Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention has a simple structure, can be played in the same manner as a normal no-note cymbal, and can be played during open hitting (normal hitting with a mallet) and pedal hitting ( An electronic device that electrically switches the musical tone signal circuit in different performance modes such as hitting by pedal operation) and close hitting (hitting with a mallet while the pedal is depressed) and generates a musical tone according to the playing mode. Concerning bibat cymbals.

[Prior art]

A detection means attached to an electronic bibat cymbal detects performance information according to the sound intensity of the cymbal, and a musical tone signal corresponding to the sound of the cymbal is detected by controlling a sound source circuit based on the detection signal. It is something that generates. In that case, even with electronic noi hat cymbals,
Ideally, it should be played in the same manner as the bibutt cymbal as a natural instrument, with the same effect. Since it is possible to selectively switch between playing with the pedal (pedal striking), playing with the pedal (pedal striking), and striking with a mallet while keeping the pedal depressed (close striking) during the performance, the above three playing methods can also be used with electronic bibat cymbals. If this is possible, it is required to identify each performance style and switch to a musical tone signal circuit corresponding to the style.

By the way, the conventional electronic bi-butt stand has an upper cymbal and a lower cymbal like a normal bi-butt cymbal used as a natural musical instrument, and a detection device installed on the upper cymbal is activated when the instrument is struck open, and when it is struck close. In some cases, a detection device installed on the lower cymbal is activated, and the pedal strike is only processed by ON/OFF signal processing using a separately installed switch. A switch is provided to distinguish between open and closed strikes (in this case, one detection device is used), and pedal strikes are turned on by another switch.
A method for creating an OFF signal is introduced. However, in both the former and latter, it has been impossible to obtain information on the strength of the blow when the pedal is struck. Also, since it is necessary to attach a detection means to the upper cymbal that moves up and down,
There was also a problem with the durability of the detection means.

[Summary of the invention]

This invention was made in view of the above points,
A cymbal is arranged at the upper end of the bibat stand, and this cymbal is connected to a detecting means for detecting performance information corresponding to the cymbal sound intensity, and a signal from this detecting means is sent from a signal circuit during oven striking to a pedal striking during pedal striking. A first switch for switching to a signal circuit and a second switch for switching from a signal circuit for pedal strike to a signal circuit for close strike are provided, and the cymbal is struck when the pedal of the bi-bat stand is depressed by a certain amount. By arranging and configuring a striking arm that operates the first switch at the same time and a switch arm that operates the second switch when the pedal is depressed by more than a certain amount, To provide an electronic bibat cymbal that can be played using the same playing method as a cymbal.

Hereinafter, based on the embodiments of this invention shown in the drawings =3 = Explain in detail.

〔Example〕

FIG. 1 is a side view showing one embodiment of the electronic inno-tcymbals according to the present invention, FIG. 2 is an enlarged cross-sectional view of the main parts, and FIG.
The figure is a switch circuit diagram. In these figures, the bibat stand 1 has three legs 2a, 2b, 2c (2b
.
An extension rod 7 that is commonly inserted through the lower pipe 3 and the upper pipe 5 and whose lower end is connected to a pedal 6 and is movable up and down, and a spring storage case 8 that is disposed at the lower end of the lower pipe 3 in parallel thereto. A cymbal 15 is disposed on the upper end surface of the upper pipe 5 via a receiving plate 14.

The cymbal 15 serves as an upper cymbal and a lower cymbal, and is made of metal, plastic material, etc. and has a disk shape in plan view, and has a cross-sectional shape of approximately 100 mm. It is composed of a hit part 15A that is semicircular or crescent-shaped and approximately beak-shaped in side view, and a semicircular flat plate part 15B that is one step lower than the hit part 15A. Hit part 15A
A well-known sensor 16 made of a piezoelectric element or the like is embedded as a detection means for detecting performance information corresponding to the sound intensity when the player is struck. In addition, the hit portion 15A
A first switch 17 is provided on the lower surface of the flat plate portion 15B.
and a second switch 18 are respectively arranged.
Actuators 17a and 18a of both switches 17 and 18 project toward the surfaces of the hit portion 15A and the flat plate portion 15B, respectively. The first switch 1T is for switching the musical tone signal circuit of the sound source circuit box 20, which is controlled by the detection signal from the sensor 16, from a circuit for oven striking to a circuit for pedal striking. It is arranged between the side open circuit 0 and switches between the open circuit O and the pedal circuit P. on the other hand,
The second switch 18 is for switching the musical tone signal circuit of the sound source circuit box 20 from a circuit for pedal striking to a circuit for closing striking, and switches between the pedal circuit P and the closing circuit C. Note that the first and second switches 17 and 18 are normally connected to the open circuit 0 and the pedal circuit P, respectively. A is a ground circuit.

The cymbal 15 of the extension rod 7 is fitted together,
Moreover, it is fixed with a fixing screw 24 so that the height can be adjusted freely. The hit portion 15 is provided on the upper end side of the outer peripheral surface of the cylinder body 25.
A striking arm 2T extending above A is integrally provided in a protruding manner. When the pedal 6 is depressed at a certain angle, the striking arm 2T descends together with the extension rod T to strike the struck portion 15A. At the time of this striking, the operator 17a of the first switch 17 is pressed down. The configuration is such that the switch 17 is operated in this manner.

The second switch 18 is located at the lower end opening of the cylindrical body 25.
A switch arm 29 is disposed corresponding to the switch arm 29, and the cylindrical body 25 is constantly urged downward between the upper surface of the base of the switch arm 29 and the lower surface of the arm receiver 23, and is pressed into contact with the flange 23a. A compression coil spring 30 is loaded. The distance between the operator 18a of the second switch 18 and the switch arm 29 is set to be larger than the distance between the operator 17a of the first switch 17 and the striking arm 27 (L>Ll). has been done. Therefore, the second
The switch 18 is not operated yet when the pedal 6 is depressed by a certain amount and the striking arm 27 hits the hit part 15A, and the switch 18 is not activated when the pedal 6 is depressed by a certain amount or more (maximum angle).
It is configured to be operated by the switch arm 29 when depressed. In this case, the striking arm 2
7 comes into contact with the hit portion 15A and is prevented from descending any further; however, the extension rod 7 further descends as the compression coil spring 30 is compressed by the arm receiver 23, so that the switch arm 29
The controller 18a can be suppressed by the controller 18a.

In such a configuration, during normal performance, the hit part 15A of the cymbal 15 is hit by a mallet, the sound intensity at that time is detected by the sensor 16, and the detection signal is guided to the sound source, circuit box 20, and the box Controls 20 circuits. At this time, the detection signal is supplied via the first switch 17 and the open circuit O to the musical tone signal circuit at the time of open hitting in the sound source circuit box 20,
The impact signal sent from the circuit is amplified by an amplifier and then emitted as a cymbal sound from a speaker (none of which is shown).

Next, when the pedal 6 is depressed by a certain amount to lower the extension rod 7, the striking arm 27 also descends together with the extension rod 7 to strike the struck portion 15A, and at the same time the first switch 17 is activated. The open circuit O of the sound source circuit box 20 is thereby switched to the pedal circuit P. Therefore, the detection signal from the sensor 16 is transmitted to the first switch 17. is supplied to the musical tone signal circuit in the sound source circuit box 20 at the time of pedal strike via the second switch 8-18 and the pedal circuit P;
The impact signal sent from the circuit is produced as a cymbal sound via an amplifier and a speaker.

Further, when the pedal 6 is depressed by a certain angle or more to lower the extension rod T to the lowest position, the switch arm 29 operates the second switch 18 and switches the pedal circuit P to the close circuit C. When the pedal 6 is held in this state, the striking arm 2T continues to press the struck portion 15A and the first switch 1T.

In this state, when the hit portion 15A is hit with a mallet, the detection signal from the senna 16 is detected by the first. Second switch 17.18 and closing circuit C
is supplied to a signal circuit at the time of a close impact in the sound source circuit box 20, and the impact signal sent from the circuit is produced as a cymbal sound via an amplifier and a speaker.

Here, the sounds emitted from each musical tone signal circuit in the sound source circuit box 20 are controlled according to the sound generation intensity of each percussion sound during open percussion, pedal percussion, and closed percussion, so that it depends on the performance mode. Reproduce the cymbal performance accordingly. Therefore, like a normal bibutt cymbal, three different playing styles are possible, each with information on the striking strength, and the performance as a musical instrument can be expanded.

FIG. 4 shows another embodiment of the electric circuit, in which the sensor 1
6 directly to the sound source circuit box 20, and open circuit 0. The pedal circuit P and the close circuit C are selectively connected to the power source 35 via first and second switches 17 and 18. R,, R2, R3 each represent a resistance, and these resistances R+, R2, R
3 may be located within the sound source circuit box 20.

In addition, although the above-mentioned Example explained the case where the striking arm 27 and the switch arm 29 were comprised by a rigid body, this invention is not limited to this and may have moderate elasticity.

Further, in the above embodiment, the sound generation intensity is detected and the sound is generated in real time, but it is also possible to memorize the sound generation timing and generate the sound in an autorhythm-like manner if necessary.

[Effects of the Invention] As explained above, the electronic bibat cymbal according to the present invention detects performance information corresponding to the sound intensity of the cymbal placed at the top of the bibutt stand when the cymbal is struck, and detects the sound source. a detection means for controlling a circuit box, and a striking arm that is provided with a first and a second switch, and operates the first switch at the same time as the cymbal is struck when the pedal of the bibat stand is depressed by a certain amount; and a switch arm that operates the second switch when the pedal is depressed by a certain amount or more, and the first switch causes a circuit in the sound source circuit box to generate a musical sound signal at the time of an open strike. The circuit is configured to switch to a musical sound signal circuit when the pedal is hit, and the second switch is configured to switch from the musical sound signal circuit when the pedal is hit to the musical sound signal circuit when the pedal is hit. Like cymbals, it can be played in three different ways. Still, the structure is simple and there is no need to move the cymbal itself up and down, so damage to the detection means can be prevented and durability can be improved.
