[0089] According to one embodiment, in order to improve the aesthetics of the electronic device (101) and / or reduce the thickness of the electronic device (101) when folded, the housing (e.g., the housing (201) of FIG. 4) may be formed at least partially of a metal material. According to one embodiment, the housing (e.g., the housing (201) of FIG. 4) may include at least one conductive portion (not shown) segmented along at least a portion of a side surface. For example, the conductive portion (not shown) may be a frame formed of a metal material of the housing (e.g., the housing (201) of FIG. 4) and may be utilized as a radiator of an antenna. In one embodiment, one end of the conductive portion (not shown) may be segmented so that the conductive portion (not shown) may be utilized as a radiator of the antenna. However, the design of the segmented portion may be variously changed depending on the frequency utilization range of the antenna. In one embodiment, the rear surface (e.g., the rear plate (280) of FIG. 4) of the housing (e.g., the housing (201) of FIG. 4) may include a material that does not interfere with antenna radiation. For example, the rear surface of the housing (e.g., the housing (201) of FIG. 4) may include glass or an injection-molded material.

[0090] According to one embodiment, the electronic device (101) may further include an antenna structure, and the antenna structure may include a plurality of antennas. For example, the antenna may include a conductive portion (not shown), a feeding portion (not shown), or a ground portion (not shown). According to one embodiment, at least one component of the antenna structure (e.g., the conductive portion (not shown)) may be located in an area of ​​a housing (e.g., the housing (201) of FIG. 4).

[0091] According to one embodiment, the electronic device (101) may include an (electric) motor structure (300) that generates vibration. For example, the (electric) vibration motor applied to the electronic device (101) may be classified into a coin type having a thin thickness and a bar type having a long shape, depending on the shape of the motor. According to one embodiment, the motor structure (300) according to the present disclosure may be a coin type vibration motor. However, the type and shape of the motor structure (300) are not limited by the above embodiment.

[0092] According to one embodiment, the motor structure (300) may be disposed within a housing (e.g., the housing (201) of FIG. 4). According to one embodiment, the motor structure (300) may be disposed such that at least a portion thereof overlaps and / or is laminated with a conductive portion (not shown) that operates as a radiator of an antenna. For example, the conductive portion (not shown) and the motor structure (300) may at least partially overlap with each other with respect to the Z-axis of FIG. 4B. When the motor structure (300) operates, the counter weight (330) including metal rotates, and therefore, the distance between the counter weight (330) and the conductive portion (not shown) may not be constant.

[0093] According to one embodiment, the motor structure (300) may largely include a fixed part (301) (stator assembly) and a rotating part (302) (rotor assembly).

[0094] According to one embodiment, the fixed part (301) of the motor structure (300) may include an upper case (311) and a lower case (312) that are coupled to each other. According to one embodiment, a lower substrate (313) may be attached to the lower case (312), and a shaft (314) may be formed in the center of the lower case (312) in a form that penetrates the lower substrate (313). According to one embodiment, a lower end of a brush (315) may be connected to the lower substrate (313). The lower end of the brush (315) may be in contact with the lower substrate (313) and the upper end may be in contact with a commutator (e.g., 324 of FIG. 7) formed on the bottom surface of the rotating part (302), thereby supplying power applied from an external power source.

[0095] According to one embodiment, the fixing member (301) may include a ring-shaped magnet (316) fixed to an edge portion of the lower substrate (313). The magnet (316) may include an opening through which the shaft (314) passes. The magnet (316) may be magnetized with alternating N and S poles. For example, the magnets (316) may be arranged so that eight N and S poles are alternately arranged.

[0096] According to one embodiment, a rotating member (302) may be rotatably coupled to a shaft (314). According to one embodiment, the rotating member (302) may include a bearing (321) supporting the shaft (314), a coil assembly (322), an upper substrate (323), a commutator (e.g., a commutator (324) of FIG. 7), a counter weight (330), and an injection member (340).

[0097] According to one embodiment, the bearing (321) is placed on the rotation axis of the rotating part (302) and can be combined with the shaft (314) to ensure smooth rotation.

[0098] According to one embodiment, the coil assembly (322) may be configured to operate together with the magnet (316) to generate an electromagnetic force. The coil assembly (322) may include a first coil (322a) and a second coil (322b) spaced apart from each other by a predetermined distance and having a preset number of turns. For example, the angle formed between the center of each coil and the axis of the rotating part may be approximately 120 degrees or more and 170 degrees or less.

[0099] In one embodiment, the upper substrate (323) may be electrically connected to the coil assembly (322). In one embodiment, a counterweight (330) may be disposed between the first coil (322a) and the second coil (322b). In one embodiment, the injection member (340) may be in contact with at least a portion of the counterweight (330). For example, at least a portion of the injection member (340) and the counterweight (330) may be coupled. For example, the injection member (340) may be made of an insulating resin as an insulator.

[0100] According to one embodiment, the motor structure (300) can obtain mechanical vibration by rotating a rotating part (302) having an unbalanced mass. The rotating force can be generated by a structure that supplies current to the coil assembly (322) of the rotating part (302) through the contact point of a brush (315) and a commutator (e.g., the commutator (324) of FIG. 7). For example, when an external power source is applied, current flows to the coil assembly (322) disposed in the rotating part (302) through the brush (315) and the upper substrate (323), and the rotating part (302), whose center mass is eccentric due to the counterweight (330) due to the interaction of the field formed by the magnet (316) and the case, can thereby cause vibration by rotating around the shaft (314) with the bearing (321) therebetween. According to one embodiment, a rotary vibration motor structure (300) that generates vibration by rotating an eccentric rotating part (302) can determine the amount of vibration (vibration force) according to the design parameters of the motor, such as the eccentricity, the eccentric mass, and the driving rotation speed. For example, the amount of vibration (F) is the mass of the vibrating body (m), the eccentricity (e), and the square of the driving rotation speed ( ) can be proportional to ( ). For example, as the weight of the counterweight (330) increases, the amount of vibration generated may increase. At this time, the vibration direction of the rotating part (302) may be a plane (e.g., XY plane) perpendicular to the plane in which the rotating part (302) rotates, that is, the shaft (314). For example, the rotating part (302) may rotate in a first rotational direction (e.g., clockwise) and / or a second rotational direction opposite to the first rotational direction (e.g., counterclockwise) with respect to the shaft (314).

[0101] FIG. 6 is a drawing of a rotating part (302) of a motor structure (300) according to one embodiment disclosed in the present document, viewed from the upper direction (+Z direction). FIG. 7 is a drawing of a rotating part (302) of a motor structure (300) according to one embodiment disclosed in the present document, viewed from the lower direction (-Z direction). FIG. 8 is a perspective view of a rotating part (302) of a motor structure (300) according to one embodiment disclosed in the present document, viewed from the side. FIG. 9 is a cross-sectional view of a rotating part (302) of a motor structure (300) of FIG. 8 according to one embodiment disclosed in the present document, taken along line A-A'.

[0102] Referring to FIGS. 6 to 9, the rotating part (302) of the motor structure (300) may include a bearing (321), a coil assembly (322), a counter weight (330), a commutator (324), an upper substrate (323), an injection member (340), and / or a metal member (350). The configuration of the rotating part (302) of FIGS. 6 to 9 may be the same as all or part of the configuration of the rotating part (302) of FIG. 5. The structures of FIGS. 6 to 9 may be optionally combined with the structure of FIG. 5.

[0103] In one embodiment, the rotating part (302) may have an asymmetrical structure. In one embodiment, the rotating part (302) may be arranged eccentrically. In one embodiment, the rotating part (302) may have an unbalanced mass. For example, the rotating part (302) may have an unbalanced weight. In one embodiment, the rotating part (302) may be divided into a first region (3021) and a second region (3022) having different weights and / or structures. The first region (3021) and the second region (3022) may be divided based on a reference line (B) intersecting (vertically) the rotation axis. The rotating part (302) may be configured such that the weights of the first region (3021) and the second region (3022) are different, thereby generating vibration when rotating.

[0104] According to one embodiment, the injection member (340) may include a first injection portion (341) disposed in a first region (3021), and a second injection portion (342) extending from the first injection portion (341) and disposed in a second region (3022). According to one embodiment, the weight of the second injection portion (342) may be lighter than the weight of the first injection portion (341). For example, a volume and / or size of the second injection portion (342) may be smaller than a volume and / or size of the first injection portion (341). For example, a height of the second injection portion (342) may be lower than a height of the first injection portion (341). For example, the first injection portion (341) may have a semicircular shape, and the second injection portion (342) may have a shape in which at least a portion of the semicircle is etched.

[0105] In one embodiment, the counter weight (330) may be in at least a portion contact with the injection member (340). For example, the counter weight (330) may be coupled with the injection member (340). In one embodiment, the injection member (340) may include a recess (343) recessed downward (-Z direction) from an upper surface of the injection member (340). In one embodiment, the recess (343) of the injection member (340) may be formed in the first region (3021). In one embodiment, the counter weight (330) may be disposed in the recess (343) of the injection member (340). For example, the recess (343) of the injection member (340) may be formed to correspond to the shape and size of the counter weight (330). For example, the upper surface of the injection member (340) (e.g., one surface facing the +Z direction) and the upper surface of the counter weight (330) (e.g., one surface facing the +Z direction) may be substantially the same plane.

[0106] In one embodiment, the motor structure (300) may asymmetrically place a counterweight (330) of a first weight only on a portion thereof to increase the amount of vibration when the rotating part (302) rotates. In one embodiment, the counterweight (330) may be asymmetrically placed in the first region (3021) and the second region (3022). In one embodiment, the counterweight (330) may be located only in the first region (3021).

[0107] In one embodiment, since the amount of vibration is proportional to the weight of the counterweight (330), a high-density metal material may be used. For example, the counterweight (330) may include tungsten (w). For example, the first weight may be about 0.2, about 0.22, and / or about 0.215 g.

[0108] According to one embodiment, the rotating part (302) of the motor structure (300) may include a metal member (350) that is a conductive member to eliminate imbalance of radiation due to rotation from the antenna's perspective. For example, the metal member (350) may be placed on the injection member (340). At least a portion of the metal member (350) may be placed on the counterweight (330).

[0109] According to one embodiment, the metal member (350) may be positioned in an area where the counterweight (330) is not positioned. According to one embodiment, at least a portion of the metal member (350) may be positioned in the second area (3022). For example, the metal member (350) may be positioned in the first area (3021) and the second area (3022), or may be positioned only in the second area (3022). Accordingly, the conductive member of the rotating part (302), for example, the metal material, may be positioned substantially symmetrically. By positioning the metal material of the rotating part (302) substantially symmetrically, even when it is stacked with the antenna, there may be no radiation deviation depending on the position of the rotating part (302).

[0110] For example, if the counter weight (330) is conductive, combining the counter weight (330) and the metal member (350) can substantially distribute the conductivity of the first region (3021) and the second region (3021) in a balanced manner.

[0111] In one embodiment, the weight of the metal member (350) may be lighter than the weight of the counterweight (330). The weight of the metal member (350) may be a second weight that is lighter than the first weight. In order to minimize the reduction in vibration force due to the substantially symmetrical arrangement of the metal material of the rotating part (302), the weight of the metal member (350) may be lighter than the weight of the counterweight (330). The imbalance in the weights of the first region (3021) and the second region (3022) of the rotating part (302) may be maintained.

[0113] According to one embodiment, the mass of the rotating part (302) may be asymmetrically distributed, and the conductivity of the rotating part (302) may be symmetrically distributed.

The first region (3021) and the second region (3022) may be divided based on a reference line (B) intersecting (vertically) the rotation axis. The rotating part (302) may be configured such that the weights of the first region (3021) and the second region (3022) are different, thereby causing vibration when rotating. However, the conductivity of the rotating part (302) may be substantially balanced, so that the rotation may not interfere with the operation of the antenna.

In one embodiment, the counterweight (330) may be located only in the first region (3021).

[0158] In one embodiment, since the amount of vibration is proportional to the weight of the counterweight (330), a high-density metal material may be used. For example, the counterweight (330) may include tungsten (w). For example, the first weight may be about 0.2, about 0.22, and / or about 0.215 g.

[0159] According to one embodiment, the rotating part (302) of the motor structure (300) may include a metal member (750) that is a conductive member to eliminate imbalance due to rotation from the antenna's perspective. The metal member (750) may be placed on the injection member (340).

[0160] In one embodiment, the metal member (750) may be positioned in an area where the counterweight (330) is not positioned. In one embodiment, at least a portion of the metal member (750) may be positioned in the second area (3022). For example, the metal member (750) may be positioned only in the second area (3022). For example, the metal member (750) may be linearly positioned in the second area (3022). Accordingly, the conductive member of the rotating part (302), for example, the metal material, may be substantially symmetrically positioned. By substantially symmetrically positioning the metal material of the rotating part (302), even when it is stacked with the antenna, a radiation deviation depending on the position of the rotating part (302) may be eliminated or reduced.

[0161] In one embodiment, the weight of the metal member (750) may be lighter than the weight of the counterweight (330). The weight of the metal member (750) may be a second weight that is lighter than the first weight. In order to minimize the reduction in vibration force due to the substantially symmetrical arrangement of the metal material of the rotating part (302), the weight of the metal member (750) may be lighter than the weight of the counterweight (330). The imbalance in the weight of the first region (3021) and the second region (3022) of the rotating part (302) may be maintained.

[0162] According to one embodiment, the metal member (750) may include a copper sheet and may have a double injection structure formed integrally with the second injection part (342). Since the metal member (750) is joined to the second injection part (342) in a double injection structure, it may be advantageous in preventing falling or vibration during rotation of the rotating part (302).
