  As shown in FIG. 1, a combination 1 according to an embodiment of the present invention includes an electronic device 100 and an attachment member 3 for the electronic device 100 (hereinafter simply referred to as “attachment member 3”). Composed. The attachment member 3 is formed to be detachable from the electronic device 100. FIG. 1 shows a state where the attachment member 3 is attached to the electronic device 100. In the present embodiment, by attaching the attachment member 3 to the electronic device 100, the user generates air conduction sound and vibration sound transmitted through a part of the human body not from the electronic device 100 but from the attachment member 3. I can hear you.

  The electronic device 100 is, for example, a mobile phone (smart phone), and includes a touch panel 110, a microphone 120, a speaker 130, and an input unit 140.

  In the present embodiment, the touch panel 110 will be described as including a touch sensor and a display unit. Typically, the touch panel 110 includes a touch sensor that detects contact by a user, and can be configured such that a display unit is disposed on the back side of the touch sensor. The shape of the touch panel 110 may be a plate shape. The touch panel 110 may be a flat plate or a curved panel whose surface is smoothly inclined. The touch sensor of the touch panel 110 detects contact of a user's finger, pen, stylus pen, or the like. As a detection method of the touch sensor, an arbitrary method such as a capacitance method, a resistance film method, a surface acoustic wave method (or an ultrasonic method), an infrared method, an electromagnetic induction method, a load detection method, or the like can be used.

  The display unit of the touch panel 110 is a display device such as a liquid crystal display, an organic EL display, or an inorganic EL display. This display part is arrange | positioned by the joining member (for example, adhesive agent) at the back side of a touch sensor. The display unit may be disposed apart from the touch sensor and supported by the housing of the electronic device 100.

  The microphone 120 collects sound during a call or the like through a hole formed in the casing of the electronic device 100. The microphone 120 is preferably disposed from the back side of the casing of the electronic device 100 (inside the electronic device 100). The speaker 130 can be a dynamic receiver that outputs sound during a call or the like through an opening formed in the housing of the electronic device 100. The speaker 130 is also preferably arranged from the back side of the casing of the electronic device 100 (inside the electronic device 100). When a voice call is performed using the electronic device 100, the user can listen to the sound output from the speaker 130 by placing the speaker 130 on the ear. The user can make a voice call with a call partner or the like by positioning the microphone 120 near the mouth with the speaker 130 in contact with the ear.

  The input unit 140 receives an operation input from a user, and includes, for example, an operation button (operation key). Note that the input unit 40 is not limited to the keys installed at the three locations shown in FIG. 1, and can be any number of keys, buttons, etc. disposed at any location. The touch panel 110 can also accept an operation input from the user by detecting a contact from the user.

  FIG. 2 is a diagram illustrating a state in which the combination 1 illustrated in FIG. 1 is separated into the electronic device 100 and the attachment member 3. That is, FIG. 2 shows a state where the attachment member 3 is removed from the electronic device 100.

  As shown in FIG. 2, the elements that can be seen in plan view from above in the electronic device 100 are the same as the components described in FIG. 1. That is, as illustrated in FIG. 2, the electronic device 100 includes a touch panel 110, a microphone 120, a speaker 130, and an input unit 140. Furthermore, as shown in FIG. 2, electronic device 100 includes connection terminal 150 (hereinafter simply referred to as “connection terminal 150”) of electronic device 100 on the right side when viewed in a plan view. The connection terminal 150 may be, for example, a connector socket or a receptacle.

  The attachment member 3 is a member that can be attached to the electronic device 100, and can be various members such as a jacket, a case, a cover, a cradle, an attachment, or a skin for the electronic device 100. In addition, in the following description, the attachment member 3 which concerns on this embodiment demonstrates an aspect like the jacket for the electronic devices 100. FIG. However, the attachment member 3 is not limited to a member that covers most of the casing of the electronic device 100 in order to prevent the electronic device 100 from being damaged, such as a jacket that is attached to the electronic device main body. For example, the attachment member 3 according to the present embodiment may be a relatively small member that is attached to a surface (for example, a side surface or a top surface) on which the housing connection terminal 150 (connector) is mounted in the electronic device 100. it can. Even when the mounting member 3 is relatively small, the mounting member 3 may be a plate-like member or a member having another shape as long as it can generate air conduction sound and vibration sound.

  As shown in FIG. 2, the attachment member 3 according to the present embodiment described below includes a main body portion 5 of the attachment member. The main body portion 5 includes an electronic device housing portion 7 that houses the electronic device 100. The vibration reducing member 9 is formed.

  The electronic device accommodating portion 7 is formed so as to accommodate the main body of the electronic device 100 when the attachment member 3 is attached to the electronic device 100. The vibration reducing member 9 is an elastic member that can be disposed in at least a part of the portion of the mounting member 3 that contacts the housing of the electronic device 100 when the mounting member 3 is mounted to the electronic device 100. For example, it can be composed of silicon rubber (silicon rubber). Typically, the vibration reducing member 9 is preferably disposed on at least a part of the side wall and the bottom surface of the electronic device housing portion 7 in the mounting member 3. A mode in which the vibration reducing member 9 reduces vibration will be described later.

  Furthermore, the attachment member 3 includes a connection terminal 20 (hereinafter simply referred to as “connection terminal 20”) of the attachment member 3 on the inner wall on the right side in a state where the electronic device housing portion 7 is viewed in plan. The connection terminal 20 can be, for example, a connector plug. The connection terminal 20 is configured to be connected to the connection terminal 150 when the attachment member 3 is attached to the electronic device 100. In the present embodiment, the attachment member 3 can receive audio signals and various control signals from the electronic device 100 by being electrically connected to the electronic device 100 through the connection terminals 20 and 150. Further, the attachment member 3 is electrically connected to the electronic device 100, whereby a voltage can be applied from the electronic device 100 via the connection terminals 20 and 150. The connection terminals 20 and 150 may employ various connection members such as microUSB, an earphone jack, or an original standard connection terminal according to the input / output interface of the electronic device 100.

  The connection terminal 20 is disposed at a position where the connection member 20 is fitted to the connection terminal 150 when the attachment member 3 is attached to the electronic device 100. Since the position of the connection terminal 150 in the electronic device 100 is assumed to be different depending on various electronic devices, the mounting member 3 is designed and sold for each of the various electronic devices 100 such as a smartphone jacket or case. Is desirable.

  When attaching the attachment member 3 to the electronic device 100, the electronic device 100 is inclined with respect to the electronic device housing portion 7 so that the connection terminal 20 is first inserted into the connection terminal 150, and then the electronic device 100. It is preferable that the entirety is accommodated in the electronic device accommodating portion 7. At this time, by attaching at least one material of the electronic device accommodating portion 7 and the vibration reducing member 9 of the attachment member 3 to have some elasticity, the electronic device 100 is attached when the entire electronic device 100 is accommodated in the electronic device accommodating portion 7. The member 3 can be slightly deformed or stretched. Preferably, the electronic device 100 is formed so that the end on the inner wall top side of the electronic device housing portion 7 protrudes slightly inside, and the electronic device 100 is completely housed in the electronic device housing portion 7. It is desirable to configure so that does not fall off the mounting member 3. In addition, the attachment member 3 can be removed from the electronic device 100 even after the attachment member 3 is attached to the electronic device 100 by slightly deforming or extending the attachment member 3. Thus, in the combination 1 according to this embodiment, the attachment member 3 is configured to be detachable from the electronic device 100.

  FIG. 3 is an exploded perspective view of the mounting member 3 shown in FIG. 2 as viewed from the back side. In FIG. 3, the connection terminal 20 is indicated by a broken line because it exists at a position where it cannot be seen (on the back side with reference to FIG. 3). 4 is a cross-sectional view taken along line AA of the mounting member 3 shown in FIG.

  As shown in FIG. 3, the attachment member 3 viewed from the back side has a panel 10 attached to the main body portion 5 of the attachment member, and FIG. 3 shows a state in which the panel 10 is removed from the attachment member 3. . 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 smoothly inclined. In the state where the mounting member 3 is assembled, the panel 10 is fitted into the edge 11 formed in the main body 5 as shown in FIG. In addition, since various aspects are assumed in the structure which installs the panel 10 in the main-body part 5 of an attachment member, in FIG.3 and FIG.4, illustration about the mechanism which installs the panel 10 in the main-body part 5 is abbreviate | omitted. It is.

  For example, the panel receiving portion may be formed so that the vicinity of the end portion on the inner wall top side of the panel housing portion 13 formed in the main body portion 5 protrudes inward, and the panel 10 is fixed to the panel receiving portion. Good. Alternatively, a member for fixing the panel 10 can be formed at an arbitrary position of the panel accommodating portion 13, and the panel 10 can be fixed on the top surface side of various elements provided in the panel accommodating portion 13. it can. As described above, when the panel 10 is fixed to the main body 5 of the mounting member 3, it is preferable to fix the panel 10 via the joining member 70. The joining member can be a thermosetting or ultraviolet curable adhesive, a double-sided tape, or the like, and may be an optical elastic resin that is a colorless and transparent acrylic ultraviolet curable adhesive, for example.

  As shown in FIGS. 3 and 4, a piezoelectric element 30 as a vibration element is disposed at a predetermined position on the back surface (back surface) of the panel 10. The piezoelectric element 30 is an element that expands or contracts or curves in accordance with an electromechanical coupling coefficient of a constituent material by applying an electric signal (voltage). For these elements, for example, those made of ceramic or quartz are used. The piezoelectric element 30 may be a unimorph, bimorph, or multilayer piezoelectric element. 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. Unimorphs expand and contract when an electrical signal (voltage) is applied, and bimorphs bend when an electrical signal (voltage) is applied.

  The piezoelectric element 30 is attached to the panel 10 by a joining member (for example, double-sided tape). The piezoelectric element 30 may be attached to the panel 10 via an intermediate member (for example, a sheet metal). The piezoelectric element 30 is spaced from the inner surface of the main body 5 by a predetermined distance while being disposed on the back surface of the panel 10. The space thus separated will be referred to as a panel accommodating portion 13 for convenience. The piezoelectric element 30 may be separated from the surface on the inner side of the main body 5 by a predetermined distance even in a stretched or curved state. That is, the distance between the piezoelectric element 30 and the inner surface of the main body 5 is preferably larger than the maximum deformation amount of the piezoelectric element 30. Thus, the attachment member 3 according to the present embodiment has the panel 10 that is a planar portion, and can generate air conduction sound and vibration sound from the panel 10.

  As shown in FIGS. 3 and 4, a circuit board 50 is disposed at a predetermined position in the panel housing part 13 of the main body part 5. The circuit board 50 preferably includes a control unit that is a processor that controls the sound output from the mounting member 3. In addition to the circuit board 50, the panel housing portion 13 of the main body 5 can include various elements such as a spare battery for the electronic device 100.

  The control unit provided in the circuit board 50 controls an electrical signal (voltage corresponding to the audio signal) applied to the piezoelectric element 30 in accordance with the audio signal received from the electronic device 100. The voltage applied to the piezoelectric element 30 by the control of the control unit is, for example, ± 15 V, which is higher than ± 5 V, which is a voltage applied to a so-called panel speaker for the purpose of conducting sound by air conduction sound instead of vibration sound. It's okay. As a result, even when the user presses the panel 10 against his / her body with a force of 3N or more (5N to 10N), for example, sufficient vibration is generated in the panel 10 to Vibrating sound can be generated through the section. Note that how much applied voltage is used can be appropriately adjusted according to the fixing strength of the panel 10 to the casing or the support member or the performance of the piezoelectric element 30. When the control unit controls the piezoelectric element 30 to apply an electrical signal, the piezoelectric element 30 expands or contracts in the longitudinal direction. At this time, the panel 10 to which the piezoelectric element 30 is attached is deformed in accordance with the expansion or contraction or bending of the piezoelectric element 30, and the panel 10 vibrates. For this reason, the panel 10 generates air conduction sound, and also generates vibration sound through a part of the body when the user contacts a part of the body (for example, cartilage of the outer ear). For example, the control unit can control the electrical signal corresponding to the voice signal related to the voice of the other party to be applied to the piezoelectric element 30 to generate air conduction sound and vibration sound corresponding to the voice 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 100, or music data stored in an external server or the like may be reproduced via a network. May be.

  The panel 10 vibrates not only in the attachment region to which the piezoelectric element 30 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 the main surface of the panel 10 in the vibrating region, and the amplitude value of the vibration is increased from positive to negative with time in each of the plurality of locations. Or 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 panel 10. Even when the user presses the panel 10 against his / her body with a force of, for example, 5N to 10N, the control unit applies to the piezoelectric element 30 in order to prevent the above-described vibration of the panel 10 from being attenuated. The voltage to be controlled may be ± 15V. Therefore, the user can hear the sound by bringing his / her ear into contact with a region away from the above-described region where the panel 10 is attached.

  Here, the panel 10 may be approximately the same size as the user's ear. The panel 10 may be larger than the user's ear, as shown in FIG. In this case, when the user listens to the sound, the entire ear is likely to be covered by the panel 10 of the combination 1 (attachment member 3), so that ambient sounds (noise) can hardly enter the ear canal. Panel 10 is an area wider than an area having a length corresponding to the distance from the lower leg of the anti-annulus (lower anti-limb) to the anti-tragus and a width corresponding to the distance from the tragus to the anti-annulus. Should just vibrate. The panel 10 preferably has a length corresponding to the distance between a portion near the upper leg of the ankle ring (upper pair leg) in the ear ring and the earlobe, and a distance between the tragus and a portion near the ear ring in the ear ring. It suffices that a region having a width corresponding to is vibrated. The region having the above length and width may be a rectangular region, or may be an elliptical shape having the above length as the major axis and the above width as the minor axis. The average size of Japanese ears can be found by referring to the Japanese human body size database (1992-1994) created by the Human Life Engineering Research Center (HQL). If the panel 10 is larger than the average size of Japanese ears, the panel 10 is considered to be large enough to cover the entire foreign ear.

  The mounting member 3 can transmit air conduction sound and vibration sound via 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 a sound having a volume equivalent to that of a conventional dynamic receiver is output, the sound transmitted to the surroundings of the combination 1 due to the vibration of 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 mounting member 3 transmits vibration sound due to the vibration of the panel 10, even if the user wears an earphone or a headphone, for example, the user can contact the earphone or the headphone by bringing the mounting member 3 into contact therewith. Sounds can be heard through headphones and body parts. When the panel 10 of the mounting member 3 is vibrated to output sound, air conduction sound and vibration sound transmitted through a part of the human body are generated from the panel 10. Therefore, in this case, the user can hear the sound output from the mounting member 3 by bringing his / her ear into contact with the panel 10 of the mounting member 3 (as opposed to the speaker 130 of the electronic device 100).

  As described above, the mounting member 3 according to the present embodiment includes the piezoelectric element 30, and the deformation of the piezoelectric element 30 generates air conduction sound and vibration sound transmitted through a part of the human body. Since the attachment member 3 according to this embodiment is electrically connected to the electronic device 100 through the connection terminals 20 and 150, the piezoelectric element 30 can be supplied with electric power from the electronic device 100. The piezoelectric element 30 may be supplied with power from an external power source such as a spare battery for the electronic device 100 built in the panel housing portion 13 of the mounting member 3 instead of from the electronic device 100.

  In addition, as for the combination body 1 which concerns on this embodiment, it is desirable to enable it to switch whether a sound is output from the speaker 130 of the electronic device 100, or a sound is output from the panel 10 of the attachment member 3. FIG. For this reason, it is preferable that at least one of the electronic device 100 and the attachment member 3 includes an attachment detection unit that detects that the attachment member 3 is attached to the electronic device 100. For example, the mounting detection unit is configured such that the electronic device 100 and the mounting member 3 are electrically connected to each other by, for example, the connection terminals 20 and 150 as at least one of the control unit of the electronic device 100 and the control unit provided on the circuit board 50 of the mounting member 3. It can be detected that the connection has been made automatically. Further, the attachment detection unit can be, for example, a switch disposed on at least one of the electronic device 100 and the attachment member 3, and the switch detects that the attachment member 3 is attached to the electronic device 100. You may make it do. In this way, the combination 1 according to the present embodiment is configured so that when the attachment detection unit detects that the attachment member 3 is attached to the electronic device 100, the attachment device 3 outputs sound. It is preferable to control the mounting member 3.

  As described above, when sound is output from the panel 10 of the mounting member 3, unnecessary vibration is generated from other than the panel of the mounting member 3 by controlling so that no sound is output from the speaker 130 of the electronic device 100. To reduce the occurrence of sound leakage. Further, when the sound is output from the panel 10 of the mounting member 3, the power consumption of the combined body 1 as a whole can be reduced by controlling so that no sound is output from the speaker 130 of the electronic device 100.

  When sound is output from the panel 10 of the mounting member 3 based on an audio signal supplied from the electronic device 100, the sound is output from the panel 10 according to various conditions such as the shape and size of the mounting member 3 and the panel 10. It is assumed that the acoustic characteristics of the sound to be changed will change. Therefore, when the electronic device 100 supplies the power of the mounting member 3, when outputting sound from the panel 10, it is desirable for the electronic device 100 to supply a voltage that meets the above various conditions. For this reason, ID information (including information such as the sizes of the panel 10 and the mounting member 3) of the mounting member 3 is stored on the side of the mounting member 3 in, for example, a control unit or a storage unit provided in the circuit board 50. You can keep it. Such ID information can be transmitted to the electronic device 100 via the connection terminals 20 and 150 such as microUSB or an earphone jack. Thereby, when the attachment member 3 is connected to the electronic device 100, the electronic device 100 can determine an output voltage or the like based on the ID information. Or the control part with which the circuit board 50 of the attachment member 3 was equipped based on the audio | voice signal transmitted from the electronic device 100 may determine an output voltage etc. based on ID information of the attachment member 3. FIG.

  Note that the control of the electronic device 100 performs the control of the sound output from the speaker 130 and the panel 10 as described above, the control of transmitting an audio signal to the mounting member 3, and the control of supplying power to the mounting member 3. If it is possible, it is not necessary to provide the circuit board 50 on the attachment member 3. In this case, the circuit board 50 can be omitted from the attachment member 3.

  As described above, in the combined body 1 according to this embodiment, it is preferable that the attachment member 3 is provided with the vibration reducing member 9 at a portion where the electronic device 100 abuts. If the vibration reducing member 9 is arranged in this manner, even if the panel 10 vibrates, the vibration can be reduced from being transmitted to the electronic device 100 side. The occurrence of sound leakage from parts other than 10 is reduced.

  In the attachment member 3 according to the present embodiment, the vibration reducing member 9 can be disposed in the vicinity of the connection terminal 20. In this way, when the piezoelectric element 30 of the mounting member 3 vibrates, the vibration is suppressed from being transmitted to the electronic device 100 via the connection terminals 20 and 150. Therefore, when sound is output from the panel 10 of the mounting member 3, the risk of sound leakage from portions other than the panel 10 in the combination 1 can be reduced. On the other hand, in the attachment member 3 according to the present embodiment, the vibration reducing member 9 may not be disposed in the vicinity of the connection terminal 20. In this case, it is possible to reduce a risk that the connection terminal 20 of the attachment member 3 is detached from the connection terminal 150 of the electronic device 150 due to vibration of the panel 10 due to deformation of the piezoelectric element 30.

  Thus, according to the attachment member 3 according to the present embodiment, the panel 10 is deformed due to the deformation of the piezoelectric element 30 attached to the back surface of the panel 10, and the object in contact with the deformed panel 10 is applied. It conveys air conduction sound and vibration sound to it. Accordingly, since the air conduction sound and the vibration sound can be transmitted to the user without causing the vibration body to protrude from the outer surface of the housing of the electronic device 100 and the mounting member 3, the vibration body is much smaller than the housing. Usability is improved as compared with the electronic device described in Patent Document 1 in which the contact is made with the human body. In addition, since it is not necessary to put the user's ears on the piezoelectric element itself, the piezoelectric element 30 itself is not easily damaged. In addition, when the casing is deformed instead of the panel 10, the user tends to drop the terminal when generating vibration, whereas this is the case when the panel 10 is vibrated. Is hard to get up.

  Further, according to the mounting member 3 according to the present embodiment, even if the electronic device does not include a receiver that originally generates air conduction sound and vibration sound transmitted through a part of the human body, the main body of the electronic device It is possible to generate air conduction sound and vibration sound transmitted through a part of the human body. Therefore, for example, during a voice call, the user listens to the air conduction sound and vibration sound transmitted through a part of the human body from the panel 10, while the electronic device 100 is not during a voice call such as music playback. It can be used properly such as listening to the sound output from the speaker 130.

  In addition, many electronic devices such as smartphones are used in jackets and cases. According to the mounting member 3 according to the present embodiment, it is transmitted through air conduction sound and a part of the human body from other than the main body of the electronic device while maintaining an uncomfortable appearance like a conventional smartphone jacket or case. Vibration sound can be generated.

  The piezoelectric element 30 is bonded to the panel 10 with a bonding member. Thereby, the piezoelectric element 30 can be attached to the panel 10 in a state in which the degree of freedom of deformation of the piezoelectric element 30 is hardly hindered. In this case, the joining member can be a non-heating type curable adhesive. Thereby, there is an advantage that thermal stress shrinkage hardly occurs between the piezoelectric element 30 and the panel 10 at the time of curing. The joining member can be a double-sided tape. Thereby, there is an advantage that contraction stress is hardly applied between the piezoelectric element 30 and the panel 10 as in the case of using an adhesive.

  In addition, the panel 10 is deformed to transmit air conduction sound and vibration sound not only in the attachment region to which the piezoelectric element 30 is attached, but also in any part of the panel 10. For this reason, the user can hear the vibration sound by bringing his / her ear into contact with an arbitrary position of the panel 10 in addition to the air conduction sound through the air.

  Further, a reinforcing member is disposed between the piezoelectric element 30 and the panel 10 to reduce the possibility that the external force is transmitted to the piezoelectric element 30 and the piezoelectric element 30 is damaged, for example, when an external force is applied to the panel 10. You can also Moreover, even if the panel 10 is brought into strong contact with the human body, the vibration of the panel 10 can be hardly attenuated. Further, if a reinforcing member is disposed between the piezoelectric element 30 and the panel 10, the resonance frequency of the panel 10 is lowered and the acoustic characteristics in the low frequency band are improved. Instead of the reinforcing member, a plate-like weight may be attached to the piezoelectric element 30 by a joining member.

  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, the functions included in each member, each step, etc. can be rearranged so that there is no logical contradiction, and a plurality of components, steps, etc. can be combined into one or divided. is there.

  For example, in FIGS. 3 and 4, the mode in which the piezoelectric element 30 is installed above the panel 10 has been described. However, the piezoelectric element 30 may be disposed in the center of the panel 10. When the piezoelectric element 30 is disposed in the center of the panel 10, the vibration of the piezoelectric element 30 is evenly transmitted to the entire panel 10 to improve the quality of the air conduction sound, and the user can listen to various positions of the panel 10. The vibration sound can be recognized even if it is touched. The number of piezoelectric elements 30 to be installed is not limited to one, and a plurality of piezoelectric elements 30 may be mounted.

  In the electronic device 1 described above, the piezoelectric element 30 is attached to the panel 10, but may be attached to a location different from the panel 10. For example, the piezoelectric element 30 may be attached to any part of the panel housing portion 13 of the attachment member 3. According to such a configuration, the user can hear a sound by bringing a part of the body (for example, an ear) into contact with a surface different from the panel 10.

  Further, the panel 10 can constitute a part or all of any of a display panel, an operation panel, a cover panel, and a lid panel for making the rechargeable battery removable. In particular, when the panel 10 is a display panel, the piezoelectric element 30 is disposed outside the display area for the display function. As a result, there is an advantage that the display is hardly disturbed.

  In the electronic apparatus 1 described above, a piezoelectric element is cited as an example of a vibration element, but the present invention is not limited to this. The vibration element may be different from the piezoelectric element as long as it can vibrate the panel 10. The vibration element may be, for example, an electromagnetic vibration element that is mounted on a conventional dynamic speaker and includes a coil and a magnet. The vibration element may be an eccentric motor, for example.
