The housing 10 may be arranged with at least one key 11. Furthermore, the housing 10 may comprise a bonding portion 15 for attaching the strap 3. However, the constitution of the present invention is not limited to this, and for example, the case 10 and the strap 3 may be formed integrally.
In addition, although not shown, at least one sensor may be disposed at the body 2. For example, various health management-related sensors such as a heartbeat measurement sensor that can measure the physical condition of the user may be provided.

Further, the housing 10 may include a transparent outer cover 14 and a metal outer ring 12 used as a decoration member (decoration).
The transparent outer cover 14 is disposed on a display unit 20 described below so as to display information displayed in the display unit 20 to the outside. In addition, in the case where the electronic apparatus 1 is implemented in a touch-input manner, the transparent cover 14 may contain a touch panel.
The metal bezel 12 may be disposed along the periphery of the display unit 20.
In the present embodiment, the metal outer ring 12 is formed in a closed loop (ring) shape or a ring shape (ring). However, the constitution of the present invention is not limited to this. For example, the following various variations can be implemented: the metal outer ring 12 is formed in a ring shape in which a part is cut off, or is formed in an arc shape.
The main body 2 may include a display unit 20, a battery 30, a circuit unit 40, and a wireless charging unit 50.
The display unit 20 is disposed inside the casing 10 in such a manner that the display surface faces the transparent outer cover 14 of the casing 10. The display unit 20 displays diverse information including time information to a user. For this purpose, the display unit 20 may be a liquid crystal display such as an LCD, but is not limited to this and may be configured as a pointer type having an hour hand and a minute hand.
The battery 30 may be a rechargeable battery 30 as a power supply unit, and in this case, the battery may be charged by receiving power from the outside through a wired or wireless manner.
For this purpose, a plurality of charging terminals (not shown) that are in electrical and physical contact with pins (pins) of a charging device (not shown) that supplies electric power may be provided on one side (e.g., the rear side) of the main body 2.
Further, in order to wirelessly charge the battery 30, a wireless charging section 50 may be provided inside the main body 2.
The circuit unit 40 may be configured to mount various components (not shown) on the circuit substrate 42, operate the electronic device 1, and display information on the display unit 20.
The circuit unit 40 includes at least one chip antenna 44.
The chip antenna 44 is an antenna for short-range communication, and is attached to the circuit board 42 of the circuit unit 40. Specifically, the chip-type antenna 44 of the present embodiment may perform at least one of Radio Frequency Identification (RFID), Near Field Communication (NFC), and Magnetic Security Transmission (MST).
Fig. 5 is a perspective view schematically illustrating a chip-type antenna according to an embodiment of the present invention.
Referring to fig. 5, the chip-type antenna 44 according to the present embodiment includes a core 100, a coil 200, and a terminal portion 300.
The core 100 may be formed of a ferrite (ferrite) material, or may be formed of a ferrite hybrid material. For example, the core 100 may be formed by sintering ferrite powder, or may be manufactured by injection molding a resin mixture containing ferrite powder.
Further, the core 100 may be prepared by laminating a plurality of ceramic sheets having ferrite as a main component and then pressing/sintering.
The core 100 may be formed in a rod shape having a quadrangular cross section as a whole, but is not limited thereto, and may be provided in various shapes according to the structure and design requirements.
The core 100 according to the present embodiment can be distinguished as: a winding part 110 around which the coil 200 is wound; the terminal portion 120 is formed to have an enlarged cross-sectional area at both ends of the winding portion 110.
The terminal portion 120 is formed to have a thickness greater than that of the wire winding portion 110. Therefore, a step is formed at a portion of the core 100 where the terminal portion 120 and the wire winding portion 110 are connected, and a lower surface of the terminal portion 120 is disposed in such a manner as to protrude more downward than a lower surface of the wire winding portion 110.
The terminal pad 300 is formed of a conductive material, and can be bonded to the circuit board 42 using a conductive adhesive such as solder as an intermediate.
The winding portion 110 of the core 100 is wound with a coil 200. For example, the coil 200 may be wound in a spiral (helical) form or a helical (helical) form along the length direction of the core 100. But is not limited thereto.
The coil 200 is formed in a wire form and wound around the core 100. However, the present invention is not limited to this, and the coil may be formed in the form of a flat wire (edgewise coil), a flat plate coil (flat type coil), or a rectangular wire (rectangular wire).
Both end portions of the coil 200 are connected to terminal pads 300 disposed at both ends of the core 100, respectively.
A protective resin 400 may be disposed on the coil 200.
The protective resin 400 performs a function of insulating the coil 200 and protecting the coil 200, and may be applied to the entire surface of the core 100, or the protective resin 400 may be applied to only one surface of the core 100 as in the present embodiment.
The protective resin 400 may be formed by applying a resin in a liquid state and then hardening it. As a material of the protective resin 400, a resin such as an epoxy resin may be used, or a ferrite powder having magnetism may be mixed with the resin and used. But is not limited thereto.
In addition, as described above, the electronic apparatus 1 according to the present embodiment includes the metal outer ring 12. The metal outer ring 12 may reduce the radiation performance of the antenna due to the characteristics of the material.
Therefore, the chip-type antenna 44 according to the present embodiment may be disposed at a position spaced apart from the metal bezel 12 by a predetermined distance and on the circuit substrate 42 in such a manner that the longitudinal direction of the core 100 is parallel to the longitudinal direction of the strap 3 in order to minimize the reduction of radiation performance by the metal bezel 12. Further, the chip-type antenna 44 may be mounted on the circuit substrate 42 at a position adjacent to the strap 3.
In the case where the chip-type antenna 44 is disposed at the center of the circuit substrate 42, the magnetic field generated by the chip-type antenna 44 is shielded by the metal bezel 12, and thus the radiation performance may be greatly reduced. Therefore, in order to enable the magnetic field generated in the chip-type antenna 44 to easily form a magnetic circuit, the chip-type antenna 44 according to the present embodiment is to be disposed at a position adjacent to the outline of the circuit substrate 42, rather than at the center or inside of the circuit substrate 42. Further, the chip antenna 44 is disposed so that the longitudinal direction thereof crosses the metal bezel 12.
As the chip-type antenna 44 is attached to the above-described position, a magnetic path of the magnetic field generated by the chip-type antenna 44 is formed by the space outside the metal bezel 12, the inner hole of the metal bezel 12, and the like.
Fig. 6 is a diagram schematically illustrating a magnetic field of the chip-type antenna according to the embodiment of the present invention, in which arrows indicate a magnetic path of the magnetic field generated by the chip-type antenna. Referring to fig. 6, the magnetic field generated by the chip antenna 44 is formed so as to surround the metal bezel 12.
In order to form the magnetic field as described above, the chip-type antenna 44 needs to be disposed apart from the metal bezel 12. For example, the chip-type antenna 44 is arranged so that extension lines extending from both ends of the core do not contact the metal bezel 12. More specifically, the chip-type antenna 44 is arranged such that a plane extending the bonding surface of the circuit substrate 42 and the chip-type antenna 44 is isolated from the metal bezel 12.
Further, at least a portion of the chip-type antenna 44 is disposed within a lower region of the metal bezel 12. Here, the lower region represents a region where the metal outer ring 12 is vertically projected downward.
On this basis, the chip-type antenna 44 according to the present embodiment is arranged at a position adjacent to the first strip 3a of the first strip 32 and the second strip 3 b. When the electronic device 1 is located adjacent to other short-range communication devices 9 to perform short-range communication with each other in a state where the user wears the electronic device 1 on the wrist, as shown generally in fig. 7, the connection portion of the first strap 3a and the main body 2 is easily arranged at the position closest to the short-range communication device 9 due to the body structure.
Therefore, in the case where the chip-type antenna 44 is arranged on the first strip 3a side as in the present embodiment, since the chip-type antenna 44 is arranged closest to the short-range communication device 9, the communication performance can be improved.
The wireless communication part 50 may be disposed at the lowermost portion inside the housing 10. This is because, when the electronic apparatus 1 is charged, a wireless charging device (not shown) that supplies power is disposed at a lower portion of the electronic apparatus 1. Therefore, the position of the wireless charging section 50 may be changed corresponding to the position where the wireless charging device is disposed.
The wireless charging section 50 includes a film substrate 52 electrically connected to the circuit section 40 and a spiral coil pattern 54 formed on the film substrate 52. As the thin film substrate 52, a flexible substrate such as a film substrate can be used, but the present invention is not limited thereto.
In the present embodiment, both the wireless charging section 50 and the chip-type antenna 44 may be disposed on the lower surface of the circuit substrate 42. Further, the wireless charging section 50 and the chip-type antenna 44 may be arranged on approximately the same plane. However, the configuration of the present invention is not limited to this, and various modifications are possible, for example, the wireless charging unit 50 is disposed below the chip antenna 44.
The electronic apparatus 1 according to the present embodiment configured in the above-described manner uses the chip-type antenna 44 as an antenna for short-range communication. Further, the chip-type antenna 44 is arranged in parallel with the first strip 3a at a position adjacent to the first strip 3 a. Therefore, the magnetic field generated by the chip-type antenna 44 is not shielded by the ferrule 12 of the case 10, but is formed so as to surround the ferrule 12, and therefore, even if the ferrule 12 is provided, the radiation performance of the antenna can be improved.
Further, the electronic apparatus 1 in the form of a timepiece arranges the chip-type antenna 44 in the vicinity of the first strap 3a that is easily contacted with the short-range communication apparatus 9, and therefore, the communication efficiency can be maximized when contacted with the short-range communication apparatus 9.
In addition, the present invention is not limited to the above-described embodiments, and various modifications can be implemented in the present invention.
Fig. 8 is an exploded perspective view of an electronic device according to another embodiment of the present invention.
Referring to fig. 8, a helical antenna 60 (hereinafter, referred to as a second antenna) for short-range communication is included in addition to the chip-type antenna 44 (hereinafter, referred to as a first antenna) described above.
The second antenna 60 is formed in the form of a flexible substrate 62 having a spiral pattern 64 and is disposed between the display unit 20 and the transparent cover 14. Further, the display surface of the display unit 20 is disposed along an edge of the display unit 20 in such a manner as to be exposed upward. The present invention is not limited thereto and may be disposed at various positions between the display unit 20 and the battery 30 as long as it is disposed at the upper portion of the battery 30.
The second antenna 60 may be used for short-range communication similar to the first antenna 44. For example, the first antenna 44 may be used as a Near Field Communication (NFC) antenna, and the second antenna 60 may be used as a Magnetic Secure Transmission (MST) antenna. But is not limited thereto.
The electronic device of the present embodiment is provided with a wireless charging unit 50 for wireless charging. As in the above-described embodiment, the wireless charging portion 50 is disposed at the lower portion of the battery 30. Therefore, the second antenna 60 and the wireless charging portion 50 are respectively disposed at both sides of the battery 30. Also, the first antenna 44 is arranged between the second antenna 60 and the wireless charging section 50.
Accordingly, the electronic apparatus according to the present embodiment includes the first antenna 44, the second antenna 60, and the wireless charging unit 50, and performs wireless communication with the outside.
The wireless charging unit 50 and the second antenna 60 may be provided with magnetic sheets 55 and 65, respectively.
The first magnetic sheet 55 provided to the wireless charging portion 50 may be disposed between the film substrate 52 of the wireless charging portion 50 and the battery 30, specifically, between the film substrate 52 and the circuit substrate 42. Accordingly, when the electronic device is wirelessly charged, the magnetic path of the magnetic field generated by the wireless charging device is formed along the first magnetic sheet 55, thereby improving the charging efficiency.
Further, the second magnetic sheet 65 equipped to the second antenna 60 may be disposed between the second antenna 60 and the battery 30, and specifically, may be disposed between the display unit 20 and the battery 30. Accordingly, a magnetic path of the magnetic field radiated from the second antenna 60 is formed along the second magnetic sheet 65, so that the radiation efficiency can be improved.
With the above configuration, the wireless charging unit 50 can communicate with the outside through the lower direction of the main body, and the short-range communication using the second antenna 60 can communicate with the outside through the upper direction of the main body.
However, the first antenna 44, which is another antenna for short-range communication, is disposed between the first magnetic sheet 55 and the second magnetic sheet 65, so that the magnetic field generated by the first antenna 44 is difficult to radiate to the upper or lower portion of the electronic apparatus 1 due to the presence of the first magnetic sheet 55 and the second magnetic sheet 65. In particular, in the case of an antenna in which the first antenna 44 is formed in a spiral pattern like the second antenna 60 and the coil pattern 54 for wireless charging, these problems will be more serious.
However, the electronic apparatus according to the present embodiment constitutes the first antenna 44 by a chip-type antenna, and as with the above-described embodiment, by arranging the chip-type antenna 44 in a position adjacent to the first strip 3a in a manner parallel to the first strip 3a, the above-described problem can be solved.
Accordingly, since the magnetic field generated by the chip-type antenna 44 forms a magnetic path along the side surface of the electronic apparatus 1, the influence of the first and second magnetic pieces 55 and 65 disposed at the upper and lower portions of the chip-type antenna 44 can be minimized.
In the present embodiment, the case where only one chip-type antenna 44 is used is described as an example, but a plurality of chip-type antennas 44 may be used as needed. At this time, the plurality of chip-type antennas 44 may be respectively used for short-range communication different from each other.
Due to the above-described configuration, the first antenna according to the present embodiment can smoothly perform wireless communication with the outside even if it is arranged between the first magnetic sheet and the second magnetic sheet. Further, with the electronic apparatus 1 according to the present embodiment, even if at least three antennas and coils for wireless communication with the outside are arranged while having a small size wearable on the wrist, interference with each other can be minimized.
The electronic device according to the present invention described above is an example in which the metal outer ring is disposed so as to surround the display unit, but the configuration of the present invention is not limited to this. For example, the present invention can be similarly applied to a case where an internal member that is not an external structure of an electronic device and is made of a metal material is provided.
Further, in the present invention, a wrist-worn wearable electronic apparatus is shown, and a configuration in which a metal bezel and a chip-type antenna employing a decoration member (decoration) are arranged is described, but not limited thereto. For example, it is obvious that the present invention can be applied to various general electronic devices for communication, which are provided with a metal structure and a chip-type antenna corresponding to the metal structure, in addition to wearable electronic devices.
