In the use of smart homes, most people are curious about how it completes our instructions? This is about the microphone pickup head, which is more commonly known as the microphone head or microphone core. Its small body contains a lot of energy, and through precise sound sensing technology, it converts sound waves into electrical signals, giving smart homes a pair of sensitive ears, waiting to execute the commands we give them. Among them, omnidirectional microphones, single directional microphones, and polar microphones play their roles in different homes with their unique advantages.
Omnidirectional Microphone
The first thing to introduce is the omnidirectional microphone head, which adopts a 360° omnidirectional sound pickup design. It can capture the sound emitted from all directions in the space, so it is more commonly used in smart speakers, home control, and other devices. When we issue the command to "turn on the living room light" at any location in our home, devices equipped with omnidirectional microphones can quickly respond.
Single Directional Microphone
The next thing to introduce is the single directional microphone, which is exactly the opposite of the full directional microphone. Because it can only recognize sounds from specific directions, it can recognize sounds from specific directions more clearly. In response to this feature, we will use it in scenarios such as smart access control and conference terminals that require precise sound pickup. When a visitor is talking to the smart doorbell, even if the environment is noisy, it is not a big problem.
Electret Microphone
As the main user of smart devices, the electret microphone head has become a "standard configuration" for smart homes for a reason. It has high sensitivity, wide frequency response, and low power consumption, and is widely used in small devices such as smart switches and thermostats. For example, an air conditioning controller equipped with an electret microphone can accurately recognize voice commands within 3 meters and obey our commands.
