Abstract

The vibrating piece (1) includes a vibrating member (10) having a first region and a second region formed integrally with each other using an isotropic material, and the first region has a Young's modulus ratio The reinforced part (13a-13d) of the second region part is high, and the reinforced part (13a-13d) is obtained by press forming with stronger pressure applied to the first region part than the second region part.

Description

technical field [0001] The invention relates to loudspeakers and sound systems. [0002] Background technique [0003] Since materials such as paper, plastic, and metal can be processed at a relatively low price and are easy to process, they are widely used as vibrating plate materials for audio equipment. However, since the transmission speed of vibration and sound is equal in all directions with these materials, standing waves are likely to be generated when a vibrating plate is manufactured, and various adverse effects may be exerted on acoustic characteristics. [0004] As a vibrating piece that suppresses the generation of standing waves, a wooden conical vibrating piece is disclosed in which wood whose propagation speed is different in the fiber direction and the non-fiber direction is used as the material of the vibrating piece. There is also disclosed an eccentric conical vibrating piece whose cross-sectional shape is asymmetrical by shifting the position of the voi...
