Sound Sensor ICs

A sound sensor IC is a small electronic component enabling the detection of sound. Sound sensor ICs are used for the detection of sound strength. When the sensor catches a sound, it processes an output signal voltage. The voltage is then transmitted to a microcontroller. RS offer a range of high-quality components from leading brands including Infineon.

How does a sound sensor module work?

Sound sensor ICs contain a very thin piece of metal called a diaphragm. When the metal vibrates by sound waves the vibration is converted by the sensor into an electrical signal.

Applications for Sound Sensors

Sound sensor ICs are used in a wide range of electronic circuit applications. Some of the most common areas are

• Active Noise Cancellation (ANC) headphones and earphones
• High-quality audio capturing
• Home automation
• IoT devices
• Smart speakers
• Microphones
