ELECTRONIC DEVICE WITH SEALING STRUCTURE

CROSS-REFERENCE TO RELATED APPLICATION

This application is based on and claims priority under 35 U.S.C. 119 to Korean Patent Application No. 10-2018-0108821 filed on Sep. 12, 2018 in the Korean Intellectual Property Office, the disclosure of which is herein incorporated by reference in its entirety.

BACKGROUND
1. Field

Various embodiments relate to a sealing structure that reduces the amount of vibration generated in a rear cover portion when an open-type speaker mounted on an electronic device is applied.

2. Description of Related Art

The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

Various types of speakers may be mounted on electronic devices, and a lower speaker that serve as a main speaker and an upper speaker (receiver) that transmits call sound may be arranged in an electronic device.

The lower speaker may be a closed-type speaker. In the case of a closed-type speaker, the speaker unit itself additionally has a separate enclosure structure. The separate enclosure may serve to prevent air pressure generated during operation of the speaker unit from spreading out.

Thanks to this role, the speaker enclosure plays an important role in speaker sound performance, and generally, it is possible to make the sound of a low frequency band better when the air volume of the enclosure is larger. In contrast, in the case of an open-type speaker such as an upper speaker (receiver), the speaker unit itself does not have an additional enclosure structure. In this case, the volume of the inner space of a set in which the open-speaker is mounted may also be used to play a role of a separate enclosure in a closed-type speaker unit.

However, since the upper speaker unit does not have a separate enclosure structure, the air inside the electronic device is compressed/expanded during the operation of the speaker. The compression/expansion of the air caused by the operation of the upper speaker is transmitted through the medium of air to the entire space inside the electronic device, causing vibration in all parts, and also causing great vibration in the rear cover (e.g., the rear glass) on the rear side of the electronic device.

When the rear glass vibration greatly occurs, when a user listens to music through the electronic device, the vibration may be transmitted through a hand holding the electronic device, which may cause discomfort. In addition, even when listening to music in the state in which the electronic device is mounted on a desk, there is a disadvantage in that additional noise may occur due to vibration between the rear glass on the rear side of the electronic device and the upper face of the desk.

In order to reduce the vibration of a rear glass to a predetermined level or lower, artificial audio tuning is performed to reduce the performance of the speaker at the upper end before product launch. This audio tuning results in reduction of sound performance of the speaker, thereby causing a great loss in terms of audio of the product.

SUMMARY

The disclosure provides an electronic device having a sealing structure that reduces vibrations of the rear glass caused by an open-type speaker.

In the sealed space formed as described above, since the compression/expansion force of air generated due to the upper speaker cannot be transferred to the sealed space by the sealing structure 690, occurrence of the vibration of the rear plate 680 can be greatly hindered.

The vibration of the rear plate 680 may occur most at the portion facing the vicinity of the center of the battery 650. This is caused due to the fact that the rigidity of the rear plate 680 in the vicinity of the battery 650 is weak, and when the adhesive tape is not applied, the compression/expansion of air may actively occur. In the case of the upper end of the rear plate 680, since the camera module, the fingerprint sensor, or the like exists, the rigidity of the upper end may be higher than that of the lower end. In consideration of the structure susceptible to vibration, the sealing structure 690 according to an embodiment may be formed along the periphery of the battery so as to seal the space between one face the battery 650 and the rear plate 680.

According to an embodiment, the sealing structure 690 formed around the battery 650, for example, along the guide rib 662 performs a function of a partition wall structure that is capable of preventing air flow at the upper end of the peripheral portion of the battery 650, thereby implementing a sealed space. For example, the sealing structure 690 may be formed as a wall-type partition wall structure using an elastic material or an adhesive material around the battery 650. The height of the partition wall may be formed to have a height so as to come in to close contact with the rear plate 680. Since the sealed space that faces one face of the battery 650 and the space that does not face the one face of the battery 650 are separated from each other by the sealing structure 690, the occurrence of vibration may be reduced in the rear plate 680 having the sealed space that faces the one face of the battery 650. This is because the sealing structure 690 blocks air flow, e.g., vibration.

FIG. 7A illustrates a perspective view of a position where a sealing structure 490 is formed on the upper end of a guide rib according to various embodiments. FIG. 7B illustrates a cross-sectional view of the state in which the sealing structure 490 according to various embodiments is disposed.

Referring to FIGS. 7A and 7B, a housing 710 according to various embodiments may include a battery accommodation portion 751, and the battery accommodation portion 751 may include a guide rib 762 for seating the battery 750. The guide rib 762 may have a vertical wall shape and may surround the battery 750. The guide rib 762 may support the side faces of the accommodated battery 750.

According to an embodiment, the sealing structure 790 may be disposed on the upper end of the guide rib 762, and may be in close contact with a rear plate 780. For example, the sealing structure 790 may be formed using an elastic material, such as rubber, silicon, or an adhesive material. The sealing structure 790 may be formed along the upper end face of the guide rib 762, and may be formed in a closed curve shape when viewed from above the rear plate 780. For example, the sealing structure 790 may be disposed by attaching or fixing a closed curve-shaped rubber to the rear plate 780 corresponding to the upper end face of the guide rib 762.

According to an embodiment, since the sealing structure 790 is divided into a sealed space s1 between one face of the battery 750 and the rear plate 780 and a non-sealed space s2, occurrence of vibration can be reduced in the rear plate 480 having the sealed space s1 facing the one face of the battery 750. This is because the sealing structure 790 blocks air flow, e.g., vibration. The sealing structure 790 may be made of an elastic material, and may be maintained in a squeezed state between the upper end of the guide rib 762 and the rear plate 780.

FIG. 8 illustrates a cross-sectional view of an area in which an elastic material is applied to the periphery of a guide rib using a dispensing device according to various embodiments.

Referring to FIG. 8, a housing 810 according to various embodiments may have a sealing structure (e.g., the sealing structure 790 illustrated in FIG. 7B) formed along the periphery of the battery (e.g., the battery 750 illustrated in FIG. 7B) through a dispensing process. A liquid adhesive resin may be applied to the periphery A1 of the battery using a dispensing device. According to an embodiment, a guide rib 862 in the periphery A1 of the battery 550 may be formed in a structure that increases the width and height compared to the conventional one. Since the sealed space (e.g., the sealed space s1 illustrated in FIG. 7B) that faces one face the battery 1 and the space that does not face the one face of the battery 1 (e.g., the non-sealed space s2 illustrated in FIG. 7B) are separated from each other by a sealing structure (e.g., the sealing structure 790 illustrated in FIG. 7B) implemented by the curing of the applied liquid adhesive resin, occurrence of vibration can be reduced in the rear plate (e.g., the rear plate 780 illustrated in FIG. 7B) having the sealing space that faces the one face the battery 750. This is because the sealing structure blocks air flow, e.g., vibration.

FIG. 9A illustrates a plan view of the state in which a conductive member 470 according to various embodiments is disposed. FIG. 9B illustrates a perspective view of a part of the state in which a conductive member 470 and a battery 550 according to various embodiments are disposed. FIG. 9C illustrates a perspective view of the state in which a conductive member 470 according to various embodiments is disposed. FIG. 9D illustrates a cross-sectional view of a sealing structure 490 according to various embodiments.

Referring to FIGS. 9A to 9D, the housing 910 according to various embodiments may include a battery accommodation portion 951, and the battery accommodation portion 951 may be provided with a guide rib 962 so that the battery 950 can be seated in the battery accommodation portion 951. According to an embodiment, a conductive member 970 may be disposed between the battery 950 and the rear plate 980.

According to an embodiment, the conductive member 970 may be a wireless charging pad, and may include at least one coil (e.g., the coil 472 illustrated in FIG. 4B) and a protective layer made of insulating material to protect the at least one coil 472. For example, the conductive member 970 may be formed in a thin plate shape, and may be disposed between the rear plate 980 and one face of the battery 950. The coil (e.g., the coil 472 illustrated in FIG. 4B) may be wound multiple times, and may have a flat plate shape.

The conductive member 970 according to an embodiment may be configured in a shape having an area sufficient to cover the battery 950. When viewed from above the battery 950, the conductive member 970 may be disposed to overlap the battery 950. According to an embodiment, the conductive member 970 may be formed in a shape having an area sufficient to cover the guide rib 962 formed around the battery 950. When viewed from above the battery 950, the conductive member 970 may be disposed to overlap the guide rib 962.

According to an embodiment, the protrusion height of the guide rib 962 formed in the support structure 960 is formed to be slightly larger than the thickness of the battery 950, so that the guide rib 962 can be disposed to come into close contact with the conductive member 970. The upper end of the guide rib 962 and a part of the conductive member 970 may be in close contact with each other in a closed curve shape to provide the sealing structure 990. The sealing structure 990 may be in a compressed state. Since the sealed space s1 that faces one face of the battery 950 and the space s2 that does not face the one face of the battery 950 are separated from each other by the sealing structure 990, the occurrence of vibration may be reduced in the rear plate 980 having the sealed space s1 that faces the one face of the battery 950. This is because the sealing structure 990 blocks air flow, e.g., vibration.

FIG. 10 schematically illustrates a block diagram of a disposed state of components of an electronic device having a large capacity battery according to various embodiments.

Referring to FIG. 10, an electronic device 1000 (e.g., the electronic device 100 illustrated in FIG. 1 or the electronic device 300 illustrated in FIG. 3) according to various embodiments may be disposed in the intermediate area 1012 of the housing 1010 in order to increase the capacity of a battery 1050. The battery 1050 may be disposed to have a size sufficient to occupy at least one-third of the housing 1010.

According to an embodiment, the housing 1010 may include an upper area 1011, an intermediate area 1012, and a lower area 1013. The upper area 1011 may have a receiver 1002 disposed at the upper end thereof, and a first printed circuit board 1004 may be disposed adjacent to the receiver (an open-type speaker). The battery 1050 may be disposed in the intermediate area 1012. The battery 1050 may occupy most of the intermediate area 1012. In the lower area 1013, a lower speaker 1008 (a closed-type speaker) may be disposed at the lower end, and a second printed circuit board 1006 may be disposed in the lower area 103. The first printed circuit board 1004, the battery 1050, and the second printed circuit board 1006 may be disposed so as not to overlap each other.

According to an embodiment, a sealing structure 1090 may be disposed at the point where the upper region 1011 and the middle region 1012 are separated from each other. A space s01 in which the receiver 1002 is disposed and a space s0 in which the battery 1050 is disposed may be spatially isolated from each other by the sealing structure 1090. For example, the sealing structure 1090 may extend along one edge of the battery 1050, and may be formed in the housing 1010 in a partition wall type like a vertical wall. However, the sealing structure 1090 is not limited to the partition wall type, and may be formed using an elastic material such as rubber, silicon, or an adhesive material. The sealed space s0 having the battery 1050 therein and the unsealed space s01 having a receiver may be separated from each other by the sealing structure 1090.

According to an embodiment, since the sealing structure is divided into a sealed space s0 in which the battery 1050 is disposed and the non-sealed space s01 in which the receiver 1002 is disposed are separated from each other by the sealing structure 490, occurrence of vibration can be reduced in the rear plate (e.g., the rear plate 480 illustrated in FIG. 4A) having the sealed space facing the one face of the battery 1050. This is because the sealing structure 1090 blocks air flow, e.g., vibration.

FIG. 11 schematically illustrates a block diagram of a disposed state of components of an electronic device having a large capacity battery according to various embodiments.

Referring to FIG. 11, an electronic device 1100 (e.g., the electronic device 1000 illustrated in FIG. 10) according to various embodiments may be disposed in the intermediate area 1112 of a housing 1110 in order to increase the capacity of a battery 1150. The battery 1150 may be disposed to have a size sufficient to occupy at least one-third of the housing 1110.

According to an embodiment, the housing 1110 may include an upper area 1111, an intermediate area 1112, and a lower area 1113. The upper area 1111 may have a receiver 1102 (an open-type speaker) disposed at the upper end thereof, and a first printed circuit board 1104 may be disposed adjacent to the receiver 1102. The battery 1150 may be disposed in the intermediate area 1112. The battery 1150 may occupy most of the intermediate area 1112. In the lower area 1113, a lower speaker 1106 (an open-type speaker) may be disposed at the lower end, and a second printed circuit board 1108 may be disposed in the lower area 1113. The first printed circuit board 1104, the battery 1150, and the second printed circuit board 1108 may be disposed so as not to overlap each other.

According to an embodiment, a first sealing structure 1190 may be disposed at a position at which the upper area 1111 and the intermediate area 1112 are spatially divided, and a second sealing structure 1192 may be disposed at a position at which the intermediate area 1112 and the lower area 1113 may spatially divided. A space s41 in which the receiver 1102 is disposed and a space s4 in which the battery 1150 is disposed may be spatially isolated from each other by the first and second sealing structures 1190 and 1192, and the space s4 in which the battery 1150 is disposed and the space s42 in which the lower stage speaker 1106 is disposed may be spatially isolated from each other by the second sealing structure 1192. For example, the first sealing structure 1190 may extend along one edge of the battery 1150, and may be formed in the housing 1110 in a partition wall type like a vertical wall. The second sealing structure 1192 may extend along another edge of the battery 1150, and may be formed in the housing 1110 in a partition wall type like a vertical wall. However, the first and second sealing structures 1190 and 1192 are not limited to the partition wall type, and may be formed using an elastic material such as rubber, silicon, or an adhesive material. The sealed space s4 having the battery 1150 therein and the unsealed spaces s41 and 42 having a receiver 1102 and a lower speaker 1106 therein may be separated from each other by the sealing structures 1190 and 1192.

According to an embodiment, by the sealing structures 1190 and 1192, occurrence of vibration can be reduced in the rear plate (e.g., the rear plate 480 in FIG. 4A) having the sealed space facing one face of the battery 1050. This is because the first and second sealing structures 1190 and 1192 block air flow, e.g., vibration transferred from the receiver.

FIG. 12A illustrates a plan view of a rear plate on which a sealing structure according to various embodiments is formed. FIG. 12B illustrates a bottom view of a housing on which a conductive member according to various embodiments is disposed. FIG. 12C illustrates a cross-sectional view of the state in which a sealing structure 490 according to various embodiments is disposed.

Referring to FIGS. 12A to 12C, an electronic device (e.g., the electronic device 100 illustrated in FIG. 1 or the electronic device 300 illustrated in FIG. 3) according to various embodiments may include a battery 1250 disposed in a housing 1210, a conductive member 1270, a rear plate 1280, and a sealing structure 1290.

According to an embodiment, the sealing structure 1290 may be formed on the rear plate 1280. For example, the sealing structure 1290 may be formed of a piece of double-sided tape using an adhesive material, a stepped structure of an injection-molded material, or a partition wall structure. According to an embodiment, the sealing structure 1290 may be disposed between a part of the battery 1250 and the conductive member 1270 and the rear plate 1280. The sealing structure 1290 may extend along the conductive member 1270 and an edge of the battery 1250, and may be formed in a closed curve shape when viewed from above the conductive member 1270.

According to an embodiment, the sealing structure 1290 may be formed while avoiding at least one coil (e.g., the coil 472 in FIG. 4A). When the conductive member 1270 is viewed from above, the sealing structure 1290 may be disposed so as not to overlap the at least one coil, or may be disposed in a shape that encloses at least one coil 472. The area in which the at least one coil is disposed may not overlap the sealing structure 1290.

According to an embodiment, the sealing structure 1290 may be disposed on the first face 1280a of the rear plate 1280 in a protruding shape having a thickness in the first direction {circle around (1)}. The sealing structure 490 may be formed to have a non-uniform thickness or a uniform thickness. For example, the sealing structure 490 may be disposed in the form of a gasket member made of rubber material.

According to an embodiment, since the sealing structure 1290 is divided into the sealed space in which the battery 1250 is disposed and the non-sealed space in which the battery 1250 is not disposed, occurrence of vibration can be reduced in the rear plate 1280 having the sealed space facing a portion of the conductive member 1270 and one face of the battery 1250. This is because the sealing structure 1290 blocks air flow, e.g., vibration. Reference numeral A2 may denote the location with which the sealing structure 1290 is capable of coming into close contact.

FIG. 13A illustrates a plan view of a rear plate on which a sealing structure according to various embodiments is formed. FIG. 13B illustrates a bottom view of a housing on which a conductive member according to various embodiments is disposed.

Referring to FIGS. 13A to 13B, an electronic device (e.g., the electronic device 100 illustrated in FIG. 1 or the electronic device 300 illustrated in FIG. 3) according to various embodiments may include a battery 1350 disposed in a housing 1310, a conductive member 1370, a rear plate 1380, and a sealing structure 1390.

According to an embodiment, the sealing structure 1390 may be formed on the rear plate 1380. For example, the sealing structure 1390 may be formed of a piece of double-sided tape using an adhesive material, a stepped structure of an injection-molded material, or a partition wall structure. According to an embodiment, the sealing structure 1390 may be disposed between a part of the battery 1350 and the conductive member 1370 and the rear plate 1380. The sealing structure 1390 may extend along the conductive member 1370 and an edge of the battery 1350.

According to an embodiment, the sealing structure 1390 may be formed while avoiding at least one coil (e.g., the coil 472 in FIG. 4A). When the front plate (e.g., the front plate 320 illustrated in FIG. 3) is viewed from above, the sealing structure 1390 may be disposed so as not to overlap the at least one coil (e.g., the coil 472 in FIG. 4A), or may be disposed in a shape that encloses at least one coil. The area in which the at least one coil (e.g., the coil 472 in FIG. 4A) is disposed may not overlap the sealing structure 1390.

The area sealed by the sealing structure 1390 may include a space sealed by one face of the battery 1350 and the rear plate 1380 and an area sealed by the peripheral area of the battery 1350 and the rear plate 1380. Compared with the space sealed by the sealing structure 1390 illustrated in FIGS. 12A and 12B, the peripheral area a3 of the battery 1350 is added to the area sealed by the sealing structure 1390.

According to an embodiment, the sealing structure 1390 may be disposed on the first face 1380a of the rear plate 1380 in a protruding shape having a thickness in the first direction (e.g., the first direction {circle around (1)} illustrated in FIG. 12C). The sealing structure 1390 may be formed to have a non-uniform thickness or a uniform thickness. For example, the sealing structure 1390 may be disposed in the form of a gasket member of made of a rubber material, may be formed as a stepped structure, or may be formed to have a thickness using an adhesive material.

According to an embodiment, with the sealing structure 1390, occurrence of vibration can be reduced in the rear plate 1380 facing an area al having the conductive member, an area a2 having the battery 1350, and an peripheral area a3 of the battery 1350. This is because the sealing structure 1390 blocks air flow, e.g., vibration. Reference numeral A3 may denote the location with which the sealing structure 1390 is capable of coming into close contact.

Although the present disclosure has been described with various embodiments, various changes and modifications may be suggested to one skilled in the art. It is intended that the present disclosure encompass such changes and modifications as fall within the scope of the appended claims.
