影片描述：I try to develop an portable outdoor Alexa-enabled speaker, letting users take Alexa anywhere. I call it a “the 3rd-generation Echo”. The 3rd-generation Echo with a slot for an LTE SIM card connect to the voice-controlled intelligent personal assistant service Alexa, which is capable of voice interaction, music playback, making to-do lists, setting alarms, streaming podcasts, playing audiobooks, and providing weather, traffic and other real-time information. It can also control several smart devices acting as a home automation hub, allowing you to use it as an portable outdoor Alexa-enabled speaker, letting you take Alexa anywhere. So I made a conceptual product movie for reference.我同意以「創用CC 姓名標示-相同方式分享 3.0 國際版（CC BY-SA 3.0）」這一開放授權釋出該作品。
