SU82882A1 - Electric musical instrument - Google Patents

Description

Electric musical instruments, in which the strings or metal strings are driven into a tweet, are transmitted. The direct movement of the keys and the induction of electrical oscillations in the pickups. Pickups can be connected in series or pa .i ,, -ie.-ibHo.

Usually such electrically-musical instruments have one lack that in e.1ectrix 1 () the iro production and d1 circuit always appear in. Both the operation and the operating system are impaired, and the system decelerates and the distortion occurs. timbre sound.

In the described musical instrument, this disadvantage is eliminated, that the operator, who is under the control, can be removed, and who can connect the contacts controlled by the keys in such a way that all pickups, when connected, are connected to the norm. -contacts and keys and a personal connection are connected to the socket with the normally open block contacts kl; ns From now on, to ensure a more consistent uniformity of the high and high frequencies, the pickups of different sensibility for different TOHOISs are used in the instrument.

FIG. I and 2 are shown, two options of instrumente; in fig. 3-printsial electrical circuit, odiakog.a dh both types of tools.

According to the first variant (Fig. 1), the tool is equipped with plates, possessing a single and a constant setting.

The yoke /, stamped from sheet zhe.cheza, bears on itself the winding 2 pickups n ilastina (measles) 1 of magnetized steel; the plate may fluctuate from impact but a hammer 4 keys o.

When vibrations are superimposed in the winding, 2 sound carriers are induced, y. d. s. e. d. s. electrical oscillations iodine on the wired, on the receiver, and after amplification on the loudspeaker.

FIG. Figure 2 shows the second embodiment of the instrument, OT; IKchchayuschiy from the first option, using instead of the oscillating plate 3, string 6, which requires a non-periodic tuning as shown in Fig. 3, all the windings of the 2 pickups are connected in series, and the two output ends of the final pickups are connected to a potentiometer 7 fixed on the axis of the moderator pedal.

To eliminate distortions and attenuation from broken windings of sound carriers, each of them is bypassed with contacts 8 fixed on the rear side of the avin1. Only those windings are included in the circuit with keys.

To ensure the natural reproduction of bass and treble sounds, sound pickups of different sensitivity for different tones are applied.

Claims (2)

1. An electric musical instrument in which the strings or plates are brought into oscillatory movement by key strokes and excite e; 1electric oscillations supplied to the amplifier and then converted by the loudspeaker to sound cocks, characterized in that none of the inoperative pickups, by preventing the electric vibrations generated by the working pickups from passing through them, all the pickups are normally shunted when they are connected in series A closed blokkontaktami keys, and the parallel-enabled village chedovatelno with normally open blokkontaktami keys. 2. In the electrical music instrument according to claim 1, use pickups of different sensitivity for different tones in order to ensure natural reproduction of the low and high frequency sounds. cXi
