Abstract

A speaker is provided. The speaker may include: a sensor adapted to sensing object movement within its sensing range; and a processing device configured to generate a volume control instruction if the sensor senses one of the following movements of an object: movement away from the first sensor, and movement towards the first sensor. More intuitive and easy-to-understand ways to control playback of the media player may be achieved.

Claims

1. A speaker, comprising:

a sensor adapted to sensing object movement within its sensing range; and

a processing device configured to generate a volume control instruction if the sensor senses one of the following movements of an object;

movement away from the sensor, and movement towards the sensor.

2. The speaker according to claim 1, wherein the processing device is configured to:

generate a first volume control instruction to increase volume if the sensor senses the object'"'"'s movement away from the sensor; and

generate a second volume control instruction to decrease volume if the sensor senses the object'"'"'s movement towards the sensor.

3. The speaker according to claim 1, wherein the processing device is further configured to:

generate the volume control instruction to change volume to an extent based on a distance the object moves which is sensed by the sensor.

4. The speaker according to claim 1, wherein the processing device is further configured to:

determine whether the sensor senses the object staying still for at least a predetermined period of time before sensing the movement away from the sensor of the object or the movement towards the sensor of the object; and

if yes, generate the volume control instruction based on the movement away from the sensor of the object or the movement towards the sensor of the object.

5. The speaker according to claim 4, wherein the processing device is further configured to:

if the sensor senses the object staying still for at least the predetermined period of time, control the speaker to give an audible or visible notice for reminding a user to move the object.

6. A speaker, comprising:

a sensor adapted to sensing a distance between the sensor and an object in a sensing range of the sensor; and

a processing device configured to generate a volume control instruction based on the distance sensed by the sensor.

7. The speaker according to claim 6, wherein the processing device is configured to:

generate a first volume control instruction to increase volume if the distance sensed by the sensor increases; and

generate a second volume control instruction to decrease volume if the distance sensed by the sensor decreases.

8. The speaker according to claim 6, wherein the processing device is further configured to:

if the distance sensed by the sensor changes, generate the volume control instruction to change volume to an extent based on how much the distance changes.

9. The speaker according to claim 6, wherein the processing device is further configured to:

determine whether the distance sensed by the sensor remains still for at least a predetermined period of time before the distance changes; and

if yes, generate the volume control instruction based on a change of the distance.

10. The speaker according to claim 9, wherein the processing device is further configured to:

if the distance sensed by the sensor remains for at least the predetermined period of time, control the speaker to give an audible or visible notice for reminding a user to change the distance.

11. The speaker according to claim 6, further comprising a gesture control device for controlling an audio system, wherein

the sensor is further adapted for sensing object movement within its sensing range;

and

the processing device is further configured to generate a corresponding volume control instruction to control the volume of the audio system if the sensor senses one of the following movements of an object;

movement away from the sensor, and movement towards the sensor.

12. The speaker according to claim 11, wherein the processing device is further configured to:

generate a first volume control instruction to increase volume if the sensor senses the object'"'"'s movement away from the sensor; and

generate a second volume control instruction to decrease volume if the sensor senses the object'"'"'s movement towards the sensor.

13. The speaker according to claim 11, wherein the processing device is further configured to:

generate the corresponding volume control instruction to change volume of the audio system to an extent based on a distance the object moves which is sensed by the sensor.

14. The speaker according to claim 11, wherein the processing device is further configured to:

determine whether the sensor senses the object staying still for at least a predetermined period of time before sensing the movement away from the sensor of the object or the movement towards the sensor of the object; and

if yes, generate the corresponding volume control instruction based on the movement away from the sensor of the object or the movement towards the sensor of the object.

15. The speaker according to claim 14, wherein the processing device is further configured to:

if the sensor senses the object staying still for at least the predetermined period of time, control the gesture control device to give an audible or visible notice for reminding a user to move the object.

16. A method for controlling an audio system based on gesture, comprising:

a control device sensing movements of an object in its sensing range; and

generating a corresponding volume control instruction to control the volume of the audio system if one of the following movements of an object is sensed;

movement away from the control device, and movement towards the control device.

17. The method according to claim 16, wherein the control device generates a first volume control instruction to increase the volume of the audio system if the object'"'"'s movement away from the control device is sensed;

and generates a second volume control instruction to decrease the volume of the audio system if the object'"'"'s movement towards the control device is sensed.

18. The method according to claim 16, wherein the control device generates the volume control instruction to change the volume of the audio system to an extent based on a distance the object moves which is sensed by the control device.

19. The method according to claim 16, further comprising:

the control device determining whether the object stays still for at least a predetermined period of time before the movement away from the control device of the object or the movement towards the control device of the object is sensed; and
