Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention has a simple structure and can be played in the same way as a normal high-hat cymbal. ), relates to an electronic high-hat cymbal that is capable of electrically switching the musical tone signal circuit in different performance modes during close hitting (hitting with the stay while the pedal is depressed) and generating musical tones according to the playing mode. .

[Prior art]

The electronic high-hat cymbal uses a detection means attached to the cymbal to detect performance information according to the sound intensity of the cymbal, and controls a sound source circuit based on this detection signal to generate a musical sound signal corresponding to the sound of the cymbal. It is something that generates. In that case, it is ideal to play the electronic high-hat cymbal in the same way as the high-hat cymbal as a natural instrument, and to obtain the same effect and effect, but there are three types of playing methods for the high-hat cymbal: In other words, it is possible to selectively switch between the stick-based playing method (open hitting), the pedal-based playing method (pedal hitting), and the playing method of hitting with the stick while maintaining the depressed state of the pedal (close hitting) during the performance. If the above three types of playing methods are also enabled,
It is required to identify each performance style and switch to a tone signal circuit corresponding to the style.

By the way, in the conventional electronic high-hat stand, an upper cymbal and a lower cymbal are provided like a normal high-hat 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 signals using a separately installed switch. A switch is installed to distinguish between open and closed strikes (in this case, one detection device is required), and a separate switch is used to generate ON/OFF signals for pedal strikes. However, before these
In both cases, it was impossible to obtain information on the strength of the impact during pedal impact. Furthermore, since it is necessary to attach the detection means to the upper cymbal that moves up and down, there is also a problem in the durability of the detection means.

FIG. 1 is a side view showing one embodiment of an electronic high-hat cymbal according to the present invention, FIG. 2 is an enlarged sectional view of the main part, and FIG. 3 is a switch circuit diagram. In these figures, a high hat stand 1 includes a lower pipe 3 held by a foldable stand support leg 2 consisting of three legs 2a, 2b, and 2c (2b and 2c are not shown), and a lower pipe 3 held by a foldable stand support leg 2, and this lower pipe. an upper pipe 5 whose height is adjusted by a thumbscrew 4 screwed into the upper pipe 3; and an extension rod which is inserted in common through the lower pipe 3 and the upper pipe 5 and whose lower end is connected to a pedal 6 and is vertically movable. 7, and a spring storage case 8 disposed parallel to the lower end of the lower pipe 3.
a tension coil spring 13 which is housed in the extension rod 7 and provides an upward return habit to the extension rod 7;
A cymbal 15 is disposed on the upper end surface of the upper pipe 5 via a saucer 14.

The cymbal 15 serves as both an upper cymbal and a lower cymbal, and is made of metal, plastic, etc. and has a disk shape in plan view, and has a substantially square cross-sectional shape so that it is approximately semicircular in plan view. Alternatively, the hit portion 15 is crescent-shaped and approximately beak-shaped when viewed from the side.
A, and a semicircular flat plate portion 15B that is one step lower than the hit portion 15A.
A conventionally known sensor 16 made of a piezoelectric element or the like is embedded in an appropriate location as a hitting intensity detecting means for detecting performance information corresponding to the sounding intensity when the hit portion 15A is hit. Further, a first switch 17 (pedal operation detection means) and a second switch 18 (closed state detection means) are respectively disposed on the lower surfaces of the hit portion 15A and the flat plate portion 15B. Actuators 17a and 18a of 17 and 18 protrude to the surface side of the hit portion 15A and the flat plate portion 15B, respectively. The first switch 17 is for switching the musical tone signal circuit of the sound source circuit box 20 (judgment section) controlled by the detection signal from the sensor 16 from the circuit for open hitting to the circuit for pedal hitting. , is arranged between the positive side of the sensor 16 and the open circuit O, 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 tone generator circuit box 20 from a circuit for pedal striking to a circuit for close striking, and switches between the pedal circuit P and the closing circuit C. Note that the first and second switches 17,
18 are connected to the normally open circuit O and the pedal circuit P, respectively. A is an arm circuit.

Said cymbal 15 of extension rod 7
The outer periphery of the upper end extending upward has a flange 23a on the outer periphery of the lower end, into which the arm holder 23 for holding the cylinder 25 is fitted, and the height can be freely adjusted with a fixing screw 24. Fixed. The hit portion 15A is provided on the upper end side of the outer peripheral surface of the cylinder 25.
A striking arm 27 is integrally provided and extends upwardly. When the pedal 6 is depressed at a certain angle, this striking arm 27 descends together with the extension rod 7 to strike the struck portion 15A.At the time of this striking, the operator 17a of the first switch 17 is pressed down. Press the switch 17
is configured to operate. The cylinder body 2
A switch arm 29 is disposed at the lower end opening of the switch arm 29 in correspondence with the second switch 18, and the cylindrical body 25 is disposed between the upper surface of the base of the switch arm 29 and the lower surface of the arm receiver 23. A compression coil spring 30 is elastically loaded to constantly bias downward and press against the flange 23a. Said second switch 18
The distance L between the operator 18a of the first switch 17 and the switch arm 29 is larger than the distance _L1 between the operator 17a of the first switch 17 and the striking arm 27 (L
>L ₁ ) is set. Therefore, the second
The switch 18 is activated when the pedal 6 is depressed by a certain amount,
When the hit portion 15A is hit by the hitting arm 27, it is not activated yet, but when the pedal 6 is depressed by a certain amount or more (maximum angle), it is configured to be activated by the switch arm 29. ing. In this case, the striking arm 27 comes into contact with the struck part 15A and is prevented from descending any further, but the extension rod 7 is prevented from moving downward as the compression coil spring 30 is compressed by the arm receiver 23. This allows the switch arm 29 to press the operator 18a.

In such a configuration, during normal performance, the struck portion 15A of the cymbal 15 is struck by the stick, the sound intensity at that time is detected by the sensor 16, and the detection signal is guided to the sound source and circuit box 20. control the circuit. At this time, the detection signal is supplied via the first switch 17 and the open circuit O to the musical sound signal circuit for open hitting in the sound source circuit box 20, and the hitting signal sent from the circuit is fed to the amplifier. speaker after amplification (none shown)
Pronounced more like a cymbal sound.

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 operated, thereby switching the open circuit O of the tone generator circuit box 20 to the pedal circuit P. Therefore, the detection signal from the sensor 16 is supplied via the first switch 17, the second switch 18, and the pedal circuit P to the musical tone signal circuit in the sound source signal box 20 at the time of pedal strike, and from the circuit. The transmitted impact signal is sounded as a cymbal sound via an amplifier and a speaker.

Further, when the pedal 6 is depressed over a certain angle to lower the extension rod 7 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 27
5A and the first switch 17 are kept pressed.
In this state, when the hit portion 15A is hit with a stick, the detection signal from the sensor 16 is transmitted to the first and second switches 17 and 18.
and is supplied to a signal circuit at the time of a close hit in the sound source circuit box 20 via a close circuit C,
The impact signal sent from the circuit is produced as a cymbal sound via an amplifier and a speaker.

Here, the sounds produced from each musical tone signal circuit in the sound source circuit box 20 are as follows:
Since the cymbal performance is controlled according to the sound intensity of each percussion sound during pedal percussion and close percussion, cymbal performance is reproduced according to the performance mode. Therefore, like a normal high-hat cymbal, three different playing styles are possible, each with its own impact strength information, and its performance as a musical instrument can be expanded.

Figure 4 shows another embodiment of the electric circuit.
The sensor 16 is directly connected to the sound source circuit box 20, and the open circuit O, pedal circuit P and close circuit C are selectively connected to the power supply 35 via the first and second switches 17 and 18. be. R ₁ , R ₂ , and R ₃ each represent a resistance, and these resistances R ₁ , R ₂ , and R ₃ may be located within the sound source circuit box 20.

In addition, although the above-mentioned embodiment explained the case where the striking arm 27 and the switch arm 29 were constituted by a rigid body, the present invention is not limited to this, and may have appropriate 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.

〔Effect of the invention〕

As explained above, the electronic high-hat cymbal according to the present invention detects performance information corresponding to the sound intensity when the cymbal is struck on the cymbal disposed at the upper part of the high-hat stand, and controls the judgment section. A striking arm is provided that includes a strength detecting means, a pedal operation detecting means, and a closed state detecting means, and that strikes the cymbal in conjunction with depression/release of the pedal of the high hat stand,
The pedal operation detection means switches the circuit in the determining section from the musical sound signal circuit for open impact to the musical sound signal circuit for pedal impact, and the closed state detection means switches the circuit from the musical sound signal circuit for pedal impact to the musical sound signal for closed impact. Since it is configured to switch to a signal circuit, it is possible to play in three different ways, such as open hitting, pedal hitting, and close hitting, just like a normal high hat cymbal. Furthermore, since the structure is simple and there is no need to move the cymbal itself up and down, damage to the detection means can be prevented and durability can be improved.
