Generally, the price of a wireless collar microphone ranges from 100 yuan to 300 yuan. The specific price depends on its brand, sound quality, noise reduction effect and size. But if it is professional, it will be much more expensive, usually thousands or even thousands of dollars each.
Expand knowledge: what parameters should I pay attention to when buying a wireless collar microphone?
1, sensitivity
The higher the sensitivity, the stronger the horizontal gain output power of the collar microphone and the clearer the sound quality.
2. Recording and playback amplitude-frequency response
Frequency response refers to the description of the vibration range of audio bandwidth. The frequency response limit that the human ear can receive is about 20 Hz-20 Hz. In general, the smoother and wider the frequency response of a good collar microphone, the better the vocal recording effect will be.
3, signal-to-noise ratio
Signal to noise ratio refers to the ratio of signal output power to noise power. The greater the signal-to-noise ratio, the less noise and murmur in the signal, and the clearer the sound quality. However, the signal-to-noise ratio of collar microphones is generally not too high. When shooting outdoors, it is best to use a windproof sponge to reduce the pickup of environmental sounds.
4. Directionality
Directivity is the general term for the sensitivity of microphone in different pickup directions. At present, the collar-clip microphone on the market has two directivity: omnidirectional and cardioid. Omni-directional pickup is relatively wide, and the sound source around the microphone can be picked up 360 degrees. The shortcomings are also obvious. For example, in a noisy environment, the microphone will pick up the surrounding noise and affect the whole recording effect. Heart-shaped pointing to the sound source most suitable for the front of the pickup microphone, insensitive to the sound sources on both sides and behind, suitable for fixed-angle recording. When choosing, you can mainly choose according to your own needs.
