Abstract

A portable electronic device (100) comprises an attached device (190,195), a vibrator (175), and a processor (105) coupled between the attached device (190, 195) and the vibrator (175). The processor (105) is adapted to detect the attached device (190, 195), determine an identification for the attached device (190,195), associate a drive voltage with the identification, and drive the vibrator (175) using the drive voltage.

Claims

1. A method of operation of a portable electronic device comprising the steps of:

associating each of a plurality of drive voltages with at least one device identification;

detecting an attached device;

determining an identification for the attached device;

selecting a drive voltage from the plurality of drive voltages; and

driving a vibrator using the drive voltage.

2. A method of operation as recited in claim 1, wherein the detecting step comprises detecting an attached battery.

3. A method of operation as recited in claim 1, wherein the detecting step comprises detecting an attached accessory.

4. A method of operation as recited in claim 1, wherein the determining step comprises the step of:

receiving the identification from the attached device.

5. A method of operation as recited in claim 1, wherein the determining step comprises the step of:

querying the attached device to obtain the identification.

6. A method of operation as recited in claim 1, wherein the associating step comprises the step of:

retrieving the drive voltage from a memory in which the identification and the drive voltage are stored.

7. A method of operation of a portable electronic device as recited in claim 1 wherein the associating step comprises the step of:

calculating the drive voltage from the identification.

8. A portable electronic device comprising:

an attached device;

a vibrator;

a memory that includes a plurality of drive voltage values that are each associated with at least one device identification and

a processor coupled between the attached device and the vibrator, the processor adapted to;

detect the attached device,

select a drive voltage from the plurality of drive voltage values, and

drive the vibrator using the drive voltage.

9. A portable electronic device as recited in claim 8 wherein the attached device comprises an attached battery.

10. A portable electronic device as recited in claim 8, wherein the attached device comprises an attached accessory.

11. A portable electronic device as recited in claim 8, further comprising:

a power management block coupled between the processor and the vibrator for creating the drive voltage for the vibrator in response to a command from the processor.

12. A portable electronic device as recited in claim 8, further comprising a memory coupled to the processor for storing a plurality of identifications and associated drive voltages, wherein the processor is adapted to retrieve the drive voltage associated with the identification.
