What has been changing in recent years is the web live broadcast platform. Whether you are a professional singer or a business anchor, you need a logistics microphone with clean sound and minimal environmental noise, or because the anchor wants to show a beautiful voice in front of the live audience . At this time, the requirements for microphones are relatively high, making condenser wireless microphones more and more popular. The editor introduced several wireless microphones used here, which can be roughly divided into the following categories;
The dynamic wireless microphone uses a coil to cut the magnetic induction line in a magnetic field, and the sound signal is converted into an electrical signal by the current generated by it. Since there is a diaphragm inside the dynamic microphone, the thickness of the diaphragm cannot be guaranteed to be thin enough, so the performance in the treble range is relatively ordinary, and the response to the sound of relatively small volume is somewhat poor.
Although the cost of condenser wireless microphones is higher, condenser microphones can record more harmonic elements and details than dynamic microphones, and are also superior to dynamic microphones in terms of high-frequency extension and low-frequency response. It is more suitable for recording radio dramas, dubbing, blogs and other places that do not receive background noise as much as possible, so it is generally used in professional recording studios.
Dynamic wireless microphones are not all disadvantages. First of all, it is cheaper and easier to operate, lowering the barrier to purchase. And the performance is very stable, and the directivity of the radio reception is also very good. Where there are no special requirements for sound quality, such as KTV, the microphone is dynamic.
If you have higher requirements for sound quality and sufficient funds, condenser microphones are a good choice. The core component of a condenser wireless microphone is composed of two layers of ultra-thin metal films. When the sound causes the metal film to vibrate, the capacitance changes, resulting in a measurable signal. However, condenser microphones generally need to be connected to a 48V phantom power supply, and also need to be connected to an amplifier or mixer to work.
