About Infineon's soundbar solutions

Soundbars are used to generate crystal-clear yet powerful sound as a companion to flat-panel TVs. There are usually multiple speakers in a soundbar that can generate from basic stereo sound up to immersive 3D sound. Despite the long shape of soundbars, the usable PCB area for a sound bar system is actually quite limited. Hence, solution compactness, power density, high-efficiency operation, less heat, or idle power generation are very important features to keep in mind when designing a soundbar.?

Class D audio amplifiers

Infineon's versatile Class D amplifier solutions are ideal for soundbar designs. The MERUS? multilevel Class D amplifiers work with smaller output filters and have only 1/10th of idle power consumption compared to traditional Class D topology, which makes them perfect for tweeter channels in the soundbar. The MERUS? multi-chip-module Class D amplifier family has very low?RDS(on) and very high full-load efficiency, making them ideal to power subwoofer channels in the soundbar systems.?

Integrated Class D audio amplifiers
AC-DC power conversion

Infineon¡¯s latest generation of CoolSET? AC-DC integrated power stages in fixed-frequency and quasi-resonant switching schemes offer increased robustness and outstanding performance. These AC-DC solutions are enabled by the integration of the latest 700 V and 800 V CoolMOS? P7 superjunction MOSFET family in both DIP-7 and DSO-12 packages.

Wi-Fi + Bluetooth? combos

Infineon's 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. These solutions can be coupled with external MCUs for RTOS, along with Linux on application processors to implement a complete Wi-Fi + Bluetooth? system. We support our Wi-Fi + Bluetooth? customers through our global network of IoT partners using production-ready, fully certified AIROC? Wi-Fi + Bluetooth? combos modules based on both Linux and RTOS-based platforms.

Wireless connectivity
Touch control for your soundbars

The PSOC? 4000 family delivers the industry¡¯s best capacitive-sensing technology, CAPSENSE?, to implement buttons, sliders, and proximity sensors.

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 and 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.

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's 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.
