Abstract

An audio electronic device includes a player, an output device, a detector, and an automatic turn-off module. The player is for reproducing audio data. The output device is for transforming the audio data to audible sound. The detector is for detecting positional shift of the output device. The automatic turn-off module is for turning off the player based on the positional shift. An automatic turn-off method is also disclosed.

Claims

a player for reproducing audio data;

an output device for transforming the audio data to audible sound;

a detector for detecting a positional shift of the output device; and

an automatic turn-off module for turning off the player based on the positional shift.

2. The audio electronic device according to claim 1, wherein the detector is for generating a detected signal corresponding to the positional shift, and the automatic turn-off module comprises a processor for generating displacement detected data from the detected signal.

3. The audio electronic device according to claim 2, wherein the automatic turn-off module comprises a memory for storing start time, a motion monitoring time length, wait time, a displacement value, and the displacement detected data.

4. The audio electronic device according to claim 3, wherein the automatic turn-off module comprises an interface for allowing the start time, the motion monitoring time length, the wait time, the displacement value to be set and modified.

5. The audio electronic device according to claim 3, wherein the automatic turn-off module comprises a controller for calculating a current displacement detected data from the stored displacement detected data, and comparing the current detected with the displacement value.

generating displacement detected data from the detected signal;

judging whether one motion monitoring time length has passed;

calculating current displacement detected data if the motion monitoring time length has passed;

comparing the current displacement detected data with a displacement value;

prompting for a user input within wait time if the current displacement detected data is not greater than the displacement value;

turning off a player if the user input is not provided.

10. The automatic turn-off method according to claim 9, further comprising:

setting start time, the motion monitoring time length, the wait time, the displacement value into a store module;

measuring the time;

judging whether the time reaches the start time;

enabling a detector if the time reaches the start time.

11. The automatic turn-off method according to claim 10, further comprising:

going to step measuring the time if the time does not reach the start time.

12. The automatic turn-off method according to claim 9, further comprising:

storing the displacement detected data.

13. The automatic turn-off method according to claim 9, further comprising:

going to step detecting a positional shift and generating a motion detected signal if the motion monitoring time length has not passed.
