Abstract

An apparatus comprises at least one processor and at least one memory including computer program code the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform: monitoring at least one indicator dependent on a transducer mechanical integration parameter; and determining a change in the at least one indicator.

First claim

The invention claimed is:

1. A method for calibrating an audio transducer mechanical integration of a portable electronic device, comprising:
entering into a mode for calibrating the audio transducer mechanical integration of an audio transducer inside the portable electronic device, wherein the mode for calibrating comprises monitoring at least one indicator associated with the audio transducer mechanical integration while an audio signal is being output by the audio transducer;
determining a change in the monitored at least one indicator, wherein the change is associated with at least one frequency of the audio signal;
determining an audio transducer mechanical integration parameter of the audio transducer mechanical integration based on the change, the audio transducer mechanical integration parameter representing an audio characteristic of the audio transducer inside the portable electronic device; and
calibrating, by the portable electronic device, the audio transducer mechanical integration in response to the determined audio transducer mechanical integration parameter to compensate for the change so as to optimize the audio characteristic of the audio transducer in use.

2. The method according to claim 1 , wherein entering into the mode for calibrating is based on a trigger event, wherein at least one of:
the trigger event is related to at least one of a date and a time;
the trigger event is automatic without requiring any user assistance; and
the trigger event is semi-automatic in response to a user-configured setting.

3. The method according to claim 2 , wherein the user-configured setting is at least one of a date and time set by the user for entering into the mode for calibrating.

4. The method according to claim 1 , wherein entering into the mode for calibrating is based on a trigger event, wherein the trigger event is a manual input from a user.

5. The method according to claim 1 , wherein entering into the mode for calibrating is based on a trigger event, wherein the trigger event includes placing the portable electronic device into a calibration box.

6. The method according to claim 5 , wherein the calibration box includes a frequency identifier module detectable by the portable electronic device, and wherein the trigger event includes detecting the frequency identifier module when the portable electronic device is placed into the calibration box.

7. The method according to claim 1 , wherein the portable electronic device includes a sensor, and wherein entering into the mode for calibrating is based on a trigger event comprising the determination of a received shock by the sensor above a pre-determined threshold.

8. The method according to claim 1 , wherein monitoring the at least one indicator associated with the audio transducer comprises comparing the monitored at least one indicator to a pre-determined threshold.

9. The method according to claim 1 , wherein the audio signal comprises music playing on the portable electronic device.

10. The method according to claim 1 , further comprising determining the change in the at least one indicator is rectifiable, wherein:
determining the audio transducer mechanical integration parameter comprises determining that the audio transducer mechanical integration parameter of the audio transducer mechanical integration is capable of rectifying the change in the at least one indicator; and
calibrating the audio transducer mechanical integration comprises applying the audio transducer mechanical integration parameter to rectify the change.

11. The method as in claim 1 , further comprising displaying an indication to a user of the portable electronic device to place the portable electronic device away from sound interfering surfaces.

12. The method as in claim 1 , wherein the at least one indicator is indicative of a current physical condition of at least one hardware component of the audio transducer mechanical integration inside the device.

13. The method as in claim 12 , wherein the current physical condition of the at least one hardware component is an abnormal physical condition caused by at least one of: a defect, physical damage, and failure of the at least one mechanical component.

14. An apparatus comprising:
at least one processor, and
at least one non-transitory memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, causes the apparatus at least to:
enter into a mode for calibrating an audio transducer mechanical integration of an audio transducer inside the apparatus, wherein the apparatus is a portable electronic device and the mode for calibrating comprises monitoring at least one indicator associated with the audio transducer mechanical integration while an audio signal is being output by the audio transducer;
determine a change in the monitored at least one indicator, wherein the change is associated with at least one frequency of the audio signal;
determine an audio transducer mechanical integration parameter of the audio transducer mechanical integration based on the change, the audio transducer mechanical integration parameter representing an audio characteristic of the audio transducer inside the portable electronic device; and
calibrate, by the portable electronic device, the audio transducer mechanical integration in response to the determined audio transducer mechanical integration parameter to compensate for the change so as to optimize the audio characteristic of the audio transducer in use.

15. The apparatus according to claim 14 , wherein entry into the mode for calibration is based on a trigger event, and wherein at least one of:
the trigger event is related to at least one of a date and a time; and
the trigger event is automatic without requiring any user assistance.

16. The apparatus according to claim 14 , wherein entry into the mode for calibration is based on a trigger event, and wherein the trigger event is semi-automatic in response to a user-configured setting.

17. The apparatus according to claim 16 , wherein the user-configured setting is at least one of a date and time set by the user for entering into the calibration mode.

18. The apparatus according to claim 14 , wherein entry into the mode for calibration is based on a trigger event, and wherein the trigger event is a manual input from a user.

19. The apparatus according to claim 14 , wherein entry into the mode for calibration is based on a trigger event, and wherein the trigger event includes placing the portable electronic device into a calibration box.

20. The apparatus according to claim 19 , wherein the calibration box includes a frequency identifier module detectable by the portable electronic device, and wherein the trigger event comprises detecting the frequency identifier module.

21. The apparatus according to claim 14 , wherein the portable electronic device includes a sensor, and wherein entry into the mode for calibration is based on a trigger event, the trigger event comprising the determination of a received shock by the sensor above a pre-determined threshold.

22. The apparatus according to claim 14 , wherein monitoring the at least one indicator associated with the audio transducer comprises comparing the monitored at least one indicator to a pre-determined threshold.
