Detailed Description
in order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
as shown in fig. 1-2, the method for intelligently listening to ambient sound by using an earphone according to the present invention is characterized by comprising the following specific steps:
acquiring the current moving speed of the earphone; if the moving speed is larger than or smaller than a preset threshold value, determining the moving speed as a safe speed, and if the moving speed is within the range of the preset threshold value, determining the moving speed as a dangerous speed; when the dangerous speed is judged, starting a microphone to pick up ambient sound; converting the ambient sound into an audio signal; and decoding the audio signal and sending the audio signal to a headphone for playing.
Specifically, the current moving speed of the earphone wearer is measured, the earphone can be wired or wireless, the wired earphone is connected with the mobile phone and senses the speed by using a self-carried speed measurer of the mobile phone, the wireless earphone can be connected with the mobile phone Bluetooth and uses the self-carried speed measurer of the mobile phone or a built-in sensing device of the earphone, the moving states of a general person are divided into static, slow, fast walking, running, riding or fast transportation, the earphones are dangerous states when the person walks, runs and rides, the lowest speed and the highest speed of the dangerous states under normal conditions are tested as threshold ranges, the speed in the threshold range is regarded as a dangerous speed, the speed outside the threshold range is regarded as a safe speed, when the dangerous speed is judged, the microphone is automatically started to pick up ambient sound, the ambient sound is converted into an audio signal, and the audio signal is decoded and sent to an earphone receiver to be played, the earphone wearer can better feel the ambient sound and avoid accidents.
in some embodiments, the method further comprises: and presetting a dangerous position, acquiring current position information of the earphone, and if the current position information is the preset dangerous position and the moving speed is less than a preset threshold value, starting a microphone to pick up ambient sound and entering the next step. Specifically, the dangerous position comprises a road, a traffic light, an intersection and the like, the current position of the earphone wearer is obtained by obtaining gps information through the gps carried by the earphone or a link mobile phone, and if the current position is in the dangerous position, although the current position is in a safe speed state, the microphone is still started to pick up ambient sound so as to guarantee the safety of the wearer.
in some embodiments, the acquiring the current moving speed of the headset includes: acquiring the acceleration of each time period of the X/Y/Z axis of the earphone, acquiring the angular speed of the X/Y/Z axis of the earphone, and obtaining the moving speed according to the acceleration and the angular speed. Specifically, the gyroscope acquires angular velocity of the X/Y/Z axis by acceleration of the X/Y/Z axis for each time period provided by the acceleration sensor: the acceleration change of the person at different walking positions can be judged, and therefore the activity of the person can be calculated. For example: when a person walks, a relatively stable non-uniform acceleration is present, which is completely different from the relatively stable acceleration when riding a vehicle. Therefore, the acceleration sensor can easily judge whether the person walks or rides the bicycle. After the three-axis gyroscope and the three-axis acceleration sensor form a six-axis motion sensor, basically all forms of motion can be detected, including parameters such as speed, direction, displacement and the like. "there are no more than six movements of the object, X, Y, Z displacement in three directions and X, Y, Z rotation in three directions. The six motion modes form a complete motion track of the object.
In some embodiments, a switch module is provided on the headset, which when opened, enables the microphone to pick up ambient sounds. When the user is at a dangerous speed but confirms that the environmental state is safe, such as a private sport place, the microphone is manually turned off and ambient sound is not picked up, and when the user needs to monitor the ambient sound, the switch is turned on, so that the monitoring of the ambient sound can be realized. It should be noted that, in the process of monitoring the ambient sound by the user, the speaker only plays the ambient sound, and the audio played before the user turns on the switch is in the state of pausing the playing, and when the user turns off the switch, the audio starts playing again.
In addition, the present invention also provides an earphone, including:
the speed calculation module is used for acquiring the current moving speed of the earphone;
the speed judging module is used for judging the moving speed to be a safe speed if the moving speed is larger than or smaller than a preset threshold value, and judging the moving speed to be a dangerous speed if the moving speed is within a preset threshold value range;
a sound capture module for activating a microphone to pick up ambient sounds when it is determined that there is a dangerous speed;
An audio conversion module for converting the environmental sound into an audio signal;
And the decoding module is used for decoding the audio signal and sending the audio signal to a headphone for playing.
it should be noted that the speed determination module needs to preset a maximum speed value X1 for people to walk and a minimum speed value X2 for automobile to drive, and then performs intelligent determination according to the obtained headset speed information and GPS location information, where the headset movement speed value is tentatively X, and the location information is Y (if GPS indicates that the headset wearer is inside the building, the value is 0; if the value is 1 near the road, and if the value is 2 in the road), the control information value sent to the sound capture module is R, and when X, Y has data, the following determination is performed:
X<x1 and Y＝0，R＝0
x1<X<x2 and Y＝0,R＝0
x1<X<x2 and Y＝1,R＝1
x1<X<x2 and Y＝2,R＝2
x>x2,R＝0
after receiving the message, the earphone clears the previous state.
if the R obtained by analysis is 0, the earphone is in a normal module, namely the earphone only plays the audio information of the mobile phone.
And if the R obtained by analysis is 1, the earphone microphone is turned on, the recorded sound is transmitted to the earphone to be played, and the audio data transmitted from the mobile phone is also played.
If the R obtained by analysis is 2, the earphone microphone is turned on, the recorded sound is transmitted to the earphone to be played, but the audio data transmitted by the mobile phone is not played.
in summary, the working principle of the invention is as follows:
the invention provides a method for intelligently monitoring environmental sounds by an earphone and the earphone, wherein the method comprises the following steps: acquiring the current moving speed of the earphone; if the moving speed is larger than or smaller than a preset threshold value, determining the moving speed as a safe speed, and if the moving speed is within the range of the preset threshold value, determining the moving speed as a dangerous speed; when the dangerous speed is judged, starting a microphone to pick up ambient sound; converting the ambient sound into an audio signal; and decoding the audio signal and sending the audio signal to a headphone for playing. Whether ambient sound is picked up or not is decided by judging the current speed of the earphone wearer, and the ambient sound is intelligently controlled, identified and obtained.
It should be understood that equivalents and modifications of the technical solution and inventive concept thereof may occur to those skilled in the art, and all such modifications and alterations should fall within the scope of the appended claims.
