[Future trend of speakers]

With the growing development of wireless technology, the application of wireless transmission technology is increasingly accepted by all walks of life. If speakers used to be a must for desktop computers, now the definition is becoming more and more vague. Throughout the speaker market in recent years, due to the decline of desktop computer market, on the one hand, speakers are increasingly separated from desktop computers; The other side is also gradually moving towards laptops, mobile phones and tablets. The current wireless speakers can be roughly divided into three categories: 2.4G wireless speakers, Bluetooth wireless speakers and Wi Fi wireless speakers. 2.4G wireless speakers are out of date. At present, wireless Bluetooth speakers and Wi Fi speakers have occupied the mainstream. Wi Fi's privacy and anti-interference ability are not as good as Bluetooth's. Now, I will introduce you a Bluetooth integrated speaker to let you experience the charm of Bluetooth speakers!!!

[Trace back to the origin]

Source of Longines

"RoyQueen" originates from "King and Queen", symbolizing the ultimate dignity and extraordinary elegance of the royal family!
The Chinese transliteration of "RoyQueen" is "Longqin". The original intention of Longqin speakers is to present the original music, demonstrate the dignity of users with the best materials and the highest level of technology, and convey an extraordinary elegant temperament with the most beautiful design.

"RoyQueen" brand concept
Brand positioning: "Deliver noble fashion art with elegant design"
Product positioning: "distinguished design, high-quality material selection, extreme technology, superior sound quality"
Carlyle, a British writer, once said that "music is an angel's speech". Although music is invisible and intangible, it is everywhere and permeates every corner of the world. Among all arts, nothing can directly express people's inner feelings more than music, and nothing can open people's hearts more than music in human life. When we are happy, music with its beautiful melody draws people into exciting emotions; When you are sad, music gives people a kind comfort with its sad and lingering sound; In solitude, only music can accompany people through the long night most sincerely. "RoyQueen" believes that "music and emotion are connected", and only Longqin can accompany you "as a bosom friend"!  
The voice, the product soul of "RoyQueen", uses the ingenious creativity and technology of the top clocks in acoustics and dynamics to add the design soul to it. Turbo Bass dynamic bass technology is injected into the limited space and expressed in different tones.
Just like cheaper watches, they may sound a little muddy and disorderly, while millions of top watches must have ringtones that are well arranged, clear and exciting.

[Unpacking evaluation]

The editor thinks that the uniform unpacking evaluation is not interesting. He has made a dynamic chart for everyone to present. Now, the editor summarizes Longines. Longines continues its simple packaging style, with one Royqueen M600, one USB cable, one AUX cable, one quality assurance card and one manual. Simple and clear, the overall packaging is simple but also very careful. The speaker is wrapped with soft foam to prevent bumping.

Basic Evaluation

First, a family portrait, including a Royqueen M600, a USB cable, an AUX cable, a warranty card and a manual.

Longqin M600 gives the small editor a very strong feeling at first sight. The size of Longqin M600 is 250mm * 140mm * 60mm, which is larger than the speaker of the same configuration. The speaker weighs up to 1.4KG, so it can be estimated that the material used is relatively hard; It is mainly black, low-key and simple. The surface is made of fiber textile material, which has certain splash proof function.

The back shows the model, power input and company name of the speaker.

The bottom of the Royqueen M600 is designed to be made of black silica gel, forming a symmetrical design with the top part. The role of black silica gel is mainly attributed to two aspects: shock absorption and anti-skid.

There is a rubber plug on the upper back of the Royqueen M600. After opening it, you can see the TF card socket, power switch key, AUX socket, Mirco USB interface, and USB power output port. There are three playback modes for the Royqueen M600: 1 Bluetooth mode, 2 Micro SD card reading, 3 external audio source input. At the same time, it also supports multi folder switching of Micro SD card, and the USB charging port is also used as the communication interface of the card reader. The Royqueen M600 can complete the music copy operation in the Micro SD card while charging, so it is no longer necessary to plug or unplug the memory card. One interface can complete two operations at the same time. It is designed reasonably and carefully.

The battery is equipped with 8800mAh lithium battery, which can charge digital devices such as mobile phones when the speaker is turned off. The rated output voltage is 5V, and the maximum output current is 2A.

The editor introduces the functions and uses of the keys one by one. The first key (from left to right) is the Pause and Play key, which need not be explained in detail. The second key is to switch to the previous song, but long press is to increase the volume. Similarly, the third key is to switch to the next song, and long press is to reduce the volume. The fourth is folder switching. You can switch between different folders freely. You can create multiple folders in the Micro SD card to organize songs according to different music styles. When playing, you can use the folder switch key to switch between folders of different music styles. The editor thinks that this key is very considerate. The fifth key is the mobile power wake-up key, which simply means that the electronic device can be charged without power on by pressing once when charging, and the power can be monitored in real time. The sixth key is very practical. It is the Bluetooth answer key. When playing music with Bluetooth, the phone is often left in the bag or away from you. When there is a phone connection, you don't need to go to the phone in a panic to answer it, just press the Bluetooth phone answer button. The last m key is the switch mode key. You can only switch between Bluetooth, card reading and audio modes.

The Royqueen M600 is equipped with a bracelet with the logo of the Longines. The bracelet is made of leather and has a soft feel. There are rivets in the middle of the bracelet, which improves the grade.

(The picture is quoted from the official)

Two hollow parts can be clearly seen on the back of the Royqueen M600. These two parts are passive bass units with a size of 90X60mm. Using an official picture, we can clearly understand the sound unit structure of the Royqueen M600. The front of the Royqueen M600 is a 3-inch bass speaker and two 2-inch full frequency speakers, and the back is two 90X60mm bass passive units. The 5-series chip of Texas Instruments can guarantee the 17W rated power output of Longines M600 speakers.

[Audio test]

The Royqueen M600 has a wide sound range and strong bass in the actual playing effect. In terms of sound quality and timbre, the sound field is loose, natural, open and delicate, and the tri frequency performance is relatively balanced, especially the bass performance is significantly better than the previous generation of products. The editor listened to Mr. Hishiro's piano music Summer, One Summers Day, Black Eyed Peas Boom Pop, etc. The Royqueen M600 is magnificent, full and shocking. The performance of three frequencies in these songs: the low-frequency diving is powerful, the sense of quantity is strong, and it is not sloppy, especially the drum treatment is very simple; The mid frequency is prominent, round, natural, sweet and full of texture. When listening to pop music, the handling of voice is very mellow and expressive; The high-frequency part is real, clear, bright and free of burrs. For the performance of multi instrumental music, the sound positioning is not confused, and the overall sense of hierarchy and stereoscopy are relatively clear. On the whole, the sound of the Royqueen M600 is elegant and calm, with rich analytical power and layers. There is no obvious trend in timbre, and the sound background is clean. Its technology level and sound quality level are up to the top level.

[Conclusion]

The Royqueen (Longines) M600 is a versatile speaker suitable for different home environments. Its battery life and charging are very good. It is easy to use and easy to operate. In terms of design, I think it is perfect. It is not easy to design such excellent speakers with good sound quality at this price.

In terms of sound quality, I don't need to tell you more about watching the video of my audio test!

The Bluetooth 4.0 connection has no problem with transmission within 10 meters, which is enough to cope with the home use environment. Although wireless transmission is used, there is no obvious attenuation and delay of the sound. Of course, the built-in AUV audio cable connection can also be used to transmit through the wired mode (but the AUV cable is not long enough, a little insufficient).

Advantages:

In the in-depth reading and in-depth testing, the editor has summarized the advantages of the Royqueen M600. Here, we will not repeat them one by one, but just make a brief summary.

1. Sound quality is perfect.

2. High cost performance.

3. Strong operability.

Disadvantages:

1. Not easy to store.   

2. Engineering plastics are easy to get dirty and scratch.

4. The size is a little large and inconvenient to carry (for girls).

5. The AUV audio cable is not long enough.

6. The keys are not easy to recognize in a dark environment.

7. No radio function.

[Suggestion]

1. There is no matching App software.

2. The mold is not exquisite enough, and there is a feeling of scratching at some joints.

3. The machine body is short of memory. It would be better if WiFi was connected to the Internet.

4. If there is a voice function, it will be great.

5. The keys are not easy to identify in dim environment, so a backlight can be installed

6. Hopes to add radio function to facilitate the elderly to go out.
