Elastic Sound Generating Device

Abstract

An elastic sound generating device, comprising an elastic sounding body integrally formed of an elastic material, the elastic sounding body having therein one or more sound amplified holes which can be pressed to adhere and then released to generate vibration and sound, and the sound amplified hole is opened through an outer surface of the elastic sounding body. The elastic sounding body is pressed and deformed until inner walls of the sound amplified hole adhere to each other, and then the elastic sounding body is released to restore the original shape and separate the inners wall of the sound amplified hole, and when the inner walls of the sound amplified hole are separated from each other, a sound is generated. The generated sound as a detectable signal is a solution for the range of motion of the training joint, the strength of the output and the shortest duration.
