MEMS MICROPHONES
Advanced audio technology for modern devices
MEMS microphones (Micro-Electro-Mechanical Systems) are a groundbreaking technology in microphone development that combines the advantages of microelectronics and micromechanics. These microphones consist of a small, movable diaphragm and a fixed electrode, which together act as a capacitor. When sound waves hit the diaphragm, they create a change in capacitance that is converted into an electrical signal representing the sound waves.
An outstanding feature of MEMS microphones is their miniaturization. Compared to conventional microphones, they are significantly smaller and can be easily integrated into compact devices. This small size makes MEMS microphones ideal for use in smartphones, wearables, tablets, smart home devices and many other portable electronic devices.
Key Features and Advantages
Robust Performance
Another important advantage of MEMS microphones is their robustness. They are less susceptible to external disturbances such as humidity and temperature, which ensures their performance even in demanding environments. They are also resistant to electromagnetic interference (EMI), which minimizes susceptibility to interference in modern, densely packed electronic systems.
Technical Excellence
Technically, MEMS microphones offer high sensitivity, a wide frequency response and low distortion, providing excellent audio quality. They often work with digital interfaces, such as Pulse Density Modulation (PDM), which facilitates integration into digital signal processing systems. They also have low power consumption, which makes their use in devices with limited battery life particularly advantageous.
In practice, MEMS microphones are used in a variety of applications. They are used in smartphones for voice control, in headphones for better voice recording, in smart home products for voice assistants and in portable audio recording devices. MEMS microphones are also used in the automotive industry, in aviation and in medical devices due to their reliability and small size.
In summary, thanks to their compact design, robust properties and high performance, MEMS microphones represent a key technology for modern devices and enable the development of new, more powerful products.
