Millet also joined the smart speaker war, it can do better?

Xiaomi made a bold move into the world of smart speakers, unveiling a new device at their conference on July 26th. Alongside the introduction of the Xiaomi 5X smartphone, which features a dual-camera setup, Xiaomi also debuted its smart speaker priced at just 299 yuan. To activate this speaker, users need to call out “Little Love.” Visually, the design of Xiaomi’s AI speaker is quite unique, resembling a miniature version of their air purifier with an eccentric cylindrical shape. Positioned on the top are four control buttons and a microphone ring array. A light blue ring light is also located at the top, used to indicate wake-up and recognition status. Most smart speakers on the market today adopt a similar columnar structure, which offers several advantages. The cylindrical shape provides ample internal space for a 360-degree sound output from the built-in speaker. Additionally, the microphone placement ensures it remains unobstructed at the top, minimizing any interference from the bottom source during speech recognition. This particular speaker project was spearheaded by Xiaomi’s Exploration Lab, established earlier last year, which provides technical support for voice recognition and other AI functionalities. The “Water Drop Project,” an AI platform developed by the Exploration Lab, was officially launched in May this year. It aims to offer free access to voice recognition and multiple API data interfaces for third-party developers. These interfaces allow manufacturers to integrate their own smart home devices or services with Xiaomi’s ecosystem. Currently, Xiaomi's voice services support a wide range of functions including air purifiers, robotic vacuum cleaners, smart lighting systems, rice cookers, security cameras, smart sockets, wall switches, and more. The diversity of products within Xiaomi’s ecological chain is gradually expanding, providing a significant advantage for their AI speakers in the future. Xiaomi’s smart speaker focuses on more than just playing music—it emphasizes the ability to control various smart home devices through voice commands. However, the growing popularity of smart home products remains limited, and many companies still operate within closed ecosystems. As a result, most smart speaker products, including Xiaomi’s, Alibaba’s “Tmall Genie,” Google Home, and Amazon’s Echo, are primarily limited to functioning as voice-controlled speakers. Despite these limitations, Xiaomi’s strategic focus on integrating its smart home ecosystem could give it an edge over competitors in the long run. However, the success of this approach ultimately depends on consumers adopting and purchasing compatible products within the Xiaomi ecosystem.

What is Car Ethernet
Car Ethernet is a new local area network technology that uses Ethernet to connect the electronic unit in the car. Unlike traditional Ethernet, which uses 4 unshielded twisted pair cables, car Ethernet can achieve a transmission rate of 100Mbit/s or even 1Gbit/s on a single pair of unshielded twisted pair cables. At the same time, it also meets the requirements of the automotive industry for high reliability, low electromagnetic radiation, low power consumption, bandwidth allocation, low latency and synchronous real-time. The physical layer of on-board Ethernet uses BroadRReach technology, and BroadR-Reach's physical layer (PHY) technology has been standardized by the One-pair Ethernet Alliance (OPEN). Therefore, it is sometimes called Broad RReach (BRR) or OABR (Open Alliance BroadR-Reach). The MAC layer of vehicle Ethernet adopts the IEEE 802.3 interface standard and seamlessly supports widely used high-level network protocols (such as TCP/IP) without any adaptation.

On-board Ethernet protocol architecture
Vehicle-borne Ethernet and its supported upper-layer protocol architecture are shown in Figure 1. Vehicle-borne Ethernet mainly involves OSI layer 1 and Layer 2 technologies, while vehicle-borne Ethernet also supports AVB, TCP/IP, DOIP, SOME/IP and other protocols or application forms.

On-board Ethernet framework
Among them, AVB is an extension of traditional Ethernet functions, which enhances the real-time performance of traditional Ethernet audio and video transmission by adding precise clock synchronization, bandwidth reservation and other protocols, and is a network audio and video real-time transmission technology with great development potential. SOME/IP (Scalable Service-Oriented MiddlewarE on IP) specifies the video communication interface requirements for vehicle camera applications, which can be applied to the field of vehicle cameras, and realizes the mode control of driver assistance cameras through apis.

As an extension of AVB protocol, Time-Sensitive Networking (TSN) introduces related technologies of time-triggered Ethernet, which can efficiently realize the transmission of automotive control information. In addition, the on-board Ethernet of the 1Gbit communication standard also supports Power Over Ethernet (POE) function and Energy-Efficient Ethernet (EEE) function. The POE function provides power for connected terminal devices while transmitting data through twisted pair cables, eliminating the need to connect external power cables to terminals and reducing the complexity of power supply.

On-board Ethernet standardization
In terms of in-vehicle Ethernet standardization, the IEEE802.3 and IEEE802.1 working groups, AUTOSAR, the OPEN Alliance and the AVnu Alliance have played a major role in promoting it.
The IEEE802.3 local area network standard represents the mainstream Ethernet standard in the industry, and the on-board Ethernet technology is developed on the basis of IEEE802.3, so the IEEE is currently the most important international standardization body for on-board Ethernet. In order to meet the requirements of the car, it involves the development of a number of new specifications and the revision of the original specifications within the two working groups of IEEE802 and 802.1, including PHY specifications, AVB specifications, and single-wire to data line power supply. In addition, AVB related to AV transmission, timing synchronization and other specifications also need to be standardized by other technical committees of IEEE, such as IEEE1722 and IEEE1588.

OPEN Alliance
The OPEN Industry Alliance was launched in November 2011 by Broadcom, NXP, and BMW to promote the application of Ethernet-based technology standards to in-car connectivity. The main standardization goal is to develop a 100Mbit/s BroadR-R physical layer standard and develop OPEN interoperability requirements.

AUTOSAR
AUTOSAR is a consortium of automotive manufacturers, suppliers, and tool developers that aims to develop an open, standardized automotive software architecture, and the AUTOSAR specification already includes the automotive TCP/UDP/IP protocol stack.

AVnu
The AVnu Alliance was formed by Broadcom in collaboration with Cisco, Harman and Intel to promote the IEEE 802.1 AVB standard and the Time Synchronization Network (TSN) standard, establish a certification system, and address important technical and performance issues such as precise timing, real-time synchronization, bandwidth reservation, and traffic shaping.
