When to use a lavalier microphone ?
Many of the friends have lavalier wireless microphone in their hands. Similarly, they often suffer headaches for lavalier microphones. Headaches are mainly concentrated in the use of lavalier microphone, the volume can not push up, slightly push a little bigger, it is prone to whistling. If an equalizer is used to pull the howling point, it will not be howling, and the microphone's voice will not be heard, but will be thin and scattered.
Why does this happen? First of all, an important reason why the microphone is whistling is that the microphone can receive the sound from the speaker. As long as the microphone can receive the sound from the speaker, the path for positive feedback is established. As long as the path of positive feedback is available, as long as the sound from the speakers is large enough, positive feedback self-excited, that is, howling will occur.
See here, many friends will ask: Why is the lavalier microphone on the stage, behind the speakers, but also did not open to hear, or easily cause howling?
BY-LM400 Dual-Lavalier Microphone
The BOYA BY-LM400 is a dual-lavalier microphone is designed for recording interviews. With 3.5mm(1/8") TRRS connector, it works for iPhone, Ipad and most of Android devices.
First of all, the sound produced by the speakers is high school and low-frequency, and the transmission of higher-frequency sounds is directional, while the sounds of lower-frequency sounds are poorly-directed. Sounds lower than 250 Hz can basically be said to have no directivity in transmission. So, although the microphone is on the stage behind the speaker, the lower frequency sound emitted by the speaker still radiates to the stage and is received by the microphone.
So why are the lavalier mics more likely to yell than the dynamic mics? Well, when you use the lavalier microphone, have you noticed the directionality of the lavalier microphone you have on hand? I believe many people have not noticed this problem. The mic's microphone head directionality is also omni-directional, heart-shaped, and super-cardioid. If you buy an omnidirectional microphone, you can only say that it is a tragedy! The howling will always be with you!
