Embodiment Construction

[0035] The present invention is described in detail below in conjunction with accompanying drawing:

[0036] Audio systems that do not use the audio input quick switcher such as figure 1 As shown, the microphone 1 is connected to the ground socket 3, the audio processor 5, and the speaker 6 in sequence, and the poor contact caused by the metal oxidation of the ground plug and the violent plugging and unplugging of the XLR head are the main failure points 7 that cause the connection failure of the audio system.

[0037] After adding the fast switching of audio input based on active and standby protection in this patent, the system connection diagram is as follows figure 2 shown. The microphone 1 is connected to the splitter 2, and the output of the splitter 2 is divided into two paths, which are respectively connected to the audio input fast switcher 4 through the ground socket 3, and the audio input fast switcher 4 is connected to the audio processor 5 and the speaker 6 in t...

Abstract

The invention discloses an audio input rapid switcher and switching system based on master and backup protection and working methods. The switcher comprises two ways of audio input signals; one way is master audio input signals; the other way is secondary audio input signals; each way of audio input signals accesses an input interface circuit through A / D conversion; the input interface circuit transmits the audio input signals to a data processing module; the data processing module communicates with a master control unit; and the data processing module compares the two ways of input audio signals in real time and feeds back comparing results to the master control unit. According to the new type audio input rapid switcher, the influence of the fault of a microphone wiring point on an audio system is reduced; and stable and reliable guarantee is provided for a conference.

Description

technical field [0001] The invention relates to the field of conference audio systems, in particular to an audio input fast switcher, system and working method based on active and standby protection. Background technique [0002] Currently widely used in conference system microphones, capacitive gooseneck microphones have the advantages of high sensitivity and good directivity, and are the mainstream wired microphones in the market. However, after using the microphone, it is necessary to unplug the XLR head connected to the sound reinforcement equipment. The metal part of the ground plug is exposed to the air for a long time, which is prone to oxidation and reduces the sensitivity of the connector. At the same time, repeated plugging and unplugging will cause the plug to loosen. , resulting in a potential failure. [0003] Audio signal switchers become an effective solution. There are two types of traditional audio signal switchers: select the signal source by manual switc...
