Description

Technical Field

[0001] The invention relates to the field of wireless charging microphone testing, and in particular to a wireless charging microphone and a testing device thereof. Background Art

[0002] A microphone, also called a handset, is an energy conversion device that can convert sound signals into electrical signals. A wireless charging microphone does not require a connection wire. The microphone and the device are wirelessly connected using Bluetooth or other methods, which makes it more convenient to use and can be used after charging. The microphone needs to have its audio tested before it is used.

[0003] Existing microphone testing equipment, for example, the audio testing device and method containing a standard microphone proposed in patent application number "CN201410390063.2" (IPC classification number is H04R29 / 00; H04M1 / 24), uses structures such as an artificial mouth, a bracket, a terminal to be tested, and a standard microphone to place the standard microphone at a position opposite to the reference point of the artificial mouth. The terminal to be tested is supported on one side of the artificial mouth by the bracket, and the standard microphone moves with the fixture and the terminal to be tested, so that the call quality can be accurately and effectively tested no matter where the terminal to be tested moves to, thereby making the audio test more accurate.

[0004] However, there are still certain defects in the prior art. First, the standard microphone is located in front of the pronunciation place (artificial mouth), and the terminal to be tested is located on the side of the artificial mouth. Pronounciation at the pronunciation place will generate airflow, and the airflow directly hits the standard microphone. Therefore, the standard microphone and the terminal to be tested are in different environments, and the audio signals obtained are also different, resulting in an inaccurate test structure: secondly, when the standard microphone and the terminal to be tested are tested together, the sounds generated by the two will interfere with each other, and the anti-interference ability of the microphone cannot be tested. Therefore, a wireless charging microphone and a test device thereof are proposed. Summary of the invention

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0038] A wireless charging microphone and its testing equipment. The wireless charging microphone belongs to the field of digital professional audio equipment. The testing equipment of the wireless charging microphone is a step in the production of human-computer interaction equipment. It is a device used for audio testing of the wireless charging microphone and has the effect of improving the accuracy of audio testing.

[0039] A wireless charging microphone, such as Figure 1-Figure 3 As shown ( Figure 1-Figure 3 The invention relates to a microphone structure without a mesh head installed therein, comprising a shell 50, wherein one end of the shell 50 is threadedly connected to a mesh head fixing frame 51 for installing the mesh head, and the other end is threadedly connected to a tail pipe 58, and a microphone body 57 is inserted into the shell 50, and the microphone body 57 has various parts inside, which is similar to the internal structure of the existing wireless charging microphone and is a prior art. The mesh head fixing frame 51 is electrically connected to one end of the microphone body 57, and a battery slot 55 is provided on one side of the microphone body 57, and a battery pack 54 is clamped in the battery slot 55, and the battery pack 54 is electrically connected to the microphone body 57, and the battery slot 55 runs through the side wall of the shell 50, and a protective cover 52 for protecting the battery pack 54 is clamped on the battery slot 55.

[0040] The wireless charging microphone is powered by a battery pack 54, which is rechargeable. The battery pack 54 and the battery slot 55 of the microphone body 57 are installed by snap-fitting, which is convenient for disassembly and assembly. The connecting surface between the battery pack 54 and the battery slot 55 is provided with a plug-in hole, and the battery slot 55 is provided with a plug-in rod corresponding to the plug-in hole. The plug-in rod is plugged into the plug-in hole, so that the battery pack 54 and the microphone body 57 can be electrically connected. The battery pack 54 of the microphone can be detachably installed on a receiver and other equipment. The battery pack 54 is universal and has a wider range of uses.

[0041] like Figure 1-Figure 3 As shown, the protective cover 52 is provided with a charging port 56, which is electrically connected to the battery pack 54. The charging port 56 is connected to the charging end of the battery pack 54, and the battery pack 54 can be charged through the charging port 56, or the battery pack 54 can be removed and charged. Both sides of the protective cover 52 are fixedly connected with snap fasteners 53, and both sets of snap fasteners 53 are snap-fitted with the outside of the battery slot 55. The protective cover 52 is easy to disassemble and assemble, and the battery pack 54 is easy to disassemble and assemble. A display screen 59 is fixedly connected to one side of the microphone body 57, and the display screen 59 runs through one side of the outer shell 50. A protective cover 60 for protecting the display screen 59 is snapped on the side wall of the outer shell 50. The display screen 59 is used to display information such as the lighting of the wireless charging microphone, and the protective cover 60 prevents the display screen 59 from being easily damaged.

[0042] A test device for a wireless charging microphone, such as Figure 4-Figure 11 As shown, the test equipment includes a test bench 1, and two groups of test components for audio testing of wireless charging microphones are slidably connected to the upper end of the test bench 1. The two groups of test components test the microphone to be tested and the standard microphone respectively. The two groups of components to be tested can be independent or combined. When separated, the two groups of test components form two groups of identical environments, and the microphone to be tested and the standard microphone do not affect each other. When combined, the microphone to be tested and the standard microphone are in the same environment, simulating a scenario where multiple microphones are used simultaneously in the room, and the anti-interference effect of the microphone can be tested. An audio analyzer 2 (model APX500) for connecting to the microphone is fixedly connected to the position of the upper end of the test bench 1 on one side of the two groups of test components. The microphone to be tested and the standard microphone are both connected to the audio analyzer 2, and the audio collected by the two is compared by the audio analyzer 2, so as to test the audio effect of the microphone to be tested.

[0043] The test assembly includes a base 10, which is slidably connected to the upper end of the test bench 1. The two groups of bases 10 are controlled to merge or separate, thereby controlling the two groups of test assemblies to merge or separate. The base 10 slides smoothly and will not affect the structure of the upper end of the base 10. A clamping assembly for supporting and adjusting the position of the microphone is fixedly connected to the upper end of the base 10. The two groups of clamping assemblies respectively adjust the test positions of the standard microphone and the microphone to be tested. After adjustment, the positions of the microphone to be tested and the standard microphone are always the same, so that the microphone can simulate usage scenarios in various positions to improve the fit between the test and actual use. A sound-generating device 19 for playing audio is fixedly connected to the position of the upper end of the base 10 located on one side of the clamping assembly. The sound-generating assembly can be a terminal such as a speaker for providing a sound source. The upper ends of the two groups of bases 10 are both covered with sound insulation covers 3. The clamping assembly and the sound-generating device 19 are both located in the sound insulation covers 3. The sides of the two groups of sound insulation covers 3 that are close to each other are both slidably connected with sound insulation sealing plates 11, and the sides of the two groups of sound insulation covers 3 that are close to each other are sealed and snap-fitted.

[0044] The sound-absorbing pad 14 has a sound-absorbing effect to prevent echoes from being generated inside the soundproof cover 3. The soundproof cover 3 and the soundproof sealing plate 11 soundproof each group of test components, not only isolating the sound between the two groups of test components, but also isolating the sound between the test environment and the external environment, preventing the microphone to be tested and the standard microphone from interfering with each other, and also preventing the sound of the external environment from interfering with the test results. When the two groups of soundproof covers 3 are merged, the two groups of soundproof sealing plates 11 are pulled upward to a certain extent, and a space is formed inside the two groups of soundproof covers 3. The two groups of microphones are kept in the position before the soundproof covers 3 are merged, and the audio at this time is obtained and compared with the audio obtained before the soundproof covers 3 are merged, so as to test the anti-interference ability of the microphone to be tested and the standard microphone.

[0045] like Figure 4 , Figure 5 , Figure 8 As shown, one side of one group of the sound insulation covers 3 is provided with a mounting groove 12, and one side of the other group of the sound insulation covers 3 is fixedly connected with a sealing frame 13, the sealing frame 13 is snap-fitted with the mounting groove 12, and the sealing frame 13 and the mounting groove 12 are both located between the two groups of sound insulation sealing plates 11, and the inner walls of the two groups of sound insulation covers 3 are bonded with sound-absorbing pads 14.

[0046] When the two groups of sound insulation covers 3 are combined, the sealing frame 13 is sealed and clamped with the installation groove 12, and the two groups of sound insulation sealing plates 11 are pulled upward to form a space between the two groups of sound insulation covers 3. The sound absorbing pad 14 can also be installed on one side of the sound insulation sealing plate 11. The sound absorbing pad 14 increases the sound insulation effect of the sound insulation cover 3, thereby improving the sound insulation effect of the test component.

[0047] like Figure 4 , Figure 5 , Figure 7 , Figure 8As shown, the upper end of the sound insulation sealing plate 11 is located at the upper end of the sound insulation cover 3, and two groups of sound insulation sealing plates 11 are symmetrically provided with two groups of tooth grooves 18 on one side inside the sound insulation cover 3, and the two groups of tooth grooves 18 are vertically arranged with the upper end of the base 10, and knobs 15 are rotatably connected to both sides of the sound insulation cover 3, and one end of the two groups of knobs 15 located inside the sound insulation cover 3 is fixedly connected with driving gears 16, and the two groups of driving gears 16 are respectively meshed with the two groups of tooth grooves 18 for transmission, and two groups of elastic damping blocks 17 are symmetrically fixedly connected to the inner wall of the sound insulation cover 3, and the two groups of elastic damping blocks 17 are respectively squeezed and matched with the two groups of driving gears 16.

[0048] When the two groups of sound insulation covers 3 are combined, the knob 15 is rotated, the driving gear 16 is meshed with the tooth groove 18 for transmission, and the sound insulation sealing plate 11 is driven to move upward. The elastic damping block 17 is always pressed against the driving gear 16. When the driving gear 16 stops rotating, the elastic damping block 17 prevents the driving gear 16 from rotating on its own, preventing the sound insulation sealing plate 11 from pressing down and driving the driving gear 16 to rotate, thereby better positioning the sound insulation sealing plate 11.

[0049] like Figure 5 As shown, side seats 4 are fixedly connected to both sides of the upper end of the test bench 1, and a double-headed threaded rod 5 is rotatably connected between the two groups of side seats 4. A servo motor 8 is fixedly connected to one side of one group of side seats 4, and the output end of the servo motor 8 is fixedly connected to one end of the double-headed threaded rod 5. The side walls at both ends of the double-headed threaded rod 5 are threadedly connected with a pressure plate 6 for squeezing the side wall of the sound insulation cover 3, and the threads at both ends of the double-headed threaded rod 5 rotate in opposite directions. One end of the two groups of pressure plates 6 are slidably connected to one side of the test bench 1 through a limit block 7, one side of the pressure plate 6 is slidably connected to the upper end of the test bench 1, and one end is slidably connected to the side of the test bench 1, which effectively prevents the pressure plate 6 from rotating with the rotation of the double-headed threaded rod 5.

[0050] Slide the two groups of test components and merge the two groups of sound insulation covers 3. When the sound inside the sound insulation covers 3 is loud, it is easy to cause the test components to vibrate, resulting in the separation of the two groups of sound insulation covers 3, thereby reducing the sound insulation effect. Therefore, after the two groups of sound insulation covers 3 are merged, the servo motor 8 (model 110ST-M05030) drives the double-headed threaded rod 5 to rotate. Since the threads at both ends of the double-headed threaded rod 5 rotate in opposite directions, and one end of the two groups of pressure plates 6 are slidably connected to one side of the test bench 1 through the limit block 7, the two groups of pressure plates 6 and the sound insulation covers 3 are symmetrically arranged. Therefore, the two groups of pressure plates 6 will be squeezed on both sides of the two groups of sound insulation covers 3, and the two groups of sound insulation covers 3 will be tightly merged to prevent the sound insulation covers 3 from detaching due to vibration.

[0051] like Figure 8-Figure 11As shown, the clamping assembly includes two groups of cylinders 21 (model CJ2L16-60) fixed to the upper end of the base 10 via a mounting seat, the output ends of the two groups of cylinders 21 extend in a vertical direction, and the output ends of the two groups of cylinders 21 are rotatably connected to connecting arms 22, the ends of the two groups of connecting arms 22 are rotatably connected, and the middle parts of the two groups of connecting arms 22 are rotatably connected to support arms 23, one group of support arms 23 ends are fixedly connected to a connecting ring 24, and the other group of support arms 23 ends are fixedly connected to a connecting sleeve 25, the connecting ring 24 is sleeved on the outside of the connecting sleeve 25, and the connecting ring 24 is rotatably connected to the connecting sleeve 25, the corresponding cylinders 21 inside the two groups of test assemblies are in the same state, and the state of the clamping assemblies of the two groups of test assemblies can be strictly controlled by the existing technology to ensure that the positions of the microphone to be tested and the standard microphone corresponding to the sound-emitting device 19 are the same.

[0052] When the output ends of the two groups of cylinders 21 extend, the angle between the two groups of connecting arms 22 decreases, the angle between the two groups of supporting arms 23 decreases, and the connecting part of the connecting sleeve 25 and the connecting ring 24 approaches the sound-emitting device 19 in the middle and front of the two groups of cylinders 21; when the output ends of the two groups of cylinders 21 shrink, the opposite effect is produced; the output ends of the two groups of cylinders 21 operate in the same way to control the forward and backward movement of the connecting part of the connecting sleeve 25 and the connecting ring 24.

[0053] When the output ends of the two groups of cylinders 21 operate in different ways, the connection part is pulled by the connecting arm 22 and the supporting arm 23, so that the connection part between the connecting sleeve 25 and the connecting ring 24 can be controlled to tilt and move left and right.

[0054] like Fig.11 As shown, a connecting shaft 26 passes through the middle of the connecting sleeve 25 and is rotatably connected thereto. The connecting sleeve 25 and the connecting shaft 26 will not drive each other to rotate. A toothed disc 28 is rotatably connected to the upper end of the connecting shaft 26. A supporting threaded rod 29 passes through the middle of the connecting shaft 26. The supporting threaded rod 29 passes through the toothed disc 28, and the side wall of the supporting threaded rod 29 is threadedly connected to the middle of the toothed disc 28. A protrusion 31 is fixedly connected to the inner wall of the connecting shaft 26. A vertical groove 30 is provided on the side wall of the supporting threaded rod 29. The protrusion 31 is slidably connected to the vertical groove 30. A test stand 46 for mounting a microphone is fixedly connected to the upper end of the supporting threaded rod 29.

[0055] The supporting threaded rod 29 is installed through the toothed disc 28 and the connecting shaft 26. The test frame 46 is used to install the microphone. When the toothed disc 28 rotates, the toothed disc 28 drives the supporting threaded rod 29 to rotate through the thread. The supporting threaded rod 29 drives the connecting shaft 26 to rotate through the vertical groove 30 and the protrusion 31, thereby changing the direction of the microphone.

[0056] like Figure 8-Figure 11As shown, the side wall of the connecting shaft 26 is rotatably connected to a connecting plate 27, the upper end of the base 10 is rotatably connected to a rotating seat 40, a driving member 41 is installed inside the rotating seat 40 (the driving member 41 is a motor, model TF-N20FN20), the output end of the driving member 41 passes through the upper end of the rotating seat 40, and a toothed disc 42 is fixedly connected to the output end of the driving member 41, a connecting frame 36 is fixedly connected to one side of the rotating seat 40, and one end of the connecting plate 27 is slidably connected to the connecting frame 36.

[0057] When the two groups of cylinders 21 are running and the position of the connecting shaft 26 is adjusted, the connecting plate 27 slides relative to the connecting frame 36 as the position of the connecting shaft 26 changes, and the connecting plate 27 and the connecting frame 36 drive the rotating seat 40 to rotate, so that the rotating seat 40 can be adjusted as the position of the connecting shaft 26 changes to avoid structural jamming. The driving member 41 is used to indirectly drive the gear disc 28 to rotate.

[0058] like Figure 8-Figure 11 As shown, the upper end of the connecting plate 27 is rotatably connected to a connecting rod 37 via a mounting plate, and the upper end of the connecting frame 36 is rotatably connected to a connecting cylinder 38 via a mounting plate. One end of the connecting rod 37 is plug-connected to the connecting cylinder 38, and the connecting rod 37 and the connecting cylinder 38 cannot rotate relative to each other. The other end is fixedly connected to a gear 1 35, and the gear 1 35 is meshed with a toothed disc 1 28 for transmission. The end of the connecting cylinder 38 away from the gear 1 35 is fixedly connected to a gear 2 39, and the gear 2 39 is meshed with a toothed disc 2 42 for transmission.

[0059] When the two groups of cylinders 21 are running and the position of the connecting shaft 26 is adjusted, the connecting plate 27 slides relative to the connecting frame 36 as the position of the connecting shaft 26 changes, and the connecting rod 37 and the connecting tube 38 are pulled and slid by the connecting plate 27 and the connecting frame 36, changing the total length formed by the connecting rod 37 and the connecting tube 38, and the driving member 41 drives the second gear plate 42 to rotate, and the second gear plate 42 drives the second gear 16 to rotate, and the second gear 39 drives the first gear 16 to rotate through the connecting tube 38 and the connecting rod 37, so that the first gear 35 drives the first gear plate 28 to rotate.

[0060] like Fig. 9 and Fig.11 As shown, a magnetic ring 32 is fixedly connected to the upper part of one end of the connecting plate 27, and the magnetic ring 32 is sleeved on the outside of the connecting shaft 26. A plurality of sets of electromagnetic blocks 33 are fixedly connected to the side wall of the connecting shaft 26 above the magnetic ring 32. The plurality of sets of electromagnetic blocks 33 are magnetically engaged with the magnetic ring 32. A power supply component 43 is fixedly connected to the upper end of the base 10 via a mounting seat, and the power supply component 43 is electrically connected to the plurality of sets of electromagnetic blocks 33 via a power line 45.

[0061] The power supply assembly 43 is provided with a switch to control whether the electromagnetic block 33 is energized. When the multiple groups of electromagnetic blocks 33 are not energized, the electromagnetic blocks 33 and the magnetic ring 32 are not magnetically attracted, and the electromagnetic blocks 33 can slide on the magnetic ring 32. The gear disc 28 rotates to drive the supporting threaded rod 29 to rotate, and the supporting threaded rod 29 rotates to drive the connecting shaft 26 to rotate, and the microphone fixed at the upper end of the supporting threaded rod 29 through the test frame 46 can be turned.

[0062] When multiple groups of electromagnetic blocks 33 are energized, the electromagnetic blocks 33 are magnetically attracted to the magnetic ring 32, and the electromagnetic blocks 33 cannot slide on the magnetic ring 32. Since the magnetic ring 32 is fixedly connected to the connecting plate 27, the connecting plate 27 cannot rotate around the connecting shaft 26, so the connecting shaft 26 cannot rotate. The connecting shaft 26 is slidably connected to the vertical groove 30 of the supporting threaded rod 29 through the protrusion 31, so that the supporting threaded rod 29 cannot rotate. When the toothed disc 28 rotates, since the center of the toothed disc 28 is threadedly connected to the supporting threaded rod 29, the supporting threaded rod 29 can only slide relative to the connecting shaft 26. Therefore, the supporting threaded rod 29 slides up and down relative to the toothed disc 28, so that the microphone fixed on the upper end of the supporting threaded rod 29 can be adjusted up and down.

[0063] The working principle of a wireless charging microphone and its testing equipment provided by the present invention is as follows:

[0064] When in use, the microphone to be tested and the standard microphone are respectively fixed on two groups of test frames 46, the two groups of clamping components are adjusted, the positions of the microphone to be tested and the standard microphone are changed, the soundproof cover 3 is used to cover them, the sound-emitting device 19 is controlled to make sounds, the two groups of microphones collect audio and transmit it to the audio analyzer 2 for comparison, the two groups of test components are isolated by the soundproof cover 3, and two identical test environments are created. The sounds produced by the two will not interfere with each other, thereby improving the test accuracy, the two groups of test components are controlled to be merged, the soundproof sealing plate 11 is lifted, the microphone to be tested and the standard microphone are in the same room, simulating the situation where multiple microphones are used at the same time in the room, and the anti-interference ability of the microphone can be tested, with more comprehensive functions.

[0065] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
