This invention provides a positioning device for fixing a lapel clip
microphone to the brim of a hat. The device includes a clamping part and a fixing part. The clamping part clamps and fixes the positioning device to the brim of the hat. The fixing part is connected to the clamping part and is used to fix the lapel clip
microphone. When the clamping part is fixed to the brim and the lapel clip
microphone is fixed to the fixing part, the microphone's
pickup port can point downwards towards the bottom of the hat. When used with a hat, this positioning device serves as a base for fixing the lapel clip microphone to the brim, while simultaneously tilting the microphone's
pickup port downwards and pointing it towards the singer's mouth, thereby improving sound
pickup and meeting the requirements for high-quality singing. Furthermore, since it is not in the
airflow path of the mouth, it also avoids plosive sounds.
