Microphone mounting structure of mobile terminal and using method thereof
Disclosed are a microphone mounting structure of a mobile terminal, capable of capturing a sound generated from a subject in an optimum manner while capturing an image and reproducing the captured image, and a using method thereof. In the present invention, a first microphone and a second microphone are arranged on one side surface of a terminal body, in a spaced manner from each other on different axes, so that they can be used in a sound capturing mode. Three or more microphones are arranged on a plurality of surfaces of the terminal body, at various intervals, by interworking with various situation changes. Then, the number of microphones to be used for capturing a sound, and a microphone combination are selected according to a user's behavior scenario. Under such configuration, an optimum audio zooming function can be implemented.
1. A microphone mounting structure of a mobile terminal, comprising:
a first microphone mounted to one side surface of a body, the side surface having a vertical axis extending between a top edge and a bottom edge and a horizontal axis extending between a first side edge and a second side edge; and
a second microphone spaced from the first microphone by a prescribed by a first distance determined by a sampling rate, and
wherein the first microphone and the second microphone are spaced from one another in the horizontal direction by a second distance, and
wherein the first microphone and the second microphone are spaced from one another in the vertical direction by a third distance, the third distance being equal to the second distance.
2. The microphone mounting structure of claim 1 ,
wherein the second distance is 1.45 cm based on a sampling rate of 22.05 KHz.
3. The microphone mounting structure of claim 1 , wherein the first microphone and the second microphone are arranged at a right side or a left side of a camera.
4. The microphone mounting structure of claim 1 , wherein if the first microphone is positioned on the horizontal axis, the second microphone is positioned on the vertical axis, at an upper or lower right side based on the first microphone, at an angle of 45°.
5. The microphone mounting structure of claim 1 , wherein if the first microphone is positioned on the vertical axis based on a user, the second microphone is positioned on the horizontal axis, at an upper or lower left side based on the first microphone, at an angle of 45°.
6. The microphone mounting structure of claim 1 , wherein the first microphone and the second microphone are arranged on different surfaces of the body.
7. The microphone mounting structure of claim 6 , wherein the first microphone is arranged on a rear surface of the body, and the second microphone is arranged on an upper surface or a front surface of the body.
8. The microphone mounting structure of claim 6 , wherein the first microphone is arranged on an upper surface of the body, and the second microphone is arranged on a rear surface or a right side surface of the body.
9. The microphone mounting structure of claim 6 , wherein the first microphone is arranged on a front surface of the body, and the second microphone is arranged on a rear surface of the body.
10. The microphone mounting structure of claim 6 , wherein the first microphone is arranged on a rear surface of the body, and the second microphone is arranged on a right side surface of the body.
11. The microphone mounting structure of claim 6 , wherein the first microphone is arranged on a left side surface of the body, and the second microphone is arranged on a rear surface or an upper surface of the body.
12. The microphone mounting structure of claim 1 , wherein a camera is arranged within a region formed by lines which pass through the first microphone and the second microphone in directions of the horizontal axis and the vertical axis.
13. The microphone mounting structure of claim 12 , wherein an optimum position of the camera is the center of a straight line which connects the first microphone and the second microphone with each other.
