The earphones may include an earbud earphone, which is widely used because it is very convenient to use outside due to its smaller size. With the development of technology, the earbud earphone is improved from acquiring a sound signal through a wired connection to acquiring a sound signal through a wireless connection. No matter be wired connection or wireless connection, earplug formula earphone's size is all by the manufacturing side according to the human design, but because individual difference, everyone's ear position, duct size and skull size are all inequality, and everyone wears the habit different moreover, has all led to hardly to guarantee that everyone has better centre gripping effect after wearing the earphone, and then can't guarantee the result of use of earphone.

In the using process of the earphone, when a user speaks (for example, speaks), the fitting degree between the earphone and the ear bones can be represented by detecting ear bone signals, so that whether the earphone is suitable to be worn or not is judged. If the ear bone signals of the user are detected and acquired, the acquired ear bone signals show the following characteristics due to improper wearing of the headset: 1) The amplitude of the signal is reduced; 2) The magnitude of the dc offset component in the signal changes. Based on the characteristics, the ear bone signals can be analyzed, whether the position of the earphone needs to be adjusted or not is judged based on the amplitude of the ear bone signals in the reference direction, and whether the angle of the earphone needs to be adjusted or not is judged based on the direct current bias component of the ear bone signals in the reference direction so as to calibrate the wearing position of the earphone, ensure that the position of the earphone is in a proper range for each person, avoid the earphone from slipping off and influence the using effect of the earphone.

Specifically, the earphone detects an ear bone signal of a user, and then transmits the ear bone signal to any personal terminal or cloud terminal, and the any personal terminal or cloud terminal judges whether the position of the earphone needs to be adjusted according to the amplitude of the ear bone signal in the reference direction; and prompting a user to adjust the angle of the earphone based on the direct current offset component of the ear bone signal in the reference direction, and finally enabling the earphone to be worn and calibrated.

The bone conduction sensor converts the collected bone vibration signals into electric signals in the speaking process of a person by clinging to the skin of the skull, and outputs the electric signals in real time in the x, y and z axes of the 3d position. As shown in fig. 2, fig. 2 shows an example of the direction of an ear bone signal according to an embodiment of the present invention.

When a user is in a speaking state, sound waves can be transmitted through the skull, the bone labyrinth, the inner ear lymphatic fluid transmission, the spiral organ, the auditory nerve and the auditory center of a person, namely, the sound is converted into mechanical vibration with different frequencies. At this time, when the user continuously makes a sound during wearing the earphone, i.e., the user is in a speaking state, as shown in fig. 3, fig. 3 shows a schematic diagram of the earphone according to the embodiment of the present invention, a sensor may be built in the near-ear side of the earphone, and the sensor is tightly attached to the skin of the ear bone, which may reflect the degree of fit between the earphone and the ear.

In some embodiments, the ear bone signal includes a first amplitude and a first dc offset component in an X-axis direction centered on the sensor, a second amplitude and a second dc offset component in a Y-axis direction centered on the sensor, and no signal in a Z-axis direction of a standard coordinate axis; then, the first amplitude value and the second amplitude value may be compared, and the direction corresponding to the larger amplitude value is taken as the reference direction, for example, if the amplitude value is larger than the second amplitude value, the X-axis direction is selected as the reference direction.
In some embodiments, the ear bone signal includes the second amplitude and the second dc bias component only in the Y-axis direction centered on the sensor, and there is no signal in the other two directions, the X-axis and the Y-axis, so the Y-axis direction can be directly selected as the reference direction.
It should be understood that the above embodiments are merely illustrative, and the ear bone signal may have a signal in at least one of the X-axis, Y-axis, or Z-axis, and when the ear bone signal has a signal in only one direction, the direction is directly selected as the reference direction; when the ear bone signal has signals in a plurality of directions, the direction with the largest amplitude is selected as the reference direction.
Optionally, the method further comprises: and when the amplitude of the ear bone signal in the reference direction is smaller than or equal to the preset threshold, sending a second prompt to prompt a user to adjust the position of the earphone.

In some embodiments, when the amplitude of the ear bone signal in the reference direction is smaller than or equal to the preset threshold, it indicates that the position of the earphone needs to be adjusted, and at this time, the user may be prompted to adjust the position of the earphone; further, after the user has adjusted the position of the headset. And acquiring the ear bone signals of the user again, judging whether the position of the earphone after the adjustment is proper, if so, continuing to adjust the position of the earphone and then judging again until the position of the earphone is judged to be not required to be adjusted through the ear bone signals acquired in real time. In this case, the obtaining of the ear bone signal of the user may be continuously maintained, or the obtaining of the ear bone signal of the user may be stopped, which is not limited herein.
According to the embodiment of the present invention, in step S130, the issuing a first prompt based on the dc offset component of the ear bone signal in the reference direction to prompt a user to adjust the angle of the earphone includes:
judging whether the direct current offset component of the ear bone signal in the reference direction is smaller than a direct current preset threshold value or not;
if the direct current offset component of the ear bone signal in the reference direction is smaller than the direct current preset threshold, not adjusting the angle of the earphone;
and/or if the direct current offset component of the ear bone signal in the reference direction is greater than or equal to the direct current preset threshold, sending the first prompt to prompt a user to adjust the angle of the earphone.
The direct current offset component, namely the direct current level component in each direction in the ear bone signal can reflect the actual deflection angle of the direction and the standard coordinate axis, so that the angle of the earphone can be reflected, and whether the angle of the earphone is proper or not can be judged. It should be understood that the ear bone signal is an electrical signal, and obtaining the dc component from the electrical signal is a conventional technical means in the art and will not be described herein.
Optionally, the angle of the earphone is adjusted based on the first prompt until the dc offset component of the ear bone signal in the reference direction is smaller than the dc preset threshold.

Optionally, the method further comprises: and when the angle of the earphone does not need to be adjusted, ending the method. Further, the user may also be prompted when the angle of the headset does not need to be adjusted.
In some embodiments, the first prompt may include: voice prompts or music prompts. For example, a first voice prompt "headset fit", or a first music form (e.g., relatively sharp music may be used to indicate that the angle of the headset needs to be adjusted, while relatively slow music may be used to indicate that the angle of the headset does not need to be adjusted), etc.
In some embodiments, when neither the position nor the angle of the headset needs to be adjusted, the user may also not be prompted.
In one embodiment, whether the position of the earphone needs to be adjusted or not can be prompted, and then whether the angle of the earphone needs to be adjusted or not can be prompted. For example, the user is prompted to adjust the position of the earphone by a prompt sound a ("ask for earphone position adjustment" or cued music), after the user adjusts the position of the earphone, the user is prompted to adjust the position of the earphone without the need of adjusting the position of the earphone by a prompt sound B ("earphone position proper" or short sound "tic"), and then the user is prompted to adjust the angle of the earphone by a prompt sound C ("ask for earphone angle adjustment" or relaxed music), after the user adjusts the angle of the earphone, the user is prompted to adjust the angle of the earphone without the need of adjusting the angle of the earphone by a prompt sound D ("earphone angle proper" or long sound "tic"), and the earphone of the user is worn at a position suitable for the user, so that different users can be guaranteed to have good effect of holding the earphone, and the use effect of the earphone is greatly improved.

In some embodiments, the ear bone signal includes a first amplitude and a first dc offset component in an X-axis direction centered on the sensor, a second amplitude and a second dc offset component in a Y-axis direction centered on the sensor, and no signal in a Z-axis direction of a standard coordinate axis; then, the first amplitude value and the second amplitude value may be compared, and the direction corresponding to the larger amplitude value is taken as the reference direction, for example, if the first amplitude value is larger than the second amplitude value, the X-axis direction is selected as the reference direction.
In some embodiments, the ear bone signal includes the second amplitude and the second dc bias component only in the Y-axis direction centered on the sensor, and there is no signal in the other two directions, the X-axis and the Y-axis, so the Y-axis direction can be directly selected as the reference direction.
It should be understood that the above embodiments are only examples, and the ear bone signal may have a signal in at least one of the X-axis, the Y-axis, or the Z-axis, and when the ear bone signal has a signal in only one direction, the direction is directly selected as the reference direction; when the ear bone signal has signals in a plurality of directions, the direction having the largest amplitude is selected as the reference direction.
Optionally, the prompting module 530 is further configured to: and when the amplitude of the ear bone signal in the reference direction is smaller than or equal to the preset threshold, sending a second prompt to prompt a user to adjust the position of the earphone.
In some embodiments, the second prompt may include: voice prompts or music prompts.
Optionally, the obtaining module 510 is further configured to: the ear bone signals of the user are continuously acquired.
In some embodiments, when the amplitude of the ear bone signal in the reference direction is smaller than or equal to the preset threshold, it indicates that the position of the earphone needs to be adjusted, and the prompting module 530 may prompt the user to adjust the position of the earphone; further, after the user has adjusted the position of the headset. The obtaining module 510 obtains the ear bone signal of the user again, and the determining module 520 determines whether the position of the earphone after the adjustment is suitable, if the position of the earphone still needs to be adjusted, the position of the earphone continues to be adjusted, and then the determination is performed again until the real-time ear bone signal obtained by the obtaining module 510 determines that the position of the earphone does not need to be adjusted. In this case, the obtaining of the ear bone signal of the user may be continuously maintained, or the obtaining of the ear bone signal of the user may be stopped, which is not limited herein.
According to the embodiment of the present invention, the prompting module 530 issues a first prompt to prompt a user to adjust the angle of the headset based on the dc offset component of the ear bone signal in the reference direction, including:
judging whether the direct current offset component of the ear bone signal in the reference direction is smaller than a direct current preset threshold value or not;
if the direct current offset component of the ear bone signal in the reference direction is smaller than the direct current preset threshold, not adjusting the angle of the earphone;
and/or if the direct current offset component of the ear bone signal in the reference direction is greater than or equal to the direct current preset threshold, sending the first prompt to prompt a user to adjust the angle of the earphone.
The direct current offset component, namely the direct current level component in each direction in the ear bone signal can reflect the actual deflection angle of the direction and the standard coordinate axis, so that the angle of the earphone can be reflected, and whether the angle of the earphone is proper or not can be judged. It should be understood that the ear bone signal is an electrical signal, and obtaining the dc component from the electrical signal is a conventional technical means in the art and will not be described herein.
Optionally, the angle of the earphone is adjusted based on the first prompt until the dc offset component of the ear bone signal in the reference direction is smaller than the dc preset threshold.
It should be noted that the dc preset threshold may be set as needed, and is not limited herein.
Optionally, the prompting module 530 is further configured to: and prompting a user when the angle of the earphone does not need to be adjusted.
In some embodiments, the first prompt may include: voice prompts or music prompts. For example, a first voice prompt "headset fit", or a first music form (e.g., relatively sharp music may be used to indicate that the angle of the headset needs to be adjusted, while relatively slow music may be used to indicate that the angle of the headset does not need to be adjusted), etc.
In some embodiments, the prompting module 530 may also not prompt the user when neither the position nor the angle of the headset needs to be adjusted.
In one embodiment, the prompt module 530 may prompt whether the position of the earphone needs to be adjusted first, and then prompt whether the angle of the earphone needs to be adjusted. For example, the user is prompted to adjust the position of the earphone by a prompt sound a ("ask for earphone position adjustment" or cued music), after the user adjusts the position of the earphone, the user is prompted to adjust the position of the earphone without the need of adjusting the position of the earphone by a prompt sound B ("earphone position proper" or short sound "tic"), and then the user is prompted to adjust the angle of the earphone by a prompt sound C ("ask for earphone angle adjustment" or relaxed music), after the user adjusts the angle of the earphone, the user is prompted to adjust the angle of the earphone without the need of adjusting the angle of the earphone by a prompt sound D ("earphone angle proper" or long sound "tic"), and the earphone of the user is worn at a position suitable for the user, so that different users can be guaranteed to have good effect of holding the earphone, and the use effect of the earphone is greatly improved.
