When it comes to passive speakers, I also refused at first. Vitas feels that the location of passive wireless speakers is a bit awkward. People who don't listen to music very much may not want to buy speakers; Enthusiasts can't appreciate the sound quality of passive speakers. A friend who used to work together as an electroacoustic band, a music enthusiast, said: "Talking about the sound quality with the wireless speakers is playing rascals." But after all, the enthusiasts are a minority. For ordinary people like us, the passive wireless speakers are nothing more than to find some fun for life. Its use scenarios are divided into indoor and outdoor.

Indoor: Party to enliven the atmosphere, work and leisure background music, watch movies to improve the sound effect and volume... When traveling, take passive portable speakers, which will save the boring time of traveling and staying in hotels.

Outdoor: cycling, walking, picnicking, and yes, square dancing can create an atmosphere.

For a mobile phone or laptop, or even today's portable projector, the sound quality and volume of the wireless speakers are still higher. Especially for today's smart phones, where the power is more precious, there must not be many people willing to use their mobile phones outdoors for a long time. For traditional speakers, wireless speakers are more portable, and sound sources are more extensive and flexible. The wireless speaker is not a pure device. When listening to music with it, it is often interrupted by various messages and push sounds. It is not an enthusiast, but for ordinary listeners, it is a small item to improve the quality of life.

Today's protagonist has Personalized and customizable mesh cover, 5200mAh large capacity power pack, portable, Support WiFi, Bluetooth, audio cable and other connection playing methods, software app Rich music library resources, DRA music format and DPS gain technology has obvious advantages. Now, let's talk to Let's have a look at this one, Vitas Electric Python 2 Face Smart Cloud Audio See how it will bring us.

Appearance and details

The package of CrazyBoa, a smart cloud audio system of Python 2 Face, is simple. Does the designer pay more attention to the appearance and sound quality?

As a stereo, Vitas also focuses on workmanship and sound quality, so the packaging does not show too much.

The trial equipment is provided by "Understanding Mobile Internet&Future" [Lei Feng].

The package box contains: cloud speaker host, power adapter, audio cable, warranty card, instructions for use, music starts from here!    

Dian Mang, founded by @ Guangzhou Tianyun Yunyin Industrial Co., Ltd., is a new power of Internet audio in China. Guangsheng Assets, one of the three provincial state-owned asset management companies in Guangdong, the only developer of the national standard "DRA" for digital sound effect processing technology in China, Guoguang Appliance, the first comprehensive ranking in China's electroacoustic industry, China Electronics Top 50 Tongfang Shares, China's top ten best advertising company Himalayan Advertising, and China's largest Internet legitimate music operator Jiutian Music.

The All in One cloud sound ecosystem closed loop built by Dian Mang will change the user's habit of enjoying music and make the sound completely synchronized with the lifestyle of the Internet era. Dian Mang Technology has developed the world's first C-Play cloud music operating system, and is committed to building the Internet intelligent cloud sound ecosystem of Allinone.

The fluorescent green strap matched with the electric python 2 face and the pattern is very soft, which can be easily disassembled and assembled through the buckles on both sides (like the guitar strap). The strap is very comfortable to hold in your hand.

The measured thickness of the electric python 2 face is 70.9mm. The charger is slightly larger, which is equivalent to more than half the volume of a standard third-order magic cube.  

On May 20, 2015, Anaconda released the new Anaconda 2 Face and Anaconda 2 Pro in Dali, Yunnan Province. The Anaconda 2 Face has smooth brushed metal on the side, and thick wool fiber woven cloth is wrapped on the front and back. The standard version has four basic patterns: cat's eye green, watermelon red, hill silver, and facial makeup red. If you can't meet the aesthetic requirements, you can also customize exclusive patterns. Soft as a thunder snake wrist strap, the handheld strap turns the electric python 2 Face intelligent cloud audio into a handicraft. Vitas got the standard cat's eye green.

Is this a bag? Audio? portable battery?

yes! It's all. But this bag can't hold anything.

The lady goes out with it. With its eye-catching appearance, many people will ask: Girl, what kind of bag is this?

You can proudly tell him that this is a cloud stereo. Cloud? Dizzy!

The electric python at home is more like a handicraft.

The Python 2 Face supports the patented lossless music format. DRA is the abbreviation of Digital Rise Audio. Developed by Guangzhou Guangsheng Digital Rise Technology A digital audio coding technology is currently the national standard for audio coding. DRA audio standard supports both stereo and multi-channel surround sound digital audio coding and decoding. Its biggest feature is that it uses very low decoding complexity The compression efficiency of the international advanced level has been achieved. Since all signal channels in the encoding and decoding process of DRA technology have 24 bit precision capacity When the rate is sufficient, it can provide sound quality beyond the hearing ability of the human ear.

The interface area of the electric python 2 face is at the lower left of the back, providing the necessary AC power input, 3.5mm headphone output, 3.5mm AUX input, USB charging interface, there is also a hidden TF card slot that has not been put into use (it can be seen when disassembling the machine at the back), and the power indicator can also be seen beside it. What's not enough is that the power of the electric python 2 face is low, except for the small indicator light on the back, which is not easy to find, there is no sound to prompt the low power. It will be silent when listening to it. I hope @ Guangzhou Tianyun Yunyin Industrial Co., Ltd. can improve the firmware and do 30% power reminding charging.

Five round buttons are arranged on the top of the electric python face side by side, which are power/mode switch, My favorite music, play/pause, volume decrease and volume increase.

The leftmost indicator light can display white (Wifi mode), green (Line in mode), blue (Bluetooth mode) and purple (USB mode) lights according to the different modes switched. Click the power key to switch modes (this function can also be switched in the mobile phone App), and long press the power key to switch on and off.

The top five keys have a short key path, slightly higher than the metal panel. The middle part is concave to meet the finger curve. The press feedback is clear, and there is a drip sound feedback (the horn of the key circuit board sounds, which can be clearly seen after the disassembly of the article). The gap between the key mold (non-metal) and the panel is even, and the overall appearance is fashionable and the workmanship is fine.

Acoustic performance

Whether it's a Wifi cloud speaker, a Bluetooth speaker, or a speaker, the sound quality is the ultimate factor to measure them. The performance of high, middle and low frequency is directly related to our Sense of hearing.

This time, Vitas will experience the sound quality performance of the electric python 2 face through several pieces of high, middle and low frequency music.

When we take apart the electric python 2 face, we can see: 2 full frequency speakers (on both sides of the front), 1 low-frequency speaker (between the two speakers), 1 passive radiator (on the back), The electric python official claimed that "the exclusive ultra-thin patented technology of the low-frequency loudspeaker enables the loudspeaker to have a full stroke while being flat and thin. It has a long stroke that the same loudspeaker cannot match, and it can produce a richer bass effect. The sound resolution is increased by 43%."

The "passive radiator" of the electric python is actually a bass unit passively moved by the front active bass speaker. The passive unit and the active speaker unit are slightly different in appearance. The "passive radiator" (passive unit) has no voice coil and drive magnet, just a paper basin, and is not connected to any voice coil or circuit. Passive radiator is usually used to adjust the bass, so that the designer can adjust the overall voice color of the speaker. The passive radiator makes a passive sound driven by the air in the loudspeaker box by the active unit in the loudspeaker box. The passive radiator is usually used to replace the inverter tube to adjust the sound quality of the smaller box and make it have better bass performance.

After disassembly, it was found that the sound generating module of the electric python 2 face was fixed with bolts and black glue. As can be seen from the disassembly below, even the outgoing key array cable was sealed with glue, which ensured that enough air was pushed to provide a strong bass when the electric python made sound inside.

Anasazi Stardance, the low-frequency test song of Ana constrictor 2 Face, is the opening song of the album Killer Drum and the legendary test song of enthusiasts. At the beginning of the music, the low frequency, low and powerful, rolled in, like the rumbling sound of thunder on a recent thunderstorm in Beijing. bass Some parts are thick, powerful and elastic, without losing too much detail on the low frequency. For the thickness of the sound generating module less than 6cm (remove the panel), the electric python passive portable wireless speaker bass Part of the performance has far exceeded my expectations. Especially after the DSP sound effect enhancement function is turned on, the continuous bass momentum pushes a large amount of air to the listener's ears through the 29.8mm * 19.6mm sound generating surface. The bass is very deep, and is not forced to render the "electronic" very fake bass like many audio systems. The volume is adjusted moderately. Holding the electric python in your hand, the powerful bass vibration feels that the sound of nearly 2kg beats between your hands. The electric python 2 face has good bass performance, which is also related to the large caliber passive radiator on the back. It pushes a lot of air backward, which is very comfortable to listen to.

The middle frequency test song "Rolling Red Dust" of "Electric Python 2 Face" - singer Zhao Peng. Zhao Peng is a bass singer. His voice is within the range of sound box, It belongs to intermediate frequency.

The male voice part of the songs I heard was thick and appealing, with strong penetration and good performance.

High frequency test of Electric Python 2 Face "Audio Demonstration of Triangle". When you hear the striking triangle iron, you can send out a clear metal knocking sound. The overtones after striking belong to high frequency and ultra-high frequency, clear and transparent.

One Cool Remove, the high-frequency test of the electric python 2 Face, The first tone of the music can be heard with exquisite, long and analytical "cymbal" sound, and the ending sound is rich Rich, reflecting a more detailed and transparent high-frequency, very good. But the high-frequency performance is a little dull, like the speaker is covered with a layer of gauze. Yes, the electric python 2 face is covered with a layer of cloth at the front and back (front and back wool fiber can be customized cover), Vitas thinks that the high frequency performance speaker like the electric python 2 face is more suitable for playing background music in offices and other places. The volume is set at about 30% so as not to affect the speech. There is no sense of dominating. It is very soft Soft is very comfortable. The household is placed in the bedroom and living room to create a warm and elegant atmosphere.

According to the test, the performance of the electric python 2 face in high, middle and low frequencies is very good, meticulous and appealing, and the stereo sound field is rendered in place, especially in low frequencies The soft, magnetic and cohesive voice exceeded my expectations. For a portable passive speaker, it not only has an eye-catching unique appearance, but also uses the flat shape The cuboid shape gives the speaker more space to push head-on, and has more plane volume for realizing low frequency, Strong sense of hearing and hierarchy.

The excellent sound quality performance of Dian Mang 2 Face is inseparable from its advantages of using DC 12V working power supply to improve power, increasing bass radiation in a closed working space, improving air propulsion with a 12 inch large sound generating surface, winning the 2012 CES Innovation Award from the United States, excellent design ideas and manufacturing processes.

In a 30 square meter room, the electric python 2 face can sprinkle energy all over the room, and the quality and quantity are no less than some household active 2.1 speakers. The outdoor barbecue and party can also give a satisfactory answer, and the passers-by don't know that the high-quality and powerful sound is from this handicraft like a lady's satchel. In the category of thousand yuan portable audio, the sound quality performance of Dian Mang 2 Face is very worthy of the audience.

Complaining: The electric python 2 face has obvious bottom noise and current sound. After starting up (it takes about 8 seconds), you can hear the bottom noise within 0.5 meters in the quiet room, and you can hardly hear it 1.5 meters away. This will not affect the normal playing experience of the sound.

The measured charging voltage of Battery 2 Face is DC 12V, and the full charging voltage of USB power supply is 5.17V, which can be used as a 5800mA power bank when it is turned on. However, when the charging current is 0.8A, the voltage drop is large, from 5.17V to 4.79V.

According to the official statement of Electric Mang 2 Face, it has played for 8 hours. In fact, Wifi connection is used. The DSP sound effect is always on, and the indoor volume is about 40%. Occasionally, the volume is turned up when the songs are popular. After about 6 hours of comprehensive use, it automatically turns off when there is no electricity. Fully charged for about 4 hours, for reference only.

􀁺 Mobile phone app and dismantling

After disassembly, it was found that the sound generating module of the electric python 2 face was fixed with bolts and black glue, and even the outgoing key array cable was sealed with glue, which ensured that the passive radiator could push enough air to provide a strong bass when the electric python was making sound inside.

The metal shell is thick and well sewn.

Disassembled keys and circuit boards; Hidden as input TF card reading slot; The extended key cable is also bonded with black glue with high viscosity; The small horn for key feedback drip tone is installed on the back of the key circuit board, and there is also a data interface that is not connected to the cable.

The above figure is the welcome advertising interface; Audio selection interface; Main mode interface.

The CrazyBoa software on the mobile phone side of Python 2 Face needs to be improved in the following two aspects:

Vitas uses Android Meizu MX5, version 5.0.1, and CrazyBoa software can't control the sound volume normally by using the volume key on the phone side. After pressing the volume key on the phone side, the sound volume will automatically decrease to the minimum. You must touch the volume key on the App interface and then touch it up and down to increase or decrease the volume. Try to use the IOS system device side key to increase or decrease the volume.

Another disadvantage is that the font on the help page of the mobile app is too large, and can't be changed by touch. The appearance is very poor. It's a small problem. I hope it can be improved.

When connecting to a unified Wifi network with a mobile phone for the first time, you need to press the volume -+keys at the same time to identify.

While providing local file playback, it also has a wealth of online resources, many of which use the exclusive DRA format, which is better than MP3 audio quality.

For example, if you select children's music in the category, there will be many categories. If you subdivide songs in the category, you will be amazed by various high-quality resources. What's more, high-quality audio is recommended.

Recommendations for various categories In addition to the common classification based on singers and styles, the electric python has also divided special channels for music in the format of cooker and DRA, further refining the music classification to meet the needs of different groups. Through searching several songs, you can find multiple versions. If you often want to listen to music, but don't know what songs to listen to, the songs in your mobile phone may have been listened to for many years. The classification in the Python software can definitely satisfy your appetite.

The electric python 2 face looks amazing and personalized, and supports customization. DRA patented lossless format and DSP sound enhancement technology have delivered a satisfactory sound quality answer in the 1000 yuan smart cloud sound camp. Powerful software resource classification is very rich. Although there are some minor defects, the overall cost performance is very high. It is also hoped that Guangzhou Tianyun Yunyin Industrial Co., Ltd. can design and manufacture more and better electric python series audio and video equipment for public use.  

If you suddenly want to listen to style music, but do not want to search and download high-quality music one by one, Anaconda 2 Face Smart Cloud Audio can help you do so.
