JP-A-4-81156 JP 2000-125027 A Japanese Patent Laid-Open No. 5-130181

  However, in the cordless telephone device described in Patent Document 3, since the “mute” signal is transmitted to the acoustic device, not only the volume from the acoustic device is lowered but also the sound is muted. If there is only one person who enjoys the audio device when there is an incoming call to the telephone device, that person will appear at the incoming phone device, so there is no problem even if the sound from the audio device is muted. However, if someone else enjoys the sound from the audio equipment together with the user of the telephone device, if the sound from the audio equipment is suddenly muted, if the audio equipment is a television or radio, a corner program You will miss it.

  Then, when the call is finished, it is assumed that the user feels awkward because he gives up with the user of the telephone device or becomes a source of ugliness.

  Therefore, the present invention provides a telephone device and a remote operation method for the audio device that can reliably recognize that an incoming call has been received and can prevent trouble even if a person who enjoys the audio device is other than the user. With the goal.

  The present invention relates to a telephone device having a function of remotely operating an audio device, measuring a volume by inputting a surrounding sound received from a microphone, and if the surrounding sound is equal to or higher than a predetermined volume, A notification of a remote operation that lowers the audio output is transmitted to the acoustic device.

  Even if the sound output of the audio equipment is reduced to such an extent that the ringtone can be heard, the present invention can ensure that the volume is high enough for anyone other than the user of the telephone device to enjoy the audio equipment. Even if the person who enjoys the audio equipment is other than the user, the trouble can be prevented.

  According to a first aspect of the present invention, in a telephone device having a function of remotely controlling an audio device, a speaker for outputting a ring tone, a microphone for inputting a sound, and a surrounding sound being received from the microphone to input a volume. When the sound is measured and the surrounding sound is equal to or higher than a predetermined volume, the controller includes a control unit that transmits a sound reduction notification for reducing the sound output of the audio apparatus to a predetermined volume.

  When there is an incoming call, a ring tone for notifying the incoming call is emitted from the speaker. When the volume of the audio device is high, the ring tone may not be heard by the user of the telephone device. The control unit measures the surrounding volume of the incoming call input by the microphone. Since the ambient sound includes sound from the acoustic device, when the sound from the acoustic device is loud, the ambient sound input by the microphone increases according to the volume of the sound. The control unit compares the surrounding volume, which is so large that the ring tone cannot be heard, with the volume measured as the predetermined volume. As a result of the comparison, when the surrounding sound is larger than the predetermined volume, the control unit transmits a sound reduction notification for reducing the sound output of the acoustic device to the acoustic device. The audio device that has received the remote operation notification that reduces the audio output decreases the volume by the volume set by the sound reduction notification. To enjoy the audio equipment, the sound is listened with a certain level of volume increase, so if the sound volume is lowered due to several sound reduction notifications, the sound is not muted. Therefore, even if the sound output of the acoustic device is reduced to such an extent that the ringtone can be heard, a sound volume that can be enjoyed by a person other than the user of the telephone device can be secured.

  The second invention of the present application is characterized in that the control unit measures the volume during an incoming call while the ringtone is not ringing.

  When the control unit inputs an ambient sound during an incoming call and measures the volume, if the incoming sound for notifying an incoming call is ringing from the speaker, the incoming sound is superimposed on the surrounding sound and input from the microphone. Then, the volume is as loud as the ringtone. Therefore, the control unit can measure the volume during the incoming call while the ringtone is not ringing, and can measure the volume from the acoustic device in a state where the ringtone is not superimposed on the surrounding sound. .

  The third aspect of the present invention is characterized in that the control unit cancels the ringtone from the input surrounding sound when the volume of the incoming call is measured while the ringtone is ringing.

  When the control unit inputs an ambient sound during an incoming call and measures the volume, if the incoming sound for notifying an incoming call is ringing from the speaker, the incoming sound is superimposed on the surrounding sound and input from the microphone. Then, the volume is as loud as the ringtone. Therefore, the control unit cancels the ringtone from the input ambient sound when measuring the volume of the incoming call while the ringtone is ringing. By doing so, it is possible to cancel the ring tone that is superimposed on the surrounding sound, so that the ring tone is not superimposed on the surrounding sound.

  According to a fourth aspect of the present invention, the control unit stores the number of times the sound reduction notification is transmitted, and the sound equipment is transmitted as many times as the number of times the sound reduction notification is transmitted when the call ends or when the incoming call stops. This is characterized in that a notification of an increase in sound that increases the sound output is transmitted to an acoustic device.

When the incoming call is received, the sound equipment is reduced by sending a notification to reduce the volume of the sound equipment. When the call ends or the incoming call stops, the telephone device user wants to enjoy the sound equipment again. It is. Therefore, the control unit stores the number of times that the sound reduction notification is transmitted, and when the call ends or the incoming call is interrupted, a sound increase notification that increases the sound output of the audio device by that number is sounded. By transmitting to the device, the user of the telephone device can bother returning to the state before using the telephone device without performing an operation of increasing the sound with the remote controller of the audio device.

  According to a fifth aspect of the present invention, in the acoustic device remote control method for a telephone device having a function of remotely controlling an acoustic device, the volume of the ambient sound during the incoming call is measured. The sound reduction notification for reducing the sound output is transmitted to the audio equipment.

  When the volume of the audio device is high, there is a case where the user who uses the telephone device cannot hear the ring tone for notifying the incoming call. In that case, first, the surrounding volume of the incoming call is measured. Since the ambient sound includes sound from the acoustic device, if the sound from the acoustic device is loud, the ambient sound increases according to the volume of the sound. Therefore, the sound volume is compared with the sound volume measured as a predetermined sound volume that is so high that the ring tone cannot be heard. As a result of the comparison, if the surrounding sound is larger than the predetermined volume, a sound reduction notification for reducing the sound output of the acoustic device is transmitted to the acoustic device. The audio device that has received the remote operation notification that reduces the sound output reduces the sound volume by the volume set by the sound reduction notification. To enjoy the audio equipment, the sound is listened with a certain level of volume increase, so if the sound volume is lowered due to several sound reduction notifications, the sound is not muted. Therefore, even if the sound output of the acoustic device is reduced to such an extent that the ringtone can be heard, a sound volume that can be enjoyed by a person other than the user of the telephone device can be secured.

  The sixth invention of the present application is characterized in that the volume during an incoming call is measured while the ringtone is not ringing.

  When a surrounding sound during an incoming call is input and the volume is measured, if the incoming sound for notifying an incoming call is ringing from the speaker, the incoming sound is superimposed on the surrounding sound. Then, the volume is as loud as the ringtone. Therefore, by measuring the volume during an incoming call while the ringtone is not ringing, the volume from the audio device can be measured in a state where the ringtone is not superimposed on the surrounding sound.

  The seventh invention of the present application is characterized in that when the ringing tone is measured while the ringing tone is ringing, the ringing tone is canceled from the input surrounding sounds.

  When measuring the volume by inputting surrounding sounds during an incoming call, if the incoming ring tone for notifying an incoming call is ringing, the incoming ring tone is superimposed on the surrounding sounds. Then, the volume is as loud as the ringtone. Therefore, the control unit cancels the ringtone from the surrounding sounds when measuring the volume of the incoming call while the ringtone is ringing. By doing so, it is possible to cancel the ring tone that is superimposed on the surrounding sound, so that the ring tone is not superimposed on the surrounding sound.

  The eighth invention of the present application stores the number of times the notification of sound reduction is transmitted, and outputs the sound output of the acoustic device for the number of times the notification of sound reduction is transmitted when the call ends or when the incoming call is interrupted. A notification of the remote operation to be raised is transmitted to the audio equipment.

  When the incoming call is received, the sound equipment is reduced by sending a notification to reduce the volume of the sound equipment. When the call ends or the incoming call stops, the telephone device user wants to enjoy the sound equipment again. It is. Therefore, when the call is terminated or the incoming call is interrupted, it is possible to bother the phone device by sending a sound increase notification that increases the sound output of the sound device by the number of times the sound reduction notification is transmitted. The user can return to the state before using the telephone device without performing an operation of increasing the sound with the remote controller of the audio device.

  The operation of the handset 3 of the cordless telephone device 1 which is an example of the telephone device according to the embodiment of the present invention configured as described above will be described with reference to FIGS. 4 and 5 are flowcharts for explaining the operation of the handset 3 of the cordless telephone device 1 which is an example of the telephone device according to the embodiment of the present invention. 6A to 9A are schematic front perspective views for explaining the operation of the handset of the cordless telephone device which is an example of the telephone device according to the embodiment of the present invention, and FIG. It is a back side schematic perspective view explaining operation | movement of the subunit | mobile_unit of an apparatus.

  Note that the flowcharts of FIGS. 4 and 5 illustrate operations performed when the control unit 18 detects an incoming call from the telephone line L. In the present embodiment, it is assumed that the ring tone is generated from the speaker 16 so as to repeat the period during which it is ringing and the period during which it is not ringing. Further, it is assumed that the television T is operated as an acoustic device that is remotely operated by the handset 3 of the cordless telephone device 1 according to the present embodiment.

  First, based on FIG. 4, the operation of detecting the volume of the television T by measuring the surrounding volume when the handset 3 is in the silent state of the ringtone will be described.

  As shown in FIG. 4, first, when the telephone control unit 18a of the control unit 18 detects an incoming call, it rings a ring tone once (S100). The ring tone is generated from the speaker 16 disposed on the back side of the handset 3 as shown in FIGS. 6 (A) and 6 (B).

  During the silent period when the ringtone is not ringing, the measurement unit 18c inputs ambient sounds from the microphone 11 (S110). Ambient sounds are input from the microphone 11 of the handset 3 as shown in FIGS. 7 (A) and 7 (B).

  Then, the measurement unit 18c compares the predetermined volume stored in the storage unit 18d in advance with the volume of surrounding sounds input in S110 (S120).

As a result of the comparison in S120, if the surrounding volume input from the microphone 11 is equal to or higher than the predetermined volume, the measurement unit 18c notifies the remote control unit 18b. Receiving the notification, the remote control control unit 18b transmits a sound reduction command for reducing the volume of the television T to the television T via the remote control transmission unit 15 as a sound reduction notification (S130). The sound reduction command is transmitted from the remote control transmission unit 15 of the child device 3 as shown in FIGS. 7 (A) and 7 (B).

  The sound reduction command is a command for adjusting the sound volume output from the television T step by step, and it is desirable to transmit two or three commands at a time if the sound is reduced step by step by one command. For example, when the volume of the TV T is excessive and only one sound reduction command is transmitted during a period when the ringtone is silent, the ringtone is used if the period during which the ringtone is silent does not become a considerable number of times. May not be heard by the person. If this happens, the caller will not be off-hook even though the ringtone has been sounded a considerable number of times, so that the caller may be mistaken for absence and may stop sending. By sending multiple sound reduction commands to the TV T at a time, the ring tone is generated several times so that the volume output from the TV T can be heard so that both the ring tone and the TV T sound can be heard. It is possible to reduce the sound.

  Then, the remote control control unit 18b stores the number of times the sound reduction command has been transmitted in the storage unit 18d, and proceeds to S150 (S140).

  If the measurement unit 18c compares the predetermined volume with the surrounding volume in S120 and determines that the surrounding volume is lower than the predetermined volume, the volume of the television T is sufficiently low and the user can hear the ringtone. If it is determined that it is, the process proceeds to S150.

  It is determined whether or not the telephone control unit 18a has pressed the F1 key 21a (S150). As shown in FIGS. 7A and 7B, the F1 key 21a functions as a call key for instructing the start of a call when pressed during an incoming call.

  If the F1 key 21a has not been pressed, the telephone control unit 18a determines whether an incoming call is still being received (S160). If it is determined in S160 that the call is still being received, the process returns to S100 and the process is repeated. In S160, when the incoming call is interrupted due to the reason that the caller interrupts the transmission, the process proceeds to S190.

  If it is detected in S150 that the F1 key 21a has been pressed, a call by the user is started (S170). Since the transmission of the sound reduction command in S130 is not performed when the call is started, the television T maintains the volume when the user starts the call.

  Then, the call ends (S180). As shown in FIGS. 8A and 8B, this call is terminated by pressing the F2 key 21b. That is, the F2 key 21b functions as a disconnect key that disconnects a call when pressed during a call.

  The remote controller control unit 18b transmits the sound increase command to the television T as many times as the cumulative number of times that the sound decrease command stored in S140 is transmitted (S190). The sound increase command is transmitted from the remote control transmitter 15 as shown in FIGS. 9 (A) and 9 (B).

  Thus, by measuring the volume of surrounding sounds during the period when the ringtone is silent, it is possible to accurately measure the volume of the surrounding audio equipment such as the television T, so that the ringtone can be heard. In addition, the volume of the television T can be gradually reduced.

When the handset 3 automatically sends a sound reduction command upon detection of an incoming call, the handset 3 sends the sound reduction command transmitted at the time of the incoming call when the call ends or when the incoming call is interrupted. Since the sound increase command is automatically transmitted to the television T for the cumulative number of times, the volume of the television T that has been reduced when the incoming call is received is automatically restored. Therefore, the user of the child device 3 can return to the state before use without performing the operation of increasing the sound with the remote control R of the television T.

  Next, the operation of the handset 3 of the cordless telephone apparatus 1 will be described with reference to FIG. 5. In FIG. 5, if the measurement is performed while the ring tone is ringing, the ring tone is canceled from the input surrounding sounds. Thus, an operation of detecting the volume level of the television T is shown.

  As shown in FIG. 5, when the telephone control unit 18a of the control unit 18 detects an incoming call, it rings a ringtone (S200). As shown in FIGS. 6 (A) and 6 (B), the ring tone is generated from the speaker 16 arranged on the back side of the handset 3.

  Then, the measurement unit 18c inputs ambient sounds from the microphone 11 (S210). At that time, if the telephone control unit 18a rings a ring tone, the measurement unit 18c cancels the surrounding sound input from the microphone 11 based on the ring tone stored in advance in the storage unit 18d. If the ring tone is not ringing, the input ambient sound is used as it is (S220). Ambient sounds are input from the microphone 11 of the handset 3 as shown in FIGS. 7 (A) and 7 (B).

  The cancellation of the ring tone may be canceled by the measurement unit 18c inputting the ring tone generated by the telephone control unit 18a from the telephone control unit 18a in real time from the input ambient sounds, or stored in advance in the storage unit 18d. You may make it cancel using the ringtone data which were made. The cancellation may be performed by decomposing the surrounding sound into frequency components and subtracting the frequency component of the ringtone from there to calculate the difference, or subtracting the volume of the entire ringtone from the volume of the entire surrounding sound. Thus, the difference may be calculated. The following is the same as S120 in FIG.

  In this way, if the ringtone is ringing, the volume of the television T included in the surrounding sound is measured by canceling the ringtone from the surrounding sound and canceling it. That is, the volume of the television T can be measured even when the ring tone is ringing or in a silent state. Therefore, even if the ringtone does not have a period of silence such as a melody, the TV T can be remotely operated according to the surrounding sound.

  Next, a method for operating the television T by operating the operation unit 12 of the handset 3 of the cordless telephone device 1 according to the embodiment of the present invention will be described with reference to FIGS. 10A is a diagram showing a display example of the standby state of the display unit of the cordless telephone device according to the embodiment of the present invention, and FIG. 10B is a display unit of the cordless phone device. FIG. 10C is a diagram showing the channel switching mode of the display unit of the cordless phone device. FIG. 11 (A) is a diagram showing a display example of a state during an incoming call on the display unit of the cordless telephone device according to the embodiment of the present invention, and FIG. 11 (B) is a diagram of the cordless phone device slave device. It is a figure which shows the channel switching mode of a display part. FIG. 12A is a diagram showing a display example of the standby state of the display unit of the cordless phone device according to the embodiment of the present invention, and FIG. 12B is a diagram of the cordless phone device slave device. FIG. 12C is a diagram showing a state during a call on the display unit, and FIG. 12C is a diagram showing a channel switching mode of the display unit of the cordless phone device.

  First, a method for remotely operating the television T when the handset 3 is in a standby state for incoming calls will be described with reference to FIG.

When “▽” at the bottom of the selection key 22 of the operation unit 12 is pressed from the standby screen shown in FIG. 10A, a menu screen as shown in FIG. 10B is displayed by the telephone control unit 18a. This menu screen includes “TV manufacturer registration” indicating a function of selecting and registering a manufacturer of the television T, “TV remote controller” indicating a function of operating the slave unit 3 as a remote controller of the television T, and a child connected to the master unit 2. This is a screen for selecting “extension of slave units” indicating a function for registering the change in the number of units 3. Further, guidance indicating the contents of the functions of the F1 key 21a and the F2 key 21b of the function key 21 is displayed on the lower side of the screen. In the menu mode in which this menu screen is displayed, when the F1 key 21a is pressed, the selection of the function at which the cursor whose display character is reversed is selected, and when the F2 key 21b is pressed, the return operation returns to the standby state.

  In this menu screen, the selection of the function is designated by moving the cursor that highlights the display character in the up-down direction by pressing “△” at the top of the selection key 22 or “▽” at the bottom. Then, as the guidance is displayed on the display unit 13, the selection is determined by pressing the F1 key 21 a of the function key 21. Here, a mode is set in which the slave unit 3 is made to function as a TV remote controller by pressing the lower part “▽” of the selection key 22 once to select “TV remote controller” and then pressing the F1 key 21a.

  When “TV remote control” is selected, the display screen of the display unit 13 shifts to a channel switching mode as shown in FIG. In this display screen, “TV remote control” indicating that the handset 3 is functioning as a remote control is displayed, and a function capable of switching channels by pressing one of the upper and lower selection keys 22 is displayed. “▼ ▲ Channel Switch” is displayed. For channel switching, a command for increasing the channel number is transmitted from the remote control control unit 18b via the remote control transmission unit 15 each time the upper part “Δ” of the selection key 22 is pressed. In addition, a command for decreasing the channel number is transmitted from the remote control transmission unit 15 every time the lower part “▽” of the selection key 22 is pressed. Each time the television T receives a command for switching those channels, the channel is switched by incrementing or decrementing the channel number one by one. If the selection key 22 is held down for a long time, a command for switching the channel is repeated and transmitted.

  In this channel switching mode, as shown in the guidance, pressing the F1 key 21a returns to the screen shown in FIG. Further, a remote operation for turning off the power of the television T is possible by pressing the F2 key 21b.

  In this way, when the handset 3 is on standby, the selection key 22 and the function key 21 can be operated to switch the channel of the television T or turn off the power.

  Next, a method of remotely operating the television T when the handset 3 is receiving a call or talking is described with reference to FIG.

  First, when receiving a call, the screen shown in FIG. 11A is displayed on the display unit 13. On this screen, one of the functions “Reject incoming call” and “TV remote control” can be selected. These functions specify selection by moving a cursor that highlights a display character in the vertical direction by pressing “△” above the selection key 22 or “▽” below the selection key 22. Here, as the guidance is displayed on the display unit 13, the selection is determined by pressing the F1 key 21 a of the function key 21. Here, a mode is set in which the slave unit 3 is made to function as a TV remote controller by pressing the lower part “▽” of the selection key 22 once to select “TV remote controller” and then pressing the F1 key 21a. When “TV remote control” is selected, the display screen of the display unit 13 shifts to a channel switching mode as shown in FIG. The function of the TV remote controller during an incoming call can be remotely operated by the same operation method as that described with reference to FIG.

  In this way, when the handset 3 is receiving a call, the selection key 22 and the function key 21 can be operated to switch the channel of the television T or turn off the power.

Next, when the call is in progress, the screen shown in FIG. Then, by pressing the F1 key 21a, the screen shown in FIG. 12B is displayed. On this screen, one of the functions “fax reception”, “TV remote control”, and “call recording” can be selected. These functions specify selection by moving a cursor that highlights a display character in the vertical direction by pressing “△” above the selection key 22 or “▽” below the selection key 22.

  Then, the F1 key 21a of the function key 21 is pressed to determine the selection. When “TV remote control” is selected, the display screen of the display unit 13 shifts to a channel switching mode as shown in FIG. The function of the TV remote controller during an incoming call can be remotely operated by the same operation method as that described with reference to FIG.

  In this way, even if the handset 3 is busy, the selection key 22 and the function key 21 can be operated to switch the channel of the television T or turn off the power.

  Further, the volume adjustment key 23 provided on the side surface of the slave unit 3 can be operated in any of a standby state, an incoming call, and a call state to transmit a sound increase command or a sound decrease command. Therefore, even in a standby state, during an incoming call, or during a call, the volume of the television T can be adjusted by increasing or decreasing. Similarly, the mute key 24 can transmit a mute command by operating in any of the standby state, the incoming call, and the call state. Therefore, the volume of the television T can be muted even in a standby state, during an incoming call, or during a call.

  The embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiment.
