Referring to fig. 1 and 9, an electronic device 100 according to an embodiment of the invention includes a housing 20, an electronic component, a vibration module 30a, and a piezoelectric element 70. The electronic component includes an output module 10, a receiving module 50 (see fig. 11), an imaging module 60 (see fig. 11), and a structured light projector 80. The electronic device 100 may be a mobile phone, a tablet computer, a notebook computer, an intelligent watch, an intelligent bracelet, a teller machine, and the like, and the embodiment of the invention is described by taking the electronic device 100 as a mobile phone, it is understood that the specific form of the electronic device 100 may be other, and is not limited herein.

Referring to fig. 2 and 5, the output module 10 is a single package structure, and the output module 10 includes a package housing 11, an infrared lamp 12 and a light-transmitting assembly 13.

The packaging shell 11 is used for packaging the infrared lamp 12 and the light-passing assembly 13 at the same time, or the infrared lamp 12 and the light-passing assembly 13 are packaged in the packaging shell 11 at the same time. The package housing 11 includes a package substrate 111, a package sidewall 112, and a package top 113. The package housing 11 may be made of an Electromagnetic Interference (EMI) shielding material to prevent external EMI from affecting the output module 10.

Referring to fig. 5, the package substrate 111 is used for carrying the infrared lamp 12. In manufacturing the output module 10, the infrared lamp 12 may be formed on the chip 14, and then the infrared lamp 12 and the chip 14 may be disposed together on the package substrate 111, and specifically, the chip 14 may be bonded on the package substrate 111. Meanwhile, the package substrate 111 may also be used to connect with other components of the electronic device 100 (e.g., the housing 20 and the motherboard of the electronic device 100), so as to fix the output module 10 in the electronic device 100.

The package sidewall 112 may be disposed around the infrared lamp 12 and the light-passing assembly 13, the package sidewall 112 extends from the package substrate 111, the package sidewall 112 may be combined with the package substrate 111, and preferably, the package sidewall 112 and the package substrate 111 are detachably connected, so as to facilitate maintenance of the infrared lamp 12 and the light-passing assembly 13 after the package sidewall 112 is removed. The package side wall 112 may be made of an infrared opaque material to prevent infrared light emitted by the infrared lamp 12 from passing through the package side wall 112.

The package top 113 is opposite to the package substrate 111, and the package top 113 is connected to the package sidewall 112. The package top 113 is formed with a light exit window 1131, the light exit window 1131 corresponds to the infrared lamp 12, and the infrared light emitted by the infrared lamp 12 passes through the light exit window 1131. The package top 113 and the package side wall 112 may be formed integrally or separately. In one example, the light exit window 1131 is a through hole, and the package top 113 is made of a material opaque to infrared light. In another example, the package top 113 is made of an infrared opaque material and an infrared opaque material, specifically, the light-exiting window 1131 is made of an infrared opaque material, and the rest of the light-exiting window is made of an infrared opaque material, further, the light-exiting window 1131 may be formed with a lens structure to improve the emission angle of infrared light exiting from the light-exiting window 1131, for example, the light-exiting window 1131 is formed with a concave lens structure to diffuse light passing through the light-exiting window 1131 to exit outwards; the light-emitting window 1131 is formed with a convex lens structure, so that light passing through the light-emitting window 1131 is gathered and emitted outwards.

Referring to fig. 5 and 6, the light passing assembly 13 is located on the light emitting path of the infrared lamp 12, and the infrared light emitted by the infrared lamp 12 passes through the light passing assembly 13 and then exits from the light exit window 1131. The light passing member 13 includes a base 131 and a stretchable film 133.

The substrate 131 may be made of a material that is opaque to infrared light and conductive, the substrate 131 may be connected to the package sidewall 112 through a connector 15, and a circuit such as a driving circuit of the light passing assembly 13 may be laid in the connector 15. The matrix 131 may also be embedded in the light exit window 1131. The overall shape of the base 131 may be circular, rectangular, oval, etc. The base body 131 is provided with a light through hole 132, the light through hole 132 penetrates through the base body 131, and infrared light emitted by the infrared lamp 12 penetrates through the light through hole 132 and then penetrates through the light through assembly 13.

The stretchable film 133 is accommodated in the light passing hole 132, specifically, the stretchable film 133 may be fixed in the light passing hole 132, the stretchable film 133 may shield at least a portion of the light emitting area of the light passing hole 132, the infrared light cannot pass through the stretchable film 133 or the stretchable film 133 has a very low transmittance to the infrared light, the stretchable film 133 may be made of a material having an electrostrictive effect, such as polyvinylidene Fluoride (PVDE), and the stretchable film 133 may deform under the action of an electric field, it can be understood that when the stretchable film 133 deforms, the area of the light passing hole 132 shielded by the stretchable film 133 also changes, that is, the area of the light passing hole 132 changes, that is, the light quantity passing through the light passing assembly 13 and the distribution of light change, in one example, by controlling the deformation of the stretchable film 133, the infrared light emitted from the infrared lamp 12 may exit the package housing 11 at different angles of view, and the infrared light may be used for different purposes, for example, when the infrared light emitted from the package housing 11 passes through the package housing 11 at different angles, such as the infrared light emitting angle 90, the infrared light emitting object 90, the infrared light emitting device 20, 10, the infrared light receiving object 90, the infrared light emitting device 90, the infrared light receiving device 90, the infrared light passing through the package housing 90, the infrared object 100, the infrared object receiving device 20, the infrared object 90, the infrared object receiving device 20, the infrared object 90, the infrared object receiving device 20, the infrared object receiving device shown in the infrared object receiving device 20, the infrared object receiving device shown in the infrared object receiving device 5, and the infrared object receiving device shown in the infrared object receiving device 5, the infrared object receiving device shown in the package housing 11, and the first view angle shown in the first view angle of the first embodiment of the present invention as shown in the invention as shown in the invention.

Referring to fig. 6, in particular, the flexible film 133 includes a first surface 1331 and a second surface 1332, the first surface 1331 is combined with the inner wall of the light passing hole 132, and the second surface 1332 is opposite to the first surface 1331. In the embodiment shown in fig. 6, two stretchable films 133 are accommodated in one light passing hole 132, and the two stretchable films 133 may be symmetrically disposed in the light passing hole 132. As shown in fig. 6(a), when no electric field is applied, the stretchable film 133 is in a natural state, a gap 1321 is formed between the two second surfaces 1332, and infrared light can pass through the gap 1321; as shown in fig. 6(b), when an electric field is applied to the stretchable film 133, specifically, the substrate 131 may be connected to the negative electrode of the power source, the stretchable film 133 may be connected to the positive electrode of the power source, or the substrate 131 is connected to the positive electrode of the power source, the stretchable film 133 is connected to the negative electrode of the power source, the stretchable film 133 is deformed by the electric field, the first surface 1331 is coupled to the inner wall of the light-transmitting hole 132 and is hard to move relative to the inner wall, the second surface 1332 has a high degree of freedom, and the second surface 1332 extends and gradually reduces the size of the gap 1321, that is, the area of the stretchable film 133 blocking the light-transmitting hole 132 is increased. By controlling the strength of the electric field, the amount of extension of the second surface 1332 can be controlled to control the light passing area of the light passing hole 132, that is, the size of the gap 1321. In one example, as shown in fig. 6(c), when the two second surfaces 1332 are completely attached to each other, the light passing area of the light passing hole 132 is zero, and infrared light cannot pass through the light passing hole 132. Of course, other numbers of the stretchable films 133 may be disposed in one light-passing hole 132, for example, one, three, four, five, six, etc., and the specific shape of the stretchable film 133 may also be adjusted according to the shape of the light-passing hole 132, etc., without limitation.

In the embodiment shown in fig. 6, the number of the light passing holes 132 formed in the base 131 is one, and the amount of deformation of the stretchable film 133 and thus the size of the gap 1321 are changed by controlling the magnitude of the electric field, so as to change the angle of view of the infrared ray, for example, to the first angle of view or the second angle of view.

In the embodiment shown in fig. 7 and 8, the number of the light passing holes 132 is at least two, and the telescopic film 133 can also change the number of the light passing holes 132 under the action of the electric field. In this embodiment, the plurality of light holes 132 are distributed in a radial array, the light hole 132 located at the center may correspond to the light emitting center of the infrared lamp 12, the remaining light holes 132 are distributed around the light hole 132 at the center, and the flexible films 133 in different light holes 132 may be independently connected to or disconnected from the power supply. When all the telescopic films 133 are not electrified, the light-passing assembly 13 has the highest infrared light passing rate, and the viewing angle is the largest (as shown in fig. 7); when the light transmission amount is required to be reduced or the field angle is required to be reduced, the telescopic film 133 positioned in the light transmission holes 132 at the edge of the array can be controlled to deform and block the corresponding light transmission holes 132 (as shown in fig. 8). Of course, in other embodiments, the distribution of the plurality of light-transmitting holes 132 may be different, and the distribution of the blocked light-transmitting holes 132 may be set according to the user's needs, for example, by controlling the open/close states of the plurality of light-transmitting holes 132, so that the light emitted from the output module 10 takes the shape of an animal, a heart, or the like.

Referring to fig. 1 and 9, the housing 20 may serve as a mounting carrier for the output module 10, or the output module 10 may be disposed in the housing 20. The chassis 20 may be a housing of the electronic device 100.

Referring to fig. 1, 9 and 10, the casing 20 includes a top portion 21 and a bottom portion 22, and the casing 20 is provided with a casing infrared through hole 23 and a casing vibration through hole 2a spaced from each other at a position corresponding to the electronic component. When the output module 10 is arranged in the machine shell 20, the infrared lamp 12 corresponds to the machine shell infrared through hole 23. The infrared lamp 12 and the housing infrared through hole 23 correspond to each other, and the light emitted by the infrared lamp 12 can pass through the housing infrared through hole 23, specifically, the infrared lamp 12 is opposite to the housing infrared through hole 23, or the light emitted by the infrared lamp 12 passes through the housing infrared through hole 23 after being acted by the light guide element.

The vibration module 30a is mounted on the cabinet 20. The vibration module 30a may include a display screen 90 and a cover plate 30, or the display screen 90 and the cover plate 30 are combined to form the vibration module 30a, so as to improve the rigidity of the vibration module 30 a. The display screen 90 is disposed on the housing 20 and forms a receiving cavity 91 with the housing 20, and the cover plate 30 is disposed on the housing 20 and located on a side of the display screen 90 away from the receiving cavity 91 to protect the display screen 90. Since the output module 10 according to the embodiment of the invention can occupy a smaller volume, the volume for disposing the display screen 90 in the housing 20 can be correspondingly increased, so as to increase the screen occupation ratio of the electronic device 100. Specifically, the display screen 90, the output module 10 and the piezoelectric element 70 are disposed between the top portion 21 and the bottom portion 22, and the top portion 21 is located above the bottom portion 22 in a state that the user normally uses the electronic device 100, as shown in fig. 1, the output module 10 may be disposed between the display screen 90 and the top portion 21. In other embodiments, the display screen 90 may be a full screen with a gap, the display screen 90 surrounds the output module 10, and the output module 10 is exposed from the gap of the display screen 90.

The piezoelectric element 70 is made of a ceramic or quartz crystal material, and the piezoelectric element 70 may be a single wafer, a twin wafer, or a laminated piezoelectric element 70. The piezoelectric element 70 is coupled to the vibration module 30a and spaced apart from the output module 10. Specifically, the piezoelectric element 70 is accommodated in the casing vibration through hole 2a, is coupled to the cover plate 30, and is spaced apart from the casing 20, and may be: the piezoelectric element 70 is partially accommodated in the chassis vibration through hole 2a, or the piezoelectric element 70 is entirely accommodated in the chassis vibration through hole 2 a. When an electric signal (voltage) is applied to both ends of the piezoelectric element 70, the piezoelectric element 70 is mechanically deformed, for example, expanded or contracted, due to the inverse piezoelectric effect, thereby causing the vibration module 30a coupled to the piezoelectric element 70 to vibrate according to the frequency of the electric signal. When the user's body is in contact with the vibration module 30a, bone conduction sound is transmitted to the user's auditory nerve through a portion of the user's body in contact with the vibration module 30a (e.g., cartilage of the outer ear, teeth). In this way, the user can realize the functions of voice call, listening to music, etc. through the piezoelectric element 70 and the vibration module 30 a. In an embodiment of the present invention, the processor of the electronic device 100 is configured to acquire a sound signal and apply an electrical signal corresponding to the sound signal to the two ends of the piezoelectric element 70.

It can be understood that the traditional receiver structure adopts air conduction sound, the local sound pressure of the receiver is usually about 90 dB-100 dB when the receiver works, and the sound is still about 50 dB-60 dB even if the sound is transmitted to the range of 1 meter around in the quiet surrounding environment (such as in the general office environment of about 50 dB), which causes the conversation content among the callers to be perceived around, resulting in privacy leakage. The electronic device 100 according to the embodiment of the invention adopts the piezoelectric element 70 and the vibration module 30a to realize bone conduction sound transmission, and the sound of the call is mainly sensed by the bone conduction of the vibration and can effectively ensure the privacy of the call content.

Referring again to fig. 9 and 10, the piezoelectric element 70 and the display screen 90 are attached to the cover plate 30 by the joint 30 b. The bonding member 30b is an adhesive, a double-sided tape, an adhesive tape, or the like having a thermosetting property and an ultraviolet curing property. For example, the joining member 30b may be an optically elastic resin (a colorless and transparent ultraviolet-curing acrylic adhesive). The area of the cover 30 bonded to the piezoelectric element 70 is spaced apart from the area of the cover 30 bonded to the display screen 90 to prevent the display of the display screen 90 from being interfered with by the piezoelectric element 70. Of course, the cover 30 can also be coupled to the housing 20 by the coupling member 30b, so that compared with the case where the cover 30 is directly disposed on the housing 20, the vibration of the vibration module 30a can be prevented from being directly transmitted to the housing 20, thereby reducing the possibility that the user may drop the electronic device 100 due to the excessive vibration amplitude of the housing 20.

The cover plate 30 may be light-transmissive, and the material of the cover plate 30 may be light-transmissive glass, resin, plastic, or the like. The cover plate 30 is disposed on the chassis 20, the cover plate 30 includes an inner surface 32 combined with the chassis 20, and an outer surface 31 opposite to the inner surface 32, and the light emitted from the output module 10 sequentially passes through the inner surface 32 and the outer surface 31 and then passes through the cover plate 30.
