Head mounted microphone features:
Like a lavalier microphone, the sound source of a headset microphone is speech and singing. Unnecessary sound sources include other people's voices, instrument sounds, environmental noise, and sound from sound system speakers.
Most head mounted microphones are condenser microphones because of their small size and high sound. Dynamic microphones are generally used for speeches, if larger size is not a problem. Regardless of the type of microphone, the increase in frequency response high frequency is to enhance the sense of presence when picking up human voices at close range. Omnidirectional head mounted microphones are suitable for most situations, especially when the microphone cannot be in front of the mouth. In high noise environments, choosing a single directional microphone for pickup is more suitable as it can control the voice generated by the high volume monitoring speaker.
The correct use of a single finger head mounted microphone should be placed directly in front of the mouth, or at the mouth and facing the mouth. For single directional head mounted microphones, a windproof cover is necessary. The head mounted microphone design brings the microphone components very close to the sound source. Balanced low impedance output is more suitable for wired microphones, while head mounted microphones are typically used in wireless applications. If that's the case, both impedance and continuity must be applicable to the wireless system. For condenser microphones, the waist bag transmitter provides a bias voltage for the microphone.
There are many different headgear designs available. Most microphones come with a headband and wireframe so they can be worn on the head, while a few small microphones can be clipped onto the ears.
In all cases, the microphone is located at the end of a miniature microphone rod or has a flexible and bendable handle that can be adjusted to a position close to the mouth. Omnidirectional microphones can be placed slightly behind or next to the mouth, while single directional microphones should be placed in front of or to the side of the mouth, facing directly towards the mouth.
Compared to lavalier microphones, the biggest advantage of head mounted microphones is their higher feedback gain, which makes them less prone to whistling and maintains a constant volume.
The gain before feedback can be increased by up to 15-20 decibels. This is entirely because it is closer to the mouth than a lavalier microphone. In this regard, head mounted microphones can almost compete with handheld microphones. Furthermore, compared to lavalier microphones, the consistent loudness is due to the fact that no matter how the user rotates their head, the distance between the head mounted microphone and the mouth remains consistent.
