Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a volume control device mounted on an audio terminal device and performing volume control.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, mobile phones do not bother others when receiving telephone calls or e-mails in places where there are a large number of people, such as in a train, or in places that should be quiet, such as in a theater. So manner mode is prepared.
[0003]
In general, when the mobile phone is set to the manner mode, the ring tone of the mobile phone is turned off, and instead of the ring tone, the mobile phone itself vibrates with the incoming call, and also, it is possible to talk even with a small voice. The sensitivity of the microphone of the mobile phone can be increased. The manner mode is set by a manual operation of the user.
[0004]
[Problems to be solved by the invention]
However, in the above-described conventional mobile phone, if the user forgets to set the manner mode, a ringtone sounds when a call or e-mail is received, or a loud call is made, which makes the surrounding people uncomfortable. There was a problem that would be.
[0005]
Also, like a mobile phone, a portable music player (for example, an MP3 player, etc.) becomes so enthusiastic about the music that the user himself loses his or her attention to the sound leaking from the headphones. There was a problem that it made us feel uncomfortable.
[0006]
Therefore, an object of the present invention is to provide a volume control device and a program that can appropriately adjust the volume or input sensitivity of a voice terminal device in accordance with the surrounding environment in order to solve the above problems. .
[0007]
[Means for Solving the Problems]
An invention according to claim 1 for achieving the above object is a volume control device mounted on a voice terminal device for outputting voice and controlling a volume of the voice terminal device, wherein the volume control device is located within a predetermined range. Detecting means for detecting an external device to perform, based on a detection result of the detecting means, determining whether volume adjustment of the audio terminal device is necessary, and determining that volume adjustment is necessary, determining a volume of the audio terminal device. And control means for performing volume control for adjusting the volume.
[0008]
In the volume control device configured as described above, the detection unit detects an external device existing within a predetermined range, and the control unit determines whether the volume adjustment of the audio terminal device is necessary based on the detection result of the detection unit. Is determined, and if it is determined that volume control is necessary, the volume of the voice terminal device is adjusted.
[0009]
Then, for example, the detection unit is set to detect a mobile phone or a portable music playback device that has become widespread in recent years, and when the detection unit detects these external devices, the volume of the audio terminal device is reduced, Alternatively, if the control means is set to be turned off, the volume of the voice terminal device can be reduced or turned off in an environment where there are people around. As a result, it is possible to reliably prevent the surrounding people from feeling uncomfortable due to the volume of the audio terminal device.
[0010]
That is, according to the present invention, it is possible to appropriately adjust the volume of the audio terminal device according to the surrounding environment.
According to a second aspect of the present invention, there is provided a volume control device mounted on a voice terminal device for inputting voice and controlling an input sensitivity of the voice terminal device, wherein the volume control device detects an external device present in a predetermined range. Detecting means for determining whether the input sensitivity of the voice terminal device needs to be adjusted based on the detection result of the detecting means, and determining that the input sensitivity needs to be adjusted, the input sensitivity of the voice terminal device is determined. And control means for performing volume control for adjustment.
[0011]
In the volume control device configured as described above, the detecting means detects an external device present within a predetermined range, and the control means adjusts the input sensitivity of the voice terminal device based on the detection result of the detecting means. If the necessity is determined and it is determined that the input sensitivity needs to be adjusted, the input sensitivity of the voice terminal device is adjusted.
[0012]
Then, similarly to the first aspect of the present invention, the detecting means is set to detect a mobile phone or a portable music reproducing apparatus, and when the detecting means detects these external devices, the input sensitivity of the voice terminal apparatus is set. If the control means is set to amplify the input signal, the input sensitivity of the voice terminal device can be amplified in an environment where a human is present in the surroundings. As a result, it is possible to reliably input the voice to the voice terminal device even in an environment where only a small voice can be used so as not to make the surrounding people uncomfortable.
[0013]
That is, according to the present invention, the input sensitivity of the audio terminal device can be appropriately adjusted according to the surrounding environment.
Here, the control means may be set so as to exclude the external device designated in advance from the determination target.
[0014]
In this case, for example, if an external device fixed in an office or the like is specified in advance, even if the detecting unit detects the fixed external device instead of the external device carried by a human, the control unit will It is possible to prevent volume control of the audio terminal device. In addition, for example, if an external device installed in a home or a portable external device owned by a family is specified in advance, it is not always necessary to control the volume as in a home. In spite of this, it is possible to prevent the control means from adjusting the volume of the voice terminal device or amplifying the input sensitivity.
[0015]
That is, according to the present invention, the volume control of the audio terminal device can be performed according to the surrounding environment more appropriately.
The control means may be configured to count the number of the external devices detected by the detection means and to perform the volume control when the number of the external devices reaches a predetermined value. It may be.
[0016]
In this case, the control means may adjust the volume of the voice terminal device or amplify the input sensitivity in an environment where it is considered that there are only a few external devices and only a few people around. Can be prevented. That is, the same effect as the third aspect can be obtained.
[0017]
The control means may be set to operate at a predetermined timing.
That is, each time a predetermined timing (for example, a predetermined time interval) arrives, the volume control of the voice terminal device can be performed only when necessary.
[0018]
Specifically, when the audio terminal device is a mobile phone, for example, at least one of an incoming call and an outgoing call may be set as the timing.
Further, when the audio terminal device comprises a portable music reproducing device, for example, the time when an operation signal is detected or the time when a transition of music is detected during music reproduction is determined as described in claim 7. The timing should be good.
[0019]
Here, the detecting means includes a wireless network establishing means for establishing a wireless network by wirelessly communicating with the external device, and via the wireless network established by the wireless network establishing means. The communication device may be configured to detect the communicable external device.
[0020]
The wireless communication between the wireless network constructing means and the external device may be performed based on, for example, the Bluetooth (registered trademark) standard.
That is, since devices that perform wireless communication based on the Bluetooth (registered trademark) standard are widely used, the present invention can be easily applied.
[0021]
In addition, in the Bluetooth (registered trademark) standard, since the communication distance is set short (about 10 m), it is possible to detect even a remote external device and control the volume control of the voice terminal device.
In this case, it is preferable that the control unit handles the external device having a specific profile among the external devices detected by the detection unit as a determination target, and performs the volume control.
[0022]
That is, in the Bluetooth (registered trademark) standard, various profiles defining the specifications such as a communication protocol and a user interface are prepared according to an application to which the Bluetooth (registered trademark) standard is applied, and therefore, the profile is installed in an external device. The type of the external device can be specified by identifying the type of the profile being performed.
[0023]
An external device equipped with an intercom profile (Intercom Profile) for implementing one-to-one wireless communication and a headset profile (Headset Profile) for implementing voice data transmission has a wireless communication function. Therefore, the volume control of the audio terminal device can be performed only when the mobile phone or the portable music reproducing device is detected.
[0024]
Each of the means constituting the volume control device according to any one of claims 1 to 10 may be configured as a program for causing a computer to function as described in claim 11.
In this case, the program is stored in a computer-readable recording medium such as an FD, MO, DVD, CD-ROM, hard disk, or memory card, and the stored program is loaded into a computer system as needed. It can be used by starting. Alternatively, the program may be recorded on a ROM or a backup RAM as a computer-readable recording medium, and the ROM or the backup RAM may be incorporated in a computer system and used. Further, the program is not limited to the one recorded on the recording medium, and may be used by loading and starting via a network.
[0025]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[First Embodiment]
First, FIG. 1 is a block diagram showing an internal configuration of a mobile phone to which the present invention is applied.
[0026]
As shown in FIG. 1, the mobile phone 1 includes a liquid crystal display or the like, a display unit 12 for displaying a telephone number, the contents of an e-mail, and the like, a button switch, and the like, for operating the mobile phone 1. , A ringtone output unit 14 for outputting a ringtone, a voice output unit 15 for converting voice data into voice and outputting the voice, a microphone for inputting voice, and the like. A voice input unit 16 for converting voice into voice data, a vibration generating unit 17 including a vibration motor for vibrating the mobile phone 1, a transmission / reception unit 18 for modulating / demodulating data based on a communication standard of a mobile phone network, A communication module 19 that modulates and demodulates data based on the Bluetooth (registered trademark) standard, and a communication module 19 that modulates and demodulates data based on the mobile phone network communication standard and the Bluetooth (registered trademark) standard. The CPU 10 controls the receiving unit 18 and the communication module 19, generates a packet, and controls each unit of the mobile phone 1 in response to sending or receiving a telephone call or an electronic mail. The memory 11 includes a ROM and a RAM that store data to be used and supply them to the CPU 10 as necessary.
[0027]
However, the ringtone output unit 14 and the vibration generation unit 17 are configured to operate the ringtone and the vibration motor in accordance with an instruction from the CPU 10. The voice input unit 16 is configured so that the sensitivity of the microphone can be adjusted in two stages according to an instruction from the CPU 10.
[0028]
The mobile phone 1 is configured to function as a so-called Bluetooth (registered trademark) communication terminal device by the CPU 10 and the communication module 19. The mobile phone 1 is equipped with an intercom profile for realizing a one-to-one wireless communication, and can perform wireless communication with a Bluetooth (registered trademark) communication terminal device having the intercom profile. I have.
[0029]
That is, the mobile phone 1 has a form in which a Bluetooth (registered trademark) communication terminal device is provided in a normal mobile phone.
Here, the CPU 10 has a function of setting and canceling at least the manner mode, in addition to the outgoing call processing and incoming call processing of telephones and e-mails.
[0030]
First, in the transmission process, when a telephone transmission command is input via the operation unit 13, the CPU 10 controls the transmission / reception unit 18 based on the communication standard of the mobile phone network, and controls the mobile phone via the mobile phone network. Establish a call between 1 and the destination. Then, the audio data from the audio input unit 16 is transmitted to the destination via the transmission / reception unit 18, the audio data received by the transmission / reception unit 18 is output to the audio output unit 15, and A request to display the input destination telephone number is made to the display unit 12. If an e-mail transmission command is input, the e-mail server accesses the mail server via the transmission / reception unit 18 and transmits the e-mail to the mail server.
[0031]
In the incoming call process, the CPU 10 first makes a request to display the telephone number and mail address of the caller to the display unit 12 and makes an operation request to the ring tone output unit 14 and the vibration generation unit 17 to issue a request to the user. Notify you of incoming calls and e-mails. When a command for receiving a telephone call or an e-mail is input via the operation unit 13, the transmission / reception unit 18 is controlled to establish a call with the transmission source via the mobile phone network or to access the mail server. And receive an email.
[0032]
Then, in the manner mode setting process, the CPU 10 prohibits the ring tone output unit 14 from outputting a ring tone, and issues an operation request to the vibration generation unit 17 when a telephone call or an e-mail is received. Further, it requests the audio input unit 16 to amplify the sensitivity of the microphone. When canceling the manner mode, the ring tone output unit 14 is released from the prohibition of the ring tone, and the voice input unit 14 is requested to return the microphone sensitivity to the original level.
[0033]
Note that the CPU 10 performs a manner mode confirmation process which is performed as a pre-process when performing the outgoing process and the incoming process. The flow of the manner mode checking process will be described with reference to the flowcharts shown in FIGS.
First, FIG. 2 is a flowchart showing the flow of the manner mode checking process.
[0034]
As shown in FIG. 2, the CPU 10 detects a call or an e-mail transmission request via the operation unit 13 or detects an incoming call or e-mail based on a signal demodulated by the transmission / reception unit 18. Is started, the CPU 10 first checks whether or not the mobile phone 1 is set to the manner mode (S110). Then, when it is confirmed that the manner mode is not set (No: S110), a manner mode determination process for determining whether to set the manner mode is performed (S120). Here, when the result of the manner mode determination processing is the manner mode setting (Yes: S130), the CPU 10 executes the manner mode setting processing (S140). In S110, if the mobile phone 1 has already been set to the manner mode (Yes: S110), or if the result of the manner mode determination processing indicates that the manner mode is not set in S130 (No: S130). Then, the CPU 10 ends this processing while maintaining the current setting.
[0035]
Here, FIG. 3 is a flowchart showing the flow of the manner mode determination process (S120).
As shown in FIG. 3, when the manner mode determination process is started, the CPU 10 first determines whether or not there is an external device performing wireless communication based on the Bluetooth (registered trademark) standard around the mobile phone 1. An IQ packet to be confirmed is broadcast for a predetermined time (S210).
[0036]
When an FHS packet indicating information such as the type and address of the external device is received from the external device and it is confirmed that an external device is present in the surroundings (Yes: S220), an ID packet for calling a specific external device is output to the external device. Of the external device, and confirms what profile the external device is equipped with from the FHS packet that is the response (S230). Here, if it is confirmed that the external device does not have a headset profile (hereinafter, referred to as “target profile”) for realizing the intercom profile and the transmission of the audio data (No: S240), the CPU 10 Checks whether all the external devices responding to the broadcast have been checked (S250). If it is confirmed that all the external devices have not been checked, the process returns to S230, where an ID packet is transmitted to one of the unchecked external devices, and the process proceeds to S240. Confirm that the target profile is mounted on any of the external devices, or repeat S230 and S240 until all the external devices are checked, and confirm that the target profile is not mounted on all the external devices. In this case, the manner mode non-setting is determined as the determination result (S260), and the process ends.
[0037]
If it is determined in S240 that the external device is loaded with the target profile, the CPU 10 determines that the manner mode is set (S270), and ends the process.
Here, if no FHS packet is received from the external device in S220, it is determined that there is no external device, and the process proceeds to S260, followed by terminating the present process.
[0038]
According to the mobile phone 1 configured as described above, even if the user forgets to set the mobile phone 1 to the manner mode, the Bluetooth (registered trademark) communication terminal device is provided around the user. If there is a person carrying a mobile phone or a portable music player, the manner mode is automatically set.
[0039]
For this reason, in an environment where there is another person in the vicinity, it is possible to prevent a ringtone of a telephone call or an e-mail from sounding, or a conversation with a caller with a loud voice to make the surroundings uncomfortable.
In addition, the manner mode confirmation processing is started when a telephone call requiring a manner mode setting or when a telephone call or an e-mail is received, so that the processing load of the CPU 10 can be reduced.
[0040]
In addition, since mobile phones that perform wireless communication based on the Bluetooth (registered trademark) standard are widely used, the present invention can be easily applied. Moreover, according to the Bluetooth (registered trademark) standard, the communication distance is set to about 10 m, so that it is possible to prevent the CPU 10 from detecting even a remote external device and setting the mobile phone 1 to the manner mode.
[0041]
Also, when an external device equipped with an intercom profile or a headset profile (or another profile may be used if a profile is installed in a mobile phone or a portable music player), is detected. Only when the mobile phone 1 is set to the manner mode, the manner mode is set even when an external device capable of wireless communication based on the Bluetooth (registered trademark) standard other than the mobile phone and the portable music playback device is detected. The manner mode is set in an appropriate environment without being set.
[0042]
In the present embodiment, the CPU 10 and the communication modules 19, S210, and S220 correspond to the detecting means of the present invention, and the CPU 10 and S110 to S140 and S230 to S270 correspond to the controlling means of the present invention.
Further, the CPU 10 and the communication module 19 correspond to a wireless network construction unit of the present invention.
[Second embodiment]
In this embodiment, the manner of determining the manner mode of the mobile phone 1 is different from that of the first embodiment, and the device configuration of the mobile phone 1 (see FIG. 1) is completely the same. Therefore, here, only the manner mode determination processing will be described in detail, and description of the same processing as in the first embodiment will be omitted.
[0043]
First, in the present embodiment, the mobile phone 1 has a configuration in which the specified number of external devices necessary for setting the manner mode is preset in the memory 11 and the detected number of external devices is equal to or more than the specified number. The manner mode is set.
Here, FIG. 4 is a flowchart illustrating a flow of the manner mode determination process in the present embodiment.
[0044]
As shown in FIG. 4, when the process is started, the CPU 10 broadcasts an IQ packet for a certain period of time, and an external device that performs wireless communication based on the Bluetooth (registered trademark) standard exists around the mobile phone 1. It is confirmed whether or not (S310). Then, when the FHS packet is received from the external device and it is confirmed that the external device is present in the surroundings (Yes: S320), the number of responding external devices is counted (S330). Here, when it is confirmed that the number of the external devices has reached the specified number set in the memory 11 (Yes: S340), the manner mode setting is determined as a determination result (S350), and the present process ends.
[0045]
Here, if no FHS packet is received from the external device in S320 (No: S320), or if the number of external devices does not reach the specified number in S340 (No: S340), the manner mode non-setting is set. As a result of the determination (S360), the present process ends.
[0046]
According to the mobile phone 1 of the present embodiment, the mobile phone 1 is set in the manner mode even in an environment where there are only a few external devices and only a few people are present in the environment. Can be prevented.
In the present embodiment, the CPU 10 and S310 and S320 correspond to the detection unit of the invention, and the CPU 10 and S320 to S360 correspond to the control unit of the invention.
[Third embodiment]
In the present embodiment, a new process is added to the mobile phone 1 of the first embodiment, and the manner of determining the manner mode is partially different, but the device configuration of the mobile phone 1 (see FIG. 1) is completely the same. is there. Therefore, here, only the newly added processing and the manner mode determination processing will be described in detail, and the description of the same processing as in the first embodiment will be omitted.
[0047]
First, in the present embodiment, the mobile phone 1 includes a database for registering the IDs of the external devices individually in the memory 11, and the IDs of the external devices are registered in this database in advance. In the manner mode determination process, even if an external device registered in the database responds, the profile of the external device is not checked.
[0048]
Here, FIG. 5 is a flowchart illustrating a flow of the external device registration process performed by the CPU 10 of the mobile phone 1 in the present embodiment.
As shown in FIG. 5, when the process is started, the CPU 10 first broadcasts an IQ packet around the mobile phone 1 for a certain period of time (S410), and performs wireless communication based on the Bluetooth (registered trademark) standard. It is determined whether an external device is present around the mobile phone 1 (S420). When an FHS packet is received from a surrounding external device and it is confirmed that the external device is present (Yes: S420), an ID packet is transmitted to one of the external devices, and an external It is confirmed what kind of profile the device has (S430). Here, when the external device confirms that the target profile is installed (Yes: S440), the CPU 10 confirms whether or not the ID of the external device is already registered in the database of the memory 11 (S450). If it is confirmed that the external device has not been registered (No: S450), the ID of the external device is registered in the database (S460).
[0049]
Then, it is confirmed whether or not all the external devices that have responded have been checked (S470). If it is confirmed that all the external devices have not been checked (No: S470), the process returns to S430. The above process is repeated for the external devices that have not been checked.
[0050]
Note that, in S440, it is confirmed that the target profile is not mounted on the external device (No: S440), or in S450, it is confirmed that the ID of the external device is already registered in the database (Yes). : S450), the CPU 10 returns the process to S430, and confirms the installed profile for the unchecked external device.
[0051]
After confirming that all the external devices have been checked through such processing (Yes: S470), the CPU 10 ends this processing.
If no FHS packet has been received in S420 (No: S420), this process is immediately terminated.
[0052]
FIG. 6 is a flowchart illustrating a flow of a manner mode determination process performed by the CPU 10 of the mobile phone 1 in the present embodiment. As shown in FIG. 6, when the process is started, the CPU 10 broadcasts an IQ packet for a certain period of time, and an external device that performs wireless communication based on the Bluetooth (registered trademark) standard exists around the mobile phone 1. It is confirmed whether or not (S510).
[0053]
When receiving the FHS packet from the external device and confirming that the external device is present in the surroundings (Yes: S520), the CPU 10 checks one of the received FHS packets, and checks the external device included in the FHS packet. It is confirmed whether the ID is registered in the database of the memory 11 (S530). Here, when it is confirmed that there is no corresponding ID in the database (No: S530), the CPU 10 transmits the ID packet to the external device that has transmitted the FHS packet, and confirms the profile mounted on the external device. Perform (S540). Then, when it is confirmed that the external device does not have the target profile (No: S550), the CPU 10 confirms whether or not all the external devices responding to the broadcast have been checked (S560).
[0054]
If it is confirmed that all the external devices have not been checked (No: S560), the process returns to S530, where one of the unchecked FHS packets is selected, and the ID included in the FHS packet is selected. Is registered in the database (S530), and the process moves to S550. In S530, if it is confirmed that the corresponding ID is registered in the database (Yes: S530), the CPU 10 proceeds to S560.
[0055]
After confirming that all the external devices have been checked through such processing (Yes: S560), the CPU 10 determines that the manner mode is not set (S570), and ends the processing.
If no FHS packet is received from the external device in S520 (No: S520), the CPU 10 determines that there is no external device, shifts the processing to S570, and ends this processing.
[0056]
If it is determined in S550 that the external device has the target profile (Yes: S550), the CPU 10 determines that the manner mode is set (S580), and ends this processing.
According to the mobile phone of the present embodiment configured as described above, as shown in FIG. 7, the wireless communication area of the mobile phone 1 (portion surrounded by a broken line in the figure) is based on the Bluetooth (registered trademark) standard. Even if there are a variety of external devices that perform wireless communication with each other, if the ID of an external device that is not the target of the manner mode determination process is registered in advance, the manner mode may not necessarily be set. Regardless, it is possible to prevent the mobile phone 1 from being set to the manner mode.
[0057]
In the present embodiment, the CPU 10 and S510 and S520 correspond to the detection unit of the present invention, and the CPU 10 and S530 to S580 correspond to the control unit of the present invention. As described above, the embodiments of the present invention have been described, but the present invention is not limited to the above embodiments, and it goes without saying that various forms can be adopted as long as they belong to the technical scope of the present invention. .
[0058]
For example, in the second embodiment, when the number of detected external devices reaches the specified number, the determination result is set to the manner mode. However, the ID of the external device is registered in the database in advance as in the third embodiment. In addition, the manner mode determination processing may be set so that the external device registered in the database is not counted. If the number of external devices does not reach the specified number, the profile of the responding external device is checked, and if at least one of the external devices has the target profile, the determination result is set to the manner mode. May be set to a manner mode determination process.
[0059]
Further, in the above embodiment, the mobile phone 1 performs processing such as confirmation and determination of the manner mode at the time of receiving a telephone call or e-mail or at the time of making a telephone call. The mobile phone 1 may be set to start checking or determining the mode.
[0060]
In this case, the process may proceed to a manner mode setting process after a manner mode confirmation process as shown in FIG.
That is, as shown in FIG. 8, when an IQ packet is received from an external device (S610), an FHS packet is transmitted and a response is made (S620). Then, an ID packet is transmitted to the external device, and an inquiry about a profile mounted on the external device is made (S630). After receiving the FHS packet from the external device (S640) and confirming that the external device has the target profile, the process proceeds to a manner mode setting process (S650).
[0061]
Further, in the above embodiment, the present invention is applied to a mobile phone, but the present invention may be applied to, for example, a portable music playback device provided with a Bluetooth (registered trademark) communication terminal device.
In this case, the process may proceed to the manner mode setting process through the process shown in FIG.
[0062]
That is, when an operation signal from a remote controller or the like operating the music reproducing device is detected (S710), an IQ packet is broadcast (S720). When the FHS packet is received from the external device (S730), an ID packet is transmitted to inquire about the profile mounted on the external device (S740). The FHS packet is received again from the external device (S750), the profile installed is confirmed, and if the external device has the target profile, the manner mode setting process such as reducing the volume of the headphones is performed. (S760). Note that, in addition to the detection of the operation signal, the above process may be started at the time of detecting a transition of music during music reproduction.
[0063]
In the above-described embodiment, the mobile phone 1 performs wireless communication with an external device based on the Bluetooth (registered trademark) standard to detect the external device. However, for example, the universal plug and play (UPnP) ) May be used to detect an external device.
[0064]
In the above-described embodiment, the programs for the processes performed by the CPU 10, such as the manner mode determination process, are stored in the memory 11 including the ROM and the RAM. For example, the FD, MO, DVD, CD-ROM, hard disk, memory card Or the like, and may be stored in a computer-readable recording medium, and the stored program may be loaded into the CPU 10 as needed.
