specific Embodiment approach 1
[0023] Specific implementation mode one: combine Figure 1 to Figure 7 Describe this embodiment, this embodiment includes a frame body 1 and two cover bodies 2, the two cover bodies 2 are arranged oppositely, and the two cover bodies 2 are connected through the frame body 1, and each cover body 2 includes a suspension bracket 2-1 and the graphene film 2-2, the suspension bracket 2-1 is a bowl-shaped grid frame, and the graphene film 2-2 is attached to the suspension bracket 2-1.
specific Embodiment approach 2
[0024] Specific implementation mode two: combination figure 2 To describe this embodiment, the graphene thin film 2-2 of this embodiment has a thickness of 3-4 nm. Such a setting makes it easy to transmit the sound through the soft graphene film without loss. Other compositions and connections are the same as in the first embodiment.
specific Embodiment approach 3
[0025] Specific implementation mode three: combination figure 2 To illustrate this embodiment, the number of graphene layers covered by this embodiment is 1-12 layers, and the thickness is limited to 0.1-4nm. In this way, the single-layer graphene is far more than other thin film materials, and its thickness of 3.4nm is the minimum value of the material thickness, which leads to a very low out-of-plane bending stiffness of the material. In addition, the material density per unit area of graphene is very low. If the sound pressure is not enough to cause the graphene film to expand and stretch, the sound wave can pass through the soft graphene film almost without damage. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.
[0026] Specific implementation mode four: combination Figure 3 to Figure 5 To describe this embodiment, the shape of the mesh of the bowl-shaped grid frame in this embodiment is triangular, quadrangular, circular, h...
