Description
Various embodiments of the present invention relate to an electronic apparatus and a volume control method thereof capable of appropriately controlling the volume according to the magnitude of ambient sound (e.g., noise).
Recently, the spread and use of electronic devices (for example, mobile communication terminals) is rapidly increasing owing to the remarkable development of information communication technology and semiconductor technology. Accordingly, the electronic device has become a necessity for modern people and provides various functions required by users. For example, the mobile communication terminal provides various functions such as a call function, an image or moving picture shooting function, a broadcast receiving function, an Internet access function, a recording function, and the like.
On the other hand, recent electronic devices provide a sound output function. For example, it provides multimedia playback functions such as music and video. The electronic device provides a volume control function for controlling the volume level during multimedia reproduction.
However, the electronic device can increase or decrease the volume by a predetermined amount through a volume key or a touch input (for example, a touch of a volume control menu). However, the user of the electronic device must appropriately change the volume according to the surrounding environment. For example, if the surroundings are noisy, the user should increase the volume. Conversely, if the surroundings are quiet, the user may have to reduce the volume. As described above, there is an inconvenience that the user has to control the volume according to the surrounding situation.
In addition, the electronic device must increase or decrease the volume by a predetermined magnitude. As a result, if the surroundings are noisy, the user may not feel the difference due to one or two volume increases, and may have to increase the volume a number of times. At this time, the user may want to feel the difference even when the volume is increased by one time. However, since the volume sensitivity of the electronic device is determined, it is necessary to increase the volume several times.
Conversely, if the surroundings are quiet, the user may feel that one volume increase or decrease has a large difference. At this time, the user may want to set the volume to an intermediate value. However, since the volume sensitivity of the electronic device is determined regardless of the surrounding situation, the volume can not be set to an intermediate value.
Accordingly, various embodiments of the present invention can provide an electronic apparatus for detecting an external sound, and adjusting a maximum volume value and a volume sensitivity according to the size of the detected external sound, and a method of controlling the volume thereof.
An electronic apparatus according to an embodiment of the present invention includes an audio processing unit for collecting external sound through a sound collecting apparatus and outputting an audio signal at a set volume level; And changing the maximum volume value according to the level of the collected external sound, changing the volume sensitivity corresponding to the changed maximum volume value, and outputting the audio signal based on the changed maximum volume value and the changed volume sensitivity. And a control unit for controlling the audio processing unit.
A volume control method of an electronic apparatus according to an embodiment of the present invention includes: an operation of collecting external sound through a sound collection apparatus; Changing a maximum volume value according to the level of the collected external sound and changing volume sensitivity corresponding to the changed maximum volume value; And outputting an audio signal based on the changed maximum volume value and the changed volume sensitivity.
A computer-readable recording medium according to an embodiment of the present invention includes an operation of collecting external sound through a sound collection device; Changing a maximum volume value according to the level of the collected external sound and changing volume sensitivity corresponding to the changed maximum volume value; And outputting an audio signal based on the changed maximum volume value and the changed volume sensitivity.
Various embodiments of the present invention can adjust the maximum volume value and volume sensitivity according to the magnitude of the external sound (ambient noise). For example, various embodiments of the present invention can reduce the maximum volume value and increase the volume sensitivity in a quiet environment. Conversely, various embodiments of the present invention can increase the maximum volume value and reduce the volume sensitivity when the surroundings are noisy. As such, various embodiments of the present invention can provide smart volume control.
