In recent years, with the gradual maturity of signal processing and electroacoustic technology, audio equipment has once again become one of the hot spots in intelligent electronics by taking advantage of the Internet. In addition to traditional audio devices such as HiFi earphones and Bluetooth speakers that add Internet factors, another emerging player in the spectrum field, the music box, has also begun to emerge and become more and more popular in the market. When it comes to music cloud boxes, some people may not know much about them, but when it comes to TV boxes, everyone is familiar with them. TV box can add new functions such as network TV to traditional TV, making traditional TV become intelligent TV instantly. Music cloud box has similar functions, which can wirelessly transmit music from intelligent devices to traditional audio, making traditional audio become wireless Bluetooth audio, eliminating the trouble of connecting, and greatly simplifying the use of audio. At present, there are many music boxes on the market, such as Baidu Wireless Music Box, Xiaoyang Music Box, etc., but these music boxes are either too simple in function or not beautiful in appearance. Today, what Xiaobian wants to bring you to experience is this music cloud box that combines function and beauty produced by the Internet giant Pinsheng. I'm very lucky to have the opportunity to try this product. Thank you for your trust!

1. Appearance

Still the familiar package or the excited mood, the exclusive symbolic express bag of Pinsheng has become one of the marks of Pinsheng.

Unpacking the packaging bag, we can see the protagonist who has won many international awards - Pinsheng Music Cloud Box. The mainstream plastic packaging of Pinsheng has the main parameter information of the product on the back, and the transparent plastic box can directly see the product

Although this kind of packaging design is simple and beautiful, Xiaobian needs to complain a little here. This kind of package is easy to open, and it is not easy to see whether it has been opened. Personally, it is better to stick a seal on the carton package.

The main product list includes 1 music cloud box, 1 power adapter and 1 user manual

This is a beautiful music box, which is derived from the appearance design of modern piano. The excellent paint surface feels particularly comfortable

Four anti slip foot pads on the back at four corners

The left side is equipped with standard 3.5mm audio interface and USB interface, which can not only play music on smart devices, but also play music in mobile storage devices such as USB flash drives

The wireless switch is set on the right

On the back of the cloud box, there are power input interfaces, optical fiber interfaces, network interfaces and lotus interfaces, which can be described as rich interfaces and complete functions, and will be described in detail later

S/PDIF optical fiber interface can be used to connect speaker equipment with optical fiber interface to improve transmission quality. For traditional audio, music transmission can also be completed through Lotus interface

2. Functions

In addition to the wireless music transmission function, the music cloud box is also an intelligent router with a high transmission rate of 300Mbps. It has wired connection, wireless relay and other functions.

The network cable interface of the music cloud box is a WAN/LAN two in one interface. When used as a primary route, it can only provide access to the Internet for wireless connected devices. There are two indicators in front of the music cloud box: power supply and WiFi. They are small and exquisite, eye-catching, but do not affect sleep. I like them very much

Connect the wireless signal of the music cloud box and enter 192.168.168.1 in the browser to enter the network setting interface

In the login password, the minor editor made an embarrassing "own dragon". He always thought it was 8 zeros like the wireless initial password, but found it was originally pisen. Like most routers, the main interface mainly includes network settings and router settings

Both the setup wizard and the Internet settings can set the network. The Internet access mode can be broadband dialing, wired connection and wireless relay

The password of the wireless name of the music cloud box can be set in the WiFi settings. Previously, the user name and password can be set in the login settings. Of course, the music cloud box also has the function of viewing linked devices, so that users can view the network usage at any time

In addition to the router function, the music cloud box has another function that Xiao Bian likes very much. That is, it has a Lighting interface, which can directly charge most Apple products, which is very convenient

With the 5V 2A charger that comes with the music cloud box, it can basically complete the charging of the iPhone 5S in more than 1.5 hours. However, I don't know why the interface feels dirty. Maybe it's because I didn't get a new product

3. Analysis

Speaking of this, the most important wireless transmission function of music cloud box seems to have not been mentioned yet. For traditional audio, this function is really very powerful. The bulky old audio with music cloud box will become a wireless Bluetooth audio instantly. However, music cloud box does not seem to play a significant role in speaker devices with Bluetooth function, which is not the case. The Pinsheng music cloud box is not only a music cloud box, but also a music box with HiFi level high-quality sound transmission. The built-in high-quality audio decoding chip can minimize the loss in the process of audio quality transmission. What is the effect of lossless audio quality? Xiao Bian made a simple horizontal comparison evaluation.

Test equipment includes Pinsheng music cloud box, Pinsheng portable Bluetooth wireless speaker, audio signal acquisition system and analysis software

In order to facilitate the operation, the music cloud box is powered directly by the mobile power supply. The whole test process is no problem. The Micro USB charging interface has advantages

The editor tested and analyzed the output audio of three different connection methods, namely, the mobile phone connects the audio directly through the 3.5mm audio interface, the mobile phone connects the audio through Bluetooth, and the mobile phone connects the audio through the music cloud box

Music cloud box means a row of hidden volume indicators, which can be adjusted through two touch volume keys, very convenient and practical

The time domain signal and spectrum analysis results collected by the three connection modes are as follows

As you can see, the music cloud box connection in the low-frequency part is smoother and more stable than the other two methods, which can effectively improve the transmission sound quality!

4. Summary

As an intelligent device integrating cloud routing, music box, charging socket and other functions, Pinsheng Music Cloud Box can effectively solve the problems of various devices at home and bring users an excellent experience. In addition, the exquisite appearance design of the piano makes it a beautiful work of art. It is beautiful everywhere in the home, which is one of the reasons why it won the prize in the current home competition. However, there are some small areas that need to be improved. For example, the application software Pisen Cloud of Pinsheng is still unable to be used on some models of the iPhone 5S.
