An impact label for use as a baseball training aid includes a deformable layer and an incompressible layer which may include aluminum foil and paper, respectively. The incompressible layer includes voids distributed in a regular pattern. A first side of the incompressible layer is adhered to the deformable layer. A second side of the incompressible layer is formed around the barrel of a baseball bat, e.g., via an adhesive on a base layer. Areas of the deformable layer proximate to the voids and within an area of contact with a baseball during a swing of the bat are adapted to deform in response to contact with the baseball, thereby creating dimples that are indicative of the area of contact and force of contact.

The present disclosure provides a diaphragm and a sound generating device using the diaphragm. The diaphragm comprises a diaphragm body part, and a composite layer bonded to the center of the diaphragm body part. The composite layer comprises: a porous material layer; and a first metal layer and a second metal layer respectively disposed on two sides of the porous material layer. Compared with the prior art, the composite layer of the diaphragm adopts a composite structure composed of a porous material layer and metal layers, which can reduce the mass of the diaphragm and improve the modulus density ratio of the diaphragm while ensuring the rigidity of vibration. The porous structural material can increase the damping of the diaphragm, absorb the vibration energy under the specific resonant frequency, and thus effectively improve the high-frequency split vibration, reduce the distortion and improve the high pitched sound quality.
