Light bulb online? Researchers use LEDs as routers
Vibration
speaker:
Vibration
speaker is a kind of speaker unit which is made from vibration principle. It is
also called resonance speaker. Vibration Speakers have no diaphragms and also
called exciters. They drive any solid plane surface they contact and made that surface
sound, so people can have original sound from different materials. Vibration
speakers have a special penetrability which traditional speakers don`t have.
These kind of speakers are mainly used for digital audio speakers, music massage
facilities and music treatment facilities.
Our main vibration speakers include:
1) From
the diameter: we have speakers in diameter of 18mm ~ 44mm.
2) From
the power output, we have speakers of 2W ~ 15W.

WiFi is now an essential part of our lives. We use it for reading, entertainment, work... The magical radio waves carry data constantly between devices and wireless routers. However, the signals of wireless networks are not ubiquitous. Sometimes they are in complex environments, large houses or villa users, and often need to deploy wireless expanders to increase the coverage of wireless signals. Lights are everywhere in the indoor environment. Isn't it better if we can send wireless network signals through the light bulbs? 
Prof. Maite Brandt Pearce from the Department of Electronics and Computer Engineering at the University of Virginia is experimenting with the use of LEDs to send wireless signals. This project is faster than the current standard network connection speed. The researchers named the project “LiFiâ€. The wireless data sent by the LED light bulbs can use no additional energy. Nowadays, more and more lamps have been replaced with LED lights, which can be distributed in different locations in the future. , Connect to a wireless network for internet activity. 
However, Professor Maite Brandt Pearce pointed out that he should not abandon his home wireless router. The LED light bulb emits wireless network signals and cannot replace the WiFi. It is just an auxiliary means to expand the wireless network. In this way, any place in the environment where the light bulb can be installed can become a WiFi access point, and the LiFi connection method is very safe. At present, companies have begun to experiment with the connection of light waves from desk lamps to the Internet according to LiFi technology. 
Sending wireless signals through LED bulbs is just a technology that has a major impact on the Internet of Things. By connecting the wireless network provided by the light bulb, the coffee machine, refrigerator, and water heater at home can all make network connections. In the future, we do not need to extend the wireless network provided by wireless routers to various rooms in the home and let the appliances connect with it. The more convenient LiFi technology really makes us use the wireless network at home without a dead end. It is very worth looking forward to!
