关于
智能扬声器曾经是家庭中的新奇事物,如今却变得越来越普遍。随着热度不断上升,用户对智能扬声器的期望也不断提高。然而,如果设备听不懂或听不到指令,用户满意度会降低,采用率也会随之降低。因此,智能扬声器的用户增长率还有上升空间。MEMS 麦克风、触控控制器和雷达等新技术等组件对于改善智能扬声器领域的用户体验至关重要。新技术正在崭露头角。例如,英飞凌雷达传感器首次亮相于扬声器制造商的智能扬声器产品中。这种传感器可在许多场景中用到,比如根据是否有人在附近,开关一些功能,让扬声器的交互更自然,节能又保护隐私。
英飞凌在传感器、连接和电源解决方案方面拥有深厚的专业知识,能够满足消费者市场对性能、可靠性和能效的高标准需求。
英飞凌与首选合作伙伴 Sugr 共同开发的智能扬声器评估套件展示了英飞凌全面的智能扬声器应用组合和 Sugr 的专业算法。这是对所有组件性能的快速且简单的测试与评估,是设计最先进的智能扬声器的完美开端。该评估套件为智能扬声器设计的所有功能块提供了一个一体化评估平台,可缩短您的上市时间。此外,我们的产品还具有创新功能,例如预测性维护、生命传感、语音控制和出色的音频。
探索我们的评估套件,亲身体验我们的多合一套装,缩短产品上市时间。
英飞凌的 XENSIV™ 60 GHz 雷达技术打造了新形态的人机交互。它可以高精度感知人员的存在和移动。该芯片的尺寸非常小(5x6.5 mm),功耗极低。该技术已首次集成到智能手机中,以实现手势控制。
此外,扬声器需要以高效且节省空间的方式供电——对于会影响扬声器主设备美观度的电源设计,任何消费者都不会满意。亦或者电源由于过压而损坏了主扬声器,这一点更是糟糕。因此,高效、稳健的 MOSFET 和驱动器是关键。而英飞凌在电源系统设计方面具备深厚的专业知识,可以轻松满足这一要求。
英飞凌的 XENSIV™ MEMS 麦克风具备卓越的性能,消除了音频链中的局限性。这款麦克风为语音系统提供可靠而灵敏的音频输入,确保语音处理算法可接收到高质量的数据。英飞凌帮助简化集成和加快上市,支持开发成功的数字音频助理。这些麦克风非常适合用于智能音箱、电视和家电等各种产品的语音控制界面。它们支持用户和数字助理之间进行自然、直观的交互,提供一流的语音体验。英飞凌的 MEMS 麦克风能准确捕捉轻声或低语的语音命令,适应多房间场景,增强常规语音交互。此外,英飞凌的设计解决方案能省去按钮,减少某些应用需要的麦克风数量,节省成本和空间。总体而言,英飞凌使用户能够设计出具有卓越系统优势、创新、经济的语音控制产品。
CIRRENT™ 产品分析提供云软件解决方案,让物联网产品更高效、可靠、连通。CIRRENT™ 物联网网络智能(INI)可以将来自物联网设备的实时数据安全地报告到云,以实现数据驱动的产品开发。它能够使产品团队改善用户体验、减少回报并增加销售额。CIRRENT™ 移动应用程序智能(MAI)可以分析Wi-Fi上线和移动应用使用情况,提高以连接率和应用评价。两种解决方案都通过 CIRRENT™ 控制台提供实时访问和分析,帮助产品和工程团队更有效地解决客户问题。
此外,我们的 AIROC™ Wi-Fi + Bluetooth® 组合集成了 IEEE 802.11a/b/g/n/ac WLAN 和 Bluetooth®,支持小尺寸物联网设计。组合解决方案可用于 1x1 SISO(PHY 数据传输率高达 433 Mbps)和 2x2 MIMO(PHY 数据传输率高达 867 Mbps)。我们有遍及全球的物联网合作伙伴,使用基于 Linux 和 RTOS 平台、可直接投入生产并经过全面认证的 AIROC™ Wi-Fi + Bluooth® combos 组合模块,为我们的 Wi-Fi + Bluooth® 客户提供支持。
PSOC™ 4000 系列提供业界最佳的电容传感技术 CAPSENSE™,用于实现按钮、滑块和接近传感器。
我们建议使用 PSOC™ 4000S 或 PSOC™ 4100S,具体取决于所需的 I/O 或触摸按钮数量。PSOC™ 4000 系列是一个面向成本优化的入门级产品系列,基于 Arm® Cortex®-M0 和 M0+ 内核的微控制器。PSOC™ 4100 系列通过可编程模拟模块实现了智能模拟集成。可编程模拟模块包括模数转换器(ADC)、数模转换器(DAC)、低功耗比较器和运算放大器(opamps)。PSOC™ 4100BL 集成了一个低能耗 Bluetooth® 无线电和子系统。
PSOC™ 4700S 采用了抗噪声、电感和电容感应用户界面技术。若您需要在 HMI 解决方案中使用金属覆盖层,PSOC™ 4700S 是最佳的选择。PSOC™ 4700 系列采用了先进的传感技术,可感知任何内容,包括高级电容传感、电感传感、心率传感等。这些先进的传感技术集成了 PSOC™ 4 产品组合中的专用模拟模块,为下一代设计提供了创新型解决方案。
