The light guide member 13 is movably disposed on the light emission optical path of the infrared lamp 12. Referring to fig. 5 and 6, the output module 10 further includes a driving member 17, and the driving member 17 is used for driving the light guiding element 13 to move so as to be movably disposed on the light emitting path of the infrared lamp 12. Wherein, the driving member 17 drives the light guide element 13 to move so as to be movably arranged on the light emitting optical path of the infrared lamp 12 comprises: in a normal state, the light guide element 13 is arranged on a light emitting optical path of the infrared lamp 12, the infrared lamp 12 is used as an infrared fill lamp (or a near infrared lamp), and when the infrared lamp 12 is used as a near infrared lamp (or an infrared fill lamp), the driving element 17 drives the light guide element 13 to move to leave the light emitting optical path of the infrared lamp 12; or in a normal state, the light guide element 13 is not disposed on the light emitting optical path of the infrared lamp 12, the infrared lamp 12 is used as a proximity infrared lamp (or an infrared fill-in lamp), and when the infrared lamp 12 is used as the infrared fill-in lamp (or a proximity infrared lamp), the driving member 17 drives the light guide element 13 to move to the light emitting optical path of the infrared lamp 12.

Referring to fig. 5, the driving member 17 includes a linear motor, the linear motor includes a stator 172 and a mover 174, the stator 172 is mounted on the package sidewall 112, the mover 174 is connected to the light guiding element 13, and the driving member 17 drives the mover 174 to move so as to drive the light guiding element 13 to move.

In an embodiment of the present invention, the output module 10 may further include a supporting plate (not shown) having a supporting hole, the light guide element 13 is installed in the supporting hole, and the driving element 17 is used for driving the supporting plate to move so as to drive the light guide element 13 to move.

Referring to fig. 3, when the light guide element 13 is located on the light emitting path of the infrared lamp 12, the infrared light emitted by the infrared lamp 12 passes through the light guide element 13, and exits from the package housing 11 as a proximity infrared lamp at a first viewing angle under the action of the light guide element 13; when the light guide element 13 leaves the light emission optical path of the infrared lamp 12, the infrared light emitted from the infrared lamp 12 exits the package housing 11 as an infrared fill-in lamp at a second angle of view, and at this time, the first angle of view is smaller than the second angle of view, where the first angle of view is in a range of 10 degrees to 30 degrees, for example, 10 degrees, 15 degrees, 20 degrees, 25 degrees, or 30 degrees, and the second angle of view is in a range of 60 degrees to 90 degrees, for example, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees, 82 degrees, 85 degrees, 87 degrees, or 90 degrees. The light guide element 13 is used for converging light, and the light guide element 13 includes a convex lens or a lens group with positive focal power, and the lens group can be one or more lenses. In the embodiment of the present invention, the angle of field refers to a range covered by the infrared light exiting from the package case 11 through the light emission window 1131.

Referring to fig. 4, when the light guide element 13 is located on the light emitting path of the infrared lamp 12, the infrared light emitted by the infrared lamp 12 passes through the light guide element 13, and exits from the package housing 11 at a first field angle under the action of the light guide element 13 to serve as an infrared fill-in light; when the light guide member 13 is separated from the light emission optical path of the infrared lamp 12, the infrared light emitted from the infrared lamp 12 is emitted from the package housing 11 as a proximity infrared lamp at a second angle of view, and at this time, the first angle of view is larger than the second angle of view, where the first angle of view is in a range of 60 degrees to 90 degrees, for example, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees, 82 degrees, 85 degrees, 87 degrees, or 90 degrees, and the second angle of view is in a range of 10 degrees to 30 degrees, for example, the second angle of view is 10 degrees, 15 degrees, 20 degrees, 25 degrees, or 30 degrees, and the like. The light guide element 13 is used for diverging light, and the light guide element 13 includes a concave lens or a lens group with negative power, and the lens group can be one or more lenses. In the embodiment of the present invention, the angle of field refers to a range covered by the infrared light exiting from the package case 11 through the light emission window 1131.

When the infrared lamp 12 is turned on and used as an infrared fill-in lamp to emit infrared light to the outside of the package housing 11, the infrared light passes through the light-emitting window 1131 to be projected onto the surface of the object, and the infrared camera 62 (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 lamp 12 is used for infrared fill-in). When the infrared lamp 12 is turned on and used as a proximity infrared lamp to emit infrared light to the outside of the package housing 11, infrared light passes through the light emitting window 1131 and reaches the surface of the object, and the proximity sensor 51 (shown in fig. 9) of the electronic device 100 receives the infrared light reflected by the object to detect the distance from the object to the electronic device 100 (at this time, the infrared lamp 12 is used for infrared ranging).

The infrared lamp 12 can emit infrared light to the outside of the package case 11 at different powers when used as an infrared fill light and when used as a near infrared lamp. Specifically, the infrared lamp 12 emits infrared light to the outside of the package housing 11 at a first power when serving as a proximity infrared lamp, and the infrared lamp 12 emits infrared light to the outside of the package housing 11 at a second power when serving as an infrared fill light, where the first power may be smaller than the second power.

Referring to fig. 1 and 7, 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, 7 and 8, 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 infrared through hole 23 and a casing vibration through hole 2a spaced from each other. 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, that is, 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 light emitted by the infrared lamp 12 passes through the housing infrared through hole 23 after being acted by the light guide element 13.

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. 7 and 8, 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. 8, the cover plate 30 covers the infrared through hole 23 of the chassis, 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 it is difficult for a user to see the area of the electronic device 100 covered by the infrared transmissive ink 40 with naked eyes in normal use.
