Detailed Description

(first embodiment)

< construction of electronic apparatus >

Fig. 1 is a perspective view showing an external appearance of an electronic device 1 according to a first embodiment of the present invention. The electronic device 1 is a portable multifunction information processing terminal such as a smartphone or a tablet computer. As shown in fig. 1, the electronic device 1 includes a housing 2, a display unit 3, a first antenna module 4A, a second antenna module 4B, a third antenna module 4C, and a fourth antenna module 4D. The housing 2 has a substantially rectangular parallelepiped shape, and has a front surface 2F, a back surface 2B, a left side surface 2L, a right side surface 2R, an upper surface 2U, and a lower surface 2D.

A display unit 3 for displaying an image is provided on the front surface 2F. A first antenna module 4A is provided in the vicinity of a portion on the upper surface 2U side in the left side surface 2L. A third antenna module 4C is provided in the vicinity of a portion on the lower surface 2D side of the left side surface 2L. A second antenna module 4B is provided in the vicinity of a portion on the upper surface 2U side in the right side surface 2R. A fourth antenna module 4D is provided in the vicinity of a portion on the lower surface 2D side in the right side surface 2R.

Thereby, the first to fourth antenna modules 4A to 4D can stabilize the communication processing relating to the communication with the external device located outside the electronic apparatus 1 and improve the communication function. Examples of the external device include a communication device provided in a base station.

The first to fourth antenna modules 4A to 4D are provided inside the housing 2 and are arranged separately from each other. This reduces heat transfer from one antenna module to another antenna module among the first antenna module 4A to the fourth antenna module 4D.

The first to fourth antenna modules 4A to 4D are components for performing communication such as wireless communication with an external device, and incorporate wireless-related components such as an antenna and a power amplifier. The antenna is preferably a means for accessing a 5G line, and more preferably a means capable of data communication using millimeter waves. The antenna may be a means for accessing a line capable of data communication, such as a 4G line. Each of the first antenna module 4A to the fourth antenna module 4D incorporates a power amplifier, and therefore, these antenna modules generate heat when communicating with an external device.

< Electrical constitution of electronic apparatus 1 >

Fig. 2 is a block diagram showing an electrical configuration of the electronic apparatus 1 shown in fig. 1. As shown in fig. 2, the electronic apparatus 1 includes a first temperature sensor 5A, a second temperature sensor 5B, a third temperature sensor 5C, a fourth temperature sensor 5D, a control device 6, and a storage device 7.

The first temperature sensor 5A is disposed in the vicinity of the first antenna module 4A, and measures the temperature of the first antenna module 4A. Similarly, the second to fourth temperature sensors 5B to 5D are provided in the vicinity of the second to fourth antenna modules 4B to 4D, respectively, and measure the temperatures of the second to fourth antenna modules 4B to 4D.

Further, the first temperature sensor 5A may be provided inside the first antenna module 4A. In this case, the first temperature sensor 5A may measure the temperature of a substrate on which a power amplifier built in the first antenna module 4A is mounted, or may measure the temperature of the power amplifier or its surroundings. The second to fourth temperature sensors 5B to 5D also have the same configuration as the first temperature sensor 5A.

The control device 6 comprehensively controls each component provided in the electronic apparatus 1, and includes, for example, a CPU (Central Processing Unit) and a GPU (Graphics Processing Unit). The number of the control devices 6 may be one or plural. The control device 6 includes an antenna control unit 61, a temperature acquisition unit 62, and a temperature determination unit 63. The storage device 7 is a nonvolatile memory hard disk such as a flash memory.

The antenna control section 61 controls each of the first to fourth antenna modules 4A to 4D. Specifically, the antenna control unit 61 functions as a transmission power adjustment processing unit that adjusts transmission power for each of the first antenna module 4A to the fourth antenna module 4D. The transmission power is a power output by each of the first to fourth antenna modules 4A to 4D when transmitting information to an external device in communication with the external device.

The temperature acquisition unit 62 acquires the temperature of each of the first antenna module 4A to the fourth antenna module 4D from the first temperature sensor 5A to the fourth temperature sensor 5D, respectively. The temperature determination section 63 determines whether the temperature of each of the first antenna module 4A to the fourth antenna module 4D acquired by the temperature acquisition section 62 reaches a predetermined threshold value. The antenna control unit 61 selects an antenna module having a temperature lower than a predetermined threshold value from the first to fourth antenna modules 4A to 4D.

< switching processing of antenna Module >

Fig. 3 is a flowchart showing the sequence of the switching process of the antenna module in the process of the electronic apparatus 1 shown in fig. 1. Here, the power of the electronic apparatus 1 is turned on. The temperature acquisition section 62 supplies the antenna control section 61 with the acquired temperature information of the temperature of each of the first to fourth antenna modules 4A to 4D. The antenna control section 61 refers to the temperature information supplied from the temperature acquisition section 62.

The antenna control unit 61 determines whether or not there is any antenna module having a temperature lower than a predetermined threshold value among the first to fourth antenna modules 4A to 4D (S1). The antenna control unit 61 determines that there is NO antenna module whose temperature has not reached the predetermined threshold (NO in S1), and continues the process of step S1.

On the other hand, the antenna control unit 61 determines that there is an antenna module whose temperature has not reached the predetermined threshold (YES in S1). In this case, the antenna control unit 61 selects one transmission antenna module from among antenna modules whose temperatures have not reached the predetermined threshold value (S2). The transmitting antenna module is an antenna module for transmitting information from the electronic apparatus 1 to an external device. For example, the antenna control section 61 selects the first antenna module 4A as the transmission antenna module.

The antenna control section 61 activates the first antenna module 4A selected as the transmitting antenna module. That is, the antenna control unit 61 increases the transmission power from 0 to a predetermined transmission power for the first antenna module 4A. The antenna control unit 61 increases the transmission power of the first antenna module 4A, thereby starting transmission of information from the first antenna module 4A, which is the selected transmission antenna module, to the external device (S3).

While the antenna control section 61 controls the first antenna module 4A, the temperature acquisition section 62 acquires the temperature of the first antenna module 4A measured by the first temperature sensor 5A from the first temperature sensor 5A. The temperature acquisition unit 62 supplies the antenna control unit 63 with temperature information indicating the acquired temperature of the first antenna module 4A.

The temperature determination unit 63 refers to the temperature information supplied from the temperature acquisition unit 62. The temperature determination unit 63 determines whether or not the temperature of the first antenna module 4A in the transmission information reaches a predetermined threshold (S4). When the temperature determination unit 63 determines that the temperature of the first antenna module 4A in the transmission information has not reached the predetermined threshold value (NO in S4), it continues the process of step S4.

On the other hand, when determining that the temperature of the first antenna module 4A in the transmission information has reached the predetermined threshold value (YES in S4), the temperature determination unit 63 supplies the antenna control unit 61 with temperature determination information indicating that the temperature of the first antenna module 4A has reached the predetermined threshold value. The antenna control unit 61 refers to the temperature determination information supplied from the temperature determination unit 63.

The antenna control unit 61 selects the next transmission antenna module for transmitting information from among the antenna modules whose temperatures have not reached the predetermined threshold value (S5). For example, the antenna control section 61 selects the second antenna module 4B as the next transmission antenna module.

In step S5, the antenna control unit 61 activates the second antenna module 4B selected as the transmitting antenna module. That is, the antenna control unit 61 increases the transmission power from 0 to a predetermined transmission power for the second antenna module 4B. The antenna control unit 61 increases the transmission power of the second antenna module 4B to start transmission of information from the second antenna module 4B to an external device.

The antenna control section 61 performs the process of step S5, and stops the first antenna module 4A. That is, the antenna control unit 61 decreases the transmission power of the first antenna module 4A from the predetermined transmission power to 0. In this way, the antenna control unit 61 performs transmission power adjustment processing for adjusting transmission power for the first antenna module 4A and the second antenna module 4B.

In step S5, the antenna control unit 61 may select an antenna module having increased transmission power from the plurality of antenna modules in a predetermined order in the transmission power adjustment process. The predetermined sequence is a sequence in which the first antenna module 4A to the fourth antenna module 4D are preferentially activated, and is stored in the storage device 7 in advance.

The predetermined order may be, for example, the order of the first antenna module 4A, the second antenna module 4B, the third antenna module 4C, and the fourth antenna module 4D. In this case, as in step S5, after the first antenna module 4A is activated, the antenna control unit 61 selects the second antenna module 4B having the higher priority order than the first antenna module 4A.

In this way, the antenna control section 61 selects an antenna module having increased transmission power from the plurality of antenna modules in a predetermined order. This can simplify the configuration of the antenna module for selecting the increase in transmission power, and thus can easily maintain the transmission power of the entire electronic device 1.

Further, in step S5, the antenna control unit 61 may randomly select an antenna module having increased transmission power from the plurality of antenna modules in the transmission power adjustment process. This can simplify the configuration of the antenna module for selecting the increase in transmission power, and thus can easily maintain the transmission power of the entire electronic device 1.

While controlling the second antenna module 4B in step S5, the antenna control unit 61 determines whether or not to stop selecting an antenna module (S6). When the antenna control unit 61 determines that the selection of the antenna module is to be stopped (YES in S6), the control device 6 ends the antenna module switching process. When determining that the selection of the antenna module is not to be stopped (NO in S6), the antenna control unit 61 returns to the process of step S3.

In step S6, whether the antenna control unit 61 stops the setting for selecting the antenna module, that is, whether the switching process of the antenna module is continuously set, may be set by the user operating the electronic apparatus 1. When the transmission of the information itself is stopped, the antenna control unit 61 simultaneously stops the selection of the antenna module, such as when the stop of the transmission of the information is instructed to the electronic device 1 from the communication device provided in the base station.

That is, when the user sets to continue the antenna module switching process in the electronic apparatus 1, the antenna control unit 61 determines in step S6 that the selection of the antenna module is not to be stopped. When the user sets to stop the antenna module switching process in the electronic device 1, the antenna control unit 61 determines in step S6 to stop selecting an antenna module.

< modification example >

The antenna control unit 61 may transmit information from a plurality of antenna modules to an external device. In this case, the antenna control unit 61 adjusts the transmission power of each antenna module as follows under the condition that the sum of the transmission power of each antenna module does not exceed the range specified by the standard specification.

In step S2, the antenna control unit 61 may select a plurality of transmission antenna modules from among antenna modules whose temperatures have not reached a predetermined threshold. In this case, in step S3, the antenna control unit 61 starts to transmit information from the selected plurality of transmission antenna modules to the external device.

Further, in step S4, the temperature determination unit 63 may determine whether or not the temperature of at least one of the plurality of antenna modules in the transmission information reaches a predetermined threshold value. When the temperature determination unit 63 determines in step S4 that the temperatures of the plurality of antenna modules have reached the predetermined threshold, the antenna control unit 61 may select a plurality of next transmission antenna modules in step S5.

In this case, in step S5, the antenna control section 61 activates the selected plurality of antenna modules as the transmission antenna modules. That is, the antenna control unit 61 increases the transmission power from 0 to a predetermined transmission power for the plurality of antenna modules. The antenna control unit 61 may increase the transmission power from the first transmission power to the second transmission power for the plurality of antenna modules. The first transmission power is a power lower than the second transmission power and not 0.

In addition, the antenna control unit 61 stops the plurality of antenna modules which have been determined in step S4 that the temperature of the antenna module has reached the predetermined threshold value. That is, the antenna control unit 61 reduces the transmission power from the predetermined transmission power to 0 for the plurality of antenna modules. The antenna control unit 61 may reduce the transmission power from the second transmission power to the first transmission power for the plurality of antenna modules.

As described above, the antenna control unit 61 performs the following transmission power adjustment processing. Specifically, the antenna control unit 61 causes at least one of the plurality of antenna modules to reduce the transmission power in accordance with the temperature of each of the plurality of antenna modules measured by each of the temperature sensors. In addition, the antenna control unit 61 increases the transmission power for at least one antenna module out of the plurality of antenna modules other than the antenna module that decreases the transmission power.

Thus, when the temperature of a certain antenna module becomes high, the temperature sensor measures the temperature rise, and the transmission power of the antenna module is reduced. This can prevent a part of the electronic apparatus 1 from being locally heated and giving a user a sense of discomfort. In addition, since the transmission power of the antenna module other than the antenna module having the reduced transmission power is increased, the transmission power of the entire electronic device 1 can be maintained.

In the electronic apparatus 1, switching processing of a plurality of antenna modules provided to improve the communication function of the electronic apparatus 1 is performed, thereby suppressing a user from feeling uncomfortable due to a local heating of a part of the electronic apparatus 1. Therefore, it is not necessary to newly provide a structure for suppressing the discomfort given to the user in the electronic apparatus 1, and a new space is not necessary. In addition, the user can be prevented from feeling uncomfortable without changing the structure in which the plurality of antenna modules are provided. Therefore, the communication function of the electronic apparatus 1 can be improved smoothly by the plurality of antenna modules.

(second embodiment)

The following describes a first embodiment of the present invention. For convenience of explanation, members having the same functions as those described in the first embodiment are given the same reference numerals, and the explanation thereof will not be repeated. Fig. 4 is a block diagram showing an electrical configuration of an electronic device 1A according to a second embodiment of the present invention.

As shown in fig. 4, the electronic device 1A is different from the electronic device 1 in that the control device 6 is changed to a control device 6A and that the grip sensor 8 and the gravity sensor 9 are provided. The control device 6A is different from the control device 6 in that it includes a grip information acquiring unit 64 and a gravity direction acquiring unit 65.

The grip sensor 8 detects that the user holds the electronic apparatus 1A. The grip sensor 8 is provided on at least one of the left side surface 2L and the right side surface 2R of the housing 2. The grip sensor 8 is, for example, an electrostatic capacitance type sensor or a pressure-sensitive type sensor. The grip sensor 8 may be one or a plurality of sensors. The gravity sensor 9 detects the direction of gravity. The gravity sensor 9 is provided inside the housing 2. The gravity sensor 9 may be one or more.

The grip information acquiring unit 64 acquires grip information indicating that the user grips the electronic apparatus 1A from the grip sensor 8. The gravity direction acquisition unit 65 acquires gravity information indicating the gravity direction from the gravity sensor 9.

In step S5, the antenna control unit 61 reduces the frequency of selecting an antenna module for increasing the transmission power, as compared with antenna modules other than the antenna module, in the transmission power adjustment process, the antenna module existing near the position where the grip sensor 8 detects the grip of the electronic device 1A by the user.

This configuration is based on the premise that the antenna control unit 61 selects antenna modules in a predetermined order or randomly selects antenna modules in step S5. For example, consider a case where the second antenna module 4B is an antenna module that detects the presence near the position where the user holds the electronic apparatus 1A.

In this case, in step S5, the antenna control unit 61 selects antenna modules in a predetermined order or randomly selects antenna modules so that the frequency with which the second antenna module 4B is selected is lower than that of other antenna modules.

The grip sensor 8 is provided with regions corresponding to the first antenna module 4A to the fourth antenna module 4D, respectively. The region corresponding to the second antenna module 4B in the grip sensor 8 is set in the vicinity of the second antenna module 4B. For example, consider a case where a grip by the user is detected in the region corresponding to the second antenna module 4B in the grip sensor 8. In this case, the grip information acquiring section 64 acquires, as the grip information, information that the antenna module existing near the position where the grip of the electronic apparatus 1A by the user is detected is the second antenna module 4B.

The grip information acquired by the grip information acquiring unit 64 is supplied to the antenna control unit 61, and the antenna control unit 61 reduces the frequency of selecting the second antenna module 4B compared to other antenna modules in step S5. That is, the antenna control unit 61 reduces the frequency of selecting an antenna module for which the user's grip is detected in the corresponding area of the grip sensor 8, as compared with antenna modules other than the antenna module.

In the electronic apparatus 1A, the position touched by the hand of the user is higher in temperature than other positions in the electronic apparatus 1A. Therefore, it is preferable to reduce the frequency of selecting an antenna module that is present near the position where the grip sensor 8 detects the grip of the electronic device 1A by the user, as an antenna module for increasing the transmission power. This can suppress a situation in which a part of the electronic apparatus 1 is locally heated and gives a user a sense of discomfort. In addition, the electronic apparatus 1A can be effectively prevented from overheating as a whole.

In step S5, the antenna control unit 61 reduces the frequency of selecting an antenna module for increasing the transmission power in the transmission power adjustment process, as compared with antenna modules other than the antenna module, for the antenna module determined to be present vertically below the electronic device 1A based on the direction of gravity detected by the gravity sensor 9.

The following specifically explains the process. For example, the first antenna module 4A to the fourth antenna module 4D are each set with an angular range of the azimuth angle and an angular range of the pitch angle. The azimuth angle is an angle formed with a predetermined direction on a plane orthogonal to a direction from the center of the electronic device 1A toward the upper surface 2U, and the pitch angle is an angle in the up-down direction with respect to a plane orthogonal to a direction from the center of the electronic device 1A toward the upper surface 2U. The gravity direction acquisition unit 65 determines that an antenna module including the gravity direction in the angle range of the corresponding azimuth angle and the angle range of the corresponding pitch angle is a vertically downward antenna module.

A portion vertically below the electronic apparatus 1A is more likely to be touched by the hand of the user than other portions of the electronic apparatus 1A. Therefore, it is preferable to reduce the frequency of selecting an antenna module that is determined to be present vertically below the electronic device 1A based on the direction of gravity detected by the gravity sensor 9 as an antenna module whose transmission power is increased. This can suppress a situation in which a part of the electronic apparatus 1 is locally heated and gives a user a sense of discomfort. In addition, the electronic apparatus 1A can be effectively prevented from overheating as a whole.

The electronic device 1A may be provided with only one of the grip sensor 8 and the gravity sensor 9. In this case, the control device 6A includes only one of the grip information acquiring unit 64 and the gravitational direction acquiring unit 65.

As described above, the antenna control unit 61 in step S5 selects the next transmission antenna module by (1) selecting the next transmission antenna module in a predetermined order; (2) a method of random selection; (3) a method based on a grip sensor 8; and (4) gravity sensor 9 based methods. The antenna control section 61 may automatically change the four methods, and the four methods may also be changed by the user operating the electronic apparatus 1.

[ implementation by software ]

The control blocks (particularly, the antenna control unit 61, the temperature acquisition unit 62, the temperature determination unit 63, the grip information acquisition unit 64, and the gravity direction acquisition unit 65) of the control devices 6 and 6A may be implemented by a logic circuit (hardware) formed in an integrated circuit (IC chip) or the like, or may be implemented by software.

In the latter case, the control devices 6 and 6A include a computer, and software for realizing the respective functions, that is, commands for executing programs. The computer includes, for example, at least one processor (control device) and at least one computer-readable storage medium for storing the program. Then, in the computer, the processor reads the program from the storage medium and executes the program, thereby achieving the object of the present invention. As the processor, for example, a CPU can be used. As the storage medium, a "non-transitory tangible medium" such as a magnetic tape, a magnetic disk, a card, a semiconductor Memory, a programmable logic circuit, or the like can be used in addition to a ROM (Read Only Memory) or the like. Further, a RAM (Random Access Memory) or the like may be provided to expand the program. Further, the above-described program may be supplied to the computer via an arbitrary transmission medium (a communication network, a broadcast wave, or the like) capable of transmitting the program. An aspect of the present invention can also be implemented in the form of a data signal embedded in a carrier wave, the program being embodied by electronic transmission.
