A speaker plays Lenovo to enter the intelligent hardware horn

The public test can be considered large-scale, Zhang Aunt 400 public test qualifications, Lenovo Forum also has 1,000. What is different from the past is that the focus of this activity is not on the promotion of products, but on the feedback of product problems and suggestions for improvement. Lenovo's smart speaker looks more like a smart hardware entrance. "Hello Lenovo, turn on the TV," "Hello Lenovo, turn on the air conditioner," "Hello Lenovo, turn off the lights," but currently Lenovo's lack of intelligent hardware, this speaker is only a smart speaker for the time being.

From the speaker alone, this speaker is very large and has no battery, so don't want to carry it. The audio source can be Bluetooth. At this time, Bluetooth speakers can play the mobile content. You can also use wifi to play network content. Control, in addition to switching and volume adjustment, can be achieved through "Hello Lenovo...".

The rectangular box is used for the packaging and the lids open. The volume is very large, and the weight of two catties is considered heavy for speakers of this category.

Open the lid and the cylindrical appearance of the speaker appears before your eyes. Above the middle is the only physical button for the entire speaker, responsible for switching operations. A circular hole on the edge, in order to distribute 8 top microphones.

Exposing the first half, live off the shape of a mug. The top trapezoidal chrome plating gives the metal texture, and the bottom white ABS has no plastic feeling and the surface has the texture of the paint.

Accessories are installed in the upper cover. This package is worthwhile. Can not get out, must tear the accessories paper to get it out. . .

Remove the speaker, the overall cylindrical shape, the lower half of the linen. In the second half of the theme speaker, the speaker is wrapped in linen, which is beautiful and does not affect the sound source. The difference in different colors is also the difference in this linen.

The connection between the two materials in the upper and lower parts is neat and smooth.

The upper chrome reflective effect is very good, you can see the white bars in the speaker through reflection. Inside is the light source. This not only reflects the light but also the volume adjustment knob.

Light effects.

The base is a silicone material that cushions the vibration of the speaker and increases friction. However, it is easy to get dirty.

The power supply is at the bottom and the power plug is not a Mirco USB but a round excuse. The bottom groove avoids the power cord so that the power cord does not affect the placement of the speaker.

The power adapter is a bit large, but the work is still good, highlighting the style of the factory. 20V1.5A, so high power, so did not use Mirco USB interface.

Speaker connection can also be convenient, download smart Lenovo app, and pairing settings in a wifi environment. Voice prompts also have four sound options. One of the beauty voices is the voice of Lin Chi-ling.

Wait for the configuration to enter the smart speaker's main interface.

The app's main interface is the full functionality of the speaker. Music comes from Cool Music and Himalayan. You can set an alarm to remind you. Speakers can voice messages, memos. You can reserve a taxi and tell the weather through the speakers. All this function is through a password "Hello Lenovo."

This is Lenovo's first generation product, and there are many features that need to be improved:

First, as a web player, the quality of content needs to be improved. "Hello association, play XXX singer song" song layout is not satisfactory. "Hello, Lenovo, play a certain song" is mostly a TV program, a music source for a concert, not a song in a regular album.

Secondly, the voice control is convenient, the shutdown needs to be manual, the volume needs to be manual, and the English song cannot be identified to bring great inconvenience. The app can't control the voice. You want to control the speakers to go to the speakers.

Finally, as the only display of the speaker state, the lighting logic is not perfect. The operating status light is dark and I do not know if this speaker is on or off. When you tap the power button to pause, voice cannot wake up the speakers, you have to pull the power to restart.

Lenovo smart speakers are the beginning of Lenovo's entry into smart hardware and also the future of smart home intersections. It's just a beginning. It may not be perfect. But with the hard work of Lenovo, he will grow slowly. In the end, you will not be able to separate from it.
