Definitions
- the invention relates to metronomic signalling devices and ebabl- ing the practice of a method of tempo signalling comprising: means for generating silent tempo signals; means for controlling the tempo of said signals; means for translating said signals dynamoelectrically into silent motion impulses of a soundproof transmission means fixed across a housing opening and including a texture accentuated pad face projecting outwardly from said housing for tacit tempo-signal-imparting engagement with a user, and a method whereby said signals may be transmitted tacitly to a singular user or a plurality of separate users from a central location remote from said users.
- Metronomic devices make it possible to train or guide players of musical or similar activities a more accurate timing by a regularly repeated beat signals emitted from the devices at a rate ranging from 40 to 208 per minute.
- Audible (acoustic) and visual (optical) are two types of metronome widely known, while the former produces ticking sound and the latter produces oscilating light or pendulum.
- Another is a combination of the audible type with a skin felt addition and is known in accordance with the prior art portion of Claim 8 (U. S. Patent No 2,535,309) in which the device..., a case including a back wall comprising a flexible diaphragm, a timing mechanism within the case, means responsible to operation of the timing mechanism for creating uniformly periodic impacts in the diaphragm .... And, (colume 1 line 25) ...my timing device may be considered as being in the nature of a silent metronome in that it supplies sensible but substantially inaudible periodic beats.
- the device powered by a main spring 94 is regulated by a clockwork mechanism including an escape wheel 112, 8 striking members 116 and pallet fingers 58 and 60.
- the audible metronomic signals may interfere with concentration upon tone and pitch.
- Visual metronomic signals may additionally interfere with note reading.
- the prior art cited above which the inventor carefully qualifies the silent metronome'obviously is an audible type with added skin felt feature.
- a diaphragm by definition is a sound amplifying element such as one finds in a telephone receiver or the cone of a loud speaker.
- the impact actions by the striker members 116 of the escape wheel against the pallet fingers 58 and 60 cause the casing to resonate and the shaft 54 transmits the impact to the diaphragm 28 thereby causing it to amplify the striking sound further to a distinct tick similarly as a regular audible metronome.
- the ticking sound or noise will render the device useless in an actual performance such as studio recording session where the microphones are sensitive enough to pick up even a slightest sound or noise emitted by the device.
- the lack of synchronizing or interconnecting means of the device in the reference further hinders the application of a method whereby the tempo signals may be effected to a plurality of users tacitly from a central location remote from the users.
- the invention as claimed is intended to remedy these drawbacks. It solves the problem of acoustical interferences in metronomic signalling by incorporating a soundproof transmitting means which, coupled with electromagnetic actuating means, dynamoelectrically translates electronically generated or manually tapped electrical signals into silent but physically sensible metronomic motion impulses that can be felt by the user. Thereby the emitting of disturbing sound or noise in metronomic signalling is avoided.
- the signal impulse generating means in the reference which consists of striker member 116, pallet fingers 58 and 60, diaphragm as well as the mechanical clockwork is replaced by a dynamoelectrical translating means, including an elastic soundproof signal transmitting pad of soft rubber or similar material that allows imparting of silent motion impulses to the skin of the user contacted by the device without acoustic interference and, secondly, the electrical control and pulsing means in the device can also be interconnected in multiple circuit to separate units in a synchronized manner and a central control box or alternately a conductor's baton equipped with a tapping key switch can thereby effect respectively a steady or flexible tempo signals to the units.
- This method of signalling allows a conductor or director to direct musicians contacted by the separate devices to be situated unconventionally beyond his field of vision during rehearsal or actual performance. For example, they may be behind him, above him, behind the curtain or moving from place to place to enhance the phonic effect of a performance. In the latter situation, the moving musicians may carry devices that are radio wave controlled--a wireless control which can be easily achieved in accordance with the present state of electronic arts.
- dynamoelectric means are provided inside 18 the device for generating tacit metronomic signal impulses, comprising in a prefered arrangement a balanced, cooperative pair of agitator electromagnets 19 mounted in respective diametrically opposite spaced bosses 20 located at the rim of a cavity 21 defined within an integral thickened area 22 within the housing on the base member 11 and defining an opening from the housing.

Abstract
Description
- The invention relates to metronomic signalling devices and ebabl- ing the practice of a method of tempo signalling comprising: means for generating silent tempo signals; means for controlling the tempo of said signals; means for translating said signals dynamoelectrically into silent motion impulses of a soundproof transmission means fixed across a housing opening and including a texture accentuated pad face projecting outwardly from said housing for tacit tempo-signal-imparting engagement with a user, and a method whereby said signals may be transmitted tacitly to a singular user or a plurality of separate users from a central location remote from said users.
- Metronomic devices make it possible to train or guide players of musical or similar activities a more accurate timing by a regularly repeated beat signals emitted from the devices at a rate ranging from 40 to 208 per minute.
- Audible (acoustic) and visual (optical) are two types of metronome widely known, while the former produces ticking sound and the latter produces oscilating light or pendulum. Another is a combination of the audible type with a skin felt addition and is known in accordance with the prior art portion of Claim 8 (U. S. Patent No 2,535,309) in which the device..., a case including a back wall comprising a flexible diaphragm, a timing mechanism within the case, means responsible to operation of the timing mechanism for creating uniformly periodic impacts in the diaphragm .... And, (colume 1 line 25) ...my timing device may be considered as being in the nature of a silent metronome in that it supplies sensible but substantially inaudible periodic beats. The device powered by a main spring 94 is regulated by a clockwork mechanism including an escape wheel 112, 8 striking members 116 and
pallet fingers - With these types of metronomic devices they all emit signals that disturb music making. For example, the audible metronomic signals may interfere with concentration upon tone and pitch. Visual metronomic signals may additionally interfere with note reading. The prior art cited above which the inventor carefully qualifies the silent metronome'obviously is an audible type with added skin felt feature. Unless soundproof material such as soft rubber is used, a diaphragm by definition is a sound amplifying element such as one finds in a telephone receiver or the cone of a loud speaker. In the device the impact actions by the striker members 116 of the escape wheel against the
pallet fingers shaft 54 transmits the impact to thediaphragm 28 thereby causing it to amplify the striking sound further to a distinct tick similarly as a regular audible metronome. The ticking sound or noise will render the device useless in an actual performance such as studio recording session where the microphones are sensitive enough to pick up even a slightest sound or noise emitted by the device. The lack of synchronizing or interconnecting means of the device in the reference further hinders the application of a method whereby the tempo signals may be effected to a plurality of users tacitly from a central location remote from the users. - The invention as claimed is intended to remedy these drawbacks. It solves the problem of acoustical interferences in metronomic signalling by incorporating a soundproof transmitting means which, coupled with electromagnetic actuating means, dynamoelectrically translates electronically generated or manually tapped electrical signals into silent but physically sensible metronomic motion impulses that can be felt by the user. Thereby the emitting of disturbing sound or noise in metronomic signalling is avoided.
- The advantages offered by the invention are that, firstly, the signal impulse generating means in the reference which consists of striker member 116,
pallet fingers - One way of carrying out the invention is described in detail below with reference to drawings which illustrate only one specific embodiment, in which:-
- FIG. 1 is a plan view of a metronomic signalling device embodying the invention, and partly broken away and in section to reveal details, FIG. 2 is a side elevational view of the device of FIG. 1 with parts broken away and in section for revealing details, FIG. 3 is a schematic view showing how a plurality of metronomic devices according to the present invention may be motivated and controlled through a common control means, FIG. 4 is a schematic electrical diagram relevant to the operation of the device, and FIG, 5 is a schematic electrical diagram especially relevant to the arrangement of FIG. 3.
- FIGS. 1 & 2 show the portable device comprises a
body base portion 11 of which is molded from a suitable plastic material. Removably carried by thebase 11 is a snap-ondetachable cover 12 so that therim flange 13 with a lower edge inwardly projecting retaining bead 14 is retainingly engageable with a complementary latching shoulder 15 at the inner side of a rabbet groove 17 which provides an upwardly facing shoulder on which the edge of theflange 13 seats. - In accordance with the invention, dynamoelectric means are provided inside 18 the device for generating tacit metronomic signal impulses, comprising in a prefered arrangement a balanced, cooperative pair of
agitator electromagnets 19 mounted in respective diametrically opposite spacedbosses 20 located at the rim of acavity 21 defined within an integral thickenedarea 22 within the housing on thebase member 11 and defining an opening from the housing. Theelectromagnets 19, when they are energized, will attract cooperatively related, normally gapped,arms 23 of a metronomic impulse transducer of soft iron material and from which thearms 23 integrally project divergently and tangentially from diametrically opposite marginal location on thetransducer 24 and in complementary positions for actuation by therespective electromagnets 19. Thetransducer 24 is carried by a soundproof relatively soft, yieldablymovable transmission pad 25 having a surface area facing inwardly. and to which area is secured fixedly the outwardly facing surface of themember 24, while thearm 23 project from the inwardly margin of the facing surface of the member. On its outer face, thepad 25 of rubber or rubber-like elastic material desirably has an array of projections 27 providing a texture accentuated face. About its perimeter, thepad 25 has means for securing it to thebase member 11, comprising a preferably continuousperipheral attachment flange 28 which is adapted to be firmly clamped against an annularfrustoconical shoulder 29 provid ed in annular outwardly openinggroove cavity 30 concentric with the outwardly openingcavity 21 in the thickenedbase area 22. Aclamping ring nut 31 is adapted to be threadedly engaged by means ofthreads 32 withbase 11 within theannular cavity 30 and driven with its complementary frustoconical clamping surface 33 against thepad flange 28 of thepad 25 to clamp it securely against the clampingshoulder 29. - In accordance with a preferred embodiment of the invention, pulsing operation of the
electromagnets 19 is adapted to be effected by electrical means(FIG. 1, 2 & 4) comprising anelectrical circuit 34, components of which may be carried on acircuit board 35 mounted as by means of athin mounting panel 37 on the inside roof surface provided by the top of thecap 12. Means such as apulse cycling transistor 38 andcapacitor 38a (a digital circuitry may be alternately employed) are connected electrically to theelectromagnets 19 and to a power source such as abattery 39. An on/offelectrical switch 40 for the electrical circuit has suitable actuating means mounted conveniently on thecover 12. pulse frequ-ency ortempo control 41 in thecircuit 34 is adapted to be adjusted as by means of aknob 42 located on thecover 12 and desirably provided with anindicator 43 for visualizing adjustment relative to a tempo orpulse rate scale 44. Through this arrangement, when the circuit is closed, theelectromagnets 19 are energized and deenergized with a frequency determined by the adjustment of thetempo control 41. At each energization of theelectromagnets 19 in each cycle, the impulsesignalling device arms 23 are drawn toward, but the sufficientlyresilient pad 25 prevents contacting, the electromagnets and then released on deenergizing of the electromagnets. This causes theimpulse transducer 24 to push outwardly on thepad 25 and at the same time torque slightly in a counterclockwise direction as viewed in FIG. 1 and then returned by virtue of the return spring action of thepad 25. This causes the projection 27 to thrust toward and tacitly impart a silent motion impulse to the skin S (FIG. 2) of a user contacted by the pad face. In FIG. 1, the double-headed arrow 45 indicates the oscillating cycle of thetransducer 24 as it is alternately actuated in a pulse and release cycle by theelectromagnets 19. A double-headed arrow 47 indicates reciprocatory axial motion cycle of themember 24. As a result, the user receives a definite and dual combined twisting and thrust for each impulse. This is especially effective where an article of clothing intervens between thedevice 10 and the skin of the user. Thedevice 10 may be carried in a garment pocket with theimpulse transmitting pad 25 contiguous to the user's body. An attachment means (48, 49) is provided alternatively for attaching the device to the user's body. - For plural tacit metronomic signalling, as enabled by the said preferred embodiment of the invention, the
device 10 may provide with multiple circuit jack outlet 50 to which alead connection 55 toslave unit 53 may be plugged in. Theslave unit 53 is a stripped-down version ofdevice 10 that containselectromagnets 19 and transmitter means 23, 24, 25 and it is powered by the signal pulsing component of adevice 10 or anequivalent control 54. FIG. 3 depicts a multiple signalling where theequivalent control 54 is of increased capacity to accommodate the power demand from a large number ofunits 53. Connected to thecontroller 54 are aD. C. adaptor 57 to supply extra power when needed and anadaptor cord 63 leading to a conductor'sbaton 60 for effecting manual tempo signalling. Loca.ted on thehandle 61 of conductor's baton60 is a digitalkey switch assembly 62 provided for manually generating flexible tempo signals to theremote signalling units 53 or 53' as shown in FIG. 5. By tapping theswitch key 62 as flexibly in tempo as desired a correnpondingly flexible tempo signals can be generated to the units 53'. On each tap of the normally open-biased key switch 62 it closes briefly thepulsing circuit 65 across the power source 39' (or 57) and the solenoids 19' of the slave units 53' energized synchronously, thereby a multiple signalling of tempo is manually effected. By setting thedial 59 at a desired rate and thecontrol switch 58 closed,the electrical pulsing circuit 34' is energized for steady tempo pulsing action at a rate indicated on thecontrol 59. Each pulse closes a synchronizing relay switch 64, preferably of a silent kind that having a similar function asswitch 62 in closing thepulsing circuit 65, which correspondingly actuate the solenoids 19' of the slave units synchronously, thereby a multiple signalling of a steady tempo is effected.
