Abstract
The utility model discloses an electronic artificial larynx used by a persons with a hurt larynx, comprising an electronic oscillation magnifying circuit, an energy transforming sonification device, batteries and a cylinder body. Pulse signals generated by the electronic oscillation magnifying circuit are transformed into audio signals by the energy transforming sonification device which sent out sounds with a frequency of 128 to 1024Hz. The electronic artificial larynx has the advantages of few noises, clear sonification, compact structure, small size with a height of only 12.5 cm, light weight of only 185 g, convenient portability and low cost. The utility model is more suitable for a person with hurt larynx to generate sounds and speak, and to restore the ability to work, live and communicate.
Description
This utility model is a kind of teaching aided machine that speak to use for larynx the disabled, is bionical voice,artificial official.
Artificial electronic larynx is to utilize the electronic line design to form.At present, all there are artificial electronic larynx production in the U.S., West Germany, but through China's without-throat person use that some exists that pronunciation is clear inadequately, volume more greatly, heavier, problem of ultra-high price.
Task of the present utility model provide a kind of pronounce clear, noise is few, volume is little, the improved technical scheme of artificial electronic larynx in light weight, that cost is low.
This technical scheme is by the electronic amplifying circuit.Transducing tone generator, power supply, cylindrical shell constitute.The pulse signal that is produced by the electronic amplifying circuit, convert audio signal to through the transducing tone generator, make the transducing tone generator send the sound of certain frequency, user is close to the transducing tone generator on the best acoustic point of neck top skin, can pronounce to speak through exercise.
Elaborate below by accompanying drawing:
Accompanying drawing 1 is the elevation cross-sectional view of artificial electronic larynx;
Accompanying drawing 2 is the left view and the part sectioned view of artificial electronic larynx;
Accompanying drawing 3 is electronic amplifying circuit figure.
Artificial electronic larynx transducing tone generator is made of tibial membrane (1), coil bump rod (4), magnetic head (6).Tibial membrane (1) is for having the plastics disk of holddown groove, and thickness is between 1 to 2 millimeter, and the centre does not have outstanding rum point, and is fixing by loam cake (2), during bump, pronounces distinctly.Magnetic head (6) is a cylinder, in the cannelure of one 0.6 to 0.8 mm wide is arranged, be fixed in the top cylinder (7).Coil bump rod (4) is made of electric coil (18), insulating support (17) and bump caput (16), is enclosed between the ring shaped slot of sheet rubber (3), barrel (5) and magnetic head (6).The electronic amplifying circuit, its low-frequency oscillation part is by BC
1, BG
2=P low-frequency transistor is formed, and its impulse wave passes through BG
3Power amplification is after transducing tone generator coil (18), magnetic head (6) transducing, coil bump rod (4) is just made up-down vibration with identical frequency of oscillation, and bump caput (16) clashes into tibial membrane (1) and sends frequency adjustable and be formed on sound between the 128-1024Hz.Its frequency is by the potentiometer R of its value at 30-50K Ω
1, promptly audio frequency is regulated knob (13) adjusting, and its volume is by the potentiometer R of its value at 10-30 Ω
2Be that volume is regulated knob (8) adjusting.Circuit panel (9), volume are regulated knob (8), frequency adjustment knob (13), switching circuit plate (15) and switch button (14) and are fixed on together in doffing (10) top.Battery (11) is placed in the doffing (10) between clothing lid (12) its circuit panel (9), and battery (11) is 5 volts of rechargeable batteries of direct current.Its circuit panel (9) of switching circuit plate (15) adopts laminated type to be fixed together compact conformation.
Artificial electronic larynx with above-described technical scheme manufacturing, noise is little, pronounce distinctly, compact conformation, volume is little, highly only have 12.5 centimeters, in light weight, only have 185 grams, easy to carry, cost is low, be more suitable for larynx the disabled and wear, can enough pronounce, talk, recover its work, life, sociability.
Claims (5)
1, a kind of artificial electronic larynx, form by transducing tone generator, electronic amplifying circuit, power supply, cylindrical shell, it is characterized in that the transducing tone generator, the band holddown groove is arranged, middle do not have the circular tibial membrane of plastics of outstanding rum point and a magnetic head of high conversion efficiency, the oscillator-amplification circuit of forming by the good transistor of low frequency amplification performance.
2, artificial electronic larynx according to claim 1 is characterized in that switching circuit plate (15) is welded on the control circuit board (9) with laminated type.
