Abstract
The present disclosure is a full-duplex wireless voice broadcasting apparatus. The apparatus is capable of channel-changing. Full-duplex (two-way) voice communication is achieved by using at least one receiving device and an emitting device. The receiving device has good mobility to be used as an emergent caller to the emitting device. The present disclosure has advantages in interference resistance, energy saving, short-distance emergent calling, and calling for help.
