Referring to fig. 4, when the first sound generating unit 2 is in a sound generating state, the shielding portion moves to a first position, so that the first passage 4 is in an open state, and the second passage 5 is in a closed state. For example, the sound generating action of the first sound generating unit 2 can be linked with the movement of the shielding portion, and the shielding portion can be moved to the first position when the first sound generating unit 2 generates sound.

When the shielding portion moves to the first position, the shielding portion may open the first passage 4, so that the first passage 4 is in an open state, and at this time, the closed state of the second passage 5 may be that the shielding portion closes the second passage 5 by the shielding portion while moving to the first position, or that the second passage 5 is already in a closed state before the shielding portion moves to the first position, and the second passage 5 may be opened only when the shielding portion moves to the second position, for example, the open/close state of the second passage 5 is controlled by a diaphragm having a gap.

In one embodiment, the first channel 4 may be in an open state when the first sound generating unit 2 is in a sound generating state, and in another embodiment, the first channel 4 may be in a closed state when the first sound generating unit 2 is in a non-sound generating state. When the first sounding unit 2 is in the sounding state, the opening of the first channel 4 may be to push the shielding portion to the first position according to the sound pressure airflow caused by the vibration of the diaphragm in the first sounding unit 2, and at this time, the shielding portion may open the first channel 4; the circuit board in the earphone can also control the movement of the shielding part according to the sound production state of the first sound production unit 2, so that the first channel 4 is opened when the shielding part moves to the first position.

Referring to fig. 2, when the second sounding unit 3 is in the sounding state, the shielding portion moves to the second position, so that the second channel 5 is in the open state, and the first channel 4 is in the closed state. For example, the sound generating action of the second sound generating unit 3 can be linked with the movement of the shielding portion, and the shielding portion can be moved to the second position when the second sound generating unit 3 generates sound.

In one embodiment, the second channel 5 may be in an open state when the second sounding unit 3 is in a sounding state, and in another embodiment, the second channel 5 may be in a closed state when the second sounding unit 3 is in a non-sounding state. And the opening of second passageway 5 when second sound production monomer 3 is in the vocal state can be according to the sound pressure air current that the vibration of vibrating diaphragm brought in the second sound production monomer 3 promotes shielding part to the second position, at this moment the shielding part alright with open second passageway 5, also can be the activity that circuit board in the earphone controlled the shielding part according to the vocal state of second sound production monomer 3 for shielding part activity is opened second passageway 5 when to the first position.

Optionally, the first sound generating unit 2 and the second sound generating unit 3 do not sound at the same time.

Specifically, the first sounding monomer 2 and the second sounding monomer 3 may have efficient sounding frequency bands respectively, for example, the first sounding monomer 2 may be an MEMS speaker with a good high-frequency sounding effect, and the second sounding monomer 3 may be a moving coil speaker with a good medium-low frequency sounding effect, so that the combination of the first sounding monomer 2 and the second sounding monomer 3 may give consideration to the sound effects of high, medium and low frequencies. Moreover, when different frequency bands are required to sound, the earphone can flexibly select the first sounding monomer 2 or the second sounding monomer 3 to sound, so that the first sounding monomer 2 and the second sounding monomer 3 can generate sound, and the sound effect of the earphone is guaranteed.

Optionally, referring to fig. 2, the first channel 4 includes a first through hole 41, the second channel 5 includes a second through hole 51, and the shielding portion includes a first shielding portion 42 engaged with the first through hole 41 and a second shielding portion 52 engaged with the second through hole 51;

That is, when the shielding portion moves to the second position, the second shielding portion 52 is away from the second through hole 51 and releases the seal of the second through hole 51, and the first shielding portion 42 is close to the first through hole 41 and forms a seal of the first through hole 41, so that the flexibility of the shielding portion in adjusting the opening and closing states of the first through hole 41 and the second through hole 51 is improved.

under the condition that the second sounding unit 3 is in the sounding state, the shielding portion moves to the second position, and the first magnetic member 411 and the second magnetic member 421 are magnetically attracted and connected.

Specifically, when the shielding portion moves to the second position, the first shielding portion 42 may be close to the first through hole 41 and seal the first through hole 41, and in order to improve the sealing effect of the first shielding portion 42 on the first through hole 41, the first shielding portion 42 may be tightly attached to the first through hole 41 and block the first through hole 41. The magnetic attraction between the first magnetic element 411 and the second magnetic element 421 can make the first shielding portion 42 tightly attached to the first through hole 41, so as to ensure the sealing property of the first passage 4 when the first shielding portion 42 is closed.

Similarly, when the shielding portion moves to the first position, the second shielding portion 52 may be close to the second through hole 51 and seal the second through hole 51, and in order to improve the sealing effect of the second shielding portion 52 on the second through hole 51, the second shielding portion 52 may be tightly attached to the second through hole 51 and seal the second through hole 51. And the magnetic attraction fit between the third magnetic element 511 and the fourth magnetic element 521 can make the second shielding portion 52 tightly attached to the second through hole 51, thereby ensuring the sealing property of the second channel 5 when the second shielding portion 52 is closed.

Specifically, the first magnetic member 411 is a first iron sheet, and the second magnetic member 421 is a first magnet, so that when the first iron sheet and the first magnet are close to each other, no matter which pole of the first magnet is close to the first iron sheet, magnetic attraction of the first iron sheet and the first magnet can be achieved, and the sealing performance when the first passage 4 is closed is ensured.
