[0002] Handheld microphones, also known as walkie-talkie microphones, are primarily used for voice communication. Users press the transmit button on the microphone and speak into it; the sound is converted into a radio signal and transmitted. Simultaneously, the microphone's speaker receives the other party's voice signal, enabling two-way communication. Handheld microphones are used in transportation, industry, and air traffic control for communication between personnel. They typically include various function buttons, such as volume control and channel switching, allowing users to quickly adjust settings in different environments without directly operating the main unit, thus improving ease of use and efficiency.

[0003] For example, a walkie-talkie with prior art publication number CN208849760U includes a housing, which is divided into a front shell and a rear shell that are connected to each other. The housing has a number of slots for installing buttons, and the slots are equipped with a number of buttons. The housing contains a function processing chip. The front shell is connected to a function board that can be replaced as needed. The rear side of the housing is provided with a back clip that can be hung or clamped. The lower end of the housing is connected to a pluggable and replaceable connecting cable.
