Description

The invention of the present application is a new golf club for practice, particularly a golf club that can easily know the hit position at the face of the club head, and is provided with a number of pipes and / or flat plates on the back face of the face. The present invention relates to a method for manufacturing a plurality of vibration wave sensors (hereinafter often referred to as sensors) having a special calculation unit in a golf club.

For a long time, as a practice golf club, to learn the striking stress, striking angle, and ball striking position (where the ball hits the face of the club head) It was a serious concern for people.

Therefore, some kind of sensor (sensor = abstract noun “sensing element”), other abstract noun transducers (elements that convert physical quantities into electrical signals, in a broad sense, one energy form to another energy form) It has been in conversations as a wishful expression exchanged by golf friends for a long time to see where they hit it with a display (monitor) etc.

In other words, these were long-awaited desires, but were not commercialized. Accordingly, the specific means is not clarified, and only a golf club with a sensor and a display is abstractly desired and not an invention. However, since there is no specific technology or method to actualize this desire at all, there are many trials and proposals, but in a substantial sense, it has long been left unsolved and not put into practical use. .

In addition to the desire, what kind of actual function sensor is placed where, how, what signal is processed so that it can be taken at what timing, how it is processed, what display form, figure There was no disclosure of the contents based on specific experiments, such as where, how and how they were displayed, and whether or not they were correctly processed by experiments.

On the other hand, although it is a reliable method, taking pictures with a high-speed camera is expensive and expensive, and requires a bright light in relation to the sensitivity with a short shutter time. The shot must be taken from the front, the shot must be taken from the front, and the ball will fly from the front, so the photographer is extremely dangerous and has serious flaws such as protection to prevent breaking the camera. It was.

As far as the present inventor is aware, what has been realized is a paper on the market in which pressure-sensitive color-changing paper is pasted on the head and the ball is hit by the color change of the paper. This has serious problems such as repeated troublesomeness that paper has to be applied to and peeled off from the face of the club, and that the feeling of impact differs depending on the paper.

So far, the Evans patents (patent documents 1, 2 and 3) have long been equipped with an accelerometer on the golf club head, a bending stress meter and a strain meter on the shaft, and a monitor (display device) : In particular, there is a suggestion that the oscilloscope describes). In addition, an attempt to display is shown in contrast to those in a continuous swing, but the portion of the face that has been hit has not been successfully displayed. It is recognized that these patents have already cited and referred to many previous patents, and have had the above-mentioned desire for a long time.

In Hammond's US Patent (Patent Document 4), an accelerometer is placed in three directions perpendicular to the head, and the hit point data signal is compared with the actual signal to estimate where the face hit. However, it is not shown in detail, and the ball has strength, rotation, ball type / manufacturer difference, wetness difference, dirt difference, temperature difference, etc. Not enough.

Pharma's U.S. Patent (Patent Document 5) describes a liquid crystal display (LCD) from a graph showing the relationship between the acceleration attenuation and the preliminary test result of the flight distance according to the impact value obtained through one acceleration sensor (transducer). ) And light-emitting diodes (LEDs) are proposed, but they are not hitting positions.

According to Igarashi's US Patent (Patent Document 6), “a head having an effective striking range” is disclosed in which a hollow is provided in a golf club head, filled with urethane foam, and displayed on a place such as a CRT (CRT) using a transducer. A method of “designing” has been proposed. Certainly, it would be better if the sweet spot of the head was wide. Again, the location of the strike is not shown in detail.

The Dekai patent (Patent Document 7) discloses one means for determining the position where the sound is generated from the sound in the structure. However, hitting position specification by golf sound has not been successful.

In Yasuda et al. (Patent Document 8), a magnetic sensor is placed under a place where a ball is set at a place where a shooting practice is performed, and a magnetic signal generated by the movement of a metal due to a swing is analyzed. Methods have been proposed for measuring speed, swing trajectory, face angle, and the like.

This requires a fixed mechanism under the hit ball to be hit, depends on many different types of clubs, makes it difficult to clarify the respective hit point position data, and the installation of such a mechanism is too large and not convenient. No matter where the goal is, it can not be considered that the hit position has been successfully identified. It is not a club but a specific place outside of the club.

A US patent (Patent Document 9) of Kustanovich proposes a method in which a selective conductive electrode layer and a pressure-sensitive impedance layer are arranged concentrically to determine the force and position of impact. Although it is said that it can be used for pitching practice of baseball pitchers and sports such as golf, the impact at the time of hitting golf is surprisingly high pressure, and if it is placed outside it is not durable, etc. In addition, there was a serious defect such that the impact could be considered blurry due to the face inside. In particular, it has been unsuccessful in specifying the correct spot location.

In Sakamoto's patent application (Patent Document 10), a concept is shown in which a pressure sensor is attached to a golf club, and information about the ball is appropriately displayed at a location / part by a microcomputer. In particular, it is also described that the impact force value is measured and displayed by a “pressure” sensor fixed to the lower part of the shaft. This is similar to Evans' US patent. There is little explanation about the hitting position and it is not clear.

According to Putt's US Patent (Patent Document 11), the putter is detachable (embedded in wood), and the transducer is placed on the face (also referred to as a face). If the ball is directly touched, it has a serious defect in that it cannot withstand the surprising impact value (estimated to be 1 ton / square centimeter). Furthermore, the values are front and back, that is, only toe and heel (the patent has a figure like a piano keyboard, so you can see front and back [front side or front side] but up and down [sole or ground side] The crown, or the top side is impossible.) The vertical direction is unknown, and the hitting position has not been specified successfully.

The Wilhelm patent (Patent Document 12) discloses a golf swing evaluation system that displays the maximum striking force and the striking position on a display unit. Have taken. As a specific example, the arrangement of a piezoelectric sensor (pressure sensor) is disclosed, and means for analyzing from the relationship between voltage and time is also disclosed. It is also disclosed that a display portion is provided on a wrist like the wristwatch at the other end of the grip. From the point of view of durability and accuracy, there is no specific disclosure of the calculation to determine the position, and it is hopeful and cannot yet be considered as achieved.

In Watanabe's device (Patent Document 13), the above-mentioned various desires are described, and more specifically, there are contacts from the face surface to the inner surface of the golf club, and a large number of contact units provided on the inner surface. (Rubber) is provided, and when the ball hits, there is a disclosure in which the contact is pushed and energized, the position is detected, and the result is displayed on the display device. It is unknown and the contact method, so there are still problems with durability, weight, and difficulty in manufacturing. It is necessary to provide a large number of contacts from the outside to the inside.

In the Gedni patent (Patent Document 14), the basic concept of the Sakamoto patent and the Wilhelm patent are used to analyze using the peak value of the impact force or the extension force. It is described that the impact force is detected by a plurality of sensors provided on the head, and the impact force and the rotational movement direction of the sphere (corresponding to a slice or a hook) are mainly displayed. Because the emphasis is placed on the former, the description of the location of the hitting point is not clear.

The Marsh patent (Patent Document 15) describes that a piezoelectric film composed of a plurality of sensor elements is bonded to a face and that the piezoelectric sensor elements are arranged in an orthogonal arrangement, an eccentric circular pattern, or the like. However, the hitting position determining means (including calculation) is not clear.

In the Suzuki et al. Patent (Patent Document 16), a plurality of detection means such as an impact sensor for detecting the hit position of the ball is provided on the head, and a flying distance is estimated, a liquid crystal display method for displaying the hit position, a lighting display method, etc. It is described that the desire to provide the display means on the shaft portion and the understanding of the flight distance of the ball depending on the hit position.

Assuming that there is no problem in installing the head on the surface of the metal plate, considering that there is no installation, how to detect and calculate the installation on the back of the metal plate because the impact pressure is applied to the entire metal plate Is unknown, that is, the desire is stopped, and since various sensors with different properties are enumerated, the feeling of the application for the application is further reduced.

In the family's patent (Patent Document 17), a sound analysis is used that makes use of the feature of concentric sensors.

However, in the conventional technology, there is an abstract noun that everyone can easily think of (1) “sensors” and (2) “lists of desired items” for ordinary people who want to “display”. The means to substantially resolve the desire for “detailed specification” of the “striking position” is not specifically described, and a complete technology that can withstand practical use is not disclosed, and the system is simple However, there is a serious drawback that it cannot withstand the impact value at the time of impact, and that the judgment is ambiguous and it becomes substantially heavy.

For example, the former says "I want to go to Mars with a vehicle (= spacecraft), but there are many things that are equivalent to patents being applied for as a" spacecraft with a function to go to Mars ", although it is just a list of wishes. . There is no detailed calculation method, actualized technology, or example of how to deal with what signal and how the hitting position can be really determined, and the specific position has been successfully identified (the invention has been completed). Can't be seen. For this reason, the present inventors have not yet found a completed product in the market.

Although the specific achievement means / technology must be patented, a claim for aspirational expression or abstract expression is described, and this expanded concept is judged to be publicly known, which has a negative effect on many technological advances. Has occurred. In particular, with respect to the hitting position specifying means on the golf club face, it can be considered that the desire means has been misunderstood as a problem solving technique.

In addition, the above has not yet been put on the market, it is difficult to implement or it is difficult to clearly determine the hit position, or it breaks immediately, it is too heavy, the appearance is abnormal, production is difficult, etc. It seems that there was a serious defect.

In addition, PVDF (polyvinylidene fluoride) piezoelectric element (transducer) has (1) a hard metal plate on the surface of the hitting part of the head, and (2) the outer peripheral part being fixed (various boundary conditions) (3) Because the face part is not a flat surface but a convexly curved surface, it is unclear what vibration, where it is, and how it vibrates, infinitely It is completely different from the open board (there is a boundary condition), the electromotive force is small, it is fragile or deformed, and it is completely unknown how to process the received value. There were drawbacks such as lack of proof of localization.

  In general, a method of detecting a direct sensor response by providing a large number of piezoelectric sensors in order to determine the hit point position on the entire face surface has been the mainstream. The need for a large number of sensors was also the biggest drawback.

An object of the present invention is to specifically provide a practical technique that can be industrialized without the above-mentioned various defects. In addition, it provides a means of satisfying many trade-off issues at the same time while improving the various disadvantages that are considered to have not been solved yet, especially the biggest issues of light weight, accuracy and durability. For the purpose.

This type of trade-off (bilateral / multiple) is not clarified or solved in the known literature. Therefore, an invention that can be put into the market (that can be embodied) must be provided.

The main problems to be solved are as follows, and other objects will be clarified in the detailed description below. That is, it is to improve the unsatisfied part of the conventional proposal so as to meet the reality dramatically.
(1) The number of sensors is minimal, light, and reduces the probability of breakage.
(2) The contact position is displayed substantially correctly and has been proved and confirmed.

(3) Capturing the moment of striking (not the data when swinging up or after hitting),
(4) There is a true disclosure of what means and calculation determined the hitting position,
(5) Light weight (light weight, power supply included)
▲ 5 ▼ Can be small (contains in the head)

(6) Withstand repeated impacts (durability)
(7) The position can be displayed correctly within the range of practical accuracy (accuracy).
(8) Low power consumption (electric power)

▲ 10 ▼ Not complicated (things that can be manufactured)
▲ 10 ▼ Do not put a burden on the user in operation (easy care, easy viewing, easy handling, resetability, quick response)

▲ 11 ▼ Good workmanship, at least not unsightly (allowing for higher sensitivity perspective)
(12) Small number of detectors (weight, manufacturability)
(13) There is no need to install a special device outside, that is, on the ground side. (14) The result is easy to see.
▲ 15 ▼ Can save electricity,

(16) The purpose is to solve comprehensive items such as that the missed results can be restored, in a balanced manner. In particular, it is to provide means for answering problems that can be industrially implemented.

  The gist of the present invention is as follows.

That is, the back (back) of the golf club's striking surface (face surface) is provided with a plurality or multiple pipes of substantially different length, thickness, hole diameter, and material between 5 mm and 3.5 mm, or / And a sensor that captures each of these different vibration waves according to the difference in the striking position, and a plurality of flat plates of substantially different width, thickness, length between 5 mm to 3.5 mm and different materials are provided. A microcomputer unit with an arithmetic function software circuit that analyzes the vibration waveform and specifies the hitting position and calculates the hitting position, and the approximate outline of the face and the hitting position are simultaneously displayed. A hitting position detecting golf club characterized in that a display unit and a power source unit are attached at the same time.

Pipes with substantially different lengths, thicknesses, and hole diameters between 5 mm and 4.5 mm, and flat plates with substantially different widths, thicknesses, and lengths between 5 mm and 4.5 mm are generally described as “acoustic protrusions”. Or “pronunciation”.

A plurality or a plurality of pipes having substantially different lengths, thicknesses, and hole diameters between 5 mm and 4.5 mm are provided on the back (back) of the striking surface (face surface) of the golf club, and / or substantially Provide a plurality of flat plates with different widths, thicknesses, and lengths between 5 mm and 4.5 mm, and provide sensors for capturing these different vibration waves depending on the striking position (inside the head or in the shaft). A microcomputer part with a calculation function software circuit that analyzes the vibration waveform and identifies the striking position substantially and calculates the striking position, and the approximate contour of the face and the striking position at the same time It is a manufacturing method of a hitting position detection golf club characterized by including the method of providing a display part and a power supply part to display simultaneously.

The basic technical idea will be described in detail. It can be said that the point (secret) lies in the installation of a pipe and a flat plate (also referred to as a metallic ximen shape) on the back face of the club head face. Moreover, it can be said that it is a secret to arrange pipes or flat plates of different lengths sequentially. As you can see from the flute, pipes of different lengths have different natural frequencies.

In addition, small strips with different lengths (also referred to as “ximen”) are easy to understand if reminiscent of harmonica reeds. Each natural frequency is different.

As a superordinate concept, “acoustic protrusions” or “pronunciation protrusions” should be associated with whistles, flutes, and shakuhachi. On the other hand, it is easy to understand if associated with the leads of harmonica, organ, and accordion.

It can be said that the more directly behind the pipe, the longer the vibration becomes, and the farther away the pipe, the larger the corresponding natural vibration. Therefore, the center of hitting is clarified by analyzing many provided sounds as to where is the center of hitting. It is impossible to specify the position of the sound without any pipe or ximene-like flat plate, but surprisingly, in the present invention, it is surprising that the length of the pipe on the back of the face and / or the plate-like protrusion is set differently. This made it possible to determine for the first time where the ball was hit by sound analysis.

By striking various parts with a hammer with a ball divided into strengths, it is possible to know what kind of sound (vibration) will be emitted when it is struck, and a large number of simulated data corresponding to the actual impact can be obtained. In addition, with the hitting machine, it is possible to verify by the location data where the hitting point is set in advance and the analysis of the hitting position and vibration (sound) where the pressure-sensitive discolored paper is actually applied to the face, and the relationship between the hitting position and the sound Became clearer.

In addition to these judgment methods, correctness can be analyzed in advance by computer analysis. Regarding these, the calculation results will be shown in the figure later.

For ease of understanding, a diagram is drawn with the help of a computer (PC). FIG. 1 shows the internal structure of the driver, in which different pipes and different flat plates are arranged in two rows in an orderly manner. FIG. 2 shows the striking position for the arrangement.

There are 4 rows in total. 6 and 11 for the “Top”, FIGS. 7 and 12 for the “Bottom”, FIGS. 3 and 8 for the “Center”, and FIGS. 4 and 9 for the “Far”. 5 and FIG. 10, the vertical axis represents acceleration / force (FRF) and the horizontal axis represents frequency (Hz). The former is logarithmic display and the latter is linear display. This makes it easy to see the response level.

For example, since the feature corresponds to the hitting position, the hitting position can be determined. That is, the characteristics of the pipe and the diaphragm can be understood. This means that the hitting position is known. The hitting position is determined by listening to the so-called whistle and harmonica. The striking position can be determined based on which strong vibration is generated.

[FIG. 1] is a club head figure drawn to help understanding of the present invention.
FIG. 2 is a diagram showing a face corresponding to a hit. Five points of Far, Center, Near, Top, and Bottom are shown.

[FIG. 3] is a diagram showing the impact vibrations at five locations when the Center portion is hit, with the vertical axis representing acceleration / force (FRF) and the horizontal axis representing frequency (Hz). FRF is Newton divided by the square of meters / second. ** 2 means square. Also, on a logarithmic scale, 1.0E + 05 is 1.0 × 10 5.

E is E in the meaning of “Exponential”. The vertical axis is a logarithmic scale. Hereinafter, all of the graphs up to FIG. 8 to 11 need to be noted because the units of the scale are different. FRF is “Frequency Response Function, ie, vibration transfer function, frequency response function”.

[FIG. 4] is a diagram showing the impact vibrations at five locations when the Far portion is hit, with the vertical axis representing acceleration / force (FRF) and the horizontal axis representing frequency (Hz).
[FIG. 5] is a diagram showing the impact vibration at five locations when the Near portion is hit, with the vertical axis representing acceleration / force (FRF) and the horizontal axis representing frequency (Hz).

[FIG. 6] is a diagram showing the impact vibrations at five locations when the top portion is hit, with the vertical axis representing acceleration / force (FRF) and the horizontal axis representing frequency (Hz). From now on, all figures are based on the assumption that the striking position is taken.
[FIG. 7] is a diagram showing the impact vibration at five locations when the bottom part is hit, the vertical axis representing acceleration / force (FRF), and the horizontal axis representing frequency (Hz).

[FIG. 8] is a diagram showing the impact vibration at five locations when the Center portion is hit, the vertical axis representing acceleration / force (FRF), and the horizontal axis representing frequency (Hz).
[FIG. 9] is a diagram showing the impact vibrations at five locations when the Far portion is hit, with the vertical axis representing acceleration / force (FRF) and the horizontal axis representing frequency (Hz).
[FIG. 10] FIG. 10 is a diagram showing five impact vibrations when hitting the Near part, where the vertical axis represents acceleration / force (FRF) and the horizontal axis represents frequency (Hz).

[FIG. 11] is a diagram showing the impact vibration at five locations when the top portion is struck, the vertical axis representing acceleration / force (FRF), and the horizontal axis representing frequency (Hz).
[FIG. 12] is a diagram showing the impact vibration at five locations when hitting the bottom part, the vertical axis is acceleration / force (FRF), and the horizontal axis is frequency (Hz).

As shown in FIGS. 8 to 12, the characteristic peaks are displayed by changing the scale display of the vertical axis. Since these are different from each other, it is indicated that the hit point can be determined.

If a similar peak appears, it is impossible to distinguish. A peak appears at a certain vibration corresponding to the strongest spot.

It is preferable that a flat plate such as a pipe such as a whistle, a harmonica, an organ, or an accordion lead (vibration plate: rectangular) emits a unique vibration sound different from the adjacent pipe or the adjacent flat plate.

The “preferable arrangement” may be a random arrangement, but is preferably an orderly arrangement of different lengths. Although the description has been given for “length”, the same applies to “thickness”, “thickness”, and the like. The secret is to avoid the adjacent resonance as much as possible. A horizontal hole may be provided in the pipe or the flat plate. The whistle can be easily understood because the sound can be changed by closing or opening the side holes.

These pipes and flat plates can be defined as "acoustic protrusions" or "sounding protrusions" when collectively referred to by a superordinate concept. A sounding body other than a preferable pipe or flat plate is attached, and it cannot be said that it is not right. If it is a superordinate concept “acoustic protrusion” or “pronunciation protrusion”, all are included. A side hole can be said to be substantially equivalent to a length change.

In the present invention, there is provided a swing speed measuring unit or an acceleration sensor measuring unit, and has a calculation unit that activates a timer unit for time difference measurement when the swing speed or acceleration exceeds a set value. It also includes a club for position detection practice.

Normally, at the start of measurement, a timer is started and a switch for setting the initial state of the electronic circuit is required. This addition makes it very convenient. Moreover, it also saves power.

Any sensor may be used as long as it can detect the time immediately before hitting. For example, a torsion sensor attached to the shaft (distortion sensor, distortion increases with acceleration immediately before hitting), a club head position detection sensor (when it is close to the ground, it is determined immediately before hitting), or the like may be used. It can be turned on for a certain period of time when it is moved and turned off if it is not moved for a certain period of time.

Some people send golf club bags directly from one country club to the next. Therefore, many people forget the battery. In order to avoid this, it is extremely important to eliminate the need for a battery or extend the life of the battery.

Recently, in response to the rapid performance improvement of the light-receiving power generation film, a battery can be eliminated by winding or sticking a solar cell (many films) around the surface of the club shaft. Since golf is performed in a bright place, a light source is easily secured.

Further, as another additional function in the present invention, a power-saving type capable of detecting a striking position, characterized by having a sensor unit that makes a measurement state by swinging a club and a reset button unit that restores the disappeared image Includes practice clubs.

It is preferable that when the club is shaken, an acceleration sensor or the like provided in the club detects the swing and the previous display screen is turned off to enter a measurement state. By doing so, it is possible to automatically enter a measurement state without pressing a switch or the like.

But sometimes you want to see the previous state. It was not until I tested this club that I accidentally shook it. At that time, it includes one provided with a memory part so that the screen can be returned to its original state by pressing the reset button.

In addition, since there are words such as acceleration sensor and impact sensor in the above-described known examples, there is a possibility that the main part of the present invention is misunderstood as the same usage, but the essence of the technical idea is It should be noted that paper should be distinguished.

In the present invention, a vibration sensor unit that captures at least sound emitted from the projections on the back surface of the face portion of the golf club or in the shaft, a microcomputer unit that substantially calculates the striking position, and further display A golf club having both a power supply unit and a power supply unit, and further, the display unit substantially displays the center of the hitting ball with respect to the outer shape of the face part of the golf club or an approximate face figure. Alternatively, the hitting position detection is characterized in that at least one selected from “ten” cross display, “×” × display, or “○”, “●”, “◎” circle display is used as the display unit. Includes possible practice clubs.

A combination of these may also be used. Many have found that a small display part that does not get in the way is provided near the grip of the shaft, so it must be very easy to understand and is extremely important.

The present invention also includes a practice club capable of detecting a striking position, characterized in that the striking position display according to the present invention includes a display unit having a function of “flashing” the display and the sign. It was also found that the flashing changed dramatically in spite of the small display area. In addition, when the color is red (when color is displayed), the discrimination performance is easy to understand (easy to see) regardless of whether it is flashing or not.

In the present invention, as described above, the club shaft or the head has at least a part covered with a power generation material, and the sensor or the sensor power supply or the connection for supplying the display power supply It also includes a club for practicing hitting position detection with a power generation function, characterized in that These are achieved by winding the upper surface of the club head or the shaft.

There are times when you want to process the person's habits and data statistically, or analyze statistics. At that time, it is necessary to transfer the data to another device, such as a mobile phone, mobile personal computer, or wristwatch type microcomputer in a broad sense. In clubs, the accumulation of large volumes of data is undesirable because it increases weight and is preferably transferred to a nearby device. This can be transferred by radio or RFID (abbreviation for Radio Frequency Identification).

This purpose can be said to be a power-saving type and a lightweight type. Although a swing speed measuring unit or an acceleration sensor measuring unit is provided, since this type of sensor is already on the market, it exerts a great effect by docking with the product of the present invention.

In the test prior to the present invention, vertical and horizontal numbers / symbols / symbols are provided on the face drawing created separately to indicate the hit point positions. First of all, a method of knowing the location of the hitting point was conceived by comparing the sign with the sign of the face drawing with the sign at hand when displayed on a small monitor.

Although this method has a serious defect that must be compared one by one, on the other hand, the monitor (LED, liquid crystal, plasma, organic) can be made very small, so it can be manufactured inexpensively and without obstructing. There is.

If the face is numbered horizontally with Arabic numerals 1, 2, 3, 4, 5,..., The letters “A”, “I”, “U”, “E” and “O” are added vertically, and “1 a” is displayed again. Then, because it is on the front direction, this person will say that there is a “1”. However, it is not interesting and inconvenient to bring the table separately.

In order to display where it was hit, it is very important to display the face outline on the monitor part by displaying the outline of the face part and where it was hit. It is very easy to understand if it is displayed by approximating the face part outline display or inverted trapezoid.

In addition, in the present invention, it is possible to receive power from a transmitting antenna provided in a club and transmit the sensed information simply by bringing it closer to a display device with a receiving antenna provided separately or a wristwatch type display unit. It also includes a club for practicing hitting position detection, characterized in that it is a set with a receiving unit to be processed.

The present invention can be displayed very accurately, except for the exceptions described above, even by a test with a hitting robot, a test with a hitting hammer, and a large number of tests with a discoloration hitting position recognition sheet. ,It could be confirmed.

In the present invention, it is important in a psychological sense to blink and inform the LED when entering the measurement state. Such a mechanism may be used. Talk to "Nice Shot" or "Prince of the Star" when you are in a good hitting position, and you can have pronunciation and remarks such as sounding music and encouragement when it is not good. By renting this cheap machine, you can put an advertisement in this call. This promotion method can also be used to popularize this kind of equipment. However, if it becomes heavy, there is a risk of losing its original purpose.

1) Succeeded in clarifying the hit ball position. In short, it made it possible.
2) It was confirmed by numerous hit results.
3) Since it was confirmed by a number of hitting results, the reliability is high.
4) We succeeded in display without using too complicated sensors.
5) Surprisingly, the durability was improved.

6) The effect that the variation in data could be reduced was obtained.
7) We succeeded in reducing weight.
8) The striking sound changes due to the vibration of the pipe and the flat plate, but this is not a fault, but rather a fun sound. Some people with good ears and heads may know where they hit after repeated many times without relying on the instrument.

The following examples illustrate the invention in more detail. However, this example does not limit the effectiveness of the present invention.

As a round bar, diameter φ3, thickness 1mm, length 5, 8, 11, 14, 17mm each, two rows of metal titanium alloys of 20, 23, 26, 29, 32mm back, flat plate is also 3mm wide Thickness is 1mm, length is 5,8,11,14,17mm each, returning to 20,23,26,29,32mm, gap is 5mm, bonding method is welding (TIG welding) I went there.

I picked up the vibration with the microphone. The impact test was conducted with an impulse hammer (GK-3100ONO SOKKI manufactured by Ono Sokki). Measurement was performed with an FFT analyzer (analyzer CF5220 manufactured by Ono Sokki). As a result, the hit point position could be measured. In addition, a pressure-sensitive test paper was attached to the face just in case, and verification was performed by comparing the striking point and the color change. All the results were surprisingly correct.

(Comparative Example 1) When no pipe or flat plate was provided on the back of the face, no characteristic peak vibration appeared even when the center, top and bottom, and front and rear five hit points were hit with an impulse hammer. For this reason, the hit point position could not be specified.

(Changeable range) First, a sensor that captures vibration noise may be provided inside the head, but since sound (air vibration) is transmitted from the head through a hole in the shaft, it is close to a grip with less impact destruction. It is preferable to provide it at a place. Thereby, the life of this electrified club can be dramatically extended. The sound wave inside the shaft is extremely attenuated. The sound transmission in the pipe can be better understood by looking at the doctor's stethoscope. It is an important technique as claimed. Surprisingly, it has been found that a sensor may be mounted outside the shaft. You may provide a hole in the side wall of a shaft. It also includes a technology that collects sound in a trumpet toward the sensor.

There are many sensors that one skilled in the art can choose. An ultra-small capacitive condenser microphone is sufficient. For example, the diameter was about 2 mm and thickness 4 mm. The length of the pipe or flat plate (also referred to as a short type or a lead type) is particularly preferably within a range of 10 mm to 30 mm. As the “vibration material”, pipes such as whistle, and flat materials such as harmonica reeds, each of which produces a specific vibration sound are preferable. A person skilled in the art can appropriately select a material. If these are provided with a lateral hole and the length is the same, it is not allowed to escape.

Regarding the “fixing method” and “adhesion method”, it is extremely important to prevent them from coming off with a strong blow. Any of welding, bonding, and screwing may be used. Preferably, when the face has a multiple structure, screwing is good. For the “vibration measurement”, various microphones are preferable, but other means may be used as long as they can withstand hitting. A small vibration sensor is preferred. Particularly preferably, it is made at once by casting. This eliminates the need for welding, bonding, and screwing.

It is already known to provide a sound collection sensor, a microphone, and the like in the club head. It is also known that the lead wire is passed through the shaft and transmitted to a monitor (also referred to as a display unit or monitor) provided in the calculation function unit near the grip to display the calculation. It is also known that mathematics for computation is not covered by a patent.

The present invention is particularly useful for the golf club manufacturing industry and the sports equipment manufacturing industry. It can also be used as a tool verification device.
