[0011] The knob is rotatably disposed between the gooseneck tube and the mounting unit, the first circuit board is fixedly disposed on the gooseneck tube, and the second circuit board is fixedly disposed on the knob;
[0012] The first circuit board has multiple contacts, and the second circuit board has a spring for switching contact with the multiple contacts to achieve switching of the sound pickup mode.
[0013] In some implementations, the outer surface of the knob is provided with multiple anti-slip strips, which prevent slippage when the knob is rotated and also make it easier for the user to identify the position of the knob, thus improving ease of use.
[0014] In some implementations, a mounting groove is formed at the end of the gooseneck tube, and the first circuit board is fixedly disposed in the mounting groove. The mounting groove provides a relatively stable mounting effect for the first circuit board, thereby ensuring the stability of use.
[0015] In some implementations, a first fastener is provided on one end of the knob near the mounting groove, and a first sliding groove is formed at the edge of the mounting groove for rotating contact with the first fastener, so as to realize the connection between the knob and the gooseneck tube at the same time as realizing the rotational contact between the knob and the gooseneck tube.

[0018] In some implementations, the mounting unit includes a mounting base and multiple mounting brackets;
[0019] The mounting base is in rotatable contact with the knob, and a plurality of mounting brackets are disposed on the mounting base at one end away from the knob;
[0020] Each of the microphones is mounted on one of the mounting brackets.
[0021] In some implementations, a second fastener is provided on one end of the knob near the mounting base, and a second groove is formed on the mounting base for rotatably contacting the second fastener, thereby achieving both connection between the knob and the mounting base and rotatable contact between the knob and the mounting base.
[0022] In some implementations, the pickup module further includes a dustproof mesh shell, which is fitted over the outside of the multi-directional pickup unit and connected to the mounting unit.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.
[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0038] Example 1:
[0039] Please see Figure 1 A portable microphone with switchable directionality includes a gooseneck tube 100 and a microphone module 200. One end of the gooseneck tube 100 is connected to the microphone module 200, and the other end of the gooseneck tube 100 is provided with a connection port 300 for connecting to an electronic device.
[0040] The gooseneck tube 100 is used to connect to and freely bend and adjust the angle of the pickup module 200. Its length and radius can be set according to actual needs. The pickup module 200 is used to pick up sound and realize the function of communication. The connection port 300 is used to establish a connection between the pickup device and an electronic device, such as a headset, a laptop, or a Bluetooth speaker.
[0041] The pickup module 200 includes a rotary switching circuit unit 210, a mounting unit 220, and a multi-directional pickup unit 230. The rotary switching circuit unit 210 is disposed between the gooseneck tube 100 and the mounting unit 220. The multi-directional pickup unit 230 is disposed on the mounting unit 220. The multi-directional pickup unit 230 is electrically connected to the rotary switching circuit unit 210. The rotary switching circuit unit 210 is electrically connected to the connection port 300.
[0042] The mounting unit 220 serves to limit the installation of the multi-directional pickup unit 230, and at the same time, it limits the rotary switching circuit unit 210 between the gooseneck tube 100 and the mounting unit 220 to ensure the integrity of the pickup device.
[0043] Understandably, the multi-directional pickup unit 230 has pickup functions in multiple directions, and the pickup functions in each direction can be turned on individually, partially and simultaneously, or all simultaneously. It is known that the multi-directional pickup unit 230 is electrically connected to the rotary switching circuit unit 210. Therefore, the switching of different pickup functions of the multi-directional pickup unit 230 can be achieved by rotating the rotary switching circuit unit 210 to realize a single-directional pickup mode, a multi-directional pickup mode, or an omnidirectional pickup mode, etc., to meet the pickup needs of different scenarios.
[0044] Furthermore, the gooseneck tube 100 has a hollow structure, including a metal layer and a silicone layer. The silicone layer is wrapped around the outer surface of the metal layer, which allows the gooseneck tube 100 to be bent at will while also having a more aesthetically pleasing outer surface, thus improving the user experience.
[0045] The gooseneck tube 100 has a hollow tubular structure. Its hollow interior is used for passing wires, such as for passing the connecting wire between the rotary switching circuit unit 210 and the connection port 300. Of course, it can also be used for passing other connecting wires to realize the complete function of the pickup device.
[0046] The metal layer is equivalent to the inner layer of the gooseneck tube 100. The metal layer has the characteristic of being able to be bent arbitrarily and with a defined direction. That is, after the gooseneck tube 100 is bent arbitrarily, it will maintain its arbitrarily bent shape under the action of no external force. The silicone layer is equivalent to the outer layer of the gooseneck tube 100. Compared with the metal layer, it has a certain aesthetic appeal. The color of the silicone layer can be adjusted according to the needs, such as being set to pink, blue or green.
[0047] This embodiment provides a portable microphone with switchable directional pickup. By setting a rotating switching circuit unit 210 and a multi-directional pickup unit 230, it can switch between a single-directional pickup mode, a multi-directional pickup mode, or an omnidirectional pickup mode according to actual usage needs, meeting the pickup requirements of different scenarios. It can also take advantage of the gooseneck tube 100's ability to bend freely, so that the gooseneck tube 100 can be bent adaptively to ensure that the pickup device is aligned with the mouth, thereby ensuring the pickup effect and call quality.
[0048] Example 2:
[0049] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the pickup device of this utility model. Please refer to [link / reference]. Figure 2 and Figure 3 .
[0050] In this embodiment, the rotary switching circuit unit 210 includes a knob 211, a first circuit board 212, and a second circuit board 213. The knob 211 is rotatably disposed between the gooseneck tube 100 and the mounting unit 220, that is, the knob 211 can rotate relative to the gooseneck tube 100 and the mounting unit 220. The first circuit board 212 is fixedly disposed on the gooseneck tube 100, and the second circuit board 213 is fixedly disposed on the knob 211. The first circuit board 212 is provided with multiple contacts 214, and the second circuit board 213 is provided with a spring piece 215 for switching contact with the multiple contacts 214 to realize the switching of the pickup mode.
[0051] Understandably, the first circuit board 212 is electrically connected to the connection port 300, and the second circuit board 213 is electrically connected to the multi-directional pickup unit 230. The first circuit board 212 and the second circuit board 213 are connected by a spring 215. It is known that the position of the first circuit board 212 is fixed, while the second circuit board 213 will rotate with the knob 211. Therefore, during the rotation of the second circuit board 213, the spring 215 on the second circuit board 213 will switch to contact different contacts 214 on the first circuit board 212, thereby adjusting the multi-directional pickup unit 230 to present different pickup modes.
[0052] Furthermore, multiple anti-slip strips 211a are formed on the outer surface of the knob 211. When the knob 211 is rotated, the anti-slip strips 211a can prevent slipping and also make it easier for users to distinguish the position of the knob 211, thus improving ease of use.
[0053] For example, the knob 211 has a hollow cylindrical structure, including a first end face and a second end face that are arranged opposite to each other. The first end face is used for the fixed connection of the second circuit board 213, and the second end face is used for the connection with the mounting unit 220. The middle part of the knob 211 can be used for the routing of the connection line between the multi-directional pickup unit 230 and the second circuit board 213. Multiple anti-slip strips 211a are evenly distributed on the outer surface of the knob 211 to prevent slippage during the rotation of the knob 211.
[0054] In some embodiments, a mounting groove 110 is formed at the end of the gooseneck tube 100, and the first circuit board 212 is fixedly disposed in the mounting groove 110. The mounting groove 110 provides a relatively stable mounting effect for the first circuit board 212, thereby ensuring the stability of use.
[0055] The first circuit board 212 can be fixedly installed in the mounting groove 110 by means of screw locking or snap-fit limiting connection to ensure the stability of the first circuit board 212 in the mounting groove 110. Similarly, the second circuit board 213 can also be fixedly connected to the knob 211 by means of screw locking or snap-fit limiting connection.
[0056] Furthermore, a first fastener 211b is provided at one end of the knob 211 near the mounting groove 110, and a first sliding groove 111 is formed at the edge of the mounting groove 110 for rotating contact with the first fastener 211b. This achieves the connection between the knob 211 and the gooseneck tube 100, while also achieving rotational contact between the knob 211 and the gooseneck tube 100.
[0057] For example, there are two first fasteners 211b, which are evenly spaced on the first end face of the knob 211. During assembly, the two first fasteners 211b are fastened in the first slide groove 111 under the action of external force, and the first fasteners 211b cannot be disengaged from the first slide groove 111, so that the knob 211 and the gooseneck tube 100 are connected. At the same time, the first fasteners 211b can rotate with the knob 211 during the rotation of the knob 211, thereby realizing the rotational connection between the first fasteners 211b and the first slide groove 111, that is, realizing the rotational contact between the knob 211 and the gooseneck tube 100.
[0058] Example 3:
[0059] The difference between this embodiment and Embodiment 2 is that this embodiment further optimizes the structure of the pickup device of this utility model. Please refer to [link / reference]. Figures 4-7 .
[0060] See Figure 4 In this embodiment, the multi-directional pickup unit 230 includes multiple pickup microphones 231, which are electrically connected to the second circuit board 213. The pickup directions of the multiple pickup microphones 231 are staggered to achieve multi-angle pickup and ensure pickup effect.
[0061] The microphone 231 is an electret condenser microphone, a transducer that converts sound energy into electrical energy output. Multiple microphones 231 are mounted on the mounting unit 220 to achieve multi-mode sound pickup effects. For example, there are three microphones 231 in total, and all three microphones 231 are connected to the second circuit board 213. Depending on the needs of different sound pickup scenarios, the three microphones 231 can pick up sound simultaneously, or they can be switched to one microphone 231 or two microphones 231 for sound pickup. Of course, the number of microphones 231 is not limited here and can be adjusted according to actual needs.
[0062] Correspondingly, the first circuit board 212 is provided with three contacts, namely the first contact, the second contact, and the third contact. When the knob 211 is rotated, it can drive the spring 215 to contact different contacts on the first circuit board 212. When the spring 215 contacts the first contact, the multi-directional pickup unit 230 switches to unidirectional mode, that is, one microphone 231 picks up sound; when the spring 215 contacts the second contact, the multi-directional pickup unit 230 switches to bidirectional mode, that is, two microphones 231 pick up sound; when the spring 215 contacts the third contact, the multi-directional pickup unit 230 switches to panoramic mode, that is, three microphones 231 pick up sound.
[0063] Understandably, the pickup pattern generated by the contact spring 215 making contact with different contacts can be adjusted according to actual needs by adjusting the component layout on the first circuit board 212 or the second circuit board 213 to achieve different circuit control functions.
[0064] In some embodiments, the mounting unit 220 includes a mounting base 221 and a plurality of mounting brackets 222; the mounting base 221 is in rotatable contact with the knob 211, and the plurality of mounting brackets 222 are disposed on the mounting base 221 at the end away from the knob 211; a plurality of microphones 231 are mounted one-to-one on the plurality of mounting brackets 222.
[0065] When there are three microphones 231, there are also three mounting brackets 222, so that the three microphones 231 are installed on the three mounting brackets 222 one by one. To ensure the installation stability of the microphones 231, mounting end faces for supporting the microphones 231 can be formed on the mounting brackets 222. In order to make the adjacent microphones 231 as staggered as possible, the included angle between the adjacent mounting end faces can be set to 120 degrees. In this way, the three microphones 231 can achieve a 360-degree panoramic sound pickup mode.
[0066] See Figure 5 and Figure 6 In some embodiments, a second fastener 211c is provided on one end of the knob 211 near the mounting base 221, and a second groove 221a is formed on the mounting base 221 for rotating contact with the second fastener 211c. This achieves the connection between the knob 211 and the mounting base 221, while also achieving the rotational contact between the knob 211 and the mounting base 221.
[0067] For example, there are two second fasteners 211c. The two second fasteners 211c are evenly spaced on the second end face of the knob 211. During assembly, the two second fasteners 211c are fastened in the second slide groove 221a under the action of external force, and the second fasteners 211c cannot be disengaged from the second slide groove 221a, so that a connection relationship is established between the knob 211 and the mounting base 221. At the same time, the second fasteners 211c can rotate with the knob 211 during the rotation of the knob 211, thereby realizing the rotational connection between the second fasteners 211c and the second slide groove 221a, that is, realizing the rotational contact between the knob 211 and the mounting base 221.
[0068] See Figure 7 In some embodiments, the pickup module 200 further includes a dustproof mesh shell 400, which is fitted over the multi-directional pickup unit 230 and connected to the mounting unit 220. The dustproof mesh shell 400 and the mounting unit 220 can be connected by a snap-fit or screw locking method to facilitate the assembly or disassembly of the dustproof mesh shell 400. Here, by setting the dustproof mesh shell 400, the multi-directional pickup unit 230 is protected from dust and ash, which can ensure the pickup effect of the multi-directional pickup unit 230.
[0069] This utility model provides a portable microphone with switchable directional pickup. By setting a rotating switching circuit unit and a multi-directional pickup unit, it can switch between a single-directional pickup mode, a multi-directional pickup mode, or an omnidirectional pickup mode according to actual usage needs, meeting the pickup requirements of different scenarios. It can also take advantage of the gooseneck tube's ability to bend freely, ensuring that the pickup device is aligned with the user's mouth, thereby ensuring the pickup effect and call quality.
