Abstract

Disclosed are a device and a method for outputting a sound wave for content synchronization between devices and operation control of an external device, and the external device. The device for outputting a sound wave according to one embodiment of the present invention includes: a storage unit configured to store content data of content; a playing unit configured to play the content data; and an output unit configured to output a sound wave as a result of the playing of the content data, wherein the sound wave allows an external device to initiate an operation associated with the content.

Claims

1. A device for outputting a sound wave, comprising:

a storage unit configured to store content data of content;

a control information generation unit configured to generate control information including synchronization information or time information corresponding to the content, wherein the control information generation unit generates first control information and second control information; and

a sound wave data generation unit configured to generate first sound wave data corresponding to the first control information and second sound wave data corresponding to the second control information,

a playing unit configured to play the first sound wave data, the second sound wave data, and the content data, and

an output unit configured to output a first sound wave and a second sound wave as a result of playing the first sound wave data, the second sound wave data, and the content data,

wherein the output unit comprises a speaker,

wherein the first sound wave causes a first external device to initiate a first operation associated with the content, and the second sound wave causes a second external device to initiate a second operation associated with the content, and

wherein the first external device and the second external device each further comprise a microphone configured to receive the first sound wave and the second sound wave;

wherein the first operation is different from the second operation, and;

wherein the first operation corresponding to the first sound wave data and the second operation corresponding to the second wave data are synchronized with the playing of the content data, based on tempo, play bar, and play starting time of the content data;

wherein the first sound wave is within a range of 100 Hz to 16000 Hz, wherein the second sound wave is within a range of 16000 Hz to 24000 Hz.

2. The device of claim 1, wherein the output unit outputs the first sound wave corresponding to the content data played through a sound wave output device, and outputs the second sound wave corresponding to the sound wave data played through the sound wave output device.

3. The device of claim 1, wherein the device is a mobile device and the content is a music content.

4. The device of claim 1, further comprising:

a display unit configured to display an image or a text on the display of the device as a result of the playing of the content data.

5. The device of claim 1, wherein the first operation displays a first image on a display of the first external device and wherein the second operation displays a second image on a display of the second external device, wherein the first image is different from the second image.
