The exemplary embodiments of a call control method and module of a smartphone having a dual speaker according to the present invention can be variously applied, and the most preferred embodiments will be described below with reference to the accompanying drawings.

FIG. 1 is a flowchart illustrating a call control method of a smart phone having a dual speaker according to the present invention. In the following description, a call control method is described with a smart phone as a main body, but the present invention is not limited thereto. The present invention can be implemented by a module configured in a smart phone or an application (app, App) downloadable for performing the call control method of the present invention.

Referring to FIG. 1, the smart phone confirms whether the automatic mode is set when the ring signal is received, and confirms the user setting information when the automatic mode is set (step S100). Here, the ring signal refers to a signal transmitted from the repeater to the smartphone to indicate that the call is requested, and when the smart phone receives the ring signal, the user is informed that the call is coming.

In addition, if the automatic mode is not set, the automatic mode can be set by the user, which will be described in more detail below.

The smart phone receives and analyzes the detection signal from the gripping sensor based on the set user setting information, and confirms the grip state of the smartphone by the user (step S200). Here, the gripping sensor may include a pressure sensor, a gravity sensor, and a touch screen sensor, and a process of checking the gripping state by each sensor will be described in more detail below. The configurations of the pressure sensor and the gravity sensor are not limited to the specific ones because various modifications can be made according to the needs of those skilled in the art.

The smartphone starts a call by selecting one of a front call mode, a rear call mode, and a two-way call mode according to the state of the user's finger (step S300).

On the other hand, when the user changes the hand to hold the smartphone during a call, for example, when the user hands the handset while changing a hand in the full-call mode while grasping with the left hand as shown in FIG. 7, The smartphone can be changed from the full call mode to the rear call mode.

In order to prevent this, the smartphone of the present invention can discard all the detected signals after the first call mode is selected, and prevent the call mode from being changed in a state in which the user does not intend .

Of course, the call mode may need to be changed according to a user's request. To this end, in the present invention, when the control mode change key for the call mode is input during the call, the call mode is changed from one call mode to another (Step S400). Here, the control key for changing the communication mode may include a volume control key (not marked) configured on the side of the smartphone.

FIG. 2 is a flowchart illustrating an automatic mode setting process performed before the method of FIG.

Referring to FIG. 2, when a user executes an application installed as a basic function or downloaded from an external device (step S11) to control the call of the smartphone, the application determines whether the automatic mode for call control is set (Step S12). It should be understood that the process performed by the application is performed by the processor executing the application.

If the automatic mode is not set (step S12), it can be confirmed whether or not the automatic mode is set by the user (step S13). At this time, if the user does not set the automatic mode (step S13), the smartphone can be set to the manual mode in which the communication mode is changed by the user's operation (step S19).

If it is confirmed that the automatic mode is set (step S13), the application can confirm the type of the phage detection sensor configured in the smart phone (step S14) and receive the user setting information corresponding to the phage detection sensor (step S15 ).

Here, the reason for confirming the phage detection sensor is that the pressure sensor or the gravity sensor described in the present invention may not be configured in the case of a smartphone that has downloaded the application.

Therefore, the present invention can perform a call control method of a smart phone by using a touch screen sensor basically configured in most smart phones, so that it can be easily applied to a smart phone already in use.

In addition, in the case of a smart phone including a pressure sensor or a gravity sensor in addition to the touch screen sensor, it is of course possible to confirm the grip state by the improved accuracy.

In one embodiment, when the phage detection sensor includes a first pressure sensor and a second pressure sensor respectively configured on both sides of the smartphone (step S14), the application receives a hand and a call type (Step S15). In accordance with the selection result, the sensing signal to be sensed by the pressure sensor at the time of a subsequent call may be matched with the communication mode and stored as user setting information (step S16). Here, as shown in FIG. 7 and FIG. 8, a call type may include a method of making a call with a smartphone or a method of making a call with a smartphone in the ear.

In another embodiment, if the phage detection sensor includes a gravity sensor (step S14), the application can select a hand and a call type that the user mainly uses in a call (step S15) And stores the detected information as the user setting information.

After storing the user setting information as described above (step S16), the application can set the automatic mode (step S17).

When the setting of the automatic mode is completed, it is possible to switch to the ring signal reception waiting state for the call (step S18).

As shown in FIG. 2, matching and storing the user setting information for each sensor allows the smartphone to be held by different users in different ways. Therefore, if the user sets whether to grasp the smartphone with the left hand or grasp with the right hand, the user can grasp the grasp state more accurately when determining the communication mode after receiving the ring signal.

Also, when the user setting information is stored, the sensing signal received from each of the sensors in the virtual call state can be stored and the communication mode can be determined based on the stored sensing signal. This is because, even if the hand and currency forms used in the call are the same, the users may differ slightly. For example, even if a smartphone is grasped as shown in FIG. 7, the slope of the smartphone or the pressure of the finger holding the smartphone are different according to the user, and the detection signal held by the user in a virtual call state is stored And comparing the detected signal with the detection signal when determining the communication mode after receiving the ring signal, the grasping state can be confirmed by the improved accuracy.

Meanwhile, the smartphone can be roughly divided into two types according to the position of the speaker and the microphone, which are shown in FIG. 3 and FIG.

FIG. 3 is a block diagram illustrating an embodiment of a smartphone to which the method of FIG. 1 is applied.

3, the smartphone 100 may include two different loudspeakers in one microphone. The front loudspeaker 111 is connected to the display (touch) of the smartphone 100 as shown in FIG. 3 (a) The back speaker 112 may be configured on the upper part of the rear surface of the smartphone 100 as shown in FIG. May be configured on the lower surface of the smartphone 100 as shown in FIG. 3 (c).

Such a smartphone 100 can mainly perform a call as shown in FIG.

FIG. 4 is a block diagram illustrating another embodiment of a smartphone to which the method of FIG. 1 is applied.

4, the smartphone 100 may include two speakers and two microphones, and the front speaker 111 and the front microphone 121 may be connected to the smartphone 100 as shown in FIG. 4 (a) The back speaker 112 and the rear microphone 122 may be respectively configured on the upper and lower portions of the rear surface of the smartphone 100 as shown in FIG. Respectively.

Such a smartphone 100 can mainly perform a call as shown in FIG.

As described above, the form of call may be changed according to the location and configuration of the microphone of the smartphone 100. In addition, in the case of the smartphone 100 configured as shown in FIG. 4, the user can talk as shown in FIG. Therefore, in step S15 of FIG. 2, it is necessary to set a call type in advance according to the configuration of the smartphone 100 and the request of the user.

5 is a flowchart specifically illustrating step 'S200' of FIG.

Referring to FIG. 5, an application installed in a smart phone can confirm whether or not an automatic mode is set when a ring signal is received (step S201).

When the automatic mode is set, the application can check which sensor is used to determine the grip state (step S202). Preferably, it is possible to use the sensors set in step < RTI ID = 0.0 > S16 '

In one embodiment, in the case of checking the state of gripping using a pressure sensor (step S202), the application can receive and check the sensing signals of the first pressure sensor and the second input sensor, respectively, (Step S203). For example, as shown in FIG. 6, 'P1' to 'P6' having relatively high pressures can be confirmed, and the number of points sensed by the first pressure sensor and the number of points sensed by the second input sensor , It is possible to judge the side in which a relatively large number of sensed sides are gripped with the fingers.

Then, the application can check the stored state of the smartphone (step S208) based on the comparison result and the user setting information (step S207). For example, in a state where the user sets the smartphone to be in a left-handed state, 'P1' and 'P2' are set by the first pressure sensor (configured on the left side of the smartphone in FIG. 6) And P3 'to P6' are detected by the second pressure sensor (configured on the right side of the smartphone in FIG. 6), the application determines that the user grasps the front face of the smart phone with the left hand . Here, 'P1' to 'P6' indicate that the pressure is relatively higher than the adjacent region even though the pressure values at the respective points are different from each other.

In another embodiment, when the grip state is confirmed using the gravity sensor (step S202), the application can check the three-axis tilt of the smartphone by analyzing the sensing signal of the gravity sensor (step S204). As a result, when the smartphone is moved as shown in FIG. 7 or FIG. 8, it is possible to confirm how the current user grasps the smartphone by checking the angle (slope) rotating around the three axes in space.

Then, the application can match the gravity sensor to call stored user setting information (step S206), and check the smartphone's grip state based on the comparison result and the user setting information (step S207) (step S208). For example, if the user has confirmed that the smartphone is set to make a call with the left hand and the user is inclined as shown in FIG. 8, it can be determined that the current user uses the back side of the smartphone to make a call. As shown in FIG. 8, when the smartphone is set in the right-handed state in the user setting information in a tilted state, it can be determined that the current user uses the front face of the smartphone to make a call.

In another embodiment, in the case of checking the grip state using the touch screen sensor (step S202), the application receives the touch signal of the touch screen sensor and analyzes the received touch signal to check the contact area size (Step S205).

Then, the application can call the stored user setting information (for example, a setting area set as a border for distinguishing the touch by the finger and the face contact) matched with the touch screen sensor (step S206) After comparing the setting area included in the setting information with the contact area (step S207), if the touch area is larger than the setting area, it can be determined that the touch screen is grasped to face the user's face (step S208).

FIG. 9 is a flowchart specifically illustrating step 'S400' in FIG.

Referring to FIG. 9, when the call is started in step S300 of FIG. 1, the current call mode can be confirmed (step S401), and the call state can be maintained (step S402). Of course, as shown in step S400 of FIG. 1, steps S401 and S402 may be performed even if the talk mode is changed by the control key.

In the case where a touch by a finger is detected in a state where the communication state is maintained as described above (step S403), that is, when the contact area confirmed by step S205 of FIG. 5 is smaller than the setting area, The corresponding function can be performed according to the touch (step S404).

If it is determined that a contact with a larger area than the touch by the finger is detected (step S403), the application may determine that the contact is caused by the face of the user at the time of communication and discard the detection signal (step S405). In addition, when the application receives a sensing signal from at least one of the pressure sensor and the gravity sensor during a call, the application determines that the sensing signal is input in a state that the user does not intend during communication, can do.

If the call mode is terminated (step S406), the information on the changed call (for example, the call according to the user setting information) In the case where the communication mode is changed by inputting the control key during the execution of the mode) and can switch to the standby mode for receiving the ring signal.
