Abstract

Disclosed is a control method for an electronic device. An electronic device according to an embodiment comprises: at least one speaker; and a processor. The processor may be configured to: obtain sound source data; obtain first sound source data, corresponding to a first designated frequency band, from the sound source data by using a filter; generate second sound source data by applying sound effect to at least a portion of sound source data corresponding to a second designated frequency band among the sound source data; generate synthesized sound source data corresponding to the sound source data by synthesizing the first sound source data and the second sound source data; and output the synthesized sound source data through the at least one speaker. Other embodiments may also be possible.

First claim

What is claimed is:

1. An electronic device comprising:
at least one speaker and a processor,
wherein the processor is configured to:
obtain sound source data;
obtain first sound source data corresponding to a first designated frequency band from the sound source data by using a filter;
generate second sound source data by down-sampling the sound source data, wherein the second sound source data corresponds to a second designated frequency band, and wherein a lowest frequency of the second designated frequency band is lower than a lowest frequency of the first designated frequency band;
generate third sound source data by applying a sound effect to the second sound source data generated by down-sampling the sound source data; and
generate synthesized sound source data based on the first sound source data and the third sound source data.

2. The electronic device of claim 1 , wherein the filter comprises a software module.

3. The electronic device of claim 1 , wherein the processor is further configured to determine the first designated frequency band at least based on a designated attribute in response to the sound source data corresponding to the designated attribute.

4. The electronic device of claim 3 , wherein the designated attribute comprises a designated sampling rate, and the processor is further configured to:
identify a frequency band supportable by the sound source data based on the designated sampling rate; and
determine the first designated frequency band based on the supportable frequency band.

5. The electronic device of claim 1 , wherein the processor is further configured to determine the first designated frequency band based on at least some of a user's audible frequency corresponding to the electronic device, a processing capability of the processor, a frequency band supported by the sound effect, a battery state of the electronic device, and a power management state of the electronic device.

6. The electronic device of claim 1 , wherein the processor is further configured to obtain the first sound source data by obtaining the first sound source data based on a high-pass filter module functionally connected with the processor.

7. The electronic device of claim 1 , wherein the processor is further configured to:
identify a first sampling rate of the sound source data; and
generate the second sound source data with a second sampling rate by down-sampling the sound source data.

8. The electronic device of claim 1 , wherein the processor is further configured to correct characteristics corresponding to the first sound source data based on characteristics corresponding to the sound effect applied to the second sound source data.

9. The electronic device of claim 8 , wherein the processor is further configured to correct at least some of time delay characteristics and gain characteristics corresponding to the first sound source data based on at least some of time delay characteristics and gain characteristics corresponding to the sound effect applied to the second sound source data.

10. The electronic device of claim 1 , wherein the processor is further configured to synthesize the first sound source data and the third sound source data in response to energy corresponding to the first sound source data being greater than a preset value.

11. The electronic device of claim 1 , wherein the processor is further configured to select a speaker capable of reproducing the sound source data as a speaker for outputting the synthesized sound source data from among the at least one speaker functionally connected with the processor.

12. The electronic device of claim 1 , wherein the processor is further configured to generate the synthesized sound source data by applying different gain characteristics to the first sound source data and the third sound source data.

13. A method for controlling an electronic device, the method comprising:
obtaining sound source data;
obtaining first sound source data corresponding to a first designated frequency band from the sound source data by using a filter;
generating second sound source data by down-sampling the sound source data, wherein the second sound source data corresponds to a second designated frequency band, and wherein a lowest frequency of the second designated frequency band is lower than a lowest frequency of the first designated frequency band;
generating third sound source data by applying a sound effect to the second sound source data generated by down-sampling the sound source data; and
generating synthesized sound source data based on the first sound source data and the third sound source data.

14. The method of claim 13 , wherein the filter comprises a software module.

15. The method of claim 13 , the method further comprising:
determining the first designated frequency band at least based on a designated attribute in response to the sound source data corresponding to the designated attribute.

16. The method of claim 15 , the method further comprising:
identifying a frequency band supportable by the sound source data based on a designated sampling rate; and
determine the first designated frequency band based on the supportable frequency band;
wherein the designated attribute comprises a designated sampling rate.

17. The method of claim 13 , the method further comprising:
determining the first designated frequency band based on at least some of a user's audible frequency corresponding to the electronic device, a processing capability of a processor of the electronic device, a frequency band supported by the sound effect, a battery state of the electronic device, and a power management state of the electronic device.

18. The method of claim 13 , the method further comprising:
obtaining the first sound source data by using a high-pass filter module functionally connected with a processor of the electronic device.
