The first diaphragm 32 moves relative to the second diaphragm 33 in a direction away from the second diaphragm 33, and the movement of the first diaphragm 32 increases the volume of the first rear cavity 34 between the first diaphragm 32 and the second diaphragm 33, and decreases the volume of the first front cavity 40 formed by enclosing the first diaphragm 32, the screen 20, the frame 10, and the housing 31, which can be understood that the movement of the first diaphragm 32 changes the volume of the first rear cavity 34 and the volume of the first front cavity 40.

In the embodiment of the present application, the electronic device 100 is provided with the first sound outlet 50 and the second sound outlet 12, and the first sound outlet 50 and the second sound outlet 12 are used for sound.

In these alternative embodiments, the sealing between the first front cavity 40, the second front cavity 60 and other internal cavities in the electronic device 100 is achieved by the first seal member 70 and the second seal member 80, and the first seal member 70 is located between the first housing 311 and the stopper 11, so that the first seal member 70 is disposed near the first diaphragm 32, and the second seal member 80 is located between the end surface of the second housing 312 and the frame 10, so that the second seal member 80 is disposed near the second diaphragm 33, and therefore, the first diaphragm 32 and the second diaphragm 33 can be damped.
In some alternative embodiments, when the acoustic assembly 30 is operated in the speaker mode and the acoustic assembly 30 is in the second volume scene, the first sound wave formed by the vibration of the first diaphragm 32 and the second sound wave formed by the vibration of the second diaphragm 33 have the same phase, and the volume of the second volume scene is greater than the volume of the first volume scene.
Specifically, the acoustic assembly 30 includes two acoustic waves, such as a first acoustic wave from the sound wave generated by the vibration of the first diaphragm 32 and a second acoustic wave from the sound wave generated by the vibration of the second diaphragm 33. The first diaphragm 32 vibrates and forms a first sound wave that passes out of the first sound outlet 50 through the first front cavity 40. The second diaphragm 33 vibrates and forms a second sound wave that is transmitted out of the second sound outlet 12 through the second front chamber 60. The first sound wave and the second sound wave are identical in phase and are mutually overlapped, so that a second volume scene, namely a high-pitch scene, is realized in a loudspeaker mode. The second diaphragm 33 vibrates and forms a second sound wave, which is transmitted from the second sound outlet 12 through the second front cavity 60, and the first diaphragm 32 does not vibrate, and at this time, only the second sound wave sounds, so that in the speaker mode, a first volume scene, that is, a mid-bass scene, is realized, and therefore, the volume of the second volume scene is greater than that of the first volume scene.
In these alternative embodiments, when the acoustic assembly 30 is operated in the speaker mode and the acoustic assembly 30 is in the second volume scene, the first sound wave formed by the vibration of the first diaphragm 32 and the second sound wave formed by the vibration of the second diaphragm 33 have the same phase, and the first sound wave and the second sound wave having the same phase are overlapped with each other, so that the volume is enhanced, and therefore, the volume of the second volume scene is greater than that of the first volume scene.
In some alternative embodiments, the first sound wave formed by the vibration of the first diaphragm 32 and the second sound wave formed by the vibration of the second diaphragm 33 are opposite in phase when the acoustic assembly 30 is operated in the receiver mode.
Specifically, the acoustic assembly 30 includes two acoustic waves, such as a first acoustic wave from the sound wave generated by the vibration of the first diaphragm 32 and a second acoustic wave from the sound wave generated by the vibration of the second diaphragm 33. The first diaphragm 32 vibrates and forms a first sound wave that passes out of the first sound outlet 50 through the first front cavity 40. The second diaphragm 33 vibrates and forms a second sound wave that is transmitted out of the second sound outlet 12 through the second front chamber 60. Under the condition that the acoustic assembly 30 works in the receiver mode, the first sound wave formed by the vibration of the first vibrating diaphragm 32 and the second sound wave formed by the vibration of the second vibrating diaphragm 33 are opposite in phase, so that the first sound wave and the second sound wave cancel each other, the sound is in short circuit, the volume output by the acoustic assembly 30 is small, the sound which is answered by a user in a short distance is enabled, conversation contents are not easy to be heard by other persons in a long distance, the problem of sound leakage is solved, and conversation privacy is further well protected.
