Japanese Patent Application Laid-Open No. 2021-12505

Portable information processing devices are required to be smaller and thinner. In addition, portable information processing devices are required to support high-speed communication and various communication systems. In order to realize high-speed and diverse communications, portable information processing devices are often provided with multiple antennas such as WLAN, WWAN, and MIMO. In order to reduce the size and thickness of the housing while providing a plurality of antennas in this way, it is conceivable to arrange antennas for wireless communication in both the first housing and the second housing. .

By the way, when communication antennas are arranged in both the first housing and the second housing, when the housings are closed, the antennas arranged in the first housing and the second housing are separated from each other. and each antenna arranged in . Here, in a portable information processing device that performs communication even when the housing is closed, such as having a modern standby function, an antenna arranged in the first housing and an antenna arranged in the second housing interfering with each other, it is easy to cause deterioration of communication accuracy.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a portable information processing apparatus capable of suppressing deterioration in communication accuracy when the housing is closed.

To solve the above problems, a portable information processing apparatus according to an aspect of the present invention includes a first housing and a second housing rotatably connected to the first housing by a hinge mechanism. a first main antenna and a first sub-antenna housed in the first housing; and a second main antenna and a second sub-antenna housed in the second housing; is closed with respect to the first housing, the second main antenna is arranged in the direction in which the first housing and the second housing face each other. does not overlap with any of

According to the above aspect of the present invention, when the housing is in the closed state, interference between the second main antenna and the first main antenna and the first sub-antenna is suppressed, thereby improving the communication accuracy of the portable information processing device. Decrease can be suppressed.

Here, the first main antenna and the first sub-antenna may support MIMO, and the second main antenna and the second sub-antenna may support WLAN communication standards.

In this case, since the MIMO antenna is mounted, the communication speed of the portable information processing device can be improved. In addition, when the housing is in the closed state, it is possible to protect the WLAN MAIN antenna, which is highly susceptible to interference between antennas, from the interference, thereby effectively suppressing deterioration in communication accuracy. .

The first housing includes a first speaker, a first speaker driver that drives the first speaker, a second speaker, and a second speaker driver that drives the second speaker. , wherein the second housing further houses a third main antenna and a third subantenna, and when the second housing is closed with respect to the first housing, the third main antenna The antenna may overlap neither the first speaker driver nor the second speaker driver in the direction in which the first housing and the second housing face each other.

In this case, when the housing is in the closed state, radio waves transmitted and received from the third main antenna are less likely to be shielded by the speaker driver having a conductive material, and deterioration in communication accuracy can be further suppressed.

Also, the third main antenna and the third sub-antenna may correspond to the WWAN communication standard.

In this case, the portable information processing device can be directly connected to the Internet without LAN communication or the like. Also, when the housing is in the closed state, the MAIN antenna for WWAN, which is highly susceptible to shielding of radio waves, can be protected from the shielding, and deterioration of communication accuracy can be more effectively suppressed. .

Further, the hinge mechanism is fixed to a first facing surface of the first housing that faces the second housing when the second housing is closed with respect to the first housing. and a first free end located on the side opposite to the first connection end, wherein the second housing of the second housing is connected to the first housing. A second facing surface, which is a surface facing the first housing when closed with respect to the body, includes a second connecting end to which the hinge mechanism is fixed, and a side opposite to the second connecting end. and a second free end positioned at the first main antenna, the first sub-antenna, the first speaker driver, and the second speaker driver in the vicinity of the first free end. The second main antenna, the second sub-antenna, the third main antenna, and the third sub-antenna are arranged along the first free end, and the second main antenna, the second sub-antenna, the third main antenna, and the third sub-antenna are arranged along the first free end. It may be arranged along two free ends.

In this case, since each antenna and each speaker driver can be integrated at the end of the housing, it becomes easier to realize thinning and miniaturization of the housing.

The first speaker driver, the first sub-antenna, the first main antenna, and the second speaker driver are arranged in this order near the first free end, and the second main antenna, The third sub-antenna, the second sub-antenna and the third main antenna may be arranged in this order near the second free end.

In this case, since the second main antenna and the third main antenna are arranged outside in the left-right direction, it is possible to reduce the difficulty of tuning the second main antenna and the third main antenna. In addition, since the first speaker and the second speaker are arranged symmetrically, it is possible to provide the user with a comfortable acoustic experience.

According to the above aspect of the present invention, it is possible to provide a portable information processing apparatus capable of suppressing deterioration in communication accuracy when the housing is in the closed state.

In this embodiment, the first housing 10 has a flat box shape. The first connecting end portion 10a and the first free end portion 10b of the first housing 10 extend along the left-right direction X.

At least part of the palm rest 11 is provided with a first transmissive portion 11a. In the present embodiment, two first transmitting portions 11a are provided, each located near the first free end portion 10b. The material of the first transmission part 11a is preferably a non-conductive substance such as resin.

Similarly, the first speaker driver 42A and the second speaker driver 42B may be collectively referred to simply as the speaker driver 42 in some cases. The speaker driver 42 is an element that converts an electrical signal into sound (vibration) and vibrates the speaker box 41 to drive the speaker 40 . In this embodiment, the material of the speaker box 41 is a non-conductive substance such as resin or wood, and the speaker driver 42 contains a conductive substance such as metal.

In this embodiment, the second housing 20 has a flat box shape. The second housing 20 is also called a display housing. A second connecting end portion 20a and a second free end portion 20b of the second housing 20 extend along the left-right direction X. As shown in FIG. A display 22 and a bezel 21 surrounding the display 22 are provided on the second facing surface 20 c of the second housing 20 . Examples of the material of the bezel 21 include metal. As the display 22, for example, an OLED (Organic Light Emitting Diode), a liquid crystal display, or the like can be used. Note that the portable information processing device 1 does not have to include the display 22 .

At least part of the bezel 21 is provided with a second transmissive portion 21a. In the present embodiment, two second transmitting portions 21a are provided, each located near the second free end portion 20b. The material of the second transmitting portion 21a is preferably a non-conductive substance such as resin. The second transmitting portion 21a can be formed, for example, by performing two-color molding (also referred to as insert molding or hybrid molding) on the bezel 21 made of metal. The second transmitting portion 21a is a portion that transmits radio waves transmitted and received by a second antenna 32 and a third antenna 33, which will be described later.

The second antenna 32 is an antenna for wireless communication of the portable information processing device 1 . Among the second antennas 32, the second main antenna 32A is the MAIN antenna and the second sub-antenna 32B is the AUX antenna. The second antenna supports a communication scheme different from that of the first antenna 31 . For example, the communication standard supported by the second antenna 32 is WLAN (Wireless Local Area Network).

Among the third antennas 33, the third main antenna 33A is the MAIN antenna and the third sub-antenna 33B is the AUX antenna. A third antenna 33 supports a communication scheme different from that of the first antenna 31 and the second antenna 32 . For example, the communication standard supported by the third antenna 33 is WWAN (Wireless Wide Area Network).

The second antenna 32 and the third antenna 33 of the present embodiment are arranged so as to be included in the second transmitting portion 21a when viewed from the direction perpendicular to the second facing surface 20c. As a result, the radio waves transmitted and received by the second antenna 32 and the third antenna 33 are less likely to be shielded by the conductive material such as the bezel 21 . Note that the second antenna 32 and the third antenna 33 may not be included in the second transmitting portion 21a when viewed from the facing direction Z, and the second transmitting portion 21a may be omitted.

Next, the operation of the portable information processing apparatus 1 configured as described above will be described.

Generally, it is known that when an antenna is close to another antenna, the antenna and the other antenna interfere with each other, causing deterioration in communication accuracy of the antenna. Further, it is known that when an antenna is close to another conductive material, radio waves transmitted and received from the antenna are shielded by the conductive material, causing deterioration in communication accuracy of the antenna. As a result of intensive studies by the inventors of the present application, among the antennas for MIMO, WLAN, and WWAN, the MAIN antenna for WLAN has the lowest communication accuracy when the above interference or shielding occurs. Then it turned out to be the MAIN antenna for WWAN.

Therefore, in the portable information processing apparatus 1 of this embodiment, the first to third antennas 31 to 33 and the speaker 40 are arranged as shown in FIG. 1, for example. This arrangement positions the right end of the second main antenna 32A to the left of the left end of the first sub-antenna 31B. Therefore, when the housing C is closed, the second main antenna 32A does not overlap the first sub-antenna 31B (and the first main antenna 31A) when viewed from the facing direction Z. This prevents the second main antenna 32A and the first antenna 31 from interfering with each other and lowering the communication accuracy of the portable information processing device 1 when the housing C is closed. In particular, when the second antenna 32 is a WLAN antenna, deterioration of communication accuracy can be suppressed more effectively.

As shown in FIG. 2, when the housing C is closed, the third main antenna 33A is configured such that the radially outer end (front end) of the second speaker driver 42B is positioned at the third main antenna 33A. It is arranged so as to be located radially inward (rearward) from the radially inner end (rear end). Therefore, when the housing C is closed, the third main antenna 33A does not overlap the second speaker driver 42B (and the first speaker driver 42A) when viewed from the opposing direction Z. As a result, when the housing C is closed, radio waves transmitted and received from the third main antenna 33A are blocked by the speaker driver 42 containing a conductive material, and the communication accuracy of the portable information processing apparatus 1 is lowered. is suppressed. In particular, when the third antenna 33 is a WWAN antenna, deterioration of communication accuracy can be suppressed more effectively. Also, as shown in FIG. 3, the second main antenna 32A does not overlap the speaker driver 42 either. As a result, deterioration in communication accuracy of the portable information processing device 1 is further suppressed. In particular, when the second antenna 32 is a WLAN antenna, deterioration of communication accuracy can be suppressed more effectively.

Further, since the first antenna 31 and the speaker 40 are provided in the vicinity of the first free end portion 10b, the first antenna 31 and the speaker 40 are less likely to structurally interfere with a mother board, a battery, and the like (not shown). . This makes it easier to reduce the dimension of the first housing 10 in the facing direction Z. As shown in FIG. Further, since the second and third antennas 32 and 33 are provided near the second free end portion 20b, the second and third antennas 32 and 33 are provided outside the display 22 in the horizontal direction X, for example. Enlargement of the bezel 21 can be suppressed as compared with the case where the bezel 21 is provided. Further, since the second and third antennas 32 and 33 are provided in the vicinity of the second free end portion 20b, the second and third antennas 32 and 33 interfere structurally with a display substrate (not shown) or the like. difficult to do. This makes it easier to reduce the thickness of the second housing 20 (the dimension in the direction perpendicular to the second facing surface 20c). That is, by providing the first to third antennas 31 to 33 and the speaker 40 near the first free end portion 10b or the second free end portion 20b, the housing C can be made smaller and thinner.

Furthermore, in the example of FIG. 1, the second main antenna 32A and the third main antenna 33A are arranged outside in the horizontal direction X. As shown in FIG. By the way, when using an antenna, it is generally necessary to perform tuning work for impedance matching between the antenna and a communication device substrate (for example, a mother board). As a result of intensive studies by the inventors of the present application, it was found that the tuning work for the WWAN MAIN antenna and the WLAN MAIN antenna is more difficult than the tuning work for other antennas. On the other hand, especially when the second main antenna 32A is used as the main antenna for WLAN and the third main antenna 33A is used as the main antenna for WWAN, the two antennas, which are relatively difficult to tune, can be replaced by other antennas. move away from Thereby, the impedance of the two antennas can be stabilized, and the difficulty of tuning can be reduced. Also, in the example of FIG. 1, the first speaker 40A and the second speaker 40B are arranged symmetrically in the horizontal direction X. As shown in FIG. As a result, so-called surround sound expression becomes possible, and a comfortable acoustic experience can be provided to the user.

As described above, the portable information processing apparatus 1 of this embodiment includes the first housing 10 and the second housing 20 rotatably connected to the first housing 10 by the hinge mechanism H. , a first main antenna 31A and a first subantenna 31B housed in the first housing 10, and a second main antenna 32A and a second subantenna 32B housed in the second housing 20; When C is closed, the second main antenna 32A overlaps both the first main antenna 31A and the first subantenna 31B in the facing direction Z in which the first housing 10 and the second housing 20 face each other. not.

With this configuration, when the housing C is closed, interference between the second main antenna 32A and the first antenna 31 is suppressed, and deterioration in communication accuracy of the portable information processing device 1 can be suppressed.

Also, the first main antenna 31A and the first sub-antenna 31B support MIMO, and the second main antenna 32A and the second sub-antenna 32B support the WLAN communication standard. With this configuration, the communication speed of the portable information processing device 1 can be improved. In addition, when the housing C is in the closed state, it is possible to protect the main antenna for WLAN, which is highly susceptible to interference between antennas, from the interference, thereby effectively suppressing deterioration in communication accuracy. can.

With this configuration, when the housing C is in the closed state, radio waves transmitted and received from the third main antenna 33A are less likely to be shielded by the speaker driver 42 having a conductive material, thereby further suppressing deterioration in communication accuracy. can be done.

Also, the third main antenna 33A and the third sub-antenna 33B comply with the WWAN communication standard. With this configuration, the portable information processing apparatus 1 can be directly connected to the Internet without LAN communication or the like. In addition, when the housing C is in the closed state, the WWAN antenna, which is highly susceptible to shielding of radio waves, can be protected from the shielding, and deterioration of communication accuracy can be suppressed more effectively.
