Description

Technical Field

[0001] The invention belongs to the technical field of audio, and relates to an outdoor pull-rod audio system. Background Art

[0002] Audio equipment, such as digital professional audio equipment or high-fidelity audio products, plays a crucial role in outdoor activities. These equipment are often paired with microphones. Microphones capture the user's voice, which is then digitally processed and amplified by the digital professional audio equipment, providing high-quality sound output and enhancing the auditory experience and atmosphere of outdoor activities.

[0003] Although speakers and microphones are designed to work together, the speaker and microphone are structurally separate, requiring traditional storage methods to separate them, which can be inconvenient for future use. Furthermore, during outdoor activities, microphones are often left unused, making them difficult to use the next time. This not only hinders ease of use but also, due to frequent contact with the user's hands and mouth, makes them a vulnerable medium for the spread of germs. Therefore, in addition to striving for superior sound performance, outdoor audio equipment also requires integrated storage, convenient management, and proper disinfection of the microphones, which are crucial considerations in their application.

[0004] In order to solve the above problems, the present invention proposes an outdoor pull-rod speaker. Summary of the Invention

[0005] In order to solve the problems existing in the background technology, the present invention proposes an outdoor pull-rod speaker.

[0006] In order to achieve the above-mentioned objectives, the technical solution adopted by the present invention is as follows: an outdoor pull-rod speaker, comprising a speaker body and a microphone, a placement cavity for placing the microphone is provided in the speaker body, a liquid storage cavity and a piston cavity are provided in the speaker body, the liquid storage cavity and the piston cavity are one-way connected through a fine channel, an atomizing nozzle is provided at the bottom of the placement cavity, and the piston cavity and the atomizing nozzle are one-way connected through a coarse channel; a piston plate is sealingly and slidingly provided in the piston cavity; the piston plate moves downward so that the disinfectant in the piston cavity enters the coarse channel and is sprayed out through the atomizing nozzle; the piston plate moves upward so that the disinfectant in the liquid storage cavity enters the piston cavity through the fine channel; a support plate is movably provided in the placement cavity, and the support plate and the piston plate are connected; a baffle is slidably provided in the speaker body to block the coarse channel, and the support plate is connected to a trigger assembly cooperating with the baffle, and when the support plate moves up to the upper limit, the baffle opens, and after the support plate moves down to the lower limit, the baffle closes.

[0007] Furthermore, the trigger assembly includes a connecting plate, which is fixedly connected to the supporting plate; a rectangular groove is provided on the connecting plate, and the baffle is fixedly connected to a guide block, and the guide block is slidably provided in the rectangular groove.

[0008] Furthermore, a first magnet and a second magnet are provided in the rectangular slot; the first magnet and the second magnet are respectively located at two vertices on the same diagonal line of the rectangular slot.

[0009] Furthermore, a guide groove is provided on the inner wall of the placement cavity, the guide groove is connected to the piston cavity, a slider is slidably provided in the guide groove, the slider is fixedly connected to a connecting rod, and the connecting rod is fixedly connected to the piston plate; the support plate is connected to the slider; a spring is fixedly connected between the slider and one end wall of the guide groove.

[0010] Furthermore, a ventilation component is provided in the audio body, and the ventilation component includes a fan. The audio body is provided with a first ventilation duct and a second ventilation duct connected to the outside world; the first ventilation duct and the second ventilation duct are both connected to the bottom of the placement cavity, and the fan is installed in the first ventilation duct.

[0011] Furthermore, a push switch is installed at the lower end of the guide groove, and the push switch is connected to the control circuit of the fan. When the slider moves downward and presses the push switch, the fan is started.

[0012] Furthermore, a perforated plate for blocking the first ventilation duct is installed on the speaker body.

[0013] Furthermore, a first filter plate is installed in the first ventilation duct, and a second filter plate is installed in the second ventilation duct.

[0014] Furthermore, a cover plate for shielding the placement cavity is provided above the speaker body.

[0015] Furthermore, a gap is provided on the inner wall of the upper end of the placement cavity.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When the microphone is not in use, it is placed inside the speaker to prevent it from being placed randomly and to facilitate its next use. When the microphone is placed inside the speaker, it can be automatically disinfected, improving the convenience and safety of use.

[0018] The guide block attaches to the first magnet, opening the coarse channel. The microphone is then placed into the cavity, pushing the support plate downward. This allows the disinfectant in the piston chamber to enter the coarse channel and be sprayed out through the atomizing nozzle to disinfect the microphone. When the support plate reaches its lower limit, the trigger assembly closes the coarse channel. After the microphone is removed, the spring forces the slider upward, allowing the disinfectant in the reservoir chamber to enter the piston chamber through the fine channel, replenishing the piston chamber and preparing for the next disinfection.

[0019] Because the inner diameter of the fine channel is smaller, less disinfectant can enter the piston chamber per unit time, causing the support plate to move upward slowly, thereby keeping the coarse channel closed for a certain period of time. When the microphone is placed into the placement chamber with the coarse channel closed, the disinfectant in the piston chamber cannot enter the coarse channel, so the atomizing nozzle will not spray disinfectant. The coarse channel will not open until the microphone has been used for a certain period of time. The microphone will then be disinfected when it is placed inside. This can avoid frequent disinfection of the microphone in a short period of time, which can prevent damage to the microphone caused by frequent disinfection. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0029] like Figure 1-Figure 7 As shown, the technical solution adopted by the present invention is as follows: the outdoor pull-bar speaker includes a speaker body 1 and a microphone 36. The speaker body 1 has a placement cavity 2 with an open top end for accommodating the microphone 36. A clearance notch 3 is provided at the top end of the placement cavity 2 to facilitate storage or removal of the microphone 36. A cover 4 is slidably provided at the top end of the speaker body 1 to cover the placement cavity 2. The cover 4 shields the placement cavity 2 to protect the microphone 36 within the placement cavity 2. A lock 5 is installed on the cover 4.

[0030] A plurality of atomizing nozzles 14 are installed at the bottom of the placement cavity 2 , and disinfectant is sprayed through the atomizing nozzles 14 to disinfect the microphone 36 placed in the placement cavity 2 .

[0031] A piston chamber 9 is provided in the speaker body 1, and a disinfectant is contained in the piston chamber 9. An annular channel 13 and a coarse channel 11 are provided in the speaker body 1, and an atomizing nozzle 14 is connected to the annular channel 13. One end of the coarse channel 11 is connected to the annular channel 13, and the other end of the coarse channel 11 is in one-way communication with the piston chamber 9. A first one-way valve 12 is installed in the coarse channel 11. The disinfectant in the piston chamber 9 flows into the coarse channel 11 through the first one-way valve 12, and then flows through the annular channel 13 to the atomizing nozzle 14. The annular channel 13 sprays the disinfectant toward the microphone 36.

[0032] The speaker body 1 has a liquid reservoir 17 with an open top, allowing for easy addition of disinfectant. A lid 18 is installed on the speaker body 1 to cover the reservoir 17. A small channel 15 is also provided within the speaker body 1, connecting the reservoir 17 with the piston chamber 9. A second one-way valve 16 is installed within the channel 15, allowing disinfectant in the reservoir 17 to flow into the piston chamber 9 through the second one-way valve 16.

[0033] A piston plate 10 is sealed and slidably mounted within the piston chamber 9. When the piston plate 10 moves downward, the disinfectant in the piston chamber 9 flows through the first one-way valve 12 into the coarse passage 11. As the piston plate 10 moves upward, the volume of the piston chamber 9 increases, drawing disinfectant from the reservoir 17 into the piston chamber 9, replenishing the piston chamber 9 with disinfectant.

[0034] Guide grooves 37 are symmetrically defined on the inner wall of the speaker body 1. A slider 7 slides up and down within the guide groove 37, and a spring 8 is fixedly connected between the slider 7 and the lower end wall of the guide groove 37. The slider 7 is fixedly connected to a support plate 6, which slides up and down within the placement cavity 2. The support plate 6 engages with the microphone 36. When the microphone 36 is placed within the placement cavity 2, it presses against the support plate 6, causing it to move downward, forcing the slider 7 to overcome the force of the spring 8 and move downward.

[0035] The lower end of one of the guide grooves 37 is communicated with the piston chamber 9 , and the upper end of the piston plate 10 is fixedly connected to a connecting rod, the upper end of the connecting rod extends into the corresponding guide groove 37 and passes through the spring 8 to be fixedly connected to the slider 7 .

[0036] When microphone 36 is inserted into placement chamber 2, slider 7 moves downward, pushing piston plate 10 downward via the connecting rod. Disinfectant within piston chamber 9 flows into coarse channel 11. Due to the larger inner diameter of coarse channel 11, the disinfectant within piston chamber 9 can flow out quickly. When microphone 36 is removed from placement chamber 2, spring 8 causes slider 7 to move upward, and piston plate 10 to move upward. Due to the smaller inner diameter of fine channel 15, disinfectant within reservoir chamber 17 slowly flows into piston chamber 9, causing piston plate 10 to slowly move upward.

[0037] A baffle 19 is slidably provided in the speaker body 1, and a through hole 20 is provided on the baffle 19, which cooperates with the coarse channel 11. The baffle 19 slides in the speaker body 1 so that the through hole 20 is opposite to or staggered with the coarse channel 11, thereby opening or closing the coarse channel 11.

[0038] A trigger assembly is connected between baffle 19 and the support plate 6 on the same side. When support plate 6 moves to the upper end of guide slot 37, the trigger assembly causes baffle 19 to slide within the speaker body 1, causing through-hole 20 to face coarse passage 11, opening coarse passage 11 and allowing disinfectant in piston chamber 9 to enter coarse passage 11. When support plate 6 moves to the lower end of guide slot 37, the trigger assembly causes baffle 19 to slide within the speaker body 1, causing through-hole 20 to shift away from coarse passage 11, closing coarse passage 11 and preventing disinfectant in piston chamber 9 from entering coarse passage 11.

[0039] The trigger assembly includes a connecting plate 22. The upper end of the connecting plate 22 is fixedly connected to the support plate 6. A rectangular groove is provided on the connecting plate 22, and a guide block 21 is fixedly connected to the baffle 19. The guide block 21 is slidably arranged in the rectangular groove. For ease of description, as shown in FIG. Figure 6As shown, the four sides of the rectangular slot are defined as a first vertical segment 23, a first transverse segment 24, a second vertical segment 25, and a second transverse segment 26. The first vertical segment 23, the first transverse segment 24, the second vertical segment 25, and the second transverse segment 26 are sequentially connected. A first magnet 27 is mounted on the inner wall of the lower end of the first vertical segment 23, and a second magnet 28 is mounted on the inner wall of the upper end of the second vertical segment 25. Both the first magnet 27 and the second magnet 28 engage with the guide block 21 in an adsorbent manner. The guide block 21 is made of iron.

[0040] When the support plate 6 moves upward, the connecting plate 22 moves upward, and the guide block 21 slides along the second vertical section 25 toward the second transverse section 26. When the guide block 21 moves to the lower end of the second vertical section 25, under the adsorption action of the first magnet 27, the guide block 21 moves along the second transverse section 26 toward the first magnet 27 and is adsorbed onto the first magnet 27. The guide block 21 drives the baffle 19 to move, thereby opening the coarse channel 11.

[0041] As the support plate 6 moves downward, the connecting plate 22 also moves downward, and the guide block 21 moves along the first vertical section 23 toward the first transverse section 24. When the guide block 21 reaches the upper end of the first vertical section 23, attracted by the second magnet 28, the guide block 21 slides along the first transverse section 24 toward the second magnet 28 and is attracted to the second magnet 28. The guide block 21 then moves the baffle 19, thereby closing the coarse passage 11.

[0042] A ventilation assembly is also provided in the audio body 1, and the ventilation assembly includes a fan 31 and a push switch 35. A first ventilation duct 29 and a second ventilation duct 33 are provided on the audio body 1. One end of the first ventilation duct 29 and the second ventilation duct 33 are both connected to the outside world, and the other ends of the first ventilation duct 29 and the second ventilation duct 33 are both connected to the bottom of the placement cavity 2. The fan 31 is installed in the first ventilation duct 29. A perforated plate 30 is installed in the audio body 1, and the perforated plate 30 is located at one end of the first ventilation duct 29 close to the placement cavity 2. Under the action of the fan 31, the outside air enters the placement cavity 2 through the first ventilation duct 29 and the perforated plate 30 to blow air to the microphone 36, thereby drying the microphone 36 that has been sprayed with disinfectant, so as to facilitate storage and next use.

[0043] A first filter plate 32 is installed in the first ventilation duct 29 to filter the air entering the first ventilation duct 29 and prevent external impurities from entering the placement chamber 2 through the first ventilation duct 29. A second filter plate 34 is installed in the second ventilation duct 33 to prevent external impurities from entering the placement chamber 2 through the second ventilation duct 33.

[0044] The push switch 35 is connected to the control circuit of the fan 31. The push switch 35 is set at the lower end of the guide groove 37. The slider 7 moves downward to press the push switch 35, thereby turning on the fan 31. The fan 31 will automatically turn off after running for a period of time.

[0045] Working principle: Initially, the guide block 21 is attracted to the first magnet 27, the through hole 20 is opposite to the coarse channel 11, and the coarse channel 11 is in an open state.

[0046] When placing microphone 36 into placement chamber 2, insert the head of microphone 36 downward. Microphone 36 moves downward along chamber 2. When microphone 36 contacts support plate 6, it pushes support plate 6 downward, causing slider 7 to move downward, gradually compressing spring 8. Slider 7, via a connecting rod, pushes piston plate 10 downward, causing the disinfectant in piston chamber 9 to flow through first one-way valve 12 into coarse channel 11, then into annular channel 13, and finally through atomizing nozzle 14 toward microphone 36, disinfecting it.

[0047] When the support plate 6 moves downward, it pushes the connecting plate 22 downward, causing the guide block 21 to break away from the adsorption of the first magnet 27 and move along the first vertical section 23 toward the first transverse section 24. When the support plate 6 moves downward to the lower limit, the support plate 6 stops moving downward, and the microphone 36 stops moving downward. At this time, the guide block 21 is at the upper end of the first vertical section 23. Under the attraction of the second magnet 28, the guide block 21 moves along the first transverse section 24 toward the second magnet 28 and is adsorbed onto the second magnet 28. When the guide block 21 moves along the first transverse section 24, it drives the baffle 19 to move, causing the through hole 20 to be offset from the coarse channel 11, thereby closing the coarse channel 11.

[0048] Slider 7 moves downward, squeezing switch 35 and activating fan 31. Air from the outside enters chamber 2 through first ventilation duct 29 and perforated plate 30, blowing toward microphone 36, drying the disinfectant on microphone 36. The air in chamber 2 then flows out through second ventilation duct 33. Fan 31 automatically stops after running for a period of time. Cover plate 4 is then pushed to cover the upper end of chamber 2.

[0049] Pushing cover plate 4 opens the upper end of chamber 2, allowing microphone 36 to be removed from chamber 2. With microphone 36 no longer in use, spring 8 causes slider 7 and support plate 6 to move upward, leading to piston plate 10 moving upward, allowing disinfectant in reservoir 17 to flow through narrow channel 15 into piston chamber 9. Due to the small inner diameter of narrow channel 15, less disinfectant flows into piston chamber 9 per unit time, slowing slider 7's upward movement.

[0050] During the upward movement of the support plate 6, the support plate 6 drives the connecting plate 22 to move upward, so that the guide block 21 overcomes the adsorption of the second magnet 28 and moves along the second vertical section 25 toward the second transverse section 26. Due to the slow upward movement of the support plate 6, the guide block 21 slowly moves downward along the second vertical section 25. When the guide block 21 is in the second vertical section 25, due to the limitation of the second vertical section 25, the baffle 19 cannot slide, so that the baffle 19 keeps blocking the coarse channel 11, and the coarse channel 11 remains closed. At this time, if the microphone 36 is placed in the placement chamber 2, the disinfectant in the piston chamber 9 cannot be discharged through the coarse channel 11, and no disinfectant is sprayed out through the atomizing nozzle 14, so the microphone 36 will not be disinfected, and the support plate 6 will have difficulty moving downward. At the same time, under the push of the microphone 36, the support plate 6 stops moving upward. That is, when the guide block 21 is in the second vertical section 25, the coarse channel 11 remains closed, and when the microphone 36 is placed in the placement chamber 2, no disinfectant is sprayed toward the microphone 36. After the microphone 36 is removed again, the slider 7 continues to slowly move upward, and the disinfectant in the fine channel 15 enters the piston chamber 9, and the guide block 21 slowly moves downward along the second vertical section 25.

[0051] During actual use, the user may repeatedly take the microphone 36 out of and put it back into the placement cavity 2. If the microphone 36 is disinfected every time it is placed into the placement cavity 2, not only will disinfectant be wasted, but the microphone 36 may also be damaged due to frequent spraying of disinfectant.

[0052] In this device, the guide block 21 can only move to the lower end of the second vertical section 25 after the microphone 36 has been used for a certain period of time, that is, after the microphone 36 has been separated from the placement chamber 2 for a certain period of time. After the guide block 21 moves to the lower end of the second vertical section 25, under the attraction of the first magnet 27, the guide block 21 moves along the second transverse section 26 in the direction close to the first magnet 27 and is adsorbed onto the first magnet 27. When the guide block 21 slides along the second transverse section 26, it drives the baffle 19 to move, thereby opening the coarse channel 11. Afterwards, when the microphone 36 is placed in the placement chamber 2, the microphone 36 pushes the support plate 6 downward, and the disinfectant in the piston chamber 9 flows into the coarse channel 11. This can avoid frequent disinfection of the microphone 36 in a short period of time.

[0053] When the guide block 21 is attracted to the first magnet 27 or the second magnet 28, vibrations generated by the speaker body 1 during operation will not cause the guide block 21 to separate from the first magnet 27 or the second magnet 28, thereby keeping the baffle 19 stably within the speaker body 1 and, in turn, maintaining the coarse duct 11 in the open or closed state. In other words, vibrations generated by the speaker body 1 during operation will not affect the open or closed state of the coarse duct 11.

[0054] When the guide block 21 slides within the first vertical section 23, due to the limitation of the first vertical section 23, when the sound body 1 is in operation and generates vibrations, the baffle 19 cannot move relative to the coarse channel 11, thereby keeping the coarse channel 11 open, and allowing the disinfectant in the piston chamber 9 to flow smoothly into the coarse channel 11. When the guide block 21 slides within the second vertical section 25, due to the limitation of the second vertical section 25, when the sound body 1 is in operation and generates vibrations, the baffle 19 cannot slide relative to the coarse channel 11, thereby keeping the coarse channel 11 closed.

[0055] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. 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.
