Abstract

This application discloses a method for determining a wearing status of a wireless earphone and a wireless earphone. The method includes: obtaining a first output of a sensor system, where the first output indicates a moving status of a housing, and determining, based on the first output, whether a body portion is put in a user's ear. This application further discloses a method for determining a double-tapped status of a wireless earphone and a wireless earphone. The method includes: obtaining a first output of a sensor system, where the first output indicates a moving status of a housing, and determining, by using a neural network model and by using the first output as a model input, whether the housing is double-tapped by an external object. This application improves accuracy of identifying the wearing status of the wireless earphone and improves accuracy of identifying the double-tapped status of the wireless earphone.

First claim

What is claimed is:

1. A method for determining a wearing status of a wireless earphone, wherein the wireless earphone comprises a housing and a sensor system, the housing has a body portion and a handle portion extending from the body portion, and the method comprises:
obtaining a first output of the sensor system, wherein the first output indicates a moving status of the housing; and
determining, based on the first output, whether the body portion is put in a user's ear, wherein the determining, based on the first output, whether the body portion is put in a user's ear comprises:
if the first output further indicates at least that a vibration amplitude of the body portion is within a first preset range and a vibration frequency of the body portion is within a second preset range, determining that the body portion is put in the user's ear.

2. The method according to claim 1 , wherein the determining, based on the first output, whether the body portion is put in a user's ear further comprises:
if the first output further indicates at least that the body portion has a first state, determining that the body portion is put in the user's ear; wherein
the first state indicates that the body portion has a vibration state corresponding to a process of adjusting a position of the body portion in the user's ear.

3. The method according to claim 2 , wherein the first state indicates that the body portion changes from a moving state of moving to the ear to the vibration state corresponding to the process of adjusting the position of the body portion in the user's ear.

4. The method according to claim 1 , wherein the determining, based on the first output, whether the body portion is put in a user's ear comprises:
determining, by using a neural network model and by using at least the first output as an input to the neural network model, whether the body portion is put in the user's ear.

5. The method according to claim 1 , wherein the method further comprises:
obtaining a second output of the sensor system, wherein the second output indicates a blocked status of the body portion, and wherein the determining, based on the first output, whether the body portion is put in a user's ear comprises:
determining, based on the first output and the second output, whether the body portion is put in the user's ear.

6. The method according to claim 5 , wherein the determining, based on the first output and the second output, whether the body portion is put in the user's ear comprises:
if the first output further indicates that the body portion has a first state, and the second output further indicates at least that the body portion has a second state, determining that the body portion is put in the user's ear; wherein
the first state indicates that the body portion has a vibration state corresponding to a process of adjusting a position of the body portion in the ear, and the second state indicates that the body portion has a blocked state.

7. The method according to claim 6 , wherein the second state indicates that the body portion has a blocked state in which the body portion is blocked by the user's ear.

8. The method according to claim 6 , wherein the second state indicates that the body portion changes from an unblocked state to the blocked state in which the body portion is blocked by the user's ear.

9. The method according to claim 6 , wherein the second state indicates that a blocked state in which the handle portion is blocked by a hand is changed to the blocked state in which the body portion is blocked by the user's ear.

10. A wireless earphone comprising a housing, a sensor system, and a processor, wherein the sensor system is connected to the processor, and the housing has a body portion and a handle portion extending from the body portion; and
wherein the processor is configured to:
obtain a first output of the sensor system, the first output indicating a moving status of the housing, and
determine, based on the first output, whether the body portion is put in a user's ear, wherein the determine, based on the first output, whether the body portion is put in a user's ear comprises:
if the first output further indicates at least that a vibration amplitude of the body portion is within a first preset range and a vibration frequency of the body portion is within a second preset range, determining that the body portion is put in the user's ear.

11. The wireless earphone according to claim 10 , wherein the processor is further configured to: if the first output further indicates at least that the body portion has a first state, determine that the body portion is put in the user's ear; wherein
the first state indicates that the body portion has a vibration state corresponding to a process of adjusting a position of the body portion in the user's ear.

12. The wireless earphone according to claim 11 , wherein the first state indicates that the body portion changes from a moving state of moving to the ear to the vibration state corresponding to the process of adjusting the position of the body portion in the user's ear.

13. The wireless earphone according to claim 10 , wherein the processor is further configured to determine, by using a neural network model and by using at least the first output as an input to the neural network model, whether the body portion is put in the user's ear.

14. The wireless earphone according to claim 10 , wherein the processor is further configured to:
obtain a second output of the sensor system, the second output indicating a blocked status of the body portion; and
determine, based on the first output and the second output, whether the body portion is put in the user's ear.

15. The wireless earphone according to claim 14 , wherein the processor is further configured to:
if the first output further indicates that the body portion has a first state, and the second output indicates at least that the body portion has a second state, determine that the body portion is put in the user's ear; wherein
the first state indicates that the body portion has a vibration state corresponding to a process of adjusting a position of the body portion in the ear, and the second state indicates that the body portion has a blocked state.

16. The wireless earphone according to claim 15 , wherein the second state further indicates that the body portion has a blocked state in which the body portion is blocked by the user's ear.
