Like many people, I am also a music lover and will listen to music in my spare time or under certain circumstances; Either relax your nervous system or cheer yourself up. It is because of music that our spiritual world can be full of freedom and reverie. When I first saw the [Phantom Xiaobei Sound] on Lei Feng.com, it was just a gadget. I didn't expect Xiaobei to be very small!

When I received the goods, I got such a big package. I wondered if it was Xiaobei? As a result, take a look, oh ho! This is not a "small" shellfish. It's obviously a big shellfish;

Xiaobei, wrapped in a plastic bag, can't hide his white body even though he wants to talk about giving up. Hehe~

The accessory parts are very simple, One 9V power adapter and one AUX audio cable;

The user guide, warranty card and certificate are also available;

The overall shape of [Miraculous Xiaobei] is just like its name, like a white shell, and the central sound hole is like a round pearl, which makes people really love it; and The heavy feeling of being in the hand also makes people cry "good" for its work and materials!

Three touch keys are simple and easy to use. Long press and short press have different functions respectively, so that the whole machine body has no complicated feeling and complements the white appearance.

【 The design of this hidden interface and buttons is similar to the clam shell micro opening, a pair of sample paper that needs to be explained, including an open key POWER, a 9V power adapter socket DC 9V, an AUX audio socket and a mode button MODE.

Xiaobei's loudspeaker adopts a short wool fiber composite paper basin. Right above is a 2.5 inch low frequency speaker, Two 1.5-inch full range speakers are arranged on the left and right, Below are the passive units - two passive radiators. The so-called "passive radiator" is actually It is a paper basin, not connected with any voice coil or circuit; The passive radiator is usually used to adjust the bass, which is used by the speaker designer to adjust the overall voice color of the speaker. It makes a passive sound under the driving of the active unit in the speaker to the air in the box. This all-round 360 ° sound generation design makes Xiaobei's aura very strong when playing music; At the same time, Xiaobei's parsing chip uses the nuvoton NPCA110P audio enhancement engine, which uses 24bit high precision ADC and DAC. The timbre dialysis power is very good, especially when playing jazz drum percussion instruments, hold a piece of paper Above the sound hole You can see the trembling of air waves.

Xiaobei's control is very user-friendly. There are voice prompts for Bluetooth connection and mode switching. When playing music, the sound hole light remains on; After the Bluetooth connection is disconnected, the LED flashes until the connection is successful again. When using the audio cable for direct connection, it is very convenient to connect Xiaobei's AUX interface to his mobile phone, laptop, MP3/4/5 or computer. This configuration of [Mirage Xiaobei] is applicable to many scenarios, such as:
1. Student Party.
In the boring and tired study room, a group of students are immersed in the whole pile of materials; Suddenly, Xiaobei Phantom sang a happy youth dance in the corner of the classroom. The excellent sound quality made the students uncontrollably forget themselves. They forgot about Yalishan and all their troubles for a while. At this moment, there was only happiness
2. Overtime dog.
The night was deep, and several office workers stared at the flickering computer screen gloomily; At this time, a beautiful violin sound came out from behind the curtain, and everyone was fascinated by the penetrating timbre in the night, which was the atmosphere created by [Phantom Beckham]
3. Hikers on field trips;
4. Couples for candlelight dinner;
    …………

HIFI audition music stored in the computer is used to test the effect of "Phantom Beckham". From the test disc, we can feel that Xiaobei's low-frequency dive is good but not enough. This is also the shape limitation; However, the performance of its mid-range voice is relatively in place, and the front position makes people feel as if they are on the scene and in the spring; At high frequencies, the tuning level is clear, the information is rich, and the brightness of the voice is also well grasped. Due to its portability and cost performance, it is inevitable to give up a lot of control over the audio quality of the Bluetooth speakers The performance level in tri frequency is good, and the transition is very smooth, especially the low frequency stability is well grasped in similar products.
