- ABSTRACT Improvements in the electrical reproduction of the audio output of musical instruments having vibrating surfaces reproducing said audio output illustrative examples of which are a drum and a guitar.
- Product aspects of the invention are demonstrated by the use of an improved electrical pickup that is mounted for vibration in unison with the vibrating surface and thus provides a vibrating magnetic field.
- a field-influencing magnetic body is confined within a compartment of the electrical pickup that is bounded by resilient walls that in practice causes said body to be set into vibration along with the pickup but in an out-of-phase vibratory pattern.
- the effect of the vibrating magnetic body is to provide a signal-producing movement relative to the magnetic field that effectively results in audio output reproduction.
- the present invention relates generally to improvements in the electrical reproduction of music, and more particularly to an improved electrical pickup, characterized by selective reproduction of the low and high frequency content of an audio output, which may be used with noteworthy results on a wide range of musical instruments that have a sound-producing vibrating surface.
- the pickup hereof is described in connection with a drum and a guitar.
- the preparation of the aforesaid instruments, and particularly a drum, for electrical sound reproduction has heretofore been very difficult to achieve.
- a conventional electrical pickup at least one of the signal-producing components thereof remain stationary while the others vibrate so that the resultant relative movement therebetween can be utilized to produce electrical signals that are used, in a well understood manner, to in turn produce sound.
- the aforesaid stationary mounting complicates, both in set-up time and equipment, the proper application of the pickup to the drum, and to a lesser extent to the guitar.
- the full range of the drum audio output exemplified by high frequency brush stroke sounds on the one hand and booming sounds produced by beating the drumhead on the other hand, has been difficult to faithfully reproduce by any known electrical pickup even when properly installed on the drum. It is similarly difficult to faithfully reproduce the full range of musical tones of a guitar or like stringed musical instrument.
- the entire pickup hereof is mounted on the instrument vibrating surface, such as the drumhead or guitar body, and functions properly merely upon being set into vibration by this surface, thereby obviating the need for mounting or holding any of the components in stationary relation to said instrument vibrating surface.
- An improved pickup demonstrating product aspects of the present invention includes a conventional electrical pickup and, when applied to a drum or like percussion instrument, also includes appropriate mounting means for applying said pickup and an interposed fieldinfluencing body under firm pressure against the drumhead or vibrating surface, with the result that sound reproduction is confined to the high frequency portion of the audio output, such as the brush strokes.
- the patterns of vibration of this body and of the pickup differ so that there is the requisite signal-producing relative movement therebetween, this time confined to parameters which are related to the low frequency portion of the drum audio output, such that corresponding drum sounds are readily produced therefrom.
- the pickup hereof is constructed and functions to faithfully reproduce the full range of the musical instrument to which it is applied, and furthermore does so with an exclusion of extraneous sounds since such sounds are not produced by the instruments vibrating surface.
- the aforesaid pickup and mounting is also used and applied, substantially as just described, for stringed and like instruments, except that in some instances the interposed field-influencing body which causes reproduction of the high frequency musical tones is dispensed with. In such instances, metallic strings of the instrument are situated within the pickup magnetic field and thus, when set into vibration, directly result in the reproduction of the high frequency musical tones.
- FIG. 1 illustrates the method of producing the musical tones of a drum in accordance with the method of the present invention and contains a perspective view of such instrument having an improved electrical pickup practicing the method hereof applied thereto;
- FIG. 2 is a partial elevational view, on an enlarged scale, illustrating structural details of the pickup. Moreover, since the illustrative embodiment is generally cylindrical or circular in shape, including both the external and internal parts thereof, plan views illustrating such shape have been omitted as being unnecessary;
- FIGS. 3, 4a, 4b and 5 illustrate application of the pickup hereof to a guitar, FIG. 3 being a perspective view showing several ways of mounting such pickup to this exemplary stringed instrument;
- FIG. 4a is a side elevational view, on an enlarged scale and in section taken on line 44 of FIG. 3, illustrating a mounting most similar to that of the drum of FIGS. 1 and 2 in that it includes use of an interposed field-influencing body to reproduce the high frequency tones of the strings;
- FIG. 4b is a view. similar to FIG. 40, except that another type ofmounting is illustrated therein;
- FIG. 5 is also a side elevational view, but taken in section on line 55 of FIG. 3, and illustrates still another pickup mounting in which the vibrating metallic strings of the instrument directly result in the reproduction of the high frequency tones thereof.
- pickup 10 includes as a part thereof a conventional electrical pickup, generally designated 12, conventionally constructed to the extent that it includes north and south pole pieces 14, 16, respectively, which, as generally understood, are effective in producing a magnetic field.
- a conventional electrical pickup generally designated 12
- magnetic field As an alternative to the permanent magnets 14, 16, use can, of course, also be made of electromagnets (not shown) since for purposes of the invention all that is necessary is the production of a magnetic field.
- the conventional electrical pickup 12 also includes an electrical conductor which is wound into a coil 18 in an orientation relative to the magnetic field of the pole pieces 14, 16 such that any shifting in this field'cuts the coil 18 so that, in a well understood manner, an electrical signal is produced in the coil 18.
- the conductor from which the coil 18 is made includes leads 20 and 22 which will be understood to be electrically connected to an amplifier, speakers, and other such sound reproducing equipment as is necessary to convert the transmitted electrical signals into musical tones which,
- body 50 is formed in two halves 52 and 54 which may be adhesively secured together at their periphery, as at 56. Prior to this adhesive connection, however, the medial portions of the body halves 52 and 54 have facing portions thereof removed so that when they are combined the remaining walls cooperate to bound an internal compartment 58. Disposed in the compartment 58 is a generally circular magnetic body 60 fabricated or iron or other such metal which is capable of being magnetized and thus of affecting any magnetic field in which it is placed. In this regard, the medial portion 62 of the body half 54 which, as illustrated,
- the percussion musical instrument 24 in question is one type of drum, but it will be understood that the invention is not limited to use therewith but can be used also with other types of drums, cymbals, and generally with any percussion instrument which has a vibrating surface which produces the musical tones or sounds of the musical instrument.
- the conventional electrical pickup 12 need not be limited to the'construction described but that changes may be made thereto such as, for example, the single coil 18 may in fact consist of two coils electrically connected in opposing or so-called humbucked relation.
- the improved electrical pickup l hereof is mounted directly to the drum 24 such that it is set into vibration during the playing of this instrument when the vibrating surface, in this instance the drum head 26, is
- the conventional electrical pickup 12 is embodied in the improved pickup 10.
- the' improved pickup is provided with a generally cylindrical cup-shaped external body 40, the side wall 42 of which is of an appropriate size to accommodate the electrical pickup 12 at one end thereof with the closing end wall 44 thereof spaced from the top surface 46 of pickup 12 so as to define an internal compartment 48 between wall 44 and surface 46.
- a cylindrical puff-shaped body 50 formed of a porous elastomeric material which may be a conventional sponge or the occupies an interposed position between the pickup 12 and the metal body is of a sufficient extent to prevent the magnetic capture of the body 60 by the pole pieces 14 and 16.
- the separation represented by the medial portion 62 is not that extensive as to remove the body 60 from the magnetic field produced by the pole pieces 14, 16, and in fact it is to be understood that the adjacent location of the body 60 and the pickup 12 is such that the body 60 is within the magnetic field of the pickup 12.
- the magnetic body 64 is electrically insulated by a thin layer 66 of felt, paper or the like from direct contact with the pole pieces 14 and 16 and further occupies a critical interposed position between the electrical pickup 12 and the vibrating surface 26.
- a magnetic body such as the bodies 60 or 64 are moved relative to the electrical pickup 12 within the magnetic field thereof, or if the pickup 12 is moved relative to either of these magnetic bodies, in either case the magnetic bodies are known to have that effect on the magnetic field of the electrical pickup which causes a shifting in the lines of force thereof.
- This shifting cuts the coil 18 and is similarly known to produce electrical signals therein which, after being transmitted through the conductors 20 and 22 to amplifiers and other sound-reproducing equipment, can be used, or at least it has been so found, to faithfully produce the audio output or sounds of the drum 44.
- an important aspect and contribution of the present invention is the recognition that the relative vibratory movement which is permitted between the lower body 64 and electrical pickup 12 is confined to the high frequency movement of the vibrating surface 24, whereas in contrast thereto .the relative vibratory movement between the other magnetic body 60 and the electrical pickup 12 is confined to the low frequency movement of the surface 26. lt is in this manner that the improved pickup 10 hereof effectively contributes to the reproduction of the full range of auditory output of the drum 10 including, for example, the low frequency output thereof as exemplified by the booming sounds produced by beating of the drumhead 26 and, at the other extreme, the reproduction of the high-frequency output as exemplified by brush stroking of the drumhead 26.
- upper body wall 44 is provided with an enclosure 68 for the depending end 70 of a threaded rod 72 which is threadably disposed, as at 74, in the horizontally oriented bracket leg 38.
- rod 72 hasa handle 76 affixed to it to facilitate threaded adjustment thereof. It is contemplated that rod 72 be threadably adjusted so as to firmly press the lower end of electrical pickup 12 against the diaphragm 64 and the diaphragm 64, in turn, pressed firmly into the vibrating surface 26.
- the extent of applied pressure will be understood to be such that there can be little relative vibration between the vibrating surface 26 and the electrical pickup 12 save for very high frequency vibration.
- the electrical pickup 12 similarly senses that same extent of vibration when it is pressed, as just described, firmly against the peripheral portion of the vibrating drumhead 26. In practice, it has been found that this sensed vibration is effective in producing electrical signals in the coil 18 which result in the faithful reproduction of brush strokes applied to the drumhead 26.
- the low frequency audio output of the drum 24 is converted into corresponding electrical signals preparatory to subsequent amplification and conversion back to audio output by the relative vibratory movement between the electric pickup 12, which vibrates in unison with the vibrating surface 26, and the upper magnetic body 60 which also vibrates, but in an out-of-phase vibration pattern relative to the pickup 12. That is, the vibration of the pickup 12 sets into vibration the elastomeric body 50 which is located in the oversized compartment 48 and the movement thereof, in turn, sets into vibration the body 60 which is located in the oversized internal compartment 58 of body 50.
- the vibration pattern thus induced in the body 60 is related to the low-frequency or high-amplitude movements of the vibrating surface 26 since, in practice, it has been found that this vibratory movement of the body 60 is effective in reproducing the low frequency sounds of the drum.
- the manner in which the vibrating pickup 12 sets into vibration the body 60 can perhaps best be likened to what occurs when a person shakes dice, wherein the movement of the dice within the confined area formed by the persons clenched fingers is related to the overall movement of the persons hand. In any event, as already noted, it has been found that the relative vibration between the body 60 and electrical pickup 12 results in faithful reproduction of the low frequency audio output of the drum 24.
- FIGS. 3, 4a, 4b and 5 the same reference numbers are used to designate parts already described in connection with FIGS. 1 and 2 that are similar in construction or similar in function.
- the pickup l0 hereof is shown applied to a guitar 78 including a body 80 having a top sounding board or vibrating surface 82.
- a neck 84 Appropriately extended from the body 80 is a neck 84, in the end of which are suitably disposed a number of upstanding pegs 86.
- a tail piece 88 and the pegs 86 Stretched between a tail piece 88 and the pegs 86 are the six strings 90 of the guitar 78.
- a bridge 92 which functions to properly space the strings 90 one from the other and in a clearance position above the body surface 82.
- Strings 90 will be understood to be fabricated of plastic or other nonconductive material and are seated, as already noted, in bridge 92, which will be understood to be fabricated of wood or similar nonconductive material.
- Bridge 92 is extended through an opening 94 in the surface 82 and is supported in a clearance position above the surface from below.
- bolts 96 and 98 are operatively arranged in depending relation from the surface 82 into the interior of the body 80 and are connected, at their lower end, to a bracket 100 by nuts 102, 104 threadably engaged to the bolts 96, 98.
- the outer housing or cup 40 of the pickup 10 is the outer housing or cup 40 of the pickup 10.
- the internal construction of the pickup 10 is similar to that already described in connection with FIG. 2 in that within the cup 40 there is an elastomeric body 50 having an oversized compartment 58 for the low-frequency magnetic body or diaphragm 60.
- the pickup 10 includes the usual pole pieces, one such pole piece 14 being illustrated in crossing relation to the lengthwise orientation of the strings 90.
- an insulating felt layer 66 Immediately above the pole pieces is an insulating felt layer 66 and then a high-frequency magnetic body or diaphragm 64 in interposed position between the felt layer 66 and the bottom of the wooden bridge 92.
- a coil 18 having conductors 20 and 22 through which the electrical signals are transmitted to soundreproducing equipment.
- vibration of the strings 90 produces corresponding vibration of bridge 92 and also of the body surface 82.
- vibration of the strings 90 produces corresponding vibration of bridge 92 and also of the body surface 82.
- FIG. 4b which will be understood to be similar in all respects to that described in connection with FIG. 4a, except that bridge 92 is fabricated of metal and thus can itself effectively serve the purposes served by the diaphragm 64 which can therefore be dispensed with.
- bridge 92 is fabricated of metal and thus can itself effectively serve the purposes served by the diaphragm 64 which can therefore be dispensed with.
- pickup 10 will not be, and indeed is not located where the bridge 92 is located. Rather, a different location is selected at which the upper portion or pole pieces of the pickup are projected through an opening 108 in the body surface 82 in sound-reproducing relation to the instrument strings 90 which extend in a clearance position over the pickup 10 between the pegs and bridge and tail piece 92, 88. and it will be understood that the strings 90 are metallicor otherwise fabricated of conductive material and, being within the magnetic field of the pickup 10, are thus capable, when set into vibration, of directly causing sound-reproducing signals in the pickup coil 18.
- these signals reproduce the high-frequency musical tones of the instrument whereas diaphragm 60 in the oversized compartment 58 bounded by the resilient walls 50 are effective, as already noted, in causing reproduction of the low-frequency musical tones of the instrument when set into vibration by the vibrating pickup body 40.
- the strings 90 do not exert a downward holding force 106 on the pickup 10
- an improved electrical pickup 10 which, among other noteworthy aspects, is characterized in that it is directly mounted to the vibrating surface of the musical instrument. This is in contrast to prior art electrical pickups wherein at least one part thereof, whether it be the permanent magnets, coil, or field-influencing magnetic body, is required to be stationarily mounted, and remaining parts thereof mounted for vibration in unison with the vibrating surface.
- at least one part thereof whether it be the permanent magnets, coil, or field-influencing magnetic body
- a small cymbal can be made to sound like a large, gong-like cymbal by using a comparatively large mass magnetic body 60; a large cymbal can be thinned out in the low frequencies by using a comparatively small mass magnetic body 60; and a tympani effect can be achieved on a small tom-tom by using a comparatively large mass magnetic body 60.
- the improved pickup 10 is not limited to use in conjunction with only a drum and a guitar or the like, but can also be used with good results to electrically reproduce the sounds of a piano, the said pickup 10 being applied to the sounding board of the piano.
- the improved pickup l0 hereof is directly operated by, and thus only reproduces the sounds of, the vibrating surface of the musical instrument. It is thus unaffected by extraneous noise, as is a conventional microphone or the like. This is of obvious significant advantage in recording music in that it eliminates the need for sound-proof studios and the procedures therein which are now used to avoid distracting extraneous noise or sounds in the recorded tape or record.
