DISCLOSURE
Michael McGee is the inventor of a mechanical drum tuner application filed Jan. 31, 2013 now granted U.S. Pat. No. 8,772,617 on Jul. 8, 2014.
BACKGROUND
Keeping stringed and percussion musical instruments in tune is a constant effort. Because of strings stretching, stringed instruments such as guitars generally need to be tuned before every practice use and for professional musicians, usually prior to every performance and generally “touched up” during performances. Live performance musicians playing stringed instruments will generally have multiple guitars sitting on stage or just off stage and a dedicated person to tune the instrument as it's traded off during performances for an in-tune guitar.
Percussion instruments, mainly drums, represent a completely different challenge. Drums by their very nature take longer to tune than guitars. Drums such as a “simple” snare drum contain more components that can effect the state of tune. The snare drum is composed of a hollow cylinder with a top service called the batter head and a bottom surface called a snare head. The batter and snare heads cover the ends of the cylinder/shell and are stretched under tension. Tension is maintained through a set of tension rods evenly spaced around the circumference of the drum shell. The tension rods are typically mounted to the side of the drum shell. The tension rods hold the counter hoops that retain the batter and snare heads. The counter hoops have holes evenly spaced around their circumference with the holes fitting over the ends of the threaded tension rods. Nuts secure the hoop rings to the tension rods and pull the heads down creating tension across the flexible surface of the heads. Drums generally contain 4 to 12 or more tension rods that are used to tune the surface heads by tightening and loosing the nuts retaining the hoop rings that stretch the surface heads.
A professional drum kit can contain anywhere from four to eight or more individual drums with each drum containing four or more tension rods with two nuts per tension rod giving 16 tuning points. A drum kit with five individual drums will have 80 tuning points. The time to tune a drum kit can take hours if done by ear and only slightly less time if an electronic frequency meter is used.
The challenge presented to tuning drums in orders of magnitude more difficult than tuning a guitar or other handheld stringed instrument.
Problem Statement
What is needed is some device or system to reduce both the time and the need for a skilled person to tune drum sets without needing a skilled ear or an electronic device to listen for a known frequency when the top or bottom surface of a drum is being struck by a drum stick.
SUMMARY
The instant invention discloses an automated electrically powered drum tuner controlled by a microprocessor and software. The invention may be portable and moved from one existing drum to another where the existing drums may have different numbers of tension rods and different numbers of drumming surfaces. The instant invention can be used to tune different diameters of drums ranging from small Toms in drum kits to large kettle drums to Conga drums without having to construct a mechanical support apparatus for adjusting the tension rod fixtures.
Embodiments
In a first exemplary embodiment, a drum tuning system is disclosed where in the system uses a plurality of stepper motor assemblies attached to the nuts mounted on the tension rods of a drum. The stepper motors are controlled by a microprocessor and electronic current monitors that can sense the force being used to tighten or loosen the nuts on the threaded tension rods. Once the stepper motors have applied a predetermined amount of force wherein each nut is being torqued with the same force, the surface of the batter and snare head with be in tune.
In a related embodiment, each stepper motor assembly is permanently attached to each tension rod. In this embodiment, the drum may be tuned in a matter of seconds once the tuning algorithm is initiated. This embodiment allows a drum to be tuned while being played since the state of tune is determined by the force applied to the hoop rings and not the frequency emitted as a result of heads being struck by the musician.
In a related embodiment, once initiated, the running algorithm detects when the drum is being played by monitoring a microphone attached to the interior of the drum shell. When the algorithm detects that the drum has not been struck for some predetermined number of seconds it will initiate a self-tuning sequence.
In another embodiment, a drum tuning system is disclosed wherein the system is portable and may be used to tune multiple different drums with different numbers of tension rods. In this embodiment the stepper motor assemblies are not fixed or attached to the tension rods but are individually attached to the top and bottom of the tension rods and capture each of the tension rods. The microprocessor monitoring the force being applied to the tension rods may have connections to more than the number of stepper motor assemblies. In this embodiment, the user indicates to the microprocessor the number of stepper motor assemblies required to be controlled.
Reference will now be made in detail to various embodiments, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

DETAILED DESCRIPTION OF THE INVENTION
Objects and advantages of the present invention will become apparent to those skilled in the art upon reading this description in conjunction with the accompanying drawings, in which like reference numerals have been used to designate like or analogous elements.
Now referencing FIG. 1 where 10 depicts a snare drum identifying its component parts. Snare drum 10 is composed of snare drum shell 12 which supports upper metal hoop 14 and lower metal hoop 16. Each of these hoops hold and stretch the drum surfaces. Support pins 18 are fixed to upper and lower metal hoops 14 and 16. The support pins hold the tensioning portion of auto tuner devices 100. Auto tuner devices 100, under control of a microprocessor controller 202, (shown in FIGS. 3 and 4) pull the upper metal hoop 14 down toward the center of snare drum shell 12 and pull the lower metal hoop 16 up toward the center of snare drum shell 12. Auto tuner devices 100 are fixed to snare drum shell 12 by one or a plurality of machine screws through snare drum shell 12 to auto tuner devices 100 or through a bonding material holding auto tune devices 12 to snare drum shell 21.
Now referencing FIG. 2 where 100 depicts the drum auto tuner device composed of stepper motor 102, gear transfer device 104 and gear reduction assembly 106. As stepper motor 102 is driven clockwise or counterclockwise rotational direction by microprocessor controller 202, (shown in FIGS. 3 and 4) stepper motor 102 turns and transfers torque through gear transfer device 104 to gear reduction assembly 106. Gear reduction assembly 106 multiplies the torque provided by stepper motor 102 through gear transfer enclosure 104. The revolutions per minute speed of stepper motor 102 is reduced by gear reduction device 106 which in turn increases the torque to tension assembly 108, 110, and 112. Tension assembly 108, 110, and 112 is composed of threaded drive screw 108 which in turn pulls or pushes threaded tension tube 110 toward auto tuner device increasing tension on metal hoops 14 or 16 or if stepper motor 102 turns in the opposite rotational direction, gear reduction assembly will push via threaded drive screw treaded tension tube 110 relaxing the tension on metal hoops 14 and 16. Metal connection band 112 connects threaded tension tube 110 to upper metal hoop 14 through metal support pins 18. Metal connect band 112 may be a band or a solid metal connector plate 114 with a hole the fits over metal support pins 18. In an alternate embodiment, threaded tension tube 110 is replaced with alternate threaded tension tube 116. Alternate threaded tube 116 is fixed on threaded drive screw 108 with jam nut 118. Alternate threaded tube contains a slotted cut 120 that fits onto tension rod fixture 30. In an alternate embodiment, tension rod fixture fits into alternate threaded tension tube 116 slotted end 120. When auto tune device 100 rotates threaded drive screw 108, tension rod fixture 30 rotates pulling upper metal hoop 14 or lower metal hoop 16 toward the center of snare drum cylinder 12 or loosens upper metal hoop 14 or lower metal hoop 16 removing tension on the drum surface.
Now referencing FIG. 3 where 200 depicts the control system that calibrates and maintains the tension applied by auto tune devices 100 between upper and lower metal hoops 12 and 14. Microprocessor controller 202 may be any computing device such as but not limited to a System On Chip single board computer, a smart phone, or a Personal Digital Assistant, computing tablet, laptop computer or desktop computer connected to communications bus 206 which may be a USB bus or other bus capable of connecting to a System On Chip single board computer, a smart phone, or a Personal Digital Assistant, computing tablet, laptop computer or desktop computer. Communications bus 206 is a bi-directional electronic bus and may be a USB bus, a two-conductor twisted pair serial bus, or any other bi-directional communications bus. Communications bus 206 also connects to electrical current switching device 224 which receives power from power supply 220 and provides switched electrical current to auto tune devices 208 through 214.
Microprocessor controller 202 executes software programs consisting of an operating system and software algorithms that perform the calibration and tuning functions of the invention. The number of auto tuner devices may vary depending on the size and configuration of the drum. Typically, a snare drum will have two tunable surfaces held in place by an upper metal hoop 14 and a lower metal hoop 16. Different drum types such as kettle drums may only have a single tunable drum surface.
The electrical current used to drive any of the auto tune devices is proportional to the amount of torque being created when stepping motor 102 is being actively stepped under control of microprocessor controller 202. The level of current delivered to each auto-tune device 208-214 is sensed by electrical current sensing device 218 to microprocessor controller 202 via Communications bus 206. Microprocessor controller saves the received sensor data in drum tuner database 400 (FIG. 9). The algorithms used to control microprocessor controller 202 are detailed in FIGS. 5, 6, and 7
Now referencing FIG. 4 where 450 depicts the control system that calibrates and maintains the tension applied by auto tune devices 100 between drum shell 12 and upper metal hoop 14 and lower metal hoop 16. Microprocessor controller 202 may be any computing device such as but not limited to a System On Chip single board computer, a smart phone, or a Personal Digital Assistant, computing tablet, laptop computer or desktop computer with wireless capability via any wireless protocol such as but not limited to WIFI, Bluetooth, or any proprietary wireless protocol capable of connecting to a System On Chip single board computer, a smart phone, or a Personal Digital Assistant, computing tablet, laptop computer or desktop computer. Microprocessor controller 202 executes software programs consisting of an operating system and software algorithms that perform the calibration and tuning functions of the system. The number of auto tuner devices may vary depending on the size and configuration of the drum. FIG. 4 depicts Microprocessor Controller communicable coupled to auto tune device 208 through auto tune device 214 via a wireless communications link received via antennas 216. The amount of current being used by any of the auto tune devices 208 through 214 is monitored by an auto tune device's electrical current sensing device 218. Electrical current sensing device 218 contains the electrical current monitoring circuitry and the necessary electronic circuitry for communicating over the wireless link to microprocessor controller 202 via antennas 216. Electrical current sensing device 218 sends a signal to microprocessor controller 202 that is an indication of the amount of current being used by any of the auto tune devices. The electrical current driving any of the auto tune devices is proportional to the amount of torque being created when stepping motor 102 is being actively stepped under control of microprocessor controller 202 via the wireless link. The algorithms used to control microprocessor controller 202 are detailed in FIGS. 5, 6, and 7. Microprocessor controller 202 receives signals from electronic module 218 indicating the amount of electrical current being supplied to each auto tune device 1-‘n’. The level of electrical current delivered to each auto-tune device 208-214 as monitored by electrical current sensing device 218 and is saved in drum tuner database 400 (FIG. 8). The algorithms used to control microprocessor controller 202 are detailed in FIGS. 5, 6, and 7.
Now referencing FIG. 5 where 250 depicts a control algorithm used to initially calibrate a drum using the drum auto tune devices illustrated in FIGS. 1-4. Drum calibration sequence flow starts at process entry 252 calibrate then advances to process block 254. Process block 254 scans the hard-wired bus 206 in one embodiment or the wireless link supported by antennas 216 (FIG. 4). Each auto tune device 208-214 in FIG. 3 is individually addressed over communications bus 206. If a wireless embodiment is being described, as in FIG. 4 electronic module 218 attached or residing in each auto tune device communicates with Microprocessor controller 202 via a wireless protocol and antennas 216. In the wireless embodiment, electronic module 218 is individually addressed through the wireless protocol. Process block 256 initializes tuned database 400 to a default state where after control falls through to process block 258 which sets an index to the first entry into database 400 (FIG. 9) where after control falls through to process block 260. Process block 260 commands the stepper motor for auto tune device corresponding to the tuned database entry[index] and is commanded to rotate in the unload direction a predetermined number of steps while the drive current is being monitored after which control falls through to process block 262. Process block 262 compares the monitored drive current for the currently commanded auto tune device against the tuned database 400 entry[index].free run current. If the monitored drive current is equal to or less than tuned database 400 entry[index].free run current, control falls through to process block 264 else control is passed to process block 260 where that process block is repeated. If control fell through to process block 264, the index is incremented to the next entry in tuned database 400 after which control falls through to process block 266. If the value of the incremented index is greater than the last entry in tuned database 400, control falls through to process block 268 else control is passed to process block 260 where that process is repeated for the current auto tune device associated to the current entry in tuned database 400. If control fell through to process block 268, the index is set to the first entry into database 400 where after control falls through to process block 270. Process block 270 commands the stepper motor for auto tune device corresponding to the tuned database entry[index] to rotate in the load direction a predetermined number of steps while the drive current is being monitored after which control falls through to process block 272. Process block 272 compares the monitored drive current for the currently commanded auto tune device against the tuned database 400 entry[index].free run current. If the monitored drive current is greater than the tuned database 400 entry[index].free run current, control falls through to process block 274 else control is passed to process block 270 where that process block is repeated. If control fell through to process block 274, the index is incremented to the next entry in tuned database 400 after which control falls through to process block 276. Process block 276 determines if the value of the incremented index is greater than the last entry in tuned database 400 and if it is, control falls through to process block 278 else control is passed to process block 270 where that process is repeated. If control fell through to process block 278, the index into tuned database 400 is set to the first entry after which control falls through to process block 280. Process block 280 commands the stepper motor for auto tune device corresponding to the tuned database entry[index] to rotate in the load direction a predetermined number of steps while the drive current is being monitored after which control falls through to process block 282. Process block 282 compares the monitored drive current for the currently commanded auto tune device against the tuned database 400 entry[index].tuned drive current. If the monitored drive current is greater than or equal to tuned database 400 entry[index].tuned drive current, control falls through to process block 284 else control is passed to process block 280 where that process block is repeated. If control fell through to process block 284, the index is incremented to the next entry in tuned database 400 after which control falls through to process block 286. Process block 286 determines if the value of the incremented index is greater than the last entry in tuned database 400. If the value of the incremented index is greater than the last entry in tuned database 400, control falls through to process block 288 else control is passed to process block 280 where that process is repeated. If control fell through to process block 288, the calibration for all auto tune devices is completed and the drum calibration sequence algorithm exits.
Now referencing FIG. 6 where 300 depicts a control algorithm used to tune a drum during a performance using drum auto tune devices illustrated in FIGS. 1-4. Drum performance sequence algorithm flow starts at process entry 302 performance tune. This algorithm ensures that while a drummer is aggressively striking the drumming surface of the drum and causing the drumming surface to stretch and thus go slightly to greatly out of tune during the performance, the drum will be constantly brought back into tune while the instrument is being actively played. Once the algorithm is entered through process block 300, control falls through to processing block 304 where the index is set to the first entry into database 400 where after control falls through to process block 306. Process block 306 commands the stepper motor for the auto tune device corresponding to the tuned database entry[index] to rotate in the load direction a predetermined number of steps while the drive current is being monitored after which control falls through to process block 308. Process block 308 compares the monitored drive current for the currently commanded auto tune device against the tuned database 400 entry[index].calibrated drive current. If the monitored drive current is greater than or equal to the tuned database 400 entry[index].calibrated drive current, control falls through to process block 310 else control is passed to process block 306 where that process block is repeated. If control fell through to process block 310, the index is incremented to the next entry in tuned database 400 after which control falls through to process block 312. Process block 312 determines if the value of the incremented index is greater than the last entry in tuned database 400. If the value of the incremented index is greater than the last entry in tuned database 400, control falls through to process block 314 else control is passed to process block 308 where that process is repeated. If control fell through to process block 314, the performance tune for all the auto tune devices is completed and the performance tune sequence algorithm exits.
Now referencing FIG. 7 where 350 depicts an algorithm that, while a drum is actively being played, a timer interval is set and when it expires, a performance tune algorithm 300 will be called (FIG. 6). Performance algorithm 300 when executed will retune the auto tune devices 208-214 (FIGS. 2 and 3) then will exit back to timed tune 350 where that algorithm is repeated until the algorithm is exited at the end of the performance. When timed tune 350 is started, entry into the algorithm is via process block 352 where control falls through to process block 354 where the timer interval is set. This interval may be relatively short for a performance where the drum is aggressively played to a relatively long interval where the drum is only occasionally played. For example, a heavy metal rock band using fast drumming may have the interval set to a few seconds whereas a classical symphony may have the interval for a kettle drum set to a minute or more. After the interval is set control falls through to process block 356 where the interval timer is started after which control falls through to process block 358. Process block 358 checks the interval timer and if the timer has not expired, control will be returned to process block 358. If the interval timer has expired, control will fall through to process block 360. Process block 360 calls process block 300 performance tune entry. After the called performance tune 300 returns, control falls through to process block 362 continue timed tune. If the performance is not finished, control will be passed to process block 356 start interval timer where the process is repeated. If the performance is finished, control will fall through to process block 364 which exits the timed tune algorithm 350.
Now referencing FIG. 8 where a portable embodiment of the instant invention is described. FIG. 8 depicts a snare drum 12 with an upper metal hoop 14 and a lower metal hoop 16. Each of the metal hoops secures a drum surface to the snare drum cylinder 12. In this depiction only one of a plurality of tension rod assemblies are shown consisting of tension rod body 32 with tension rods 26 threaded into tension rod body 32. Each tension rod 26 passes through a flange 28 attached to or is part of upper metal hoop 14 or bottom metal hoop 16. A tension nut 30 is threaded onto each tension rod and bares onto flange 28 which pulls upper metal hoop 14 or lower metal hoop 16 toward the center of snare drum cylinder 12. Tension nut 30 is normally tightened by the person who tunes the drum. In this embodiment, a drum auto tuner device 100 is mounted onto the rim and the outside of upper metal hoop 14 and lower metal hoop 16. Now referencing FIG. 2 where 100 depicts the drum auto tuner device composed of stepper motor 102, gear transfer enclosure 104 and gear reduction device 106. As stepper motor 102 is driven by microprocessor controller 202, (not shown) stepper motor 102 turns and transfers torque through gear transfer enclosure 104 to gear reduction device 106. Gear reduction device 106 multiplies the torque provided by stepper motor 102 through gear transfer enclosure 104. The revolutions per minute speed of stepper motor 102 is reduced by gear reduction device 106 which in turn increases the torque to tension assembly 108, 110, and 112. Tension assembly 108, 110, and 112 is composed of threaded drive screw 108 which in turn pulls or pushes threaded tension tube 110 toward upper or lower metal hoops 14 or 16. In this embodiment, threaded tension tube 110 is replaced with alternate threaded tension tube 116. Alternate threaded tube 116 is fixed on threaded drive screw 108 with jam nut 118. Alternate threaded tube contains a slotted cut 120 that fits onto tension rod fixture 30. In present embodiment, tension rod fixture 30 fits into alternate threaded tension tube 116 slotted end 120. When auto tune device 100 rotates threaded drive screw 108, tension rod fixture 30 rotates pulling upper metal hoop 14 or lower metal hoop 16 toward the center of snare drum cylinder 12 or loosens upper metal hoop 14 or lower metal hoop 16 removing tension on the drum surface.
Now referencing FIG. 9 where 400 depicts tuned database 400. Tuned database 400 contains entry 402 Number Of Devices. This entry is the number of autotune device for the drum the invention is currently operating on. Each autotune device mounted on said drum has a record in tuned database 400. Record entries 404-408 contain record entries 410 through 414. Record entry 410 free run current is the electrical current consumed by stepper motor 102 when of auto tune device 100 is not encountering resistance loading via gear transfer device 103 communicably coupled to gear reduction assembly 106. Record entry 412 is the amount of level of electrical current used by auto tune device 100 when drum tuner device was initially calibrated. Record entry 414 is the level of electrical current used by auto tune device 100 when the drum was brought into tune.
