At first, they just wanted to make a beautiful speaker, so they designed this shape.

Then the product manager said that we should be smart, so they developed an APP, made an intelligent connection, and set up a voice recognition playback system.

The boss said that the Bluetooth connection was really unstable, and I couldn't cut off the songs played by the bedroom speaker when I was squatting in the toilet. So they made a WiFi connection, and everyone can do what they want without running out of the signal range.

Xiao Wang, who loves music, said that we are all so smart that we can listen to so few songs, which is a bad review. So they tried their best to link up with Xiami Music, owned a huge music library and took a prototype to find someone to invest.

Lao Zhou played this, which sounded fun, but not good. They gritted their teeth and flew to America, found the best speaker they could afford and redesigned the stereo. Sounds good, too.

Finally, things will go on the market, and we will have a meeting with the marketing department for pricing. "If this thing doesn't make money, it has to sell for one thousand." They said hopefully. "I bought a bedside speaker with a thousand dollars. Who else does this now? Just sell it for 499. It's Lao Zhou's money anyway. That's settled! " "......"

So the smart speaker, with crazy and cool functions and outstanding sound quality, sold for 499 yuan. (The above plots are all made up by my brain and only represent my personal views. If it coincides with the actual story, I can only say that I was right. )

Generally speaking, in my opinion, the Knock-Knock smart speaker is a practical bedside speaker with great value. In domestic smart speakers, the sound is generally good, listening to music is more troublesome, and the sound is not satisfactory. It is more reliable in this price range of several hundred dollars. (The other one is more reliable, but it is still worse in the convenience of connection. )

▲ Six touch shortcut song single keys, the play key and the song cutting key are huge and easy to press.

The first is the appearance. Since BOSE created this "male model" of "what should a small integrated speaker look like", the use of this design, which is very good in acoustic design, face value and convenience, has quietly become popular. As for the face value, you should have a basic judgment when you look at the picture. Official map fraud is objective, but as a smart speaker of 499, such workmanship can already be praised.

▲ The interface on the back retains the traditional AUX IN, and the USB port seems to be able to play U disk songs, but it is basically useless for the powerful music library.

In terms of volume, I personally suggest putting it on the bedside table, bookshelf or living room coffee table because it needs to be connected to the power supply to work.

▲ Official maps always look good.

About the specific functions of the Knock Knock smart speaker, you can see the details on their official website, such as voice function, APP control, six song list shortcuts and so on. I won't talk about it here. There will be explanatory text on the picture and the screenshot of my brother's own mobile phone. As a "music lover", I'd better talk about the sound performance of the speaker.

As far as the hardware configuration is concerned, Dongdong smart speaker adopts two three-inch aluminum high-power diaphragm units, with a cavity volume of 2.3L, with a TI dual-channel digital power amplifier with a power of up to 50W and an audio supplementary capacitor produced by CBB. This configuration can be said to be "luxurious", and Bose's most famous Soundlink series speakers are such hard configurations.

▲ The materials used are hard.

The translation of this passage just now is "the materials used in this thing are quite awesome, not worse than the foreign brands selling for more than 2,000 yuan."

In terms of sound performance, knock-knock smart speakers must first have strong enough sound pressure (loud enough sound) and relatively solid low-frequency response based on this volume. I think for a speaker who locates the ordinary family, being able to do these two things is enough to get a name of "good voice" in the market.

▲ The perfect HiFi sound quality is not, but the good value is true.

After doing this, the Knock-Knock smart speaker still has certain sound details and warm and thick listening feeling. Although there are still some dull sounds, which are not suitable for appreciating instrumental music and other minor problems, Knock-Knock smart speakers are certainly good for the public and beginners who have a certain pursuit of sound.

Specifically, the sound pressure level of the knock-knock smart speaker is enough to fill a large room of 30 to 50 square meters, and the general bedroom and living room are enough. His sense of hearing has been trained by Zeng Dejun, the "father of courage" in China. His voice is warm and mellow, and he has a very good sense of hearing in male performance, while his mellow female voice and most pop music performances are also good enough.

▲ There are so many things to cooperate with, which is still quite powerful.

In terms of music library, Dongdong APP cooperated with a large number of radio stations or music apps such as Shrimp and Douban FM, and combined with a large number of accessed radio stations, it created its own powerful "audio information database". This audio library is so powerful and convenient that it looks and actually sounds. If you want to listen to something, you can click it directly on your mobile phone and the speaker will start playing by itself.

A few screenshots in the APP, the interface is simple and generous, and the operation is quickly started, which is really good.

WiFi connection is higher than Bluetooth connection, I don't know where it is. As long as there is a WiFi environment, the Knock-Knock smart speaker can independently connect to the network to play songs. At the same time, the interaction with the APP is also very good. With the first connection, the phone can control the speaker freely.

▲ There are many radio stations that can be on demand, and broadcasts can also be listened to with 0 delay.

As for the speech recognition function-I think this thing is quite useless, so I have no experience. Shouting at a square "Give me an old Chinese doctor with flower porridge, which is the most popular one in douban" is still an embarrassing and second-rate thing in Chinese mainland, isn't it?

Summary: This 499 gadget has excellent workmanship, solid hardware configuration, convenient and intelligent smart APP and connection, and also has a strong audio information database, which can no longer be simply called a music library. In actual use, it is convenient and pleasant to listen to, and there is nothing unpleasant or obvious short board-as long as it is not the 360Logo on the back or you can't leave the power supply, you feel uncomfortable. In my opinion, this is a conscience work that is worth the money in domestic low-cost smart speakers. If the family lacks such an alarm clock in the morning, a radio for lunch and a bedside speaker for fitness BGM at night, it is always right to buy it.
