我们生活在一个美好的科技时代。我们拥有：无线充电^{(wireless charging)}、3D 打印、增强现实，以及各种在十年前听起来就像科幻小说的技术。^{(science fiction)}如果您想不断提醒我们这个时代有多酷，那么没有什么比我们今天正在审查的设备类型更有吸引力的选择了：它可以无线连接到您的移动设备，播放您最喜欢的曲调，并在旋转的同时做到这一点缓缓的在半空中。在您的办公桌上放一个Tec + Dynamo Levitating Bluetooth speaker感觉如何？继续阅读此评论以了解：

拆箱Tec+ Dynamo Levitating Bluetooth Speaker

与往常一样，任何严肃的测试都从适当的拆箱^{(roper unboxing)}开始。Tec+ Dynamo Levitating Bluetooth speaker采用立方盒子，没有任何华丽的设计或透视窗。手柄和蓝色标签指出了设备的一些规格，是唯一从平淡的棕色纸板箱中^{(cardboard box)}脱颖而出的东西。

蓝牙范围^{(Bluetooth range)}，最长十米（蓝牙^(Bluetooth)应用的标准范围），播放时间，最长五个小时（似乎有点短），蓝牙版本4.0^{(Bluetooth version 4.0)}（新标准，不错）。只是基础知识，但它确实是一个非常简单的设备，因此您现在不需要其他信息。该设备采用聚苯乙烯泡沫塑料紧密包装，这意味着它在运输过程中应能经受住不小心的处理。

在包装内，您会找到基座^{(base unit)}、扬声器、定位工具^{(positioning tool)}、基座的AC^{(base unit)}适配器^{(AC adapter)}（电源）和用于为扬声器充电的 micro-USB 电缆。还提供了一个很小的用户手册，其中涵盖了正确操作设备所需的所有信息。

我们的设备带有一个三刃交流适配器^{(AC adapter)}插头（G 型^{(Type G)}，在英国和其他几个国家使用）。在购买设备之前，请^(Please)与您的供应商确认交流适配器^{(AC adapter)}插头的类型。

结构和硬件规格^{(Construction and hardware specifications)}

底座的直径为 5.9 英寸（15 厘米），高 0.8 英寸（2 厘米），而球体的直径为 3.5 英寸（9 厘米）。电源线长 5.5 英尺（1.7 m），足以将底座单元^{(base unit)}放置在桌子上。底座只有一个用于电源连接的插座，而扬声器有一个On/Off button和一个用于充电的微型 USB 插座。

基本单元^{(base unit)}的边缘有一个蓝色LED 环，而扬声器有一个蓝色^{(LED ring)}LED 带^{(LED band)}和几个红色LED^{(LED s)}，当设备处于配对模式时它们会闪烁。

扬声器规格^{(speaker specs)}对发烧友来说并不令人鼓舞：扬声器驱动器尺寸^{(speaker driver size)}仅为 1.6 英寸（4 厘米），信噪比^{(signal-to-noise ratio)}为 80 dB，连续 ( RMS ) 功率为不起眼的 3 W，而频率响应从理论上讲，150 Hz - 20 kHz 的范围^{(frequency response range)}听起来不错，但这种尺寸的扬声器不太可能有很多低音再现^{(bass reproduction)}。但我们将在下一节中讨论。

该设备使用蓝牙 4.0^{(Bluetooth 4.0)}，但与同类产品不同的是，它没有NFC 功能^{(NFC capability)}。那么电池消耗^{(battery drain)}应该不是问题，对吧？错了^(Wrong)。根据规格，播放时间^{(play time)}最长可达 5 小时，许多类似产品声称电池寿命^{(battery life)}在 10 小时范围内。最重要的是，充电需要很长时间，长达 3 小时。

（相当平淡的）产品页面在^{(product page)}网上^(Internet)真的很难找到，但经过一番仔细搜索，我们找到了它：Dynamo 悬浮蓝牙音箱^{(Dynamo Levitating Bluetooth Speaker)}。现在让我们进入有趣的部分^{(fun part)}，实际测试。

The Tec+ Dynamo Levitating Bluetooth Speaker Review - The Death Star of speakers!

We live in a wonderful age of technology. We've got : wireless charging, 3D printіng, аυgmented reality, all sorts of technologies which would haνe sounded like science fiction even a decade ago. If уou want to be constantly rеminded of just how cool our tіmes are, there are few alternativeѕ more appealing than thе type of device we're reviewing today: it connects wirelessly to your mobile device, it plays your fаvorite tunes and does that while spinning slowly in mid-air. How would it feel to hаve a Tec + Dynamo Levitating Bluetоoth speaker on your dеsk? Keep reаding this review to find оut:

Unboxing the Tec+ Dynamo Levitating Bluetooth Speaker

As always, any serious testing starts with a p roper unboxing. The Tec+ Dynamo Levitating Bluetooth speaker comes in a cubic box without any flashy design or see-through windows. The handle and the blue label, pointing out a few specs of the device, are the only things that stand out from the bland, brown cardboard box.

Bluetooth range, up to ten meters (standard range for Bluetooth applications), play time, up to five hours (it seems a bit short), Bluetooth version 4.0 (new standard, that's good). Just the basics, but it's really quite a simple device, so there is no other information you would need for now. The device is tightly packed in styrofoam, which means it should survive careless handling when in transport.

Inside the package you will find the base unit, the speaker, a positioning tool, the AC adapter (mains supply) for the base unit and a micro-USB cable for charging the speaker. There is a tiny user manual supplied as well, which covers all the information required to operate the device properly.

Our unit came with a three-blade AC adapter plug ( Type G , used in the UK and several other countries). Please check the type of the AC adapter plug with your vendor before you buy the device.

Construction and hardware specifications

The base has a diameter of 5.9 inches (15 cm) and is 0.8 inches tall (2 cm), while the orb has a diameter of 3.5 inches (9 cm). The mains supply cable is 5.5 feet long (1,7 m), enough for positioning the base unit on a desk. The base only has a socket for mains connection, while the speaker has an On/Off button and a micro-USB socket for charging.

The base unit has a blue LED ring on its edge, while the speaker has both a blue LED band and a few red LED s , which blink when the device is in pairing mode.

The speaker specs are not encouraging for an audiophile: the speaker driver size is only 1.6 inch (4 cm), the signal-to-noise ratio is 80 dB, the continuous (RMS) power is an unimpressive 3 W and while the frequency response range of 150 Hz - 20 kHz sounds good in theory, it's unlikely a speaker this size will have much bass reproduction. But we will get to that in the next section.

The device uses Bluetooth 4.0, but unlike similar products, it has no NFC capability. The battery drain should not be a problem then, right? Wrong. According to specifications, play time is just up to 5 hours, with many similar products claiming a battery life in the range of 10 hours. On top of that, charging takes a long time, up to 3 hours.

The (rather lackluster) product page is really hard to find on the Internet, but after some careful searching, we found it: Dynamo Levitating Bluetooth Speaker. Now let's get to the fun part, the actual test.
