When the content of the impurities on the filter screen 4 or around the filter screen 4 is lower than the second preset value, the impurities on the filter screen 4 or around the filter screen 4 are considered to be too few (or even completely cleaned), a second prompt sound can be sent out (such as "the impurities are cleaned", "the impurities are cleaned completely", and the like), so that a user is reminded that the impurities on the filter screen 4 or around the filter screen 4 are cleaned completely, and the filter screen can be normally used subsequently. And when the content of the impurities on the filter screen 4 or around the filter screen 4 is between the first preset value and the second preset value, a third prompt sound is given (such as 'the earphone generates impurities', 'the impurities are to be cleaned', and the like).
In order not to affect the user experience, the interval time for emitting the first prompt sound, the second prompt sound, or the third prompt sound may also be set, specifically, the prompt interval time for emitting any one of the first prompt sound, the second prompt sound, or the third prompt sound may be set to be 1 to 5 hours, for example, the interval time may be 1 hour, 3 hours, 5 hours, and the like.
The first preset value and the second preset value can be determined according to actual conditions, for example, the first preset value can be 50% to 100% (for example, it can be 50%, 80%, 100%, etc., and is selected to be 50% in the embodiment of the present application) of the surface area of the filter screen 4; the second preset value may be less than 10% of the surface area of the filter web 4, for example, it may be 5%, 8%, etc. (even 0, if 0, it indicates that there is no impurity on the filter web 4), and in the embodiment of the present application, it is selected to be 5%.
As an embodiment, when the impurity detector detects that the impurity content on the filter screen 4 or around the filter screen 4 is higher than the first preset value, the earphone may automatically perform the ash removal process, or may be manually triggered by a user to perform the ash removal process, such as performing a key operation on a volume key on the earphone (specifically, performing long-press operations on the volume key of the earphone for 5s, 10s, and the like).
