Bosch Sensortec GmbH products

The BMA580 is an advanced voice activity detection accelerometer from Bosch Sensortec, designed for use in highly compact devices such as hearables. Measuring just 1.2 x 0.8 x 0.55 mm³, it is the world's smallest accelerometer with built-in speech processing capabilities through bone conduction. This sensor features unique power mode options, optimizing power consumption by ensuring the microphone activates only for necessary voice detection. Its minimal size aids in easy integration into space-constrained devices, enhancing the functionality of hearable products by offering reliable voice detection and user interaction. The BMA580 is suitable for innovative applications where space and efficiency are critical, serving as a significant component in the development of next-generation auditory and communication devices.

The BMA550 by Bosch Sensortec is an advanced acceleration-based body sound sensor, specifically designed for hearable devices. It addresses challenges in environments with high ambient noise, effectively enhancing voice clarity by filtering out unwanted sound. This accelerometer features significantly reduced noise levels, ranging from 5-7 times lower than typical accelerometers, offering a clear advantage in sound detection. With a low power consumption design, the BMA550 supports a high data rate of up to 48 kHz, allowing for low latency applications. The sensor's compact form factor allows for easy integration into various devices. Additionally, it supports continuous usage through always-on low-power speech processing, making it ideal for perpetual operations in devices like smartwatches, wristbands, and smart clothing. This component plays a crucial role in enhancing voice-based interactions, enabling smooth communication in noisy environments.
