Write in front

Traditional speakers have gradually withdrawn from the market, and the era of wireless smart speakers has arrived. It is not the first time to contact with wireless smart speakers. I have used Xiaozhi super speakers and DingDong smart speakers. Xiaozhi speakers came into the market early. It should be the first smart speakers supporting voice control in China. It is small, portable, convenient and practical. Due to the size and number of sound units, the sound quality needs to be improved. Compared with Xiaozhi, DingDong Audio has greatly improved its speech recognition rate and sound quality. It is not portable and has no built-in power supply. Unplug the power supply and it will never sound. The author recently came into contact with the latest smart audio product - O2 Cloud Audio. The cobblestone shape is impressive. It not only supports voice control and gesture control, but also adds a round touch screen, which makes the speaker completely free from the shackles of mobile apps. It can be said to be a versatile smart speaker. Next, please join me in the experience.

Unpacking appearance

▼ O2 Cloud Audio is packaged in a common paper box, which is much larger and heavier than expected. The front is printed with the product's appearance.

When the speaker is placed on the desktop, it will have a tilt angle. Good structural design ensures stability.

▼ The circular rubber base at the bottom also ensures stability.

▼ The power button, power interface and inversion hole at the bottom.

Control experience

▼ As a wireless smart audio, of course, it can only be used normally if it is connected to the wireless network. O2 Cloud Audio, with its own display screen, can easily search the network through the touch screen, enter the password, and access the network.

▼ The audio system is designed without buttons. In addition to the round touch screen, the corresponding functions can be achieved by touching the four areas of the screen with the palm. Above: Play / Suspension; Left: lower the volume; Right: increase the volume; Below: Turn on voice control. It can be touched gently, and the response is very sensitive, but the chance of accidental touch is also high. Sometimes if you want to move the speaker down, it is easy to trigger one of the functions.

▼ Round LCD The touch screen is sensitive to touch and clear enough. You can switch to different interfaces by sliding left and right, and switch songs by sliding up and down.

▼ This is the scene selection interface. There are a variety of scene music to choose from, and they are often updated. Different styles of music are suitable for different application scenarios. You can listen to some soothing music before going to bed, and it is more suitable to listen to some fast rhythm songs when you exercise. This is also O2 A special function of Cloud Audio.

▼ This is the music playing interface, which adopts the style of old records and has a nostalgic taste. The yellow progress bar in the outer circle can also display the progress of the song playing.

▼ In the setting, we can select spectrum or weather as the standby interface, which highlights the role of the display screen.

▼ In addition, O2 Cloud Audio also supports gesture cut song and voice control, two relatively new functions, but the actual experience is not good. Switch songs by sliding your palm from left to right or from right to left on the top of the screen. You need to be close, about five Cm, and often no response, not too sensitive. Say "small" according to the instructions O Hello, please play …” , basically does not work, and can only trigger the voice song search function by touching the hidden button at the bottom of the screen.

▼ The advantage of smart speakers is that they can improve various functions by upgrading firmware. When I use O2 In the past few weeks, Cloud Audio basically has firmware upgrades every week, and the product's control experience is gradually improving. It can be seen that the manufacturer's efforts have never stopped.

App use

Actually, for O2 For cloud audio, mobile phone app The role of, app Basically, all the functions that can be realized can be realized through the touch screen of the speaker. app The biggest function is to realize the function of mobile phone to control the remote speaker, which adds another interaction mode.

Sound quality performance

The above is an introduction on the official website. After actual experience, I found that this is true, O2 The sound quality of Cloud Audio is quite satisfactory. And Xiaozhi Super Speaker and DingDong Compared with audio, O2 Cloud Audio is obviously better at sound quality. O2 Cloud audio adopts typical“ two point one Channel "Design." two point one In two "Means standard dual channel (stereo);" two point one In one "Refers to the general frequency division output 100Hz The following "bass" channel two point one "Channel" is a basic condition for stereo and bass effects.
