Helo, is that the wireless microphone is a transmitter?
If i build a wireless microphone, is that i also need to build a receiver?

the wireless microphone is a transcevier system,so it sure have receiver

how long is between your transcevier systems,if distance is not long ,you can select IrDa,or blutooth.

If you want to build a communication,you are sure to make a receiver

这英语真难看懂

maybe the wireless microphone is a transceiver.it is a transmitter,also is a receiver.

The wireless microphone is only a transmitter, if you set up a wireless microphone you should establish a receiver either.

a transmitter must have an antenna ,if you use bluetooth.or if you use IrDa,you can use a IrDa transmitter.

good good : microphone and receiver like brother
