It is reported that on March 31, the second generation of Haier Ali smart TVs will be launched, featuring super-large storage, ultra-clear visual effects, iterative dual-upgrade of full software and hardware paths, full-featured voice control, and dual channel audio output technologies.
It is worth mentioning that Haier Ali II TV provides users with a free eco-sphere worth 6,888 yuan, which includes not only 4K and Blu-ray movie zones, massive 4K preschool education resources, but also cloud k-song functions. At the scene, a singing enthusiast invites his friends to enter the virtual room to sing together, which is comparable to KTV's sound effects.
2. Changhong CHiQ second generation TV release

At the press conference, Changi released the CHiQ second-generation TV standard 4K, including 5 models: 55/65Q2R (4K, LED surface), 49/55/65Q2C (4K, LED plane). And on the 27th, Changhong official online shopping mall and major mainstream e-commerce platform, the country's supermarkets began to formally sell.
3, Wanda e-commerce platform "flying net" online
In August last year, Wang Jianlin announced that it had registered with Tencent and Baidu to establish an e-commerce company in Hong Kong, with an initial investment of 5 billion yuan. Wanda holds 70% of its shares, Tencent and Baidu each hold 15%, and plans to invest nearly 20 billion yuan in 5 years.
Recently, Wanda e-commerce platform "Feifan.com" has been on-line. Unlike other e-commerce platforms, Feifan.com does not rely on cities as sub-stations, but uses Wanda Plaza as its radiation core.
According to the agreement at that time, Wanda, Tencent and Baidu will cooperate in the areas of account system, membership system, payment and internet financial products, establishment of a common point alliance, big data integration, Wifi sharing, product integration, and flow introduction. At present, it is not yet possible to directly log in to SkyFly with Tencent or Baidu account. Basically, other services are involved.
4, WeChat will push the membership system, friends limit will exceed 5000
It is reported that WeChat is testing the membership system, will be divided into quarterly and annual membership. After the user becomes a member, the friend can go online and can break through 5,000. At the same time, the paying member will add a friend circle decoration function. At present, some Tencent game employees have already participated in the internal testing. How specific WeChat members will charge and what specific membership functions are still unclear.
What is Battery Holder?
Battery Holders are devices used to hold and secure batteries in electronic devices. They come in various shapes and sizes, depending on the type and size of the battery they are designed to hold. Battery holders are typically made from plastic or metal materials and feature spring-loaded contacts that connect to the battery terminals to provide power to the device. They are commonly used in electronic devices such as toys, remote controls, flashlights, and other portable devices that require batteries for power. Battery holders are essential components in electronic devices, as they ensure that the batteries are held securely in place and provide a reliable source of power for the device.
Choosing the right Battery Holder.
The kind of battery holder required depends on the below factors:
Size of the batteries being used (AAA, AA, C, D, etc.)
Number of cells being used
Compatibility of the cells being used with the battery holder
Contact and terminal style
Most battery holders are specifically manufactured for a particular type of batteries. However, many battery holders will be compatible with similar batteries with different chemistries. One point to note here is that if a battery holder houses batteries of different chemistries at the same time, the power being delivered will be in line with the weakest battery. Hence, using batteries with the same chemistry is advisable for optimum performance.
Types of Battery Holder Mounts.
The way the battery holder is attached to the cell-powered device is known as the battery holder mount. The different types of battery mounts are:
Panel Mount:
A panel mount battery holder is a separate compartment designed to hold cells. It can be inserted into a cavity in the device that needs power. It can be removed when the batteries need to be changed. They are inserted in the device cavity by screwing in or have Flange Panels.
Slide-In Mount:
In this type of mount, the cells are inserted and removed by sliding in or out. They are the most commonly used mounts and also economical. When a cell is slid in place, it is held by a cover or by the opposing force of two terminals. This type of mount is quite reliable, too.
Chassis Mount:
This type of mount is fixed inside the main body of the device to a surface plate. These mounts come in plastic as well as metal.
PCB Mount:
As the name suggests, the PCB Mount is for when the battery needs to be on a PCB. It has sharp pins around the perimeter which can be used to fix it on a PCB. Usually, they are used to hold coin cells. However, PCB mounts are also made for AAA or AA cells.
Strap & Lead:
They are not entire housing units, but make it possible to attach a battery to an electronic device or holder. It just has a wire and two press studs to hold a cell. Replacement of the cell becomes easy in this method.
Snap-In Mount:
It consists of tensioned metal clips to hold a cell securely in place. The battery is to be pushed into the housing until it snaps in place. This type of mount is best suited for systems prone to shocks and vibrations.
Wire Lead Mount:
This type of mount provides a good level of flexibility in terms of the places where it can be used. It has two wire leads at one end while the other end can be fixed to the device being powered.
Surface Mount:
This type of mount is usually used for coin cells. It lies flat inside the device or within a circuit. It is open-faced and has button terminal contacts.
Through-Hole Surface Mount:
This is best suited to hold batteries where space is a constraint. Instead of being inserted into a cavity in a device, it is fixed on the surface of the device through holes.
Battery holders are often not taken seriously enough when designing systems. However, a reliable battery holder is an important component that contributes to the reliability of the entire system.
