Embodiment 1

[0019] refer to figure 1 , shows a flow chart of steps of a method for reducing specific absorption rate according to Embodiment 1 of the present invention.

[0020] The method for reducing the specific absorption rate provided by the embodiments of the present invention comprises the following steps:

[0021] Step 101: Detect the current processing task of the mobile terminal.

[0022] Among them, processing tasks include voice tasks and data traffic tasks

[0023] Step 102: When it is detected that the current processing task of the mobile terminal is a voice task, the first antenna is used as a diversity receiving antenna, and the second antenna is used as a transmitting antenna.

[0024] The mobile terminal has different states in different operation modes. When the user uses the mobile terminal to perform a voice task, the mobile terminal will detect that when the mobile terminal is processing the voice task, the first antenna will be used as the receiving antenna of th...

Embodiment 2

[0032] refer to figure 2 , shows a flow chart of the steps of a method for reducing the specific absorption rate in Embodiment 2 of the present invention.

[0033] The method for reducing the specific absorption rate provided by the embodiments of the present invention comprises the following steps:

[0034] Step 201: Detect the current processing task of the mobile terminal.

[0035] Wherein, the processing tasks include voice tasks and data traffic tasks.

[0036] Step 202: When detecting that the current processing task of the mobile terminal is a voice task, send a first control signal to the dual-antenna control unit.

[0037] The mobile terminal has different states in different operation modes. When the user uses the mobile terminal for voice service, the mobile terminal will detect that the current mobile terminal is processing the voice service, and will send the first control signal to the dual-antenna control unit.

[0038] Wherein, the first control signal is s...

Embodiment 3

[0053] refer to Figure 4 , shows a structural block diagram of a mobile terminal according to Embodiment 3 of the present invention.

[0054] The mobile terminal provided by the embodiment of the present invention includes: a detection module 401, configured to detect the current processing task of the mobile terminal, wherein the processing task includes a voice task and a data flow task first calling module 402, configured to detect When the current processing task of the mobile terminal is a voice task, the first antenna is used as a diversity receiving antenna, and the second antenna is used as a transmitting antenna; the second calling module 403 is used to detect that the current processing task of the mobile terminal is For data tasks, the first antenna is used as a transmitting antenna, and the second antenna is used as a diversity receiving antenna.

[0055] In the mobile terminal provided by the embodiment of the present invention, when the current processing task ...

Abstract

The invention provides a method for reducing a specific absorption rate. The method comprises: when a voice task is detected, a first antenna is used as a diversity receiving antenna and a second antenna is used as a transmitting antenna; when a data task is detected, the first antenna is used as a transmitting antenna and the second antenna is used as a diversity receiving antenna. The first antenna is arranged at the top of a mobile terminal and the second antenna is arranged at the bottom of the mobile terminal. Therefore, the first antenna and the second antenna are invoked according to the current state of the terminal; and the two antennas can be used as a receiving antenna and a transmitting antenna respectively instead of being used as receiving antennas or transmitting antennas simultaneously when the mobile terminal is processing either a voice service or a data service, so that the specific absorption rate (SAR) value can be reduced. While the SAR value is reduced, the antennas can work normally; and thus the wireless connection performance is not affected when the SAR value is reduced.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a method for reducing the specific absorption rate and a mobile terminal. Background technique [0002] With the development of wireless communication technology, the equipment that emits electromagnetic waves has increased rapidly, and the public is increasingly concerned about safety issues. Although the energy emitted by wireless communication devices such as mobile phones and notebooks is low during normal operation, these handheld devices are very close to human tissue during normal operation, and an induced electromagnetic field will be generated in the human body. At present, the industry has introduced SAR (Specific Absorption Rate, compared to Absorption rate) to characterize the degree of influence of electromagnetic radiation on the human body. [0003] SAR is defined as the electromagnetic power absorbed or consumed by a unit mass of human tissue within a unit time....
