Strengthening the link between the real and the digital world
Responsive smart speaker designs that enable strong consumer engagement
Smart speakers are on the rise more than ever before and consumers are adopting the technology. However, as consumers grow accustomed to smart speaker technology, their expectations in performance are equally rising. This leads to ever-increasing requirements for smart speaker designers to get speakers on the market that hear better, sound better, are most-likely portable and overall react more intuitively to user needs. To enable responses to these requirements advanced semiconductor solutions are needed.
Taking a look at the different design considerations throughout the smart speaker architecture:
XENSIV? MEMS microphones represent a new benchmark in performance, and current audio chain limitations can be overcome. A product needs reliable sensitive microphones that suit the system. For a voice system to work well, good raw data from the microphone must be fed to the voice processing algorithms running on the main system. Infineon helps you to integrate fast and easy into your design so that you will get your product to market quickly. Testing schemes can be fulfilled without any delays.
If you want to integrate a voice-controlled user interface (VUI) into a product that previously lacked an audio interface or implement an appliance design e.g. in smart speakers, TVs, and home appliances, you know it is not without roadblocks.
Infineon helps you at the start of your concept and during your development process to engineer a successful digital audio assistant design with devices such as XENSIV? MEMS microphones.
Voice user interfaces need to be designed right from the beginning: it is critical for both consumer acceptance and integration of value-added services down the road. Interaction between a human and a digital assistant must become as intuitive and natural as possible.
Design products and devices that provide users with a best-in-class voice experience. For example the IM69D130 MEMS mic, ideal for applications that require low self-noise (high SNR) and distortion, a wide dynamic range, plus a high acoustic overload point.
Discover exceptional system benefits
Depending on the precise use case, highly sensitive Infineon MEMS microphones provide a range of system benefits.
- Whisper mode: Even softly spoken or whispered voice commands are picked up in more cases in systems with the Infineon mic. This improves user convenience and maximizes interaction.
- Multi-room and distance scenarios: As users become more at ease with voice technology, they expect more of their devices and seek natural interaction from across the room or in a different room.
- Regular voice: For devices with voice control to add significant convenience to everyday life, the technology must live up to its promise. Infineon mics lay a solid foundation for a great voice user experience.
Save space and costs with Infineon design solution
Once the voice is used, the design of products is affected too, as buttons on consumer products are reduced or even eliminated.
Our solutions also allow you to reduce the number of microphones in certain applications, saving BOM and space, and reducing the overall system cost.
At a similarly early stage, new technology is making its way to the stage – the Infineon radar sensors that have already made first appearances as speaker manufacturers are looking to increase the amount of intelligence within the speaker. For example, getting information on whether someone is around can help to turn on or off additional functionalities enabling a more intuitive interaction with the speaker, higher energy efficiency and enhanced privacy
Smart speakers are often used to listen to music but the audio quality of today’s speakers is often not satisfactory. To enable outstanding sound quality, the Infineon MERUS? provides amplifier solutions. Besides, consumers are looking for more flexibility in moving speakers, a requirement that can be met with the MERUS? amplifier solutions, which enable up to twice as long battery playback time. On top of that, designers have the option to design heatsink-free, enable filter less high performance, and thus simplify their design.
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 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.
Infineon 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 (5x6.5mm) and has extremely low power consumption. The technology has already been integrated into a smartphone for the first time ever to enable gesture control. With products launching onto the market this year, contact us today to learn how radar can help to make your speaker context-aware and enable true speaker innovation.
