A tiger 'and an antenna resemble the processed sound signal and a power supply m to provide the power required for the operation of the above components'. Generally, the power supply 225 is connected to two power sources to provide power J. And-the lead 23 is connected to the sound receiver body 22 'to supply power to the sound receiver 21 and to pass the received sound to the body 22. When in use, the body 22 is attached to a belt or a pocket, and the wire 23 = the body: The sound receiver 21 is clamped on the collar or clothes. This wireless microphone 2 # is used in classrooms, stages and other places. The wireless microphones sold by Meguro mostly use dry batteries as a source of power = source, due to the weight and volume of the dry battery itself, which makes it impossible to shrink the wireless microphone's product and weight, or as a wireless microphone 2 Need winding and other issues. There is also a variant of the attached wireless microphone 2 that uses a New Zealand mercury battery 'so that the sound receiver 2 丨 and the body 22 can be directly connected without wires' 'The attached wireless microphone 2 can be directly attached to the shirt' to It achieves the purpose of small size and small volume. However, the mercury battery has a short track record of obtaining power, has its own environmental protection problems, and needs to be replaced regularly. The disadvantage is that it is inconvenient to use. In fact, the circuit size required to achieve a wireless microphone is quite small, so as long as you avoid using the battery, you can avoid the above problems and increase the convenience of use.
