Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Technical Part of the Invention] This invention provides the following features in response to differences in the striking position of the striking body, etc.
This invention relates to an electronic percussion instrument that can selectively produce musical tones of different tones.

[Prior art]

The applicant has proposed an electronic musical instrument that generates a desired musical tone based on the striking or swinging of a stick. This electronic percussion instrument has a rod-shaped percussion body equipped with an electric signal generating means that is turned on at least when the percussion body is in motion or when the percussion body is swinging to generate an electric signal for producing a predetermined tone sound. It is set up and configured.

According to such an electronic percussion instrument, it has a relatively simple configuration,
A predetermined musical tone can be easily obtained by striking or shaking the striking body itself.

[Problems with conventional technology]

By the way, while the conventional electronic percussion instruments described above have excellent effects as described above, it is difficult to change the tone of the musical tone produced when the striking body is struck during the striking 'OIL'. It is necessary to operate the tone changeover switch provided on the generator side.

However, having to change and operate the tone changeover switch frequently during percussion performance not only hinders percussion performance, but also allows percussion performance to be performed only near the musical tone generator due to the operation of the tone changeover switch. I can't go.

In addition, in order to change the tone at a location remote from the musical tone generator, it is possible to provide a tone change switch on the stick body, and to change the tone as appropriate by operating the switch, but in this case. However, during percussion performance, the percussion body must be struck only after the timbre selection switch has been changed, which makes the operation complicated.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned conventional circumstances, and an object of the present invention is to provide an electronic percussion instrument that can selectively generate musical tones of a plurality of tones with simple operations.

[Key points of the invention]

In order to achieve such an object, the present invention selects the electrical contact relationship of the conductive member to each contact member in response to differences in the striking position of the striking body, etc., and thereby the musical sound generating device. The main point is that musical tones of a plurality of different tones are selectively produced.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

<Configuration of First Embodiment> FIG. 1 is a partially sectional perspective view showing a W41 embodiment of the present invention. In this drawing, the batting body side of the musical tone generator is exaggerated and drawn in a large size.

In FIG. 1, a rod-shaped striking body 1 that is struck or swung during a performance is a dog-shaped stick that is almost the same as a conventional drumstick.
They are formed to have the same external shape.

This striking body 1 includes a cylindrical stick body 2, a dome-shaped tip 3 fixed to the tip of the stick body 2, and a cap 4 screwed to the base end of the stick body 2.
It is composed of. Inside the stick body 2, there is a mounting plate 6 fixed in a predetermined position with a positioning member 5.
An insulating holding member 7 is fixed to the upper surface of the mounting plate 6. Two conductive contact members 8A, 8B are fixed to both sides of the holding member 7 so as to face each other with screws 9....

In addition, in the through hole 7a formed in the center of this holding member 7, each of the contact members 8 vibrates when the impacting body 1 is hit, etc.
A conductive coil spring 10 is press-fitted and is in electrical contact with either one of A and 8B. This coil spring 10 acts as a common contact member for the two contact members 8A and 8B, and therefore, this coil spring 10 and one of the eight contact members constitute a first switch section 11A, and this coil spring 10 and the other contact member 8B! <2 switch section 11
B is configured. In addition, each contact part USA.

The free end 10a of the coil spring 10 is attached to the tip of 8B.
A substantially U-shaped contact piece 8a to ensure reliable and stable electrical contact between the two.

8b is integrally formed (see Fig. 3). Further, when the positioning member 5 and the chip 3 are separated, the positioning member 5
A cushioning member 12 made of rubber is interposed to effectively absorb rattling. Further, on the outer surface of the stick main body 2, a first switch section 11A and a second switch section 11A and a second switch section, which are composed of the contact members 8A and 8B and a coil spring 10, are located at positions corresponding to the contact members 8A and 8B.
A musical tone name display section 13 is provided for displaying musical tone names of different tones generated based on electrical signals from the switch section 11B. This makes it possible to visually confirm the name of the musical tone to be produced by striking the striking body 1.

On the other hand, one end of a connection cord 14 is connected to each of the proximal ends 8c, 8d, and 10b of 2@'s contact sex section 8 people, 8B, and coils gelling 10, and the other end of this connection cord 14 is It is connected to a musical tone generating device 15 for generating a predetermined musical tone when the striking body 1 hits or swings. This musical sound generating device 15 can not only generate a predetermined musical sound based on the impact of the striking body 1, but also perform a dozing operation on a plurality of drum pads 16 provided on the upper part of the main body of the device. A predetermined musical tone can also be produced by pressing the six keys provided on the keyboard section 17, as in the case of a normal keyboard instrument.

Next, a circuit configuration for generating a predetermined musical tone based on the impact of the impacting body 1 will be explained with reference to FIG. 4.

As shown in FIG. 4, inside the musical tone generator 15, R
A type 3 79717171 circuit (hereinafter referred to as "R8F/FJ") 18 is provided, and the set input terminal S of this R8F/F18 is connected to the coil spring 10 and one side when the above-mentioned impacting body 1 is struck. An electrical signal generated based on the ON operation of the first switch section 11A, which is made up of eight contact members, is input, and this R8F/F18 becomes set state.The output terminal Q of this R3F/F18 is ,
A timer circuit 19 measures a chattering time (1) from the time when the first key-on signal outputted from the output terminal Q is generated based on the ON operation of the first switch section 11A when the striking body 1 is struck. Also connected is a CPU (central processing unit) 21 which controls the musical tone generator 20 to generate a predetermined musical tone based on the key-on signal. The output terminal of the timer circuit 19 is connected to the output terminal of the striking body 1 in order to prevent the generation of unnecessary musical sounds caused by the chattering phenomenon caused by the vibration of the coil spring 10 when the striking body 1 is struck once. When the first hit or the like of No. 1 is performed, a Φyy signal (reset signal) is output after a predetermined time, that is, a chattering time, based on the first key-on signal generated at that time. This carry signal is the R8F/F18
is input to the reset input terminal R of R3.
The F/F 18 enters the reset state and can again receive input from the first switch section 11A. As described above, the timer circuit 19 counts the chattering time (+1) from the time of generation of the key-on signal generated based on the first impact of the impacting body 1, etc., and this time interval (tl is determined by the CPU 21 This time interval (tl is set based on the preset time value data (p) sent from In other words, if this time interval (tl) is set too long without taking into account the time interval required for consecutive hits by the striking body 1, the striking R5F set based on the first key-on signal accompanying etc.
The set state of /F18 becomes correspondingly longer, so even if a second key-on signal occurs within a short time due to chattering during that time, the second key-on signal will not be sent to the CPU 21 side. You can do it like this,
Therefore, it is possible to reliably prevent musical sounds from being generated from the musical sound generating section 20, which is convenient. CP the key-on signal accompanying the second consecutive press
A situation occurs in which the key-on signal is not transmitted to U21@, and therefore, the musical tone generating section 20 cannot generate a predetermined musical tone in response to repeated hits based on the key-on signal. Therefore, the time interval (tl) of the timing operation of the timer circuit 19 is set to a range that is greater than or equal to the chattering time interval (t,) and less than or equal to the minimum time interval (t,) during a typical continuous hit.

Similarly, inside the musical tone generator j15, the above-mentioned R8
R8F/F same as F/F18 and timer circuit 19
22 and a timer circuit 23 are provided, and when the second switch 11B inside the striking body 1 is turned on and a predetermined electric signal is output from the switch section 11B, the R3F/F 22 is set. , this R3F/F2
2 outputs a key-on signal to the CPU 21 and the timer circuit 23. Therefore, as described above, based on the key-on signal 7, a predetermined musical tone is generated from the sound system described later, and the timer circuit 23 outputs the key-on signal. The predetermined chattering time (
After tl has elapsed, the carry signal (reset signal) becomes R3.
The signal is input to the F/F 22, and the next key-on signal is awaited. In this case, the timbre of the musical tone produced based on the key-on signal from the first switch section 11A and the second
The tones of the musical tones produced based on the key-on signal from the switch section 11B are set to be different tones from each other. Note that in this embodiment, the CPU 21
is provided with a switch 24 for variably controlling the time interval (tl) between the timing operations of the two timer circuits 19 and 23 to an arbitrary time interval manually or by foot operation.

The above-mentioned Rakuso generation section 20 uses a PCMf@ROM 25 which fixedly stores a plurality of sound source data such as predetermined percussion instruments and sampled sounds based on the PCki (Pulse-Code-Modulation) system. And this PC
The sound source data stored in the M sound source ROM 25 is converted to
Generate a corresponding predetermined musical tone based on the address system # section 26 which performs continuous control according to the control data from the PU 21 and the sound source data successively output from the P Chi Ittl OM 25 according to the control data from the address control section 26 [9 system 27.

<Operation of Eleventh Embodiment> Next, the operation of the electronic percussion instrument according to the first embodiment having the above configuration will be explained.

First, before starting percussion performance, set up the musical tone generator! 1
115 is operated to select and specify musical tones of different tones (for example, bass drum and high note).

Next, the striking body l is inserted into the chips 3, 2 and 3 of the chips 3.
When the upper curved surface in the figure is used as a striking surface, the coil spring 10 provided inside the striking body 1 vibrates in the direction of the arrow 3, and its free end 10a is electrically connected to one contact member 8A. come into contact with. Then, in accordance with the electrical contact, the first switch section 11A made up of the coil spring 10 and one contact member 8A is turned on, and a predetermined electrical signal is output from this 8gl switch section 11A. . The electric signal output from the ml switch unit 11A is sent to the set input terminal S of one R8F/F1B in the musical tone generating device 15 via the connection hood 14 wired between the striking body 1 and the musical tone generating device 115. is input, and this R8F/F1s is set. Therefore, in accordance with the set state, a key-on signal is output from the output terminal Q of the R8F/F18, and the key-on signal is input to the timer circuit 19 and to the CPU 21. Based on the medium-on signal input to the CPU 21, the CPU 21 outputs musical tone control data to the address control section 26. Therefore, the address control unit 26
Address control data is output to the Mf source ROM 25, and according to the address control data, the PCM sound source RO
One piece of sound source data stored in the M25, that is, the sound source data of the bass drum sound, is read out and the sound source data is input to the audio system 27. therefore,
A bass drum sound is emitted from the speaker SP (see FIG. 1) that constitutes this acoustic system 27.

On the other hand, when a key-on signal based on the impact of the striking body 1 is input to the timer circuit 19, the time corresponding to the preset time value that is set in advance based on the operation of the switch 24 for setting the preset time value, the timer circuit 19 The circuit 19 counts the time and sends the carry signal to R8 after counting the time.
The signal is output to the F/F 18 and the RSF/F 18 is reset. By the way, when the striking body 1 is struck once, etc., the coil spring 10b chatters with one contact member 8A due to the striking force etc., and they come into electrical contact with each other. A plurality of electrical signals may be output from the switch section 11A in a short period of time. However, even if such a situation occurs, the timer circuit 19 outputs carry No. 1 and R8F/F1
Since the plurality of electrical signals that are output until the RSF/F 18 enters the reset state are not output as key-on signals from the RSF/F 18, unnecessary musical sounds caused by chattering of the first switch section 11A are prevented from occurring. be able to. Further, after the reset state of the RSF/F18, if a second blow is repeatedly struck following the first strike of the striking body 1, the electric signal from the first switch ellA is set to R8F/F18. Therefore, this R3
Since the key-on signal will be output from F/F]8, the bass drum sound will be emitted from the speaker SP of the v-sound system 27 based on this key-on signal, similar to the operation described above. .

Next, contrary to the above case, when the striking body 1 is struck using the lower curved surface of the chip 3 in FIGS. 2 and 3 as the striking surface, the striking body 1 is struck. The coil spring O vibrates in the opposite direction (in the direction of the arrow) to that in the above case, and its free end 10a touches the other contact member 8B.
The second switch section 11B, which is made up of the other contact member 8B and the coil spring 10, is turned on. As a result, as in the case described above, the electrical signal from the second switch section 11B is R8F/
F22, and is output from this R3F/F22 as a key-on signal to the CPU 21 and timer circuit 23, and therefore, based on this -+-on signal, another f source data stored in the PCM source 1OM25 , that is, the sound source data of the bibat sound is read out, and the I! Then, the loudspeaker SP constituting the music system 27 will emit a loudspeaker sound. In addition,
After a predetermined chattering time (t) has elapsed from the time when the key-on signal is generated, the timer circuit 23 outputs a Yayari signal (reset signal) to reset the R8F/F22. Waiting for the input of the switch signal is the same as in the previous case.

<Structure and operation of second embodiment> Next, FIG. 5 is a partially omitted exploded perspective view showing a second embodiment of the present invention. Note that the same components as those in the first embodiment are given the same reference numerals and their explanations will be omitted.

In this embodiment, unlike the first embodiment, by changing the striking position of the striking body 10, musical tones of four tones can be selectively generated.

That is, in this embodiment, four conductive contact members 80 to 8F face each other on both sides of the holding member 70 disposed inside the stick body 2, and the vista...
It is fixed by. Further, in the center of the holding member 7, there is a conductive coil spring that vibrates when the impacting body 1 hits, etc., and comes into electrical contact with any one of the four contact members 8C to 8F. 10 is solidified. This coil spring 10 acts as a common contact member for the four contact members 8C to 8F, and this coil spring 1
0 and four contact members 8C to 8F, the first and second 8g3
, and W, 4 switch sections 11C to IIF are configured. As in the case of the first embodiment, contact pieces 80 to 8f are integrally formed at the tips of the four contact members 8C to 8F, and the 441VA contact members 8C
On the outer peripheral surface of the stick body 2 corresponding to ~8F, there is a tone name display section 13 for displaying the strings of the four tones...
is being carried out.

In this case, when the striking body 1 is rotated approximately 90 degrees around its axis and the striking body 1 is struck, the coil spring 10 is is in selective electrical contact with each of the contact members 8C to 8F, and first to fourth switch parts 110 are constituted by the contact members 80 to 8F and the coil spring 10.
~IIF turns on sequentially to turn on each of these switch sections 110.
Since predetermined electrical signals are output from ~11F, these electrical signals are input to the corresponding R8F/F (not shown),
Therefore, based on the key-on signal from each R8F/F,
The musical tone of the tone can be selectively emitted from the musical object system of the musical tone generator. Therefore, compared to the case of the first embodiment described above, more tones of musical tones can be produced by the striking body.
Since the sound can be generated by changing the striking position of the instrument, it is possible to perform striking performances with even greater variety.

Structure and operation of W43 embodiment> FIG. 3 is a sectional view showing a third embodiment of the present invention.

This embodiment shows a configuration example that can reliably prevent the occurrence of chattering caused by the pounding of the coil spring 10 when the striking body 1 is hit hard.

That is, in this embodiment, two contact members 8G are located within an angular range of approximately 180 degrees around the position of the quadrielectric coil spring IO disposed inside the cylindrical stick 2. , 8H are disposed, and an insulating member 29 made of a material such as rubber or plastic is disposed at a position facing these contact members 8G, 8H. Note that a buffer member 30 is interposed between the insulating member 29 and the stick body 2.

In this case, after the striking body 1 is struck quite strongly and the coil spring 10 comes into electrical contact with one contact member 8G or the other contact member 8H, each contact member 8G, 8H in the opposite direction (in Figure 5,
Even if the coil spring 10 pounds in the direction of arrow C or d), since the insulating member 29 is provided on the pound side, the contact members 8G and 8H that do not want electrical contact
It is possible to reliably prevent the coil spring 10 from coming into contact with. Then, coil spring 1
It is possible to prevent unnecessary musical tones from occurring due to zero chattering. In addition, with this configuration, chattering of the coil spring 10 can be reliably prevented, so the RSF/
An electronic circuit for preventing chattering such as F and a timer circuit can be omitted, and the circuit configuration can therefore be simplified accordingly.

<Modifications> In each of the above embodiments, a case has been described in which each switch section is turned on by the vibration generated when the striking body is struck to generate musical tones of different predetermined tones.
The present invention is not limited to this example, and even when the striking body is swung at a predetermined speed, the same actions and effects as those of the embodiments described above can be obtained. Further, in each of the embodiments described above, a case has been described in which a coil spring is used as an example of the conductive member, but the present invention is not limited to this example, and a long wire rod having a wire diameter of 4 may be used. In addition, in the above embodiments, there is a case where musical tones with two tones can be selected (in the case of the embodiment shown in Figures 1 to 3 and @ Figure 5) and a case where musical tones with four tones can be selected (
In the case of the embodiment shown in FIG. 4), however, the structure is not limited to this, and by increasing or decreasing the number of contact members, it is possible to generate musical tones of three tones, five tones or more. Good too. Further, in the embodiment described above, a case has been described in which a predetermined musical tone is generated only based on the key-on signal generated when the striking body makes the first strike, etc.
The present invention is not limited to this example, and an electric signal generated by chattering due to vibration wJ (pound) of a coil spring may be picked up as a key-on signal, and a predetermined musical tone may be generated based on the key-on signal.

With such a configuration, it is possible to continuously obtain a plurality of musical tones based on a single strike S of the striking body, and it is possible to perform a percussion instrument performance with even more variety. Furthermore, in this embodiment, a connection cord is wired between the striking body and the musical tone generating device for supplying electrical signals from each switch section to the musical tone generating device, which increases operability. Therefore, for example, FM! A wireless system may be adopted in which a transmitting section that transmits waves is provided, and a receiving section that receives the T-waves is provided on the musical tone generator side.

〔Effect of the invention〕

As is clear from the above description, the present invention is configured such that the electrical contact relationship of the conductive member to each contact member can be selected in response to differences in the striking position of the rod-shaped striking body, etc. Therefore, by appropriately changing the striking position of the striking body, the corresponding predetermined tone can be selectively emitted. Therefore, there is an excellent effect in that it is possible to perform a performance with a rich variety of playing instruments with an extremely simple operation without having to change the tone color changeover switch.
