As we all know, appearance is the first impression of a product, so it plays a key role in the user's decision whether to further contact. In fact, the appearance and interaction design of each product involves various complex factors.
At present, the appearance colors of smart speakers are all black, white and gray, which has high market acceptance and better reflects the sense of science and technology. Secondly, because young people are interested in the prices of these new products, the simple Nordic style is very popular among young people. At this time, the design of the speaker should be concise and not too abrupt. Moreover, the design is often not isolated, and there will definitely be a light array and various function buttons on the appearance. When designing the appearance, the designer must also consider whether the effects of these function keys and light array are unified as a whole.
Xiaomi Voice smart speaker adopts modern minimalist body design, round transparent body, black is more calm and deep, and silver is mysterious and smart. It can be said that less fancy color matching can make them more concise and generous.
The buttons of Xiaomi Sound smart speaker are integrated into the overall shape. From the point of view of operation mode, the operation mode of smart speakers is not only rich operation forms such as clicking and pressing. From the functional point of view, smart speakers still retain the basic functions of traditional speakers, such as volume increase and decrease, power on and off, etc., which may conform to the user's operating habits, but the unique function of UWB music relay is more obvious.
Xiaomi Sound smart speaker contains many speaker-level technologies, including its 2.25-inch NdFeB dual magnetic circuit full-frequency unit and dual suspended passive transmitter. Next, let's look at the acoustic architecture of these drivers and passive transmitters.
2.25 inch NdFeB dual magnetic circuit full frequency unit;
The speaker of Xiaomi stereo is located above the sound box, and it is a 2.25-inch NdFeB dual-magnetic circuit full-frequency unit with power 12W, which can meet the required performance as much as possible under different listening heights and maximum stereo width. In addition, this all-frequency unit is matched with neodymium magnet (also called "neodymium magnet"), which is helpful to reduce unnecessary distortion and expand frequency response.
In small earplugs or small-sized speakers, many neodymium magnets are used, and large-sized ones are rarely used. Xiaomi audio with neodymium magnet also really surprised the author. Of course, neodymium magnets are used for large-caliber units, embedded speakers and ultra-low frequency speakers are also used.
Double suspension passive transmitter;
In addition to the full-frequency unit, Xiaomi Audio also has a flat diaphragm. Xiaomi calls it a double suspended passive radiator. Simply put, it is a symmetrical passive radiator. These two passive radiators are placed under the speaker, which is equivalent to using a bass port tube, also known as the exhaust system. For a small speaker, the ventilation system needs a long and narrow pipe to obtain a sufficiently low vibration frequency. This will occupy a large part of the limited volume in the speaker, and the air coming in and out from both ends of the thin tube will also make a lot of noise. The passive radiator does not occupy the internal space of the sound box and will not produce noise.
As far as a single unit is concerned, the Xiaomi Sound smart speaker is also moving in the same direction. After the vibration is moved to Xiaomi Audio, it will often cause the speaker to vibrate and affect the bass performance. However, after adding the symmetrical passive radiator design, the main power can balance the bass distance, and the performance of low frequency will be strengthened. Coupled with the calculation of audio blessing, real-time dynamic tuning can optimize songs. As a new attempt of Xiaomi on the speaker, Xiaomi Sound smart speaker is equipped with two-way tuning, which is the entry-level speaker of Hifi. But it has built-in Xiao Ai students' all-around assistant, mastering 1600+ life skills, persistent dialogue and more concise instructions. At the same time, it supports the linkage between voice control equipment and Bluetooth Mesh gateway, which can control more than 3565438+ billion kinds of intelligent equipment.
Generally speaking, Xiaomi Audio has more ways to play in Xiaomi's ecology, which is more advantageous than other similar products. You can also buy two sets to build a stereo, the price is 499 yuan, and you can still start.
