Tabletop microphone supporting PTT hardware detection function

Abstract

The invention discloses a tabletop microphone supporting a PTT hardware detection function. The tabletop microphone comprises a PTT press key, a single key keyboard module, a movable ring microphone,an audio frequency wire and a USB data wire, wherein the PTT press key uses a button switch; the button switch has two contacts; the contacts are used for detecting states of the PTT press key; when the press key is pushed down by external force; the two contacts are in a conduction state; the single key keyboard module is used for generating press key information capable of being recognized by the computer; the movable ring microphone is used for being in charge of sound collection and converting voice input signals into electric signals; the audio wire is used for transmitting sound signalsconverted by the movable ring microphone to a sound card of the computer. The PTT hardware []detection mode with high reliability in wireless communication is applied to the tabletop microphone; the USB single key keyboard module is arranged inside the tabletop microphone; a user can realize high reliability during the real-time talkback of voice conference; the PTT function triggering by a mistake due to sound in ambient environment is avoided.

Description

technical field [0001] The invention relates to the technical field of communication between network platforms, in particular to a desktop microphone supporting a PTT hardware detection function. Background technique [0002] The real-time intercom function is a special form of voice conference. The speaker must grab the microphone to speak. Only after someone puts the microphone on, others can grab the microphone. At present, the PTT technology in wireless communication is used to realize microphone grabbing in real-time intercom, that is, when a user is detected to trigger PTT, it is determined who seizes the right to speak according to the user's priority. There are two commonly used PTT detection methods: one is through voice detection, that is, when the sound energy reaches a certain threshold value, the PTT function is triggered; the other is through hardware detection, that is, PTT is detected When the button is pressed, the PTT function is triggered. [0003] At pr...
