As shown in fig. 1, according to an embodiment of the present invention, a part of the structure of the electroacoustic module 120 is in contact with the damping layer 111. Accordingly, vibration generated in the electroacoustic module 120 can be transmitted to the vibration damping layer 111 through the contact portion, and further, vibration can be absorbed by the vibration damping layer 111, thereby reducing noise and improving the vibration damping effect of the vibration damping layer 111.

Further, a portion of the electroacoustic component 120 in contact with the vibration damping layer 111 is interference-fitted with the vibration damping layer 111. It can be understood that, electroacoustic component 120 can be through interference fit and damping layer 111 in close contact with, on the one hand can promote the convenience of vibration transmission, promotes the damping effect of damping layer 111, and on the other hand, can also utilize interference fit to promote the installation stability of electroacoustic component 120 in box body 110, avoids electroacoustic component 120 to appear rocking in box body 110.

In order to further improve the vibration damping effect of the vibration damping layer 111 and reduce the probability of resonance of the electro-acoustic device 100, in some embodiments, the minimum distance between the electro-acoustic assembly 120 and the inner surface of the case 110 is greater than or equal to 2 mm. It should be noted that, in order to reduce the vibration of the electroacoustic device 100, the electroacoustic component 120 and the case 110 may be spaced apart by the vibration damping layer 111. To further reduce the vibration of the electro-acoustic device 100, the minimum distance between the electro-acoustic assembly 120 and the inner surface of the case 110 is 2mm or more.

In some embodiments, the damping layer 111 may be a sponge layer, a silicone layer, or a foam layer. Further, when the vibration damping layer 111 is a sponge layer, the sponge layer may be a foamed sponge. The density of the foaming sponge can be 13-50kg/m³。

Therefore, the mounting opening 112 can be closed by the cover 115, so that the electroacoustic component 120 located inside the main body 113 can be protected, and the vibration damping effect of the cartridge 110 can be improved. Additionally, in some embodiments, one of the cover 115 and the body 113 may have an acoustically transparent aperture disposed therein.

As shown in fig. 2, in some embodiments, the surface of the cover 115 facing the inside of the mounting cavity 114 and the inner surface of the main body 113 are both provided with a vibration damping layer 111.
