のは価格が高くなる難がある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker diaphragm, and this type of research has been progressing recently. It is known that the diaphragm of a speaker is made of a material with high density and strength, has a faster sound propagation speed, and generates high-quality high-pitched sounds. However, products that require complex technology have the disadvantage of being expensive.

ば、均一な葉脈のある植物の葉に類似した構造である。The speaker diaphragm (1) of the present invention has a structure in which a part of the material is raised from the plate surface to form a uniform mesh-shaped protrusion (2) like the veins of a plant. According to the authors, the structure is similar to that of a plant leaf with uniform veins.

い。This diaphragm (1) is made of a thin diaphragm (1) by covering the surface of the diaphragm (1) with the leaf-like mesh-shaped protrusions (2).
becomes moderately rigid. As a result, the vibration rate and sound propagation speed are increased to the same or higher than that of the diaphragm (1) made of a harder material. Therefore, the amplitude decreases and
The frequency of vibration increases, the speed of sound propagation is faster, and it is possible to generate high-quality high-pitched sounds. Also, this mesh-shaped protrusion (2) part is the diaphragm (1)
There is no disturbance in the sound because it is on the back side and is moderately delicate.

Or, mix a small amount of alcohol with ceramic powder and use a high-precision mold to press and mold it.
Sinter at around 600 degrees. Synthetic resin diaphragms can be easily manufactured using excellent molding machines available at present. The features of this diaphragm are high-quality high-pitched sound generation and a low product price.
