Abstract:
In the invention a speaker apparatus acoustically combines the earpiece and hands free functions. Thus a speaker has acoustically separated functions for acting as the earpiece and as the hands free. The speaker apparatus has a back cavity having an outlet so that the damped sound of the outlet operates as the earpiece. The front of the speaker apparatus operates as the louder hands free.
