Abstract

An audio speaker contains a tweeter capable of continuous rotation, where the audio speaker contains the tweeter and an axis mount assembly. The tweeter is removably connected to the axis mount assembly. The audio speaker also contains a first connection member capable of maintaining electrical communication with the axis mount assembly throughout continuous rotation of the axis mount assembly. The axis mount assembly contains a terminal plate connected to a bottom portion of the tweeter, where the terminal plate maintains electrical communication with the tweeter. The axis mount assembly also contains an axis mount faceplate capable of receiving the terminal plate and tweeter within an indented portion of a top portion of the axis mount faceplate. The axis mount assembly further contains an axis mount spacer and a second connection member that maintains electrical communication with the first connection member throughout continuous rotation of the axis mount assembly.

a first connection wire in electrical communication with said second connection terminal; and

a second connection wire, in electrical communication with said first connection terminal, wherein said first connection wire and said second connection wire electrically communicate with said second connection member.

7. The audio speaker of claim 2 , wherein a plane of said top portion of said axis mount faceplate is not perpendicular to a central axis of said audio speaker.

8. An audio speaker, comprising:

a frame;

a tweeter having a top portion and a bottom portion;

an axis mount assembly, wherein said tweeter is removably connected to said axis mount assembly;

a first connection member, capable of maintaining electrical communication with said axis mount assembly throughout continuous rotation of said axis mount assembly within said audio speaker;

a terminal plate capable of connecting to said bottom portion of said tweeter, wherein said terminal plate maintains electrical communication with said tweeter;

an axis mount face plate having a top portion and a bottom portion, wherein said axis mount face plate is capable of receiving said terminal plate and tweeter within an indented portion of said top portion of said axis mount face plate;
