Muscular voltage-controlled tone-modifying device
US 3704339 A
Abstract
An electronic musical instrument is controlled also by the muscular voltage of the instrument player. A pair of electrodes are mounted on any selected portion of the skin of the player in order to pick up a muscular voltage appearing across a muscle upon a contraction thereof. The picked-up voltage is amplified and processed into a control signal which in turn controls the tone signal modifying circuit in the instrument. While the player is engaged in the ordinary performance using hands and feet, further effect control can be carried out at the player's will.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, there is illustrated an electronic musical. instrument such as a key-actuated electronic organ generally indicated at l which comprises as its playing actuatorsmanual keyboards 2 and 3 arranged in multiple stages, a pedal keyboard 4, an expression pedal 5, etc. A pair of electrodes 6a and 6b electrically associated with a grounded electrode are adapted to be securely mounted on the body of the player at appropriate positions of an arm 6 of the player, for example, on the skin surface on the inside of the forearm, by

means of an electrically conductive paste or an electrically conductive bonding tape, so that a muscular voltage produced upon contraction of a muscle of the arm and appearing at the skin on which the electrodes are mounted may be picked up.

The electrodes 6a and 6b are also connected with both ends of a primary winding L of a transformer L, while the secondary winding I thereof is connected to an input side of an amplifier circuit A; of which the output is connected through a rectifier circuit D to a terminal t.

Thus, the block E constitutes a muscular voltage processing circuit including said transformer L, said amplifier A said rectifier D and the terminal t. The picked-up muscular voltage which is generated upon contraction of the electrode-loaded muscle is amplified and rectified, thus developing a DC output signal depending on the muscular voltage at the terminal t.

Referring now to FIG. 2, there is shown an embodiment of muscular voltage-controlled tone modifying circuits (see, e.g., Journal of the Audio Engineering Society, vol. 13, No. 3, July, 1965, pages 200-206) such as a vibrato effect imparting circuit, atone coloring circuit and a tremolo effect imparting circuit of the instrument which are adapted to receive at its input the DC output signal developed at the output of the circuit E as a control signal, whereby either a tone signal in the instrument or the control circuit for controlling a tone signal-modifying circuit is subjected to the control by its electrical characteristics such as amplitude, frequency and phase to thereby vary the tone volume, the tone pitch, the tone color or other tonal effects in the instrument.

Symbol 0 represents tone source circuits which correspond in number to that of keys-arranged in the instrument. Individual tone signals generated by a number of said tonesource circuits are keyed by respective key-operated keying circuits: K and then the keyed tone signals are entered to tone coloring circuits F having filters therein. The output signals of the tone coloring circuits are applied to an amplifier circuit A and therefrom to the electro-acoustic transducer such as a speaker S.,To the tone source circuits 0 is also connected a vibrato effect-producing circuit V, i.e., a very low frequency oscillator, whereby individual oscillation frequencies at the oscillators of the tone source circuits 0 are varied to provide vibrato effects. Between the tone coloring circuits and the amplifier circuit A are provided tremolo effect producing circuit M which effects amplitude modulation of the input tone signals to produce tremolo effects. Thus, a circuit G including the above-mentioned circuits constitutes a conventional electronic musical instrument circuit. However, to the respective control terminals of these tone signal modifying circuits are connected output terminals of corresponding muscular voltage processing circuits E E E, which are similar to that E shown in FIG. 1, of which the inputs may be provided from muscular voltage pickup means mounted on biceps 6 extensor digitiformcommunis 6,, trapezius 7, sternocleidomastoid 8, vastus lateralis and vastus medials 9, and biceps of the thigh 9, in the muscular system of man, as shown in FIGS. 3A and 3B, in the same manner as that described in connection with FIG. 1.

DC signals at terminals t t t,,, whose levels depend on the magnitude of the picked-up muscular voltages, i.e., the amount of contraction of the above-mentioned muscles, act to vary the oscillation frequency or oscillation output level of the vibrato effect-producing circuit V, to vary the frequency characteristic of the filter in each tone coloring circuit F and also to vary the degree of amplification of the amplifier circuit A, respectively. For example, the muscular voltage processing circuit E, may be arranged to receive a muscular voltage which is picked up by the .muscular' voltage pickup means, i.e., electrodes, which are mounted on the biceps 6 or the extensor digitiform communis 6 upon extension or bending of the arm or the fingers, as a waveform shown in FIG. 6A, and to amplify and rectify it to produce a pulsating DC waveform shown in FIG. 6D whose levels depend on the degree of contraction of the muscles 6, and 6 while the amplifier A may be arranged to have a variable impedance element such as a gate-controlled field effect transistor for variably controlling its output level so as to vary the output volume of the speaker S in accordance with the degree of said extension or bending of muscle by application of said pulsating DC voltage to the gate of the transistor. Accordingly, the impedance of the variable impedance element can be increased or decreased in accordance with the degree of contraction of muscle, and hence, the same effect as that produced by the conventional expressionpedal .type instrument may be obtained, for example, by bending the arm or fingers having pickup meansmounted thereon or by applying a force thereto. Instead, the pickup means may be mounted on the trapezius 7 or the bicepsof a thigh 9 to pick up the muscular voltages, where the output volume of the instrument may be adjusted by an up and down motion of the shoulder or the leg. The greater the amount of contraction of muscle or the force applied thereto is, the greater will be the magnitude of the muscular voltage generated, whereas the smaller the amount of contraction or force is, the less will be the magnitude of the muscular voltage produced. Thus, the muscular voltage generally may be said to increase or decrease in accordance with the magnitude of extension or bending of arm or fingers. The muscular voltage, however, can be increased or decreased only by applying a force to the muscle.

Each of the tremolo effect producing circuit M, the vibrato effect producing circuit V and the tone coloring circuit F can be controlled also analogously by the use of muscular voltage generated depending on the degree of contraction of muscles in such a manner as has been described in connection with the control of the amplifier A.

The oscillation frequency at the tremolo frequency oscillator'circuit or the vibrato oscillator circuit may be changed accordance with'the degree of the muscular contraction, by varying the resistance component of a bias circuit or a CR coupling circuit which is used in said oscillator circuit using the above-mentioned variable impedance element.

As shown in FIG. 4, an electromagnetically actuated stop tablet J of the instrument may be controlled by a square pulse signal shown in FIG. 6B at the output of a monostable multivibrator H to the input of which the output signal of the muscular voltage processing circuit E, (E E,,) is supplied, without manipulation thereof. Thus, the control operation for obtaining a variety of effects in the instrument is greatly facilitated.

Referring now to FIG. 5', there is shown a modification of each of the muscular voltage processing circuits E,, E E,,, in which, for noise rejection, a non-linear circuit 11 (see, e.g., Reich, Functional Circuits and Oscillators, 1961, pages 297-306 and a bandpass filter 12 are series-connected between the amplifier A, and rectifier circuit 13. Thus, thecircuits l1 and 12 can serve to reject electromagnetically or electrostatically induced noise component which is contained in the picked-up muscular voltage as shown in FIG. 6A,

developing a waveform as shown in FIG. 6B. Such a waveform is passed through the rectifier 13 into the waveform of FIG. 6C.

Now, the muscular voltage thus derived, of course,is applicable to various controls of other musical instruments, e.g., an electric guitar or an electric piano, and to the control of devicesprovided in electric or electronic musical instruments.

These shielded wires which are 'capable of transmitting the picked-up muscular voltages are connected to stationary contacts 8,, S, and S, of onepole three positions type changeover switch S positioned at an upper portion of the front plate of the console, the movable contact of which may be connected to a muscular voltage processing circuit E as shown in FIG. 7D. Alternatively, one or all the hot sides of the receptacles may be connected to the movable contact of the switch S with the stationary contacts being connected to respective muscular voltage processing circuits E E and E through shielded wires 37a, 37b and 370, as shown in FIG. 7E.

FIG. 8 shows another example of the muscular voltage transmission route similar to that shown in FIG. 7A. In this example, however, the shielded wire comprises paired conductors incorporated therein.

FIG. 9A shows a modification of FIG. 7A, in which a junction box is provided in a chair for the player to connect the outputs of muscular voltage pickup means to muscular voltage processing circuits housed in the console of the instrument. The one-pole three positions type changeover switch S may also be housed in the chair instead of the console, as shown by S Alternatively, the muscular voltage processing circuits may also be housed in the junction box.

In FIG. 98, there is illustrated a manner in which an external lead wire is detachably secured to the junction box.

A to 108 show several examples of the muscular voltage pickup means of the present invention, in which numerals 76a and 76b represent a pair of electrodes, numeral 81 lead conductors, numeral 77 an adhesive mount formed of a cloth or a plastic film and provided with said paired electrodes with a suitable distance left therebetween.
