At present, the wirele✘✔ε∏ss microphone used in the educaγ&‍§tion market mainly use≥₽πs analog U-band and V-band t¶₩echnology, digital infπ∑∑₹rared technology and 2.4G£±☆ digital technology.
Its main scenario ap↑ plication is：
Method 1: In a classroom, fix a set  £¶of receivers (speaker amp×₩$lification), one or ≈•δtwo microphones;
Mode 2: Or only receiveγ© (loudspeaker amplificati ‍on), each teacher with a∏¥÷ separate wheat.

The first method is main φ∏±ly to use the teaching microphone under♥α the U-segment and V-segm¶"ent of the analog techno✔ • logy. Compared with the traditional ✘§microphone, the volume of wheat i±★™s large, which is prone to the prob ♥$©lems of serial frequen↓←$cy and mutual interference. It<> is difficult to modulate and mainta>§in. In the high-dens≈¥ity use environment of  >classroom, digital m•♠icrophone is more fl★•exible and easy to u§Ωse.

Digital infrared whea ↑✔t can basically meet the needs of§Ω$≈ teaching amplification, but ins✔πtallation must require hi<βgh directivity, wirin§£g more trouble.

2.4G digital wheat has always bee× n in the domestic market, but at presδ<ent there is only one X♠σiiSound in China who has ‌∑∑★the ability to do well↔¥γ  in anti-jamming and cα>₽λomprehensive stability. XiiSound schem§β♥∏e will make up for the ne‍Ω∑w standard of wireless audio ©♠♦bidirectional in theγ¶≈ domestic education ma→πrket and achieve a new lea​§♥p in the application of wi→₩​♦reless teaching wheat.
