This study of a smart home speaker with intercom function was developed in 2018. We have developed this product from the first sketch to the injection mold and the certification according to all European regulations for EMC and electrical safety,

To implement privacy-by-design, all the audio data that the microphone picks up is only stored locally on the device in RAM and is also evaluated there and not transmitted to the cloud. This has the additional advantage that the device can work without Internet access.

Specifically, we are responsible for

• CAD creation and 3D printing
• Prototyping of the plastic body with fabric cover
• Individual electronics development (component selection, EMC-compliant design)
• Firmware development with own implementation of an ECC encryption protocol for data transmission
• Development of a closing mechanism for the optional 230V plug
• Accompanying the safety and EMC tests
