Abstract
An optical code symbol reading system including a housing having a light transmission aperture, and at least one sound port formed in the housing. The system includes an optical code symbol reading subsystem for optically reading a code symbol in the field external to the light transmission aperture, and generating symbol character data representative of the read code symbol. An electro-acoustic transducer is disposed in the housing for producing sonic energy. Also, an acoustic-waveguide structure is disposed in the housing, for coupling the sonic energy produced from the electro-acoustic transducer, to the at least sound wave port formed the housing, to audibly signal the reading of a code symbol to the operator of the optical code symbol reading system.
