In the era of smartphones, laptops, and tablets, built-in microphones have become an integral part of our daily lives. We use them to make phone calls, record videos, conduct online meetings, and even create content for social media. But have you ever stopped to think about the quality of these tiny sound-capturing devices? Are built-in microphones good enough to deliver crystal-clear audio, or do they leave much to be desired?
The Rise of Built-In Microphones
The rise of built-in microphones can be attributed to the increasing demand for convenience and portability. Gone are the days of carrying separate microphones and audio interfaces. Today, we expect our devices to come equipped with high-quality cameras, screens, and, of course, microphones.
The first built-in microphone appeared in the 1990s, when computer manufacturers started integrating them into laptops. These early models were basic and prone to picking up background noise, but they paved the way for future innovations.
How Built-In Microphones Work
Built-in microphones are typically condenser microphones, which use a diaphragm and a backplate to convert sound waves into electrical signals. The diaphragm vibrates when sound waves reach it, causing a change in capacitance between the diaphragm and the backplate. This change is then converted into an electrical signal, which is amplified and processed by the device’s audio circuitry.
There are two common types of built-in microphones:
Omni-Directional Microphones
Omni-directional microphones pick up sound from all directions, making them suitable for applications like video conferencing and phone calls. They are often used in laptops and tablets, where the microphone is usually located near the keyboard or on the lid.
Uni-Directional Microphones
Uni-directional microphones, on the other hand, focus on capturing sound from a specific direction, reducing background noise and ambient sound. They are commonly used in smartphones, where the microphone is often located near the bottom of the device.
