Abstract

An electronic device is provided. The electronic device includes a first housing, a second housing coupled to the first housing, a speaker disposed in the first housing and outputs an audio signal, a flexible display disposed in the first and second housings, and in which a size of a visual area can be expanded according to the movement of the second housing, a first duct line formed in the first housing, a second duct line formed at a position corresponding to the first duct line, and is formed in the second, a third duct line connected to the first duct line, and is formed in the second housing, and a processor, operatively connected to the speaker and the flexible display, configured to sense the moved distance of the second housing with respect to the first housing, and correct the characteristics of the audio signal based on the sensed moved distance.

First claim

What is claimed is:

1 . An electronic device comprising:
a first housing and a second housing coupled to the first housing to be movable with respect to the first housing; a speaker disposed in the first housing to output an audio signal; and a flexible display disposed in the first housing and the second housing and of which a size of an area visually exposed via a front surface of the electronic device is changeable according to a movement distance of the second housing with respect to the first housing; at least one processor; and memory storing at least one computer program including computer-executable instructions, and wherein a first passage is formed in the first housing to allow the audio signal to be output to outside of the first housing, wherein a second passage and a third passage are formed in the second housing, wherein in a state where the movement distance of the second housing is in a first range, the second passage is positioned at a position corresponding to the first passage to allow the audio signal passed through the first passage to be output to the outside of the electronic device, wherein in a state where the movement distance of the second housing is in a second range, the third passage is positioned at a position corresponding to the first passage to allow the audio signal passed through the first passage to be output to the outside of the electronic device, and wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
detect the movement distance of the second housing with respect to the first housing, and
change characteristics of the audio signal to be produced from the speaker based on the movement distance of the second housing.

2 . The electronic device of claim 1 , wherein, in a state where the movement distance of the second first housing is in a third range, the audio signal is output to the outside of the electronic device.

3 . The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, further cause the electronic device to:
apply a first correction filter in case that the movement distance is in the first range, and apply a second correction filter in case that the movement distance is in the second range.

4 . The electronic device of claim 3 , wherein the instructions, when executed by the at least one processor individually or collectively, further cause the electronic device to apply a median value of the characteristics of the first correction filter and the characteristics of the second correction filter, while the movement distance changes from the first range to the second range.

5 . The electronic device of claim 3 , wherein the instructions, when executed by the at least one processor individually or collectively, further cause the electronic device to apply a third correction filter in case that the movement distance is in a third range.

6 . The electronic device of claim 5 , wherein the instructions, when executed by the at least one processor individually or collectively, further cause the electronic device to differently apply the third correction filter according to a volume size of the audio signal produced from the speaker.

7 . The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to, in correcting the characteristics of the audio signal:
in case of obtaining an input which turns on a configuration to correct audio output, perform correction of the characteristics of the audio signal, and in case of obtaining an input which turns off the configuration to correct audio output, not perform correction of the characteristics of the audio signal.

8 . The electronic device of claim 1 , further comprising:
a display movement detection sensor, wherein the instructions, when executed by the at least one processor individually or collectively, further cause the electronic device to detect the movement distance of the second housing with respect to the first housing using the display movement detection sensor.

9 . The electronic device of claim 1 , wherein the first passage, the second passage, and the third passage have a shape of multiple holes.

10 . The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to, in correcting the characteristics of the audio signal, tune the audio signal, adjust volume of the audio signal, and adjust amplification of the audio signal.

11 . The electronic device of claim 10 , wherein the instructions, when executed by the at least one processor individually or collectively, further cause the electronic device to adjust amplitude of the audio signal for each frequency band section.

12 . The electronic device of claim 1 , wherein the second housing comprises:
an inner housing and an outer housing; fixing protrusions configured to fix the flexible display and arranged on the outer housing; and fixing holes configured to seat the fixing protrusions thereinto and formed through the inner housing.

13 . The electronic device of claim 1 ,
wherein the memory is configured to store the characteristics of the audio signal corresponding to the movement distance, and wherein the instructions, when executed by the at least one processor individually or collectively, further cause the electronic device to correct the characteristics of the audio signal produced from the speaker based on the characteristics of the audio signal stored in the memory.

14 . The electronic device of claim 13 , wherein the instructions, when being executed by the at least one processor individually or collectively, causes the electronic device to identify a correction filter based on the characteristics of the audio signal stored in the memory.

15 . The electronic device of claim 14 ,
wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
apply a first correction filter in case that the movement distance is in the first range, and
apply a second correction filter in case that the movement distance is in the second range, and
wherein the first correction filter and the second correction filter are configured based on a case where the movement distance is in a third range.

16 . An electronic device comprising:
a first housing and a second housing coupled to the first housing to be movable with respect to the first housing; a speaker included in the first housing and being output an audio signal; a flexible display disposed in the first housing and the second housing and movable according to the second housing; at least one processor; and memory storing at least one computer program including computer-executable instructions, and wherein a first pipe passage is formed in the first housing to allow the audio signal to be output to the outside of the first housing, wherein a second pipe passage is formed in the second housing, wherein in a state where a movement distance of the flexible display with respect to the first housing is in a first range, the second pipe passage is positioned at a position corresponding to the first pipe passage to allow the audio signal to be output to the outside of the electronic device, wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
