The leakage adjusting module 220 has a shielding member, and can change the gear for shielding the front leakage hole 130 of the earphone under the control of the wearing detecting module 210, so as to compensate the noise reduction effect according to the degree of tightness of wearing of the earphone. When the earphone is worn loosely, the shielding degree of the front leakage hole 130 is improved, and the volume leakage of the front leakage hole 130 is reduced to compensate the volume of the sound outlet 120; when the earphone is worn too tightly, the shielding degree of the front leakage hole 130 is reduced, and the volume leakage of the front leakage hole 130 is increased to balance the volume of the sound outlet 120, so that the active noise reduction effect of the earphone is improved.
In some embodiments of the present application, the wearing detection module 210 may collect sound using a feedback noise reduction microphone (FB MIC) of the headset. According to the different installation positions of the microphones for collecting noise in the earphone, the microphones are divided into feedforward (FF for short) and Feedback (FB) noise reduction microphones, and the feedforward (FF) and the Feedback (FB) noise reduction microphones have different functions respectively. The feedback noise reduction microphone is closer to the diaphragm of the sound production unit 140, so that the feedback noise reduction microphone can be independently utilized to collect the sound emitted by the loudspeaker, and meanwhile, the feedback microphone can be used for collecting when the noise reduction amount is calculated because the position of the feedback microphone is near the sound outlet of the earphone.

As shown in fig. 3 and 4, the earphone housing 310 is opened with an anterior vent 130. The channel array 320 is disposed inside the front vent 130, and includes a plurality of sound channels 321 arranged in parallel, two ends of the plurality of sound channels 321 are open, a middle portion of the plurality of sound channels 321 is penetrated by a sound inlet 322, and the sound inlet 322 is aligned with the front vent 130, so that the front vent 130 can realize sound venting through the plurality of sound channels 321. In the present embodiment, the plurality of sound passages 321 are opened at both sides, and a dust screen 323 is further provided to prevent the sound passages 321 from being blocked.
As shown in fig. 3, the adjusting plug 330 extends into the sound inlet 322 and can move along the sound inlet 322 under the driving of the driving unit to block different numbers of sound channels 321, when the earphone is worn loosely, the adjusting plug 330 moves upwards to increase the number of sound channels 321 to be blocked, and when the earphone is worn tightly, the adjusting plug 330 moves downwards to decrease the number of sound channels 321 to improve the noise reduction effect of the earphone by controlling the sound leakage amount of the front sound outlet 130.
In the present embodiment, as shown in fig. 3, the driving unit includes: a magnet 340 fixedly connected with the adjusting plug 330, and an electromagnet 350 arranged opposite to the magnet 340, wherein the electromagnet 350 is fixed inside the earphone through a magnet bracket 360.

the wearing detection module 210 is specifically configured to: after the earphone is worn, the noise reduction microphone of the earphone is used for collecting preset low-frequency sound played by the earphone when the earphone measures frequency response, and the sound loudness in the current wearing state is calculated according to the collected sound. The frequency of the preset low-frequency sound is 20-100Hz, the wearing state is sensitive to low frequency, and the detection of the low-frequency sensitivity of the earphone can be well realized by collecting the preset low-frequency sound played by the earphone.
Correspondingly, in the leakage adjusting module 220, the sound channel 321 is set correspondingly according to a preset sound loudness gear, and the wearing detecting module 210 controls the adjusting plug 330 to move to a corresponding position of the sound inlet 322 according to the calculated sound loudness gear. In the present application, since the human ear 110 is insensitive to sounds within 3dB according to the hearing characteristics of the human ear 110, preset sound loudness steps are continuously distributed, and the width of each sound loudness step is set to 3 dB.
Referring to fig. 4, in one embodiment of the present application, the average loudness of the headphone at the correct amount of sound leakage is calculated to be 100dB, and then the four sound channels 321 are divided into five steps, i.e., five steps a, B, C, D, and E, in the channel array 320 shown in fig. 4, corresponding to the loudness ranges of a (94dB-97dB), B (97dB-100dB), C (100dB), D (100dB-103dB), and E (103dB-106dB), respectively. When the wearing state of the earphone is proper, the calculated sound loudness is 100dB, and the adjusting plug 330 is located at the standard gear c without noise reduction compensation; when the earphone is worn loosely, if the calculated sound loudness is lower than 100dB, the adjusting plug 330 is moved to the gear a or b according to the gear correspondence (for example, if the calculated sound loudness is in the gear a, the adjusting plug 330 is moved to the gear a), and the noise reduction effect is balanced by reducing the sound leakage amount of the front leakage hole 130; when the earphone is worn too tightly, the calculated sound loudness is higher than 100dB, and then the adjusting plug 330 is moved to the gear d or e according to the gear corresponding relation, so as to balance the noise reduction effect by improving the sound leakage amount of the front leakage hole 130.
Alternatively, in another embodiment of the present application, the wearing detection module 210 is specifically configured to: after the earphone is worn, the noise reduction microphone of the earphone is used for respectively collecting the ambient noise (1) of the earphone under the condition of closing the noise reduction function and the ambient noise (2) under the condition of opening the noise reduction function, and the noise reduction amount under the current wearing state is obtained by performing difference calculation (2) - (1).
Correspondingly, in the leakage adjusting module 220, the sound channel 321 is correspondingly set according to a preset noise reduction gear, and the wearing detecting module 210 controls the adjusting plug 330 to move to a corresponding position of the sound inlet 322 according to the calculated noise reduction gear. Preferably, the preset noise reduction gears are distributed continuously, and the width of each noise reduction gear is 2 dB. Similarly to the first manner, the noise reduction gear also includes a standard gear that is appropriate for wearing the headset and does not need compensation, a gear that improves the shielding degree of the front vent hole 130 when the headset is worn loosely, and a gear that reduces the shielding degree of the front vent hole 130 when the headset is worn tightly, which are not illustrated herein one by one.
Furthermore, in an embodiment of the present application, the noise reduction effect automatic adjusting apparatus further includes: and a prompt module. When the wearing detection module 210 determines that the degree of tightness of the earphone exceeds the adjustment range of the leakage adjustment module 220, the prompt module sends out prompt information to remind the user to wear the earphone again.
