A wireless microphone, or cordless microphone, is a microphone without a physical cable connecting it directly to the sound recording or amplifying equipment with which it is associated. Also known as a radio microphone, it has a small, battery-powered radio transmitter in the microphone body, which transmits the audio signal from the microphone by radio waves to a nearby receiver unit, which recovers the audio. The other audio equipment is connected to the receiver unit by cable. In one type the transmitter is contained within the handheld microphone body. In another type the transmitter is contained within a separate unit called a “bodypack”, usually clipped to the user’s belt or concealed under his clothes. The bodypack is connected by wire to a "lavalier microphone" or "lav" (a small microphone clipped to the user's lapel), a headset or earset microphone, or another wired microphone. Most bodypack designs also support a wired instrument connection (e.g., to a guitar). Wireless microphones are widely used in the entertainment industry, television broadcasting, and public speaking to allow public speakers, interviewers, performers, and entertainers to move about freely while using a microphone without requiring a cable attached to the microphone.

High density DECT based wireless audio system
A wireless communication method and protocol for wireless RF transmission of audio data from a plurality of wireless RF devices (portable parts PP) to a wireless RF receiver device (fixed part FP) using a full slot DECT protocol. The FP broadcasts in each frame, a multiplex of control information to the plurality of PPs. The PPs receive the multiplex of control information, and extract control information intended for each individual PP from the multiplex of control information. Preferably, the PPs are synchronized to transmit audio data in respective time slots covering both time slots in first and second half of the frame. This allows a high number of PPs to be connected to one FP still at a high audio quality with low latency, since both the normal uplink and downlink parts of the DECT frame are used for audio data transmission. This allows the method to be used for a conference call system of a high number of wireless microphone devices, or a live performance wireless microphone and / or musical instrument sound system or the like.

A method and apparatus for transmitting an audio signal of a multi-band multiplex wireless microphone
This invention discloses a method and apparatus for transmitting audio signals using a multi-band multiplexed wireless microphone. The method includes: converting an audio signal into a radio frequency modulated signal and performing linear power amplification to obtain a wideband radio frequency signal; then, directionally guiding the wideband radio frequency signal into a target filtering path corresponding to a preset frequency band; obtaining a clean target frequency band radio frequency signal through narrowband constraint filtering of a bandpass filter within the path; finally, converging the signal into a single path and transmitting it to a receiving end based on an antenna matching its preset frequency band. This invention proposes a method and apparatus for transmitting audio signals using a multi-band multiplexed wireless microphone. By using linear power amplification to avoid harmonic spurious signals generated during high-power output, directionally guiding the wideband signal to a path corresponding to a preset frequency band and filtering out spurious signals through narrowband constraint filtering of a bandpass filter, and combining this with an antenna to improve transmission efficiency, it can solve the problem of incompatibility between spurious signal suppression and antenna efficiency under high-power output of ultra-wideband wireless microphones.
