Various embodiments of the present invention relate to an electronic device. For example, various embodiments of the present invention relate to an electronic device that is capable of performing communication with other electronic devices, a server, or the like through, for example, a network environment.
With the development of electric, electronic, and information/communication technologies, various types of electronic devices have been variously utilized in daily lives. For example, an early mobile communication service provided a voice call function, a simple message transmission/reception function, or the like, but the service regions of the mobile communication service are being gradually expanded up to various network services, such as Internet, multimedia services, and banking/security services. In addition, mobile communication terminals have been improved to such an extent so as to enable various service connections while being miniaturized to be portable any time, and it has become possible to set or control electronic devices located at different spaces through a mobile communication terminal and a network.
Electronic devices that are portable by a user are gradually developed to be wearable on a human body, through which it is expected that various types of services will be provided even in medical fields, such as health care. For example, a medical service (health care of a patient have a disease, such as diabetes or high blood pressure), virtual reality, augmented reality, and so on can be variously implemented through a wrist-wearable or face-wearable electronic device. Such body-wearable electronic devices may be in the form of a wrist watch, eyeglasses, a necklace, or the like, and may be configure to be wearable on an arm, a leg, or any portion of a user's body.
By reducing the size and weight of an electronic device, it is possible to make the electronic device wearable on a body, while providing a convenient wearing feeling to a user. In addition, as the size and weight of the electronic device are reduced, some functions of the electronic device may be limited. For example, an input/output device, such as a display device or a keyboard, may be made smaller than that of an ordinary mobile communication terminal or a tablet PC, or may be omitted, and battery capacitance or the like may be considerably reduced. In addition, in the body-wearable electronic device, there are more constraints in designing and arranging an antenna or the like by the reduced space. Accordingly, in implementing a body-wearable electronic device, many efforts may be needed to maximizing or optimizing the performance of the electronic device while reducing the size and weight of the electronic device.
Thus, various embodiments of the present invention are to provide an electronic device that enables an internal space to be efficiently used while being reduced in size and weight.
In addition, various embodiments of the present invention are to provide an electronic device that enables antennas to be easily arranged therein while being miniaturized to be wearable on a body.
Further, various embodiments of the present invention are to provide an electronic device that is capable of providing an improved wearing feeling by suppressing or alleviating internally generated heat from being transferred to a body.
According to various embodiments of the present invention, an electronic device may include: a main body that is made of a conductive material and has opposite ends extending in a curved form to be adjacent to each other so as to form a loop shape; a communication module disposed on the main body; a feeding line extending from the communication module, and disposed across a gap between the opposite ends of the main body; and at least one connection terminal that connects the feeding line to the main body.
The main body may receive a feeding signal from the communication module through the feeding line, and may transmit/receive a wireless signal.
In the electronic device as described above, the main body may have a ring shape, and at least one of a battery, a power management module, a motion sensing sensor module, a vibration module, a sound module, and a Micro Controller Module (MCU) is disposed on an inner or outer surface of the main body may be arranged along a circumferential direction of the main body together with communication module.
In addition, an electronic device according to various embodiments of the present invention transmits/receives a Radio Frequency (RF) signal. The electronic device may include:
An electronic device according to various embodiments of the present invention may have, for example, a ring shape that is wearable on a user's finger, and electronic components, such as a communication module and a battery, may be arranged along the circumferential direction of the ring-shaped main body. For example, electronic components, which correspond to a function intended to implement through the electronic device, may be properly arranged. In addition, by cutting a portion of the loop-shaped (or ring-shaped) main body to form a narrow gap, and providing a feeding line across the narrow gap, the gap may be utilized as a radiating conductor (e.g., an antenna). Thereby, the electronic device may be equipped with a wireless communication function while being miniaturized to be wearable on a body. In addition, by forming metal fins on the main body and causing the metal fins to be in contact with the electronic components, and by further increasing a contact area with air, it is possible to improve a heat radiation performance. For example, it is possible to stabilize the operation of the electronic device. Further, by forming wrinkles or curves on a portion to be in contact with the user's body to reduce a body contact area, and securing a route through which air can flow, it is possible to further improve the wearing feeling and the heat radiating performance of the electronic device.
Hereinafter, various embodiments of the present invention will be described with reference to the accompanying drawings. However, it should be understood that there is no intent to limit the present invention to the particular forms disclosed herein; rather, the present invention should be construed to cover various modifications, equivalents, and/or alternatives of embodiments of the present invention. In describing the drawings, similar reference numerals may be used to designate similar constituent elements.
In the various embodiments of the present invention, the expression “A or B”, “at least one of A or/and B”, or “one or more of A or/and B” may include all possible combinations of the items listed. For example, the expression “A or B”, “at least one of A and B”, or “at least one of A or B” refers to all of (1) including at least one A, (2) including at least one B, or (3) including all of at least one A and at least one B.
The expression “a first”, “a second”, “the first”, or “the second” used in various embodiments of the present invention may modify various components regardless of the order and/or the importance but does not limit the corresponding components. For example, a first user device and a second user device indicate different user devices although both of them are user devices. For example, a first element may be termed a second element, and similarly, a second element may be termed a first element without departing from the scope of the present invention.
It should be understood that when an element (e.g., first element) is referred to as being (operatively or communicatively) “connected,” or “coupled,” to another element (e.g., second element), it may be directly connected or coupled directly to the other element or any other element (e.g., third element) may be interposer between them. In contrast, it may be understood that when an element (e.g., first element) is referred to as being “directly connected,” or “directly coupled” to another element (second element), there are no element (e.g., third element) interposed between them.
The expression “configured to” used in the present invention may be exchanged with, for example, “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to”, or “capable of” according to the situation. The term “configured to” may not necessarily imply “specifically designed to” in hardware. Alternatively, in some situations, the expression “device configured to” may mean that the device, together with other devices or components, “is able to”. For example, the phrase “processor adapted (or configured) to perform A, B, and C” may mean a dedicated processor (e.g., embedded processor) only for performing the corresponding operations or a generic-purpose processor (e.g., central processing unit (CPU) or application processor (AP)) that can perform the corresponding operations by executing one or more software programs stored in a memory device.
In the present invention, the terms are used to describe specific embodiments, and are not intended to limit the present invention. As used herein, the singular forms are intended to include the plural forms as well, unless the context clearly indicates otherwise. In the description, it should be understood that the terms “include” or “have” indicate existence of a feature, a number, a step, an operation, a structural element, parts, or a combination thereof, and do not previously exclude the existences or probability of addition of one or more another features, numeral, steps, operations, structural elements, parts, or combinations thereof.
Unless defined differently, all terms used herein, which include technical terminologies or scientific terminologies, have the same meaning as that understood by a person skilled in the art to which the present invention belongs. Such terms as those defined in a generally used dictionary are to be interpreted to have the meanings equal to the contextual meanings in the relevant field of art, and are not to be interpreted to have ideal or excessively formal meanings unless clearly defined in the present specification. In some cases, even the term defined in the present invention should not be interpreted to exclude embodiments of the present invention.

Various electronic components may be disposed in the recess 215 formed on the outer surface of the main body 201 together with the printed circuit board 102. Because the arrangement of the electronic components is similar to the arrangement described above with reference to
The electronic device 200 may include a first insulator layer 203a formed on the inner surface of the main body 201 and a second insulator layer 203b formed on the outer surface of the main body 201. The main body 201 may be used as an antenna (e.g., a radiating conductor) of the electronic device 200, and the first insulator layer 203a may prevent the main body 201 from being directly in contact with the user's body. For example, the user may wear the electronic device 200 on a portion of the body (e.g., a finger), and in the state of being worn on the body, the first insulator layer 203a comes in contact with the user's skin so as to prevent the main body 201 from being directly in contact with the user's skin.
The first insulator layer 203a may be implemented to be exchangeable by the user. For example, the user may select or purchase the first insulator layer that is suitable for the size of a body portion on which the electronic device 200 is to be worn, and may couple the first insulator layer to the main body 201. Accordingly, the user may feel a convenient wearing feeling in wearing and using the electronic device 200.
The second insulator layer 203b may be formed on the outer surface of the main body 201, and may conceal and protect the printed circuit board 102 and the electronic components that are accommodated and mounted in the recess 215. The second insulator layer 203b may provide various patterns or decorations on the external appearance of the electronic device 200. At least a portion of the second insulator layer 203b may include an operating portion 113 made of a transparent or translucent material. The operating portion 113 may protrude more than other outer surface portion of the second insulator layer 203b, and may be positioned to correspond to the switch element disposed on the printed circuit board 102. According to various embodiments, at least one light emission element may be mounted on the printed circuit board 102. As the second insulator layer 203b is made of a transparent or translucent material, the light emitted from the light emission element may be emitted to the outside through the second insulator layer 203b.
The preceding embodiment has exemplified a structure in which light emission elements 121b are disposed within the narrow gap 111. In the structure of the electronic device 200 of the present embodiment, the printed circuit board 102 may be disposed on the outer surface of the main body 201 so that the arrangement of the light emission elements may be designed more freely. For example, among the opposite faces of the printed circuit board, light emission elements may be freely disposed on the face of the printed circuit board 102, which faces the outer surface of the main body 201. However, a communication module, a processor, or the like may be disposed on the printed circuit board 102, and the positions or the like of the other electronic components may be considered in arranging the light emission elements.
The printed circuit board 102 may include a feeding line 223a that extends from the communication module to a side of the narrow gap 111 across the narrow gap 111. The feeding line 223a may provide a feeding signal to the main body 201 from the communication module. The printed circuit board 111 may include a connection terminal 123a that connects the feeding line to the main body 201. For example, the main body 201 may receive a feeding signal through the feeding line 223a and the connection terminal 223c.
According to various embodiments, the electronic device 200 may further include a second feeding line 223b. The second feeding line 223b may extend from the communication module to the other side of the narrow gap 111, without passing across the narrow gap 111. The second feeding line 223b may be connected to the main body 201 at the other side of the narrow gap 111 through the second connection terminal 223d. Thereby, the main body 201 may receive a differential ratio frequency signal from the communication module through the first and second feeding lines 223a and 223b.
The electronic device 300 according to the present embodiment is different from those of the preceding embodiments in that the main body 301 is implemented by two pieces or rings 301a and 301b. For example, the main body 301 may be completed by coupling the two rings 301a and 301b to each other, and the printed circuit board or the above-described electronic components may be completely accommodated within the main body 301. In the present embodiment, it is exemplified that the main body 301 has a closed loop shape, but similar to those of the preceding embodiments, the electronic device 300 may include a narrow gap and a feeding line extending across the narrow gap. In the state where the two rings 301a and 301b are coupled to each other, the main body 301 may include a recess that accommodates the printed circuit board or the electronic components. The recess may be formed on the inner or outer surface of the main body 301. On the inner surface and/or the outer surface of the main body 301, an insulator layer 303 may be provided to prevent the user's body from being directly in contact with the main body 301, or to conceal and protect the printed circuit board and the electronic components disposed on the main body 301. According to various embodiments, each of the rings, which form the main body 301, may be made of a conductive material, and may be used as an antenna by being fed with a power from the communication module. The rings 301a and 301b may be manufactured and exchanged to be suitable for an antenna specification that is required by the electronic device 300.
