## Background
CLAIM OF PRIORITY
This application claims the benefit under 35 U.S.C. §119(a) of Korean patent application filed on Aug. 26, 2014 in the Korean Intellectual Property Office and assigned Serial number 10-2014-0111832, the entire disclosure of which is hereby incorporated by reference.
TECHNICAL FIELD
The present disclosure relate to a rotary device and an electronic device including the same, and more particularly, to a rotary device capable of being detachably attached to a device, such as eyeglasses, by a user who uses eyeglasses.
BACKGROUND
Due to the advancement of electronic techniques, various wearable devices are being developed. The wearable devices are worn on a user's body to be capable of providing various functions to the user. For example, there is an increasing developing effort to implement, for example, a game, music, multimedia contents, or an application that is usable in an existing electronic device, in a wearable device. Further, in consideration of the fact that the wearable device is used in a state where it is positioned close to the user's body, research and development to mount various sensors on a wearable device are actively on the way.
A conventional headset requires a separate device in order to fix it to a user's body. The separate device is used in a state where it is put on, for example, the user's head or neck, which may cause the user to feel inconvenience.
In addition, when the headset is not used, the headset is carried in a state where it is completely separated from the user's body. However, since the device to fix the headset to the user's head or neck has a large volume, there is a problem in that the portability is poor.
In order to solve this problem, for example, an earphone or earpiece or earbud or the like that typically rest on or within a user's inner ears, and have a relatively smaller size than headsets that typically rest on or over the user's outer ears, may be used instead of headsets. Although earphones have become increasingly smaller in size, when the earphones are not in use, there is still a problem of portability because there is no convenient place to store the earphones when not in use. In particular, when in the ear, the earphones are easily carried, but when not in use, the earphones are separated from the user's body and must be held or separately carried. Thus, both earphones and headsets present problems to the user in terms of their being portable. As used herein, the term headset or earphone or the like may be used interchangeably and may generally refer to any of the following: headsets, headphones, earphones, and the like.
SUMMARY
The present disclosure relates to improving the usability and portability of an electronic device (e.g., a Bluetooth headset, a heart rate monitor, or other sensors) including a sound module or various sensors, and to allow a user using, for example, eyeglasses, to conveniently use the electronic device detachably attached to a part of the user's body.
In accordance with an aspect of the present disclosure, a rotary device is provided. The rotary device may include: a binding unit configured to be detachably attached to a part of an external object and including a side surface; a stationary unit positioned adjacent to the side surface of the binding unit. The stationary unit may be formed integrally with or coupled to the binding unit. A rotary unit may be coupled to the stationary unit to be at least partially rotatable with respect to the stationary unit. The rotary unit may be rotatable between a first position where the rotary unit forms a first angle with respect to a longitudinal axis extending through a part of the external object and a second position where the rotary unit forms a second angle with respect to the longitudinal axis extending through the part of the external object, at the first position. In the first position, the rotary unit may be a first distance from a geometric plane including the side surface, and at the second position, the rotary unit be a second distance from the plane including the side surface. The second distance being different from the first distance.
In accordance with another aspect of the present disclosure, an electronic device comprising a rotary device is provided. The rotary device may include: a binding unit configured to be coupled to an external object. A stationary unit may be coupled to the binding unit, a rotary unit may be coupled to the stationary unit. The rotary may be configured to be fixed among a plurality of set positions. For example, as the rotary unit is rotated with respect to the stationary unit, the rotary unit is sequentially moved toward or away from the binding unit at the plurality of positions. The rotary device may include a main body coupled to the rotary unit, and the main body includes a coupling part coupled to the rotary unit, and a first module or a second module mounted thereon.
These and other features of the present disclosure will be more fully described hereinbelow with reference to the accompanying figures.

FIG. 3 is a view for describing a use state of a rotary device 1 according to various embodiments according to the present disclosure.
According to various embodiments according to the present disclosure, a rotary device 1 is capable of being detachably attached to an external object 2 such as a temple of an eyeglass frame. The rotary device 1 may include a binding unit 10, a stationary unit 20, and/or a main body 30.
The binding unit 10 may be capable of being detachably attached to a part of the external object 2, and may include a side surface 11.
The stationary unit 20 is positioned adjacent to the side surface 11 of the binding unit 10 and may be formed integrally with or connected to the binding unit 10.
The main body 30 may be connected to the stationary unit 20 to be at least partially rotatable.
The rotary device 1 may be rotated between a plurality of set positions in a state where it is coupled to the external object 2. FIG. 3 illustrates that the main body 30 is rotated about one axis. At the plurality of positions, the free rotation of the main body 30 is restricted to be fixed in position, and the main body 30 is capable of being rotated only when a predetermined external force is applied thereto.
The main body 30 may be rotatable between a first position where the main body 30 forms a first angle with a portion of the external object 2 and a second position where the main body 30 forms a second angle with the portion of the external object 2.
At the first position, the main body 30 may have a first distance with respect to a plane including to the side surface 11. At the second position, the main body 30 may have a second distance with respect to the plane including the side surface 11. The second distance may be different from the first distance.
According to one embodiment, the rotary device 1 may further include an additional module formed as a separate component that is fixed to or connected to the main body 30. The main body 30 may include an electronic part of the additional module. The additional module may be, for example, a sound module, a Heart Rate Monitor (HRM), or any of various other sensors. The sound module may be an earphone or a bone conduction speaker, etc.
At the first position, the longitudinal direction of the main body 30 may be substantially parallel with the longitudinal direction of the external object 2.
At the second position, the longitudinal direction of the main body 30 may form various angles with the longitudinal direction of the external object 2. For example, at the second position, the longitudinal direction of the main body 30 may form an angle in a range of 0 degrees to 180 degrees with the longitudinal direction of the external object 2. In the case where the external object 2 is, for example, a temple of an eyeglass frame, at the second position, the longitudinal direction of the main body 30 may form an angle in a range of 30 degrees to 90 degrees with the longitudinal direction of the external object 2 for the user's convenience.
The first distance between the main body 30 and the plane including the side surface 11 may be larger than the second distance.
According to various embodiments of the present invention, in the case where the user uses the rotary device 1 in the state where the rotary device 1 is attached to the external object 2, the main body 30 may be made to be in contact with the user's ear or face. When the user does not use the rotary device 1, the main body 30 may be completely separated from the user's body. As the main body 30 moves in the x-axis direction as illustrated in FIG. 3, the main body 30 may be capable of moving toward or away from the external object 2.
FIGS. 4A and 4B are exploded perspective views of a rotary device according to one embodiment of the present disclosure.
According to one embodiment of the present disclosure, a rotary device 300 may include a binding unit 310, an stationary unit 320, a rotary unit 330, and a main body 340.
The binding unit 310 may be coupled to an external object 2 such as a temple of an eyeglass frame. The stationary unit 320 may be connected to the binding unit 310. The rotary unit 330 may be rotatably connected to the stationary unit 320. The main body 340 may be coupled to the rotary unit 330.
According to one embodiment, the binding unit 310 may be connected or coupled to an external object, such as an eyeglass frame, through shrink fitting in a clip manner, and the rotary device 300 may be freely detachably attached to or fixed to the external object 2. The method of connecting the binding unit 310 to the external object 2 is not limited, and may be connected to the external object 2 through various methods.
The stationary unit 320 is positioned adjacent to one side surface 311 of the binding unit 310.
The stationary unit 320 is interposed between the binding unit 310 and the rotary unit 330 to allow the binding unit 310 and the rotary unit 330 to be indirectly connected with each other. The rotary unit 330 is rotatable about the stationary unit 320. The rotary device 300 may include a component or a shape to prevent the rotary unit 330 from being freely rotated about the stationary unit 320. For example, a stop pin 322 may be used for controlling the rotation range of the rotary unit 330 in relation to the stationary unit 320. When an end of the stop pin 322 penetrates the rotary unit 330 and then is inserted into the stationary unit 320, the rotation of the rotary unit 330 in relation to the stationary unit 320 may be limited. The spring 323 may provide an elastic force to allow the end of the stop pin 322 to be inserted into the stationary unit 320.
According to one embodiment, a first end 340a (an upper end in the drawing) of the main body 340 may be formed with a coupling portion 341 to be coupled to the rotary unit 330. On a second end 340b (a lower end in the drawing) of the main body 340, an additional module 361, such as a sound module, may be mounted.
Although the main body 340 is illustrated as a separate component coupled to the rotary unit 330, the main body 340 may be formed to extend from an region of the rotary unit 330. For example, the main body 340 may be formed integrally with the rotary unit 330.
A first position of the rotary unit 330 according to one embodiment of the present disclosure is described with reference to FIG. 5. A second position of the rotary unit 330 according to one embodiment of the present disclosure is described with reference to FIG. 6.
FIGS. 5 and 6 illustrate a state where the rotary unit 330 illustrated by dotted lines is removed from the main body 340.
According to one embodiment, the rotary unit 330 may be configured to be rotatable between the first position and the second position set in relation to the stationary unit 320. The overall shape of the stationary unit 320 may be a cylindrical shape. The rotary unit 330 may have a cylinder shape that accommodates the stationary unit 320.
In the state where rotary device 300 is coupled to an external object (e.g., a temple of an eyeglass frame) 2, the first position may be a position where the main body 340 is parallel with or overlaps the external object 2. At the second position, the main body 340 may be approximately perpendicular to the external object 2. The distance of the rotary unit 330 spaced apart from the side surface of the binding unit 310 at the first position may be larger than the distance of the rotary unit 330 spaced apart from the side surface of the binding unit 310 at the second position. For example, at the second position where the main body 340 is perpendicular to the longitudinal direction of the external object 2, the main body 340 comes in close contact with the external object 2, and at the second position where the main body 340 is parallel with the longitudinal direction of the external object 2, the main body 340 is moved away from the external object 2. The user may rotate the rotary unit 330 or the main body 340 between the first position and the second position. At the second position, the additional module (e.g., sound module) mounted on the main body 340 may be in the state where it is operated. At the first position, the additional module (e.g., the sound module) may be in the state where it is not operated.
According to one embodiment, the rotary unit 330 may include an insertion part 331. The insertion part 331 refers to a region where at least a part of the stationary unit 320 is inserted. When the stationary unit 320 is inserted into the insertion part 331, the rotary unit 330 and the stationary unit 320 may be coupled with each other. A guide slot 332 may be formed on the inner circumferential surface of the insertion part 331. A guide projection 321 may be formed on the external surface of the stationary unit 320 to be movable along the guide slot 332.
When the rotary unit 330 rotates in relation to the stationary unit 320, the guide projection 321 moves along the guide slot 332, and the rotary unit 330 is movable perpendicular to the stationary unit 320. For example, since a part of the guide slot 332 is formed spirally in relation to the rotary axis direction, the guide projection 321 may be rotationally or rectilinearly moved in relation to the rotary axis of the rotary unit 330. The guide projection 321 may move while being spirally rotated, the rotary unit 330 such that is rotatable or rectilinearly movable in the rotary axis direction with respect to the stationary unit 320.
According to one embodiment, the guide slot 332 may be formed on the outer circumferential surface of the stationary unit 320. A guide projection 321 may be formed on the inner circumferential surface of the insertion part 331 to be movable along the guide slot 332, and the rotary unit 330 is rotatable with respect to the stationary unit 320.
The guide slot 332 may consist of an inclined slot 333 and a peripheral slot 334 as described later with reference to FIG. 6.
FIG. 7 is a view for describing the operation of the stop pin 322 according to one embodiment of the present disclosure.
According to various embodiments of the present disclosure, the stop pin 322 may be used so as to control the rotation range of the rotary unit 330 with respect to the stationary unit 320.
The stationary unit 320 includes a pin installation part 324. In the pin installation part 324, the stop pin 322 and a spring 323 configured to provide an elastic force to the stop 322 may be inserted and installed. In addition, the pin installation part 324 may include a through-hole 325 extending from the interior of the pin installation part 324 to the outer circumferential surface of the stationary unit 320. The stop pin 322 may be positioned to penetrate the through-hole 325, and one end of the stop pin 322 may protrude from the outer circumferential surface of the stationary unit 320.
At least one stop recess 336 may be formed on the inner circumferential surface of the insertion part 331 of the rotary unit 330. In the state where the stationary unit 320 is inserted into the rotary unit 330, one end of the stop pin 322 may be inserted into the stop recess 336. The rotation of the rotary unit 330 with respect to the stationary unit 320 may be controlled or limited, for example, by the interaction of the stop pin 322 and the stop recess 336.
In order to ensure that the stop pin 322 is easily separated from the stop recess 336, the one end of the stop pin 322 inserted into the stop recess 336 may be formed in a hemispherical shape. In the state where the one end of the stop pin 322 is inserted into the stop recess 336, the rotation of the main body 340 with respect to the stationary unit 320 may be limited, but when the user applies a force to the main body 340 to rotate the main body 340, the one end of the stop pin 322 may be released from the stop recess 336. When the rotary unit 330 is rotated, the stop pin 322 may be introduced into the stationary unit 320, and the one end of the stop pin 322 may come in contact with the inner circumferential surface of the rotary unit 330. For example, when the main body 340 is at the first position, the one end of the stop pin 322 may be positioned in the first stop recess 336a. When the main body 340 started to rotate from the first position, the one end of the stop pin 322 may be slid while being in contact with the inner circumferential surface of the rotary unit 330 during the rotation. When the rotary unit 330 is located at the second position, the one end of the stop pin 322 may be inserted into the second stop recess 336b by the elastic force provided by the spring 323. At the second position, the rotation of the rotary unit 330 with respect to the stationary unit 320 may also be controlled or limited.
According to one embodiment, two or more stop recesses 336 may be formed on the inner circumferential surface of the rotary unit 330.
Referring to FIG. 6, a part of the guide slot 332 may be formed to be inclined. According to one embodiment, the guide slot 332 may consist of an inclined slot 333 and a peripheral slot 334. The inclined slot 333 may be formed on the inner circumferential surface of the insertion part 331 to be inclined. The peripheral slot 334 may be formed to extend from the inclined slot 333, and formed along the periphery of the inner circumferential surface of the insertion part 331.
When the guide projection 321 moves along the inclined slot 333, the rotary unit 330 is moved toward or away from the side surface of the binding unit 310. For example, when the guide projection 321 moves along the inclined slot 333, the main body 340 may be moved toward or away from the external object 2, such as an eyeglass frame. When the guide projection 321 is moved along the inclined slot 333, the additional module (e.g., a sound module) mounted on the main body 340 may be moved toward or away from the user's face.
FIGS. 8A and 8B are exploded perspective views illustrating a rotary device 400 according to one embodiment of the present disclosure, FIG. 9 is a view illustrating an operation state of the rotary device, and FIG. 10 is a view for describing an operation state of a guide cam and a rotary cam of the rotary device 400 of FIG. 8.
According to one embodiment of the present disclosure, the rotary device 400 may include a binding unit 410, a stationary unit 420, a main body 430, and/or a guide body 440.
The binding unit 410 may be coupled to an external object 2, such as an eyeglass frame. The stationary unit 420 may be connected to the binding unit 410. The main body 430 may include a rotary unit rotatably connected to the stationary unit 420 on one side, and an additional module 461 (see FIG. 11) on the other side. The guide body 440 may be coupled to a rotary unit of the main body 430.
Referring to FIGS. 9 and 10, the main body 430 may be connected or coupled to be rotatable between a first position and a second position set with respect to the stationary unit 420. For example, at the first position where the rotary device 400 is coupled to the external object 2, such as a temple, the rotary unit 330 (see FIGS. 4 to 7) of the main body 430 may be parallel with the longitudinal direction of the external object 2. At the second position, the rotary unit of the main body 430 may be approximately perpendicular to the longitudinal direction of the external object 2.
The distance of the rotary unit of the main body 430 spaced apart from a side surface of the binding unit 410 at the first position may be larger than the distance of the rotary unit of the main body 430 from the side surface of the binding unit 410 at the second position.
According to one embodiment, the guide body 440 is positioned to be in contact with the rotary unit of the main body 430 in the region opposite to the region where the stationary unit 420 and the rotary unit of the main body 430 are coupled to each other. The guide body 440 may guide the rotary unit of the main body 430 to be moved toward or away from the binding unit 410.
According to one embodiment of the present disclosure, the rotary device 400 may further include a cam shaft 427 that forms a rotary axis of the rotary unit of the main body 430.
The cam shaft 427 may be installed through the rotary unit of the main body 430. One end 427a of the cam shaft 427 may be coupled to the stationary unit 420, and the other end 427b may be fixedly connected to the guide body 440.
Referring to FIG. 10, the guide body 440 may guide the main body 430. The rotary unit of the main body 430 may include a rotary cam 432. The rotary cam 432 may include a concave cam recess 433 and a convex cam projection 434. The guide body 440 may include a guide cam 442 corresponding to the rotary cam 432 of the rotary unit of the main body 430. The guide cam 442 may include a concave cam recess 443 and a convex cam projection 444.
The rotary cam 432 and the guide cam 442 may engage with each other. For example, the rotary cam 432 and the guide cam 442 may be rotatable about the same axis in the state where they are engaged with each other.
As the rotary cam 432 rotates with respect to the guide cam 442, the cam projection 434 of the rotary cam 432 may move in a sliding manner between the cam recess 443 and the cam projection 444 of the guide cam 442. According to one embodiment, when the main body 430 is located at the first position, the cam projection 434 of the rotary cam 432 may be positioned adjacent to the cam recess 443 of the guide cam 442 between the cam recess 443 of the guide cam 442 and the cam projection 444 of the guide cam 442. When the main body 430 is located at the second position, the cam projection 434 of the rotary cam 432 may be positioned adjacent to the cam projection 444 of the guide cam 442 between the cam recess 443 of the guide cam 442 and the cam projection 444 of the guide cam 442. When the main body 430 is located at the first position, the cam projection 444 of the guide cam 442 and the cam recess 433 of the rotary cam 432 may be engaged with each other. At the first position, the main body 430 may be spaced apart from the binding unit 410 or the external object 2 at a maximum or full extent or distance.
According to one embodiment, when a cylinder part 421 formed in the stationary unit 420 may be inserted into the insertion part 431 of the rotary unit of the main body 430. A spring 428 may be provided between the stationary unit 420 and the rotary unit of the main body 430. One end 428b of the spring 428 may be inserted into the cylinder part 421 of the stationary unit 420, and the other end 428a of the spring 428 may be inserted into the insertion part 431 of the rotary unit of the main body 430. The spring 428 may provide an elastic force to the main body 430 and the stationary unit 420. In addition, the spring 428 may provide an elastic or a biasing force that causes the main body 430 to be biased away from the stationary unit 420.
At the second position, the main body 430 may be perpendicular to a temple as the external object 2, in which state the cam projection 444 of the guide cam 442 and one end of the cam projection 434 of the rotary cam 432 come in contact with each other. At this time, since the spring 428 pushes the rotary unit of the main body 430 toward the guide body 440, a restoration force is generated to cause the cam projection 434 of the rotary cam 432 to move to the cam recess 443 of the guide cam 442. In order to prevent this, the angle between the first position and the second position may exceed 90 degrees.
In the case where the angle between the first position and the second position is 90 degrees, the main body 430 may approach the external object 2 to maximum. Thus, the angle between the first position and the second position may be similar to 90 degrees.
In order to prevent the reverse rotation of the main body 430, and allow the main body 430 to properly approach the binding unit 410, the angle between the first position and the second position may exceed 90 degrees.
According to one embodiment, the stationary unit 420 may guide the main body 430.
Although not specifically illustrated, for example, the guide cam 442 corresponding to the rotary cam 432 of the rotary unit of the main body 430 may be included in the stationary unit 420, the guide body 440 may include the cylinder part 421, and the spring 428 may be provided between the guide body 440 and the rotary unit of the main body 430.
FIG. 11 is a view for describing a stop recess 426 according to one embodiment of the present disclosure.
The stationary unit 420 may further include the stop recess 426. The second position of the main body 430 may be determined by the position of the stop recess 426. The main body 430 may include a stop projection 436 that catches or engages the stop recess 426 at the second position. When the stop projection 436 is caught or engages with the stop recess 426, the main body 430 is inhibited or prevented from rotating in the direction opposite to the direction directed from the second position to the first position.
FIG. 12 is a perspective view illustrating a rotary device 500 according to one embodiment of the present disclosure.
According to one embodiment of the present disclosure, the rotary device 500 may include two or more additional modules (e.g., a sound module and various sensors) mounted thereon.
The rotary device 500 may include a binding unit capable of being coupled to an external object 2, an stationary unit connected to the binding unit, and a rotary unit connected to be rotatable about one axis between a plurality of positions set with respect to the stationary unit. As the rotary unit is rotated with respect to the stationary unit, the rotary unit may sequentially move toward or away from one side surface of the binding unit at the plurality of positions. The rotary device 500 may include a main body 540 coupled to the rotary unit.
A first additional module 561 and a second additional module 562 may be mounted on one end 540a and on the other end 540b of the main body 540, respectively. At the first position, the rotary unit may be moved away from the external object, in which case the main body 540 may be positioned to be parallel with the external object. As being rotated from the first position, the main body 540 may be spaced apart from the external object 2 or come in close contact with the external object 2, in which the spacing and close contact may be sequentially performed.
The first additional module 561 and the second additional module 562 may be configured to be operated when they are located at a set operation position among a plurality of positions. A position where the first additional module 561 is parallel with the longitudinal direction of the external object 2 may be referred to as a first position, and a position rotated 90 degrees from the first position may be referred to as a second position. A position rotated 90 degrees from the second position may be referred to as a third position. The first position and the third position may form an angle of 180 degrees therebetween. A position rotated 90 degrees from the third position may be referred to as a fourth position. The second position and the fourth position may form an angle of 180 degrees therebetween. Alternatively, a plurality of positions may be defined as five or more positions. The main body 540 may include at least two additional modules. For example, the main body 540 may include two different sensor kinds, and the kind of sensor coming in contact with the user's face may be changed as the main body 540 is rotated. For example, when an HRM sensor is mounted as the first additional module 561 and a sound module is mounted as the second additional module 562, the HRM sensor and the sound module may be caused to selectively come in contact with the user's face as the main body 540 is rotated.
At the first position, the main body is parallel with the longitudinal direction of a temple as the external object 2, and at the second position, the first module 561 or the second module 562 is approximately perpendicular to the longitudinal direction of the temple as the external object 2. The user may rotate the main body 540 by a set unit (e.g., a 90 degree unit), and the first additional module 561 and the second additional module 562 may be adjusted to come selectively close contact with the user's face.
According to one embodiment, it is possible to adjust the operation of the first additional module 561 or the second additional module 562 to be operated as the main body 540 is rotated. When the sound module or the HRM sensor is in close contact with the user's face at the second position or the fourth position, an adjustment may be made so that the sound module or the HRM sensor is operated. The operation of the sound module or the HRM sensor may be stopped at the first position or the third position. A camera may be additionally mounted on the main body 540, and the camera may be directed in the user's visual line at the first position. For example, at the first position, the camera may photograph in the same direction as the user's visual line.
In the prior art, in order to use a camera, a sound device, or a HRM sensor, it was necessary for the user to use each of separately provided devices. According to the rotary device of the present disclosure, it is now possible to conveniently carry the devices without the necessity of providing respective devices separately, and each function can be selected through a simple rotating operation.
FIG. 13 is a perspective view of a rotary device 600 according to one embodiment of the present disclosure.
Since the skeletal muscles of faces of persons are different from each other, the position of a sound device should be adjustable according to the shape of the user's face. For example, in the case where the sound module 661 is a bone conduction speaker, the position of the sound module 661 should be adjustable to be correctly in contact with a specific position of the user's face. The position of the binding unit 610 to be coupled to the external object 2 may be changed. However, only with the coupling position of the binding unit 610, it is difficult to correctly determine the position where the bone conduction speaker is in contact with the user's face.
The rotary device 600 may be further provided with a rotary member 650 to adjust the rotation angle between the binding unit 610 and the main body 640.
FIG. 14 is a view illustrating a use state of the rotary device 600 according to one embodiment of the present disclosure.
The relative angle between the temple as the external object 2 and the main body 640 may be adjusted through the rotation of the rotary member 650. Although not illustrated, according to one embodiment, the rotary device 600 may include a stationary unit. The stationary unit may be configured to have the same constitution as those of the above-described embodiments. The rotary member 650 may be positioned between the binding unit 610 and the stationary unit, and may be capable of adjusting the angle between the binding unit 610 and the stationary unit. For example, the operation position of the sound module 661 (or the second position) may be set as the initial position A through the rotary member 650. Through this, the operation position of the sound module may be adjusted to be suitable for the shape of the user's face.
FIG. 15 is a perspective view of a rotary device 700 according to one embodiment of the present disclosure.
As in FIG. 13, the position where the binding unit 710 is coupled to an external object 2 can be changed.
Within a main body 740, not only an additional module, such as a sound module 761, a sensor 762, such as a touch sensor or a proximity sensor, may be additionally included. That is, through the sensor 762, it may be recognized that the sound module 761 of the main body 740 is contact with the user's skin, and the second position or the operation position of the sound module 761 may be sensed.
According to one embodiment, it is possible to sense, through the sensor 762, that the additional module is not in contact with the user's skin and to stop the operation of the sound module 761 or to turn off the power of the sound module 761. On the contrary, when it is recognized, through the sensor 762, that the additional module is in contact with the user's skin, the power of the sound module 761 may be turned on.
The rotation of the rotary device 700 may be sensed not only through the sensor 762, but also through a separate physical switch, and the management of power through this may be enabled not only through the rotary device 700, but also through a main device which may be connected with the rotary device 700.
According to one embodiment, the operation of the rotary device may be controlled through an operation of a switch or an application of the main device. Alternatively, the application operated in the main device may be controlled through the operation of the rotary device 700.
