Whether you want to share an educational video or listen to music, induction technology in this speaker instantly amplifies music from most tablets or smartphones for crystal clear audio in the gym or classroom. Induction technology converts analog sound waves from a media device into an electrical signal, amplifies that signal, and projects it through a speaker with increased volume.
This allows teachers to fill the classroom with sound from a smartphone or tablet without wires, Wi-Fi, Bluetooth, or setup of any kind. Simply place the device on the dock for crystal clear audio and easily switch devices in a flash. Includes a rechargeable lithium ion battery. Audio-in port allows teachers to amplify other devices as well. 4”H x 10”W x 4”D; 1 lb.
