Abstract

A broadcast intercom system based on an IP network, comprising an IP network intercom host, an IP network intercom extension, and an IP network address box that realize mutual communication through a local area network or a wide area network; the IP network intercom host, the IP network intercom extension Respectively comprising a first voice acquisition module and a core processor integrated with a first duplex echo cancellation circuit, a second voice acquisition module and a core processor integrated with a second duplex echo cancellation circuit, the first voice acquisition module and The second voice collection module includes a first programmable amplifier and a third programmable amplifier respectively, and the audio sampling rate when the first programmable amplifier and the third programmable amplifier perform analog-to-digital conversion is 32K. The invention well improves the sound effect of the duplex intercom.

Description

technical field [0001] The invention relates to the technical field of intercom broadcasting, in particular to an IP network-based broadcast intercom system. Background technique [0002] With the development and progress of IP network technology, the intercom and broadcasting system has been upgraded to a networked and digital platform, which not only improves the stability of the system, facilitates construction and maintenance, but also improves the scalability of the system. [0003] However, the audio sampling rate of the traditional IP network intercom system and IP network broadcasting system is low, and there is an echo in the duplex intercom, which leads to unsatisfactory sound effects. Contents of the invention [0004] Based on this, it is necessary to provide an IP network-based broadcast intercom system that can improve sound effects. [0005] A broadcast intercom system based on an IP network, comprising an IP network intercom host computer, an IP network in...
