Optionally, the through holes include a first through hole 201 provided in the first magnetic circuit system. It can be understood that the first magnetic circuit system is generally opposite to the first diaphragm 21, that is, the first through hole 201 is opposite to the first diaphragm 21, so that the sound wave generated by the vibration of the first diaphragm 21 can be directly transmitted to the corresponding first sound outlet 11 through the first through hole 201, and the transmission efficiency of the sound wave is higher.
Alternatively, the first magnetic circuit system includes a central magnetic circuit portion 23 and a side magnetic circuit portion 24, at least one of the central magnetic circuit portion 23 and the side magnetic circuit portion 24 is provided with a permanent magnet, and the magnetic gap 20 of the first magnetic circuit system is formed between the central magnetic circuit portion 23 and the side magnetic circuit portion 24, in which case the first voice coil 22 is generally disposed around the central magnetic circuit portion 23.

Alternatively, the side magnetic circuit portion 24 may also be provided with the first through hole 201; indeed, the first through hole 201 of the side magnetic circuit portion 24 also facilitates the transmission of the sound waves in antiphase to the corresponding first sound outlet 11 and then to the outside of said casing 1.
Optionally, the first magnetic circuit system may further be provided with a first through hole 201 communicating with the magnetic gap 20 thereof; indeed, the first through hole 201 of the side magnetic circuit portion 24 is also beneficial to transmitting the opposite-phase sound wave to the corresponding first sound outlet 11, and then to the outside of the housing 1; in particular, the first through hole 201 communicating with the magnetic gap 20 of the first magnetic circuit system needs to penetrate through a relatively short physical thickness, which is beneficial to the opening of the first through hole 201. Further alternatively, the first through holes 201 communicating with the magnetic gap 20 of the first magnetic circuit system are generally provided in plural, and the plural first through holes 201 are provided at intervals along the magnetic gap 20 to increase the passing area of the anti-phase acoustic wave.
