Description

  The present invention relates to a telephone and a call control method.

  Conventionally, a telephone has been provided with a hold button for temporarily blocking a call and putting a melody on a call partner in a hold state. The hold button is provided on the phone casing or on the touch panel screen of the phone. Patent Document 1 below discloses a mobile phone in which a hold button is provided in a housing portion.

JP 2002-271473 A

  However, even if it is desired to place a hold during a call, the position of the hard key of the hold button provided on the telephone may be difficult to understand. Further, when the backlight on the telephone display is turned off and the position of the soft key of the hold button displayed on the touch panel screen cannot be confirmed, it cannot be immediately put on hold. For this reason, instead of pressing the hold button, there is a case where the microphone is pressed with a finger to try to prevent the other party from hearing the surrounding voice. However, simply pressing the microphone with your finger does not completely block the surrounding sounds, and the other party can hear the surrounding sound or touch the microphone with your finger. I hear it.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide a telephone and a call control method capable of controlling a call with an intuitive operation without pressing a button.

In order to solve the above-described problems, the present invention provides a microphone that collects sound during a call, a communication unit that transmits sound collected by the microphone to a call partner and receives sound from the call partner, and received sound. Is provided in the vicinity of the microphone, the first proximity detecting means for detecting the proximity of the first object, and the second target provided at a position different from the position where the first proximity detecting means is provided. The second proximity detection means for detecting the proximity of the object and the first proximity detection means detect the proximity of the first object, and the second proximity detection means does not detect the proximity of the second object Control means for stopping transmission of the sound collected by the microphone , the earphone is connected to the speaker, the first proximity detecting means detects the proximity of the first object, and , The second proximity detection means of the second object If not detected contact, communication means that sends sound to be collected by the microphone.

In the present invention, when the first proximity detection unit detects the proximity of the first object and the second proximity detection unit does not detect the proximity of the second object, the sound collected by the microphone Stop sending Thus, for example, the user can automatically stop sending the surrounding voice to the other party of the call by moving the telephone away from the face and bringing the finger close to the microphone. Therefore, the user can control the call with an intuitive operation without pressing a button. Also, when the user is using a mobile phone with an earphone connected during a call, the user listens to the voice from the other party with the earphone, but makes a call with the mouth close to the microphone of the mobile phone. For this reason, although the user's finger is not in the situation of being close to the first proximity detection means, only the first proximity detection means detects proximity. Therefore, when the earphone is connected to the speaker, even if only the first proximity detecting means detects proximity, the sound collected by the microphone is transmitted to the other party. Thereby, the telephone call control method suitable for the use condition of the mobile phone can be provided. Here, the “earphone” is a component having only a sound output function and not a microphone function. The “earphone” does not include an earphone microphone in which an audio output function and a microphone function are integrated.

  Further, when the first proximity detection means detects the proximity of the first object and the second proximity detection means does not detect the proximity of the second object, the control unit collects sound by the microphone. It is desirable to stop the transmission of voice and transmit the hold sound to the other party through the communication means. According to this configuration, the user can automatically place the telephone on the hold state only by moving the telephone away from the face and bringing the finger close to the microphone.

  The second proximity detection means is preferably provided in the vicinity of the speaker. According to this configuration, for example, it is possible to more accurately detect that the user has moved the telephone away from the face.

  The first proximity detector and the second proximity detector are preferably proximity sensors. It is possible to more accurately detect that the user has moved the telephone away from the face and that the finger has been brought close to the microphone.

  It is desirable to further disable the operation of the touch panel when the second proximity detection means detects the proximity of the second object, further including display means equipped with a touch panel. In a mobile phone including a display unit equipped with a touch panel, when the second proximity detection unit detects the proximity of the second object, it is considered that the user is approaching the touch panel. Therefore, when the user brings his / her face close to the touch panel, invalidating the operation of the touch panel can prevent a malfunction that occurs when the touch panel reacts to the ears or cheeks.

  In a state where the first proximity detection means detects the proximity of the first object and the second proximity detection means does not detect the proximity of the second object, the first proximity detection means is further set from the time when the state is reached. When the second proximity detection means detects the proximity of the second object when the time goes back in the past, it is desirable to stop the transmission of the sound collected by the microphone. Accordingly, for example, by detecting according to a change in the grip of the telephone in order for the user to cut off surrounding sounds, it is possible to automatically stop transmitting surrounding sounds to the other party. As described above, since the call control is performed for the first time when the user states at a plurality of times are detected, an intuitive operation by the user can be detected more accurately.

  It is desirable that the second proximity detection means detects the contact of the second object as the proximity of the second object. As a result, for example, even when there is a telephone near the user's ear, it is possible to automatically stop sending surrounding voices to the other party by detecting when the grip of the telephone changes. Therefore, an intuitive operation by the user can be detected even under the condition where the second object is close to the second proximity detection means.

  By the way, the present invention can be described as the invention of the telephone as described above, and can also be described as the invention of the call control method as follows. This is substantially the same invention only in different categories, and has the same operations and effects.

That is, a call control method according to the present invention includes a microphone that collects ambient sound during a call, a communication unit that transmits sound collected by the microphone to a call partner and receives sound from the call partner, A speaker for outputting the sound, a first proximity detector provided near the microphone, a second proximity detector provided at a position different from the position where the first proximity detector is provided, and control A first proximity detection step for detecting the proximity of the first object by the first proximity detection means, and a second proximity detection means for detecting the proximity of the second object. When the proximity of the first object is detected in the second proximity detection step for detecting proximity and the first proximity detection step, and the proximity of the second object is not detected in the second proximity detection step. , Look-containing and a control step of stopping the transmission of the sound collected by the microphone by the control means, the earphone is connected to the speaker, the first proximity detection step approach of the first object is detected In addition, when the proximity of the second object is not detected by the second proximity detector , the communication control method transmits the sound collected by the microphone .

  According to the present invention, it is possible to control a call with an intuitive operation without pressing a button.

  Returning to FIG. 2, the cellular phone 10 functionally includes a communication unit 14, a first proximity detection unit 15, a second proximity detection unit 16, a holding sound output unit 17, and a control unit 18.

  The communication unit 14 is a communication unit that performs a wireless communication function of the mobile phone 10. Specifically, the communication unit 14 receives the voice from the other mobile phone M via the wireless network NW, and transmits the voice collected by the microphone 11 to the other mobile phone M. When the communication unit 14 detects the establishment of a connection (call connection) between the communication unit 14 and another mobile phone M, the communication unit 14 transmits call information indicating that a call is in progress to the first proximity detection unit 15 and the second proximity detection unit 16. Output to.

  The communication unit 14 stops transmission / reception of audio to / from another mobile phone M under the control of the control unit 18. Further, the communication unit 14 transmits the hold sound output by the hold sound output unit 17 to the other mobile phone M while the transmission / reception of the sound with the other mobile phone M is stopped. Transmission / reception of voice and transmission of hold sound by the communication unit 14 are controlled by the control unit 18.

  The first proximity detection unit 15 detects the first proximity when the distance to the first object near the first proximity detection unit 15 of the mobile phone 10 is shorter than a predetermined distance (for example, 5 cm). First proximity detection means for detecting that the first object is close to the unit 15. The first proximity detection unit 15 is provided in the vicinity of the microphone 11 and includes, for example, a proximity sensor. The first proximity detection unit 15 is provided at a predetermined distance from the microphone 11 and is disposed at a distance at which the microphone 11 and the proximity sensor can be closed with one finger. For example, the first proximity detection unit 15 is provided several mm to several tens mm away from the microphone 11. When the call information is input from the communication unit 14, the first proximity detection unit 15 activates the proximity sensor, continuously detects the distance to the first object, and displays a detection result corresponding to the detected distance. Output to the control unit 18.

  The first proximity detector 15 approaches the first proximity detector 15 when the distance to the first object near the first proximity detector 15 is shorter than a predetermined distance (for example, 5 cm). The first proximity information indicating that there is something is output to the control unit 18. On the other hand, the first proximity detector 15 is close to the first proximity detector 15 when the distance to the first object near the first proximity detector 15 is longer than a predetermined distance (for example, 5 cm). When there is no object, the first non-proximity information indicating that there is no object close to the first proximity detector 15 is output to the controller 18.

  When the distance to the second object near the second proximity detection unit 16 is shorter than a predetermined distance (for example, 5 cm), the second proximity detection unit 16 detects that the second object is in the second proximity. Second proximity detection means for detecting proximity to the detection unit 16. The second proximity detection unit 16 is provided in the vicinity of the speaker 12 and includes, for example, a proximity sensor. The second proximity detection unit 16 is provided at a predetermined distance from the speaker 12 so that it can detect that the face of the user such as an ear or a part of another body has approached the speaker 12. Be placed. For example, the second proximity detector 16 is provided several mm to several tens mm away from the speaker 12. When the call information is input from the communication unit 14, the second proximity detection unit 16 activates the proximity sensor and continuously detects the distance to the second object, and the detection result according to the detected distance. Output to the control unit 18.

  The second proximity detector 16 detects the second proximity when the distance to the second object near the second proximity detector 16 of the mobile phone 10 is shorter than a predetermined distance (for example, 5 cm). Second proximity information indicating that there is something close to the unit 16 is output to the control unit 18. On the other hand, the second proximity detection unit 16 is close to the second proximity detection unit 16 when the distance to the second object near the second proximity detection unit 16 is longer than a predetermined distance (for example, 5 cm). If there is no object, the second non-proximity information indicating that there is no object in proximity to the second proximity detector 16 is output to the controller 18.

  As proximity sensors used as the first proximity detection unit 15 and the second proximity detection unit 16, various types of sensors such as an induction type, a capacitance type, an ultrasonic type, an electromagnetic wave type, and an infrared type can be used as appropriate. However, in the present embodiment, for example, an infrared proximity sensor is used. Note that the proximity sensor does not calculate the distance to the first object or the second object, but simply detects that the first object or the second object has approached based on the physical quantity itself detected by the proximity sensor. It doesn't matter if you do.

  The holding tone output unit 17 outputs a holding tone to be transmitted to the other mobile phone M via the communication unit 14 while the communication unit 14 is not transmitting and receiving voice to and from the other mobile phone M. It is. The hold sound output unit 17 stops outputting the hold sound while the communication unit 14 transmits and receives audio to and from the other mobile phone M, and transmits and receives audio to and from the other mobile phone M. If not, a hold sound is output to the communication unit 14. The output of the holding sound by the holding sound output unit 17 is controlled by the control unit 18.

  When the first proximity detection unit 15 detects the first object and the second proximity detection unit 16 does not detect the second object, the control unit 18 communicates with another mobile phone M. The control means for stopping the transmission / reception of voice. Based on the detection results input from the first proximity detection unit 15 and the second proximity detection unit 16, the control unit 18 stops audio transmission / reception with the other mobile phone M performed by the communication unit 14. As a method for stopping transmission (input) of sound, there is a case where sound collection by the microphone 11 is disabled or transmission of sound to the other mobile phone M by the communication unit 14 is stopped. As a method for stopping the reception (output) of the sound, there is a case where the sound output from the speaker 12 is disabled or the reception of the sound from the other mobile phone M by the communication unit 14 is stopped.

  When the transmission / reception of the voice is stopped by the above-described method, the control unit 18 transmits the hold sound output from the hold sound output unit 17 to another mobile phone 10 and controls the speaker 12 to output the hold sound. To do. On the other hand, when the transmission / reception of the sound is not stopped by the above-described method, the transmission of the hold sound output from the hold sound output unit 17 to the other mobile phone 10 is stopped and the output of the hold sound by the speaker 12 is stopped. To control. Further, the control unit 18 controls the touch panel operation on the display unit 13 to be valid or invalid based on the detection results input from the first proximity detection unit 15 and the second proximity detection unit 16.

  Here, the control method of the display part 13, the communication part 14, and the music on hold output part 17 performed by the control part 18 is demonstrated concretely. FIG. 4 is an explanatory diagram of an operation in which the mobile phone 10 is put on hold. As shown in FIG. 4, when the user closes the microphone 11 with a finger and the user's finger is close to the first proximity detector 15, nothing is close to the second proximity detector 16. First proximity information is input from the first proximity detection unit 15, and second non-proximity information is input from the second proximity detection unit 16.

  In the state shown in FIG. 4, the control unit 18 stops voice transmission / reception with the other mobile phone M by the communication unit 14. At the same time, the control unit 18 transmits the hold sound output from the hold sound output unit 17 to the other mobile phone M via the communication unit 14 and outputs the hold sound from the speaker 12. At this time, the operation of the touch panel of the display unit 13 is effective. As a scene where there is something close to the first proximity detection unit 15 and no thing close to the second proximity detection unit 16, for example, the user removes the mobile phone from the ear and holds the microphone 11 with a finger. The case where it is blocking is assumed.

  On the other hand, when the first proximity information is input from the first proximity detection unit 15 and the information indicating the second proximity information is input from the second proximity detection unit 16, the control unit 18 is controlled by the communication unit 14. While performing voice transmission / reception with another mobile phone M, the operation of the touch panel of the display unit 13 is invalidated. For example, there is a case where the user is in proximity to the first proximity detector 15 and a scene in which the user is close to the second proximity detector 16. Is assumed.

  In addition, when the first proximity information is input from the first proximity detection unit 15 and the second proximity information is input from the second proximity detection unit 16, the control unit 18 receives another portable by the communication unit 14. While performing voice transmission / reception with the telephone M, the operation of the touch panel of the display unit 13 is invalidated. As a scene in which there is nothing close to the first proximity detection unit 15 and there is something close to the second proximity detection unit 16, for example, when the user is talking with the mobile phone 10 close to the ear Is assumed.

  In addition, when the first proximity information is input from the first proximity detection unit 15 and the second proximity information is input from the second proximity detection unit 16, the control unit 18 receives another information from the communication unit 14. While performing transmission / reception of audio | voice with the mobile telephone M, operation of the touch panel of the display part 13 is validated. As a scene where there is no user in proximity to the first proximity detector 15 and the second proximity detector 16, a case where the user is talking hands-free is assumed.

  Next, a call control method executed by the mobile phone 10 will be described. The processing by the mobile phone M is executed by the mobile phone 10 according to the flowchart shown in FIG. FIG. 5 is a flowchart showing a call control processing procedure.

  In this process, first, a call is made with another mobile phone M via the wireless network NW (S01). When the connection is established between the communication unit 14 and another mobile phone M, the communication unit 14 outputs call information indicating that a call is in progress to the first proximity detection unit 15 and the second proximity detection unit 16.

  When the call information is input from the communication unit 14, the first proximity detection unit 15 receives the first proximity detection unit 15 based on the fact that the distance between the first proximity detection unit 15 and the first object is shorter than a predetermined distance. It is detected whether or not the first object is in proximity to the one proximity detection unit 15 (S02, first proximity detection step), and the detection result is output to the control unit 18.

  When the first proximity detection unit 15 detects that the first object is approaching the first proximity detection unit 15, the first proximity detection unit 15 outputs the first proximity information to the control unit 18, and the first proximity detection unit 15 If it is not detected that one object is close, the first non-proximity information is output to the control unit 18. Note that during the user's call, the proximity detection of the first object by the first proximity detection unit 15 and the output of the detection result to the control unit 18 are continuously performed after the first proximity detection step.

  When the call information is input from the communication unit 14, the second proximity detection unit 16 receives the first proximity detection unit 16 based on the fact that the distance between the second proximity detection unit 16 and the second object is shorter than a predetermined distance. It is detected whether or not the second object is close to the second proximity detection unit 16 (S03, second proximity detection step), and the detection result is output to the control unit 18.

  When the second proximity detection unit 16 detects that the second object is approaching the second proximity detection unit 16, the second proximity detection unit 16 outputs the second proximity information to the control unit 18, and the second proximity detection unit 16 outputs the second proximity information to the second proximity detection unit 16. When it is not detected that the two objects are close to each other, the second non-proximity information is output to the control unit 18. During the user's call, the proximity detection of the second object by the second proximity detection unit 16 and the output of the detection result to the control unit 18 are continuously performed after the second proximity detection step.

  Subsequently, the control unit 18 determines whether the first object is in proximity to the first proximity detection unit 15 and whether the second object is not in proximity to the second proximity detection unit 16. Obtain (S04). When the first proximity information is output from the first proximity detection unit 15 and the second non-proximity information is output from the second proximity detection unit 16 (S04; YES), the control unit 18 performs other processing by the communication unit 14. The voice transmission / reception with the mobile phone M is stopped (control step). In addition, the control unit 18 transmits the hold sound output from the hold sound output unit 17 to the other mobile phone M via the communication unit 14, and outputs the hold sound from the speaker 12 to enter the hold state (S05). . The control unit 18 validates the operation of the touch panel of the display unit 13.

  On the other hand, if the first proximity information is output from the first proximity detector 15 and the second non-proximity information is not output from the second proximity detector 16 (S04; NO), the controller 18 detects the first proximity. The mobile phone 10 is not put on hold until the first proximity information is output from the unit 15 and the second non-proximity information is output from the second proximity detection unit 16.

  In this case, when the second proximity information is output from the second proximity detector 16, the control unit 18 validates the operation of the touch panel of the display unit 13, and the second proximity information is received from the second proximity detector 16. If output, the operation of the touch panel of the display unit 13 is invalidated. That is, when the first proximity detection unit 15 outputs the first non-proximity information and the second proximity detection unit 16 outputs the second non-proximity information, the operation of the touch panel of the display unit 13 is validated. On the other hand, the first proximity information is output from the first proximity detection unit 15 and the second proximity information is output from the second proximity detection unit 16, and the first non-proximity information is output from the first proximity detection unit 15. When the second proximity information is output from the second proximity detector 16, the operation of the touch panel of the display unit 13 is invalidated.

  Subsequently, in the hold state, the control unit 18 acquires information on whether or not the first object is in a state of being in proximity to the first proximity detection unit 15 (S06). When the first proximity information is output from the first proximity detection unit 15 (S06; NO), the control unit 18 transmits a hold sound to another mobile phone M or holds from the speaker 12. While outputting the sound is stopped, the transmission / reception of the voice with the other mobile phone M by the communication unit 14 is resumed, and the hold state is released (S07). In addition, the call is resumed simultaneously with the release of the hold state. At this time, when the second proximity information is output from the second proximity detection unit 16, the control unit 18 enables the operation of the touch panel of the display unit 13, and the second proximity information is received from the second proximity detection unit 16. If it is output, the operation of the touch panel of the display unit 13 is invalidated. When the call is resumed, the control unit 18 is in a state where the first object is close to the first proximity detector 15 and the second object is not close to the second proximity detector 16. Is acquired again (S04). Then, S04 to S07 are repeated until the call ends.

  On the other hand, when the first proximity information is output from the first proximity detection unit 15 in the hold state (S06; YES), the control unit 18 causes the first object to approach in the hold state. Stay on hold until it is no longer detected. In addition, when the second non-proximity information is output from the second proximity detection unit 16, the control unit 18 enables the operation of the touch panel of the display unit 13 and outputs the second proximity information from the second proximity detection unit 16. If so, the operation of the touch panel of the display unit 13 is invalidated.

  In the above flowchart, in the hold state, the first proximity detection unit 15 outputs the first non-proximity information to release the hold state, but the second proximity detection unit 16 outputs the second proximity information. The hold state may be released on the condition that it has been done. In this case, the control unit 18 invalidates the operation of the touch panel of the display unit 13.

  As described above, in the mobile phone 10 according to the present embodiment, the first proximity detector 15 detects that the first object is close to the first proximity detector 15, and the second proximity detector 16 When it is not detected that the second object approaches the second proximity detector 16, the call with another mobile phone M is put on hold. In this case, while the user moves the mobile phone 10 away from the face, a call with another mobile phone M can be automatically put on hold simply by bringing a finger close to the microphone 11. Therefore, the user can control the call with an intuitive operation without pressing a button.

  In the present embodiment, the second proximity detector 16 is provided in the vicinity of the speaker 12. In this case, it is possible to more accurately detect that the user has moved the telephone away from the face.

  The first proximity detector 15 and the second proximity detector 16 are proximity sensors. In this case, it is possible to more accurately detect that the user has moved the mobile phone 10 away from the face and that the finger has been brought close to the microphone.

  Moreover, in this embodiment, when the 2nd proximity detection part 16 is further provided with the display part 13 carrying a touch panel and has detected the proximity | contact of a user's face, operation of a touch panel is invalidated. In this case, when the user brings his / her face close to the touch panel, it is possible to prevent a malfunction that occurs when the touch panel reacts to the ears or cheeks.

  In the above, it explained in detail based on the embodiment of the present invention. However, the present invention is not limited to the above embodiment. The present invention can be variously modified as follows.

  In the present embodiment, the case where the mobile phone 10 is used as the telephone has been described, but the present invention can also be applied to the case where a fixed telephone is used as the telephone. In this case, the first proximity detector 15 is provided in the vicinity of the receiver of the landline telephone receiver, and the second proximity detector 16 is provided in the vicinity of the transmitter so that the user's face is close to the receiver and the surrounding area. It is possible to detect that the user is blocking the earpiece with a finger so that the other party cannot hear the voice.

  In the present embodiment, the earphone is not connected to the speaker 12, but when the earphone is connected to the speaker 12, the first proximity detection unit 15 is close to the first proximity detection unit 15. Even when the second proximity detector 16 has not detected the proximity of the second object to the second proximity detector 16, the voice is communicated with the other mobile phone M. Send and receive. When the user is using the mobile phone 10 with the earphone connected during a call, the user listens to the sound from the other mobile phone M through the earphone, but makes a call with the mouth close to the microphone 11 of the mobile phone 10. . For this reason, since only the first proximity detection unit 15 detects proximity, the control unit 18 is not in a situation where the user's finger is close to the first proximity detection unit 15 but the user's finger is close. It will be the same situation. Therefore, when the earphone is connected to the speaker 12, it is detected that the first object is close to the first proximity detector 15, and the second object is detected to the second proximity detector 16. Even when it is not detected that an object is in close proximity, the communication unit 14 transmits and receives audio to and from another mobile phone M. Thereby, the call control method suitable for the use situation of the mobile phone 10 can be provided. When the earphone is connected to the speaker, the control unit 18 controls the other party's voice to be output from the earphone during a call, and controls the hold sound to be output from the earphone when the call is on hold.

  In this embodiment, it is determined that the user's face or finger and the mobile phone 10 are close to the first proximity detection unit 15 and the second proximity detection unit 16 because the proximity sensor detects proximity to the detected object. The method of determining the proximity between the user's face or finger and the mobile phone 10 is not limited to this. For example, an illuminance sensor is used in place of the proximity sensor, and on the condition that the illuminance sensor senses darkness, it is detected that there is something close to the first proximity detection unit 15 and the second proximity detection unit 16. May be.

(Second Embodiment)
The second embodiment, which is a preferred embodiment of the present invention, will be described with a focus on differences from the first embodiment. The mobile phone 20 according to the second embodiment includes a second proximity detection unit 26 and a control unit 28 instead of the second proximity detection unit 16 and the control unit 18 of the mobile phone 10 according to the first embodiment. That is, the cellular phone 20 according to the second embodiment functionally includes a communication unit 14, a first proximity detection unit 15, a second proximity detection unit 26, a holding tone output unit 17, and a control unit 28.

  The second proximity detection unit 16 according to the first embodiment and the second proximity detection unit 26 according to the second embodiment are different in conditions for detecting the proximity of the second object and the positions where they are arranged. The control unit 18 according to the first embodiment and the control unit 28 according to the second embodiment have different conditions for placing a call with another mobile phone M on hold.

  Specifically, the second proximity detection unit 16 determines that the second target object when the distance to the second target object near the second proximity detection unit 16 is shorter than a predetermined distance (for example, 5 cm). Is detected to be close to the second proximity detector 16. On the other hand, the second proximity detector 26 detects that the second object is in proximity to the second proximity detector 26 when the second object comes into contact with the second proximity detector 26. That is, the second proximity detection unit 26 outputs the second proximity information to the control unit 28 when the second object comes into contact with the second proximity detection unit 26. On the other hand, the second proximity detection unit 26 outputs the second non-proximity information to the control unit 28 when the second object is not in contact with the second proximity detection unit 26.

  The second proximity detection unit 16 is provided in the vicinity of the speaker 12. For example, the second proximity detection unit 16 includes a proximity sensor and is provided at a predetermined distance from the speaker 12. It was placed at a distance that could detect that the face and other body parts were approaching. On the other hand, the second proximity detection unit 26 is disposed at a location where a user's finger holding the mobile phone 20 contacts during a call. FIG. 6 is a diagram illustrating a state in which the user grips the mobile phone 20 according to the second embodiment during a call. As shown in FIG. 6, in the mobile phone 20, a back surface 20b opposite to the surface 20a on which the display unit 13 is provided, a right side surface 20c, and a left side surface 20d are gripping portions, and the user can make a call Holding the grip inside. In the second embodiment, the second proximity detection unit 26 includes, for example, a contact sensor (touch sensor), and is provided on the left side surface 20d where the thumb of the user holding the mobile phone 20 with the left hand contacts during a call. ing. The second proximity detection unit 26 may be provided on the right side surface 20c. In this case, the user's thumb holding the mobile phone 20 with the right hand during a call contacts the second proximity detection unit 26. . Further, as shown in FIG. 6, the second proximity detection unit 26 may be large enough to be blocked by a finger, or may be large enough to occupy half or more of the right side 20c or the left side 20d.

  In addition, the control unit 18 detects that the first proximity detection unit 15 is approaching the first proximity detection unit 15, and the second proximity detection unit 16 is the second proximity detection unit 16. In the case where it is not detected that the second object is close to the mobile phone M, a call with another mobile phone M is put on hold. In contrast, the control unit 28 is in a state where the first proximity detection unit 15 detects the proximity of the first object and the second proximity detection unit 26 does not detect the proximity of the second object. Furthermore, when the second proximity detection unit 26 detects the proximity of the second object when the time set in the past from the time when the state is reached, a call with another mobile phone M is performed. Is determined to be put on hold.

  That is, the control unit 28 can recognize the second proximity information and the second non-proximity information output from the second proximity detection unit 26 at an interval (for example, every second) at which the user can change how the mobile phone 20 is held. ) Continuously and the acquired information is held in the control unit 28. Note that the interval at which the second proximity detection unit 26 acquires the second proximity information or the second non-proximity information can be set in advance in the control unit 28 by a user operation.

  In addition to the determination in the first embodiment, the control unit 28 receives the first proximity information from the first proximity detection unit 15 and the second proximity information from the second proximity detection unit 26. The information input from the second proximity detection unit 26 is searched retroactively from the time when the information and the second non-proximity information are input, and the second object is detected as the second proximity detection unit. It is determined whether or not to place a hold state depending on whether or not the second proximity information has been input a predetermined number of times (for example, two to three times or more) that can be surely contacted with 26. The time set in advance from the time when the first proximity information and the second non-proximity information are input is, for example, a time when the second object can be recognized as reliably contacting the second proximity detection unit 26, and This is the total time that can be recognized when the way of holding the telephone 20 is changed, and can be set in advance in the control unit 28 by a user operation. In addition, the control part 28 will be in a holding | maintenance state, if the 2nd proximity information is input once even after the preset time past from the time the 1st proximity information and the 2nd proximity information were input. You may judge.

  When the second proximity information is input from the second proximity detection unit 26 a predetermined number of times, the control unit 28 determines that the mobile phone 20 is put on hold. On the other hand, when the second proximity information is not input from the second proximity detector 26 a predetermined number of times, the control unit 28 determines that the mobile phone 20 is not put on hold.

  FIG. 7 is an explanatory diagram of an operation in which the mobile phone 20 according to the second embodiment is put on hold. For example, as shown in FIG. 6, an intuitive operation that is performed when the user wants to place the mobile phone 20 on hold while the user is holding the mobile phone 20 is shown in FIG. Alternatively, as shown in FIG. 7, it is conceivable to perform an operation of closing the microphone 11 with the thumb while supporting only the back surface 20b of the mobile phone 20 with a finger.

  Here, when the user performs the above-described operation, a control method of the display unit 13, the communication unit 14, and the hold tone output unit 17 executed by the control unit 28 will be specifically described. First, as shown in FIG. 6, when the user's thumb as the second object is in contact with the second proximity detection unit 26, the second proximity information is input from the second proximity detection unit 26 to the control unit 28. The Then, as shown in FIG. 7, after the user's thumb leaves the second proximity detection unit 26, the thumb closes the microphone 11, and the user's finger is close to the first proximity detection unit 15. When there is nothing in contact with the second proximity detection unit 26, the first proximity information is input from the first proximity detection unit 15 and the second non-proximity information is input from the second proximity detection unit 26 to the control unit 28. The

  The controller 28 changes from the state shown in FIG. 6 to the state shown in FIG. 7, the first proximity detector 15 detects the proximity of the first object, and the second proximity detector 26 is the second. When the proximity of the target object is not detected, and the second proximity detection unit 26 detects the proximity of the second target object when going back to the past time set from the time when the target state is reached. If it judges, transmission / reception of an audio | voice with the other mobile telephone M by the communication part 14 will be stopped. At the same time, the control unit 28 transmits the hold sound output from the hold sound output unit 17 to the other mobile phone M via the communication unit 14 and outputs the hold sound from the speaker 12. At this time, the operation of the touch panel of the display unit 13 is effective. When the state shown in FIG. 7 is further returned to the state shown in FIG. 6, the first non-proximity information is input from the first proximity detection unit 15 to the control unit 28, and the second proximity information is received from the second proximity detection unit 26. Entered. Then, the control unit 28 performs voice transmission / reception with the other mobile phone M through the communication unit 14 and invalidates the operation of the touch panel of the display unit 13.

  Subsequently, in the second embodiment, a call control method executed by the mobile phone 20 will be described focusing on differences from the first embodiment. The processing by the mobile phone M is executed by the mobile phone 20 according to the flowchart shown in FIG. FIG. 8 is a flowchart showing a call control processing procedure.

  In this process, first, a call is made with another mobile phone M via the wireless network NW (S11). When the connection is established between the communication unit 14 and another mobile phone M, the communication unit 14 outputs call information indicating that a call is in progress to the first proximity detection unit 15 and the second proximity detection unit 26.

  When the call information is input from the communication unit 14, the first proximity detection unit 15 receives the first proximity detection unit 15 based on the fact that the distance between the first proximity detection unit 15 and the first object is shorter than a predetermined distance. It is detected whether or not the first object is close to the one proximity detection unit 15 (S12, first proximity detection step), and the detection result is output to the control unit 28.

  When the first proximity detection unit 15 detects that the first object is close to the first proximity detection unit 15, the first proximity detection unit 15 outputs the first proximity information to the control unit 28, and the first proximity detection unit 15 If it is not detected that one object is close, the first non-proximity information is output to the control unit 28. During the user's call, the proximity detection of the first object by the first proximity detection unit 15 and the output of the detection result to the control unit 28 are continuously performed after the first proximity detection step.

  When the call information is input from the communication unit 14, the second proximity detector 26 receives the second object from the second proximity detector 26 based on the contact of the second object with the second proximity detector 26. Are detected (S13, second proximity detection step), and the detection result is output to the control unit 28.

  When the second proximity detection unit 26 detects that the second object is approaching the second proximity detection unit 26, the second proximity detection unit 26 outputs second proximity information to the control unit 28, and the second proximity detection unit 26 outputs the second proximity information to the second proximity detection unit 26. When it is not detected that the two objects are close to each other, the second non-proximity information is output to the control unit 28. During the user's call, the proximity detection of the second object by the second proximity detection unit 26 and the output of the detection result to the control unit 28 are continuously performed after the second proximity detection step.

  In the second embodiment, in the control step (S14 and S15), the condition that the control unit 28 puts the call with another mobile phone M on hold is different from the control unit 18 in the first embodiment. That is, in the second embodiment, first, in S14, the control unit 28 causes the first object to approach the first proximity detector 15 and the second object to approach the second proximity detector 26. Information on whether or not the state is not present is acquired (S14). When the first proximity information is output from the first proximity detection unit 15 and the second non-proximity information is output from the second proximity detection unit 26 (S14; YES), the control unit 28 sets the first proximity information and The information output to the control unit 28 is retrieved retroactively from the time when the second non-proximity information is output, and depending on whether or not the second proximity information is output a predetermined number of times, the pending state It is determined whether or not (S15).

  On the other hand, when the first proximity information is output from the first proximity detector 15 and the second non-proximity information is not output from the second proximity detector 26 in S14 (S14; NO), the controller 28 The information on whether or not the first object is in proximity to the first proximity detector 15 at the time (time) and the second object is not in proximity to the second proximity detector 26 is continuously acquired. Keep doing.

  Next, in S15, when the information output to the control unit 28 is retrieved retroactively from the time when the first proximity information and the second non-proximity information are output, the second proximity detection unit When it is detected that the second proximity information has been output a predetermined number of times from S26 (S15; YES), the control unit 28 stops transmission / reception of voice to / from another mobile phone M by the communication unit 14. Further, the control unit 28 transmits the hold sound output from the hold sound output unit 17 to the other mobile phone M via the communication unit 14, and outputs the hold sound from the speaker 12 to enter the hold state (S16). . Note that the control unit 28 validates the operation of the touch panel of the display unit 13. Further, the steps from the hold state (S16) to the hold release (S18) are the same as S5 to S7 of the first embodiment.

  On the other hand, in S15, when the information output to the control unit 28 is retrieved retroactively from the time when the first proximity information and the second non-proximity information are output, the second proximity detection unit 26 is searched. If it is not detected that the second proximity information has not been output a predetermined number of times (S15; NO), the control unit 28 indicates that the first object is in proximity to the first proximity detection unit 15 and the second Information on whether or not the second object is not in proximity to the proximity detector 26 starts to be acquired again (S14). Further, the control unit 28 leaves the operation of the touch panel of the display unit 13 invalid.

  As described above, in the mobile phone 20 according to the second embodiment, in the control unit 28, the first proximity detector 15 detects the proximity of the first object, and the second proximity detector 26 is the first. In a state in which the proximity of the two objects is not detected, the second proximity detection unit 26 detects the proximity of the second object when the time set back from the time when the state is changed to the past. In this case, a call with another mobile phone M is put on hold. Thus, in order for the user to block ambient sounds, the user who is talking on the phone changes the grip of the mobile phone 20, and the user's thumb is in contact with the second proximity detection unit 26. By detecting that the mobile phone M is away from the second proximity detector 26, a call with another mobile phone M can be put on hold. Therefore, since the call control is performed for the first time when the state of the user at a plurality of times is detected, an intuitive operation by the user can be detected more accurately.

  In the second embodiment, the second proximity detector 26 detects the contact of the second object as the proximity of the second object. Thereby, for example, even when the mobile phone 20 is near the user's ear, it is automatically detected that the surrounding voice is transmitted to the call partner by detecting when the grip of the mobile phone 20 changes. Can be stopped. Therefore, even when the user's hand, which is the second object, is close to the second proximity detection unit 26, an intuitive operation by the user can be detected. Also in the first embodiment, the second proximity detector 16 may detect the contact of the second object as the proximity of the second object.

  In the above, it explained in detail based on the embodiment of the present invention. However, the present invention is not limited to the above embodiment. The present invention can be variously modified as follows.

  In the present embodiment, the second proximity detector 26 is provided on the left side 20d of the mobile phone 20, but the position of the second proximity detector 26 is not limited to this. As long as it can be determined that the user has changed the grip of the mobile phone 20, the mobile phone 20 may be provided at any position, and may be provided on the same plane as the first proximity detector 15.

  In the present embodiment, the user changes the gripping state of the mobile phone 20 from the state shown in FIG. 6 to the state shown in FIG. 7 and the user can put the microphone 11 in a holding state by closing the microphone 11 with a finger. The operation of the user who sets the state is not limited to this. The holding state may be set when the user changes the grip of the mobile phone 20 from the state shown in FIG. 6 to the state shown in FIG.
