Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of artificial larynx, and particularly relates to a pneumatic artificial larynx speech device. Background Art
[0002] An artificial larynx, also known as a speech aid, is a device artificially manufactured to act as a sound source and vibration source to emit a sound similar to that of a human. When the larynx is removed and the ability to speak is lost, it can be used as a tool for auxiliary speaking. Artificial larynxes can be basically divided into three types: mechanical artificial larynx; electronic artificial larynx; implanted artificial larynx.
[0003] A mechanical artificial larynx is also called a pneumatic artificial larynx. A pneumatic artificial larynx generally includes a sound guide tube, a vibration assembly, and a cup. The vibration assembly is provided with a nozzle connected to the sound guide tube. When using a pneumatic artificial larynx, one end of the sound guide tube close to the nozzle needs to be bent, causing stress concentration at the bent part of the sound guide tube. When the sound guide tube is frequently bent, the sharp corners of the nozzle will damage the inner wall of the sound guide tube, reducing the service life of the sound guide tube. At the same time, the inner wall of the sound guide tube is scratched by the sharp corners, resulting in the shedding of plastic particles. The shed plastic particles will damage human health after entering the human body. Summary of the Invention
