Description

Mobile terminal call operation control system, control method, and control program

The present invention relates to control of a call operation of a mobile terminal, in particular, a call operation control system for a mobile terminal capable of accurately switching a call operation method of the mobile terminal according to a noise generation situation where the mobile terminal is placed, and control The present invention relates to a method and a program therefor.

For mobile terminals such as mobile phones and PDAs (Personal Digital Assistants), not only means for notifying the user of incoming calls and alarms, but also means for notifying them by sound, but also means for notifying by vibrator vibration (manner mode function) Is installed. By using this function, it is possible to notify the user of the occurrence of an incoming call, an alarm or the like without inconvenience caused by noise in the surroundings in principle. As a notification means for realizing the manner mode function, a call operation by vibration using a vibration motor is generally used. However, even if the mobile terminal is set to the manner mode, if the mobile terminal is placed on a hard object such as a wooden or steel desk and a ringing operation is performed by vibration, a loud vibration sound is generated. As a result, there is a problem of causing troubles due to noise in the surroundings.

Therefore, in order to solve such a problem, a technique is known in which the state of the mobile terminal is determined and the means for the call operation is determined according to the state (Patent Documents 1 to 5). ). Among these, in Patent Document 1, it is determined whether or not the mobile phone is in a moving state based on whether or not the acceleration value detected by the acceleration sensor exceeds a predetermined threshold, and the rotational speed of the vibrator motor is changed. Techniques for making them disclosed are disclosed.

Further, in Patent Document 2, a change in position of a mobile communication terminal is detected as vibration by a vibration detection unit, and a user of the terminal is in a stationary state, walking, or running depending on whether the detected vibration frequency is greater than a certain threshold value. The noise detection unit collects the sound around the mobile communication terminal as noise, and the user of the terminal can reduce the noise level depending on whether the collected noise level is greater than a certain threshold. Technology for realizing fine incoming notification control by determining whether the user is in high noise or under high noise and considering both the noise level and the frequency of the surrounding environment at the same time.

In Patent Document 3, the position of a mobile communication device is measured by a GPS sensor to detect a position measurement detection pattern (calculation of a moving speed, etc.), and the level of vibration generated around is measured by a vibration sensor. The vibration detection pattern is detected and recorded. When an incoming call is received, the movement state of the device user (“the user (driver) is traveling” “ Jogging "" Walking "" Still "" and a corresponding incoming call operation pattern is selected.

Further, Patent Document 4 detects and stores various vibrations such as the movement of the person when the user is holding the mobile phone, and whether the user holds the mobile phone when receiving an incoming call. There is disclosed a technique for determining whether or not to hold and notifying by vibration when it is determined that it is held.

Further, in Patent Document 5, the moving state of the mobile phone is detected by an acceleration sensor, the angle from the horizontal of the case of the mobile phone is detected by a geomagnetic sensor, and the stationary state is in a range where the tilt is equal to a preset tilt. A technique for notifying by means of visual appeal instead of vibration is disclosed.

However, in the technique disclosed in Patent Document 1, the number of rotations of the vibrator is set according to the moving state of the mobile phone or the like, so that the mobile phone or the like is placed on a hard object when it is stationary. Even if not, it will switch to a ringing operation that does not depend on vibration (lowering the number of revolutions) and cannot properly notify the user of the incoming call, or if the mobile phone etc. itself is in a moving state, Even when it is placed on a hard object, there is a drawback that it is switched to a call operation by vibration (increasing the number of rotations) and noise is generated in the surroundings.

Further, in the technique disclosed in Patent Document 2, since the current situation of the user is determined by the frequency generated in the mobile communication terminal according to the external situation and the incoming notification method is determined, Since the incoming call operation pattern is selected based on the moving speed of the communication device and the vibration pattern, the technique of Patent Document 4 determines whether or not the user holds a mobile phone when receiving an incoming call and determines the notification method. For this reason, the technique disclosed in Patent Document 5 has the same drawbacks as in Patent Document 1 in each case because the mobile phone moving state and the installation angle are determined to determine the notification method.

The present invention aims to prevent the occurrence of noise due to vibrator vibration in a portable terminal set in the manner mode.

[First Embodiment]
Hereinafter, a first embodiment of a call operation control system for a portable terminal according to the present invention will be described with reference to the accompanying drawings.
The call operation control system 1 of the present embodiment is a call operation control system for a mobile terminal that switches between a call operation of a mobile terminal caused by body vibration and a call operation of a mobile terminal other than the body vibration as a basic configuration.
A detector (12) that detects, as time-series data, a state in which the mobile terminal vibrates in response to vibration from a vibration source that performs a call operation of the mobile terminal due to the sensory vibration, and the detector (12) detects the Analyzing the characteristics of the time-series data, determining whether the mobile terminal generates a sound above a threshold based on vibration from the vibration source, and determining a noise generation state for outputting a switching signal for the call operation Means 13.
When the mobile terminal is vibrated by bodily sensation vibration to inform the user that there is an incoming call to the mobile terminal, if the user wears the mobile terminal, the user can experience the vibration generated in the mobile terminal. You can know incoming calls without disturbing others.
However, when the user places the mobile terminal away from the user, for example, on the desk, the vibration generated in the mobile terminal at the time of incoming call is repelled without being absorbed by the desk, so the desk acts like a diaphragm of a speaker. Then, a sound exceeding the threshold is generated based on the vibration generated in the mobile terminal, and this sound is perceived as noise by the user and others, which causes trouble for others. For example, when a portable terminal is placed on a futon, the vibration energy of the portable terminal is absorbed by the futon, so it is impossible to vibrate a soft futon to the audible sound level as a result of absorbing the vibration energy. No noise is generated.
For this reason, in order to detect whether or not it is in a state of generating noise when the user places the mobile terminal away from the mobile terminal, for example, on a desk or futon, the other party placing the mobile terminal vibrates. There are a case where it is detected whether or not noise is likely to be generated and a case where it is detected whether or not noise is actually generated.
The first embodiment of the present invention shown in FIG. 1 realizes a configuration for detecting whether or not the other party who places the mobile terminal is likely to generate vibration. The mobile terminal shown in FIG. The call operation control system 1 is centered on a call operation control means 14 for controlling the call operation, and is electrically connected to the call operation control means 14 and requests a start of the call operation when an incoming call is received. 111, a noise generation state determination means 13 for determining whether or not the call operation is in a state of generating noise, a vibration source control means 15A for controlling the vibration source in accordance with an instruction from the control means 14, and the control means 14 The sound source control means 16A for controlling the sound source according to the instruction, the light source control means 17A for controlling the light source according to the instruction of the control means 14 and the noise generation state determination means 13 are connected. The acceleration sensor 12 for measuring the acceleration due to the vibration of the mobile terminal, the vibration source 15B connected to the vibration source control means 15A and generating vibration according to the instruction from the means 15A, and the sound source control means 16A connected to the sound source control means 16A The sound source 16B that generates sound according to the instructions of the above and the light source 17B that is connected to the light source control means 17A and generates light according to the instructions from the means 17A.

The call request unit 11 is based on an event such as an incoming call to the mobile terminal or an alarm issued from the mobile terminal, in order to notify the surroundings, especially users of the mobile terminal, that these events have occurred in the mobile terminal. Then, a signal for requesting the start of the call operation is output to the call operation control means 14.

The acceleration sensor 12 is a sensor mounted on the portable terminal, and senses the movement of the portable terminal and measures the change in the speed of the terminal, that is, the acceleration of the portable terminal. Specifically, for example, when the call operation of the mobile terminal is set to the call by vibration instead of the call by sound (hereinafter also referred to as manner mode), the acceleration by vibration at the time of incoming call or alarm occurrence Is detected. Further, when the user of the mobile terminal moves while holding the mobile terminal (walking, jogging, stationary, etc.), the acceleration of vibration generated by the movement can also be detected. The acceleration data measured by the acceleration sensor 12 is output to the noise occurrence state determination means 13.

The noise generation state determination unit 13 is a unit that determines whether or not the calling operation of the mobile terminal is in a state of generating noise. For example, in the case where the manner mode is set, the acceleration data based on the vibration of the call operation measured by the acceleration sensor 12 is input to the noise generation state determination unit 13. The noise generation state determination means 13 analyzes the frequency characteristics of the data based on the input acceleration time series data, and determines the hardness of the portable terminal from the analysis result. Further, it is possible to determine a specific article name of the mobile terminal placed from the analysis result and the hardness. Then, based on the determination result, when the calling operation is performed by the vibration of the mobile terminal, it is determined whether or not the person around is disturbed by the sound generated by the vibration, that is, whether or not the noise is generated. The result of discrimination of the hardness, the article name, and the judgment of whether or not noise is generated are input to the call operation control means 14.

The hardness or the article name of the portable terminal is determined by using frequency characteristic pattern matching. The mobile terminal is placed on various items of different hardness, and the ringing operation is performed by vibration. The frequency characteristics based on the time series data of the acceleration detected in each case is obtained, and the characteristics are analyzed to determine the frequency. Data related to characteristics, hardness, and article name is stored in advance in storage means such as a memory. Then, the frequency characteristics analyzed at the start of the calling operation due to the vibration of the mobile terminal and the frequency characteristics stored in the storage means are pattern-matched, and the mobile terminal is placed by judging whether the pattern matches or similar Hardness and article name can be discriminated. When it is determined that the object on which the mobile terminal is placed is hard, the mobile terminal is determined to be in a noise generation state that generates noise (noise of a predetermined level or more) that is annoying to surrounding people due to a call operation caused by vibration. The

The call operation control means 14 starts the call operation of the mobile terminal based on the call request signal input from the call request unit 11, and starts determination processing by the noise generation state determination means 13 at the start of the call operation. It is a control means for making it. The calling operation of the portable terminal is started by controlling the vibration source control unit 15A, the sound source control unit 16A, and the light source control unit 17A. In response to a request from the call request unit 11, the call operation control unit 14 sends the vibration source control unit 15A, the sound source control unit 16A, or the light source control unit 17A corresponding to the call operation mode of the mobile terminal set at the time of the request. A control signal for starting the calling operation is output. The call operation control unit 14 determines the call operation corresponding to the determination by the noise generation state determination unit 13 and the determination result, and the call operation mode set at the time of the request from the call request unit 11 is determined. In order to switch to the call operation mode, a control signal for starting the call operation is output to the vibration source control means 15A, the sound source control means 16A, or the light source control means 17A. However, if the call operation mode determined from the discrimination and determination result is the same as the call operation mode set at the time of request, it is not necessary to set the same call operation mode again, and the call operation mode set at the time of request It is only necessary to maintain the operation mode setting.

The vibration source control means 15A controls the vibration source 15B as the calling means in accordance with the control signal sent from the calling action control means 14, and causes the mobile terminal to vibrate by the action of the vibration source 15B to execute the calling action. The sound source control means 16A controls the sound source 16B as the calling means in accordance with the control signal sent from the call operation control means 14, and causes the sound source 16B to output a sound from the portable terminal to execute the call operation. The light source control unit 17A controls the light source 17B as the calling unit in accordance with the control signal sent from the calling operation control unit 14, and causes the calling operation to be performed by emitting light from the portable terminal by the operation of the light source 17B.

As the vibration source 15B, an actuator that generates vibration in the mobile terminal, for example, a vibration motor, a piezoelectric element, a linear vibration actuator, or the like can be used. As the sound source 16B, an actuator for generating sound from the mobile terminal, for example, a speaker, a piezoelectric buzzer, a bell, or the like can be used. As the light source 17B, an actuator for generating light from the mobile terminal, for example, a light bulb, a light emitting diode, a liquid crystal screen, or the like can be used. Note that the vibration source 15B, the sound source 16B, the light source 17B, and the like for executing the calling operation are also referred to as a calling device. In addition, a sound source, a light source, and the like that are calling means other than the vibration source are also referred to as a non-vibration calling unit.

Here, as means for judging the hardness of the mobile terminal placed from the time series data of acceleration obtained by the acceleration sensor 12, the following means can be cited.
For example, by performing fast Fourier transform (FFT) on acceleration time-series data for a certain period of time, a certain signal waveform (acceleration time-series data) contains what frequency component and what percentage in a certain period of time. Is analyzed. The pattern of the power spectrum obtained by this analysis, that is, the frequency component included in the time-series information together with its intensity varies depending on the hardness of the portable terminal. Therefore, by using the characteristics of this power spectrum, as described above, the power spectrum acquired and stored in advance by placing the mobile terminal on different hardnesses and the newly acquired current mobile terminal are stored. The hardness is determined by pattern matching with the power spectrum of the object.

Further, for example, when the variance value (acceleration fluctuation amount) of the time-series data of acceleration for a certain period of time is larger than a certain threshold value, it may be determined that the portable terminal is hard. . In the case of this determination method, the fact that the dispersion value of the time-series data of acceleration due to vibration increases as the portable terminal is harder is used. The magnitude of the acceleration dispersion value at which the sound generated by vibration is felt as noise is determined in advance, the amount of change is set as a threshold value, and the variance value of the measured time series data is the threshold value. If it exceeds, it is determined that the mobile terminal is placed on a hard object that generates noise.

Next, based on FIG. 2, the operation | movement at the time of the incoming call of the control part which concerns on 1st Embodiment mentioned above is demonstrated.
When there is an incoming call or alarm to the mobile terminal, the call request unit 11 requests the call operation control means 14 to start the call operation of the mobile terminal (step S101). Upon receiving the call request, the call operation control means 14 starts the call operation in a mode (manner mode, normal mode, etc.) preset as the call operation for incoming calls and alarms (step S102). Here, a case where the manner mode, which is a call by vibration, is set will be described. The call operation control means 14 controls the vibration source control means 15A to operate the vibration source 15B to start a call operation by vibration.

Subsequently, it is determined whether or not the vibration being executed in this calling operation is a noise to the surroundings (step S103). With the start of the calling operation due to the vibration, acceleration data related to the vibration is measured by the acceleration sensor 12. The call operation control unit 14 controls the noise generation state determination unit 13 to execute the analysis of the frequency characteristic based on the time series data of the acceleration obtained by the acceleration sensor 12, and the frequency characteristic pattern obtained by this analysis is obtained. Then, the hardness of the portable terminal is determined by pattern matching with a plurality of frequency characteristic patterns measured in advance by analysis.

The frequency characteristics to be matched are those in which the mobile terminal is placed on a plurality of types having different hardnesses and the ringing operation by vibration is performed and measured. It is memorize | stored in the memory | storage means (memory) mounted in the portable terminal with the hardness of the cake. The noise generation state determination means 13 determines whether or not the hardness determined by pattern matching is a value greater than the hardness that causes noise to the surroundings (measured in advance), and the call operation due to this vibration is a noise. Is determined to be in a state of generating

If the determination result of “whether or not noise is generated” in step S103 is a determination result that there is no noise generation state, the mode set here as the call operation for incoming calls and alarms (here Then, the calling operation by vibration is continued while maintaining the manner mode (step S105). Then, when the user receives the call or when a preset call time elapses, the call operation by vibration is terminated (step S106).

On the other hand, when it is determined that the determination result in step S103 is in the noise generation state, the call operation control means 14 controls the vibration source control means 15A to stop the call operation due to vibration, and the sound source control means 16A. And / or the light source control means 17A is controlled to switch to the calling operation by sound and / or light (step S104). Then, the switched call operation is executed (step S105), and when the user receives it or when a preset call time elapses, the call operation by sound and / or light is terminated (step S106). Note that it is desirable that the ringing sound and / or light switching when it is determined that the noise is generated can be set by the selection of the user of the portable terminal.

If it is determined that the determination result in step S103 is not in a noise generation state, the manner mode is maintained in step S105, and the calling operation is performed with a high vibration level (strong vibration). You may make it do. At this time, it is desirable to determine again whether or not the vibration after increasing the level is in a noise generation state. Such an operation (intensifying vibration and re-determining the noise generation state) may be repeated a predetermined number of times or for a predetermined time.

According to the first embodiment having such a configuration, in a mobile terminal set in the manner mode, a ringing operation by vibration is executed at the time of an incoming call or an alarm, and acceleration by vibration is performed by an acceleration sensor mounted on the mobile terminal. To determine the hardness of what the mobile terminal is placed by analyzing the frequency characteristics of the measured time series data of acceleration, and from the results, whether the vibration of the mobile terminal generates noise If it is determined that it is in a state that generates noise, it is switched to a ringing operation that does not depend on vibration, so no matter where or where the mobile terminal is placed, Generation of noise due to the calling operation can be prevented. In addition, when it is determined that the noise is not generated, it is possible to make the user surely recognize the incoming call by making the determination again after the vibration is strengthened, and the change to the noise generation state. Can be determined immediately, and the generation of noise can be reliably prevented.

Furthermore, in order to prevent the generation of noise due to vibration, the following can be performed.
The initial level of vibration executed at the time of an incoming call or alarm of the mobile terminal is set to a level smaller than a normal vibration level (vibration level set by the user). The small vibration level here refers to a vibration level that does not hinder the measurement of acceleration by the acceleration sensor. This small level of vibration only needs to be output for a period until the determination of “whether or not the call operation by vibration generates noise” is completed. Uses the small vibration that is output to determine the presence or absence of noise (hardness of the mobile device is placed), and if it is determined that noise is generated in the call operation due to vibration, the call operation due to vibration is stopped. To switch to ringing operation by sound and / or light. On the other hand, if it is determined that no noise is generated in the call operation by vibration, the vibration level is reset to the normal vibration level (the small vibration level is set to the large vibration level), and the determination is completed. The call operation may be executed later with a normal vibration level.

Also, for example, the initial level of vibration executed at the time of incoming call or alarm of the mobile terminal may be set sufficiently small, and the level may be gradually changed greatly. The vibration level is changed until it reaches a level at which it can be sufficiently measured without hindering the acceleration measurement by the acceleration sensor, that is, a level at which it can be determined whether or not a noise is generated. As soon as the determination of whether or not the noise is generated is completed, in response to the determination result, when it is determined that the ringing operation by vibration generates noise, the ringing operation by vibration is stopped and the sound and / or light is stopped. Switch to the call operation by. On the other hand, if it is determined that the call operation due to vibration does not generate noise, the vibration level is reset to the normal level (vibration level set by the user), and the call is performed at the normal level after the above determination is completed. What is necessary is just to perform operation | movement.

When it is determined whether or not the call operation by vibration generates noise, the call operation by vibration is first executed until the determination is completed at the time of incoming call. Therefore, even if the mobile terminal is placed on a hard object that generates noise, the level of vibration that is executed until the determination is completed can be reduced. Occurrence can be completely prevented. Such a configuration can also be applied to the second and third embodiments described below.

Here, one form of the power spectrum obtained by analyzing the acceleration data detected by the acceleration sensor by FFT will be described with reference to FIG.
A mobile phone is used as the mobile terminal. Further, the acceleration sensor mounted on the mobile phone as the acceleration sensor 12, the vibration motor mounted on the mobile phone as the vibration source 15B, the speaker mounted on the mobile phone as the sound source 16B, and the mobile phone as the light source 17B were mounted on the mobile phone. A light emitting diode is used. The mobile phone is mounted as a device for executing the functions of the call request unit 11, the call operation control means 14, the noise generation state determination means 13, the vibration source control means 15A, the sound source control means 16A, and the light source control means 17A. A central processing unit and a storage device are used. The acceleration sensor can measure acceleration at a measurement frequency of 200 Hz, and the vibration motor can vibrate the mobile phone by operating at 90 to 100 revolutions per second.

When the mobile phone is set to the manner mode (calling by vibration), the contents of the control processing for appropriately switching the call operation according to the situation where the mobile phone is placed are as follows.
First, a mobile phone is actually placed on a plurality of types having different hardnesses, a vibration motor is operated to execute a calling operation by vibration, and acceleration due to the vibration is measured by an acceleration sensor. When the time series data (256 points) of acceleration for about 1.3 seconds is extracted from the acceleration data obtained by the measurement and analyzed by fast Fourier transform (FFT), the power spectrum as shown in FIG. Is obtained. In FIG. 3, the spectrum indicated by the □ point 18B is a power spectrum when the mobile phone is placed on the office desk and measured, and when the point 18A is placed on the glass table and measured, the △ point. When 19A is placed on a book and measured, the dot 19B represents the power spectrum when placed on a futon and measured.

As shown in FIG. 3, the peak value of the power spectrum (see FIG. 3) is used when a book or a futon has a relatively low hardness and no noise is generated even when a mobile phone is placed on the phone and a ringing operation is performed by vibration. 3) is relatively smaller than the value when placed on a hard object (peak value shown in circle 18 in FIG. 3), and the frequency of the peak value oscillates. It is close to the motor rotation speed of 90 to 100 Hz. On the other hand, the peak value of the power spectrum (FIG. 3) is relatively high when an office desk, a glass table or the like is relatively hard and a noise is generated when a cellular phone is placed on the office and a ringing operation is performed by vibration. The peak value shown in the inner circle 18) is relatively larger than the peak value (peak value shown in the circle 19 in FIG. 3) when placed on a non-hard object, and the frequency of the peak value is It is shifted in a direction smaller than 90 to 100 Hz which is the rotational speed of the vibration motor. Specifically, the frequency that is a peak value in the case of an office desk is about 80 Hz, and the frequency that is a peak value in the case of a glass table is about 90 Hz. From these characteristics, by analyzing the frequency characteristics based on the time series data of acceleration obtained by the acceleration sensor, it is possible to determine the hardness of the mobile phone placed and the placed one, and the call operation by vibration can be performed. It can be determined whether or not noise is generated.

When the mobile phone is set to the manner mode, a call request is issued from the call request unit 11 when there is an incoming call to the mobile phone. Upon receiving the request, the call operation control unit 14 controls the vibration source control unit 15A to execute a call operation by vibration for about 1.3 seconds, and acquires acceleration time-series data by the acceleration sensor 12. As soon as the time series data of the acceleration of about 1.3 seconds is acquired, the noise generation state determination unit 13 immediately performs analysis by fast Fourier transform to calculate a power spectrum, and executes pattern matching of the power spectrum. From the execution result, it is determined whether the mobile phone is placed and how hard it is, and whether or not the calling operation by vibration of the mobile phone is in a state of generating noise is determined. The call operation control means 14 controls the vibration source control means 15A to immediately stop the call operation due to vibration when it is determined that it is in a state of generating noise according to the result of the determination, and the sound source control The means 16A or / and the light source control means 17A are controlled to execute a calling operation (calling operation by sound or / and light) that does not depend on vibration. On the other hand, if it is determined that no noise is generated, the vibration source control means 15A is controlled to continue the call operation by vibration. These calling operations are stopped after a predetermined time set in advance.

Next, an embodiment of a program for realizing the functions of the control means 13, 14, 15A to 17A in the mobile terminal call operation control system will be described with reference to FIG.
The call operation control program 40 is read and executed by a call operation control device (information processing device) 41 which is an arithmetic processing device (computer). The call operation control device 41 is connected to the call request unit 11, the acceleration sensor 12, the vibration source 15B, the sound source 16B, and the light source 17B, and each is based on a control signal output from the call operation control device 41. Drive controlled.

The call operation control program 40 is a program for causing the call operation control device 41 to function as noise generation state determination means 41A, call operation control means 41B, vibration source control means 41C, sound source control means 41D, and light source control means 41E. It is.

[Second Embodiment]
The second embodiment of the present invention realizes a configuration for detecting whether or not noise is actually generated, and shows a second embodiment of a call operation control system for a portable terminal according to the present invention. 5 will be described. In this embodiment, the acceleration sensor 12 in the first embodiment is replaced with a microphone 8. In addition, about the part which attached | subjected the code | symbol same as 1st Embodiment, the same or equivalent part is shown and the description is the same.
The mobile terminal call operation control system 2 shown in FIG. 5 is centered on the call operation control means 14, and is electrically connected to the call request unit 11, noise generation state determination means 23, vibration source control means 15A, sound source control. 16A, a light source control means 17A, a microphone 22 connected to the noise generation state determination means 23, a vibration source control means 15A, a sound source control means 16A, and a vibration source 15B connected to the light source control means 17A, respectively. A sound source 16B and a light source 17B are included.

The microphone 22 is mounted on the mobile terminal and measures sound generated around the mobile terminal. Specifically, for example, when the calling operation of the mobile terminal is set to a ringing by vibration instead of a ringing by sound (hereinafter also referred to as a manner mode), it is generated by vibration at the time of an incoming call or when an alarm occurs. Detect sound to be played. The sound data measured by the microphone 22 is output to the noise generation state determination means 23.

The noise generation state determination means 23 is a means for determining whether or not the calling operation of the mobile terminal is in a state where noise is generated. For example, in the case where the portable terminal is set to the manner mode, sound data based on the vibration of the call operation measured by the microphone 22 is input to the noise generation state determination unit 23. The noise generation state determination means 23 analyzes the frequency characteristics of the data based on the time-series data of the input sound, and determines the hardness of the portable terminal from the analysis result. Further, it is possible to determine a specific article name of the mobile terminal placed from the analysis result and the hardness. Then, based on the determination result, when a calling operation is performed by vibration of the mobile terminal, it is determined whether or not a person around is disturbed by the sound generated by the vibration, that is, whether the sound becomes noise. The determination result of the hardness and the article name and the determination result of whether or not it corresponds to noise are input to the call operation control means 14.

The hardness or the article name of the portable terminal is determined by using frequency characteristic pattern matching. Place the mobile terminal on various items of different hardness and perform a ringing operation by vibration. Obtain frequency characteristics based on the time-series data of the sound detected in each case, analyze the characteristics and analyze the frequency. Data related to characteristics, hardness, and article name is stored in advance in storage means such as a memory. The frequency characteristics analyzed at the start of the calling operation due to the vibration of the mobile terminal and the frequency characteristics stored in the storage means are subjected to pattern matching to determine whether the pattern matches or similar, and the mobile terminal is placed Hardness and article name can be discriminated. When it is determined that the object on which the portable terminal is placed is hard, it is determined that the portable terminal is in a noise generation state in which noise is generated by a call operation caused by vibration.

Here, as means for determining the hardness of the mobile terminal placed from the sound time-series data obtained by the microphone 22, there are the following means.
For example, by performing fast Fourier transform (FFT) on sound time-series data for a certain period of time, a certain signal waveform (sound time-series data) contains what frequency component and what percentage at a certain time. Is analyzed. The pattern of the power spectrum obtained by this analysis, that is, the frequency component included in the time-series information together with its intensity varies depending on the hardness of the portable terminal. Therefore, by using the characteristics of this power spectrum, as described above, the power spectrum acquired and stored in advance by placing the mobile terminal on different hardnesses and the newly acquired current mobile terminal are stored. The hardness is determined by pattern matching with the power spectrum of the object.

Further, for example, when the amplitude (volume) of the time-series data of the sound for a certain period of time is larger than a certain threshold value, it may be determined that the portable terminal is hard. In the case of this determination method, it is used that the amplitude of the time-series data of the sound due to vibration becomes larger as the portable terminal is harder. When the amplitude of the sound generated by vibration is determined in advance and the volume is set as a threshold, and the measured time-series data amplitude exceeds the threshold Determines that the mobile terminal is placed on a hard object that emits noise.

Next, based on FIG. 6, the operation of the control unit according to the second embodiment at the time of an incoming call will be described. Here, Steps S201 and S202 and Steps S204 to S206 have the same contents as Steps S101 and S102 and Steps S104 to S106 in the first embodiment described above.

In FIG. 6, in step S203, it is determined whether or not the vibration being executed in the calling operation in step S202 is noise relative to the surroundings. The sound data relating to the vibration is measured by the microphone 22 together with the start of the calling operation due to the vibration at the time of an incoming call or an alarm. The call operation control unit 14 controls the noise generation state determination unit 23 to perform the analysis of the frequency characteristic based on the time series data of the sound obtained by the microphone 22, and the frequency characteristic pattern obtained by this analysis is expressed as follows. Pattern matching is performed with a plurality of frequency characteristic patterns measured in advance by analysis to determine the hardness of the portable terminal.

The frequency characteristics for matching are those in which the mobile terminal is placed on a plurality of types having different hardnesses and measured by performing a ringing operation by vibration, the mobile terminal being placed, and It is memorize | stored in the memory | storage means (memory) mounted in the portable terminal with the hardness of the thing put. The noise generation state determination means 23 determines whether or not the hardness determined by pattern matching is a value greater than the hardness that causes noise to the surroundings (measured in advance), and the call operation by this vibration is a noise. Is determined to be in a state of generating

According to the second embodiment having such a configuration, in the mobile terminal set to the manner mode, a ringing operation by vibration is executed at the time of an incoming call or an alarm, and sound due to vibration is generated by a microphone mounted on the mobile terminal. Measure and analyze the frequency characteristics of the time-series data of the measured sound to determine the hardness of what the mobile terminal is placed on, and determine whether the vibration of the mobile terminal generates noise from those results Thus, when it is determined that the noise is generated, the call operation is switched to a vibration operation that does not depend on vibration, and thus the same effect as in the above-described embodiment of FIG. 1 can be obtained.

For example, in the case where the manner mode is set, the noise generation state determination unit 33 is input with acceleration data and sound data due to the vibration of the call operation measured by the acceleration sensor 12 and the microphone 22. The noise generation state determination means 33 analyzes the frequency characteristics of the data based on the input acceleration and sound time-series data, and determines the hardness of the portable terminal from the analysis result.

More specifically, first, similarly to the noise generation state determination unit 13 shown in the first embodiment, the hardness of the portable terminal is determined based on the acceleration data measured by the acceleration sensor 12, and the vibration is determined. It is determined whether or not noise is generated by the paging operation. As a result, when it is determined that the noise is generated, the determination result becomes the determination result of the noise generation state determination unit 33. In this case, the determination based on the sound data is not performed.

On the other hand, when it is determined that the determination result based on the data of the acceleration sensor 12 is not in a state where noise is generated, the noise generation state determination unit 23 shown in the second embodiment is continued. Similarly, the determination based on the data of the microphone 22 is performed. Sound data is measured by the microphone 22, and the hardness of the portable terminal is determined based on this data, and it is determined whether or not noise is generated by the call operation due to vibration. As a result, when it is determined that the noise is generated, the determination result is the determination result of the noise generation state determination unit 33. On the other hand, when it is determined that the noise is not generated, the determination result is the determination result of the noise generation state determination unit 33.

In step S303A, it is determined whether or not the vibration being executed in this calling operation is noise to the surroundings. Along with the start of the calling operation due to the vibration, the acceleration sensor 12 measures acceleration data related to the vibration. The call operation control unit 14 controls the noise generation state determination unit 33 to perform frequency characteristic analysis based on the time series data of acceleration obtained by the acceleration sensor 12, and the frequency characteristic pattern obtained by this analysis is obtained. Then, the hardness of the portable terminal is determined by pattern matching with a plurality of frequency characteristic patterns measured in advance by analysis. The noise generation state determination means 33 determines whether or not the hardness determined by pattern matching is a value greater than the hardness that causes noise to the surroundings (measured in advance), and the call operation by this vibration is a noise. Is determined to be in a state of generating

If it is determined as a result of the determination in step S303A that noise is generated, the process proceeds to step S304, the call operation is switched, and then the process proceeds to step S305. On the other hand, if the determination result in step S303A is that there is no noise generation, the process proceeds to step S303B, and a determination based on the sound data measured by the microphone 22 is performed.

If it is determined as a result of the determination in step S303B that noise is generated, the process proceeds to step S304, the call operation is switched, and then the process proceeds to step S305. On the other hand, when it is determined that the determination result in step S303B is not in a state of generating noise, the process proceeds to step S305, and the call operation by vibration is continued while maintaining the manner mode.

Thus, first, determination based on the data of the acceleration sensor is performed, and when it is determined that the noise is not generated, determination based on the data of the microphone 22 is further performed to determine a final determination result. Therefore, it is possible to reliably avoid erroneous determination of noise generation, and to achieve high accuracy of the determination result. Note that the order of both determinations may be based on the microphone data. In addition, the determination is always performed based on both data. When the determination results are different, both determinations are performed. The final result may be determined after repeating a plurality of times.
