Description

Speech instrument

technical field

The invention relates to a sound-generating device specially used for disabled persons with laryngeal areas, in particular to an artificial laryngeal talking device capable of restoring speech to disabled persons with laryngeal areas.

Background technique

There are four steps in people's pronunciation: sound production, vibration, resonance and improvement and expansion of pronunciation. Sound production is due to the movement of lung expiratory airflow, vibration is the basic sound produced by the vibration of the vocal cords of the larynx, resonance is the expansion of the sound of the pharynx, oral cavity, and nasal cavity above the larynx, and the expansion of sound is the basis for the reconstruction and expansion of the tongue, teeth, lips, and palate sound, and become a recognizable sound. The larynx is the main organ for pronunciation. Due to tumor invasion, surgery to remove the larynx is required, and the patient becomes disabled without laryngeal aphonia. In order to help patients recover their pronunciation function, language reconstruction is currently performed on patients through artificial and mechanical means.

Artificial instruments, usually also called speech aids and artificial larynx, place one end of the artificial laryngeal catheter at the tracheostomy opening in the neck and the other end at the front of the mouth when the patient speaks, and use the exhaled airflow in the lungs to enter the machine. The vibration chamber of the larynx causes the rubber membrane to vibrate to produce the basic sound, and then forms speech through the language formation organs. Artificial Larynx, also known as a speech instrument, is an artificially manufactured device that acts as a sound source and vibrates to produce a voice similar to that of a human being. When the larynx has been removed and the ability to produce sounds is lost, it can be used as a tool to assist in speaking. Present artificial larynx can basically be divided into three kinds: mechanical artificial larynx; Electronic artificial larynx; Implantable artificial larynx.

Mechanical artificial throat, also known as pneumatic artificial throat, such as the patent application number CN91222403.7 discloses a mechanical artificial throat, including sounding tube, gas nozzle, diaphragm and conduit, an air nozzle is installed in the inner cavity of the sounding tube, The gas nozzle has an air inlet and an air outlet, a diaphragm is arranged outside the air outlet, and the air inlet communicates with the conduit. When in use, the sounding tube can be placed against the throat, and the catheter can be placed in the oral cavity to pronounce. Speaking with the mechanical artificial larynx will cause saliva to condense in the catheter and be easily inhaled into the lungs.

Electronic artificial larynx, referred to as electronic larynx, discloses a kind of electronic artificial larynx as the patent of application number CN86204344, is made of electronic oscillation amplifying circuit, transducing sound generator, battery, cylinder body. The pulse signal generated by the electronic oscillating amplifier circuit is converted into an audio signal by the transducer sounder, so that the transducer sounder emits a sound with a frequency of 128-1024Hz. Due to the sound generated by the electric machinery, the speech is like a robot, with a high distortion rate.

The patent application number 02135031.0 discloses an implantable artificial larynx, which includes an epiglottis body and a laryngeal body. Because the nickel-titanium shape memory alloy is used as the skeleton material of the epiglottis, it ensures that the epiglottis has good elasticity, which is conducive to opening and closing. At the same time, the throat adopts a double-layer structure, and the outer layer is convenient for granulation to penetrate and grow, which can fix the throat. The role of the inner layer is to effectively block the excessive growth of granulation and prevent throat stenosis. The artificial larynx needs to be re-operated by the hospital's experts on those who have no larynx. The disadvantage is that the cost is high, and only a few hospitals in China can operate it.

To sum up, existing speaker devices generally have problems such as complex structure, high cost, inconvenient use, and poor sound effects.
