A | 蓝牙黑带录音机不是什么新鲜事，但你见过黑带扬声器吗？最近，一个来自国外的小弟弟发布了这个产品，并筹集了大量资金。 New Delhi, Oct 12 (UNI) The country's fourth semi-high-speed intercity train, Vande Bharat Express, will operate between Delhi and Una in Himachal Pradesh from Thursday.
It will be connecting Sikh shrines like Kiratpur Sahib and Anandpur Sahib in Punjab and shrines like Mata Jwala Devi and Mata Chintpurni.
Prime Minister Narendra Modi will launch it from Una on October 13. And then Railway Minister Ashwini Vaishnaw will take the maiden ride to New Delhi in the same train.
On September 30, the third Vande Bharat Express was started between Gandhinagar and Mumbai. Modi then had taken a ride between Gandhinagar to Ahmedabad.
The third and fourth rakes of Vande Bharat Express have been manufactured at the Integral Coach Factory (ICF) located in Chennai.
Upgraded from the first version, the EMU vehicle of this version is capable of attaining over 180 kmph speed.
Una, an industrial town bordering Punjab will get a big boost.
Haryana, Punjab and Himachal Pradesh as well as the Union Territory of Chandigarh will also benefit from the running of this train.
It is believed that the fourth VBE train, which will travel 385 km, will be popular among the passengers.
UNI XE ING。黑带只是一个很薄的乙烯基，怎么能做成蓝牙扬声器呢？这并不复杂。
B | 首先，弟弟用乙烯基作为吸音板——也就是说，整个黑带唱片作为扬声器的底座，唱片的背面是集成的驱动单元和蓝牙组件。其次，黑胶在发声时会与音乐声波产生共振，唱片的形状特征可以使声音传播更加均匀。这意味着声场和音量从上到下几乎是一样的。此外，为了减少共振，除了将记录本身作为支架的一部分，它还提供了一个完全透明的支架。当你发出声音时，你可能会看到碟片在晃动，但因为这三点支持你，你不能说你不想让唱片在桌子上“跳舞”。
C | 同时，黑色是全彩色的，所以它在房子里的任何地方都不显眼。蓝牙扬声器内置800毫安锂离子电池，正式使用时间约为6小时。最低价约623元。你会买吗？。
