Abstract
A hearing instrument includes a faceplate and a shell. The faceplate is a round plate that has a moat defined in the surface of the plate and at least one feature associated with the plate for joining with a hearing instrument component. The moat is a trench or channel that is defined in the surface of the faceplate and includes a wall structure for coupling with a shell of a hearing instrument. The moat may be defined symmetrically about the at least one feature. The moat may be oval in shape and have a rectangular cross-section. A cut out is positioned on the faceplate for use in speeding the excising of material from the faceplate once the shell has been coupled to the faceplate.
