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 input/output module 10 is a single package structure, and includes a package housing 11, an infrared fill-in light 12, a proximity infrared light 13, and a light sensor 1 d.

The packaging shell 11 is used for packaging the infrared light supplement lamp 12, the proximity infrared lamp 13 and the light sensor 1d at the same time, or the infrared light supplement lamp 12, the proximity infrared lamp 13 and the light sensor 1d 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 input/output module 10. In the present embodiment, the centers of the infrared fill light 12, the proximity infrared light 13, and the light sensor 1d are located on the same line segment, for example: an infrared light supplement lamp 12, a near infrared lamp 13 and a light sensor 1d are sequentially arranged from one end to the other end of the line segment; or, a proximity infrared lamp 13, an infrared light supplement lamp 12 and a light sensor 1d are sequentially arranged from one end to the other end of the line segment; or, the proximity infrared lamp 13, the light sensor 1d and the infrared light supplement lamp 12 are sequentially arranged from one end to the other end of the line segment. In other embodiments, the connection line between the infrared fill light 12, the near infrared light 13 and the light sensor 1d is triangular.

The package substrate 111 is used for carrying the infrared fill light 12, the proximity infrared light 13 and the light sensor 1 d. When the input/output module 10 is manufactured, the infrared fill light 12, the proximity infrared light 13, and the photo sensor 1d may be formed on one chip 14, and then the infrared fill light 12, the proximity infrared light 13, the photo sensor 1d, and the chip 14 are disposed on the package substrate 111 together, 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) to fix the input/output module 10 in the electronic device 100.

The package sidewall 112 may surround the infrared light supplement lamp 12, the proximity infrared lamp 13, and the optical sensor 1d, the package sidewall 112 extends from the package substrate 111, the package sidewall 112 may be combined with the package substrate 111, preferably, the package sidewall 112 is detachably connected to the package substrate 111, so as to repair the infrared light supplement lamp 12, the proximity infrared lamp 13, and the optical sensor 1d after the package sidewall 112 is removed. The package sidewall 112 may be made of a material opaque to infrared light to prevent infrared light emitted from the infrared fill light 12 or the near infrared light 13 from passing through the package sidewall 112.

The package top 113 is opposite to the package substrate 111, and the package top 113 is connected to the package sidewall 112. A light supplement window 1131, a proximity window 1132 and a light sensing window 1133 are formed in the top portion 113 of the package, the light supplement window 1131 corresponds to the infrared light supplement lamp 12, and infrared light emitted by the infrared light supplement lamp 12 passes through the light supplement window 1131; the proximity window 1132 corresponds to the proximity infrared lamp 13, and infrared light emitted by the proximity infrared lamp 13 passes out of the proximity window 1132; the light sensing window 1133 corresponds to the light sensor 1d, and the visible light can pass through the light sensing window 1133 and be incident on the light sensor 1 d. The package top 113 and the package side wall 112 may be formed integrally or separately. In one example, the fill light window 1131, the proximity window 1132, and the light sensing window 1133 are all through holes, and the package top 113 is made of a material opaque to infrared light and visible light. In another example, the package top 113 is made of a material opaque to infrared light, a material transparent to infrared light, a material opaque to visible light, and a material transparent to visible light, and specifically, the fill light window 1131 and the proximity window 1132 are made of a material transparent to infrared light, the light sensing window 1133 is made of a material transparent to visible light, and the rest is made of a material opaque to infrared light and a material opaque to visible light. Further, the fill light window 1131 and the proximity window 1132 may be formed with lens structures to improve the emission angle of the infrared light emitted from the fill light window 1131 and the proximity window 1132, for example, the fill light window 1131 is formed with a concave lens structure to diffuse the light passing through the fill light window 1131 to be emitted outwards; the proximity window 1132 is formed with a convex lens structure, so that light passing through the proximity window 1132 is gathered and emitted outwards; the light sensing window 1133 may also be formed with a lens structure to improve the visible light emitting angle incident from the light sensing window 1133, for example, the light sensing window 1133 has a convex lens structure to gather and project the light incident from the light sensing window 1133 onto the light sensor 1 d.

The infrared light supplement lamp 12, the proximity infrared lamp 13 and the light sensor 1d can be formed on one chip 14, the size of the integrated infrared light supplement lamp 12, the proximity infrared lamp 13 and the light sensor 1d is further reduced, and the preparation process is simple. The infrared fill-in light 12 can emit infrared light, the infrared light passes through the fill-in light window 1131 to project onto the surface of the object, and the infrared camera 62 (as shown in fig. 1) of the electronic device 100 receives the infrared light reflected by the object to obtain image information of the object (at this time, the infrared fill-in light 12 is used for infrared fill-in light). 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 50 (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 light sensor 1d receives visible light in the ambient light incident from the light sensing window 1133, and detects the intensity of the visible light.

The infrared light supplementing lamp 12 and the near infrared lamp 13 can emit infrared light to the outside of the packaging shell 11 at different powers, specifically, the infrared light supplementing lamp 12 and the near infrared lamp 13 can emit infrared light simultaneously, and the input and output module 10 is used for infrared light supplementing and infrared distance measurement simultaneously; the infrared light supplement lamp 12 can emit light rays and does not emit light rays close to the infrared lamp 13, and the input and output module 10 is only used for infrared light supplement; or the infrared light supplement lamp 12 does not emit light and is close to the infrared lamp 13 to emit light, and the input and output module 10 is only used for infrared distance measurement.

Referring to fig. 4, in the embodiment of the invention, the input/output module 10 is formed with a ground pin 15, a fill light pin 16, a proximity light pin 17, and a light sensing pin 1 f. The ground pin 15, the fill-in light pin 16, the proximity light pin 17, and the light sensing pin 1f may be formed on the package substrate 111, and when the ground pin 15 and the fill-in light pin 16 are enabled (i.e., when the ground pin 15 and the fill-in light pin 16 are connected to the circuit), the infrared fill-in light 12 emits infrared light; 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 and the light sensing pin 1f are enabled (i.e., when the ground pin 15 and the light sensing pin 1f are connected to the circuit, the light sensor 1d detects the intensity of the visible light, which is used as a basis for controlling the display brightness of the display screen 90.

Referring to fig. 1 and 5, the housing 20 may serve as a mounting carrier for the input/output module 10, or the input/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, 5 and 6, the casing 20 includes a top portion 21 and a bottom portion 22, and at a position corresponding to the electronic component, the casing 20 is provided with a casing approaching through hole 23, a casing supplementary lighting through hole 24, a casing light sensing through hole 2f and a casing vibration through hole 2a which are spaced from each other. When the input/output module 10 is disposed in the housing 20, the proximity infrared lamp 13 corresponds to the housing proximity through hole 23, the infrared light supplement lamp 12 corresponds to the housing light supplement through hole 24, and the light sensor 1d corresponds to the housing light sense through hole 2 f. 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 infrared light supplement lamp 12 corresponds to the chassis light supplement through hole 24, and the description thereof is omitted. The light sensor 1d and the case light sensing through hole 2f correspond to each other, and the visible light can pass through the case light sensing through hole 2f and be incident on the light sensor 1d, specifically, the light sensor 1d is opposite to the case light sensing through hole 2f, or the incident light of the visible light passes through the case light sensing through hole 2f and is incident on the light sensor 1d after the light guide element acts on the light sensor. In the embodiment shown in fig. 6, the chassis approach through hole 23, the chassis light filling through hole 24 and the chassis light sensing through hole 2f may be spaced from each other, but in other embodiments, the chassis approach through hole 23, the chassis light filling through hole 24 and the chassis light sensing through hole 2f may also be communicated with each other.

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 input/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 90, the input/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 input/output module 10 may be disposed between the display 90 and the top portion 21. In other embodiments, the display 90 may be a full screen with a gap, the display 90 surrounds the input/output module 10, and the input/output module 10 is exposed from the gap of the display 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 input-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.
