The emergence of Bluetooth speakers has freed the speakers from the shackles of wires and optical fibers. The portability it brings makes them a good companion for music lovers to march outdoors. In recent years, the addition of smart cloud and WIFI audio has given wireless speakers more options, but Bluetooth speakers still have room for survival. The author here recommends an ACEMILE portable wireless speaker, the Theme Box, which breaks through the traditional music sound technology and surprises the North American market with its Q3D panoramic sound technology. This speaker has recently entered the domestic market and is crowdfunding at a retail half discount in JD, which has attracted the attention of many music lovers.

As a 1000 yuan portable speaker, the biggest difference of the Theme Box is that it does not have too many entanglements in traditional HIFI, but achieves a virtual 3D sound effect through self-developed Q3D halophony technology. Unlike the traditional 3D sound effect technology, Q3D full scene sound no longer depends on the combination sound system to create the psychoacoustic illusion of sound source perception, but on the physical reconstruction of sound field waves. Let the listener feel the same virtual 3D sound effect at any point around the device. Thanks to Lei Feng's trial platform for giving Bug this experience opportunity, can this product attract users' purchase desire?

Theatre Box The packaging style is European and American, and the famous painter Van Gogh's "Night of the Stars and the Moon" on the box only adds the silhouette of the music conductor, making this classic famous painting more dreamy.

The Theme Box sold in China this time has four versions: black, red, blue and white. The blue version is used in this trial. The retail price of the product is 1999 yuan, and crowdfunding users can enjoy a half discount of the ultra-low back price, which should be very worthwhile.

There is a layer of casing on the outer package. In order to make it easy for users to take it out, the manufacturer carefully added a blue woven belt pull ring on the inner box.

The manufacturer pays enough attention to the protection of the products. The materials are sufficient and the outer packing box is very thick, so there is no need to worry about the damage to the products during transportation. In addition, there is a layer of foam pad on the top and bottom of the speaker for protection. From the holes on the foam pad to the blue braid covered outside the speaker box, which is convenient to take the product out of the box, the author really likes the humanized design of the manufacturer when thinking of the blue braid outside the inner box. The lower layer of the inner box hides the accessories and instructions attached to the product.

In addition to the Theme Box, accessories include: 15V 3.0A power adapter, power cord, product insurance certificate and instructions, and an AUX3.5mm audio cable.

Theatre Box The long square box design is adopted, integrating the simple and plain design style of Europe and the United States, and the blue color is integrated. The size of the fuselage is 260mm × 85mm × 110mm, and the weight is 1.6Kg, which is sufficient. The upper and lower parts of the fuselage are made of plastic material, and the metal texture is full after being treated with similar metal paint. The metal grid is surrounded in the middle. The overall workmanship is very fine, which is in line with the technological level of this price.

The top is equipped with flexible capacitive touch buttons, which are respectively for teleconference, mute, previous song, next song, volume reduction and volume increase. In addition to Bluetooth connection, the Theme Box also supports NFC direct connection. Each touch button is equipped with LED light, which will light up for 1 or 2 seconds after the button is pressed.

At the lower back of the body are the power key, Bluetooth key, power interface and 3.5mm audio interface. It is a pity that the Theme Box does not support SD card reading. The power key is equipped with a red and white LED indicator. When the Bluetooth key is pressed in the power on state, the light will flash intermittently in red and white to enter the pairing state. When the battery is low, it will also be displayed in red.

The built-in 11V 2600 mA lithium battery can guarantee 20 hours of high tone endurance, and it takes about 4 hours to fully charge the battery. There will be a voice prompt when the battery is insufficient or fully charged, but the power indicator will not go out or change color after the battery is fully charged. This design is slightly inadequate.

The bottom of the fuselage is a large anti-skid rubber pad, which also adopts the same blue color matching with the fuselage. There are several slightly raised feet on the rubber pad, and the middle one is the product information.

In order to achieve the ultimate sound performance, four full audio speakers and an active bass speaker are integrated into the four sides of the audio system. Compared with traditional dual channel speakers, the advantage of this is that the range of sound will be significantly wider, and no matter where you are in the speaker, the sound effect will not be affected. This acoustic architecture, coupled with the dual core digital circuit drive of virtual 3D sound effect, can match the sound effect of traditional home theater ensemble. The panoramic sound field can cover 150 square meters, and even the largest living room can be held.

If you have a portable intelligent projector and a Theme Box, it is perfect. Bluetooth 4.0 connection allows you to experience 360 degree surround sound without connecting any audio cable. Here, the author suggests that if you have a Theatre Box, you must put it in the middle of the house, so that the whole room can enjoy the sound effect of the cinema without dead corners.

Due to the combination of 4 full frequency units+1 active bass, the overall tuning of the Theme Box tends to be low mid frequency, while the performance of treble is slightly inadequate. A California Hotel. Although the drums in the first part didn't dive deep, the audience's applause and whistles can tell the advantages of this speaker. It has a great sense of spatial hierarchy and a wide sound field. The high frequency performance of guitar, SOLO and voice is not clear enough.

Summary:

Theatre Box Instead of pursuing HIFI sound effects as many speaker brands have, they have transferred technology to full AV 3D sound effects, thanks to unique acoustic architecture and their own Q3D panoramic sound technology. It can bring excellent stereo surround sound effect to people whether in viewing or music. The overall workmanship of the speaker is solid and fine, and the packaging reflects the hard work and humanization of the manufacturer everywhere. If the Theme Box can be read with an SD card, the portability will be more prominent. If the Theatre Box can stabilize high-frequency tuning, maybe this speaker can get more support from enthusiasts.
