1、 Preface:

Wolfgang Amadeus Mozart (January 27, 1756 - December 5, 1791), born in Salzburg during the Holy Roman Empire, is a European classical music composer. He is good at combining the beautiful things in art with the profundity that permeates life, and then combining the strong power, straightforward temperament, resolute will and the sense of practical significance. His works have their own characteristics besides the preciseness and symmetry of classical music. In his art songs, what is commendable is the perfect combination of poetry and music, which runs through his creation period, and therefore also reflects the artistic characteristics and creation characteristics of different periods. The theme of his music works is complete and has a distinct outline. There are also delicate and motivational links between small structural units.

January 27, 2006 is the 250th anniversary of the birth of Mozart, the Austrian musical genius. In this year of special significance, the art palaces of European countries are eager to awaken Mozart's soul of music. Therefore, 2006 is also called the first year of "Mozart Year". At the Vienna New Year's Concert on the New Year's Day, conductor Maris Janssens played the overture of Mozart's "The Wedding of Figaro" and Joseph Lanner's "Mozart Style Waltz". This signal was quickly accepted in China. Since then, looking for memorial themes every year has become the main direction of the classical music industry.

2017 is the 261st anniversary of Mozart's birth. On this anniversary, Shanjin Company produced a mini Bluetooth radio named after Mozart: Shanjin MOZART. Hereinafter referred to as: 【MOZART】

TIPS： It's very interesting to play Mozart's music with MOZART, ha ha.

2、 Unpacking:

This MOZART transport case is customized by Yamajin. The side of the transport case is printed with the eye-catching LOGO of Shanjin Company.

At the bottom, there is a mark that conforms to the national standard for packaging and recycling.

The product packaging box of MOZART uses black as the main tone, and the front side is matched with the hot gold Mozart head silhouette and signature, showing a distinctive high-end atmosphere. In order to ensure that the products received by users are brand new, the packaging box is specially plastic sealed.

On the side of the package are also the words of [Mozart, the music prodigy] and [SANGEAN] in hot gold. It complements the head portrait and signature on the front.

Open the packaging box, and MOZART's family photo includes: MOZART Bluetooth speaker * 1, 3.5mm external soft antenna * 1, Micro USB power adapter * 1, portable packaging bag, and product instructions.

Note: I think there is a lack of AUX IN wire here. Otherwise, it will be more perfect.

External soft antenna is one of the selling points of this MOZART. When the location signal is poor, you can install a soft antenna enhancement model on the device. When the position signal is good, there is no need to use an external antenna. This is the so-called "dual antenna design".

Expand the soft antenna for measurement, and the length is about 85cm. The length of the antenna determines the scalability. The length of nearly 1 meter is enough for any placement.

The deployment length of the Micro USB power adapter is about 120cm, which is not only long, but also thick enough. The details of this line can be seen more clearly under the digital microscope.

AWM 2725 28AWG/1PR+26AWG/2C 80℃ 30V VW-1SC FT1 HUAWEI：

AWM PVC insulated coaxial cable consists of a pair of 28 gauge twisted pairs and two 24 gauge straight wires. Because twisted pair has good anti-interference ability, it is usually used as signal data line. There are two data lines and two transmission lines in the USB line, so 1P is usually data line, and 2C is transmission line. The rated temperature of this line is 80 ℃, the rated voltage is 30V, and it can pass the VM-1SC vertical flame resistance test.

Note: VW-1： The fire protection standards VW-1 and VW-2 are UL flame retardant grades, representing that such wires are not easy to burn. Generally, there is no such mark on domestic lines.

MOZART uses natural walnut wood as the box material, with golden panel and solid keys, which is full of retro style. According to the measurement, the thickness of the walnut frame part of the fuselage is about 3.86mm.

The fuselage is about 117mm long, 63.25mm thick and 60mm high. This volume can be counted as mini. Although it seems small, the weight is not light. After weighing, the weight of MOZART is nearly 400g.

Let's take a closer look at the design details of MOZART. There is a very obvious word "Mozart" on the metal mesh cover on the left side of the front. In addition to a 40mm NdFeB magnet horn, there is also an indicator light covered by the mesh cover.

Tips： Nd-Fe-B magnet is a kind of artificial permanent magnet, which has the strongest magnetic force so far. It is predicted that in the next 20 years, there will be no magnetic materials to replace Nd-Fe-B magnets. The main raw materials for producing Nd-Fe-B magnets are rare earth metal neodymium, rare earth metal praseodymium, pure iron, aluminum, ferroboron and other rare earth materials.

The right side is the FM display area and the entity key area.

The left side of the back is the jack area, including the external antenna AUX、 And charging interface.

Here on the right, according to the instructions, the professional term is passive speaker, which translates into passive speakers. This part is about 67mm long and 34mm wide.

Four rubber feet are designed at the bottom corners of MOZART, which can effectively protect the product from wear. According to the contents of the sticker in the middle, we can have a deeper understanding of this product. Similarly, according to the above content, the matching data was found in various professional institutions.

3、 Test:

1. Charging:

This is the effect picture recorded when using the QC3.0 charger. The voltage remained between 5.140V and 5.139V, and there were several small fluctuations during the charging process. The battery capacity detected by the equipment is 2350mAh, and the average voltage is 5.12V. It can be seen from the figure above that at the beginning of charging, the charging current was small, only about 0.05A. After more than 10 minutes of charging, the current rose to 0.45A at the highest. Then it fell back to 0.35A, rose again to about 0.45A, and finally entered a stable charging state. After nearly 5 hours of charging, it began to enter the trickle mode, and was fully charged in 5 hours and 57 minutes.

Note: The 2350mAh high capacity lithium battery is officially said to play Bluetooth for more than 20 hours after full charge, and more than 60 hours in radio mode. God knows what I experienced when I used up its power

2. FM:

The FM range is FM87.5-108MHZ, which is the same common frequency range as traditional radios. When starting up, the panel will light up the orange background light, and you can select the station directly through the knob.

Through the radio test, I feel that the sound quality of this MOZART is very balanced, and it sounds very comfortable to my ears.

3. Bluetooth:

After the Bluetooth connection is successful, the headset icon can be seen in the upper right corner of the phone screen. The words [Connected] can also be seen on the Bluetooth interface.

However, it is a pity that the remaining power of the speaker cannot be controlled through the mobile phone screen. It is hoped that this problem can be valued and improved in the follow-up products of Shanjin.

4、 AUX IN：

//v.youku.com/v_show/id_XMzE1NTYxNDk5Ng==.html?spm=a2h3j.8428770.3416059.1

//v.youku.com/v_show/id_XMzE1NTY5NTU0NA==.html?spm=a2h3j.8428770.3416059.1

//v.youku.com/v_show/id_XMzE1NTcwODg2MA==.html?spm=a2h3j.8428770.3416059.1

After connecting the mobile phone and the speaker through the audio cable, I recorded 5 audio test videos (including the first one at the beginning of the article), which sounded completely free of resonance noise, and the sound was relatively balanced. The control of sound is appropriate and explosive.

4、 Summary:

I like radio, and I like the feeling that I can only hear the sound but not see the person. Before the promotion of TV, radio had a good time with our generation of post-80s generation. When I was a child, my grandmother listened to the program with [talkbox] in her arms for a long time now.

The retro style has always been a feeling. I always believe that the most valuable thing is not money, not fame and wealth, but memory. As long as memory exists, we will not live in vain.

When the retro wind and the radio collide together, the sparks generated must be bright and eye-catching. In this respect, Elvis series is a very good proof.

Shanjin's MOZART has its own merits both in appearance design and sound quality. Even a small data line is so perfect. But what struck me most was its endurance. It's hard to imagine that such a small radio could last so long. If you also like the retro style, and there is no such tasteful product as MOZART in your home, please take the time to own it to ensure that you will not be disappointed.
