Description

Technical Field

[0001] This utility model relates to the field of microphone technology, and in particular to a microphone transmitter. Background Technology

[0002] Traditional wireless microphone transmitters are often limited by the variety of installation methods, resulting in a large overall size. The root cause of this problem lies in the fact that traditional cover installation methods primarily rely on screw fastening. The screws themselves occupy a significant amount of space, and the corresponding screw holes and studs not only take up internal space but also compress the storage area for internal electrical components, making the entire device bulky. This large size makes the device appear awkward when hung on a collar or the front of clothing, and due to its weight, there is a certain risk of accidental detachment, greatly limiting the device's flexibility and convenience in practical applications.
