What Is Conference Call Microphone?

A conference call microphone is a specialized microphone designed to capture sound clearly from multiple speakers in a conference room or during remote meetings. It is optimized for group discussions, allowing participants to speak naturally without having to lean towards the microphone. These microphones are often integrated into conferencing systems and are commonly used in video conferencing, conference calls, and hybrid work environments.

Key features of conference call microphones include:

• 360-degree coverage: Captures sound from all directions, making it ideal for group settings.

• Noise cancellation: Reduces background noise for clearer voice transmission.

• Echo reduction: Minimizes audio feedback and echo, ensuring smooth communication.

• Daisy-chaining: Some models allow multiple microphones to be linked for large rooms.

Popular examples of conference call microphones include devices like the Yealink CPW90 wireless microphone. These microphones can be standalone devices or part of a larger audio-visual system, designed to enhance collaboration in both small and large spaces.

Conference call microphones come in various types, each designed to suit different environments and meeting sizes. The main types include:

1. Omnidirectional ceiling Microphones 

• Description: These capture sound from all directions (360-degree coverage).

• Use Case: Ideal for small to medium-sized conference rooms where participants are seated around the microphone.

• Example: Yealink CM20(AI-Powered Beamforming Ceiling Microphone).

2. Unidirectional Microphones

• Description: Capture sound primarily from one direction, reducing background noise.

• Use Case: Best for individual speakers or focused discussions in larger, noisier environments.

3. Boundary Microphones

• Description: These flat microphones are placed on a surface, capturing sound across a wide area, often using a reflective surface.

• Use Case: Suitable for large conference tables or rooms with several participants.

4. Wireless Conference Microphones

• Description: Offer the flexibility to move the microphone around without cables.

• Use Case: Ideal for dynamic meetings where participants move around or in larger rooms with multiple people.

• Example: Yealink VCM36.

5. Daisy-chainable Microphones

• Description: Allow multiple microphones to be linked together to cover larger rooms or extended meeting spaces.

• Use Case: Useful for large conference rooms or auditoriums where sound capture from multiple areas is needed.

• Example: Yealink CMKit-121 （ Yealink audio ceiling solution）

Each type is tailored to different conferencing needs, ensuring clear audio transmission and improving meeting efficiency.
