About smart speaker designs

Once a novelty in households, smart speakers are becoming increasingly commonplace. Rising user expectations accompany this rapid growth. However, frustration with devices that do not understand or hear commands leads to lower user adoption. Consequently, growth rates for smart speakers are failing to reach their full potential. Components such as MEMS microphones, touch controllers, and new technologies such as radar are vital in improving the user experience in the smart speaker segment. For example, new technology is making its way to the stage, like the Infineon radar sensors that have already made first appearances as speaker manufacturers are looking to increase the amount of intelligence within the speaker. You can use this in many scenarios, such as gathering information on whether someone is nearby can help to turn on or off additional functionalities, enabling more intuitive interaction with the speaker, higher energy efficiency, and enhanced privacy. 

Infineon has long-standing expertise in sensors, connectivity, and power solutions that fulfill the consumer market requirements in terms of outstanding performance, reliability, and energy efficiency.

Infineon's smart speaker evaluation kit

The Infineon smart speaker evaluation kit, jointly developed with our preferred partner Sugr, demonstrates Infineon’s comprehensive smart speaker application portfolio and Sugr’s algorithm know-how. It is the perfect start to test and evaluate the performance of all components for a state-of-the-art smart speaker design quickly and simply. The evaluation kit offers an all-in-one evaluation platform for all the functional blocks of a smart speaker design and reduces your time to market. Additionally, our products enable innovative features such as predictive maintenance, vital sensing, voice control, and outstanding audio.

Radar and SMPS solutions

Infineon's XENSIV™ 60 GHz radar technology enables a new form of interaction between users and devices. It enables sensing presence and movement of people with high precision. The chip is very small (5x6.5 mm) and has extremely low power consumption. The technology has already been integrated into a smartphone for the first time ever to enable gesture control.

In addition, speakers need to be powered in an efficient and space-saving manner – no consumer is happy with a speaker power supply that distracts from the elegantly designed main device. Alternatively, even worse is a power supply that destroys the main speaker due to overvoltage. Efficient and robust MOSFETs and drivers are therefore a key requirement and can easily be met with Infineon’s long expertise in power systems design.

Audio input for voice-user interface (VUI)

Infineon's XENSIV™ MEMS microphones offer exceptional performance, addressing limitations in the audio chain. They provide reliable and sensitive audio input for voice systems, ensuring high-quality data for voice processing algorithms. Infineon assists in easy integration and fast time to market, supporting the development of successful digital audio assistant designs. These microphones are ideal for implementing voice-controlled user interfaces in various products, such as smart speakers, TVs, and home appliances. They enable natural and intuitive interaction between users and digital assistants, delivering a best-in-class voice experience. Infineon MEMS microphones excel in picking up softly spoken or whispered voice commands, accommodating multi-room scenarios, and enhancing regular voice interactions. Furthermore, Infineon's design solutions help reduce costs and save space by eliminating the need for buttons and minimizing the number of microphones required in certain applications. Overall, Infineon empowers users to create innovative and cost-effective voice-controlled products with exceptional system benefits.

CIRRENT™ product analytics and Wi-Fi + Bluetooth® combos

CIRRENT™ product analytics offers cloud software solutions to enhance the performance, reliability, and connectivity of IoT products. CIRRENT™ IoT Network Intelligence (INI) enables data-driven product development by securely reporting real-time data from IoT devices to the cloud. It empowers product teams to improve user experience, decrease returns, and increase sales. CIRRENT™ Mobile App Intelligence (MAI) provides insights into Wi-Fi onboarding and mobile app usage, leading to improved connectivity rates and app reviews. Both solutions offer real-time access and analytics through the CIRRENT™ console, enabling product and engineering teams to address customer issues more effectively. 

In addition, our AIROC™ Wi-Fi + Bluetooth® combos integrate IEEE 802.11a/b/g/n/ac WLAN and Bluetooth® in a single-chip solution to enable small-form-factor IoT designs. Combo solutions are available for both 1x1 SISO with up to 433 Mbps PHY data rates and 2x2 MIMO with up to 867 Mbps PHY data rates. We support our Wi-Fi + Bluetooth® customers through our global IoT partners using production-ready, fully certified AIROC™ Wi-Fi + Bluetooth® combos modules based on Linux and RTOS-based platforms.

Implementing touch control in your smart speaker design

The PSOC™ 4000 family delivers the industry’s best capacitive-sensing technology, CAPSENSE™, to implement buttons, sliders, and proximity sensors for touch control.

We recommend using either PSOC™ 4000S or PSOC™ 4100S, depending on how many I/Os or touch buttons are needed. The PSOC™ 4000 family is a cost-optimized, entry-level family of Arm® Cortex®-M0 and M0+ microcontrollers. The PSOC™ 4100 family adds intelligent analog integration through programmable analog blocks. Programmable analog blocks include analog-to-digital converters (ADCs), digital-to-analog converters (DACs), low-power comparators, and operational amplifiers (opamps). The PSOC™ 4100BL includes an integrated Bluetooth® low Energy radio & subsystem.

If you require a metallic overlay for an HMI solution, PSOC™ 4700S with noise-immune, inductive- and capacitive-sensing user interface is the best choice. The PSOC™ 4700 family adds advanced sensing technologies to sense anything including advanced capacitive sensing, inductive sensing, heart-rate sensing, and more. These advanced sensing technologies leverage specialized analog blocks in the PSOC™ 4 portfolios to deliver innovative solutions to next-generation designs.
