[0002] A handheld wireless microphone is a microphone device that uses wireless transmission to break free from the constraints of traditional wired microphones. A handheld wireless microphone consists of a sound wave receiver that includes a vibration membrane and a substrate, and has a built-in high-performance audio processing chip that can provide high-definition audio signals. Through wireless transmission technology (such as VHF, UHF bands, etc.), the sound signal is wirelessly transmitted to the receiver, thereby realizing sound collection and transmission without cable connection.

[0003] Existing handheld wireless microphones usually consist of three parts: a microphone, an operating tube, and a handle. The operating tube is usually provided with buttons. When the handheld wireless microphone is used outdoors, the buttons may get wet due to weather reasons. Once moisture enters the microphone buttons, it will damage the microphone's circuit and form a layer of water film inside the microphone, which will affect the transmission of the voice signal, thereby reducing the recording effect and even causing noise, affecting the service life of the microphone.

[0027] In the specific implementation process, Figure 1-Figure 7 As shown, the handheld wireless microphone provided by the utility model comprises: a microphone body and a protective device arranged on the outer side wall of the microphone body;

[0028] The protective device includes a protective cover 5 and a protective frame 6. The lower end of the protective frame 6 is fixedly connected to one side of the microphone body. The protective cover 5 is installed inside the protective frame 6. The protective cover 5 can slide in the protective frame 6. One side of the protective cover is in contact with one side of the microphone body. When the protective cover 5 completely slides into the protective frame 6, an enclosed space is formed by the protective cover 5 and the protective frame 6. At this time, the microphone body can be protected. A limiting device is provided on the protective cover 5 to limit the protective cover 5.

[0029] The microphone body includes a handle 1, an operating tube 2 and a microphone 3. The upper end of the handle 1 is fixedly connected to the lower end of the operating tube 2, the lower end of the microphone 3 is fixedly connected to the upper end of the operating tube 2, a button group 4 is provided on the operating tube 2, and the lower end of the protective frame 6 is fixedly connected to one end of the operating tube 2 with the button group 4. The above-mentioned button group includes volume plus and minus keys, volume minus keys, a power switch key, a charging port and a display screen.

[0030] Movable holes 7 are provided on opposite sides of the protection frame 6, and limit bars 8 are provided on the upper ends of the two movable holes 7. The two limit bars 8 can be used to limit the protection cover so that the protection cover 5 will not fall off due to excessive sliding when in use.

[0031] Sliding grooves 9 are provided on two relatively vertical sides of the protection frame 6 , and the opposite sides of the protection cover 5 are movably arranged in the two sliding grooves 9 and slide along the two sliding grooves 9 .

[0032] Two limiting holes 10 are provided at the upper end of the protection frame 6 . The two limiting holes 10 correspond to each other in horizontal direction. The limiting holes 10 can be engaged with the limiting rods 11 on the protection cover 5 .

[0033] The protective cover 5 is provided with a limiting groove 16 , and the inner side wall of the limiting groove 16 is provided with a moving groove 17 , and the two moving grooves 17 can allow the limiting device to move therein.

[0034] The limiting device includes a limiting rod 11, a movable block 12, a limiting block 13 and a spring 14. The limiting rod 11 extends into the inner wall of the limiting groove 16, one side of the limiting block 13 is fixedly connected to one end of the limiting rod 11 close to the limiting groove 16, one end of the spring 14 is fixedly connected to one side of the limiting block 13 close to the limiting rod 11, the other end of the spring 14 is fixedly connected to the inner wall of the limiting groove 16, one end of the movable block 12 is fixedly connected to the upper end of the limiting block 13. When the movable block 12 moves, the limiting block 13 will be driven to move, and the movement of the limiting block 13 will drive the limiting rod 11 to move. At this time, the spring 14 will also shrink due to the movement of the limiting block 13. When the movable block is released, the limiting block 13 will move due to the pulling force of the spring 14. At this time, the limiting rod 11 will also be driven to move, and the limiting rod 11 will engage with the limiting hole 7.

[0035] Sliding blocks 15 are provided on opposite sides of the movable block 12 . The sizes of the two sliding blocks 15 correspond to the limiting grooves 16 . The sliding blocks 15 are installed in the limiting grooves 16 so as to allow the movable block 12 to move.

[0036] The working principle of the utility model is as follows: when in use, first slide the movable block 12 downward, at this time the limit rod 11 is separated from the limit hole 10, at this time the limit device releases the restriction, the spring 14 is in a contracted state, at this time the movable block 12 can be slid, the movable block 12 drives the protective cover 5 to move in the same direction of the movable block 12, when the protective cover 5 is slid to the edge, the movable block 12 is released, the elastic force of the spring 14 re-engages the limit rod 11 with the limit hole 10, at this time the protective cover 5 is fixed, and the button group 4 on the operating cylinder will not be blocked, At this time, the button group 4 can be used. After use, the movable block 12 can be slid downward again. At this time, the movable block 12 can be slid again to drive the protective cover 5 to move. When the protective cover 5 completely covers the button group 4, the movable block 12 is released, and the limiting rod 11 is engaged with the limiting hole 10 again, and the protective cover 5 is fixed. At this time, the button group 4 is protected by the protective cover, which solves the problem that in outdoor environments, due to weather reasons, water may enter the button part, and the water may enter the inside of the microphone through the button part, damaging the internal components of the microphone and reducing the service life of the microphone.
