Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
For the convenience of understanding of the embodiments of the present invention, the following description will be further explained with reference to specific embodiments, which are not to be construed as limiting the embodiments of the present invention.
Before introducing the electronic device corresponding to the embodiment of the present invention, a situation that the electronic device is applicable, that is, the electronic device cannot be used due to excessive signals reflected by the display screen caused by external reasons or mounting components, will be described first. For example, when the mobile phone is dropped to deform the structure, it usually involves a structural change of the display, for example, the display is recessed. Or the assembly parts are inconsistent, and the tolerance is large when the mobile phone production line is assembled. These conditions can cause the influence of excessive noise on the bottom of the mobile phone, such as the function of preventing the mobile phone from being touched by mistake, or the function of screen-off when the mobile phone is close to the ear.
In order to better describe the technical solution of the embodiment of the present invention, a simple schematic structure diagram of a normal mobile phone is first described, only the components related to the present invention are briefly described in this figure, and no specific description is made on other components in the mobile phone. See in particular fig. 1 and 2. Fig. 1 is a sectional view of the inside of the mobile phone, and fig. 2 is a schematic top view of the mobile phone. In fig. 1 and 2, the touch screen TP, the silicone Rubber sleeve Rubber of the signal receiving/transmitting device, the signal transmitting device (for example, the infrared light emitter IR-LED in fig. 1 or fig. 2) and the signal receiving device (the distance Sensor in fig. 1 or fig. 2) are included. After the signal transmitting device transmits the optical signal, the optical signal is refracted by the display screen (the touch screen in fig. 1 or fig. 2) and then received by the signal receiving device. The main function is to detect that the ear is close to a certain distance when a call is made, and the screen is black to save the electric quantity and prevent the false triggering judgment. The specific implementation principle is the prior art and is not explained in more detail here.
When a space formed by the device and the structure is physically changed, for example, the transmittance edge of the touch screen or a diffusion film adhered on the screen is small (the reflection is increased), Rubber around the device is deformed or displaced, the mobile phone is dropped to cause inner micro-deformation, and the like, so that the structure is deformed, for example, as shown in fig. 3, after the display screen of the mobile phone is recessed, the functions of screen blacking, false touch prevention and the like are disabled as shown in fig. 3.
Therefore, the solution provided by the embodiment of the present invention is needed to solve the above technical problem. Specifically, referring to fig. 4, fig. 4 is a schematic structural diagram of an electronic device according to an embodiment of the present invention, and a mobile phone is also taken as an example for description. The electronic device may include other conventional components in the electronic device besides the signal transmitting device 410, the signal receiving device 420, the signal converting device 430, the rotating device 450, and the processor 460, which are described in the embodiment. Since the present embodiment focuses on the relationship among the signal transmitting device 410, the signal receiving device 420, the signal converting device 430, the rotating device 440 and the processor 450, and the functions of the components, so as to avoid the technical problems in the background art as much as possible. Other conventional components included in the electronic device and their functions will not be described here.
The above-mentioned components and their functions are explained in detail, see in particular the following:
a signal transmitting means 410 for transmitting a signal;
a signal receiving device 420, configured to receive a reflected signal after the transmission signal is reflected;
the signal conversion device 430 is configured to perform signal conversion on the reflected signal and input the converted signal to the processor 450;
the processor 450 is configured to control the rotating device 440 to rotate to drive the signal transmitting device 410 to adjust the transmitting angle and/or drive the signal receiving device 420 to adjust the receiving angle when it is determined that the value of the converted signal exceeds the preset threshold.
Specifically, the signal emitting device 410 may be an infrared light emitter as described above, or may be other signal emitters, and emits the completed signal. The specific details may be set according to actual conditions, and are not limited herein.
However, when the display screen or other parts of the electronic device are deformed, the reflection of the transmitted signal is increased, i.e., the reflected signal is increased. For example, in fig. 4, after the display screen is deformed, the reflected signal increases. After the signal conversion device 430 performs signal conversion on the reflected signal, the value of the converted signal will be increased, that is, the optical signal is subjected to signal conversion, and the value of the generated electrical signal will be increased.
Alternatively, for example, the signal conversion device 430 is an optical-to-electrical converter, the emission signal is an optical signal, and the reflected optical signal is converted into an electrical signal by the optical-to-electrical converter and input to the processor 450. The processor 450 can determine whether the value of the electrical signal is greater than a preset threshold, where the first threshold is used to represent an upper limit value of the electrical signal, that is, an upper limit value of the reflected signal received by the signal receiving device 420. Once the received reflection signal exceeds the upper limit value, the normal use of the electronic device is affected, for example, the mobile phone loses the false triggering prevention function, the screen-off function when the mobile phone receives the call, and the like.
Therefore, when the processor 450 detects that the value of the converted signal exceeds the predetermined threshold, the rotating device 440 is controlled to rotate, so that the rotating device 440 rotates to drive the transmitting device to adjust the transmitting angle and/or drive the signal receiving device 420 to adjust the receiving angle.
Whether the transmission angle or the receiving angle is adjusted, the final purpose is to ensure that the reflected signal received by the signal receiving device 420 is below the upper limit value thereof, so as to ensure that the background noise influence received by the mobile phone is within a normal range and does not influence the normal functional use of the electronic equipment as much as possible.
After adjusting the transmission angle and/or the reception angle, the result after the adjustment can be further verified. That is, the electronic device may further include a noise floor detection device 460, configured to detect a noise floor value of the electronic device after the transmission angle and/or the reception angle are adjusted in real time;
the processor 450 is further configured to control the rotating device 440 to stop rotating when it is determined that the currently detected noise floor value is within the preset range.
Specifically, after the processor 450 controls the rotation device 440 to rotate, so as to adjust the transmission angle of the signal transmitting device 410, and/or adjust the receiving angle of the signal receiving device 420, the bottom noise value of the electronic device can be detected by the bottom noise detecting device 460. And further verifying whether the background noise value is within a preset range, wherein if the background noise value is within the preset range, the function of the electronic equipment can be completely ensured to be within a normal working range. Then, the processor 450 controls the rotating device 440 to stop rotating, thereby stopping the signal sending device from adjusting the transmission angle, and/or stopping the signal receiving device 420 from adjusting the receiving angle.
Optionally, in order to minimize the noise floor, that is, to optimize the function of the electronic device, in another executable scheme, after the noise floor detecting device 460 performs the above operations, the processor 450 may be further configured to, when it is determined that the currently detected noise floor is within the preset range, continue to control the rotating device 440 to rotate, so as to drive the signal transmitting device 410 to adjust the transmitting angle, and/or drive the signal receiving device 420 to adjust the receiving angle;
the bottom noise detecting device 460 is further configured to detect a bottom noise value after each angle of transmission and/or reception is adjusted after the rotating device 440 continues to rotate, and transmit the bottom noise value to the processor 450;
the processor 450 is further configured to compare the noise floor values obtained after each adjustment of the transmission angle and/or the reception angle to obtain a minimum noise floor value.
Further optionally, determining the minimum noise floor value may be implemented as follows:
the processor 450 is specifically configured to compare the currently acquired background noise value with a background noise value acquired last time, and use the smaller one of the two as a current reference background noise value;
controlling the rotating device 440 to rotate and obtaining a next background noise value after adjusting the transmitting angle and/or the receiving angle;
and comparing the size between the next acquired base noise value and the current reference base noise value, and taking the minimum base noise value of the two as a new reference base noise value until the transmission angle and/or the receiving angle are adjusted to accord with the preset conditions, and taking the finally acquired reference base noise value as the minimum base noise value.
Specifically, the principle is similar to a bubble method, after a bottom noise value is obtained for the first time, the obtained bottom noise value is used as a reference bottom noise value, after the bottom noise value is detected for the next time, the obtained bottom noise value for the next time is compared with the current reference bottom noise value, if the obtained bottom noise value is larger than the current reference bottom noise value, the current reference bottom noise value is still used as the reference bottom noise value for the next time and is compared with the bottom noise value obtained for the third time, and if the obtained bottom noise value for the third time is smaller than or equal to the current reference bottom noise value, the obtained bottom noise value for the third time is used as a new reference bottom noise value and is compared with the bottom noise value obtained for the fourth time. And repeatedly executing the operation until the transmitting angle and/or the receiving angle are adjusted to meet the preset condition, and taking the finally obtained reference background noise value as the minimum background noise value. Specifically, the preset condition may be a preset number of times, that is, the angle is adjusted to reach the preset number of times. Still alternatively, the preset condition may be a preset angle. That is, the adjustment angle is stopped when it reaches a predetermined angle (e.g., the rotating device 440 rotates the signal transmitting device 410 and/or the signal receiving device 420 one turn).
Further optionally, the signal transmitting device 410 corresponds to at least one rotating device 440, so as to drive the signal transmitting device 410 to adjust the angle. The signal receiving device 420 corresponds to at least one rotating device 440 for driving the signal receiving device 420 to adjust the angle.
In a specific application, only the transmitting angle of the signal transmitting apparatus 410 may be adjusted, and/or only the receiving angle of the signal receiving apparatus 420 may be adjusted. Referring specifically to fig. 5, fig. 5 is a schematic diagram illustrating adjustment of the receiving angle of the signal receiving device 420.
According to the electronic device provided by the embodiment of the invention, the signal is transmitted through the signal transmitting device, and the reflected signal after reflection is received by the signal receiving device. When the reflection signal is too large due to external reasons or assembly reasons, the reflection signal is converted through the signal conversion device, and then the processor can perform accurate identification. Once the value of the converted signal is identified to exceed the preset threshold, the rotating device may be utilized to rotate to drive one of the signal transmitting device and/or the signal receiving device to adjust the transmitting (receiving) angle. To reduce the transmitted (received) signal. And detecting the background noise value through a background noise detection device to verify whether the current background noise value is in a preset range. If the angle is within the preset range, the normal use of the electronic device will not be affected, and the rotation of the rotating device may be stopped, that is, the adjustment of the transmitting angle of the signal transmitting device (and/or the receiving angle of the signal receiving device) may be stopped. And the problem that the electronic equipment cannot be normally used due to external reasons or assembly reasons is solved through the method.
