Fig. 1 is a schematic top view of an electronic device 1 according to an embodiment of the disclosure. Fig. 2 is a schematic cross-sectional view along the line I-I' in fig. 1. Referring to fig. 1 and 2, the electronic device 1 includes a display panel 10, a passivation layer 11, and a speaker element 12. In some embodiments, the display panel 10 may be replaced with other electronic components, a circuit board, a substrate with electronic components, or a combination thereof, as examples of other electronic devices, but is not limited thereto.
The display panel 10 may provide a display screen. For example, the display panel 10 may include a Liquid Crystal (LC), an organic light-emitting diode (OLED), a Quantum Dot (QD), a fluorescent (fluorescent) material, a phosphorescent (phosphor) material, a light-emitting diode (LED), such as a micro light-emitting diode (emitting diode or mini light-emitting diode), a quantum dot light-emitting diode (QDLED), other materials, or a combination thereof, but not limited thereto.
In an embodiment, the electronic device 1 may further include a Backlight module (not shown), and the display panel 10 may be disposed between the protective layer and the Backlight module. The backlight module may include a light source. The light source may include, but is not limited to, a light-emitting diode (LED), an organic light-emitting diode (organic light emitting diode, OLED), a sub-millimeter light-emitting diode (mini LED), a micro light-emitting diode (micro LED), or a quantum dot LED (may include QLED, QDLED).

For example, the material of the protective layer 11 may include glass, polymer, insulating material, other suitable materials, or a combination of at least two of the above materials. In one embodiment, the passivation layer 11 and the display panel 10 may have the same or different thicknesses.
The speaker element 12 and the display panel 10 may be located below the protection layer 11, and the speaker element 12 contacts the protection layer 11. As shown in fig. 1, the display panel 10 and the speaker element 12 may contact the inner surface S11 of the protective layer 11. In addition, at least part of the speaker element 12 may be located at a side of the display panel 10, and an air gap G may be provided between the speaker element 12 and the display panel 10. In other words, the speaker element 12 may be kept at a distance from the display panel 10 such that a gap exists between the speaker element 12 and the display panel 10. However, the relative arrangement between the display panel 10 and the speaker device 12 may be changed according to the requirement, and is not limited thereto.
In one embodiment, as shown in fig. 2, the speaker element 12 may include a piezoelectric component 120 and a connecting component 121. The connection member 121 may be connected between the piezoelectric member 120 and the protective layer 11. In an embodiment, as shown in fig. 2, the connection part 121 may be located at a side of the display panel 10, and an air gap G may be provided between the connection part 121 and the side of the display panel 10. The display panel 10 may be located between the piezoelectric member 120 and the protective layer 11. Also, the piezoelectric member 120 may partially overlap or entirely overlap the display panel 10. In one embodiment, as shown in fig. 2, a distance D may be maintained between the piezoelectric member 120 and the display panel 10. In other words, there may be no contact between the piezoelectric member 120 and the display panel 10. The distance D may be the maximum distance between the piezoelectric member 120 and the display panel 10 in the thickness direction X of the electronic device 1. The distance D is, for example, in the range of 0.1 millimeter (mm) to 5 centimeters (cm), i.e., 0.1mm +.5 cm, but not limited thereto.
In one embodiment, as shown in fig. 2, the piezoelectric component 120 may include a piezoelectric portion (e.g., the piezoelectric portion 1200 and the piezoelectric portion 1201) and a conductive portion 1202. The piezoelectric portion 1200, the piezoelectric portion 1201, and the conductive portion 1202 overlap each other, and the piezoelectric portion 1200 and the piezoelectric portion 1201 may be located on opposite sides of the conductive portion 1202, respectively, for example. In another embodiment, the piezoelectric portion 1200 and the piezoelectric portion 1201 may be integrated, but is not limited thereto. The material of the piezoelectric portion 1200 and/or the piezoelectric portion 1201 may include lead zirconate titanate (PZT), polyvinylidenefluoride (PVDF), other suitable piezoelectric materials, or a combination of at least two of the foregoing. The material of the conductive portion 1202 may include silver, copper, gold, aluminum, nickel, lead, tin, iron, alloys of the foregoing metals, and/or combinations of at least two of the foregoing materials. In some embodiments, the material of the conductive portion 1202 may be replaced with other suitable rigid materials. The material of the connection part 121 may include a conductive material or other suitable material. The conductive material may be selected from the materials of the conductive portion 1202, but is not limited thereto. In an embodiment, the connecting member 121 and the conductive portion 1202 may be formed of the same material, but not limited thereto. In an embodiment, the conductive portion 1202 may be formed by a portion of the connecting member 121 overlapping the display panel 10, but is not limited thereto. In an embodiment, the material of the connection part 121 may be replaced with a buffer material. It should be noted that the number of the elements and the relative arrangement of the elements in the piezoelectric component 120 may be changed according to requirements, and is not limited to the illustration of fig. 2. For example, the number of piezoelectric parts in the piezoelectric member 120 may be one or more than two, but is not limited thereto.
The speaker element 12 may be connected to the protective layer 11 through a connection part 121. The conductive portion 1202 in the piezoelectric member 120 supplies electric power to the piezoelectric portions (e.g., the piezoelectric portion 1200 and the piezoelectric portion 1201), and the piezoelectric portion converts the electric power into mechanical energy (vibration wave) and transmits the vibration wave to the protective layer 11. In an embodiment, the vibration frequency of the piezoelectric portion may be in the range of 20Hz to 20kHz (20 hz+.the vibration frequency+.20khz), such as 250Hz, 400Hz, 500Hz, 800Hz, 1000Hz, or 2000Hz, but not limited thereto. In other embodiments, the vibration frequency may be in the ultrasonic band.
By setting the speaker 12, the electronic device 1 may not need to set a sound hole in the display region R, so as to increase the screen ratio or realize full-screen display. In an embodiment, the speaker 12 may also provide haptic feedback (e.g., vibration may occur when the electronic device 1 is pressed for a long time), but is not limited thereto.
The arrangement, the shape and the area of the piezoelectric portion (e.g., the piezoelectric portion 1200 or the piezoelectric portion 1201) in the speaker device 12 may be designed according to the requirements (e.g., tone, vibration, etc.). The top view shape refers to a shape viewed in the thickness direction X of the electronic device 1.
For example, as shown in fig. 1, the piezoelectric portion (e.g., the piezoelectric portion 1200 or the piezoelectric portion 1201) may have at least one opening O. The width W1 of the opening O may be greater than the width W2 of the opening O, but is not limited thereto. The width W1 may be a maximum width of the opening O away from the connection part 121, but is not limited thereto. The width W2 may be a minimum width of the opening O adjacent to the connection part 121, but is not limited thereto. The plurality of angles (e.g., angle θ1, angle θ2, angle θ3, and angle θ4) between the sides (e.g., first side E1, second side E2, third side E3, fourth side E4, and fifth side E5) of the piezoelectric portion adjacent to the at least one opening O may be in a range of 95 degrees to 135 degrees, such as 100 degrees, 105 degrees, 110 degrees, or 120 degrees, respectively, i.e., 95 ° - θ1-135 °, 95 ° - θ2-135 °, 95 ° - θ3-135 ° and 95 ° - θ4-135 °. The angles θ1 through θ4 may all be the same, at least partially the same (at least partially different), or all different. In addition, any included angle may be a rounded angle instead of a sharp angle, but is not limited thereto.
By properly designing the position, size and/or shape of the opening, the piezoelectric portion can be made to efficiently conduct vibration waves to the protective layer 11 at low frequency (e.g., 250Hz to 650 Hz) vibration.
In fig. 1, an opening O of a piezoelectric portion (e.g., the piezoelectric portion 1200 or the piezoelectric portion 1201) may face a central region of the electronic device 1. The stability of the piezoelectric member 120 can be increased by connecting the connecting member 121 at a position with a larger width of the piezoelectric portion (e.g., the sixth side E6 of the piezoelectric portion), but the arrangement of the piezoelectric portion (e.g., the piezoelectric portion 1200 or the piezoelectric portion 1201) is not limited thereto. In an embodiment, the piezoelectric portion may be disposed 180 degrees (or at any angle) such that the opening O faces the outside of the electronic device 1. In an embodiment, the piezoelectric portion may have a plurality of openings O. In an embodiment, the piezoelectric portion may not have the opening O. In an embodiment, the top view shape of the piezoelectric portion may include, but is not limited to, a rectangle, triangle, circle, polygon, other suitable shape, or a combination thereof.
The electronic device 1 may further comprise other elements and/or film layers according to different requirements. For example, the electronic device 1 may further include a touch layer (not shown). The touch layer may include, but is not limited to, an out-cell touch (out-cell touch) structure, an in-cell touch (on-cell touch or in-cell touch) structure, or a hybrid touch (hybrid touch) structure. The touch structure may include a two-dimensional (2D) touch structure or a three-dimensional (3D) touch structure.
In the present embodiment, the electronic device 1 may further include a speaker element 13 in addition to the speaker element 12. For example, the speaker 12 may be used as an earpiece, and the speaker 13 may be used as a speaker, but is not limited thereto. Fig. 3 is a schematic cross-sectional view along the line II-II' in fig. 1. Referring to fig. 3, in an embodiment, the speaker element 13 may be disposed on the back surface S10 of the display panel 10, and the speaker element 13 may include a piezoelectric component 130 and a connection component 131. The connection member 131 may be connected between the piezoelectric member 130 and the display panel 10. The connection member 131 may contact the rear surface S10 of the display panel 10, and the piezoelectric member 130 may have a cavity GA between the display panel 10 and the piezoelectric member. In other words, there may be no contact between the piezoelectric member 130 and the display panel 10.
In one embodiment, as shown in fig. 3, the piezoelectric component 130 may include a piezoelectric portion (e.g., the piezoelectric portion 1300 and the piezoelectric portion 1301) and a conductive portion 1302. The piezoelectric portion 1300, the piezoelectric portion 1301, and the conductive portion 1302 may overlap each other. In the present disclosure, "overlapping" includes "complete overlapping" and "partial overlapping" unless specifically stated otherwise. The piezoelectric portion 1300 may be located on opposite sides of the conductive portion 1302, respectively, from the piezoelectric portion 1301, for example. The materials of the piezoelectric portion and the conductive portion are referred to above and will not be repeated here. In addition, the number of piezoelectric parts in the piezoelectric member 130 and the relative arrangement between the piezoelectric parts and the conductive parts 1302 may be changed according to requirements, and are not limited to those shown in fig. 3. For example, the number of piezoelectric portions in the piezoelectric member 130 may be one or more than two. In one embodiment, the material of the connection member 131 may include a buffer material. The cushioning material may include, but is not limited to, a porous material, a soft material, other suitable materials, or a combination of at least two of the foregoing. For example, the cushioning material may comprise silica gel, latex, styrofoam, other suitable materials, or combinations thereof.
The speaker element 13 may be connected to the display panel 10 through a connection part 131. For example, the connection member 131 may contact a backlight module in the electronic device 1, but is not limited thereto. The conductive portion 1302 may provide electrical energy to the piezoelectric portion (e.g., the piezoelectric portion 1300 and the piezoelectric portion 1301), and the piezoelectric portion may convert the electrical energy into mechanical energy (vibration wave) and conduct the vibration wave to the display panel 10 and/or the protective layer 11.
In fig. 1, the piezoelectric portion (e.g., the piezoelectric portion 1300 or the piezoelectric portion 1301) has a rectangular top view, but is not limited thereto. In an embodiment, the top view shape of the piezoelectric portion may include, but is not limited to, a rectangle, a triangle, a circle, a polygon, other suitable shapes, or a combination thereof. In some embodiments, the electronic device 1 may further include a cover 15 (please refer to fig. 3), and a larger cavity may be formed between the cover 15 and the protective layer 11 (or between the cover 15 and the display panel 10), so as to facilitate the piezoelectric portion to effectively conduct the vibration wave to the display panel 10 and the protective layer 11 when vibrating at a low frequency (e.g. 250Hz to 650 Hz). In an embodiment, the electronic device 1 may not comprise the speaker element 13.
Fig. 4A to 4C are schematic top views of various speaker elements applicable to an electronic device (e.g., the electronic device 1 of fig. 1) of the present disclosure, respectively. For example, the speaker element 12 and/or the speaker element 13 in fig. 1 may be replaced by any one or more of the speaker elements 12X to 12Z in fig. 4A to 4C, but is not limited thereto.
In fig. 4A, the main difference between the speaker element 12X and the speaker element 12 in fig. 1 is that the piezoelectric portion (e.g., the piezoelectric portion 1200X or the piezoelectric portion 1201X) of the speaker element 12X has an opening OX in addition to the opening O. The width W1 of the opening O may be greater than the width W2 of the opening O, but is not limited thereto. The width W3 of the opening OX may be greater than the width W4 of the opening OX, but is not limited thereto. The width W1 of the opening O and the width W3 of the opening OX may be the maximum widths of the opening O and the opening OX adjacent to the edge of the piezoelectric portion, respectively, but are not limited thereto. The width W2 of the opening O and the width W4 of the opening OX may be the minimum width of the central region of the opening O and the opening OX, respectively, adjacent to the piezoelectric portion, but are not limited thereto. Width W1 and width W3 may be the same or different, and width W2 and width W4 may be the same or different. The plurality of included angles (e.g., included angles θ1 to θ8) between the piezoelectric portion adjacent to the opening O and the plurality of sides of the opening OX (e.g., the first side E1, the second side E2, the third side E3, the fourth side E4, the fifth side E5, the seventh side E7, the eighth side E8, the ninth side E9, the tenth side E10 and the tenth side E11) may be in a range of 95 degrees to 135 degrees, such as 105 degrees, 110 degrees, 115 degrees, or 120 degrees, i.e., 95 degrees+.θ1 (or θ2, θ3, θ4, θ5, θ6, θ7, θ8) +.135 degrees, respectively. The angles θ1 through θ8 may all be the same, at least partially the same (at least partially different), or all different. In addition, any included angle may be a rounded angle instead of a sharp angle, but is not limited thereto.
In fig. 4B, the main difference between the speaker element 12Y and the speaker element 12 in fig. 1 is that the piezoelectric portion (e.g., the piezoelectric portion 1200Y or the piezoelectric portion 1201Y) of the speaker element 12Y has a neck pillow shape in an upper view, and the piezoelectric portion has a U-like opening OY. However, the detailed structure of the speaker device 12Y and the shape of the opening OY can be changed according to the requirement, but not limited thereto.
In fig. 4C, the main difference between the speaker element 12Z and the speaker element 12 in fig. 1 is that the piezoelectric portion (e.g., the piezoelectric portion 1200Z or the piezoelectric portion 1201Z) of the speaker element 12Z is substantially circular in top view shape, and the piezoelectric portion may not have an opening. In other embodiments, the piezoelectric portion of the speaker element 12Z may comprise at least one arc in top view.
In other embodiments, by properly sizing, shaping, and/or positioning the opening of the piezoelectric portion, the piezoelectric portion can be made to efficiently conduct vibration waves onto the protective layer when vibrating at different frequencies. Accordingly, fig. 1 and 4A to 4C are merely examples of the embodiment of the piezoelectric portion, but the embodiment of the piezoelectric portion is not represented as being limited thereto.
Fig. 5 to 12 are schematic cross-sectional views of electronic devices 1A to 1H according to other embodiments of the present disclosure, respectively. Referring to fig. 5, the main differences between the electronic device 1A and the electronic device 1 in fig. 2 are as follows. In the electronic device 1A, the speaker element 12A may contact the side surface S11S of the protective layer 11 and the side surface S10S of the display panel 10. Further, the speaker element 12A may include the piezoelectric member 120 and the connection member 121A described above. The connection part 121A may contact the side S11S of the protective layer 11 and/or the side S10S of the display panel 10. That is, the connection member 121A may be fixed using the side surface S11S of the protective layer 11 and the side surface S10S of the display panel 10. In some embodiments, the connection part 121A may contact the side S10S of the display panel 10 without contacting the side S11S of the protective layer 11, for example, the connection part 121A may be disposed on the inner surface S11, but is not limited thereto.
By the design that the speaker element 12A contacts the side surface S11S of the protective layer 11 and/or the side surface S10S of the display panel 10, the space in which the speaker element 12A is disposed can be reduced, contributing to realization of a narrow frame. In an embodiment, as shown in fig. 5, the connection part 121A may further include a contact 1210 contacting the back surface S10 of the display panel 10 to increase the contact area between the connection part 121A and the display panel 10. In an embodiment, the electronic device 1A may omit the protection layer 11.
