The sound effect recording technology of movies has made a great leap in recent years, that is, panoramic sound recording has become the norm. The richness and shocking effect of panoramic sound effect are developed together with 3D and holographic images, which makes the appeal of film audio-visual reach an unprecedented level. Every time the development of film sound effect recording technology has also brought about the evolution of music recording and music style. For example, Tencent's QQ Music recently launched the full scene MP3 music of the Voice of China series. The era of panorama sound has come. Have you ever known about panorama speakers?

1. The world's first portable 360 degree 3D surround sound box;

2. Amazon Black Five American Surround Sound Single product sales champion ；

3. Digtal Trends, Audio&Vision and Gizmag, the professional media in the United States, all made detailed independent evaluation reports. Digital Trends, which is famous for its preciseness in the industry, rated the Theme Box as 4 stars. This rating is the same as BOSESoundlink 2, and higher than Harman Kardon Onyx's 3.5 star rating.

4. Herbert Waterer, the pioneer of 5.1 sound effects who won Grammy Award for several times, also said: "Its sound effect reproduction ability is amazing. Integrating such exquisite skills into such a simple design, The Box is undoubtedly a breakthrough."

The Theatre Box Q3D audio with the aura above the head was released by ACEMILE, a start-up enterprise headquartered in Sunnyvale, California, USA, which focuses on the development of wearable devices, and amazed the North American market with its Q3D panoramic sound technology. The product entered the Chinese market in November, and currently participates in crowdfunding in JD, with a tentative retail price of 1999 yuan. The lowest price of crowdfunding is 899 yuan (the quota is full). It's a great honor to have successfully adopted one on the 72 variable intelligent hardware recommendation platform. Thank you very much! Follow the editor to see how Q3D performs.

As a sound evaluation article, I always think it is not appropriate to use some photos and words to interpret it. If you are a consumer or potential user, you always want to hear it intuitively. However, the embarrassment is that the small editor has no professional recording equipment. Even if there is, it is difficult to experience the real effect of the box after recording and uploading to the network for compression and transcoding. However, the performance of the Q3D audio system has exceeded the expectation of the editor, so I resolutely recorded several videos on my mobile phone and put them on, hoping to give you a slightly intuitive feeling. Q3D audio will soon be sold in offline stores in China. I suggest you go to physical stores to listen to it if you have the opportunity.

First, let's popularize the Q3D panoramic sound technology

Let's take a look at the basic parameters of today's protagonist

On the other side of the box is a product picture printed with four colors, black, red, blue and white.

There is a blue ribbon pull ring on the side of the box, through which users can easily pull out the audio. There is a thick sponge pad at the top and bottom, and there is no vacancy in the middle. It is well protected and safe during transportation. There is also a blue "belt" in the middle of the audio. If the audio is 1.6KG, it is hard to take it out without this belt. The design is very considerate.

Product functions and details

The Theatre Box is in the form of a long square box, integrating the simple and plain design style of Europe and the United States. It is surrounded by metal grids and covered with plastic panels. In front of the audio, there is only the logo stamped by the brand "ACEMILE", which is very simple.

At the lower back of the body are the power key, Bluetooth pairing key, charging power interface and 3.5mm audio interface. 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, and there will also be voice prompts (for voice prompts, there is a phone call, and there will be voice prompts when the battery is low or fully charged, but the small editor receives a foreign version, and the prompt tone is in English).

Smart capacitive touch buttons are used on the top of the audio system, including answering and making calls, 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 backlight, which will light up for 1 or 2 seconds after the button is pressed.

The bottom of the machine body is a piece of anti-skid rubber pad, which can not only play the role of anti-skid, but also effectively prevent the resonance between the sound and the table. There is also a product information label in the middle.

Accessories include: 15V 3.0A power adapter, power cord, product certificate and instructions, and an AUX3.5mm audio cable.

This AUX audio cable adopts the popular flat cable, and the quality and workmanship of the gold-plated plug are good.

Audition feeling

This speaker uses Bluetooth 4.0 communication and NFC direct connection matching. To ensure the lossless transmission of sound quality, it also introduces the aptX transmission protocol of CSR. Parameter configuration: 2-inch full frequency unit × 4, 3-inch bass unit × 1, power output: standard/56W; Peak value/125W, sound effect technology: Q3D panoramic sound, frequency response range: 20~20000Hz, SNR: 90 dB, sensitivity: 90dB @ 1KHz @ 1m, input sensitivity:<600mV.

When the editor used a lossless music player to connect to the Q3D audio for the first time, its performance made my eyes shine. It's really not an ordinary portable case. So the volume was increased to the maximum, and no pop was heard, and the sound field performance was normal. I couldn't help thinking of the official slogan: the panoramic sound field can cover 150 square meters, and even the largest living room can be held! in truth.

It has a built-in high-density lithium battery, which can ensure that the speaker can play at high volume continuously for more than 20 hours without external power supply. It is very suitable for carrying out use. Based on the style of pragmatism, the Feature Box also retains the function of Bluetooth teleconferencing on the speaker. This may not be a necessary choice for philharmonic, but it is also helpful for the younger generation and SOHO office workers. Just imagine that on the weekend, we asked our friends and two families to drive to the outdoors for an outing. The adults sat and talked while the babies played football and threw frisbees. At this time, the Q3D audio system is playing the light music of Bandari or the collection of children's songs that babies like. The panoramic sound of Q3D, no matter where you are, is heard by your left ear as well as my left ear. With a 20 hour endurance, there is no need to worry about the embarrassment of insufficient power.

Summary

Xiaobian connected to the Q3D audio system through mobile phones, lossless music players, computers and televisions, and performed commendably in all aspects. In particular, the Q3D panoramic sound allows you not to think about the placement of the sound. The small editor's TV has always used the E225 speaker of the rover magic number, and hereby made a comparison with the Q3D sound. In fact, the cinema effect of Q3D is stronger than E225. But the only disadvantage is that the sound of Q3D is slightly dull compared with E225. However, the portable size of 260 x 85 x 110 mm, the super long 20 hour endurance and the unique Q3D panoramic sound technology can also be said to have more than their flaws.
