The following describes in detail the technical solutions disclosed in the embodiments of the present application with reference to the accompanying drawings.

As shown in fig. 1-2, an embodiment of the present application discloses an electronic device, which includes a housing 100, a display screen 200, an optical fingerprint module 300, a membrane 400, and a control module.

The housing 100 provides a mounting base for other components in the electronic device while providing protection for those components.

The display screen 200 is disposed on the housing 100, and the display screen 200 and the housing 100 form a device cavity 500, the device cavity 500 being capable of providing installation space for some other components of the electronic device. The optical fingerprint module 300 and the membrane 400 are arranged in the equipment inner cavity 500, so that the optical fingerprint module 300 and the membrane 400 can be well protected by the equipment inner cavity 500, and normal operation of the optical fingerprint module 300 and the membrane 400 is ensured.

The device lumen 500 includes a deformable cavity 510, the deformable cavity 510 not being deformed in the event that the display 200 is not pressed; under the condition that the display screen 200 is pressed, the deformable cavity 510 is deformed, and air in the deformable cavity 510 can drive the diaphragm 400 to vibrate, the control module is connected with the optical fingerprint module 300, and the control module can control the optical fingerprint module 300 to start working. In the case that the diaphragm 400 is driven by the deformable cavity 510, the control module may drive the optical fingerprint module 300 to start, that is, the vibration of the diaphragm 400 may wake up the optical fingerprint module 300, and thus, the electronic device may start, so that the electronic device may start to operate.

According to the electronic device disclosed by the embodiment of the application, the structure of the electronic device in the background technology is improved, so that the device inner cavity 500 comprises the deformable cavity 510, and the deformable cavity 510 is not deformed under the condition that the display screen 200 is not pressed. When the display screen 200 is pressed, the deformable cavity 510 deforms, and at this time, the deformation of the deformable cavity 510 can drive the diaphragm 400 to vibrate, and the vibrating diaphragm 400 can trigger the optical fingerprint module 300. The control module is connected with the optical fingerprint module 300, so that the optical fingerprint module 300 can be started by the control module, and the control module drives the optical fingerprint module 300 under the condition that the membrane 400 is driven by the deformable cavity 510, so that the electronic equipment can be unlocked.

That is, in the electronic device disclosed in the embodiment of the present application, the wake-up mechanism of the electronic device is simpler, and when the user presses the display screen 200 at any time when using the optical fingerprint module 300, the user can wake up the optical fingerprint module 300 and work, so as to solve the problem that the current electronic device has difficulty in waking up the optical fingerprint module.

In an alternative embodiment, the deformable cavity 510 may be an air bag, where the air bag is disposed adjacent to the display screen 200, and when the display screen 200 is pressed, the air bag is pressed, and thus deformed, so as to drive the diaphragm 400 to vibrate.

In the electronic device disclosed in the embodiments of the present application, the electronic device may include an acoustic device 600, where the housing 100 is provided with a communication channel 110, and an inner cavity of the acoustic device 600 is communicated with the deformable cavity 510 through the communication channel 110. As described above, by pressing the display screen 200, the deformable cavity 510 deforms, so that the membrane 400 vibrates, and the optical fingerprint module 300 can be awakened. Alternatively, the acoustic device 600 may include a diaphragm 400, where the diaphragm 400 is disposed in an inner cavity, and where the diaphragm 400 in the inner cavity vibrates when the deformable cavity 510 is deformed, so that the control module drives the optical fingerprint module 300. By the mode, the purpose of multiplexing the membrane 400 can be achieved, and further the effect of one object can be achieved. Of course, the membrane 400 may be a separate part, or may be a part inside other devices, so long as the optical fingerprint module 300 can be awakened by vibration of the membrane 400, which is not particularly limited in the embodiment of the present application.

In a further aspect, the casing 100 may be provided with a sound guiding channel 120, where the sound guiding channel 120 is used to collect sound in the external environment to the acoustic device 600, or transmit sound in the acoustic device 600 to the external environment. The sound guide channel 120 includes a first sound guide section 121, a second sound guide section 122 and a third sound guide section 123, wherein the first sound guide section 121 is communicated with a first end of the second sound guide section 122, and the third sound guide section 123 is communicated with a second end of the second sound guide section 122, that is, the first sound guide section 121, the second sound guide section 122 and the third sound guide section 123 are communicated with each other. In addition, the penetrating direction of the first sound guiding section 121 is intersected with the penetrating direction of the second sound guiding section 122, and the penetrating direction of the second sound guiding section 122 is intersected with the penetrating direction of the third sound guiding section 123, in this case, the sound guiding channel 120 forms a curved channel, so that the electronic device has better waterproof and dustproof capabilities, and dust and water drops in the external environment can be prevented from interfering with the internal components of the electronic device.

In an alternative, the first sound guide section 121 may be parallel to the third sound guide section 123. Such a parallel structure is more advantageous for tool processing when the sound guide 120 is cut.

In another alternative, the outer end of the first sound guiding section 121 is lower than the inner end of the first sound guiding section 121 (i.e., the end of the first sound guiding section 121 closer to the acoustic device 600), so that the foreign matter guiding function is better, and the waterproof and dustproof effects can be better exerted.

There are many kinds of acoustic devices 600, and the acoustic device 600 may be a microphone or a speaker. Alternatively, the acoustic device 600 is a microphone, the membrane 400 may be a MEMS (Microelectro Mechanical Systems, micro-electromechanical system) membrane, the MEMS membrane is sensitive to external vibration, when the display screen 200 is pressed, the deformable cavity 510 deforms, the airflow change in the deformable cavity 510 can be picked up by the MEMS membrane, and the MEMS membrane vibrates, so that the control module drives the optical fingerprint module 300.

In the electronic device disclosed in the embodiment of the present application, the acoustic device 600 may be a speaker, and the speaker includes a speaker housing and a diaphragm 400, where the speaker housing has an inner cavity, and the diaphragm 400 may be disposed in the inner cavity and may partition the inner cavity into a front cavity and a rear cavity. The housing 100 may be provided with a sound guide channel 120, where the sound guide channel 120 is communicated with the front cavity, and the rear cavity may be communicated with the deformable cavity 510 through the communication channel 110, so that the volume of the rear cavity may be increased, and thus the bass performance of the speaker may be enhanced.

In a further technical solution, a valve 111 may be disposed in the communication channel 110, where the valve 111 has a first state and a second state, and when the valve 111 is in the first state, the communication channel 110 is in a closed state, and only the sound guide channel 120 is in communication with the front cavity, and a bass effect may occur when the speaker sounds.

By the method, two bass effects of the loudspeaker can be achieved, and therefore the electronic equipment can achieve more flexible bass performance.

Specifically, the detecting unit is connected with the diaphragm 400, the detecting unit can detect the signal amplitude generated by vibration of the diaphragm 400, the control module controls the optical fingerprint module 300 to start under the condition that the signal amplitude is larger than a preset threshold, and the control module controls the optical fingerprint module 300 to keep closed under the condition that the signal amplitude is smaller than or equal to the preset threshold, so that false triggering of a user can be avoided.

Under normal conditions, the power supply voltage of the acoustic device 600 used in the general electronic equipment can reach 1.5V at the minimum, the power consumption is below 0.1mA, when the detection unit detects that the trigger signal given by the acoustic device 600 is greater than the preset threshold, an interrupt is triggered, a start command is sent to the control module at this time, and the control module controls the optical fingerprint module 300 to start after receiving the start command, and the acoustic device 600 is in a dormant state. Otherwise, when the detection unit detects that the trigger signal given by the acoustic device 600 is smaller than or equal to the preset threshold, the triggering is successful, and the control module controls the optical fingerprint module 300 to be in the off state.
