1. An acoustic device, comprising:
one or more shells each of which includes an accommodation cavity and an opening;
one or more speakers each of which includes a vibration component and a vibration transmission plate; the vibration transmission plate is connected with the vibration component, wherein the vibration component is accommodated in the accommodation cavity; and
one or more protection components configured to prevent a foreign body from entering the accommodation cavity through the opening, wherein at least a portion of one of the one or more protection components is physically connected with the vibration component to transmit a vibration of the vibration component to the outside; wherein at least one of the one or more protection components includes a first portion and a second portion, the first portion and the second portion form an accommodation portion, at least a portion of the vibration component is arranged in the accommodation portion; the first portion is configured to seal one end of the accommodation portion, and the first portion fits and contacts the vibration transmission plate.
 
20. A method for preparing one or more protection components of an acoustic device, comprising:
forming a combination by fitting a mesh structure and a lining material, wherein a hardness of the lining material is greater than a hardness of the mesh structure;
obtaining a shaped combination by shaping the combination using a molding technique; and
obtaining, based on the shaped combination, the one or more protection components of the acoustic device including one or more shells each of which includes an accommodation cavity and an opening;
one or more speakers each of which includes a vibration component accommodated in the accommodation cavity; wherein the one or more protection components are configured to prevent a foreign body from entering the accommodation cavity through the opening, wherein at least a portion of one of the one or more protection components is physically connected with the vibration component to transmit a vibration of the vibration component to the outside.
