Stuttering brings a lot of troubles to patients. We designed a circuit to
correct stuttering patients, and it has been used by several patients with different degrees of stuttering, and has achieved certain
effects.
The stuttering correction circuit is shown in the figure. A self-excited multivibrator is composed of NE555, island, C2,
RP1 and other components
. The parameters of Rz, RP1 and bar are appropriately selected to make the circuit work within the ultra-low frequency range. When S2 reaches the I
block, the light-emitting diode I. ED lights up according to the number of beats; when S2 is in the II
position, the earphones produce a "beat, beat" sound. Adjusting RP2 can change
the number of beats. It can be applied to patients with different degrees of stuttering; adjusting RP2 can also change the volume of the headphones to make the patient feel comfortable and cooperate
with treatment.
After repeated corrections many times, stuttering patients can gradually recover.
