Embodiment
The flow chart of the mode judging method that Fig. 1 provides for one embodiment of the invention, comprises following flow process, please refer to Fig. 1:
S101, inspected object close at least one predeterminated position in terminal close to distance.
Wherein, described predeterminated position can use the custom of terminal to arrange according to user under handset mode, such as, under handset mode, user usually needs handheld terminal and the earpiece module on front is pressed close to ear, therefore, can arrange described predeterminated position in terminal front side and the back side.Preferably, using palm time hand-held on the terminal back side can covering position as one of them predeterminated position, using position near earpiece module in terminal front side as another predeterminated position, each predeterminated position arrange one distance detection module, can detect this position of object proximity close to distance.Distance detection module can be range sensor, infrared technology, ultrasonic technology or capacitive proximity detection technique can be utilized to find range, find range to utilize ultrasonic technology, outwards launch ultrasonic wave in real time or regularly, start timing in transmitting, ultrasonic wave is propagated in atmosphere simultaneously, return after running into object, stopping timing immediately when receiving echo, according to launching ultrasonic wave and the time difference receiving echo, calculating the distance of transducer to object.
Whether the close distance of each predeterminated position of object proximity that S102, judgement detect meets preset requirement, if meet preset requirement, then enters step S103, if do not meet preset requirement, then returns step S101.
Including, but not limited to following cited:
By comparing with corresponding predetermined threshold value close to distance of each for the object proximity detected predeterminated position; If the close distance of each predeterminated position of object proximity is all less than or equal to the threshold value corresponding with it, then meet preset requirement.Due under handset mode, user's handheld terminal and the earpiece module on front is pressed close to ear use time, the distance in terminal between diverse location from human body is different, therefore, in order to improve accuracy, for each predeterminated position, corresponding threshold value can be preset.Certainly, for the terminal not high for accuracy requirement or user, also same threshold value can be set, comparing each for object proximity predeterminated position close to the same threshold value of distance and this.Threshold value obtains by the mode of test or estimation.
For step S101 inspected object close to the terminal back side close to Distance geometry object proximity terminal front side close to distance, comparing the described object proximity terminal back side detected with default first threshold value close to distance, comparing with default second threshold value close to distance of the described object proximity terminal front side detected; If the described object proximity terminal back side detected be less than or equal to described first threshold value close to distance, and the described object proximity terminal front side detected be less than or equal to described second threshold value close to distance, be then judged as meeting preset requirement.Preferably, being specially close to distance of object proximity terminal front side: earpiece module close to distance in object proximity terminal front side, being specially close to distance of the object proximity terminal back side: time hand-held on the object proximity terminal back side palm can covering position close to distance, the accuracy of mode decision can be improved so further.First threshold value, the second threshold value can be identical or different, and the mode by test or estimation obtains.
If S103 meets preset requirement, be then judged as that described terminal is current and be in handset mode.

The range value of S202, acquisition terminal earpiece module voice signal to be output.Including, but not limited to: the range value of the voice signal after the signal amplification module be connected with earpiece module in acquisition terminal amplifies.
S203, the range value of voice signal to be output for the earpiece module collected to be compared with default 3rd threshold value, if the range value of the earpiece module collected voice signal to be output is equal to or greater than described 3rd threshold value, then enter step S204, otherwise, return step S202.
3rd threshold value obtains by the mode of test or estimation.Be usually less than the emergency exit limit value that representative's ear accepts the limit.If the range value of earpiece module voice signal to be output is equal to or greater than described 3rd threshold value, then shows that the range value of earpiece module voice signal to be output is excessive, can hearing be damaged.
S204, execution hearing protection.
