Device and method for outputting sound wave, and mobile device and method for generating control information corresponding to the sound wave

A method for controlling a device, comprising:

• receiving a sound wave output from a mobile device through a sound wave reception device;
• acquiring control information associated with operation of the device from the received sound wave;
• and
• performing the operation based on the control information,
• wherein the acquiring of the control information comprises:
• determining a frequency band, to which at least one frequency identified from a certain frame within the received sound wave corresponds, from an audible sound wave frequency band and a non-audible sound wave frequency band, and partial information based on the frequency band and the at least one identified frequency;
• and
• acquiring control information corresponding to the received sound wave based on each of the determined partial information.

A mobile device, comprising:

• a sound wave reception unit that receives a sound wave output from a device, through a sound wave reception device;
• a status information acquisition unit that acquires status information of the device by using the sound wave;
• a control information generation unit that generates control information for the device based on the status information;
• a sound wave data generation unit that generates sound wave data corresponding to the control information;
• and
• an output unit that outputs a sound wave corresponding to the generated sound wave data through a sound wave output device,
• wherein the sound wave data generation unit
• generates a plurality of partial information corresponding to the control information,
• determines a frequency band, which corresponds to each of the plurality of the partial information, from an audible sound wave frequency band and a non-audible sound wave frequency band,
• determines at least one frequency corresponding to each of the plurality of the partial information within the determined frequency band,
• generates a sound signal corresponding to the determined frequency for each of the plurality of the partial information, and
• generates the sound wave data by combining the sound signals with one another.
