[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile phone provided with a speaker detachably.
[0002]
[Prior art]
Conventionally, in a mobile phone, a display screen, a speaker, and a microphone are all fixed to a mobile phone main body (hereinafter referred to as a main body). In such a mobile phone, the speaker and microphone of the main unit are brought close to the ear and mouth when making a call, and when the display screen is viewed when not in a call, the main unit is moved from the face to a distance where the display screen can be seen. It comes to separate.
This is because mobile phones are mainly used for voice calls, and in such calls, it is not necessary to perform output from the speaker and input from the microphone when viewing the display screen.
[0003]
[Problems to be solved by the invention]
However, when a plurality of types of data such as text data, image data, and audio data are communicated in a mobile phone, the following problems occur.
For example, when viewing multimedia mail with image data and audio data added, the mobile phone user needs to listen to the audio while looking at the display screen, but the speaker of the main unit is brought close to the ear. The screen cannot be viewed, and if the speaker is moved away from the ear to view the screen, the sound cannot be heard. This is because, in a conventional mobile phone, the volume output from the speaker is adjusted so as to listen with the ear approaching the speaker.
This problem can be solved by operating a button or the like provided on the main body to increase the volume, but there is a problem that increasing the volume of the speaker compared to that during a normal call may cause annoyance to others. For this problem, some earphones etc. are connected to the main body to listen to the sound, but when using such earphones, the earphones must be connected one by one. Inconvenient.
[0004]
The same applies when making a call while looking at the screen. If you place the microphone of the main unit close to your mouth, you will not be able to see the screen. The problem arises. This is because the sensitivity of the microphone is adjusted so that the mouth approaches the microphone and speaks.
Even in this case, it is possible to increase the sensitivity by operating the buttons etc. provided on the main body, but when listening to voice or making a call while looking at the display screen, the display screen is similar to a conventional call. It is very inconvenient to switch the volume of the speaker and the sensitivity of the microphone when talking without talking.
In addition, when calling with the main body close to the face, there is also a problem that power is wasted if the display screen remains displayed even though the display screen is not viewed.
In this way, conventional mobile phones must be used in a manner that wastes power, and may be inconvenient in terms of operability, and will cause inconvenience to those around you when trying to eliminate the inconvenience, There was a problem that the use mode was limited.
[0005]
The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide a mobile phone with few restrictions on usage.
[0006]
[Means for Solving the Problems]
In order to solve the above-described problem, the invention according to claim 1 is a mobile phone including a speaker that can be attached to and detached from the main body, and determines whether or not the speaker is attached to the main body. And when the speaker is attached to the main body in the attachment / detachment state determination means, the attachment mode is set. When the speaker is determined to be isolated from the main body, the isolation mode is set. When setting a mode setting means to be set and when starting a voice call at the time of an incoming call or starting browsing of multimedia mail, the functions of the mobile phone are controlled based on the mode set by the mode setting means. And a function control means.

Further, as shown in FIG. 2, the speaker storage unit 14 is provided with a sensor 15 that detects whether or not the speaker 2 is attached to the main body 1. As will be described in detail later, the sensor 15 switches between a “mounting mode” in which the speaker 2 is mounted on the main body 1 and a “separation mode” in which the speaker 2 is separated from the main body 1 based on the detection result. Is used for this purpose.
[0011]
[2. Functional configuration of mobile phone]
FIG. 3 is a block diagram showing a functional configuration of the mobile phone in the present embodiment. In addition, description is abbreviate | omitted about the detail of the electrical structure which implement | achieves each function shown here.
As shown in FIG. 3, the mobile phone in the present embodiment controls the display screen 11, the microphone 12, and the sensor 15 described above, the control unit 20 that performs control described in detail later, and the display mode on the display screen 11. Display controller 21, sensitivity setting unit 22 for setting the sensitivity of microphone 12, mode setting unit 23 for setting the above-mentioned “wearing mode” or “separation mode”, and speaker 2 based on detection by sensor 15. An attachment / detachment state determination unit 25 that determines the attachment / detachment state is provided.
[0012]
In the present embodiment, the sensitivity of the microphone 12 and the display mode of the display screen 11 can be switched based on the above-described setting of “mounting mode” or “separation mode”.
The mounting state determination unit 25 illustrated in FIG. 3 determines the attachment / detachment state of the speaker 2 based on the detection of the sensor 15, and the control unit 20 determines the mode setting unit based on the determination in the mounting state determination unit 25. 23 switches the setting of “mounting mode” or “separation mode”.
[0013]
FIG. 4 is a flowchart showing the contents of the control processing in the control unit 20, and this processing is started when the detection state in the sensor 15 changes.
When the speaker 2 changes from the state in which the speaker 2 is attached to the main body 1 to the state in which the speaker 2 is separated from the main body 1, for example, the detection state of the sensor 15 changes from an energized state to a cut-off state. The control unit 20 starts the process shown in FIG.
The control unit 20 refers to the determination result performed by the mounting state determination unit 25 based on the detection state in the sensor 15, and determines whether or not the speaker 2 is mounted on the main body 1 (S101).
If it is determined that the speaker 2 is attached to the main body 1 (S101; Yes), the control unit 20 switches the mode setting in the mode setting means 23 to “attachment mode” (S102), and this process Exit.
On the other hand, if it is determined in step S101 that the speaker 2 is not attached to the main body 1 (S101; No), the control unit 20 switches the mode setting in the mode setting means 23 to “isolation mode” ( S103), this process is terminated.
[0014]
Next, FIG. 5 shows the control executed by the control unit 20 when it is necessary to switch the sensitivity of the microphone 12 and the display mode of the display screen 11 based on the setting of the “mounting mode” or “separation mode”. It is the flowchart which showed the processing content.
For example, it may be executed when a voice call is started at the time of an incoming call, or may be executed when browsing of multimedia mail is started.
When the processing shown in FIG. 5 is started, the control unit 20 first refers to the setting state in the mode setting unit 23 and determines whether it is “mounting mode” or “separation mode” (S201).
If it is determined in step S201 that the “mounting mode” is set, the control unit 20 causes the sensitivity setting unit 22 to set the sensitivity of the microphone 12 to be low, and causes the display control unit 21 to turn off the display mode of the display screen 11. (S202).
On the other hand, if it is determined in step S201 that it is in the “isolation mode”, the sensitivity setting unit 22 sets the sensitivity of the microphone 12 to be high, and causes the display control unit 21 to control the display mode of the display screen 11 to the ON state. (S203).
[0015]
More specifically, the sensitivity in the wearing mode, that is, the sensitivity of the microphone 12 set in step S202 in FIG. 5 is set to an optimum value that does not cause distortion even if the microphone 12 is very close to the microphone. .
On the other hand, the sensitivity in the separation mode, that is, the sensitivity of the microphone 12 set in step S203 in FIG. 5 is a value that can be sufficiently input even when a voice is produced at a distance of viewing the display screen 11, for example, 25 cm away from the microphone 12. Set.
The set value for each mode may be stored in the mode setting unit 23 as a fixed value in advance by measurement, or may be input or changed by an operation on the operation unit 13. May be.
[0016]
As described above, the sensitivity of the microphone 12 in the remote mode is set to be higher than the sensitivity of the microphone 12 in the mounting mode. Even if you do it, you don't have to make a loud voice and you don't have to use it to bother others.
Since the switching of the mode is performed based on detection by the sensor 15, it is not necessary to perform the switching operation using the operation unit 13, and the operability of the mobile phone is improved.
[0017]
Further, it is determined whether or not to display on the display screen 11 depending on whether the remote mode or the wearing mode, and no display is made during a call in the wearing mode, and during a call in the remote mode. Since the display is performed, when there is no need to view the display screen 11, the display is not performed on the display screen 11, and the power consumption can be suppressed.
[0018]
