Industrial digital barcode reader
A barcode reader assembly for capturing at least one object appearing in a field of view (FOV) is provided that includes a reader enclosure, a circuit board to capture and decode the image, an imaging system, a sound generator housing, and a sound generator. The reader enclosure has an internal cavity in which the circuit board is disposed. The sound generator housing is operably coupled with the circuit board and includes at least one wall having at least one sound port and extending upwardly from the circuit board to form a sound chamber. The sound generator is operably coupled with the circuit board and is at least partially disposed within the sound chamber to generate a sound at a resonant frequency. The sound generator housing is dimensioned to amplify the resonant frequency of the sound generator and port the generated sound to the internal cavity of the reader enclosure.
1. A barcode reader for capturing at least one image of an object appearing in a field of view (FOV), the barcode reader comprising:
a reader enclosure having an internal cavity;
a circuit board disposed within the internal cavity;
an imaging system operably coupled with the circuit board to capture and decode the at least one image of the object appearing in the FOV;
a sound generator housing operably coupled with the circuit board, the sound generator housing including at least one wall extending upwardly from the circuit board to form a sound chamber, the at least one wall including at least one sound port, and
a sound generator operably coupled with the circuit board and being at least partially disposed within the sound chamber, the sound generator configured to generate a sound at a resonant frequency;
wherein the sound generator housing is dimensioned to amplify the resonant frequency of the sound generator and port the generated sound to the internal cavity of the reader enclosure.
2. The barcode reader of claim 1 , wherein the at least one wall contacts a portion of the reader enclosure to define the sound chamber.
3. The barcode reader of claim 1 , wherein the sound generator housing comprises a Helmholtz resonator.
4. The barcode reader of claim 1 , wherein the sound generator comprises a beeper.
5. The barcode reader of claim 1 , wherein at least a portion of the internal cavity of the reader enclosure is sealed from an environment outside of the reader enclosure.
6. The barcode reader of claim 1 , wherein the sound generator housing is at least partially constructed from rubber.
7. A method of assembling a barcode reader for capturing at least one image of an object appearing in a field of view (FOV), the method comprising:
providing a reader enclosure having an internal cavity;
disposing a circuit board within the internal cavity;
disposing an imaging system within the internal cavity and operably coupling the imaging system with the circuit board, the imaging system configured to capture and decode the at least one image of the object appearing in the FOV;
operably coupling a sound generator with the circuit board, the sound generator being configured to generate a sound at a resonant frequency;
operably coupling a sound generator housing with the circuit board, the sound generator housing including at least one wall extending upwardly from the circuit board to form a sound chamber, the at least one wall including at least one sound port;
wherein the sound generator housing is dimensioned to amplify the resonant frequency of the sound generator and port the generated sound to the internal cavity of the reader enclosure.
8. The method of claim 7 , wherein the at least one wall is dimensioned to contact a portion of the reader enclosure to define the sound chamber.
9. The method of claim 7 , wherein the sound generator housing forms a Helmholtz resonator.
10. The method of claim 7 , further comprising sealing at least a portion of the internal cavity of the reader enclosure from an environment outside of the reader enclosure.
11. The method of claim 7 , wherein the sound generator housing is at least partially constructed from rubber.
