Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0050] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] See Figures 1 to 7This utility model provides a wireless microphone, including a housing 1, an electronic control component 2, a microphone receiving component 3, and a protective cover component 4; wherein, the electronic control component 2 is connected to the housing 1; the microphone receiving component 3 is installed at one end of the housing 1 and is communicatively connected to the electronic control component 2; the protective cover component 4 is fixedly installed on the upper end of the housing 1 and forms a microphone receiving cavity 40 for accommodating the microphone receiving component 3; the protective cover component 4 includes a bracket 41 and a mesh plate 42, the bracket 41 is provided with a plurality of microphone receiving slots 411, and the mesh plate 42 is disposed on the periphery of the bracket 41; at least part of the outer wall surface of the mesh plate 42 abuts against the inner wall surface of the mesh plate 42.

[0052] It is easy to understand that by setting a sound-receiving groove 411 on the bracket 41 and setting a mesh plate 42 around the bracket 41, the sound-receiving requirements of the wireless microphone can be met, while preventing foreign objects from entering its sound-receiving component 3 and affecting the sound-receiving effect. In addition, the bracket 41 can support the mesh plate 42 and prevent the mesh plate 42 from being excessively deformed due to external forces.

[0053] In order to make the sound receiving component 3 have a better sound receiving effect, in this embodiment, the outer wall surface of the bracket 41 is provided with a plurality of protruding ridges 412; the protruding ridges 412 are supported on the inner wall surface of the mesh plate 42 to form a gap area 5 between the outer wall surface of the bracket 41 and the inner wall surface of the mesh plate 42.

[0062] Furthermore, the inner mounting housing 11 is provided with several support plates 111 for supporting the motherboard 21; the upper end of the inner mounting housing 11 has a wire opening 112. The support plates 111 can increase the support and positioning effect of the motherboard 21, making it easier for the motherboard 21 to be installed stably, while the wire opening 112 facilitates the passage of wires, so that the motherboard 21 can be connected to the radio component 3 through wires, increasing the stability of signal transmission.

[0063] Furthermore, it also includes a display screen 24 electrically connected to the motherboard 21; the display screen 24 is located between the inner mounting shell 11 and the outer decorative shell 12, and the outer decorative shell 12 has a window for the display screen 24 to protrude.

[0064] To facilitate the insertion and charging of the entire wireless microphone, the housing 1 includes an insertion socket 13; the insertion socket 13 is provided with a charging socket 9; the size of the insertion socket 13 gradually decreases from top to bottom to form an insertion guide surface 131.
