Description

  The present invention relates to a drum performance system and a drum performance method.

  A set of percussion instruments that produce a wide variety of different sounds have been developed. The percussion instrument set includes, for example, a drum, a cymbal, a bell, a cowbell, a hi-hat, a tambourine, a wood block, and the like. Among drums, for example, there are a wide variety of different drums such as kettle drums, steel drums, bongo drums, tam toms, bass drums, tenor drums, and snare drums. In order to add many sounds made with these different percussion instruments, different techniques for hitting or striking percussion instruments (eg, rim shots, etc.) have been developed to obtain different sounds from either instrument.

  Conventionally, however, the percussion instrument is arranged at a fixed position with respect to the performer (that is, the percussion instrument player). Because instruments take up space, there was a limit to the total number of instruments that could form part of any percussion instrument set. In addition, the fixed position of each instrument limited the number of sounds that a percussion instrument set could produce.

  The present invention has been made to solve the above-described problems, and one object of the present invention is to provide a drum performance system and a drum performance method capable of producing a wider range of sounds and rhythms. That is.

  Preferably, the drum playing system further includes a stand operably coupled to the insertion / retraction mechanism and having a base.

  More preferably, the insertion / retraction mechanism includes a first arm having a percussion instrument end adjacent to the first percussion instrument and a distal free end of the first percussion instrument, a percussion instrument end adjacent to the first percussion instrument, and A second arm having a distal free end of the first percussion instrument, and operably connected to at least one of the motor and the first arm and the second arm, and at least one of the first arm and the second arm; And a gear mechanism that allows the first percussion instrument to move between an insertion position and a storage position.

  More preferably, the motor is operably coupled to the linear actuator.

  More preferably, the linear actuator includes a gear mechanism.

  More preferably, the input device includes a touch pad configured to receive an operation command in the form of a strike from a drumstick, wherein the first strike moves the first percussion instrument from the retracted position to the inserted position. Corresponding to one operation command, the subsequent percussion corresponds to a second operation command for moving the first percussion instrument from the insertion position to the storage position.

  More preferably, the controller determines a rotation direction and a rotation speed of the motor based on the operation signal and the feedback signal.

  More preferably, the feedback mechanism includes a magnet and a sensor.

  1, 2A and 2B show perspective views of an exemplary insertable percussion instrument system 1. The system 1 includes a percussion instrument 3. In the illustrated embodiment, the percussion instrument 3 corresponds to a drum. Depending on the embodiment, the percussion instrument 3 may correspond to a percussion instrument different from the drum. The insertable percussion instrument system 1 also includes a stand 5 having a base or leg 5a for supporting the stand 5 of the floor F. The stand 5 generally supports the percussion instrument 3 vertically from the floor F.

  The insertable percussion instrument system 1 also includes an insertion / retraction mechanism 7 coupled to the percussion instrument 3 and the stand 5. The system 1 also includes a pedal 9 disposed on the floor F at or near the base 5a of the stand 5. The stand 5 vertically separates the percussion instrument 3 and the insertion / retraction mechanism 7 from the pedal 9. The insertable percussion instrument system 1 also includes a cable 11 that couples the pedal 9 to the insertion / retraction mechanism 7. When the pedal 9 is operated up and down (ie, pressed and released), the pedal 9 pulls and loosens the cable 11, thereby causing the insertion / retraction mechanism 7 to move the percussion instrument 3 substantially horizontally.

  When the pedal 9 is depressed, the pedal 9 pulls the cable 11 so that the insertion / retraction mechanism 7 moves the percussion instrument 3 almost horizontally from the storage position as shown in FIG. 1 to the insertion position as shown in FIGS. 2A and 2B. Moving. When the pedal 9 is released, the pedal 9 loosens the cable 11 so that the insertion / retraction mechanism 7 returns the percussion instrument 3 substantially horizontally from the insertion position shown in FIGS. 2A and 2B to the storage position of FIG.

  In one embodiment, as shown in FIGS. 1, 2A and 2B, the insertable percussion system 1 forms part of a drum or percussion instrument set (not shown). In the set of percussion instruments, as described above, the percussion instrument 3 may be inserted by operating the pedal 9 so that the percussion instrument 3 can be temporarily used by a percussion player. For example, the percussion instrument 3 can be inserted over another instrument in the set of percussion instruments so that the percussionist 3 can use the percussion instrument 3 to perform instead of the other instruments 103. Whenever the percussionist is ready to return to playing the other instrument 103, the percussionist removes the percussion instrument 3 by operating the pedal 9, that is, stores it so that the percussionist can play the other instrument 103 for performance. Can be made available.

  In one embodiment, the insertable percussion instrument system 1 shown in FIGS. 1, 2A and 2B is struck by a downstroke or downward movement of a beater or drumstick 60, as shown in FIG. 2A. It forms part of a set of drums or a set of percussion instruments (not shown) that includes another percussion instrument 103 that is intended to be played. In this embodiment, the percussion instrument 3 may be intended to be played by being struck by an upstroke or upward movement of a beater or drumstick 60 as shown in FIG. 2B. In this setting, the percussion instrument 3 is inserted on the downstroke percussion instrument 103 and played in the upstroke in combination with the downstroke percussion instrument 103, so that the percussion instrument 3 can be used by the percussionist. By operating the pedal 9, the percussion instrument 3 can move horizontally to the insertion position above the downstroke percussion instrument 103.

  In some embodiments, the roles are reversed. That is, the percussion instrument 3 is intended to be played by being beaten with a beater or drumstick downstroke or downward movement, and the percussion instrument 3 is inserted below or below the upstroke percussion instrument.

  A percussionist can hit a downstroke percussion instrument 103 with a downstroke movement, and then hit an upstroke percussion instrument with an upstroke movement (ie, immediately thereafter). In this way, the percussionist can double the resulting amount of drum beats. That is, a conventional beat born from hitting downward and a beat resulting from hitting the percussion instrument 3 upward. Whenever the percussionist is ready to finish playing in this upstroke / downstroke mode, the percussionist can remove or store the percussion instrument 3 by operating the pedal 9.

  In the above-described upstroke / downstroke embodiments, the insertion position of the insertable percussion instrument system 1 is such that most of the performance surface of the upstroke drum (for example, the head of the percussion instrument 3) is played by the downstroke drum 103. It may correspond to a position facing most of the surface or overlapping vertically. On the other hand, the insertion position of the insertable percussion instrument system 1 is such that most of the performance surface of the upstroke drum (for example, the head of the percussion instrument 3) does not face most of the performance surface of the downstroke drum 103. Alternatively, it may correspond to a position that does not overlap vertically.

  In the illustrated embodiment, the insertion / retraction mechanism 7 includes a first arm 13 and a second arm 15.

  FIG. 3 shows a perspective view of an exemplary first arm 13. The first arm 13 includes a percussion instrument end 13a that is operably and rotatably connected to the percussion instrument 3, as shown in FIGS. 1, 2A, and 2B. The first arm 13 also includes a joint end 13 b distal to the percussion instrument 3. The joint end 13b is connected to the second arm 15 so as to be operable and rotatable.

  FIG. 4 shows a perspective view of an exemplary second arm 15. The second arm 15 includes a stand end 15 a that is operatively and rotatably connected to the stand 5. The second arm 15 also includes a joint end 15b that is distal to the stand 5 and operably and rotatably coupled to the joint end 13b of the first arm 13. The second arm 15 also includes a pulling position 15 c where the second arm 15 can be operably connected to the cable 11.

  By pulling the cable 11 by operating the pedal 9, the second arm 15 is rotated around the stand end 15a and the joint end 15b, the first arm 13 is rotated around the joint end 13b, and The insertion / retraction mechanism 7 is effectively extended at the percussion instrument end 13a, thereby moving the percussion instrument 3 away from the stand 5 to the insertion position horizontally.

  By loosening the cable 11 by operating the pedal 9, the second arm 15 is rotated around the stand end 15a and the joint end 15b in the opposite direction to the insertion, and the first arm 13 is rotated at the joint end. Rotate around 13b and effectively retract the insertion / storage mechanism 7 at the percussion instrument end 13a, thereby moving the percussion instrument 3 horizontally toward the stand 5 in the storage position.

  In the illustrated embodiment of FIGS. 1, 2 </ b> A and 2 </ b> B, the insertable percussion system 1 includes two first arms 13 each having a percussion instrument end 13 a proximate to the percussion instrument 3 and the distal end of the percussion instrument 3. A joint end 13b. In this embodiment, the insertable percussion instrument system 1 also includes two second arms 15 each having a stand end 15 a proximate to the stand 5 and a joint end 15 b distal to the stand 5. In this embodiment, each joint end 13b of the first arm is rotatably connected to each joint end 15b of the second arm, and each of the first arms 13 is around the percussion instrument end 13a and The second arm 15 can rotate around its joint end 13b and each of the second arms 15 can rotate around its stand end 15a and its joint end 15b, extending the insertion / retraction mechanism 7 to the insertion position. Or retract to the retracted position.

  In one embodiment (not shown), the insertion / storage mechanism 7 is configured in the insertion / storage mechanism 7 and includes a spring that biases the insertion / storage mechanism 7 toward storage (ie, in the storage position). . In this embodiment, by pulling the cable 11 by operating the pedal 9, the second arm 15 rotates around the stand end portion 15a and the joint end portion 15b to overcome the pulling force of the spring that extends the spring. The arm 13 rotates around the joint end 13b and the percussion instrument end 13a, effectively extending the insertion / storage mechanism 7 and moving the percussion instrument 3 away from the stand 5 to the insertion position horizontally. By loosening the cable 11 by operating the pedal 9, the tension of the extended spring allows the insertion / storage mechanism 7 to be stored in the storage position, so that the percussion instrument 3 moves horizontally toward the stand 5. Is done.

  5 to 7 show a front view, a perspective view and a side view, respectively, of an exemplary pedal 9 for an insertable percussion instrument system 1. The pedal 9 may include a foot platform 17 rotatably connected to the base 19 at a rotational position 19a. The foot platform 17 receives a person's feet or shoes playing the insertable percussion system 1. The pedal 9 may also include a riser 21 in which a rod 23 and cable wheels 25 and 27 rotating around the rod 23 may be installed. The cable wheel 27 is connected to the foot platform 17 by a cable 29. The cable wheel 25 is connected to the cable 11 and the cable 11 is connected to the insertion / retraction mechanism 7 as described above.

  By depressing the insertable percussion instrument system 1 with the foot or shoe of the person playing, the foot platform 17 rotates about a rotational position 19a. This rotation pulls the cable 29 that also effectively rotates the rod 23 and the cable wheel 25, thereby pulling the cable 11 and extending the insertion / retraction mechanism 7 to the insertion position.

  By releasing the insertable percussion instrument system 1 with the foot or shoe of the person playing, the foot platform 17 rotates about the rotational position 19a in the opposite direction of insertion. This reverse rotation loosens the cable 29 that also effectively rotates the rod 23 and cable wheel 25, thereby loosening the cable 11 and retracting the insertion / retraction mechanism 7 in the retracted position.

  FIG. 8 shows an enlarged view of an exemplary pedal 9. Specifically, FIG. 8 shows the locking or latching mechanism of the foot platform 17 while being depressed. While being depressed, the performer or percussionist moves the foot platform 17 laterally or laterally and engages the latching tab 31 connected to the foot platform 17 with the latching bracket 33 connected to the rising portion 21. Can be combined. This effectively locks the insertion / storage mechanism 7 at the insertion position.

  When the performer or percussion instrument player wants to store the percussion instrument 3 in the retracted position, the performer or percussion instrument player moves sideways or laterally in the direction opposite to when the foot platform 17 is engaged, and the latching tab 31 is moved. The latching bracket 33 can be engaged and disengaged. The performer or percussion player can release the foot or shoe from the foot platform 17 and store the insertion / storage mechanism 7 in the storage position.

  9 to 11 show a second embodiment of the insertion / retraction mechanism 7 for the insertable percussion instrument system 1. In the embodiment of FIG. 9, the insertion / retraction mechanism 7 includes a first arm 13 and a second arm 15, which are similar to the first arm 13 and the second arm 15 of the first embodiment. is there. However, in the second embodiment, the first arm 13 and the second arm 15 cross each other, and as a result, insertion and storage of the insertion / storage mechanism 7 has a scissoring effect.

  The first arm 13 includes a percussion instrument end 13 a that is operably and rotatably connected to the percussion instrument 3. In the illustrated embodiment, the exemplary insertable percussion instrument system 1 includes a slide bracket 35 that operably and rotatably couples the percussion instrument end 13 a to the percussion instrument 3. The first arm 13 also includes a joint end 13 b distal to the percussion instrument 3. The joint end 13b is connected to the second arm 15 so as to be operable and rotatable.

  The second arm 15 includes a stand end 15 a that is operatively and rotatably connected to the stand 5. In the illustrated embodiment, the exemplary insertable percussion instrument system 1 includes a slide bracket 37 that operably and rotatably couples the stand end 15 a to the stand 5. The stand end 15 a of the second arm 15 may be connected to the cable 11. The second arm 15 also includes a joint end 15b that is distal to the stand 5 and operably and rotatably coupled to the joint end 13b of the first arm 13.

  In the embodiment illustrated in FIGS. 9-11, the insertable percussion system 1 includes a percussion instrument end 13a adjacent to the percussion instrument 3, a joint end 13b distal to the percussion instrument 3, and a joint location 13c. Two first arms 13 having the same are included. In this embodiment, the insertable percussion system 1 also has two second, each having a stand end 15a adjacent to the stand 5, a joint end 15b distal to the stand 5, and a joint location 15c. The arm 15 is included. In this embodiment, each joint end portion 13b of the first arm 13 is rotatably connected to each joint end portion 15b of the second arm, and each joint position 13c of the first arm 13 is connected to the other end. The joint position 13c of the first arm 13 is operably and rotatably connected, and each of the joint positions 15c of the second arm 15 is operable and rotatable to the joint position 15c of the other second arm 15. Connected. Each of the first arms 13 is rotatable around its percussion instrument end 13a, its joint end 13b, and its joint position 13c. Each of the second arms 15 is rotatable around its stand end 15a, around its joint end 15b, and around its joint position 15c, extending the insertion / retraction mechanism 7 to the insertion position. Alternatively, the insertion / storage mechanism 7 is retracted to the storage position.

  By pulling the cable 11 by operating the pedal 9, the second arm 15 is rotated around the stand end 15a, around the joint end 15b, and around the joining position 15c. As a result, the first arm 13 is rotated around the joint end portion 13b, the percussion instrument end portion 13a, and the joining position 13c, effectively extending the insertion / retraction mechanism 7 to stand the percussion instrument 3. Move horizontally from 5 to the insertion position.

  By loosening the cable 11 by operating the pedal 9, the second arm 15 is rotated around the stand end 15a, around the joint end 15b, and around the joining position 15c in the direction opposite to that during insertion. As a result, the first arm 13 is rotated around the joint end portion 13b, the percussion instrument end portion 13a, and the joining position 13c, thereby effectively contracting the insertion / retraction mechanism 7, and the percussion instrument 3 being placed on the stand. Move horizontally to the storage position of No.5.

  In one embodiment (not shown), the insertion / storage mechanism 7 is configured in the insertion / storage mechanism 7 and includes a spring that biases the insertion / storage mechanism 7 toward storage (ie, in the storage position). . In this embodiment, the force of pulling the cable 11 by the operation of the pedal 9 is superior to the pulling force of the spring that stretches the spring, thereby causing the second arm 15 to move around the stand end 15a, around the joint end 15b, And rotate around the joining position 15c. Thereby, the first arm 13 is rotated around the joint end portion 13b, the percussion instrument end portion 13a, and the joining position 13c, thereby effectively extending the insertion / retraction mechanism 7 and the percussion instrument 3 on the stand 5 Move horizontally to the insertion position away from. By loosening the cable 11 by operating the pedal 9, the tension of the extended spring allows the insertion / storage mechanism 7 to be stored in the storage position, so that the percussion instrument 3 moves horizontally toward the stand 5. Is done.

  FIG. 12 is a perspective view of an exemplary insertable percussion instrument system 100 in a retracted position. 13 and 14 are perspective and side views of the insertable percussion instrument system 100 of FIG. 12 in the insertion position. The system 100 may include a percussion instrument 3, an insertion / retraction mechanism 105 and a stand 113.

  The insertion / retraction mechanism 105 may include a base 110, a first arm 121, and a second arm 123. Base 110 operably couples first arm 121 and second arm 123 to stand 113. The first arm 121 and the second arm 123 have percussion instrument ends 121 a and 123 a proximal to the percussion instrument 3 and free ends 121 b and 123 b distal to the percussion instrument 3. The percussion instrument ends 121 a and 123 a may be coupled to a holding element 115 such as a U-shaped metal or plastic rod, which is attached to the side of the percussion instrument 3. A holding element 115 couples the percussion instrument 3 to the insertion / retraction mechanism 105. The first arm 121 and the second arm 123 can also be slid in the direction indicated by the arrow A via the bush elements 117 a to 117 d of the base 110.

  The insertion / storage mechanism 105 may include an input device 125, a motor 127, a gear mechanism 131, and a feedback mechanism 133.

  The input device 125 may include one or more switching elements (eg, touchpads) 125a and 125b for receiving operational commands and generating operational signals that activate the insertion / storage mechanism 105. For example, hitting switching element 125a (with a beater or drumstick) corresponds to an instruction to insert percussion instrument 3, while hitting switching element 125b (with beater or drumstick) corresponds to an instruction to store percussion instrument 3. You may do it. In another example, hitting switching element 125a once (with a beater or drumstick) corresponds to an instruction to insert percussion instrument 3, and hitting switching element 125a a second time (with beater or drumstick) causes percussion instrument 3 to be hit. It corresponds to the instruction to store. In yet another example, the input device may be placed close to the floor F so that the user or performer receives an operation command in the form of one or more switching elements being stepped on by a foot.

  The insertion / storage mechanism 105 may also include a controller 137. The controller 137 receives the operation signal from the input device 125 and can determine the current position of the percussion instrument 3 by using the feedback mechanism 133.

  The feedback mechanism 133 may include Hall effect sensors 133 a and 133 b disposed on the base 110 and a permanent magnet 133 c disposed on the first arm 121. The feedback mechanism 133 determines the position of the first arm 121 along its movement with respect to the base 110, thereby determining the position of the percussion instrument 3. For example, when the permanent magnet 133c is aligned with the Hall effect sensor 133b, the percussion instrument 3 will be proximal to the retracted position, for example, 5 cm to 10 cm. See FIG. On the other hand, when the permanent magnet 133c is aligned with the Hall effect sensor 133a, the percussion instrument 3 will be proximal to the insertion position, for example 5 cm to 10 cm. See FIGS. 2A and 2B. The sensors 133a and 133b generate a feedback signal corresponding to whether the percussion instrument 3 is in the insertion position, the storage position, or any position therebetween. The controller 137 generates a command signal based on the operation signal and the feedback signal. For example, if the percussion instrument 3 is in the insertion position or the storage position, the controller 137 stops the motor 127. Otherwise, if the feedback mechanism 133 detects that the percussion instrument is simply near the insertion or storage position, the controller 137 reduces the speed of the motor 127 and the percussion instrument 3 is in the insertion or storage position. When it reaches, it will eventually stop the motor.

  The controller 137 may be a microcontroller PIC12F683 manufactured by Microchip Technology Inc. of Independence, Ohio. However, the controller 137 may include any type of controller sufficient to receive and generate the signals described above. Hall effect sensors 133a and 133b may be micropower ultra-sensitive Hall effect switches manufactured by Allegro MicroSystems, LLC of Wallesta, Massachusetts. However, the Hall effect sensors 133a and 133b may be any type of Hall effect sensor sufficient to detect the permanent magnet 133c and generate the signal described above. In any event, feedback mechanism 133 may include any other type of sensor suitable for detecting relative position information.

  The stand 113 supports and holds the percussion instrument 3 and the insertion / retraction mechanism 105 vertically away from the floor F. The stand 113 may include a securing element 113 a that couples to the insertion / retraction mechanism 105. The stand 113 may also include a joint 113b, a base 113c, and a latch 113d. The joint 113b adjusts and sets the insertion / storage mechanism 105 and the percussion instrument 3 at an angle different from the horizontal, and allows the system 100 to be folded for storage. See FIG. Thus, the insertion / storage mechanism 105 can insert and store the percussion instrument 3 along an axis different from the horizontal. The stand 113 may also be telescopic for height adjustment. The latch 133d is used to fix the height of the stand 113.

  The gear mechanism 131 includes a rack 131a and a pinion 131b. A shaft (not shown) of the motor 127 is operably coupled to the pinion 131b of the gear mechanism 131, thereby actuating the pinion 131b and rotating it in the direction of arrow A in a direction that causes the linear movement of the rack 131a. The motor 127 receives the command signal and operates the gear mechanism 131. The rack 131a is fixed to the first arm 121 (or the second arm 123) of the insertion / retraction mechanism 105, whereby when the rack 131a pushes or pulls the percussion instrument 3, the first arm 121 pushes the bushes 117b and 117c. Slide through. The second arm 123 moves with the first arm.

  FIG. 16 is an enlarged view of the base 110, the gear mechanism 131, and the stand 113 with the percussion instrument 3 in the retracted position. A shaft (not shown) of the motor 127 may be operatively coupled to the pinion 131b so that the pinion 131b rotates to linearly operate the rack 131a. For example, the controller may rotate the motor 127 in such a direction that the pinion 131b operates and rotates counterclockwise as indicated by arrow B. As a result, the pinion operates the rack 131a linearly as indicated by an arrow C. When the rack 131a moves, the first and second arms 121 and 123 slide in the same direction to move the percussion instrument from the storage position to the insertion position. The reverse movement of the motor 127 operates the gear mechanism 131 in the reverse direction to return the percussion instrument 3 from the insertion position to the retracted position.

  17 is a perspective view of the exemplary insertable percussion system 100 of FIG. 12 forming part of a drum or percussion instrument set. In this percussion instrument set, the percussion instrument 3 may be inserted by the operation of the motor 127 as described above so that the percussion instrument player can use it temporarily. For example, if the percussion instrument 3 is inserted above the second percussion instrument 103 of the percussion instrument set, the percussion player can use the percussion instrument 3 in addition to the second percussion instrument 103. The insertion position corresponds to a position where most of the performance surface of the first percussion instrument 3 faces most of the performance surface of the second percussion instrument 103 or overlaps them perpendicularly. Such a percussion instrument set takes up little space to play and can increase the variety of sounds played, thereby increasing the enjoyment of playing and listening to the percussion instrument set. As another example, the second percussion instrument 103 may be replaced with another kind of instrument. Whenever the percussion player wants to play only another instrument, the percussion instrument 3 can be removed or stored by the operation of the motor 127, and the percussion instrument player can use another instrument.

  The term “percussion instrument” as used herein generally refers to a musical instrument and its electronic equivalent that can be produced by hitting the instrument with a hand, beater, stick or the like. Examples of percussion instruments include drums, cymbals, bells, cowbells, hi-hats, tambourines, wood blocks, kettle drums, steel drums, bongo drums, tam toms, bass drums, tenor drums, snare drums and the like. The term “drum” as used herein refers to any type of percussion instrument having at least one stretched film or an electronic equivalent thereof that generates sound by acoustic vibration when the stretched film is struck. Corresponds to an object (for example, an electronic drum pad).

  Illustrative systems, methods, etc. are illustrated by describing examples, and examples are described in considerable detail, but these details are not intended to limit or in any way limit the scope of the appended claims .

Additional advantages and modifications will be readily apparent to those skilled in the art. Accordingly, the invention is not limited to the specific details and illustrative examples shown and described. Thus, this application is intended to embrace alterations, modifications, and variations that fall within the scope of the appended claims. Moreover, the above description does not limit the scope of the present invention. Rather, the scope of the invention is to be determined by the appended claims and their equivalents.

  Insofar as the term “in” or “into” is used in the specification or claims, it is intended to mean additionally “on” or “onto”. Further, to the extent that the term “connect” is used herein or in the claims, it is not only “directly connected” but also connected via another component, etc. It is also intended to mean “indirectly linked”. An “operable connection” or entity in which an entity is “operably coupled” is that the entity or operable connection to which it is operatively performed performs its intended purpose. For example, two entities may be operatively connected to each other directly or via one or more intermediate entities.

  To the extent that the term “comprising” or “including” is used as a transition term in a claim, as long as it is used in the detailed description or the claims, It is intended to be comprehensive in the same sense as the term “comprising”. Further, the term “or” is intended to mean “A or B or both” as long as it is used in the detailed description or the claims (eg, A or B). To do. Where the applicant intends to represent “only A or B but not both”, the term “only A or B but not both” is used. Thus, the use of the term “or” in the specification is inclusive and not exclusive.
