In the end of the 40's decade, Telefunken International sent to Brazil, one of their board member called Felix Ewald, with a goal to start a company called Brasifunken which afterwards was named "Telefunken do Brasil".
Few years afterwards Felix Ewald was called back to Germany by Telefunken but he refused to go back to Germany and retired from Telefunken. Together with a group of German friends he started a small factory of loudspeakers called Bravox to supply the radio stations under development at that time.
In 1964 Firmino Rocha de Freitas bought the company's stock from Felix Ewald business partners.
Then Felix Ewald created a Development & Research group, to explore new technologies, since then Bravox has followed its tradition.
