On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

In detail, the front (or top) portion of the front camera module 280, that is, the lens portion is substantially flush with the front portion (or the top face portion) of the body portion 220, And can be tilted at a predetermined angle.

More specifically, when the user wears the wireless acoustic apparatus 200 on the neck, the body part 220 is placed on the collarbone and the breast of the user. In this state, when the front camera module 280 is turned on for photographing, a subject, which the user wants to photograph, may not enter the camera lens. At this time, when the user manually manipulates the front camera module 280 or inputs a tilting command through the photographing application of the mobile terminal 100, the front camera module 280 is tilted forward at a predetermined angle. Hereinafter, an embodiment of the tilting mechanism of the front camera module 280 will be described in detail with reference to the drawings.

8 is an exploded perspective view showing a tilting mechanism of a front camera module included in a wireless audio apparatus according to a third embodiment of the present invention.

Referring to FIG. 8, a tilting structure of the front camera module according to an embodiment of the present invention will be described. In the central portion of the upper housing 221 constituting the body 220, Shaped camera hole 221b is formed. On the rear side of the camera hole 221b, a tilting member 271 is slidably mounted. When the front camera module 280 is in the pre-tilting state, the tilting member 271 covers the rear side of the front camera module 280 to prevent the front camera module 280 from shaking. The front end of the camera hole 221b is rounded to surround the front side of the front camera module 280.

Specifically, the tilting member 271 includes a cover portion 271b that is bent in a "? &Quot; shape to cover a rear portion of the camera hole 221b, and a cover portion 271b that is bent upward from the front end of the cover portion 271b, A grip portion 271a rounded in an arc shape along the side surface of the front camera module 280 and a pressing portion 271d extending forward from the lower end of the cover portion 271b to be bent upward while being inclined upward, And a slide rib 271c protruding from both sides of the cover portion 271b and extending to a predetermined length.

A slide groove 221c extends to a predetermined depth and length at a side edge of the camera hole 221b and the slide rib 271c is inserted into the slide groove 221c. Therefore, when the slide rib 271c is inserted in the slide groove 221c, the tilting member 271 slides in the forward and backward direction as the slide rib 271c moves in the forward and backward directions.

In addition, supporting ends 221e extend downward at both side edges of the camera hole 221b. Guide projections 221d project horizontally on the surfaces of the support ends 221e facing each other. A pair of guide grooves 281 are formed on the left and right side surfaces of the front camera module 280 and the supporting ends 221e are respectively inserted into the guide grooves 281.

In detail, the guide groove 281 extends from the upper surface of the front camera module 280 toward the lower surface thereof, and extends in a curved shape inclined downward toward the front end of the front camera module 280.

Hereinafter, how the front camera module is tilted by the tilting module will be described in detail with reference to the drawings.

FIG. 9 is a longitudinal sectional view taken along line I-I of FIG. 7, and is a sectional view showing a state before the front camera module is tilted.

9, when the front camera module 280 is not tilted, the front surface (or the top surface) of the front camera module 280 is substantially equal to the front surface (or the top surface) of the body portion 220 It forms a plane. That is, the upper housing 221 of the body 220 and the front face (or the upper face) of the front camera module 280 are flush with each other.

The guide protrusion 221d is located at the rear end of the guide groove 281 in a state where the guide protrusion 221d is fitted in the guide groove 281. [ The lower end of the front camera module 280 is seated on the pressing portion 271d of the tilting member 271. The front lower end of the front camera module 280 is in contact with a portion of the pushing portion 271d where the upward inclination of the pushing portion 271d is started. Of course, the slide rib 271c of the tilting member 271 is inserted into the slide groove 221c of the camera hole 221b.

FIG. 10 is a longitudinal sectional view taken along line I-I of FIG. 7, and is a sectional view showing a state in which the front camera module is tilted.

Referring to FIG. 10, when the user holds the grip portion 271a and pushes the tilting member 271 backward, the tilting member 271 slides. Then, the pushing portion 271d retracts and pushes the front lower end portion of the front camera module 280.

The front camera module 280 can not be moved backward by the guide protrusion 221d, but is rotated.

More specifically, when a forward force is applied to the front of the front camera module 280, the guide protrusion 221d moves relative to the guide groove 281. Specifically, since the guide protrusion 221d is in a fixed state, the guide groove 281 moves upward. Here, since the guide groove 281 is rounded in an arc shape, the front camera module 280 rotates counterclockwise on the drawing. The rotation center X of the front camera module 280 is formed on the upper edge of the front end of the front camera module 280.

The upper end of the front end of the front camera module 280 is positioned at the upper end of the upper housing 221 The lower side of the lower side is not lowered. In other words, the front surface of the front camera module 280 does not enter the inside of the body 220. As a result, there is an advantage that the angle of view of the lens of the front camera module 280 is not narrowed.

If the rotation center X of the front camera module 280 is formed at a position away from the front edge of the front camera module 280 toward the center of the front camera module 280, A phenomenon may occur in which the second lens group 221 is photographed together. That is, the angle of view of the camera becomes narrow.

It is noted that the tilting mechanism of the front camera module 280 according to the embodiment of the present invention is not limited to the structure described above. In other words, the idea of the present invention is that the front camera module 280 is capable of tilting forward, and the tilting structure described above is only one example for explaining the concept of the tilting mechanism of the present invention. Therefore, it is once again revealed that various types of tilting mechanisms can be proposed.

In addition, although only the example in which the front camera module 280 is tilted by a manual operation of the user is described above, it is to be understood that the front camera module does not dispense with the event of automatically tilting.

For example, although not shown, a driving motor of the same type as that of the driving motor for rotating the rear camera module 290 is mounted, and a rack / pinion structure is provided, so that the tilting member 271 is moved in the front- A structure capable of sliding movement is also applicable.

As another method of the other tilting mechanism, a hinge axis is horizontally formed on the upper surface edge of the front end of the front camera module 280, and the hinge axis is connected to the rotation axis of the driving motor by the gear assembly The structure is also possible. The hinge axis coincides with a tangent line passing through the upper surface edge of the front end of the front camera module 280 and is rotatably connected to the upper housing 221.

When the front camera module 280 is automatically tilted by the driving motor, the tilting of the front camera module 280 is performed through the mobile terminal 100 communicating with the wireless audio device 200 Can be adjusted.

For example, as mentioned briefly above, a camera photographing application may be installed in the mobile terminal 100, and the tilting command of the front camera module 280 may be inputted by executing the camera photographing application. Then, a command signal for the tilting operation is generated through the control unit of the camera shooting application, and the command signal can be transmitted to the wireless acoustic apparatus 200 through the wireless communication unit. In the wireless acoustic apparatus 200, the front camera module 280 can be tilted at an angle desired by the user by controlling the operation of the driving motor based on the received command signal. Hereinafter, operation control of the camera module using the application will be described with reference to the drawings.

On the other hand, in the photographing waiting state, the angle adjusting icon 34 may be displayed on the lower edge of the display unit 151. [ The angle adjustment icon 34 is a touch button for inputting a command to rotate the front camera module 280 upward or downward. The angle adjustment icon 34 may include an upward rotation button 341 and a downward rotation button 342.

According to this structure, the user can adjust the directing angle of the front camera module 280 while touching the angle adjusting icon 34. [ As the directing angle of the front camera module 280 is changed, the subject displayed on the display unit 151 is also changed, so that the user can adjust the directing angle of the front camera module 280 while checking the subject. Therefore, the user can accurately take a desired subject and confirm it without directly manipulating the body part 220 of the wireless acoustic apparatus 200 by hand.

It is to be noted that the contents described in this drawing apply equally to the rear camera icon 22 and the dual mode icon 23. In particular, when the dual mode icon 23 is selected, the angle adjustment icon for the front camera module and the angle adjustment icon for the rear camera module should be displayed, respectively.

In addition, among the wireless sound devices according to another embodiment described below, all of the wireless sound devices 200 capable of camera tilting can be controlled by the camera running application in the same manner.
