When the wearer wears the intelligent glasses with audio playing, the intelligent glasses are provided with the sound outlet holes, and the sound outlet holes of the intelligent glasses are required to be not too close to or too far from the ear holes of the wearer when the hearing effect of the wearer is required to be guaranteed.
In the related art, after the wearer wears the glasses, the wearer adjusts the temples to the proper position according to the sensory recognition, but since it is difficult for the wearer to adjust the glasses to the proper position once, the repeated adjustment requires a lot of time and effort.

Further, the embodiment of the present application provides a method for adjusting the length of a leg, as shown in fig. 1, and an example is given to perform a method for adjusting the length of a leg, which is specifically shown as follows:
step S101, a first position of a contact point of the glasses hanging ear portion and the ear portion is acquired, and a second position of a contact point of the glasses nose frame portion and the nose portion corresponding to the glasses hanging ear portion is acquired.
For this application embodiment, glasses include picture frame and lens, and wherein, the picture frame includes mirror leg and glasses nose frame portion, and the mirror leg includes glasses string ear portion and can adjust the flexible portion of mirror leg length.
The glasses leg sensor used for acquiring the first position is arranged on the glasses hanging ear in advance, and the nose pad sensor used for acquiring the second position is arranged on the glasses nose frame part. The temple sensor and the nose pad sensor may be position sensors, and the position sensors include a contact position sensor and a proximity position sensor, which are not limited in the embodiment of the present application. It should be noted that, in order to be able to accurately acquire the first position and the second position, the position sensor is a multipoint sensor.
Specifically, when the sensor is a contact position sensor, and the contact of the contact position sensor is pressed by the glasses legs and the ears of the wearer together to generate pressure, the contact position sensor collects the positions of the contact points of the glasses legs and the ears of the wearer, and sends the positions of the contact points to the electronic equipment as a first position.
Step S102, determining a distance between the first position and the second position.
For the embodiment of the application, the first coordinate of the first position is (X1, Y1, Z1) acquired by the temple sensor, the second coordinate of the second position is (X2, Y2, Z2) acquired by the nose pad sensor, the distance between the first position and the second position is determined to be L1, and the distance L1 between the first position and the second position is calculated according to the formula that the distance is obtained by the first coordinate, the second coordinate and the two-point coordinates. The formula for obtaining the distance by the coordinates of two points can be as follows:
step S103, the current user information is read, and the preset volume at the ear hole of the user is obtained.
The preset volume is a target volume of the user in the ear hole under the playing audio.
For the present embodiment, the current user information includes a user identifier, which includes, but is not limited to, a user name, a user ID, a user identification card number, and a user fingerprint, as long as the user identifier is information uniquely representing the user identity. The preset volume is the target volume of the user in the ear hole under the play audio, and the hearing effect of the user is good under the target volume.
Step S104, according to the current user information and the preset volume at the ear hole of the user, determining a corresponding target distance range from the corresponding relation among the pre-stored user information, volume and distance range.

The target distance range is a standard distance range of the first location and the second location.
For glasses capable of playing audio, a sound outlet hole is formed in a glasses leg close to the ear hole, and when the preset volume of the ear hole of the user is the target volume of the ear hole of the user under the playing audio, the glasses indicate that the glasses have better sound effect under the current situation, and at the moment, the distance range from the corresponding sound outlet hole to the ear hole is the sound effect preset range.
It can be understood that after playing the audio, the actual volume at the ear hole of the user is the preset volume, the distance between the first position and the second position is within the target distance range, and meanwhile, the distance range from the sound outlet to the ear hole is the sound effect preset range by adjusting the length of the glasses leg. It is understood that the specific relationship among the three is data obtained through multiple experiments according to multiple samples.
Specifically, there is a correspondence between user information, volume, and target distance. For example, if the current user information is "Zhang San", when the volume corresponding to Zhang Sanhe is volume 1, the volume 1 corresponds to the target distance LB1-LB2; when the volume corresponding to the user Zhang three is volume 2, the target distance corresponding to the volume 2 is LB3-LB4; if the current user information is "Li four", when the volume corresponding to Li four of the user is volume 3, the target distance corresponding to volume 3 may be LB1-LB2, LB3-LB4, or LB5-LB6; when the volume corresponding to the user Li four is the volume 4, the target distance corresponding to the volume 4 may be LB1-LB2, LB3-LB4, LB6-LB7.
When the adjusted distance is in LB1-LB2, the distance between the sound outlet hole and the ear hole is in LA1-LA2, which is the distance range with better sound effect.
Step S105, according to the distance between the first position and the second position, sending an adjusting instruction to the telescopic part of the glasses leg.

Specifically, when the volume of the environment where the glasses are located is larger, that is, the surrounding environment is louder, and/or when the space where the glasses are located is larger, that is, the surrounding environment is more open, the corresponding correction coefficient is larger. For example, when the volume of the environment where the glasses are located is less than 60 db, that is, the environment where the glasses are located is quite, the current environment has little influence on the sound effect, and the correction coefficient is 1; when the volume of the environment is 60-100 dB, namely the environment of the glasses is noisy, the current environment has influence on the sound effect, and the correction coefficient is 1.2; when the environmental sound effect is 100-150 db, namely the environment where the glasses are located is noisy, the current environment has great influence on the sound effect, and the correction coefficient is 1.5.
