Description

  The present invention relates to a mobile phone, and more particularly to an improvement of a mobile phone provided with a planar antenna.

  In recent years, there are concerns about the effects of electromagnetic waves on the human body. The influence of electromagnetic waves is evaluated using, for example, a specific absorption rate (SAR) indicating the amount of energy absorbed when the human head is exposed to electromagnetic waves. Since the mobile phone is used by placing the receiver on the user's ear during a call, the SAR on the user's head can be reduced by disposing the antenna at a position far from the receiver.

  In the past, mobile phones were generally equipped with whip antennas that were pulled out from the upper part of the housing and used, but now mobile phones with flat antennas that can be easily reduced in size and weight have become common. . For example, in the case of a mobile phone generally called a smartphone, the mobile phone includes a thin casing having a substantially rectangular front surface and a flat antenna.

  Such a smartphone generally has a configuration in which the receiver is arranged at the upper part of the casing and the planar antenna is arranged at the lower part of the casing. By adopting such a configuration, the planar antenna can be arranged at a position far from the receiver, and the SAR of the head can be reduced. However, since the user who is talking is holding the lower part of the casing, the planar antenna arranged at the lower part of the casing is covered by the user's hand, and there is a problem in that the radiation performance is degraded.

  Patent Document 1 describes a mobile phone in which a movable part with a built-in antenna is provided at the top of a housing. This mobile phone is a slide-type mobile phone capable of sliding a pair of housings, and is configured such that the movable portion is inclined toward the back side of the housing by a slide operation for expanding the housing. For this reason, the antenna is moved away from the human body and the metal slide mechanism, so that the radiation efficiency of the antenna is improved and the SAR with respect to the human head is reduced.

JP 2009-49583 A

  In the mobile phone described in Patent Document 1, the mobile phone is slid and unfolded during a call, and the receiver is disposed at the top of the housing, whereas the antenna is disposed near the center of the housing and is more than the receiver. Located in a low position. For this reason, there was a problem that the radiation performance of the antenna deteriorated by being covered by the user's hand during a call.

  In addition, the mobile phone of Patent Document 1 has a problem that since the movable part is moved by a slide operation, the antenna can be slightly tilted, and the SAR cannot be sufficiently reduced. In addition, there is a problem that the metal slide mechanism reduces the radiation efficiency of the antenna.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a mobile phone capable of reducing the SAR in the user's head and improving the radiation performance of the antenna. It is another object of the present invention to provide a mobile phone that can open and close the movable part without complicating the user operation when making a call, answering an incoming call, or ending a call.

  A mobile phone according to a first aspect of the present invention includes a thin casing in which a call receiver is formed near the upper end of a front surface having a substantially rectangular shape, and a facing surface facing the upper end surface of the thin casing. A movable part connected to the body so as to be openable and closable, and a planar antenna disposed on the opposite surface for transmitting and receiving a call signal, and by opening the movable part, in the vicinity of the call receiver, The movable part protrudes rearward from the thin casing and is configured such that the facing surface faces upward.

  According to such a configuration, in a state where the movable portion is opened, the movable portion on which the planar antenna is formed can be protruded rearward of the thin casing, and the planar antenna can be moved away from the human head and the thin casing. For this reason, while reducing SAR in a human head, the radiation | emission characteristic of a planar antenna can be improved. Moreover, since the upper side of the planar antenna is open, the radiation characteristics of the planar antenna can be further improved. Furthermore, since the planar antenna is disposed in the vicinity of the call receiver, the planar antenna is not covered with the user's hand and the radiation performance is not deteriorated. On the other hand, in a state where the movable part is closed, the planar antenna faces the upper end surface of the thin casing, so that the planar antenna can be protected while having a shape suitable for carrying and storage.

  In addition to the above configuration, the mobile phone according to the second aspect of the present invention designates an opening / closing state detecting means for detecting an opening / closing state of the movable part and a destination based on an opening operation of the movable part in a standby state The destination designation means for displaying the destination designation screen and the incoming call response means for generating the incoming response signal based on the opening operation of the movable part during the incoming call.

  According to such a configuration, since the destination designation screen is displayed based on the opening operation of the movable part in the standby state where the incoming call is not performed, the opening operation of the movable part and the destination designation screen are displayed. It is not necessary to perform the operation of displaying the. Further, if the incoming call is in progress, an incoming call response signal is generated based on the opening operation of the movable part, and there is no need to separately perform the opening operation of the movable part and the incoming call response operation. Therefore, the movable part can be opened without complicating the user operation at the time of both outgoing and incoming calls.

  In addition to the above configuration, a mobile phone according to a third aspect of the present invention includes call termination means for terminating the call based on a closing operation for closing the movable part during a call.

  According to such a configuration, since the call can be ended by performing the closing operation of the movable portion, it is not necessary to separately perform the closing operation of the movable portion and the call end operation, and the user at the end of the call The movable part can be closed without complicating the operation.

  In a mobile phone according to a fourth aspect of the present invention, the movable part is a thin plate-like body. With such a configuration, a thin casing can be realized without increasing the size.

  According to the present invention, the movable part connected to the thin casing so as to be openable and closable has the facing surface facing the upper end surface of the thin casing, and the planar antenna is formed on the facing surface. And the movable part protrudes to the back of a thin housing | casing by opening operation of a movable part. For this reason, while reducing SAR in a human head, the radiation | emission characteristic of a planar antenna can be improved. On the other hand, when the movable part is closed, the planar antenna faces the upper end surface of the thin casing, so that the planar antenna can be protected while being shaped to be carried and stored.

  In addition to this, in a state where the movable portion is open, the facing surface is directed upward, and the upper portion of the planar antenna is open. For this reason, the radiation characteristics of the planar antenna can be further improved. Further, since the planar antenna is disposed in the vicinity of the call receiver, the planar antenna is not covered with the user's hand, and the radiation characteristics are not deteriorated. Therefore, extremely good radiation characteristics can be obtained with the movable part opened.

  According to the present invention, in the standby state, a destination designation screen is displayed based on the opening operation of the movable portion, and an incoming call response signal is generated based on the opening operation of the movable portion during an incoming call. The For this reason, the movable part can be opened without complicating the user operation at the time of both outgoing and incoming calls.

  Moreover, according to this invention, the said call can be terminated based on closing operation of the movable part during a call. For this reason, the movable portion can be closed without complicating the user operation at the end of the call.

The example of the destination list display screen displayed on LCD12a of the mobile telephone in Embodiment 2 of this invention is shown.

Embodiment 1 FIG.
FIG. 1 is an external view showing a configuration example of a mobile phone 1 according to Embodiment 1 of the present invention. In the mobile phone 1, a call receiver 11, a touch panel 12, an operation key 13, and a call microphone 14 are disposed on the front surface of the housing 10, and a flap 15 is disposed on the upper end surface of the housing 10 via a hinge portion 16. It is attached so that it can be opened and closed.

  The housing 10 has a thin shape whose front surface is a substantially rectangular plane. Here, a case where the front surface is a substantially rectangular plate-shaped body will be described, but a part or all of each surface of the housing 10 may be formed of a curved surface.

  The call receiver 11 is an audio output means for making a call with the user holding his / her ear, and is disposed near the upper end of the front surface of the housing 10. The call receiver 11 outputs a received sound based on a call signal received from a cellular base station (not shown) during a call. The touch panel 12 displays an image on the display screen and detects a touch operation on the display screen. For example, the position on the display screen where the user operation is performed is detected by detecting a change in capacitance on the display screen. The touch panel 12 occupies most of the front surface of the housing 10, and the call receiver 11 is disposed above the touch panel 12.

  The operation key 13 is a key for the user to display a menu screen or the like. The call microphone 14 is a voice input means for inputting a transmission sound, and is disposed near the lower end of the front surface of the housing 10. That is, the call receiver 11 and the call microphone 14 are arranged on opposite sides of the touch panel 12.

  The flap 15 is a movable part that can be opened and closed and is arranged to face the upper end surface of the housing 10. The flap 15 has a rear end connected to the back side of the upper end surface of the housing 10 via a hinge portion 16. For this reason, the user can open and close the flap 15 easily with a finger.

  FIG. 2 is a diagram illustrating a state where the user is holding the mobile phone 1 during a call. The portable telephone 1 is used with the flap 15 closed as shown in FIG. 1 when being carried or stored, and with the flap 15 opened as shown in FIG. 2 during a call.

  FIG. 3 is a diagram showing an example of the open / closed state of the flap 15, and shows the left side surface of the mobile phone 1 of FIG. FIG. 3A shows a state where the flap 15 corresponding to FIG. 1 is closed, and FIG. 3B shows a state where the flap 15 corresponding to FIG. 2 is opened.

  If the user performs an opening operation of the flap 15 in the state of FIG. 3A, the flap 15 rotates about 180 ° around the hinge portion 16, and the state of FIG. 3B is obtained. In the state of FIG. 3B, if the user performs the closing operation of the flap 15, the flap 15 can be rotated in the reverse direction to return to the state of FIG. The opening and closing operations of the flap 15 are performed by pressing and rotating the flap 15 with the user's finger.

  The flap 15 has a facing surface 15A that faces the upper end surface 10A of the housing 10, and the facing surface 15A has substantially the same shape as the upper end surface 10A. For this reason, as shown in FIGS. 1 and 3A, the upper end surface 10 </ b> A of the housing 10 is covered with the flap 15 in a state in which the flap 15 is closed. At this time, the mobile phone 1 has a shape in which the casing 10 is extended upward by the height of the flap 15. That is, the flap 15 does not have a portion that protrudes significantly from the housing 10, is compact when being carried or stored, and is not easily caught around, and is easy to handle. Note that it is desirable that the thickness of the flap 15 in the vertical direction is small. Here, the flap 15 is a plate-like body thinner than the depth of the housing 10.

  On the other hand, as shown in FIGS. 2 and 3 (b), when the flap 15 is opened, the flap 15 protrudes rearward from the casing 10, and the flap 15 is turned upside down. Both the upper end surface 10A and the facing surface 15A of the flap 15 face upward and the upper portion is open. An open / close detection sensor 18 is disposed on the upper end surface 10 </ b> A of the housing 10, and a planar antenna 17 is disposed on the facing surface 15 </ b> A of the flap 15.

  The planar antenna 17 is a flat antenna supported by the flap 15 and transmits and receives radio signals to and from a cellular base station as an antenna for cellular communication. For example, a flexible substrate on which a predetermined conductive pattern is formed can be used. In the drawing, such a flexible substrate is fixed to the facing surface 15A of the flap 15, and one end of the flexible substrate extends along the hinge portion 16 to the upper end surface 10A of the housing 10, and further communication in the housing 10 is performed. It is connected to a control circuit (not shown). For this reason, the planar antenna 17 can be used regardless of the open / closed state of the flap 15.

  The open / close detection sensor 18 is an open / closed state detection means for detecting the open / closed state of the flap 15, and outputs a detection signal corresponding to the open / closed state of the flap 15.

  The mobile phone 1 can project the flap 15 to the rear of the housing 10 by performing an opening operation of the flap 15. For this reason, compared with the case where the flap 15 is closed, the planar antenna 17 can be moved away from the call receiver 11. Therefore, it is possible to reduce the SAR in the human head during a call and improve the radiation characteristics of the planar antenna 17.

  In the state where the flap 15 is open, the planar antenna 17 is directed upward and the upper portion thereof is opened. For this reason, compared with the case where the flap 15 is closed, the radiation characteristic of the planar antenna 17 can be improved.

  In addition, the planar antenna 17 is disposed in the vicinity of the call receiver 11 with the flap 15 being open. In general, a user who is making a call with his / her ear placed on the call receiver 11 holds the mobile phone 1 so that his / her hand is lower than his / her ear. That is, in the case of the mobile phone 1, as shown in FIG. 2, the lower part of the housing 10, particularly the lower part than the call receiver 11 is gripped. For this reason, the planar antenna 17 during a call is difficult to be covered with the user's hand, and it is possible to prevent the radiation characteristics from deteriorating.

  Furthermore, in the state where the flap 15 is closed, the protruding portion from the housing 10 is reduced compared to the opened state. For this reason, it becomes a shape suitable for carrying and storage by closing the flap 15. Further, in the state where the flap 15 is closed, the planar antenna 17 faces the upper end surface 10A of the housing 10, so that the planar antenna 17 can be prevented from being damaged by an external force.

  The planar antenna 17 has a lower radiation characteristic when the flap 15 is closed than when the flat antenna 17 is opened. Even in this state, it is possible to perform cellular communication, but since the distance between the planar antenna 17 and the call receiver 11 is short and the head SAR increases, it is not desirable to use it for a call. However, such a problem does not occur if the data communication does not bring the ear close to the call receiver 11. In addition, during data communication, the radiation performance of the planar antenna 17 does not deteriorate due to the influence of the human head, so that better radiation characteristics can be obtained than during a call.

  FIG. 4 is a block diagram showing an example of the internal configuration of the mobile phone 1 in FIG. 1, and shows the main hardware configuration of the mobile phone 1. The cellular phone 1 includes a main control unit 21, a planar antenna 17, a communication control unit 22, an open / close detection sensor 18, a display control unit 23, a touch panel 12, an operation input unit 24, operation keys 13, a voice control unit 25, and a call receiver. 11 and a microphone 14 for calling. The touch panel 12 includes an LCD 12a having a display screen and a touch sensor 12b that detects a touch operation on the display screen.

  The main control unit 21 is a processor that controls main operations of the mobile phone 1. The communication control unit 22 transmits / receives a radio signal including a call signal to / from the cellular base station via the planar antenna 17. The display control unit 23 performs display control of the LCD 12a.

  The operation input unit 24 monitors user operations on the touch sensor 12 b and the operation keys 13, and outputs an operation input signal to the main control unit 21 if there is a user operation. The voice control unit 25 controls the call receiver 11 and the call microphone 14 to input and output call sounds.

  The open / close detection sensor 18 monitors the open / closed state of the flap 15 and outputs a detection signal indicating the open / closed state of the flap to the main control unit 21.

  FIG. 5 is a block diagram showing an example of the functional configuration of the main part of the mobile phone 1 of FIG. The cellular phone 1 includes an open / close detection sensor 18, a destination designation unit 31, a display control unit 23, a storage unit 32, an LCD 12 a, a communication control unit 22, and a planar antenna 17.

  The destination designation unit 31 generates a control signal for displaying a destination designation screen based on the detection signal of the open / close detection sensor 18. Based on the control signal of the destination designation unit 31, the display control unit 23 reads the data of the destination designation screen held in the storage unit 32 and displays the destination designation screen on the LCD 12a. Here, when the user performs an opening operation of the flap 15 in the standby state, a destination designation screen is displayed on the LCD 12a. For this reason, it is not necessary to perform an operation of displaying a destination designation screen and an operation of opening the flap 15 when making a call, and the operation for answering an incoming call is not complicated compared to a conventional mobile phone. The destination designation screen is a dial input screen on which number keys for inputting a destination telephone number are displayed. The standby state means at least a state in which a call is not being made and no outgoing call or incoming call is made.

  The communication control unit 22 includes an incoming call response unit 22a and a call end unit 22b. The incoming call response unit 22 a is an incoming call response unit that generates an incoming call response signal based on the detection signal of the open / close detection sensor 18. The incoming call response unit 22a transmits an incoming call response signal, so that a communication path is established and a call can be started. Here, when the user performs an opening operation of the flap 15 during an incoming call, an incoming response signal is generated and transmitted to the cellular base station. That is, the opening operation of the flap 15 functions as an off-hook operation for incoming call response. For this reason, it is not necessary to perform an off-hook operation and an opening operation of the flap 15 at the time of answering an incoming call, and the operation at the time of answering an incoming call is not complicated compared to a conventional mobile phone.

  The call end unit 22 b is a call end unit that ends the call based on the detection signal of the open / close detection sensor 18. When the user performs a closing operation of the flap 15 during a call, the call is ended. That is, the closing operation of the flap 15 functions as an on-hook operation for ending the call. For this reason, it is not necessary to perform an on-hook operation and a flap 15 closing operation at the end of the call, and the operation at the end of the call is not complicated as compared with a conventional mobile phone.

  FIG. 6 is a diagram showing a dial input screen as an example of a destination designation screen displayed on LCD 12a in FIG. The dial input screen is a screen for inputting a telephone number of a call destination, and is displayed when a user operation for opening the flap 15 is performed.

  The dial input screen includes a number display area A1 and a key display area A2 formed below the number display area A1. The telephone number input by the user is displayed in the number display area A1. In the key display area A2, a plurality of input keys 41, an off-hook key 42, and a delete key 43 are arranged. The input key 41 is a key for inputting a telephone number. Here, the input keys 41 corresponding to the numbers “1” to “9”, “*”, “0”, and “#” are arranged and arranged. Yes. By selecting any one of the input keys 41, a number or symbol corresponding to the input key 41 is input. The off-hook key 42 is a key to which an off-hook function is assigned. The delete key 43 is a key for deleting one character from the end of the input number.

  Steps S101 to S113 in FIG. 7 and FIG. 8 are flowcharts showing an example of the operation in the mobile phone 1 in FIG. 1, and an example of a call process is shown. This flowchart is executed in the standby state. First, the communication control unit 22 determines whether an incoming signal has been received (step S101). If no incoming signal has been received, the destination designation unit 31 determines whether or not the flap 15 has been opened (step S102). If the flap 15 has not been opened, the process returns to step S101.

  On the other hand, when the flap 15 is opened, the destination designation unit 31 displays a dial input screen for inputting the destination telephone number on the LCD 12a (step S103). After the destination telephone number is input by the user on the dial input screen, the communication control unit 22 determines whether or not an off-hook operation has been performed (steps S104 and S105). If an off-hook operation for selecting the off-hook key 42 is performed, the communication control unit 22 transmits a call signal to the cellular base station (step S106). Thereafter, when the destination telephone returns an incoming call response, a call state with the destination telephone is established (step S107).

  During a call, the call end unit 22b determines whether or not the flap 15 has been closed (step S108). If the flap 15 is closed, the call end unit 22b ends the call state (step S109).

  On the other hand, when an incoming signal is received in step S101, the display control unit 23 displays on the LCD 12a that an incoming call is being made, and a ringing tone sounds and an incoming call is made (steps S110 and S111). ). The incoming call response unit 22a determines whether or not the flap 15 has been opened during the incoming call (step S112). When the opening operation of the flap 15 is performed, the incoming call response unit 22a generates an incoming call response signal to establish a call state, and the process proceeds to step S108 (step S113).

  The mobile phone 1 according to the present embodiment can cause the flap 15 to protrude rearward of the housing 10 by performing an opening operation of the flap 15. For this reason, while reducing SAR in the human head at the time of a telephone call, the radiation characteristic of planar antenna 17 can be improved.

  Further, in the cellular phone 1 according to the present embodiment, when the flap 15 is open, the planar antenna 17 is directed upward and the planar antenna 17 is opened upward. For this reason, compared with the case where the flap 15 is closed, the radiation characteristic of the planar antenna 17 can be improved.

  In the mobile phone 1 according to the present embodiment, the planar antenna 17 is disposed in the vicinity of the call receiver 11 with the flap 15 being open. For this reason, the planar antenna 17 during a call is difficult to be covered with the user's hand, and it is possible to prevent the radiation characteristics from deteriorating.

  Further, in the cellular phone 1 according to the present embodiment, the protruding portion from the housing 10 is less when the flap 15 is closed than when the flap 15 is opened. For this reason, it becomes a shape suitable for carrying and storage. Further, in the state where the flap 15 is closed, the planar antenna 17 faces the upper end surface 10A of the housing 10, so that the planar antenna 17 can be prevented from being damaged by an external force.

  In addition, since the mobile phone 1 according to the present embodiment displays a call destination designation screen based on the opening operation of the flap 15 in the standby state, the operation at the time of outgoing call becomes complicated compared to the conventional mobile phone. Never do.

  In addition, since the mobile phone 1 according to the present embodiment generates an incoming call response signal and establishes a call state based on the opening operation of the flap 15 at the time of incoming call, the incoming call response is compared with a conventional mobile phone. The operation of time is not complicated.

  Further, since the mobile phone 1 according to the present embodiment ends the call based on the closing operation of the flap 15 at the end of the call, the operation at the end of the call is complicated compared to the conventional mobile phone. Absent.
