Abstract

A calibration device and method of manufacturing the same. The calibration device for a hearing earpiece configured to at least partially protrude into the ear canal of a user includes a calibration base. The calibration base a calibration insert. An air chamber is defined between the calibration base and the calibration insert. The calibration device also includes at least one earpiece receiving mechanism defined on the calibration insert. The at least one earpiece receiving mechanism is configured to create an sealed connection between given ear piece and the air chamber for calibration. The earpiece receiving mechanism is configured to at least partially receive the given earpiece. A corresponding method of manufacturing is also included.

Claims (22)

1. A calibration device for a hearing earpiece configured to at least partially protrude into an ear canal of a user, the calibration device comprising:

a calibration base comprising a calibration insert, wherein an air chamber is defined between the calibration base and the calibration insert; and,

at least one earpiece receiving mechanism defined on the calibration insert, the at least one earpiece receiving mechanism configured to create a sealed connection between a given earpiece and the air chamber for calibration, wherein the at least one earpiece receiving mechanism is configured to at least partially receive the given earpiece, wherein the at least one earpiece receiving mechanism comprises a tensioning component, wherein the tensioning component is spring loaded and is configured to hold the given earpiece in the at least one earpiece receiving mechanism during calibration.

2. The calibration device of claim 1 , further comprising a calibration tubing receiver configured to operably couple the air chamber with a calibrator system, wherein the calibrator system provides calibration to the given earpiece held in the at least one earpiece receiving mechanism.

3. The calibration device of claim 1 , wherein the at least one earpiece receiving mechanism comprises one or more microphone seals configured to engage with the given earpiece such that an airtight seal is achieved between the microphone seal and the given earpiece microphone.

4. The calibration device of claim 1 further comprising an ejector mechanism, wherein the ejector mechanism is configured to allow the removal of the given earpiece from the calibration device.

5. The calibration device of claim 1 , wherein the at least one earpiece receiving mechanism comprises a stationary block and a tensioning component such that the given earpiece is held in place during operation between the stationary block and the tensioning component.

6. The calibration device of claim 5 , wherein the stationary block comprises a microphone seal, wherein the microphone seal is configured to seal one of the microphones of the given earpiece in an instance the given earpiece is positioned between the stationary block and the tensioning component.

7. The calibration device of claim 6 , wherein an interior microphone seal is positioned on calibration device between the stationary block and the tensioning component, wherein the interior microphone is configured to seal another microphone of the given earpiece in an instance in which the given earpiece is positioned between the stationary block and the tensioning component.

8. The calibration device of claim 1 further comprising a calibration tubing configured to be removably attached to a tubing receiver at a first end and a calibrator system at a second end opposite the first end.

9. The calibration device of claim 8 further comprising a lid, wherein the lid is configured to be removably coupled to the calibration base at a locking end of the calibration base and operably coupled to the calibration base at a connection end opposite the locking end, wherein the lid is configured to move between an opened position and a closed position.

10. A method of manufacturing a calibration device for a hearing earpiece configured to at least partially protrude into an ear canal of a user, the method comprising:

providing a calibration base comprising a calibration insert, wherein an air chamber is defined between the calibration base and the calibration insert; and

providing at least one earpiece receiving mechanism defined on the calibration insert, the at least one earpiece receiving mechanism configured to create a sealed connection between a given earpiece and the air chamber for calibration, wherein the at least one earpiece receiving mechanism is configured to at least partially receive the given earpiece, wherein the at least one earpiece receiving mechanism comprises a tensioning component, wherein the tensioning component is spring loaded and is configured to hold the given earpiece in the at least one earpiece receiving mechanism during calibration.

11. The method of claim 10 , further comprising providing a calibration tubing receiver configured to operably couple the air chamber with a calibrator system, wherein the calibrator system provides calibration to the given earpiece held in the at least one earpiece receiving mechanism.

12. The method of claim 10 , wherein the at least one earpiece receiving mechanism comprises one or more microphone seals configured to engage with the given earpiece such that an airtight seal is achieved between the microphone seal and the given earpiece microphone.

13. The method of claim 10 further comprising providing an ejector mechanism, wherein the ejector mechanism is configured to allow the removal of the given earpiece from the calibration device.

14. The method of claim 10 , wherein the at least one earpiece receiving mechanism comprises a stationary block and a tensioning component such that the given earpiece is held in place during operation between the stationary block and the tensioning component.

15. The method of claim 14 , wherein the stationary block comprises a microphone seal, wherein the microphone seal is configured to seal one of the microphones of the given earpiece in an instance the given earpiece is positioned between the stationary block and the tensioning component.

16. The method of claim 15 , wherein an interior microphone seal is positioned on calibration device between the stationary block and the tensioning component, wherein the interior microphone is configured to seal another microphone of the given earpiece in an instance in which the given earpiece is positioned between the stationary block and the tensioning component.

17. The method of claim 10 further comprising providing a calibration tubing configured to be removably attached to a tubing receiver at a first end and a calibrator system at a second end opposite the first end.

18. The method of claim 17 further comprising operably coupling a lid to the calibration base, wherein the lid is configured to be removably coupled to the calibration base at a locking end of the calibration base and operably coupled to the calibration base at a connection end opposite the locking end, wherein the lid is configured to move between an opened position and a closed position.
