in step S311, if the distance between the speaker and the ear is greater than the maximum value of the preset distance, the user is prompted to check the position state of the wearable device. The loudspeaker in the wearable equipment launches the sound wave, because the sound wave is mechanical wave, the sound wave is energy in the in-process of transmission and is reduced gradually, and the distance between user's human ear and the speaker exceeds certain range from this, and the human ear can't hear clearly the sound. When the wearing position of the user is incorrect, so that the distance between the loudspeaker and the ear of the user is too large, a prompt needs to be sent to the user, and therefore the effectiveness of the sound is further ensured. The prompting mode can be a voice prompt, a vibration prompt, a music prompt and the like. The user can check the position of the wearable device and send an adjustment completion prompt after the wearable device is correctly adjusted.

In addition, a safe distance can be set, in order to reduce misjudgment of the speaker on the position of the human ear and reduce the possibility that the speaker regards a peripheral object as the human ear, and only a measured value within the safe distance is understood as the distance between the speaker and the human ear.
Referring to fig. 8, on the basis of the sixth embodiment of the present invention, a seventh embodiment of the present invention is proposed, which further includes, after the step of comparing the distance between the speaker and the ear with the preset distance:
in step S312, if the distance between the speaker and the ear is greater than the maximum value of the preset distance, and the difference between the distance between the speaker and the ear and the preset distance exceeds the preset threshold, the audio signal of the speaker is cut off. When the user uses the wearable device, the user needs to take the wearable device off in some cases. For example, a user needs to remove the wearable device in order to represent respect when communicating with a person. At this time, the wearable device is in normal operation, and the speaker still plays sound, so easily cause the loss of power. After the user takes off the wearable device, the positions of the loudspeaker and the ear of the user can be gradually increased. The difference between the distance between the loudspeaker and the ear of the person and the value of the preset distance is calculated, the difference value is compared with a preset threshold value, if the difference value is smaller than the preset threshold value, the loudspeaker is continuously maintained to normally operate, if the difference value exceeds the preset threshold value, the power supply of the wearable equipment is turned off, then the audio signal of the loudspeaker is cut off, and the loss of electric power is reduced. The preset threshold value can be changed and set according to the needs of the user. For example, the preset threshold may be 5cm, 10cm, or the like.
On the basis of the above embodiment of the present invention, an eighth embodiment of the present invention is proposed, in which the plurality of preset distances are sequentially arranged from small to large at equal intervals. Each preset distance corresponds to one adjusting parameter, and the loudspeaker adjusting parameters are orderly classified through the equal-interval distribution of the preset distances. Therefore, the adjustment direction of the audio signal can be clearly obtained through the arrangement of equal intervals from small to large. And when the adjusting parameters are obtained in advance, the method is quicker.
