Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a metronome signal display device, and more particularly to a device for obtaining silent electromotor impulse beat signals without acoustic interference.

Conventional metronome devices transmit signals to the user by the eyes, ears, or both. For this purpose, this type of device provides a precise signal, either as an audible guide with a regularly correctly repeated ticking sound, or as a visual metronome signal, by means of a flashlight or a pendulum. I try to clearly indicate the beat.

However, these audible (acoustic) and visible (optical)
All types of metronome signals have the disadvantage that they can interfere with the user's concentration. For example, while composing music, the tone and tone of an audible metronome signal can be distracting. In addition, a visible metronome signal may interfere with reading musical notation.

An important object of the present invention is to overcome the drawbacks of conventional types of metronome signals and to obtain a novel device for time signature signal transmission.

Another object of the invention is to obtain a device for transmitting noise-free electrical motion impulse signals that does not emit any sound.

Yet another object of the present invention is to provide a new and improved system for silent signal display using a user-portable device.

The metronome signal display device of the present invention comprises a silent beat signal generator, a control device for the beat signal, and a device for converting the beat signal into movement impulses and transmitting the impulses to the user, The device comprises an actuator and a soundproof transmission device actuated by the actuator to convert said beat signal into a silent but perceivable impulse, said actuator being connected to said transmission device. It is characterized in that it operates to produce an oscillatory, reciprocating impulse movement.

Other objects, features and advantages of the present invention will become apparent from the following description with reference to the accompanying drawings:
The present invention is not limited to this, and various design changes can be made without departing from the gist of the present invention.

Metronome signal display device of the present invention (Figs. 1 and 2)
It is desirable that the size and shape of the device (Figure) be such that it can be carried by the user. For this purpose, the device has a generally square base body 11 of durable plastic material. This base body 11 has a snap-removable cover 12. For this purpose, the rim 7 flange 13 with an inwardly projecting flange 14 is elastically connected to the locking shoulder 15 on the inside of the fitting groove 17 forming an upwardly directed shoulder in contact with the end face of the flange. engage with.

In the case space 18 formed by the assembled base body 11 and cover 12, a mechano-electrical device is provided which generates a silent but physically perceptible metronome signal impulse without acoustic interference. This arrangement has a pair of counterbalanced, cooperating electromagnets 19 mounted in diametrically opposed bosses 20 which are mounted on the substrate 11. is preferably formed inside an integral thickened portion 22 and located at the edge of a cavity 21 forming an opening of the case.

The arrangement and relationship of the electromagnets 19 described above are as follows. That is, when the electromagnets are energized, they are connected to the arm 2 of the metronome impulse transducer, which is usually through an air gap.
Attract 3. This transducer has a disc-shaped member 24 of magnetic material such as soft iron, and an arm 23 integral with the member extends from diametrically opposed edge positions of the member in the tangential direction.
It protrudes to be actuated by an electromagnet 19. Said transducer member 24 is preferably supported by a sound-insulating, relatively flexible, curved pad 25.

The outer surface of the member 24 is fixed to most of the inner surface of this pad 25. On the other hand, the arm 23 protrudes from the edge of the inner surface of the member 24. Although any suitable material may be used for the pad 25, soft rubber or rubber-like elastomer is preferred. The outer surface of this pad 25 preferably has an array of protrusions 27 with a cloth-provided surface. The pad 25 has an attachment portion on its periphery for attaching the pad to the base body 11. Preferably, this mounting portion comprises a flange 28 having an integral peripheral edge, the flange comprising:
Said open cavity 21 formed by the thick part 22 of the base body
It is adapted to press firmly against the frustoconical shoulder 29 of the outwardly open annular cavity 31 concentric with the . The tightening ring 31 is screwed into the base body 11 in an annular cavity by a screw 32, and its frusto-conical tightening surface 33
Then firmly tighten the 7-lunge 28 of the pad 25 against the shoulder 29.

The pulsing motion of the electromagnet 19 is effected by an electrical device having an electrical circuit 34, the elements of which are attached to a circuit board mounted on the top inner surface of the cover 12 and supported by a thin mounting panel 37. 35 (Figures 1, 2 and 3). Devices such as a pulse cycling transistor 38, a capacitor 38a (digital circuitry may alternatively be used) are connected to a power source such as an electromagnet 19 and a battery 39. The circuit open/close switch 40 is
It has a suitable actuation device conveniently mounted on the cover 12. Pulse frequency or beat controller 41 in the circuit
is preferably adjusted by a knob 42 conveniently located on the cover 12, and an indicator 43 is provided so that the adjustment status can be indicated by a scale 44 for beat or pulse repetition rate. With this device, when the circuit is closed, the electromagnet 19 is energized and deenergized at a frequency determined by the adjustment of the time controller 41. Electromagnet 1 for each cycle
During the respective energization of 9, the arm 23 of the impulse signal display device is attracted to the electromagnet, but is prevented from coming into contact with the electromagnet by the sufficiently elastic pad 25 and then returned by deactivation of the electromagnet. This causes impulse transducer member 24 to push pad 25 outward, simultaneously creating a slight counterclockwise torque as shown in FIG. 1, and then returning due to the elastic return action of pad 250. As a result, the protrusion 27 transmits an impulse to the user's skin S (FIG. 2) that is in contact with the pad surface provided with the cloth. Thus, the user is taught the beat by sensing impulses through the skin. In FIG. 1, double-headed arrow 45 indicates the vibration cycle of transducer member 24 when actuated by electromagnet 19 in alternating pulses and returning occlusions. The double-headed arrow in FIG. 2 indicates the axial impulse and return cycle of the transducer member 24. As a result, the user is given a dual sensation of distinct twisting and pushing upon the impulse. This is particularly effective when a cloth is interposed between the device 10 and the user.

For convenience of use, the device 10 is sized to fit into a clothing pocket and has an impulse pad 2 in contact with the user's body.
5. If desired, the device 10 may be attached to the arm, leg or other convenient part of the user's body; for this purpose, the device 10 is attached to ears 49 at suitable locations on either side of the base 11 of the device. A string 48 may also be attached.

A device may be provided for connecting multiple signal display devices 10 together in order to teach time signatures to multiple people at the same time. For this purpose, the device is provided with one or more jacks 50. This jack is connected to circuit 34 in parallel with electromagnet 19, as best seen in FIG. In such a device, since the additional metronome signal display device operates in a dependent relationship, only the metronome signal display device consisting of the electromagnet 19 and the member 24 having the pad 25 and the arm 23 is required, and the electromagnet 19 can be completely equipped. Since this additional metronome signal display device can be connected in parallel with the device 10, the other parts may be removed as a subordinate type of the device 10.

A parallel arrangement of slave devices 53 for simultaneously transmitting beat pulses to a plurality of people is shown in FIG. All slave devices 53 are connected in a slave relationship to one control unit 54 common to them all. Each slave station has a thin flexible fixed or plug-in lead connection 55 to the unit 54, respectively, and is equipped with the metronome impulse conversion and transmission device shown in FIGS. 1 and 2 or an equivalent device. What you have is fine. The control unit 54 includes the circuit 34 of FIG.
1, but the power supply capacity is increased to accommodate the plurality of slave devices 53. This additional capacitance is supplied by an adapter 57 from a suitable power source.

The control unit 54 may further include an on/off switch 58 and an accessible frequency or beat control 59 similar to the control device 41 .

Additionally or alternatively, the control unit 54 includes:
Metronome impulse signal generation circuit 34 of controller 59
A conductor's baton 60 having a handle 61 with a digital switch 62, such as a manual pulse impulse generator, adapted to override or bypass the conductor's baton 60, may be connected. A thin flexible lead 63 connects the baton 60 with the controller 59. As can be seen from the above description, the apparatus of FIG. 3 can be used by a single conductor to direct the time signatures of a plurality of players in an orchestra.

FIG. 5 shows a circuit with multiple beat command options including a manual beat impulse signal display. For this purpose, a desired number of slave devices 53 are connected to the circuit 3 of FIG.

7) accordingly closes the pulse generating circuit 65 parallel to
Simultaneously activates the slave device solenoid 19'. In this way, all slave devices are actuated to transmit a stable and desired metronome pulse impulse through these slave devices.

When the conductor is faced with music that requires fast, slow, or flexible time signatures, turn on/off switch 5.
8 can be opened to manually control the beat via the slave device 53. In this manner, the conductor can be activated by pressing a normally open switch 62 supported by his baton. As shown, the manually operated normally open switch 62 is connected to the pulse generating circuit 65 such that each time the switch is closed, the pulse generating circuit 65 is closed and all slave devices 53 are actuated. . Conducting with silent time signatures, whether mechanical or manual, gives the conductor more freedom in using his baton to perform his own interpretation of the musical expression of the work, but by not pressing switch 62, You can use your baton normally. When conducting is based on mechanical timing, the conductor can use one of the slave devices 53 to monitor the beat himself. Of course, the controller may be placed near the conductor during use so that the conductor can access the control knobs.

If the musical activity is not limited to a fixed location, the metronome signal can be transmitted from the control unit 54 to the slave device 53 by radio waves or wireless control; such an implementation is easily obtainable with the current state of electronic technology. It will be done.
