Description

  The present invention relates to a mobile radio terminal device that is used in, for example, a mobile phone system, a PHS (Personal Handyphone System), and the like, and particularly has an openable casing.

  As is well known, a mobile radio terminal device includes a receiver as a speaker for receiving calls. Recently, in addition to this, it is considered to adopt a panel speaker whose surface facing the user of the display unit functions as a speaker. Has been. According to such a panel speaker, since the output area is larger than that of a conventionally employed receiver, there is an advantage that the user can easily perform positioning on the ear.

  However, when a panel speaker is used and a ring tone or alarm sound is output loudly from this, if an incoming call is generated or an alarm sound is generated with the touch applied to the ear after the dialing operation, the user must be close to the ear. There was a problem that the alarm sound suddenly emitted was surprised.

  On the other hand, conventionally, in the case of a foldable mobile radio terminal device, when it is in an open state, a notification sound smaller than that in a closed state is generated (for example, see Patent Document 1).

However, just because it is in an open state does not necessarily mean that the user is in contact with the ear, and because the notification sound is emitted at a low volume, the user can generate an incoming call or arrive at an alarm set time. A new problem has arisen that there is a possibility that it cannot be recognized.
JP 2004-173049 A

  In the conventional mobile radio terminal device, when it is set so that the notification sound is made small in the open state, there is a problem that the user cannot recognize the generation of the notification sound and may lose a necessary opportunity. .

  The present invention has been made to solve the above-described problem, and provides a mobile radio terminal device that is easy for a user to recognize the occurrence of a notification sound and has a low risk of losing a necessary opportunity even when the notification volume is varied. For the purpose.

  In order to achieve the above object, the present invention provides a determination means for determining whether or not a mobile radio terminal apparatus is performing a transmission operation, a loudspeaker means for loudly outputting a notification sound, and a loudspeaker output from the loudspeaker means. The volume of the notification sound is controlled, and when the notification sound is amplified, if the determination means determines that the transmission operation is not being performed, the volume is controlled to the first volume, and the determination means Is determined to be in a call origination operation, the sound volume control means for controlling the sound volume to a second sound volume smaller than the first sound volume is provided.

  According to the present invention, it is possible to provide a mobile radio terminal apparatus that is easy for a user to recognize the occurrence of a notification sound and has little risk of losing a necessary opportunity even when the notification volume is varied.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows the configuration of a mobile radio terminal apparatus according to an embodiment of the present invention. This mobile wireless terminal device has a folding housing structure, and includes an antenna 1, a wireless unit 10, a camera unit 20, a display unit 30, a microphone 40, a receiver 50, a speaker control unit 51, a panel speaker 52, and key operations. Unit 60, memory 70, charge detection unit 80, open / close detection unit 90, and control unit 100.

  The radio unit 10 down-converts and demodulates the radio signal received by the antenna 1 from the radio base station BS accommodated in the mobile communication network, and encodes voice data, received mail data, or web data transmitted from the communication partner station. Is output to the control unit 100. The radio unit 10 modulates a baseband signal using the encoded voice data and transmission mail data provided from the control unit 100, up-converts the baseband signal, generates a radio signal, and transmits the radio base station BS through the antenna 1. Send to.

  The camera unit 20 is an electronic camera using a CCD (Charge-Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor), and encodes the captured image and outputs it as image data to the control unit 100.

  The display unit 30 is a display device using an LCD (Liquid Crystal Display) or the like, and is controlled by the control unit 100 to display various visual information such as text and images to the user. A panel speaker 52 is mounted on the surface of the display unit 30 facing the user.

  The microphone 40 collects the user's transmitted voice, converts it into a transmitted voice signal, and outputs it to the control unit 100. The receiver 50 is a speaker that amplifies and outputs received voice and various notification sounds based on a signal given from the control unit 100. The speaker control unit 51 drives and controls the panel speaker 52 based on a signal given from the control unit 100.

The key operation unit 60 includes a plurality of key switches and receives a user request.
The memory 70 stores the phone book data in which the control program of the control unit 100, the control data, the telephone number, the name, and the face data are associated with each other, and the transmitted and received mail data and the image captured by the camera unit 20 Data, parameters of operation settings of the mobile radio terminal device, and the like are stored.

  The charge detection unit 80 detects charger connection to a battery for operation (not shown), and notifies the control unit 100 of the detection result. When connection of the charger is detected, charging of the battery is started by power supplied from the outside by a charging circuit (not shown).

The open / close detection unit 90 detects the opening / closing of the casing of the folding mobile radio terminal device, and notifies the control unit 100 of the detection result.
The control unit 100 controls each unit of the mobile radio terminal device in an integrated manner. For example, when the radio unit 10 receives an incoming signal from a radio base station, the control unit 100 controls the display unit 30 and also controls the panel speaker 52 through the receiver 50 and the speaker control unit 51 to generate an incoming call. And an incoming call control function for establishing a voice communication link by transmitting a signal responding to the incoming call to the radio unit 10 by a user's response operation through the key operation unit 60.

  When the voice communication link is established through the radio base station BS, the control unit 100 decodes the encoded voice data demodulated by the radio unit 10 to reproduce the voice signal, and receives the receiver 50 and the panel speaker 52. Amplify output from. Thereby, the transmitted voice from the call partner station is transmitted to the user. In addition, the control unit 100 encodes the audio signal input from the microphone 40 to generate encoded audio data, and gives the encoded audio data to the radio unit 10 to be transmitted to the call partner.

  Further, the control unit 100 has an e-mail transmission / reception control function. In accordance with an instruction from the user through the key operation unit 60, a transmission mail is created and recorded in the memory 70. And according to the request | requirement from the user through the key operation part 60, the said transmission mail is read from the memory 70, the radio | wireless part 10 is controlled, and transmission mail is transmitted through the radio base station BS.

  Further, when the wireless unit 10 receives an email, the control unit 100 records the received email in the memory 70. Then, in response to a request from the user through the key operation unit 60, the received mail recorded in the memory 70 is read and displayed on the display unit 30.

  In addition, the control unit 100 has a control function for browsing web data, a control function for receiving information distributed from the radio base station BS, and a call waiting notification for notifying that the three-way communication has been restored. Control function, control function to manage schedule data, schedule alarm control function to output alarm sound aloud in conjunction with the schedule, alarm control function to output alarm sound aloud according to time, countdown for a short time like a kitchen timer A timer control function for notifying the passage of time, an alarm control function for notifying the user of a warning, a low battery warning control function for notifying that the remaining battery level has fallen below a threshold value, and confirming the operation of the key operation unit 60 Control function to output as sound, voice data of caller recorded in memory 70 at the time of absence response A simple absence recording control function for recording or reading out and reproducing this voice data, a voice memo control function for converting the voice input through the microphone 40 into data and recording it in the memory 70, and reading out and playing back the recorded voice data, etc. Is provided.

  In addition, the control unit 100 has a function of controlling the volume of sound to be generated according to the volume parameter stored in the memory 70 when the control function as described above is performed, accompanied by the operation of generating sound. Prepare. The volume parameters include a user set volume, a Max limit volume, and a hearing protection volume.

  The user-set volume can be arbitrarily set by the user among volume levels 1 to 5 (5 is maximum), step-up (gradually increasing), and step-down (gradually decreasing) that can be set by the mobile radio terminal device. The volume is set. The Max restricted volume is based on the set volume when the user-set volume is level 1, 2 or 3, but when the set volume is set to, for example, level 4 or 5, the volume is set to level. 3. When the step is set to either step-up or step-down, the maximum volume is set to level 3, and the step-down or step-up is performed between volume levels 1 to 3. The volume for hearing protection is a volume smaller than a preset level 1.

  Next, the operation of the mobile radio terminal apparatus having the above configuration will be described. In the following description, a description of a procedure for establishing a communication link with the radio base station BS, control for realizing voice communication, registration, calling, and editing of telephone directory data is omitted. The operation control for generating a sound according to the volume parameter 100 stores in the memory 70 will be described.

  FIG. 2 is a flowchart for explaining the operation control related to the incoming call. The processing shown in this flowchart is started when an incoming call occurs. Note that a control program for realizing the control shown in this flowchart is stored in the memory 70.

First, in step 2a, the control unit 100 determines whether the casing of the mobile wireless terminal device is in a closed state or an open state based on the detection result of the open / close detection unit 90. If it is determined that the housing is in a closed state, the process proceeds to step 2b. On the other hand, if it is determined that the housing is in an open state, the process proceeds to step 2c.
In step 2b, the control unit 100 reads the user-set volume parameter for incoming calls from the memory 70, sets this as the volume of the ringtone, and proceeds to step 2i.

  On the other hand, in step 2c, the control unit 100 determines whether or not the mobile wireless terminal device is performing a transmission operation. Here, when it is determined that the mobile radio terminal apparatus is performing a transmission operation, the process proceeds to step 2h, whereas when it is determined that the transmission operation is not performed, the process proceeds to step 2d. Note that when the transmission operation is in progress, the control unit 100 is preparing to control the radio unit 10 for transmission, or has already performed the control, or the user operates the key operation unit 60. This corresponds to the case of calling the phone book data or operating the off-hook key to make a call request.

  In step 2d, the control unit 100 determines whether or not the elapsed time T after the user operates the key operation unit 60 and the transmission operation associated therewith is less than a preset time n. Here, when the elapsed time T is less than the preset time n, the process proceeds to Step 2h, whereas when it is equal to or greater than the preset time n, the process proceeds to Step 2e. The elapsed time T is a time when the control unit 100 starts measuring time in response to a call request from the user to the key operation unit 60.

  In step 2e, the control unit 100 determines whether or not the transmission operation is being interrupted. If the call operation is interrupted, the process proceeds to step 2h. If the call operation is not interrupted, the process proceeds to step 2f. In addition, the state where the transmission operation is interrupted includes a state in which a transmission request is started and transmission control is started, but after that, a process in which transmission is interrupted by a request from the user through the key operation unit 60 is performed. Applicable.

  In step 2f, the control unit 100 determines whether or not the voice data (absence recording, voice memo) recorded in the memory 70 is being reproduced. If the audio data is being reproduced, the process proceeds to step 2h. If the audio data is not being reproduced, the process proceeds to step 2g.

In step 2g, the control unit 100 reads the incoming Max limit volume parameter from the memory 70, sets it as the volume of the ringtone, and proceeds to step 2i.
In step 2h, the control unit 100 reads the incoming hearing protection volume parameter from the memory 70, sets it as the volume of the ringtone, and proceeds to step 2i.

  In step 2i, the control unit 100 controls the panel speaker 52 through the receiver 50 and the speaker control unit 51 with the volume based on the set volume parameter, notifies the occurrence of an incoming call, and ends the process.

  Next, a description will be given of operation control for generating sound, which is related to key operation. FIG. 3 shows the flowchart. The process shown in this flowchart is started when the user operates the key operation unit 60. Note that a control program for realizing the control shown in this flowchart is stored in the memory 70.

First, in step 3a, the control unit 100 determines whether the casing of the mobile radio terminal device is in a closed state or an open state based on the detection result of the open / close detection unit 90. If it is determined that the housing is in a closed state, the process proceeds to step 3b. On the other hand, if it is determined that the housing is in an open state, the process proceeds to step 3c.
In step 3b, the control unit 100 reads the user-set volume parameter for key operation from the memory 70, sets this as the volume of the key operation sound, and proceeds to step 3h.

  On the other hand, in step 3c, the control unit 100 determines whether or not the mobile wireless terminal device is performing a transmission operation. Here, when it is determined that the mobile radio terminal apparatus is performing a transmission operation, the process proceeds to step 3g. On the other hand, when it is determined that the mobile radio terminal apparatus is not performing a transmission operation, the process proceeds to step 3d. Note that when the transmission operation is in progress, the control unit 100 is preparing to control the radio unit 10 for transmission, or has already performed the control, or the user operates the key operation unit 60. This corresponds to the case of calling the phone book data or operating the off-hook key to make a call request.

  In step 3d, the control unit 100 determines whether or not an elapsed time T from when the user operates the key operation unit 60 and the transmission operation associated therewith is less than a preset time n. Here, when the elapsed time T is less than the preset time n, the process proceeds to step 3g, whereas when it is equal to or greater than the preset time n, the process proceeds to step 3e. The elapsed time T is a time when the control unit 100 starts measuring time in response to a call request from the user to the key operation unit 60.

  In step 3e, the control unit 100 determines whether or not the outgoing operation is being interrupted. If the call operation is interrupted, the process proceeds to step 3g. If the call operation is not interrupted, the process proceeds to step 3f. In addition, the state where the transmission operation is interrupted includes a state in which a transmission request is started and transmission control is started, but after that, a process in which transmission is interrupted by a request from the user through the key operation unit 60 is performed. Applicable.

  In step 3f, the control unit 100 determines whether or not the voice data (answering recording, voice memo) recorded in the memory 70 is being reproduced. If the audio data is being reproduced, the process proceeds to step 3g. On the other hand, if the audio data is not being reproduced, the process proceeds to step 3b.

  In step 3g, the control unit 100 reads the hearing-protective volume parameter for key operation from the memory 70, sets this as the volume of the key operation sound, and proceeds to step 3h. In step 3h, the control unit 100 controls the panel speaker 52 through the receiver 50 and the speaker control unit 51 at a volume based on the set volume parameter, generates a key operation confirmation sound, and ends the process.

  Next, operation control for generating alarm sounds such as alarms and timers will be described. FIG. 4 shows a flowchart thereof. The processing shown in this flowchart is started when the alarm set time comes, when the timer count is completed, or when it is necessary to give some warning to the user. Note that a control program for realizing the control shown in this flowchart is stored in the memory 70.

First, in step 4a, the control unit 100 determines whether the casing of the mobile wireless terminal device is in a closed state or an open state based on the detection result of the open / close detection unit 90. If it is determined that the casing is in a closed state, the process proceeds to step 4b. On the other hand, if it is determined that the casing is in an open state, the process proceeds to step 4c.
In step 4b, the control unit 100 reads the warning user setting volume parameter from the memory 70, sets this as the volume of the warning sound, and proceeds to step 4i.

  On the other hand, in step 4c, the control unit 100 determines whether or not the mobile wireless terminal device is performing a transmission operation. Here, when it is determined that the mobile radio terminal apparatus is performing a transmission operation, the process proceeds to step 4h, whereas when it is determined that the transmission operation is not performed, the process proceeds to step 4d. Note that when the transmission operation is in progress, the control unit 100 is preparing to control the radio unit 10 for transmission, or has already performed the control, or the user operates the key operation unit 60. This corresponds to the case of calling the phone book data or operating the off-hook key to make a call request.

  In step 4d, the control unit 100 determines whether or not the elapsed time T after the user operates the key operation unit 60 and the transmission operation associated therewith is less than a preset time n. Here, if the elapsed time T is less than the preset time n, the process proceeds to step 4h. On the other hand, if the elapsed time T is equal to or greater than the preset time n, the process proceeds to step 4e. The elapsed time T is a time when the control unit 100 starts measuring time in response to a call request from the user to the key operation unit 60.

  In step 4e, the control unit 100 determines whether or not the transmission operation is being interrupted. If the call operation is interrupted, the process proceeds to step 4h. If the call operation is not interrupted, the process proceeds to step 4f. In addition, the state where the transmission operation is interrupted includes a state in which a transmission request is started and transmission control is started, but after that, a process in which transmission is interrupted by a request from the user through the key operation unit 60 is performed. Applicable.

  In step 4f, the control unit 100 determines whether or not the voice data (answering recording, voice memo) recorded in the memory 70 is being reproduced. If the audio data is being reproduced, the process proceeds to step 4h. If the audio data is not being reproduced, the process proceeds to step 4g.

In step 4g, the control unit 100 reads out the warning Max restricted volume parameter from the memory 70, sets this as the volume of the warning sound, and proceeds to step 4i.
In step 4h, the control unit 100 reads the warning hearing protection volume parameter from the memory 70, sets it as the volume of the warning sound, and proceeds to step 4i.

  In step 4i, the control unit 100 controls the panel speaker 52 through the receiver 50 and the speaker control unit 51 at a volume based on the set volume parameter, generates a warning sound, and ends the process.

  Note that, when the mobile radio terminal device is left in an open state, a volume lower than the user-set volume is set, but separately from the processing shown in FIGS. The control unit 100 measures the duration of the state in which the housing is open, and controls the panel speaker 52 through the receiver 50 and the speaker control unit 51 when the housing is in an open state for a preset time or longer. A warning sound is generated to prevent the housing from being left open.

  As described above, in the mobile radio terminal having the above-described configuration, while the casing is open, during the outgoing call operation or immediately after the outgoing call operation is finished (elapsed time is less than n), when the outgoing call operation is interrupted, during playback of voice data When the user is highly likely to be listening to the receiver 50 or the panel speaker 52, the hearing protection volume is set and the ringtone, key operation confirmation sound and warning sound are output loudly. If the operation state is not in the above state even when the housing is open, the ring tone, key operation confirmation sound, and warning sound are output at a maximum limit volume.

  Therefore, according to the mobile radio terminal device having the above-described configuration, even when the housing is open, the sound is not uniformly reduced. However, the user can recognize the generation of the notification sound and is less likely to lose the necessary opportunity.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. Further, for example, a configuration in which some components are deleted from all the components shown in the embodiment is also conceivable. Furthermore, you may combine suitably the component described in different embodiment.

  For example, in the above-described embodiment, the operation has been described by way of example in a situation where a ringtone, a key operation confirmation sound, and a warning sound are output loudly. However, the present invention can also be applied to other situations. An example thereof is shown in FIGS.

  In this case, when the controller 100 emits a sound as shown in FIGS. 5 and 6, the controller 100 emits a sound based on the parameter table as shown in this table. This parameter table is stored in the memory 70.

  This volume table corresponds to various situations with a preset volume depending on whether the casing of the mobile radio terminal device is in a closed state (closed state) or in an open state (open state). This is for outputting loud sounds. In FIG. 5 and FIG. 6, the item “(when opened)” does not matter whether the casing is open or closed.

  In the above embodiment, although referred to as hearing protection volume, the hearing protection volume parameter may be set intentionally larger than the Max limit volume parameter. In this case, there is a high possibility that the user is in the vicinity with the case opened, such as during a transmission operation or immediately after a transmission operation (elapsed time is less than n), when the transmission operation is interrupted, or during playback of audio data. In case of situation, call with loud sound. On the other hand, if the operation state is not in the above state even when the housing is opened, that is, when it is highly likely that the user is not in the surroundings, the above hearing protection The ringing tone, the key operation confirmation sound, and the warning sound can be loudly output at a Max restricted volume that is smaller than the volume, so as not to disturb the surroundings.

  Further, in the above embodiment, the description has been given on the assumption that the receiver 50 and the panel speaker 52 simultaneously output loudspeakers. However, the loudspeaker can selectively output loudspeakers according to the situation, or one of them depending on the situation. The loudspeaker may be output from the voice, or the voice may be output from both.

  For example, when a loud sound is output at a user-set volume (when closed), a loud sound is output from the panel speaker 52, while when a loud sound is output at a Max restricted volume or a hearing protection volume (when opened). Is output from the receiver 50.

  Alternatively, when the loudspeaking output is performed at the Max restricted volume (when it is unlikely that the user is hitting the ear), the loudspeaking output is performed from the panel speaker 52, while the loudspeaking output is performed at the hearing protection volume (when the user When there is a high possibility that it is touching the ear), the loudspeaker output is made from the receiver 50.

  Also, for example, when a loud sound is output at a user-set volume (when closed), a loud sound is simultaneously output from the receiver 50 and the panel speaker 52, while a loud sound is output at a Max restricted volume or a hearing protection volume (open). In the case of the above state), the loudspeaker is output only from the receiver 50.

  Alternatively, when the loudspeak output is performed at the Max restricted volume (when it is unlikely that the user is hitting the ear), the loudspeaker is simultaneously output from the receiver 50 and the panel speaker 52, while the loudspeaker is output at the hearing protection volume. In such a case (when the user is highly likely to be wearing the ear), the loudspeaker is output only from the receiver 50.

In the above-described embodiment, the description has been given on the assumption that the receiver 50 and the panel speaker 52 simultaneously output loudspeakers. However, the control unit 100 uses either one according to the user's request and the panel speaker 52 is used. Only the process shown in FIGS. 2 to 4 may be executed.
In addition, it goes without saying that the present invention can be similarly implemented even if various modifications are made without departing from the gist of the present invention.
