Detailed Embodiment

[0018] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] As Figures 1-4 shown, a multifunctional Bluetooth microphone proposed in an embodiment of the present invention includes: A holding cylinder 1, the upper end of the holding cylinder 1 is connected to a Bluetooth box 2, and the upper end of the Bluetooth box 2 is detachably connected to a sound receiving cover 3. Among them, the holding cylinder 1 is part of the battery box of the existing Bluetooth microphone, mainly used for storing batteries and for personnel to hold and use. The inside of the Bluetooth box 2 is used to install a control main board, which is electrically connected to the microphone component in the sound receiving cover 3 and the battery in the holding cylinder 1; A folding support frame 4, a plurality of vertical grooves 401 are circumferentially arranged on the holding cylinder 1, the top of the vertical grooves 401 is hinged with telescopic rods 402, the number of vertical grooves 401 is three, so the number of telescopic rods 402 is also three. An automatic strut 403 is arranged between the middle of the telescopic rods 402 and the vertical grooves 401. It should be noted that the holding cylinder 1 is integrally arranged in an inverted frustum shape, and the vertical grooves 401 are arranged along the downward inclination direction of the holding cylinder 1. When the telescopic rods 402 are turned over by the automatic strut 403 and expanded, an included angle can be formed with the holding cylinder 1, and at the same time, the telescopic rods 402 are extended, so as to form a tripod structure to stably support the holding cylinder 1; Bamboo joint limiting sleeve 5, sleeved and installed on the holding cylinder 1 and used to wrap the limiting telescopic rod 402. One side of the Bluetooth box 2 is constructed with a connecting convex block 6 that can be sleeved with one end of the bamboo joint limiting sleeve 5. The device is divided into two states. One is the portable state, as shown in Figure 1 shown. The other is the placement state, as shown in Figure 2 shown. When the telescopic rod 402 is flipped and extended to form a tripod structure, it is in the placement state. When it is necessary to switch to the portable state, only need to retract the telescopic rod 402, then retract it into the vertical groove 401, and finally use the bamboo joint limiting sleeve 5 to sleeve the holding cylinder 1 to limit the movement of the telescopic rod 402 so that it cannot be pushed out of the vertical groove 401 by the automatic strut 403, which is convenient for personnel to carry and hold. The two states can be flexibly switched, increasing the convenience of the device; Sound collection ring 7, detachably inserted at the upper end of the Bluetooth box 2 and sleeved at the bottom end of the sound collection cover 3. The sound collection ring 7 is detachably connected to the other end of the bamboo joint limiting sleeve 5. When the device is in the portable state, the sound collection ring 7 is sleeved on the sound collection cover 3 and serves as a sound collection component together with the sound collection cover 3, which is convenient for personnel to hold and use the device during activities and increases convenience. When the device is in the placement state, the sound collection cover 3 can be detached and the sound collection ring 7 can be taken out. At this time, the bamboo joint limiting sleeve 5 also detaches from the holding cylinder 1. The bamboo joint limiting sleeve 5 can be contracted and sleeved on the connecting convex block 6 on the Bluetooth box 2. At this time, the sound collection ring 7 can be installed on the bamboo joint limiting sleeve 5 to form a position state horizontally opposite to the sound collection cover 3, serving as an additional supplementary sound collection component, which can receive a larger range of sound diffusion ripples and improve the accuracy of sound collection; Adjustable fill light 8, installed at the lower end of the Bluetooth box 2 and sleeved outside the holding cylinder 1. When the device is in the portable state, the adjustable fill light 8 is at the bottom end of the Bluetooth box 2 and is not used. When the device is in the placement state, the position of the adjustable fill light 8 can be adjusted to adjust the light range and light intensity, so that the light source shines more gently on the face of the person, ensuring the clarity of the face of the live broadcast personnel and increasing the functionality of the device.

[0020] As shown in Figure 3 、 Figure 4 and Figure 7 shown, the specific connection structures of the holding cylinder 1, the Bluetooth box 2 and the sound collection cover 3 of the present invention are disclosed, which is convenient for disassembly and installation. Inner threaded tubes 101 are constructed at the upper end of the holding cylinder 1 and the lower end of the sound collection cover 3. Step grooves 201 are constructed at both the upper and lower ends of the Bluetooth box 2. External threaded tubes 202 that are threadedly connected to the inner threaded tubes 101 are constructed in the step grooves 201. The detachable connection of the holding cylinder 1, the Bluetooth box 2 and the sound collection cover 3 can be realized by using the inner threaded tubes 101 and the external threaded tubes 202, which is convenient for the installation and disassembly of the battery in the holding cylinder 1 and the installation and disassembly of the sound collection ring 7, increasing the flexibility of the device.

[0021] As shown in Figures 4-5As shown, the specific structure of the telescopic rod 402 of the present invention is disclosed, which can realize the automatic extension function. The bottom end of the grip tube 1 is configured with a groove 102 connected to a plurality of vertical grooves 401. The telescopic rod 402 includes a flip rod 4021 hinged in the vertical groove 401. The bottom end of the flip rod 4021 is configured with a sliding hole 4022. An extension rod 4023 is slidably installed in the sliding hole 4022. A support spring 4024 is connected between the extension rod 4023 and the inner end of the sliding hole 4022. The bottom end of the extension rod 4023 abuts against the bottom end of the vertical groove 401. The sliding hole at the bottom end of the flip rod 4021 is configured with a sliding hole 4022. 4022 and the extension rod 4023 are in a sliding fit relationship, and the support spring 4024 therebetween can serve as an elastic support structure. It should be noted that the elastic force of the support spring 4024 is greater than the gravity of the entire device. In the absence of external force, it will not be compressed by gravity, which can effectively ensure the stable placement of the device. When the telescopic rod 402 is separated from the bottom end of the vertical groove 401, the extension rod 4023 can be automatically popped out, so that the telescopic rod 402 is automatically extended, so that the telescopic rod 402 passes over the bottom end of the holding tube 1 to contact the desktop, which can better support the device body.

[0022] like Figure 5 As shown, the specific structure of the automatic support rod 403 of the present invention is disclosed, which ensures that the telescopic rod 402 can be automatically expanded to save manpower. An embedding groove 4025 is constructed in the middle of the flip rod 4021 along its length direction. The automatic support rod 403 includes a support rod 4031 hinged at one end in the embedding groove 4025. A sliding groove 4011 is constructed in the vertical groove 401 along its length direction. A slider 4032 slidably installed in the sliding groove 4011 is hinged at the other end of the support rod 4031. A guide rod 4033 that slides through the slider 4032 is installed in the sliding groove 4011. The guide rod 4033 is used to guide the movement of the slider 4032 and prevent the slider 4032 from escaping from the sliding groove 4011 to ensure safety. A compression spring 4033 sleeved on the guide rod 4033 is connected between the slider 4032 and the end of the sliding groove 4011. 4. It should be noted that the compression spring 4034 always provides an elastic thrust to the slider 4032, causing it to move upward. When the telescopic rod 402 loses its limit, that is, the bamboo limit sleeve 5 is separated from the holding tube 1, the compression spring 4034 will push the slider 4032 to slide upward along the sliding groove 4011, and the slider 4032 will drive the support rod 4031 to flip, thereby supporting the flip rod 4021 to flip out of the vertical groove 401. At this time, the friction between the bottom end of the vertical groove 401 and the extension rod 4023 is separated, and the extension rod 4023 loses its obstruction and can be automatically popped out by the elastic force of the support spring 4024 to realize the automatic extension function. In this way, a tripod structure can be formed to stabilize the support device as a whole, so that the device can be placed on the desktop more stably, which is convenient for personnel to use. There is no need for personnel to support the holding tube 1, saving manpower.

[0023] likeFigure 3 and Figure 6 As shown in Figure 6 , the specific structure of the bamboo joint limiting sleeve 5 of the present invention is disclosed, enabling it to have a telescopic function. The bamboo joint limiting sleeve 5 includes a bottom plate 501 and a top ring 502. A plurality of mutually sleeved conical rings 503 are connected between the bottom plate 501 and the top ring 502. A conical insertion tube 5031 is constructed at the upper end of the conical ring 503, and a conical limiting groove 5032 for sleeving the conical insertion tube 5031 is constructed at the lower end of the conical ring 503. It should be noted that the conical ring 503 is similar to the existing fishing rod structure. Through the mutual insertion of the conical insertion tube 5031 and the conical limiting groove 5032, telescopic movement can be achieved, and after moving to a certain extent, it can be limited by friction to prevent detachment after extension. When the bamboo joint limiting sleeve 5 extends to the longest, it is used to sleeve the holding tube 1, which can completely cover the outer surface of the holding tube 1 and at the same time limit the telescopic rod 402 to prevent it from automatically popping out. At this time, the device is convenient for personnel to hold and use. When the bamboo joint limiting sleeve 5 is contracted by the mutual sleeving of the conical rings 503, the conical rings 503 can be in contact with each other at the head and tail to form a contraction. At the same time, the top ring 502 can be used to sleeve it on the connecting convex block 6 to form an extension on one side of the Bluetooth box 2. Then, the sound receiving ring 7 is connected to the bottom plate 501. In this way, while the sound receiving ring 7 is arranged on one side of the sound receiving cover 3, the distance between the sound receiving ring 7 and the sound receiving cover 3 is increased, improving the range of supplementary sound reception. At the same time, the telescopic function of the bamboo joint limiting sleeve 5 can be used to further adjust the distance, increasing the flexibility of the device.

[0024] As Figure 3 、 Figure 6 and Figure 7 As shown in Figure 3 , Figure 6 , and Figure 7 , the connection structures of the bamboo joint limiting sleeve 5 of the present invention with the holding tube 1 and the connecting convex block 6 are disclosed, facilitating installation and disassembly. A rubber block 5011 that is inserted into the groove 102 is constructed on the bottom plate 501. The rubber block 5011 can be tightly inserted into the groove 102 at the bottom end of the holding tube 1. Using friction, the bamboo joint limiting sleeve 5 can be prevented from easily detaching from the holding tube 1, ensuring the safety of personnel during holding. Perforations 5012 are constructed on the bottom plate 501, the rubber block 5011, and the connecting convex block 6. A plurality of clamping grooves 5021 are constructed along the circumference of the inner side of the top ring 502, and a clamping block 5022 that is engaged with the clamping groove 5021 is constructed on the connecting convex block 6. The clamping groove 5021 and the clamping block 5022 are provided to make the bamboo joint limiting sleeve 5 more stable after being sleeved on the connecting convex block 6, preventing the two from easily detaching and increasing safety. When the device switches states, the state of the bamboo joint limiting sleeve 5 needs to change telescopically first. When the device is in a convenient state, the bamboo joint limiting sleeve 5 is in an extended state and then sleeved on the holding tube 1, inserting the rubber block 5011 into the groove 102 to achieve connection. When the device is in a placed state, the bamboo joint limiting sleeve 5 is in a contracted state and then sleeved on the connecting convex block 6 to achieve the horizontal position extension of the sound receiving ring 7.

[0025] As shown in Figure 3 and Figure 6 shown, the specific structure of the sound receiving ring 7 of the present invention is disclosed. The sound receiving ring 7 includes a sound supplement ring 701 sleeved at the bottom end of the sound receiving cover 3. Two limiting blocks 702 are constructed inside the sound supplement ring 701. Anti-detachment grooves 703 for clamping the limiting blocks 702 are constructed on both the bottom end of the sound receiving cover 3 and the bottom plate 501. The sound supplement ring 701 is a conventional microphone structure, but its shape is annular. Limiting blocks 702 are constructed on its outer shell for connecting with the anti-detachment groove 703 of the sound receiving cover 3, so as to prevent the sound supplement ring 701 from rotating and ensure the stability of the installation structure.

[0026] As shown in Figure 3 and Figure 6 shown, the electrical connection structure of the sound receiving ring 7 of the present invention is disclosed. To ensure that the sound receiving ring 7 can still be successfully connected after the device switches states, plug connectors 7021 are constructed at the bottom ends of the limiting blocks 702. Receiving holes 7022 connected to the plug connectors 7021 are constructed on the Bluetooth box 2. Two semi-circular connectors 9 are inserted into the through holes 5012. One end of each semi-circular connector 9 is provided with a movable wire 901 connected to the Bluetooth box 2. A connection groove 902 for sleeving the plug connector 7021 is constructed on one side of the semi-circular connector 9. The plug connector 7021 can be electrically connected to the receiving hole 7022 to realize the connection control between the sound supplement ring 701 and the control main board in the Bluetooth box 2. By setting the semi-circular connectors 9 and the movable wires 901, when the device is in a portable state, the movable wires 901 can be stored inside the Bluetooth box 2, and the semi-circular connectors 9 are inserted into the through holes 5012 of the connecting convex block 6, which will not affect the portable use of the device. When the device switches to the placement state, the bamboo joint limiting sleeve 5 is sleeved on the connecting convex block 6, and the three through holes 5012 communicate with each other. The semi-circular connectors 9 can be pulled out and penetrate through the three through holes 5012. At the same time, the movable wires 901 are also pulled out and penetrate through the three through holes 5012. Finally, the connection groove 902 on the semi-circular connector 9 is sleeved with the plug connector 7021 to realize electrical connection again. The operation is fast and the switching is flexible, increasing the convenience of the device.

[0027] As shown in Figure 7As shown, the specific structure of the light supplementing member 8 of the present invention is disclosed to ensure the illumination of the human face and improve the live broadcast effect. The light supplementing member 8 includes lifting rods 801 arranged at the four corners of the bottom end of the Bluetooth box 2. The bottom end of the lifting rod 801 is connected with a mounting ring 802. A light-emitting ring 803 is fixedly connected to the outer side of the mounting ring 802. Two insertion rods 804 are formed on the upper side of the mounting ring 802. Two limiting bumps 203 for tightly sleeving the insertion rods 804 are formed on the bottom end of the Bluetooth box 2. When the device is in a portable state, most of the time when a person holds the device, at this time, the human face generally does not need to use the light supplementing member 8 for light supplement. Therefore, the insertion rods 804 can be tightly sleeved with the limiting bumps 203, and the frictional force is used to prevent the mounting ring 802 from easily detaching, ensuring the structural stability of the device when it is held and carried. When the device is in a placed state, the light-emitting ring 803 can be arranged at the bottom end of the Bluetooth box 2 through the lifting rod 801. It should be noted that the diameter of the light-emitting ring 803 is greater than the length of the Bluetooth box 2. When the light-emitting ring 803 is closer to the Bluetooth box 2, the light will be closer to the human face, and the illumination intensity will be stronger. On the contrary, the light will be farther from the human face, and the illumination intensity will be weaker. By adjusting the height of the light-emitting ring 803 with the lifting rod 801, the illumination intensity can be effectively adjusted to flexibly adapt to different environmental scenarios and increase the functionality and adaptability of the device.

[0028] As Figures 7-8As shown, the specific structure of the lifting rod 801 of the present invention is disclosed to achieve flexible adjustment of the light intensity. Storage grooves 204 are constructed at the four corners of the bottom of the Bluetooth box 2. The lifting rod 801 includes an L-shaped vertical plate 8011 slidably installed in the storage groove 204. A stop block 2041 for blocking the downward movement of the L-shaped vertical plate 8011 is constructed at the bottom end of the storage groove 204. An arc-shaped elastic plate 8012 is constructed on the outer side of the L-shaped vertical plate 8011. An extension frame plate 8013 is slidably sleeved on the arc-shaped elastic plate 8012. Stop pieces 8014 are constructed at the upper end of the extension frame plate 8013 and the lower end of the arc-shaped elastic plate 8012 in a relatively arranged manner. The bottom end of the extension frame plate 8013 is connected to the mounting ring 802. When it is necessary to adjust the height of the light-emitting ring 803, the user only needs to press the mounting ring 802 downward. At this time, the L-shaped vertical plate 8011 slides in the storage groove 204, and the extension frame plate 8013 slides on the arc-shaped elastic plate 8012 to achieve the extension operation and reduce the height of the light-emitting ring 803. When the light-emitting ring 803 is stored, it needs to be pushed upward. The L-shaped vertical plate 8011 is retracted into the storage groove 204, and the extension frame plate 8013 is reset to the position flush with the L-shaped vertical plate 8011, and the light-emitting ring 803 rises, so that the insertion rod 804 on the mounting ring 802 is sleeved with the limit convex block 203 to achieve storage. It should be noted that there is friction between the L-shaped vertical plate 8011 and the storage groove 204, and its friction is greater than the gravity of the mounting ring 802 and the light-emitting ring 803. Therefore, the self-locking effect can be achieved by using the friction. The arc-shaped elastic plate 8012 uses the elastic force to increase the friction with the extension frame plate 8013 to achieve the self-locking effect, ensuring that the mounting ring 802 can be stably in this position after adjusting the height, so as to ensure the light intensity.
