Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the following description, a mobile phone is described as an example of the electronic device according to the present invention. However, the present invention may be applied to any electronic device equipped with a speaker or a microphone in addition to a mobile phone.

1A to 1C illustrate a method in which a user controls an audio output of a mobile phone using a gesture according to an embodiment of the present invention.

The mobile phone shown in FIG. 1A is a mobile phone called a full touch screen phone. The full touch screen phone does not have a button for inputting a phone number. Instead, the display 12 occupies a relatively large area of the appearance of the mobile phone 10, and the display 12 is equipped with a touch screen, and when the power is turned on. A phone number entry button is displayed on the touch screen of the mobile phone. The description herein may be applied to other types of mobile phones.

A touch sensor 16 capable of detecting whether a touch is mounted may be mounted around the speaker 11 of the mobile phone 10 according to an exemplary embodiment of the present invention.

When receiving a call signal from the mobile phone 10 as shown in Figure 1a, the call reception signal is output. For example, a ring tone may be output through the speaker 11. When receiving a call signal, vibration or lamps may flash instead of ringing.

The caller information 13 may be displayed on the display 12. In addition, an icon 14 indicating the current audio output mode may be displayed. The icon 14 in FIG. 1A indicates that an audio signal is normally output through the speaker 11.

While receiving the call signal, when the user touches the touch sensor 16 disposed around the speaker 11 as shown in FIG. 1B, the call reception signal indicating that the call signal is being received is blocked as shown in FIG. 1C. can do. When the call reception signal is blocked, the ring tone set as the call reception signal no longer rings, the vibration signal is stopped, or the lamp no longer blinks.

Preferably, when the call reception signal is blocked, it may be indicated by the icon 14 that the call reception signal is blocked, as shown in FIG. The icon 14 shown in FIG. 1C indicates a state in which audio output through the speaker 11, that is, a ring tone is blocked. According to an exemplary embodiment, another type of icon may be displayed, or a message indicating that a call reception signal is blocked may be displayed.

Preferably, the touch sensor 16 is disposed as close to the speaker 11 as possible, and more preferably, it can be mounted at the same position as the speaker 11. In some embodiments, the touch sensor 16 may have the same color as the case of the mobile phone 10 inconspicuous to the user.

Through the above configuration, the user may have a feeling of blocking the sound by blocking the speaker 11 by hand rather than the touch sensor 16. Therefore, the user can control the audio output through a method more intuitive to the user.

2 to 4 illustrate an audio output control method of a mobile phone according to another embodiment of the present invention.

When the user wants to block the call reception signal while the call signal is being received, a gesture that blocks the speaker 11 may be used as shown in FIG. 1B, but the call reception signal may be blocked using another gesture.

For example, instead of the touch sensor 16 of FIGS. 1A to 1C, a proximity sensor 17 capable of sensing the proximity of an object may be mounted near the speaker 11 of the mobile phone 10 as shown in FIG. 2. When the user does not touch the hand with the speaker 11 and approaches the hand or the object within the sensing distance of the proximity sensor 17, the call reception signal of the mobile phone 10 may be blocked.

The proximity sensor 17 measures the change in capacitance, the change in electric field or the change in inductance as the user's finger or styler approaches the mobile phone 10, using the Hall effect, and the lead. ) Sensor, eddy current sensor, magnetoresistive sensor, shadow sensor, visible light sensor, infrared sensor, color sensor, ultrasonic sensor, acoustic sensor, radar, thermal sensor, sonar, conductivity detector, resistance detector, etc. Can be used.

Preferably, when the electronic device is a mobile terminal such as a mobile phone, PDA, notebook, etc., the proximity sensor 17 may be a PSD (Photo Sensitive Dectector) that is easy to mount on the mobile terminals. In addition, according to the exemplary embodiment, a method of calculating the distance from the image captured by the proximity sensor 17 using the image sensor for imaging to the user through image processing may be used.

In another embodiment, the user sweeps over the display 12 on which the touch screen panel of the mobile phone 10 is mounted, without using the touch sensor 16 of FIGS. 1A-1C as shown in FIG. 3. You can use gestures. When the user detects a gesture of sweeping the palm of the hand over the display 12, the audio output of the mobile phone 10 may be blocked.

The sweeping gesture of the user may be configured to determine that the sweeping gesture is input when a predetermined area, for example, 70% or more of the touch screen panel mounted on the display 12 is simultaneously touched by an object, that is, a palm.

In another embodiment according to the present invention, when a movement of an object moving from one end to the other end on the display 12 is detected, it may be configured to determine that the sweeping gesture is input.

In another embodiment according to the present invention, a gesture of blocking audio output of a user may be detected without using a touch screen, a touch sensor, or a proximity sensor. The volume of the ring tone through the speaker 11 may be measured by the microphone 15. Using this, the user's gesture can be detected through the change in the volume measured by the microphone 15.

While the call signal is received and the ring tone is output as shown in FIG. 4, the user may block the speaker 11 with a finger or other object. When the user blocks the speaker 11, the volume of the ring tone being output through the speaker 11 is greatly reduced. For example, when the volume measured by the speaker 11 decreases to 1/3 or less, it may be determined that the speaker 11 is blocked. Although it is determined that the speaker is blocked, the specific volume reduction value as a reference may vary depending on the performance of the speaker, the configuration, the size of the speaker 11, and the like.

The microphone 15 may be configured to measure the volume of a specific ring tone output through the speaker 11 after the call signal is received. When the volume of the specific ring tone is detected by the microphone 15 as a predetermined value is reduced, the controller of the cellular phone 11 may determine that the user has blocked the speaker 11 with a finger or the like and block the ring tone.

In the embodiment described with reference to FIGS. 1A to 4, any object touches or approaches the touch sensor 16 or the proximity sensor 17 that is not intended by the user but is mounted on the mobile phone 10, or the speaker 11 is used. Can be blocked. For example, such a phenomenon may occur when a call comes while the mobile phone 10 is in a pocket or a bag. If the call reception signal of the mobile phone 10 is blocked by the user, the user may not recognize whether the call signal is received.

To prevent this, when the call signal is received, the call reception signal may be blocked in response to the user's gesture only when the user additionally operates before or after the gesture described with reference to FIGS. 1A through 4. .

As shown in FIG. 5, a specific menu for blocking the audio output is displayed, for example, the "unsubscribe" menu 17, the user selects the menu by touching or using a physical button, and then performs the gesture of FIGS. 1A to 4. It can be configured to block the call reception signal.

In another embodiment, a specific physical button on the mobile phone 10, for example, a specific button is mounted on the side of the mobile phone 10, while pressing the button to perform the gesture as shown in Figs. It may also be configured to. Preferably, the button may be placed at the position where the thumb or index finger is placed when the user grabs the mobile phone 10. The user may hold the mobile phone 10 with one hand and apply the gesture with the other hand while pressing the button with a thumb or index finger.

In an embodiment according to the present invention, when the same gesture is applied while the call reception signal is blocked, the call reception signal may be blocked.

Alternatively, when the same gesture is applied again while the call reception signal is blocked, the call may be connected.

6A to 6B illustrate a method of blocking audio input during a phone call to a mobile phone using a gesture of a user according to an embodiment of the present invention.

As shown in FIG. 6A, the touch sensor 19 is mounted near the microphone 15 of the mobile phone 10 according to the exemplary embodiment of the present invention.

Preferably, the touch sensor 19 is arranged at the position as close as possible to the microphone 15. More preferably, it may be mounted at the same position as the speaker 11. In one embodiment, the touch sensor 19 may have the same color as the case of the mobile phone 10 inconspicuous to the user.

During the call, the display 12 of the mobile phone 10 may display information such as the talk time 18 up to now. In some embodiments, a menu that can be used during a phone call such as a memo and a phone number search may be displayed during the call.

When the user touches the touch sensor 19 next to the microphone 15 with a finger or any other object as shown in FIG. 6B, the user's voice input to the microphone 15 is blocked and no voice is transmitted to the other party of the call. That is, the mobile phone 10 enters the voice cut mode.

In the voice cut mode, the controller (not shown) of the mobile phone 10 may be configured to ignore all inputs input through the microphone 15. Optionally, the controller may be configured to disable the operation of the microphone 15 by, for example, cutting off power to the microphone 15.

In one embodiment, the voice cut mode may be configured to deliver a voice message informing the other party of the call that the voice cut state is in place of the user's voice.

Through the above configuration, the user may have a feeling of blocking the sound by blocking the microphone 15 by hand rather than the touch sensor 19. Therefore, the user can control the audio output through a method more intuitive to the user.

In other embodiments, the proximity sensor may be mounted instead of the touch sensor 19 near the microphone 15. In the case of using the proximity sensor, when the user moves the hand near the microphone 15, the proximity sensor detects the proximity of the object, and the controller of the mobile phone 10 ignores the voice input to the microphone 15 such as the user's voice. Alternatively, the operation of the microphone 15 is disabled so that voice is not transmitted to the other party of the call. The distance that the proximity sensor responds to in proximity of the object depends on the type of proximity sensor. As the proximity sensor in this embodiment, the same thing as the proximity sensor 17 in the embodiment of FIG. 2 described above can be used.

In one embodiment, when the user takes a gesture as shown in Figure 3 during a call, it can be configured to block the user's voice. That is, when the user sweeps the palm of the mobile phone 10 on the display 12 on which the touch screen panel is mounted, the controller of the mobile phone 10 detects the gesture through the touch screen and the microphone 15. Can be configured to block voice input.

As in the embodiment of FIG. 3, the sweeping gesture of the user may be configured to determine that the sweeping gesture is input when a predetermined area, for example, 70% or more of the touch screen panel is simultaneously touched by an object, that is, a palm.

6A to 6B, any object may touch or approach the touch sensor 19 or the proximity sensor that is not intended by the user but is mounted on the mobile phone 10, or the speaker 11 may be blocked. For example, during a phone call, the user makes the phone 10 close to the face and makes a call. At this time, the touch sensor 19 near the microphone 15 is touched by the user's face or mouth, or touches the proximity sensor. The face or mouth may be sensed. In this case, although the user does not intend, the user's voice input may be blocked.

In order to prevent this, the call reception signal may be blocked until the user performs an additional operation before or after the user takes the aforementioned gesture during the call.

For example, as shown in FIG. 7, a specific menu such as the "voice block" menu 20 is displayed, the user selects the menu through touch or physical button operation, and then performs one of the gestures described above to block the user's voice. Can be configured.

In another embodiment, the user's voice is blocked by placing a physical button on the mobile phone 10, for example, a physical button on the side of the mobile phone 10, and performing the aforementioned gestures while pressing a specific button among the physical buttons. can do.

In an embodiment according to the present invention, when a user inputs the same gesture as the gesture of the above-described embodiment while the input of the user voice is blocked, the voice input may be restored again.
