Description

A method, device and mobile terminal for reducing mobile phone radiation

technical field

The invention relates to the communication field, in particular to a method, a device and a mobile terminal for reducing mobile phone radiation.

Background technique

When a cell phone is used to make a call, it emits radio waves (also known as radio frequency energy) that can be picked up by the nearest base station. Once the base station receives the radio waves from the mobile phone, it will be transmitted to the switching station, and the switching station will transfer the call to another base station or fixed telephone line network according to the type of the current call, so as to realize the call. This is the essence of mobile communication. Basic working principle. When people use mobile phones, the mobile phone will transmit radio waves to the base station, and any kind of radio waves will be more or less absorbed by the human body, thereby changing human tissues and possibly affecting human health. These radio waves are called Radiation from mobile phones.

Mobile phone radiation is measured by Specific Absorption Rate (SAR). SAR represents the amount of radiation allowed to be absorbed by organisms (including the human body) per unit kilogram. Its value indicates the impact of radiation on the human body and is the most direct test value. SAR has data for the whole body, parts, and extremities; the lower the SAR value, the less radiation is absorbed. Among them, the SAR standard value for the brain must be lower than 1.67 watts to be considered safe.

Generally speaking, the farther the mobile phone is from the human body, the smaller the radiation. When people use a mobile phone, in order to clearly hear the sound from the microphone, they either directly touch the cheek with the mobile phone, or make an angle of about 15° between the mobile phone and the cheek with one end of the mobile phone. If the distance between the mobile phone and the cheek is widened in order to reduce the radiation of the mobile phone, it is not easy to hear the sound from the handset of the mobile phone clearly.

For people's habit of using mobile phones, since there is no mobile phone that reduces SAR in the prior art, the radiation of mobile phones to the human body is relatively serious.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

Please refer to accompanying drawing 1, which is a schematic flow chart of a method for reducing mobile phone radiation provided by an embodiment of the present invention, which mainly includes steps:

S101. Detect the distance from the mobile phone to the cheek of the user.

In the embodiment of the present invention, a sensor, such as an infrared sensor or a thermal sensor, can be used to detect the distance from the mobile phone to the user's cheek during a call. It is also possible to use other devices or modules with a distance detection function to detect the distance from the mobile phone to the user's cheek during a call, which is not limited in the present invention.

S102. Comparing the distance from the mobile phone to the user's cheek with a preset distance to learn whether the distance from the mobile phone to the user's cheek matches the preset distance.

The preset distance is an empirical value or a strictly calculated value, and the preset distance is the distance from the mobile phone to the user's cheek when the radiation absorption rate of the mobile phone is the smallest during a call.

In an embodiment of the present invention, the preset distance is a fixed value, for example, 3.5 cm (centimeter). When comparing the distance from the mobile phone to the user's cheek with the preset distance, specifically compare the distance from the mobile phone to the user's cheek with the fixed value, for example, compared with 3.5cm, if the mobile phone to the user The cheek distance is not equal to the predetermined value, that is, the distance from the mobile phone to the user's cheek is considered to be inconsistent with the preset distance. For example, if it is detected that the distance from the mobile phone to the user's cheek is 4cm, the distance from the mobile phone to the user's cheek obviously does not match the preset distance (3.5cm).

In another embodiment of the present invention, the preset distance is within a range, for example, 2 cm (centimeter) to 5 cm (centimeter). When comparing the distance from the mobile phone to the user's cheek with the preset distance, specifically compare the distance from the mobile phone to the user's cheek with the preset range, for example, with [2, 5] cm (representing 2 cm 5cm, including 2cm and 5cm), if the distance from the mobile phone to the user's cheek is not within the range, it is considered that the distance from the mobile phone to the user's cheek does not match the preset distance. For example, if it is detected that the distance from the mobile phone to the user's cheek is 1.5cm or 6cm, then its size is obviously not within [2, 5] (cm), that is, the distance from the mobile phone to the user's cheek does not match the preset distance.

S103, if the distance from the mobile phone to the user's cheek does not match the preset distance, the mobile phone outputs abnormal information.

In one embodiment of the present invention, if the distance from the mobile phone to the user's cheek does not match the preset distance, for example, it is detected that the distance from the mobile phone to the user's cheek is 4cm, while the preset distance is 3.5cm, or, It is detected that the distance from the mobile phone to the user's cheek is 1.5cm or 6cm, and the preset distance is [2, 5]cm, then the sound output by the handset of the mobile phone becomes smaller or even silent. At this time, the user will consciously adjust the mobile phone to The distance from their cheeks, for example, decreases or increases the distance from the phone to their cheeks.

In one embodiment of the present invention, if the distance from the mobile phone to the user's cheek does not match the preset distance, for example, it is detected that the distance from the mobile phone to the user's cheek is 3cm, and the preset distance is 3.5cm, or, It is detected that the distance from the mobile phone to the user's cheek is 1cm or 5.5cm, and the preset distance is [2, 5]cm, then the handset of the mobile phone will output the mobile phone output prompt tone, for example, output "Please increase the distance between the mobile phone and your cheek " or "Please reduce the distance between the mobile phone and your cheek", at this time, the user will adjust the distance between the mobile phone and his cheek according to the output prompt tone, for example, increase or decrease the distance between the mobile phone and his cheek.

It can be seen from the above-mentioned embodiments of the present invention that when a user uses a mobile phone to talk, the mobile phone can compare the detected distance from the mobile phone to the user's cheek with the preset distance, if the distance from the mobile phone to the user's cheek is compared with the preset distance If the distance does not match, the mobile phone outputs abnormal information. At this time, the user can adjust the distance between the mobile phone and his cheek until the mobile phone no longer outputs abnormal information. Since the preset distance is the distance from the mobile phone to the user's cheek when the radiation absorption rate of the mobile phone is the smallest during a call, the method provided by the invention can minimize the radiation of the mobile phone while ensuring that the voice is normal. and its harm to the human body.
