The first Bluetooth speaker was developed in the late 1990s by Ericsson in Sweden. Called Bluetooth, it was envisioned as a wireless alternative to RS-232 data cables.

The technology was designed to connect cellular phones, fax machines, laptops, PCs, printers, digital cameras and other devices easily via a secure short-range wireless link.
