Teardown TechnologyA quick look inside the Apple Homepod Mini design wins, but is there a secret part waiting to be intialized?
苹果HomePod Mini A2374 is a voice-interactive smart speaker with Siri assistant. It features four microphones delivered by Goertekand a capacitive touch pad on the top of the speaker (supported by sensor controllers from Analog Devices) that allows control of the device using different tap patterns.
The smart speaker is equipped with a single active speaker and dual passive radiators. The U1 ultra-wideband chip allows for a user with another U1 equipped device with Bluetooth turned on (such as an iPhone) to send audio to the speaker using Apple's handoff feature. The Thread connectivity allows the HomePod to communicate with other Thread-enabled smart HomeKitdevices.
Apple has the most design wins for the Apple HomePod Mini A2374. Apple supplied the 64-bit dual-core S5 APL1W82 application processor, which was introduced in the Apple Watch Series 5 in 2019. Apple also used its own 338S00553-A0/D2482A power management chip, developed in cooperation with Dialog Semiconductor, and 339M00117 WiFi/Bluetooth solution.
Supporting memory consists of 1 GB mobile LPDDR4 SDRAM and 32 GB 3D NAND Flash, integrated in a single package from SK Hynix.
Three separate antennas connected to modules delivered by Apple, USI, and Nordic Semiconductor support WiFi 802.11n/Bluetooth 5.0, UWB, and Thread connectivity, respectively. The audio amplifier and two capacitance sensor controllers were provided by Analog Devices.

德州仪器offers the HDC2010 low power humidity and temperature digital sensor
Although not active as of yet, the Apple HomePod Mini has the Texas Instruments HDC2010 in place. Unlike the Texas Instruments TMP112B temperature sensor we found in the Amazon Echo Generation 4, the HDC2010 is both an integrated humidity and temperature sensor rated to have a 2% humidity reading accuracy directly from the factory.
“德州仪器HDC2010是一种集成的湿度和温度传感器，可提供高精度测量，在超紧凑型晶片级芯片秤包（WLCSP）中具有非常低的功耗。HDC2010的传感元件放置在底部设备，使HDC2010对污垢，灰尘和其他环境污染物更加强大。基于电容式传感器包括新的集成数字特征和加热元件，以消散冷凝和湿度。HDC2010数字功能包括可编程中断阈值以提供警报/系统唤醒而不需要微控制器持续监控系统。这将与可编程采样间隔结合使用，低固有功耗和对1.8 V电源电压的支持，使HDC2010非常适合电池供电的系统。“1Source:德州仪器

According toBNN Bloomberg,"If Apple eventually enables the sensor, it would bolster a smart-home strategy that has sometimes lacked focus and trailed those of rivals. Amazon.com Inc.’s latest Echo speakers have temperature sensors, while Google’s Nest sells sensors that can be placed around homes and connect to its thermostats to adjust the temperature of each room."
