Definitions

  • This invention relates to silent metronomic signal pulsing devices.
  • 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 oscillating light or pendulum.
  • Another is a combination of the audible type with a skin felt addition and is known from US-A-2,535,809, cf the first six lines of claim 8 specifying "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 column 1, lines 25 to 28 specifying: "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 is regulated by a clockwork mechanism including an escape wheel, 8 striking members and pallet fingers.
  • the impact actions by the striker members of the escape wheel against the pallet fingers cause the casing to resonate and the shaft transmits the impact to the diaphragm 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 synchronising or inter-connecting 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.
  • a silent metronomic signal pulsing device comprising: a housing having an opening; a transmitter fixed across said opening and having a face projecting from said housing for tempo-signal-imparting engagement with a user; transducer means comprising a disk-like member movable with said transmitter; dynamoelectric means having a part fixed to said member and a part fixed to said housing and operable for pulsing said member and thereby actuating said transmitter for tempo signal guidance of the user without acoustical interferences; and electrical means for controlling the pulsing tempo of the dynamo-electric means, characterised in that said face is texture accentuated by an array of projections which in operation thrust toward and tacitly impart a silent motion impulse to the skin of the user contacted by the pad face of the transmitter so that the transmitter is soundproof and clap-proof, and in that the member is fixed to said transmitter.
  • the signal impulse generating means in US-A-2,535,809 which consists of striker members, pallet fingers, diaphragm as well as the mechanical clockwork is replaced by a dynamo- electrical 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 pulsing means in the device can also be inter-connected in multiple circuit to separate units in a synchronised manner and a master signaller 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 activated, a wireless system which can be easily achieved in accordance with the present state of electronic arts.
  • a method of use of the metronomic signal pulsing device mentioned above for metronomic tempo signalling comprising: generating silent tempo signals from a metronomic signal generating circuit through driving by a conductor; controlling said tempo signals so as to vary their tempo; and translating said signals dynamo-electrically into mechanical silent motion impulses by plural soundproof transmission means and thereby transmitting the impulses to plural users so that the plural users simultaneously receive tempo guidance by feeling said impulses silently.
  • Figures 1 and 2 show the portable device comprises a body base portion 11 of which is moulded from a suitable plastic material. Removably carried by the base 11 is a snap-on detachable cover 12 so that the rim 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 the flange 13 seats.
  • dynamo- electric means are provided inside 18 the device for generating tacit metronomic signal impulses, comprising in a preferred arrangement a balanced, co-operative pair of agitator electro-magnets 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.
  • the transducer 24 is carried by a soundproof relatively soft, yieldably movable transmission pad 25 having a surface area facing inwardly and to which area is secured fixedly the outwardly facing surface of the member 24, while the arms 23 project from the inwardly margin of the facing surface of the member.
  • the pad 25 of rubber or rubber-like elastic material desirably has an array of interspersed mode projections 27 providing a texture accentuated, an air cushioned or clap-proof face.
  • the pad 25 has means for securing it to the base member 11, comprising a preferably continuous peripheral attachment flange 28 which is adapted to be firmly clamped against an annular frusto-conical shoulder 29 provided in annular outwardly opening groove cavity 30 concentric with the outwardly opening cavity 21 in the thickened base area 22.
  • a clamping ring nut 31 is adapted to be threadedly engaged by means of threads 32 with base 11 within the annular cavity 30 and driven with its complementary frusto-conical clamping surface 33 against the pad flange 28 of the pad 25 to clamp it securely against the clamping shoulder 29.
  • pulsing operation of the electro- magnets 19 is adapted to be effected by electrical means ( Figures 1, 2 and 4) comprising an electrical circuit 34, components of which may be carried on a circuit board 35 mounted as by means of a thin mounting panel 37 on the inside roof surface provided by the top of the cap 12.
  • Means such as a pulse cycling transistor 38 and capacitor 38a (a digital circuitry may be alternately employed) are connected electrically to the electromagnets 19 and to a power source such as a battery 39.
  • An on/off electrical switch 40 for the electrical circuit has suitable actuating means mounted conveniently on the cover 12.
  • a pulse frequency or tempo control 41 in the circuit 34 is adapted to be adjusted as by means of a knob 42 located on the cover 12 and desirably provided with an indicator 43 for visualising adjustment relative to a tempo or pulse rate scale 44.
  • the electro-magnets 19 are energised and de-energised with a frequency determined by the adjustment of the tempo control 41.
  • the impulse signalling device arms 23 are drawn toward, but the sufficiently resilient pad 25 prevents contacting, the electromagnets and then released on de-energising of the electro-magnets.
  • the device 10 may be carried in a garment pocket with the impulse 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.
  • the device 10 may provide with multiple circuit jack outlet 50 to which a lead connection 55 to slave unit 53 may be plugged in.
  • the slave unit 53 is a stripped down version of device 10 that contains electro-magnets 19 and transmitter means 23, 24, 25 and it is powered by the signal pulsing component of a device 10 or an equivalent master signaller 54.
  • Figure 3 depicts a multiple signalling where the equivalent signaller 54 is of increased capacity to accommodate the power demand from a large number of units 53.
  • a DC adaptor 57 Connected to the master signaller 54 are a DC adaptor 57 to supply extra power when needed and an adaptor cord 63 leading to a conductor's baton 60 for effecting manual tempo signalling.
  • Each pulse closes a synchronising relay switch 64, preferably of a silent kind that having a similar function as switch 62 in closing the pulsing circuit 65, which correspondingly actuate the solenoids 19' of the slave units synchronously, thereby a multiple signalling of a steady tempo is effected.
