Sound quality experience

Introduction

With the continuous development of science and technology, sound, as a sound playing tool, is widely used in people's life and work; In the living room, park square, office or some leisure places at home, you can see all kinds of sound systems. People use them to listen to music, radio, and cultivate their feelings and relax. Throughout the market, most of the audio products are deliberately pursuing appearance and appearance, but they do not really pay attention to the sound quality effect, which makes many consumers feel confused when buying audio products; Xiao Bian believes that only with such factors as excellent sound quality, beautiful appearance, powerful and practical functions can they be competitive in the market of similar products and be favored by consumers.

Today's small editor brings you the Theme Box sound, which is made by Designed by the Acemile team in California, USA, it is a panoramic audio system created with the idea of subverting the traditional audio quality in the market and bringing new audio effects to users. Q3D full scene sound is a kind of Virtual 3D sound effect technology based on sound field wave synthesis. It simulates the diffracted sound wave that synthesizes the highly restored natural sound effect, and has the advantages of small sound generating surface, wide propagation range, high separation, and strong sense of time and space. The Q3D panoramic sound enables the listener to experience the 3D sound effect in any position around the device; The appearance of the product does not have too much embellishment and decoration. The seemingly simple shape has a good beautiful effect in terms of hearing. Is the practical effect of this stereo the same as that introduced by the editor? Next, let's go into this evaluation trip together with our editor.

Open box display

The sound of the Theatre Box is packaged in a relatively elegant black gift box. The front design of the box combines the famous work of the great painter Van Gogh, "Night of the Stars and the Moon", in which the element of a music conductor in the countryside is added, making the whole product look very classical and dreamy; On the back of the box are several shell colors of this product and a brief introduction on the lower left corner. What Xiaobian got is a blue style, which is very artistic.

Thanks to Lei Feng.com for giving me this valuable evaluation opportunity. The side of the packaging box is printed with the product name "Theme Box". The hardness of the packaging box is also relatively strong, which can effectively prevent accidents such as collision during product transportation.

Different from the flip open mode of traditional products, Theatre Box The drawer is pushed and pulled. Although the inner shell is designed with a handle made of blue woven fabric, due to the weight of the stereo, it is not very useful to take it out; Xiao Bian suggested adding a hidden semicircle handle on the side of the inner shell to better facilitate users' unpacking. What's more intimate is that the upper part of the stereo is covered with a thick layer of hard foam for protection.

Take out the audio head unit and see that the rest of the accessories are placed in a layered layout. There is also a layer of foam partition structure at the bottom of the audio, which not only maximizes the use of space resources but also makes the visual effect more uniform.

In addition to the audio itself, the accessories section also includes a power adapter, power cord, Aux3.5mm audio cable and instruction manual. It is worth mentioning that the rated output parameter of the power adapter is 15V/3A, which is different from the 12V and 18V output parameters of the smart audio products we usually contact.

The user manual gives a detailed description of the function and structure of the audio system, operation methods, precautions for use, and relevant parameters and performances. Although they are all in English, they can understand the meaning even if they have a little English knowledge. The editor suggested that you should read carefully before use. After all, the use method of the Theme Box stereo is unfamiliar to us. After careful reading, you can avoid misoperation during use.

The front, back and side of the audio are displayed. In order to help people better understand this product, the editor summarizes the main parameters as follows:

Net weight: 1.6kg

The Theme Box audio adopts a 360 degree blue perforated iron mesh surround scheme for the main body, with the control panel of piano painting plastic process on the top of the body. The appearance is full of metal, very delicate and full of science and technology. The shape and structure of the sound system adopts the traditional regular cuboid shape, and with a weight of 1.6kg, it looks three-dimensional.

Detail display

The front and bottom of the fuselage is the logo of American manufacturer Acemile, but because of the integrated blue fuselage, the visual effect is not very prominent. It is suggested that you can match some contrasting colors to set off the logo and make it more conspicuous.

The control panel on the top of the fuselage contains six capacitive touch buttons: phone key, mute, previous song, next song, volume down, and volume up. On the far right is NFC direct connection matching. The white key logo is evenly and symmetrically distributed in the center of the panel, which is quite fashionable and artistic.

At the bottom of the back of the fuselage are the power key, Bluetooth key, power interface and 3.5mmAux audio input interface. Unfortunately, the Theme Box The audio does not have a USB interface and does not support the audio file reading function of hard disk storage devices. In order to make the user's use environment more diversified, it is recommended to add this function so that the audio can work without the audio source playing equipment.

The perforated iron mesh in front of the fuselage adopts the top metal sandblasting process, on which numerous small sound holes are densely arranged, ensuring the best sound release and transmission as well as the beauty.

The overall streamline of the sound system is very beautiful. At the same time, arc chamfer structure is used at four corners, which not only increases the use safety factor, but also makes the visual effect more beautiful than ordinary rectangular shapes; As you can see, the contact connection between the punched iron mesh and the audio host is also highly closed, and there is no large gap.

Theatre Box A whole rubber anti slip pad is set at the bottom of the, which also adopts the blue color integrated with the fuselage, which can be said to pursue the ultimate in details. Large area rubber pad In addition, the 1.6kg weight of the audio itself can be stably placed on any desktop, tea table, bedside table and other environments, without fear of sliding and toppling.

The label on the bottom of the audio provides the output voltage parameters and information introduction, which reduces the trouble of reading the user manual again. The details are very user-friendly.

Although the size of the audio system has been described in the previous parameter introduction, in order to give you a more intuitive understanding, I will actually measure it with a scale. The height and width of the stereo are 110 mm and 85 mm respectively. Because the scale scale range is not enough, the length cannot be measured.

Use display

One of the highlights of the Theme Box audio system is its acoustic unit structure, which includes four 2-inch full audio speakers around the speaker and a 3-inch active bass speaker behind it. Different from the limitations of traditional dual channel sound wave transmission angle, the four units of the Theme Box can achieve sound wave transmission of approximately 360 degrees. So that no matter where you stand around the speaker, you can feel the same sound effect and experience a good sense of space and orientation.

The Theme Box audio can play audio files directly with mobile phones, tablets and other audio source devices through Bluetooth 4.0. When the connection is successful, during playback, and when the connection is disconnected, the audio system will display English prompts such as connected and battery low, which is very simple to use.

The distance between the capacitive touch keys is reasonable, and the other function keys on both sides will not be easily touched by fingers; The sensitivity is also quite satisfactory. However, the editor found that the product lacks independent hardware keys for fast forward and fast reverse of songs during use, which can only be adjusted through mobile phone software. This is somewhat inconvenient, and it is recommended to increase it later.

Each button has sound light synchronous feedback. When touching, the LED light at the bottom lights up continuously for 1-2 seconds, which is very humanized design. In addition, the button also supports the long press function, which can save the trouble of touch when the volume is increased or decreased.

The outer circle of the power button is equipped with an LED working status indicator, There are red and white color changes , press the Bluetooth key when starting up, the light will continue to flash red and white alternately to enter the playing device pairing state; In the process of playing, the LED is always white; When the audio power is too low, there will be a red light prompt. By the way, here The built-in battery of the Theme Box audio, 2600 mAh lithium battery, can provide about 20 hours of battery life, and it takes 4 hours to fully charge; Xiao Bian personally played the test. Although it did not reach the rated time of 20 hours, the difference was not much, and the result was very satisfactory.

The AUX IN connector on the back of the audio can be connected to a 3.5 mm audio cable, which can be connected to computers or tablet phones for audio playback; Because many desktop computers do not have a Bluetooth module, this has a great effect on the direct audio cable.

Outdoor display

Because of its built-in high-capacity battery and moderate size, the Theatre Box stereo is not only an indoor audio and video player, but also can be carried outdoors for use, breathing natural fresh air and listening to the moving melody with excellent sound quality. It must be a way to enjoy life.

Xiao Bianyi is carrying The Here Box takes outdoor photos, but most of them also take a walk in the park on weekends, watching the unique scenery of dead leaves flying and snow not melting, sitting quietly to listen to some gentle songs and bathe in the early winter sunshine.

When I came to the study room on the campus, I found no hard working students in the empty classroom, so I gently tested the indoor playing effect of the sound. No matter from the sense of position of the instruments in the song, the sense of hierarchy of the frequency and other aspects, the minor editor is very satisfied. Because it is a public place for learning after all, the sound of the stereo is relatively low, and I am afraid that I will be complained about, so I left in a hurry without many meetings.

Come to the school playground and sit on the ground to experience the outdoor experience of audio; The editor played several prairie songs and closed his eyes to listen. Tenger's Paradise really seemed to bring people to the vast prairie. At the front of the post, the editor also recorded a video of this song, and I hope you can appreciate it together.

summary

Sound quality experience

Cheerful: Beautiful ones、young for you。

The bass is sinking, the mezzo level is obvious, the vocal part is clear, the treble is slightly inadequate, and the overall atmosphere of the song is also good.

Classic audition songs of hotels and ferries in California

At the beginning of the drum beat, the California Hotel turned up the volume, and the effect was still great. After the whole song, I think that Theatre Box In terms of performance, it is still good. The sound field is slightly narrow, and the mid-range sense of hierarchy is slightly less. The position and orientation of several instruments in the California Hotel are obvious.

Female voice: Holiday、last Christmas

so to speak Theatre Box The performance of our girls is quite good, holiday， The female voice field is also wide, and you can hear many details.

As for the evaluation post of the Theme Box audio, the editor has brought so many things to you. There may be some things in the article that are not detailed or comprehensive. Please give more criticism and correction. In general, the Theatre Box audio has killed many similar products in the market because of its beautiful appearance and outstanding sound quality; However, during the evaluation process, Xiaobian also found several shortcomings of the product, which are summarized as follows. I hope the manufacturer can consider the suggestions of Xiaobian.

1. No USB interface is set for the audio. It is recommended to add the direct play function of hard disk storage devices so that the audio can be used independently from the audio source player.

2、 The Theme Box audio product itself does not have a fast forward and fast backward operation button for music tracks. It is recommended to add this button. Otherwise, it can only be operated through the playback software every time, which is very inconvenient.

3. Although the integrated color scheme of audio is fashionable and personalized, it still lacks some intrinsic theme elements of the product, and hopes to integrate some into it.

4. The playability of the audio system is relatively low. It is recommended to add WiFi modules or voice modules to enable dialogue and interaction with users to make it more vivid.

5. Add the storage function of the fuselage itself, so that users can download favorite music files and store them in it, so that they can play them at any time even without connecting external devices.

6. It is suggested to add a handle structure to the product packaging box. A colored belt does not play a much role in unpacking.
