I want to buy a Bluetooth microphone to facilitate lectures, but I don't know what a Bluetooth megaphone is. Who can answer for me?
Which Bluetooth amplifier works?... I recommend a brand to you: Ning Da information. This brand is made in Ningbo, specializing in Bluetooth speech speakers. Our side also has teacher in use, the echo is good ~!Baidu company address, you can also buy on Taobao.
Most of the teaching amplifiers in the market are transmitted by high frequency radio waves, belonging to the old technology. Signal interference often occurs.So Bluetooth speakers are more expensive than regular speakers, about nine hundred.
Eh... As far as I know, Bluetooth speakers are emerging products, unlike the usual wireless speakers in the market.Bluetooth speakers, as the name suggests, are transmitted via Bluetooth signals. Digital sound quality, clear speech.It consists of two parts, one is the transmitter on the hand, the other is the receiver, usually the stereo (some old ones are separate from the host and the stereo). Teachers can amplify sounds by loudspeaker so as to give lectures conveniently.
