Microphone modules are compact units that integrate a microphone element with essential circuitry, such as decoupling capacitors, connectors or contact pads, into a single package. They simplify the integration of audio capture into devices by providing a ready-to-use solution. Commonly used in smartphones, voice assistants, and IoT devices, these modules offer ease of integration and consistent performance, accelerating product development and enhancing audio functionality.
