INVENTOR. "|RW|N F. HYDEN ATTORNEYS United States Patent 3,126,436 BRASS VOICE FORMANT SYSTEM FOR ELECTRONIC ORGAN Irwin F. Hyden, 408 Trenton Road, Norman, Okla. Filed Aug. 28, 1961, Ser. No. 134,398 2 Claims. (Cl. 841.01)
This invention relates to electronic musical instruments and more panticularly, but not necessarily by way of limitation, relates to voicing or tone formant means for producing realistic brass musical effects for an electronic organ.
As is Well known in the art, organ music has experienced a very rapid rise in popularity during the last few decades. This greatly increased popularity of organ music is primarily attributable to the so called orchestral type electronic organ which is capable of producing a multitude of voices or tones simulating the various instruments of an orchestra. These voices add color and versatility to the more conventional types of organs and permits the artist to play almost all types of musical compositions, including the more contemporary popular melodies. As is known, the orchestral type organ is capable of producing with considerable aesthetic quality the sounds or voices of the flutes, reeds, chimes, and stringed instruments entirely by electronic wave shaping means. This production of various sound simulations is in general referred to in the art as voicing and is accomplished by so-called formant circuits or systems. However, within my knowledge, the production of a brass voice having outstanding aesthetic quality has not heretofore been accomplished in the electronic organ art. Although the wave shapes of the brass instrument audio signals can be fairly closely approximated by electronic wave shaping or formant circuits, the resulting audio sound generated by a conventional loudspeaker, which is used for all other voices of the organ, is not sufliciently authentic to be acceptable from an aesthetic standpoint.
Therefore, it is an important object of the present invention to provide a voice formant system in an electronic organ for producing a brass voice effect which simulates a brass musical instrument and which is of sufficient quality to be aesthetically acceptable to the performing artist and to those appreciating high quality organ music.
The present invention accomplishes this high objective by providing an audio driver which is driven by an electrical signal which has been shaped by any suit-able organ electronic formant circuit to simulate the frequency and tone content of a brass horn audio signal. The audio driver is coupled to a suitable brass musical instrument, such as the conventional bugle, to introduce the audio signal to the instrument in the same manner that an audio signal is introduced by the lips and wind of a person playing the instrument. The resulting brass voice is aesthetically acceptable as a simulation of a brass instrument and has a particularly striking effect when played as a solo or single note type melody with accompaniment from the other voices of an orchestral organ. The strikingly authentic efiect is believed to be the result of mating the electronic formant circuit within the organ which produces through the audio driver a mechanical effect corresponding to the lips and wind of an artist playing the brass instrument and the ability of the brass type musical instrument to mechanically form or shape the sound produced therethrough and produce the final brass simulation.
Additional objects and advantages will be evident from the following detailed description and drawings wherein:
FIGURE 1 is a diagram of a combination electronic 3,126,436 Patented Mar. 24, 1964 iceand mechanical voice formant system in accordance with the present invention.
FIGURE 2 is a cross-sectional view of a part of the device of FIG. 1.
Referring now to FIG. 1, a power supply 10 is connected to drive a bank of tone generators consisting of oscillators, dividers or the equivalent represented by the block 12. The bank of oscillators 12 may be of any suitable conventional design as presently used in electronic organs which usually comprises a separate oscillator device for each note of the musical scale to be produced. The outputs from the oscillators are usually pure sine Waves and are selectively controlled by a conventional organ keyboard 14 in a conventional manner. When pressed, each key of the keyboard 14 selectively connects the output signal from the corresponding note oscillator to a desired formant circuit, which in the present case is the brass formant circuit 16. Although the diagram illustrates the type of organ which is operated by keying the output from the oscillators, it is to be understood that other conventional types of organs, such as those which utilize a key system between the power supply and the oscillators, may also be employed. It is also to be understood that the oscillators 12 are connected to the brass formant circuit 16 by the appropriate stop tab switch in the conventional manner known in the organ art. The generated wave signal is shaped by the formant circuit 16 to produce a signal corresponding in frequency content or shape (resulting from the necessary harmonics) to that of an audio sound produced by a brass instrument. In other words, the signal from the brass formant circuit 16 has a primary frequency and harmonic content corresponding as closely as is electronically possible to duplicate that of an audio signal from a brass instrument. The output from the brass formant circuit 16 is fed to an amplifier 20 where the signal is amplified and fed to a small diaphragm audio driver 22.
The audio driver 22 is shown in detail in the crosssectional view of FIG. 2 and comprises a case 24 which houses a magnet 26. The magnet 26 is supported in fixed position within the housing 24 by any suitable means (not shown). A diaphragm 28 is supported within the case 24 in a conventional manner by an annular flexible portion 28a which permits the diaphragm 28 to oscillate. A coil 30 is connected to the diaphragm 23 and is disposed within the magnet 26 and surrounds the core 32. The coil 30 is connected to receive the electrical signal from the amplifier 2i), and when the signal is passed through the coil, the diaphragm is oscillated in the conventional manner to produce an audio signal. The face of the diaphragm 28 is directed towards an audio output sleeve 34 which is threaded into an adaptor sleeve coupling 36-. The adaptor sleeve coupling 36 corresponds very closely to the mouthpiece of a conventional brass instrument except that it is threaded internally for receiving the threaded portion of the audio output sleeve 34. The adaptor 36 is then received in the first end 38 of a conventional brass musical instrument of a type which it is desired to most closely simulate. The brass musical instrument which has been found to produce a very satisfactory result is the conventional bugle (FIG. 1), which has a proportionately long first portion of substantially constant diameter, which is represented by the coiled portion 38a, and a short bell flare 38b at the second end thereof.
In operation, the electronic organ functions in the conventional manner when played by an artist. When the brass stop is pressed, the generated wave signals from the oscillator bank 12 are fed, when the corresponding key on keyboard 14 is pressed, to the brass formant circuit 16. The waves are shaped or formed by the 3 formant circuit 16 to contain the various harmonics of the sounds of brass musical instruments. The shaped brass signals are then amplified by amplifier 20 and applied to the audio driver 22 which produces an audio signal havingv aharmonic content substantially like that of the shaped electrical signal from the formant circuit. The audio signal produced by the audio driver is then mechanically modified by the brass instrument to produce the final brass voice.
'From the above detailed description, it will be evident that a novel voice formant system has been described for producing an acceptable brass voice by the combination of electronic and mechanical formant components. Experimentation has revealed that the combination of mechanical parts comprising the diaphragm audio driver and the brass horn is useful in providing unique and aesthetic voices when used incombination with electronic formant circuits which normally produce reed and string voice simulations, although its principal and most authentic use is in combination with the brass formant circuitry. Therefore, it is to be understood that various changes can be made in the components of the combination without departing from the spirit and scope of my invention as defined by the appended claims.
