wire harness inside the hollow cylinder 62, without the need to manually clean the dust or water stains attached to the surface of the wire harness. In a low temperature environment, the hot air flow ejected from the hollow cylinder 62 can also increase the surface temperature of the wire harness, thereby increasing the softness and toughness of the wire harness in a low-temperature environment and avoiding the damage of the hardened wire harness due to a slightly large bending angle during the storage process in a low-temperature environment.

[0042] After the motor 53 is energized, it can drive the rotating drum 52 to rotate, and the rotating drum 52 drives the storage and reeling wheel 56 to rotate, and the storage and reeling wheel 56 drives the wire harness connected to the conductive hollow block 57 to automatically retract. While retracting, the hot air flow ejected by the wire harness surface cleaning mechanism 6 can fully clean and dry the wire harness, and can soften the surface of the wire harness to ensure the safety of the wire harness storage. When paying out the wire in a low temperature environment, it can also control the vacuum pump 81, the three-way reversing solenoid valve 82 and the electric heating tube 85 to be energized. At this time, the electric heating tube 85 The heated air can increase the temperature of the storage compartment 2 and the temperature of the wire harness wound on the storage reel 56, softening the wire harness material and improving the safety and convenience of wire harness payout. This mechanism not only enables the speaker to automatically clean, dry and store the wire harness, but also increases the surface temperature of the wire harness and improves the softness and toughness of the wire harness in low-temperature environments, thereby improving the safety of wire harness storage in low-temperature environments, ensuring not only the life and effectiveness of the speaker harness, but also the reliability of the speaker.

[0043] After the wiring harness is stored, the staff not only controls the motor 53, the electric heating tube 85, the air pump 81 and the three-way reversing solenoid valve 82 to be powered off by touching the control panel 16 and the PLC controller 12, but also controls the wiring harness detection mechanism 7 to work. Specifically, the power board 75 is electrically connected to one detection end of the electronic ohmmeter 76 through a wire, and the other detection end of the electronic ohmmeter 76 is electrically connected to a plurality of detection conductive branches, and the plurality of detection conductive branches are electrically connected to the wiring harnesses on the plurality of storage and reel wheels 56 in sequence (that is, each conductive circuit at the fixed end of the multi-channel conductive slip ring 55 that is conductive to the wiring harness is connected to a detection conductive branch, and the detection conductive branch is connected in series with a micro relay 72, and finally a micro relay is connected in series). The detection conductive branch of the electrical appliance 72 is electrically connected to the detection end of the electronic ohmmeter 76, and the triggering power connection end of the multiple micro relays 72 is not only connected in parallel with an indicator light 73, but the triggering power connection end of the micro relay 72 is also electrically connected to the output end of the PLC controller 12 through a wire). In addition, the indicator light 73 is placed closest to the wiring harness to be detected. At the same time, the conductive connector 74 and the micro relay 72 near the indicator light 73 are also components of the detection conductive branch of the wiring harness to be detected. Then the PLC controller 12 controls the multiple detection conductive branches in turn at intervals of 30 seconds to detect the wiring harness corresponding to the detection conductive branch. The specific process is that after the PLC controller 12 controls the indicator light 73 to light up, the worker The staff immediately inserts the plug on the side of the wiring harness closest to the lighted indicator light 73 into the conductive connector 74 closest to the lighted indicator light 73. At the same time, when the indicator light 73 is lit, the trigger end of the micro-relay 72 of the conductive branch that is detected by the lighted indicator light 73 will be energized, thereby ensuring that the triggered end of the micro-relay 72 is closed and conductive, ensuring that the electronic ohmmeter 76 detects the resistance value of the wiring harness, and the electronic ohmmeter 76 can send the resistance value to the PLC controller 12 in the form of an electrical signal. If the detected resistance value is not within the normal resistance threshold value range preset by the PLC controller 12, it indicates that the conductive core inside the wiring harness is damaged or broken, causing an abnormal change in the resistance value of the wiring harness. Then the PLC controller 12 will turn on the power. The controller 12 controls the alarm speaker 77 to play an alarm message to remind the staff to replace the wiring harness immediately. When replacing the wiring harness, it is only necessary to separate the wiring harness from the storage and reel 56, and remove the conductive core side end of the wiring harness from the conductive hollow block 57, and then replace the new wiring harness. On the contrary, when the detected resistance value meets the normal resistance threshold range preset by the PLC controller 12, it is only necessary to wait for 30 seconds. After the next indicator light 73 is lit, immediately unplug the wiring harness side end plug previously inserted into the conductive connector 74, and repeat the above steps to detect the wiring harness closest to the latest lit indicator light 73. When this mechanism is used, the speaker has the function of wiring harness detection to avoid damage to the speaker wiring harness and affect the quality and reliability of the speaker audio playback;

[0044] When the speaker is in normal use, the temperature sensor 86 also detects the temperature inside the speaker body 1, and the temperature sensor 86 converts the temperature value into an electrical signal and sends it to the PLC controller 12. If the temperature inside the speaker body 1 exceeds the preset warning temperature of the PLC controller 12 due to the high temperature environment or overload operation, the PLC controller 12 promptly controls the vacuum pump 81 to work, and the vacuum pump 81 sucks in the outside air. When the outside air passes through the filter assembly 9, it is filtered and purified by the filter sponge block 93 and the filter screen 94 to remove impurities in the air. The clean air enters the first air pipe 83 through the vacuum pump 81 and the unpowered three-way reversing solenoid valve 82, and finally enters the inside of the speaker body 1, accelerating the air flow inside the speaker body 1. The injected air carries heat and is quickly discharged from the heat dissipation holes of the speaker body 1 itself. The heat dissipation holes are existing technologies for speakers and are not described in detail. The flowing air accelerates heat dissipation to prevent the speaker operation from being affected by high temperature, thereby ensuring that the speaker can continue to work reliably. This mechanism enables the speaker to have the function of active heat dissipation and improves the reliability of the speaker.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
