Description

  The present invention relates to an electronic device including a panel such as a touch panel. More specifically, the present invention relates to an electronic device that performs predetermined processing such as executing application software (hereinafter referred to as an application) based on an operation on a touch sensor.

  In recent years, a user's operation is detected in a mobile terminal such as a smartphone, an information device such as a tablet PC, a calculator, and a ticket vending machine, a home appliance such as a microwave oven, a television, and a lighting fixture, and an industrial device (FA device). Electronic devices equipped with a touch panel are widely used as members.

  In general, an electronic device equipped with a touch panel displays an image (hereinafter referred to as an “object”) such as an operation key, a button, or an icon on a display screen of a display unit such as a liquid crystal display disposed on the back side of the touch panel. indicate. In such an electronic device, when a user touches a touch panel at a position corresponding to an object displayed on the display screen, the touch panel detects the contact at the position. Therefore, in such an electronic device, a user interface with a high degree of freedom can be realized according to various application software.

  For such a touch panel, various systems such as a resistive film system, a capacitance system, and an optical system are known. However, any type of touch panel detects an operation with a user's finger or a stylus pen, and the touch panel itself is not physically displaced like a push button switch even when touched. For this reason, even if a user performs operation with respect to a touch panel, the feedback with respect to the said operation cannot be obtained.

  Therefore, a feedback method that generates vibration when an operation on the touch panel is detected has been proposed (see, for example, Patent Document 1). Patent Document 1 describes an example in which a piezoelectric element is used as a vibrating portion. The vibration unit can generate vibration by bending the touch panel by expanding and contracting the piezoelectric element. In this way, the input device described in Patent Literature 1 can present a tactile sensation when the user operates the touch panel.

JP 2011-34150 A

  By the way, the inventor vibrates the panel by applying a predetermined electric signal (sound signal) to the piezoelectric element, and transmits the vibration of the panel to the human body to transmit the air conduction sound and the vibration sound to the user. A new panel device with functions was studied. By installing such a piezoelectric element for sound transmission on a panel, an electronic device that transmits sound through the panel can be realized.

  In this way, when the electronic device that vibrates the panel and transmits sound is a communication device such as a mobile phone or a smartphone, the inventor uses the electronic device panel as a usage mode when the user makes a call. It is assumed that the sound is heard by touching the ear.

  However, in the use mode as described above, when the panel of the electronic device is a touch panel that detects contact of the user's finger or the like, when the user makes a call with the electronic device in contact with the ear, the touch panel depends on the user's ear. A contact is detected. For this reason, the electronic device starts executing predetermined processing such as displaying characters or disconnecting a call against the user's intention based on detection of contact with the user's ear on the touch panel. There is a risk that.

  In order to solve such a problem, for example, a proximity sensor is provided in such an electronic device, and even if it is detected that the user's ear or the like is close to or touches the touch panel during a call It is also conceivable to perform control so that predetermined processing is not performed. However, when the user quickly brings an ear or the like close to the touch panel during a call, the proximity sensor or the like may not catch up with the speed at which the proximity is detected. In such a case, there still arises a problem that execution of some processing is started unintentionally by the user's ear or the like touching the touch panel during a call.

  An object of the present invention made in view of such circumstances is to provide an electronic apparatus capable of reducing the possibility of executing a process unintended by a user.

(First embodiment)
Hereinafter, embodiments of an electronic apparatus according to a first embodiment of the present invention will be described with reference to the drawings. The electronic device according to the present invention can be a mobile phone, a smartphone, a tablet PC, or the like provided with a touch panel. However, the present invention is not limited to these portable devices, and can be various electronic devices such as home appliances, industrial devices (FA devices), and dedicated terminals provided with a touch panel.

  FIG. 1 is a functional block diagram of an electronic apparatus according to the first embodiment of the present invention.

  As shown in FIG. 1, the electronic device 1 according to the first embodiment of the present invention includes a panel 10, a display unit 20, a first piezoelectric element 31, a second piezoelectric element 32, a press detection unit 35, an input unit 40, and a control. A unit 50 and a microphone 80 are provided.

  The panel 10 can be a touch panel that detects contact, a cover panel that protects the display unit 20, or the like. The panel 10 is preferably formed of a synthetic resin such as glass or acrylic. The panel 10 is made of, for example, glass or a synthetic resin such as acrylic. The shape of the panel 10 may be a plate shape. The panel 10 may be a flat plate or a curved panel whose surface is inclined smoothly. When the panel 10 is a touch panel, it detects contact of a user's finger or stylus pen. The detection method of the touch panel should be an arbitrary method such as a capacitance method, a resistance film method, an optical method, a surface acoustic wave method (or an ultrasonic method), an infrared method, an electromagnetic induction method, and a load detection method. Can do.

  In addition, the panel 10 is preferably arranged in a housing or the like so as to be vibrated by an appropriate means. That is, if all the edges of the panel 10 are firmly fixed to a housing or the like, the amplitude when the panel 10 is vibrated cannot be gained, and a good tactile sensation cannot be presented to the user. Therefore, for example, the panel 10 is disposed in the housing via an elastic member, or the panel 10 is partially fixed to the housing, so that the panel 10 can be vibrated and disposed in the housing. It is preferable to install them.

  When the panel 10 is formed of a member such as a touch panel, the panel 10 detects contact with a touch surface such as a user's finger or stylus pen, and outputs information on the position of the contact. With this output, the control unit 50 can acquire the position of the contact detected by the panel 10. Therefore, in this embodiment, the panel 10 can be a contact detection unit.

  The display unit 20 is a display device such as a liquid crystal display, an organic EL display, or an inorganic EL display. The display unit 20 can display various information, images, and objects such as keys and buttons on the screen. The display unit 20 is provided on the back surface of the panel 10. The display unit 20 is disposed on the back surface of the panel 10 by a bonding member (for example, an adhesive). The display unit 20 may be disposed apart from the panel 10 and supported by the housing of the electronic device 1. In the case where the panel 10 is configured with a member such as a touch panel, it is preferable that the panel 10 is configured with, for example, a transparent member and the display unit 20 is disposed on the back side thereof. In this case, an object such as a key or a button can be drawn and displayed on the display unit 20 and an operation of the user pressing the object can be detected on the panel 10. Such display on the display unit 20 can be performed under the control of the control unit 50.

  The first piezoelectric element 31 and the second piezoelectric element 32 are elements that expand or contract or bend according to an electromechanical coupling coefficient of a constituent material by applying an electric signal (voltage). These piezoelectric elements are made of, for example, ceramic or quartz. The first piezoelectric element 31 and the second piezoelectric element 32 can be unimorphs, bimorphs, or stacked piezoelectric elements. The stacked piezoelectric element includes a stacked bimorph element in which bimorphs are stacked (for example, 16 layers or 24 layers are stacked). The laminated piezoelectric element is composed of a laminated structure of a plurality of dielectric layers made of, for example, PZT (lead zirconate titanate) and electrode layers arranged between the plurality of dielectric layers. A unimorph expands and contracts when an electric signal (voltage) is applied, and a bimorph bends when an electric signal (voltage) is applied.

  The first piezoelectric element 31 and the second piezoelectric element 32 are preferably disposed on the back surface of the panel 10 (the surface on the inner side of the electronic device 1). The first piezoelectric element 31 and the second piezoelectric element 32 are attached to the panel 10 by a joining member (for example, double-sided tape). Further, the first piezoelectric element 31 and the second piezoelectric element 32 may be attached to the panel 10 via an intermediate member (for example, a sheet metal). The first piezoelectric element 31 and the second piezoelectric element 32 are arranged on the back surface of the panel 10 and are separated from the inner surface of the housing by a predetermined distance. It is preferable that the first piezoelectric element 31 and the second piezoelectric element 32 be separated from the surface on the inner side of the housing by a predetermined distance even in a stretched or bent state. That is, the distance between the first piezoelectric element 31 and the second piezoelectric element 32 and the inner surface of the housing is set to be larger than the maximum deformation amount of the first piezoelectric element 31 and the second piezoelectric element 32. Is preferred.

  In the present embodiment, the first piezoelectric element 31 is a piezoelectric element mainly used for presenting a tactile sensation. Therefore, it is desirable that the first piezoelectric element 31 is designed so as to have a frequency characteristic suitable for presenting a predetermined tactile sensation based on the electrical signal from the control unit 50. In the present embodiment, the first piezoelectric element 31 need not be provided when the electronic device 1 has a specification that does not present tactile sensation. On the other hand, in the present embodiment, the second piezoelectric element 32 is a piezoelectric element mainly used for transmitting sound. Therefore, it is desirable that the second piezoelectric element 32 is designed so as to have a frequency characteristic suitable for transmitting a predetermined sound based on an electric signal from the control unit 50.

  The pressure detection unit 35 detects a pressure on the panel 10 and, for example, an element such as a strain gauge sensor or a piezoelectric element whose physical or electrical characteristics (strain, resistance, voltage, etc.) change according to the pressure. To configure. When the pressure detection unit 35 is configured using, for example, a piezoelectric element or the like, the piezoelectric element of the pressure detection unit 35 is a magnitude of a load (force) relating to a pressure on the panel 10 (or a magnitude of the load (force). The magnitude of the voltage (voltage value (hereinafter referred to as data based on pressure)), which is an electrical characteristic, changes in accordance with the speed (acceleration) at which the voltage changes. Note that the data based on the pressure may be the magnitude of the load applied to the pressure, the power value, the resistance value, or the like instead of the voltage value.

  Further, the pressure detection unit 35 can be configured integrally with the first piezoelectric element 31. That is, the first piezoelectric element 31 for presenting a tactile sensation can be a piezoelectric element that also functions as the press detection unit 35. This is because the piezoelectric element generates a voltage when pressure is applied and deforms when the voltage is applied.

  Furthermore, the press detection part 35 can be comprised according to the contact detection system in the panel 10. FIG. For example, in the case of the resistance film type, the size of the resistance corresponding to the size of the contact area is associated with the load (force) of pressing against the panel 10, so that a configuration without using a strain gauge sensor or a piezoelectric element is used. can do. Alternatively, in the case of the electrostatic capacitance method, the capacitance can be configured without using a strain gauge sensor, a piezoelectric element, or the like by associating the size of the electrostatic capacitance with a load (force) of pressing against the panel 10.

  The input unit 40 detects a user's input operation and includes, for example, operation buttons (operation keys). In addition, when the panel 10 is a touch panel, the panel 10 can also detect the contact from a user. An electrical signal based on the input operation detected by the input unit 40 is sent to the control unit 50.

  The control unit 50 is a processor that controls the electronic device 1. The controller 50 applies a predetermined electrical signal to the first piezoelectric element 31 and the second piezoelectric element 32. The controller 50 can drive the first piezoelectric element 31 and the second piezoelectric element 32 by applying predetermined electrical signals to the first piezoelectric element 31 and the second piezoelectric element 32, respectively.

  Further, the control unit 50 applies an electrical signal to the second piezoelectric element 32, drives the second piezoelectric element 32, and controls sound output. As described above, when the sound output is controlled by driving the second piezoelectric element 32, the control unit 50 is based on a sound output trigger from a predetermined application or the like (based on a sound signal (sound signal) or the like). It can be controlled to drive the second piezoelectric element 32.

  The voltage applied by the control unit 50 to the second piezoelectric element 32 is higher than ± 5 V, which is an applied voltage of a so-called panel speaker for the purpose of conducting sound by air conduction sound, not vibration sound, for example. , ± 15V. Thus, even when the user presses the panel 10 against his / her body with a force of 3N or more (5N to 10N), for example, the panel 10 is caused to vibrate sufficiently, The vibration sound transmitted through can be generated. Note that how much applied voltage is used can be appropriately adjusted according to the fixing strength of the panel 10 with respect to the casing or the support member or the performance of the first piezoelectric element 31 or the second piezoelectric element 32.

  When the control unit 50 applies an electrical signal to the first piezoelectric element 31 and the second piezoelectric element 32, the first piezoelectric element 31 and the second piezoelectric element 32 to which the electrical signal is applied extend and contract in the long side direction of each element. . At this time, the panel 10 to which the first piezoelectric element 31 and the second piezoelectric element 32 are attached is deformed according to the expansion and contraction of the first piezoelectric element 31 and the second piezoelectric element 32, and the panel 10 vibrates.

  When the second piezoelectric element 32 expands and contracts and the panel 10 vibrates, the panel 10 generates air conduction sound, and when the user touches a part of the body (for example, the cartilage of the outer ear), A vibration sound transmitted through a part is generated. The control unit 50 transmits the air conduction sound and the vibration sound to the object in contact with the panel 10. For example, the control unit 50 can apply an electric signal corresponding to an audio signal related to the voice of the other party to the second piezoelectric element 32, for example, and generate air conduction sound and vibration sound corresponding to the audio signal. The audio signal may relate to a ringing melody or a music piece including music. Note that the audio signal applied to the electrical signal may be based on music data stored in the internal memory of the electronic device 1, or music data stored in an external server or the like is reproduced via a network. May be.

  The panel 10 vibrates not only in the attachment region to which the second piezoelectric element 32 is attached, but also in a region away from the attachment region. The panel 10 has a plurality of locations that vibrate in a direction intersecting with the main surface of the panel 10 in a region where the vibration is generated, and the amplitude value of the vibration at each of the plurality of locations increases from plus to minus with time. And vice versa. At a certain moment, the panel 10 vibrates in such a manner that a portion having a relatively large vibration amplitude and a portion having a relatively small vibration amplitude are distributed randomly or periodically throughout the panel 10 at first glance. That is, vibrations of a plurality of waves are detected over the entire area of the panel 10. Even when the user presses the panel 10 against his / her body with a force of 5N to 10N, for example, the control unit 50 applies the second piezoelectric element 32 to suppress the above-described vibration attenuation of the panel 10. The applied voltage may be ± 15V. Therefore, the user can hear the sound by bringing his / her ear into contact with an area away from the above-described panel 10 mounting area.

  In addition, the control unit 50 notifies the control unit 50 of the data based on the press by the press detection unit 35 or detects the data based on the press of the press detection unit 35 by the control unit 50. Get data based on. That is, the control unit 50 acquires data based on the pressure on the panel 10 from the press detection unit 35.

  Furthermore, in this embodiment, when the control unit 50 executes (acts) a call function, the user of the electronic device 1 can make a call with a user such as another electronic device. When a communication function is executed in the electronic device 1, a communication unit 90 to be described later performs communication with a base station or another communication device by wired or wireless. At this time, in the electronic device 1, each functional unit related to communication, such as the second piezoelectric element that outputs sound and the microphone 80, is appropriately used. In addition, the control unit 50 can detect that the electronic device 1 is executing a call function. Here, various modes in which the control unit 50 detects the execution of the call function can be assumed. Typically, for example, the control unit 50 can detect that a call function is being executed (activated) when an application for making a call is being executed (activated).

  Alternatively, when detecting that the control unit 50 is driving the second piezoelectric element 32 for transmitting sound during a call, the control unit 50 can detect the execution of the call function. Furthermore, when a voice of a user or the like is detected by the microphone 80 during a call, the control unit 50 may detect the execution of the call function. Alternatively, when the driving of the second piezoelectric element 32 for transmitting sound is detected during a call, the control unit 50 can detect the execution of the call function. Further, by providing a proximity sensor such as an optical sensor, for example, when it is detected that the user's ear or the like has approached the panel 10, the control unit 50 can detect the execution of the call function. Further, for example, by providing an acceleration sensor, for example, when it is detected that the electronic device 1 has approached the user's ear or the like, the control unit 50 can detect the execution of the call function.

  The microphone 80 collects ambient sounds such as a user's speech. The sound collected by the microphone 80 is sent to the control unit 50 as an electrical signal.

  When the electronic device 1 is a communication device, the communication unit 90 enables communication with a base station or another communication device by wire or wireless. When the electronic device 1 communicates with a base station or another communication device wirelessly, the communication unit 90 includes the communication antenna.

  FIG. 2 is a diagram illustrating an example of a mounting structure of the electronic device 1 according to the first embodiment. 2A is a front view, and FIG. 2B is a cross-sectional view taken along the line CC in FIG. 3A.

  The electronic device 1 shown in FIG. 2 is a smartphone in which a touch panel, which is a glass plate, is arranged as a panel 10 on the front surface of a housing 60 (for example, a metal or resin case). Panel 10 and input unit 40 are supported by housing 60. In addition, the display unit 20, the first piezoelectric element 31, and the second piezoelectric element 32 are bonded to the panel 10 via bonding members 70. In the example shown in FIG. 2A, as described above, the first piezoelectric element 31 is shown as a piezoelectric element that also functions as the press detection unit 35. In the example shown in FIG. 2A, the first piezoelectric element 31 and the second piezoelectric element 32 are bonded to the back side of the panel. In order to show this, in FIG. 2A, the first piezoelectric element 31 and the second piezoelectric element 32 are indicated by broken lines. The joining member 70 is an adhesive having a thermosetting property or an ultraviolet curable property, a double-sided tape, or the like, and may be, for example, an optical elastic resin that is a colorless and transparent acrylic ultraviolet curable adhesive. The panel 10, the display part 20, the 1st piezoelectric element 31, and the 2nd piezoelectric element 32 are each substantially rectangular shapes. Further, a microphone 80 is arranged around a predetermined position on the panel 10, typically around a position facing the second piezoelectric element 32 with reference to the central portion of the panel 10. The microphone 80 is not shown in FIG.

  As shown in FIG. 2A, the display unit 20 is disposed approximately at the center of the panel 10 in the short direction. Further, the first piezoelectric element 31 and the second piezoelectric element 32 are separated from the end in the longitudinal direction of the panel 10 by a predetermined distance, and in the vicinity of the end, the first piezoelectric element 31 and the second piezoelectric element 32 are provided. Are arranged so that the longitudinal direction of the panel is along the short side of the panel 10.

  In FIG. 2, the display unit 20, the first piezoelectric element 31, and the second piezoelectric element 32 are shown to be arranged side by side in a direction parallel to the surface on the back side of the panel 10. The arrangement is not limited to the illustrated example. For example, at least one of the first piezoelectric element 31 and the second piezoelectric element 32 can be arranged in parallel to the longitudinal direction of the electronic apparatus 1 (the longitudinal direction in FIG. 2A). In short, in the present embodiment, the first piezoelectric element 31 and the second piezoelectric element 32 can be arbitrarily configured so as to be able to transmit vibration to the panel 10 by being attached to the panel 10.

  2 shows a configuration in which the display unit 20 is bonded to the back side of the panel 10 via the bonding member 70, but the arrangement of the display unit 20 is not limited to the illustrated example. . For example, the display unit 20 can be adhered to the back surface side of the panel 10 without using the joining member 70, or can be disposed inside the housing 60 instead of being adhered to the panel 10. . When the display unit 20 is arranged inside the housing 60, the display unit 20 is arranged and fixed directly inside the housing 60, or is used for a substrate or a display unit arranged inside the housing 60. It can be fixed to a holder or the like. As shown in FIG. 2, when the display unit 20 is arranged on the back side of the panel 10, when a touch panel is configured by the panel 10 and the display unit 20, a free user interface is displayed on the display unit 20, This operation can be detected by the panel 10. In FIG. 2A, the display unit 20 is indicated by a broken line, so that the display unit 20 is adhered to the back side of the panel 10.

  In FIG. 2, other than the display unit 20, the first piezoelectric element 31, the second piezoelectric element 32, the input unit 40, the joining member 70, and the microphone 80, the space closed by the housing 60 and the panel 10 is used. The illustration of the element is omitted. Therefore, the electronic device 1 can include elements such as the control unit 50 and various substrates or components other than those shown in FIG. In FIG. 2A, an area on the panel 10 where the display by the display unit 20 does not need to be transmitted (that is, an area where the panel 10 and the display unit 20 do not overlap) is an area near the edge of the panel 10. It is preferred to paint or cover with a bezel. In this way, it is possible to prevent the first piezoelectric element 31, the second piezoelectric element 32, and the like from being visible from the outside of the electronic device 1.

  Next, processing performed by the control unit 50 according to the present embodiment will be described.

  FIG. 3 is a flowchart for explaining processing in the present embodiment. In the present embodiment, the control unit 50 performs control so as to perform predetermined processing based on detection of contact by the panel 10 when the call function is not being executed. That is, when the call function is not being executed, when it is detected that the user's finger or the like has touched the panel 10, the control unit 50 performs control so as to perform a predetermined process. At this time, when contact is detected with the panel 10 at a position corresponding to a position where an object such as a predetermined key or button is displayed on the display unit 20, a predetermined process associated with the object is performed. Is preferred.

  When the process of the present embodiment is started, the control unit 50 determines whether or not the panel 10 has detected contact as described above (step S11). If the panel 10 detects contact in step S11, the control unit 50 determines whether or not the execution of the call function is detected in the electronic device 1 (step S12).

  If the execution of the call function is not detected in step S12, that is, if the call is not in progress, the control unit 50 controls to perform a predetermined process based on the detected contact (step S13). For example, when contact is detected on the panel 10 at a position corresponding to the position where the character input key object is displayed on the display unit 20, the control unit 50 performs a process of displaying the character on the display unit 20. To control. Further, for example, when contact is detected on the panel 10 at a position corresponding to the position where the call or disconnect object is displayed on the display unit 20, the control unit 50 performs a process of starting or disconnecting the call, respectively. Control. Thus, in the present embodiment, the control unit 50 performs control so as to perform a predetermined process based on detection of contact by the panel 10.

  On the other hand, if contact is detected in step S11 and execution of the call function is detected in step S12, that is, if a call is in progress, the process proceeds to step S14. In step S <b> 14, the control unit 50 performs control so as to perform the predetermined process based on detection of contact by the panel 10 and detection of press by the press detection unit 35. That is, in the present embodiment, when the control unit 50 detects the execution of the call function, it is preferable to perform control so that the predetermined processing is not performed based only on detection of contact by the panel 10.

  In step S14, when the control unit 50 detects the execution of the call function, it is preferable to perform control so that the predetermined process is performed when data based on the pressure detected by the pressure detection unit 35 satisfies a predetermined standard. It is. Here, the predetermined standard to be satisfied by the data based on the pressure on the panel 10 is set such that the predetermined process is not performed as long as the user's ear or the like touches the panel 10 lightly.

  Such a predetermined standard can be set in advance and stored in the control unit 50 or the like. In addition, it is preferable that such a predetermined standard can be changed later in consideration of the user's comfort. Furthermore, it may be calculated from data based on a normal operation of the user on the panel 10 and / or a normal pressure when the user puts an ear or the like on the panel.

  In short, in the present embodiment, the control unit 50 does not perform a predetermined process to the extent that the panel 10 detects a light contact during a call, and only performs the predetermined process when the pressure detected by the pressure detection unit 35 is somewhat strong. To do. As described above, according to the electronic device 1 according to the present embodiment, even when the user touches the panel 10 with the user's ear or the like during a call, the possibility that a predetermined process is executed based on the contact is reduced. To do. Therefore, according to the electronic device 1 according to the present embodiment, it is possible to reduce the possibility that a process unintended by the user is executed.

  The control unit 50 controls the first piezoelectric element 31 to generate a tactile sensation by generating a predetermined vibration when the execution of the call function is detected and the data based on the press satisfies a predetermined reference. May be. Here, the predetermined reference can be appropriately set according to the load characteristic when the object is pressed.

  Further, when the first piezoelectric element 31 also serves as the pressure detection unit 35, the first piezoelectric element 31 vibrates by driving the piezoelectric element when the voltage magnitude (voltage value (data)) of the piezoelectric element satisfies a predetermined standard. Can also be generated. Here, when the voltage level (voltage value (data)) of the piezoelectric element satisfies a predetermined reference, the voltage value (data) may reach a predetermined reference value, It may be when the value (data) exceeds a predetermined reference value or when a voltage value (data) equal to the predetermined reference value is detected.

(Second Embodiment)
Next, an electronic apparatus according to a second embodiment of the invention will be described. The electronic device 2 according to the second embodiment changes the control by the control unit 50 in the electronic device 1 according to the first embodiment. Therefore, the second embodiment of the present invention can be basically implemented by an electronic device having the same configuration as the electronic device 1 described in the first embodiment. For this reason, the description which becomes the same as 1st Embodiment is abbreviate | omitted.

  Also in the second embodiment, the control unit 50 controls to output sound by driving the second piezoelectric element 32. Thereby, in the electronic device 2, the 2nd piezoelectric element is the same as that of 1st Embodiment about the point which can implement | achieve the function which outputs an audio | voice and transmits the said audio | voice to a user.

  In the first embodiment, when a contact with the panel 10 is detected except during a call, a predetermined process is performed, and during the call, data based on the pressure detected by the pressure detection unit 35 satisfies a predetermined standard. Control was performed so as to perform predetermined processing. In the second embodiment, the predetermined processing is performed when the data based on the pressure detected by the pressure detection unit 35 satisfies a predetermined standard regardless of whether the communication is in progress. Is set higher than when not in a call.

  FIG. 4 is a flowchart for explaining processing in the present embodiment.

  When the process of the second embodiment starts, the control unit 50 sets a predetermined value P1 as the above-described predetermined reference (step S21). The predetermined reference P1 is set in advance with a value in consideration of data based on a pressure when the user performs a normal operation, so that a reference with an excessively low value is not set, and the setting can be changed thereafter. Is desirable.

  By setting a value (for example, an average value) in consideration of data based on the pressure when the user performs a normal operation as the predetermined reference P1, the predetermined reference P1 is used when the user touches lightly unintentionally. Is prevented from being performed. In this way, the pressure sense of the user's fingertip is stimulated in a state where the data based on the pressure detected by the pressure detection unit 35 satisfies the predetermined reference P1. In this state, the first piezoelectric element 31 is driven to vibrate with an appropriate amplitude and frequency, so that a real click as when a switch such as a push button switch (push button switch) is actually pressed is used. A tactile sensation can be presented. In this case, even if the push button switch is drawn as an image on the touch sensor, the user performs a touch operation on the panel 10 while obtaining a realistic click feeling similar to that when the actual push button switch is operated. It can be performed.

  When the predetermined reference P1 is set in step S21, the control unit 50 determines whether or not the panel 10 has detected contact (step S22). When the panel 10 detects contact in step S22, the control unit 50 determines whether or not the execution of the call function is detected in the electronic device 2 (step S23).

  If execution of the call function is not detected in step S23, that is, if the call is not in progress, the process proceeds to step S24. In step S24, the control unit 50 determines whether or not the data based on the pressure on the panel 10 satisfies a predetermined reference P1. When the data based on the pressure on the panel 10 does not satisfy the predetermined reference P1 in step S24, the control unit 50 returns to step S21 and continues the process.

  On the other hand, when the data based on the pressure on the panel 10 satisfies the predetermined reference P1 in step S24, the control unit 50 controls to perform a predetermined process based on the detected contact (step S25). The predetermined process performed in step S25 is the same as the predetermined process in step S13 of FIG. 3 described in the first embodiment. As in the first embodiment, when the execution of the call function is detected and the data based on the press satisfies a predetermined reference P1, the control unit 50 causes the first piezoelectric element 31 to generate a predetermined vibration. It may be controlled to present a tactile sensation.

  If execution of the call function is detected in step S23, that is, if a call is in progress, the control unit 50 sets the predetermined reference set in P1 to P2, which is a value higher (larger) than P1 ( Step S26). Here, P2 that is a value higher than P1 is set to a value that can be used as a reference so that the predetermined processing is not performed when the user's ear or the like touches the panel 10 to some extent.

  If P2 which is higher than P1 is set as the predetermined reference in step S26, the control unit 50 determines whether or not the data based on the pressure on the panel 10 satisfies the predetermined reference P2 (step S27). When the data based on the pressure on the panel 10 does not satisfy the predetermined reference P2 in step S27, the control unit 50 returns to step S21 and continues the process.

  On the other hand, when the data based on the pressure on the panel 10 satisfies the predetermined reference P2 in step S27, the control unit 50 performs a predetermined process (step S25). As in the first embodiment, when the execution of the call function is detected and the data based on the press satisfies a predetermined reference P2, the control unit 50 causes the first piezoelectric element 31 to generate a predetermined vibration. It may be controlled to present a tactile sensation.

  Thus, in the present embodiment, the control unit 50 performs control so that predetermined processing is performed when data based on the pressure on the panel 10 satisfies the predetermined reference P1. However, in the present embodiment, when detecting the execution of the call function, the control unit 50 controls the predetermined reference P1 to be set higher (P2). In this case, when the control unit 50 detects the execution of the second piezoelectric element 32 for transmitting sound, it is preferable to perform control so that the predetermined reference is set high. Further, it is preferable that the control unit 50 performs control so as to drive the first piezoelectric element 31 for presenting a tactile sensation when data based on the pressure on the panel 10 satisfies a predetermined reference P1 or P2.

  According to the electronic device 2 according to the present embodiment, even if the user touches the panel 10 with the user's ear or the like during a call, the possibility that a predetermined process is executed based on the contact is reduced. Therefore, according to the electronic device 2 according to the present embodiment, it is possible to reduce the possibility that a process unintended by the user is executed. Furthermore, according to the electronic device 2 according to the present embodiment, when the call function is not being executed, even if the user touches the panel 10 lightly unintentionally, the predetermined process is not executed. Therefore, it is possible to further reduce the possibility of executing a process not intended by the user.

  Although the present invention has been described based on the drawings and examples, it should be noted that those skilled in the art can easily make various modifications and corrections based on the present disclosure. Therefore, it should be noted that these variations and modifications are included in the scope of the present invention. For example, functions included in each component can be rearranged so as not to be logically contradictory, and a plurality of components can be combined into one or divided.

  For example, in each of the above-described embodiments, an aspect has been described in which an object is displayed on the display unit 20 disposed on the back side of the panel and the panel 10 detects a user's contact. However, the present invention is not limited to such an aspect, and can be applied to an aspect in which an object is directly printed on the panel 10 with ink or the like without having the display unit 20, for example. .

  Moreover, in the said embodiment, the case where the contact with respect to the said panel 10 was detected using the panel 10 was demonstrated. That is, in the above embodiment, the panel 10 has been described assuming a member such as a so-called touch sensor. However, the touch panel used in the electronic device according to the present invention may be any as long as it can be touched by a contact object such as a user's finger or a stylus pen.

  For example, the panel used for the electronic apparatus according to the present invention can be a member that does not detect the position of contact of the contact object with the panel (that is, does not have a sensing function). In the electronic device having such a configuration, for example, by providing a pressure detection unit that detects pressure on the panel, it can be determined that the panel is contacted based on the pressure detected by the pressure detection unit. .

  Further, the electronic device 1 described above can transmit air conduction sound and vibration sound transmitted through a part of the user's body (for example, cartilage of the outer ear) to the user by the vibration of the panel 10. . Therefore, when outputting a sound having a volume equivalent to that of a conventional dynamic receiver, the sound transmitted to the periphery of the electronic device 1 due to the vibration of the air due to the vibration of the panel 10 is less than that of the dynamic receiver. Therefore, it is suitable, for example, when listening to a recorded message on a train or the like.

  In addition, since the electronic device 1 described above transmits vibration sound by vibration of the panel 10, even if the user wears an earphone or a headphone, for example, by bringing the electronic device 1 into contact with the user, the user can Sounds can be heard through headphones and body parts.

  The electronic device 1 described above transmits sound to the user by the vibration of the panel 10. Therefore, when the electronic device 1 does not include a separate dynamic receiver, it is not necessary to form an opening (sound emission port) for sound transmission in the housing 60, and the waterproof structure of the electronic device 1 can be simplified. In addition, when the electronic device 1 is provided with a dynamic receiver, the sound emission port is preferably closed by a member that allows gas to pass but not liquid. An example of the member that allows gas to pass but not liquid is Gore-Tex (registered trademark).

  In the above-described embodiment, the control unit 50 performs control so as to perform predetermined processing based on detection of contact by the panel 10 and detection of press by the press detection unit 35 during execution of the call function. However, when driving the piezoelectric element 32 for transmitting the sound attached to the panel 10, the control unit 50 performs predetermined processing based on detection of contact by the panel 10 and detection of press by the press detection unit 35. You may control to perform.

  Further, when the control unit 50 performs control so as to perform a predetermined process based on the detection of contact by the panel 10, the control unit 50 is based on the detection of the press by the press detection unit 35 during the execution of the call function. You may control to perform a predetermined process. In this case, the control unit 50 may perform control so that predetermined processing is not performed based on detection by the panel 10 during execution of the call function.

  In addition, when the piezoelectric element 32 for transmitting sound is being driven, the control unit 50 may perform control so as to perform a predetermined process based on detection of pressing by the panel 10. In this case, the control unit 50 may perform control so that predetermined processing is not performed based on detection by the panel 10 when the piezoelectric element 32 for transmitting sound is being driven.

  In addition, the control unit 50 performs control so that predetermined processing is performed when the data based on the press satisfies a predetermined standard, and the sound is generated by driving the piezoelectric element 32 for transmitting sound during execution of the call function. When performing the control to output, the control unit 50 may perform control so as to set a predetermined reference high when driving the piezoelectric element 32 for transmitting sound.
