IP network ceiling speaker is an embedded sound reinforcement device that transmits audio signals based on TCP/IP protocol. It receives audio commands from paging microphones and servers through local area network or wide area network, and realizes functions such as zone broadcasting and emergency broadcasting. It is the terminal sound core of IP audio system.

Core functions and typical application scenarios

（1） Core Function Matrix

Audio reception and playback: Supports receiving partitioned broadcasts and point-to-point paging audio, with a response delay of<100ms, and can automatically adapt to the priority settings of the paging microphone; ​
