Referring to fig. 1, 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 (as shown in fig. 7), an imaging module 60 (as shown in fig. 7), and an infrared fill-in light 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 3, the output module 10 is a single package structure, and includes a package housing 11, a structured light projector 12, and a proximity infrared lamp 13.

The package housing 11 is used to package the structured light projector 12 and the proximity infrared lamp 13 at the same time, or the structured light projector 12 and the proximity infrared lamp 13 are packaged in the package housing 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.

The package substrate 111 is used to carry the structural light projector 12 and the proximity infrared lamp 13. In manufacturing the output module 10, the structured light projector 12 and the proximity infrared lamp 13 may be formed on one chip 14, and then the structured light projector 12, the proximity infrared lamp 13, and the chip 14 may be provided together on the package substrate 111, 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 surround the structured light projector 12 and the proximity infrared lamp 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 structured light projector 12 and the proximity infrared lamp 13 after the package sidewall 112 is removed. The package side walls 112 may be made of an infrared opaque material to prevent infrared light emitted by the structured light projector 12 or the proximity infrared lamp 13 from passing through the package side walls 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 structured light window 1131 and a proximity window 1132, the structured light window 1131 corresponds to the structured light projector 12, and structured light (infrared light) emitted by the structured light projector 12 passes through the structured light window 1131; the proximity window 1132 corresponds to the proximity infrared lamp 13, and infrared light emitted from the proximity infrared lamp 13 passes out of the proximity window 1132. The package top 113 and the package side wall 112 may be formed integrally or separately. In one example, the structured light window 1131 and the proximity window 1132 are through holes and the package top 113 is made of an infrared opaque material. In another example, the package top 113 is made of an infrared opaque material and an infrared opaque material, specifically, the structured light window 1131 and the proximity window 1132 are made of an infrared opaque material, and the rest of the package top is made of an infrared opaque material, further, the structured light window 1131 and the proximity window 1132 may be formed with a lens structure to improve the emission angle of infrared light emitted from the structured light window 1131 and the proximity window 1132, for example, the structured light window 1131 is formed with a concave lens structure to make light passing through the structured light window 1131 diverge and emit outwards; the proximity window 1132 is formed with a convex lens structure to focus light passing through the proximity window 1132 to be emitted outward.

The structured light projector 12 and the proximity infrared lamp 13 can be formed on a chip 14, the volume of the structured light projector 12 and the proximity infrared lamp 13 after integration is further reduced, and the manufacturing process is simple. The structured light projector 12 can emit structured light outwards, the structured light can form an infrared laser speckle pattern, the structured light is projected onto the surface of the target object, the structured light pattern modulated by the target object is collected by the infrared camera 62 (as shown in fig. 1), and a depth image of the target object is obtained by analyzing and calculating the modulated structured light pattern (at this time, the structured light projector 12 is used for stereo imaging). In an embodiment of the present invention, the structured light projector 12 includes a light source 121, a frame 122, a lens 123, and a Diffractive Optical Elements (DOEs) 124. The light beam emitted from the light source 121 is collimated or converged by the lens 123, expanded by the diffractive optical element 124, and emitted outward in a certain light beam pattern. In particular, the light source 121 may be formed on the chip 14, and the lens 123 and the diffractive optical element 124 may be fixed to the frame 122, for example by gluing to the frame 122. The proximity infrared lamp 13 may emit infrared light, which passes through the proximity window 1132 and reaches the surface of the object, and the proximity sensor 51 (shown in fig. 7) of the electronic device 100 receives the infrared light reflected by the object to detect the distance of the object to the electronic device 100 (at this time, the proximity infrared lamp 13 is used for infrared ranging).

The structured light projector 12 and the proximity infrared lamp 13 can emit infrared light to the outside of the packaging shell 11 at different powers, specifically, the structured light projector 12 and the proximity infrared lamp 13 can emit infrared light at the same time, and the output module 10 is used for three-dimensional imaging and infrared distance measurement at the same time; or the structured light projector 12 can emit light rays but not emit light rays near the infrared lamp 13, and the output module 10 is only used for stereo imaging; alternatively, the structured light projector 12 may not emit light and emit light near the infrared lamp 13, and the output module 10 is only used for infrared distance measurement. Referring to fig. 4, in the embodiment of the invention, the output module 10 is formed with a ground pin 15, a structured light pin 16 and a proximity light pin 17. A ground pin 15, a structured light pin 16, and a proximity lamp pin 17 may be formed on the package substrate 111, and the structured light projector 12 emits infrared light when the ground pin 15 and the structured light pin 16 are enabled (i.e., when the ground pin 15 and the structured light pin 16 are connected into a circuit and turned on); when the ground pin 15 and the proximity lamp pin 17 are enabled (i.e., when the ground pin 15 and the proximity lamp pin 17 access circuit are on), the proximity infrared lamp 13 emits infrared light; when the ground pin 15, the structured light pin 16, and the proximity lamp pin 17 are enabled (i.e., when the ground pin 15, the structured light pin 16, and the proximity lamp pin 17 access circuit are on), the structured light projector 12 emits infrared light, and the proximity infrared lamp 13 emits infrared light.

Referring to fig. 1 and 6, the housing 20 includes a top portion 21 and a bottom portion 22, and the housing 20 is provided with a housing approaching through hole 23, a housing structure optical through hole 24, and a housing vibration through hole 2a at a position corresponding to the electronic component and the piezoelectric element 70. When the output module 10 is disposed in the housing 20, the proximity infrared lamp 13 corresponds to the housing proximity through hole 23, and the structured light projector 12 corresponds to the housing structured light through hole 24. The light emitted by the near infrared lamp 13 corresponding to the case near through hole 23 can pass through the case near through hole 23, specifically, the near infrared lamp 13 is opposite to the case near through hole 23, or the light emitted by the near infrared lamp 13 passes through the case near through hole 23 after being acted by the light guide element. The structured light projector 12 corresponds to the housing structured light through hole 24, and the description thereof is omitted here. In the embodiment shown in fig. 6, the chassis access opening 23 and the chassis structure optical opening 24 may be spaced apart from each other, although in other embodiments, the chassis access opening 23 and the chassis structure optical opening 24 may be in communication with each other.

Referring to fig. 5 and 6, the vibration module 30a is mounted on the housing 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. 5 and 6, 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. In the embodiment shown in fig. 5, the cover plate 30 covers the chassis structure light through hole 24 and the chassis approach through hole 23, the inner surface 32 of the cover plate 30 is coated with the infrared transmissive ink 40, and the infrared transmissive ink 40 has a high transmittance to infrared light, for example, 85% or more, and a high attenuation to visible light, for example, 70% or more, so that a user can hardly see the area of the electronic device 100 covered by the infrared transmissive ink 40 with naked eyes in normal use. Specifically, infrared-transmissive ink 40 may cover areas of inner surface 32 that do not correspond to display 90.

The infrared transparent ink 40 can further shield at least one of the chassis approach through hole 23, the chassis structure optical through hole 24, and the chassis vibration through hole 2a, that is, the infrared transparent ink 40 can simultaneously shield the chassis approach through hole 23, the chassis structure optical through hole 24, and the chassis vibration through hole 2a (as shown in fig. 6), so that a user can hardly see the internal structure of the electronic device 100 through the chassis approach through hole 23, the chassis structure optical through hole 24, and the chassis vibration through hole 2a, and the electronic device 100 has a more beautiful appearance; the infrared transmitting ink 40 can also cover the chassis approach through hole 23, and does not cover the chassis structure optical through hole 24 and the chassis vibration through hole 2 a; or the infrared transmission ink 40 can cover the chassis structure light through hole 24 and uncover the chassis approach through hole 23 and the chassis vibration through hole 2 a; the infrared transmitting ink 40 can also cover the chassis vibration through hole 2a, and does not cover the chassis approach through hole 23 and the chassis structure light through hole 24; the infrared transmitting ink 40 can also cover the chassis approach through hole 23 and cover the chassis structure light through hole 24, and does not cover the chassis vibration through hole 2 a; the infrared transmitting ink 40 can also cover the chassis structure light through hole 24 and the chassis vibration through hole 2a, and does not cover the chassis approach through hole 23; the ir pass-through ink 40 may also cover the chassis access through hole 23 and the chassis vibration through hole 2a, and uncover the chassis structured light through hole 24.

Referring to fig. 7, the receiving module 50 is integrated with a proximity sensor 51 and a light sensor 52, and the proximity sensor 51 and the light sensor 52 form a single package structure. The infrared light emitted from the proximity infrared lamp 13 is reflected by the external object and then received by the proximity sensor 51, and the proximity sensor 51 determines the distance between the external object and the electronic device 100 according to the received reflected infrared light. The light sensor 52 receives the visible light in the ambient light and detects the intensity of the visible light as a basis for controlling the display brightness of the display 90. The proximity sensor 51 and the optical sensor 52 are packaged together to form the receiving module 50, so that the gap between the two modules during independent assembly is reduced, and the installation space in the electronic device 100 is saved.

Referring to fig. 1 and 7, the imaging module 60 may be one or both of a visible light camera 61 and an infrared camera 62. The imaging module 60 includes a lens mount 63, a lens barrel 64, and an image sensor 65. The lens barrel 64 is mounted on the lens holder 63, and the image sensor 65 is housed in the lens holder 63. The mirror base 63 includes a mounting surface 631, and the mounting surface 631 is located between the lens barrel 64 and the image sensor 65. In the embodiment shown in fig. 7, the receiving module 50 is disposed on the mounting surface 631, and specifically, the receiving module 50 at least partially falls onto the mounting surface 631 in the orthogonal projection of the plane where the mounting surface 631 is located, so that the receiving module 50 and the imaging module 60 are disposed compactly, and the lateral space occupied by the two modules is small.

Referring to fig. 1, the infrared fill-in light 80 is used to emit infrared light, and after the infrared light is reflected by the surface of an external object, the infrared camera 62 of the electronic device 100 receives the infrared light reflected by the object to obtain image information of the object.

In the embodiment shown in fig. 1, the imaging module 60 includes a visible light camera 61 and an infrared light camera 62, and the centers of the output module 10, the visible light camera 61, the infrared light camera 62, the piezoelectric element 70 and the infrared light supplement lamp 80 are located on the same line segment. Specifically, the output module 10, the infrared fill light 80, the piezoelectric element 70, the infrared camera 62, and the visible light camera 61 (as shown in fig. 8) are sequentially arranged from one end to the other end of the line segment; or the output module 10, the visible light camera 61, the piezoelectric element 70, the infrared camera 62 and the infrared fill-in light 80 (as shown in fig. 1) are sequentially arranged from one end of the line segment to the other end; or the infrared camera 62, the infrared light supplement lamp 80, the piezoelectric element 70, the visible light camera 61 and the output module 10 are arranged in sequence from one end of the line segment to the other end; or the infrared camera 62, the visible light camera 61, the piezoelectric element 70, the output module 10 and the infrared light supplement lamp 80 are arranged from one end of the line segment to the other end of the line segment in sequence.
