Optical code symbol reading system employing an acoustic-waveguide structure for coupling sonic energy, produced from an electro-transducer, to sound wave ports formed in the system housing
First Claim
1. An optical code symbol reading system comprising:
- a housing having a light transmission aperture, and at least one sound port formed in said housing;
an optical code symbol reading subsystem for optically reading a code symbol in a field external to said light transmission aperture, and generating symbol character data representative of the read code symbol;
an electro-acoustic transducer disposed in said housing, for producing sonic energy; and
an acoustic-waveguide structure disposed in said housing, for coupling the sonic energy produced from said electro-acoustic transducer, to said at least one sound wave port formed said housing, to audibly signal the reading of a code symbol to the operator of said optical code symbol reading system.

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.
