Summary of the Invention

Problems to be Solved by the Invention

[0004] In the case of a golf club with a hosel, the vibrations generated in the club head when the golf ball is struck are transmitted through the shaft to the user's (golfer's) palm as they grip the club, and are perceived as part of the feel of the club. On the other hand, the hosel, which is interposed between the shaft and the head, can act to hinder the transmission of such vibrations. Therefore, golf clubs with hosels have the challenge of making it more difficult to achieve a good feel compared to golf clubs without hosels. The term "feel" refers to the sensation or shot feel that the user experiences when striking the golf ball. Generally, the feel of a golf club includes not only physical vibrations but also sensory pleasures (feelings) such as the feel of the shot, the sense of control, and the sense of accomplishment. Furthermore, even with golf clubs that lack a hosel, there is the challenge of not being able to achieve a good feel without some kind of modification.

[0005] One of the objectives of this project is to provide a golf club, a golf practice system, a golf club insert, and a portable mobile terminal that have been devised in light of the above-mentioned problems and that can improve the feel of the ball. In addition, other objectives of this project can be positioned as achieving effects that cannot be obtained with conventional technology, derived from each configuration shown in the "Modes for Carrying Out the Invention" described later.

[Modes for carrying out the invention]

[0015] [Description of the first embodiment] [Basic structure] Figures 1(A) and 1(B) are perspective views illustrating a golf club 1 (putter) as a first embodiment. This golf club 1 comprises a head 3, a shaft 5, a hosel 4, and a grip 6. The side of the head 3 is provided with a striking surface 2 (face) for striking the golf ball. The shaft 5 is formed in an axial shape (a long, slender rod shape), and one end of it (the lower end in Figure 1) is connected to the head 3. The cross-sectional shape of the shaft 5 may be circular, elliptical, or polygonal. The grip 6, which is the part held by the user, is provided at the other end of the shaft 5 (the upper end in Figure 1). Similar to the shaft 5, the cross-sectional shape of the grip 6 may be circular, elliptical, or polygonal. Although Figure 1 shows a pin-type head 3 as an example, the shape of the head 3 is not particularly limited and can be any well-known shape, such as a mallet type or neo-mallet type.

[0016] In the golf club 1 shown in Figures 1(A) and 1(B), a diaphragm member 200 is attached to the head 3, hosel 4, and shaft 5 as a striking vibration / sound enhancement mechanism that amplifies the impact vibration or sound generated when a golf ball strikes the striking surface 2 and transmits it to the user. Note that Figures 1(A) and 1(B) show the golf club 1 and the diaphragm member 200 disassembled.

[0017] The golf club 1 in Figure 1(A) has a crank-shaped hosel 4 that has two bends that bend toward the front of the head 3 (towards the side where the striking surface 2 is located), and the upper part of the hosel is located in front of the lower end of the head 3, whereas the golf club 1 in Figure 1(B) has a straight shaft 5. In the golf club 1 in Figure 1(A), the shaft 5 and the head 3 are connected by a hosel 4 that has bends that bend toward the front of the head 3 (towards the side where the striking surface 2 is located).

[0018] The hosel 4 is a coupling member that connects the lower end (one end) of the shaft 5 to the head 3. By connecting the lower end of the shaft 5 and the head 3 via the hosel 4, it is easier to connect the lower end of the shaft 5 and the head 3 compared to a structure without a hosel. The shape of the hosel 4 is not particularly limited and can be any well-known shape. Regarding the connection structure between the head 3 and the shaft 5 of the golf club 1, any well-known structure may be applied, such as those shown in Figures 1(A) and (B), where the shaft 5 is connected to the head 3 via a crank-shaped hosel 4, where a straight shaft 5 is connected to the head 3, or where a crank-shaped shaft 5 is connected to the head 3.

[0019] <Flat plate-shaped vibrating plate component> The diaphragm member 200 is a plate member designed to amplify the impact vibrations generated when a golf ball is struck. Its thickness, rigidity, shape, and material are set to emphasize these impact vibrations. This diaphragm member 200 is an example of a surface vibrating member formed in a planar shape that vibrates upon impact with a golf ball. In other words, the golf club 1 can be said to have the diaphragm member 200 as a surface vibrating member. In the golf club 1 shown in Figures 1(A) and (B), the diaphragm member 200 is formed as a thin, flat plate extended in a planar direction parallel to the striking surface 2.

[0020] The diaphragm member 200 may be attached integrally with the head 3 in a non-removable (non-detachable) manner, or it may be attached to the head 3 in a detachable (retrofittable, separate) manner. Any conventionally known method such as bonding, crimping, welding, or fitting may be used to attach the diaphragm member 200 to the head 3, either in a non-detachable or detachable manner.

[0021] Figure 2(A) is a side view of the golf club 1 in Figure 1(B) as seen from arrow A, with the left side of the figure being the side (front) where the striking surface 2 of the head 3 is formed. As shown in Figure 2(A), the head-corresponding portion 200A of the diaphragm member 200 is attached to the front side of the striking surface 2 of the head 3. The head-corresponding portion 200A of the diaphragm member 200 is the part of the diaphragm member 200 that corresponds to the head 3. The head-corresponding portion 200A of the diaphragm member 200 is formed in a shape that covers part or all of the head 3. In other words, the head-corresponding portion 200A of the diaphragm member 200 functions as the striking surface 2.

[0022] According to this golf club 1, the impact vibration generated when the golf ball is struck is transmitted to the head-compatible portion 200A (impact vibration / impact sound enhancement mechanism) of the diaphragm member 200 and amplified by the head-compatible portion 200A (impact vibration / impact sound enhancement mechanism) of the diaphragm member 200. Therefore, the vibrations transmitted from the head-compatible portion 200A of the diaphragm member 200 to the hosel-compatible portion of the diaphragm member 200 and the shaft-compatible portion of the diaphragm member 200 through the grip 6 to the user's palm, as well as the impact sound (acoustic) heard by the user, can be amplified. Since the diaphragm member 200 is provided across the head 3, hosel 4 and shaft 5, or the head 3 and shaft 5, vibrations generated by the impact of the golf ball are more easily transmitted to the grip 6. Therefore, the feel and sound of the impact can be improved compared to existing golf clubs that do not have the diaphragm member 200 attached.

[0023] Figure 2(B) shows a configuration in which, in addition to the diaphragm member 200 with the head-compatible portion 200A attached to the front side of the head 3, there is a sub-diaphragm member 201. The sub-diaphragm member 201 is attached to the back side of the head 3, opposite to the front. The sub-diaphragm member 201 is a plate member that has the same function as the diaphragm member 200 in emphasizing the impact vibrations generated when a golf ball is struck, and is provided as a separate plate member from the diaphragm member 200.

[0024] In this case, the impact vibration generated when the golf ball is struck is transmitted to the diaphragm member 200 (impact vibration / impact sound enhancement mechanism) and amplified by the diaphragm member 200 (impact vibration / impact sound enhancement mechanism), and is also transmitted to and amplified by the sub-diaphragm member 201. This enhances the vibration transmitted to the user's palm and the impact sound (acoustic) heard by the user, thereby improving the feel and sound of the impact.

[0025] <Hollow section of the head and diaphragm component> In Figures 3(A) and 3(B), the golf club 1 is a modified example of Figures 2(A) and 2(B), and has a hollow head portion 202 (shown by a dashed line in the figure) formed in a hollow shape. In Figure 3(A), the golf club 1 has an opening 202A on the front side of the head 3 that communicates with the hollow part of the head 202 and the outside, and the head-corresponding portion 200A of the vibrating plate member 200 is attached so as to cover the opening 202A.

[0026] In Figure 3(B), the golf club 1 has openings 202A and 202A' on both the front and back sides of the head 3, which communicate between the hollow part of the head 202 and the outside. The head-corresponding portion 200A of the diaphragm member 200 and the sub-diaphragm member 201 are attached to cover the openings 202A and 202A'. The head 3 in Figure 3(B) can also be described as having a drum-shaped structure in which both sides of the hollow part of the head 202 (openings 202A and 202A') are covered by the head-corresponding portion 200A of the diaphragm member 200 and the sub-diaphragm member 201.

[0027] In the golf club 1 shown in Figures 3(A) and 3(B), the hollow head portion 202 forms a resonance mechanism that amplifies the impact sound generated when the golf ball is struck and transmits it to the outside through the opening 202A (and 202A'). In other words, the golf club 1 shown in Figures 3(A) and 3(B) has a hollow head portion 202 that forms a resonance mechanism as an impact vibration / impact sound amplification mechanism. Therefore, by amplifying the impact sound generated when the golf ball is struck by the hollow head portion 202, the impact sound (acoustics) heard by the user can be improved.

[0028] Furthermore, since the diaphragm member 200 (and the sub-diaphragm member 201) is attached to the opening 202A (and 202A'), the feel and sound of impact can be further improved. In addition, in Figures 3(A) and (B), the hollow head portion 202 forming the resonance mechanism may have a structure in which it does not have an opening 202A (and 202A').

[0029] Figure 4(A) is a side view of the head 3, rectangular hosel 4, and shaft 5 of the golf club 1, with the left side of the figure being the front of the head 3. In Figure 4(A), the hosel-compatible portion 200B of the diaphragm member 200 is attached to the front side of the hosel 4. The hosel-compatible portion 200B of the diaphragm member 200 is formed to cover part or all of the hosel 4. The hosel-compatible portion 200B of the diaphragm member 200 may be formed separately from the hosel 4 or may be formed integrally with the hosel 4.

[0030] In this case, the impact vibration generated when the golf ball is struck is transmitted from the head-compatible portion 200A of the vibrating plate member 200 to the hosel-compatible portion 200B of the vibrating plate member 200 and amplified by the vibrating plate member 200 (impact vibration / impact sound enhancement mechanism). Therefore, the vibrations transmitted from the hosel-compatible portion 200B and shaft-compatible portion 200C of the vibrating plate member 200 to the user's palm through the grip 6, as well as the impact sound (acoustic) heard by the user, can be enhanced (reinforced). Thus, the feel and sound of the impact can be improved compared to existing golf clubs that do not have the vibrating plate member 200 attached.

[0031] Figure 4(B) is a modified example of Figure 5(A). The golf club 1 in Figure 5(B) has a diaphragm member 200 attached to the front side of the hosel 4, as well as a secondary diaphragm member 201 attached to the rear side of the hosel 4. In this case as well, the impact vibrations generated when the golf ball is struck are transmitted from the head 3 to the diaphragm member 200 attached to the hosel 4 and amplified by the diaphragm member 200. This enhances the vibrations transmitted to the user's palm and the impact sound (acoustic) heard by the user, thereby improving the feel and sound of the impact.

[0032] In addition, in a golf club 1 having a hosel 4 as shown in Figures 4(A) and (B), in addition to the vibrating plate member 200 (and sub-vibrating plate member 201) attached to the hosel 4, a sub-vibrating plate member 201 may also be attached to the head 3 as shown in Figures 2(A) and (B). The vibrating plate member 200 shown in Figures 2 to 4 above may be formed from a single plate-like member, with head-compatible portion, hosel-compatible portion, and shaft-compatible portion corresponding to the head 3, hosel 4, and shaft 5, respectively, or each portion may be formed entirely or partially as separate parts.

[0033] The golf club 1 shown in Figures 5(A) to (C) is a golf club 1 having a rectangular flat hosel 4, and a vibrating plate member 200 (impact vibration / impact sound enhancement mechanism) is attached to the head 3, hosel 4, and shaft 5. The vibrating plate member 200 shown in Figures 5(A) to (C) is formed from a single plate-like member that extends from the head 3, hosel 4, and shaft 5, with a head-compatible portion 200A, a hosel-compatible portion 200B, and a shaft-compatible portion 200C. Note that each part may be formed as a separate component, either entirely or partially.

[0034] The diaphragm member 200 in Figure 5(A) is formed from a single plate-like member that extends from the head 3 through the hosel 4 to the front side of the shaft 5. The golf club 1 in Figure 5(B) is the same as the golf club 1 in Figure 5(A), but with a sub-diaphragm member 201 attached to the back side of the hosel 4 in addition to the diaphragm member 200.

[0035] <Bending shape of the diaphragm component> Furthermore, in the golf club 1 shown in Figure 5(C), the vibrating plate member 200, which is attached from the head 3 through the hosel 4 to the shaft 5, has a crank-shaped (S-shaped) bend when viewed from the side. Specifically, the vibrating plate member 200 in Figure 5(C) has a head-compatible portion 200A attached to the back side of the head 3, a hosel-compatible portion 200B attached to the front side of the hosel 4, and a shaft-compatible portion 200C attached to the front side of the shaft 5, with the head-compatible portion 200A and the hosel-compatible portion 200B being connected via a bent portion.

[0036] In the golf club 1 shown in Figures 5(A) to (C), the impact vibration generated when the golf ball is struck is transmitted from the head 3 through the hosel 4 to the shaft 5, to the vibrating plate member 200 (impact vibration / impact sound enhancement mechanism), which amplifies the vibration transmitted to the user's palm and the impact sound (acoustic) heard by the user, thereby improving the feel and sound of the impact. In addition, in Figure 5(C), the diaphragm member 200 may have a rounded shape at the corners of the bent portion.

[0037] <Hosel hollow section and diaphragm component> Figure 6(A) is a modified example of Figure 5(B), in which the head 3 has a head hollow portion 202 (shown by a dashed line in the figure) and an opening 202A, and the hosel 4 has a hollow hosel hollow portion 203 (shown by a dashed line in the figure), an opening 203A on the front side and an opening 203A' on the rear side. In Figure 6(A), the diaphragm member 200 is mounted so as to cover the opening 202A of the head hollow portion 202 and the front opening 203A of the hosel hollow portion 203. The sub-diaphragm member 201 is mounted so as to cover the rear opening 203A of the hosel hollow portion 203.

[0038] Figure 6(B) is a modified example of Figure 6(A). In Figure 6(A), the head hollow section 202 and the hosel hollow section 203 are formed separately and are not in communication. In contrast, in Figure 6(B), the head hollow section 202 and the hosel hollow section 203 are in communication. In the golf club 1 shown in Figures 6(A) and 6(B), the hollow head section 202 and the hollow hosel section 203, which form a resonance mechanism, amplify the impact sound generated when the golf ball is struck, thereby improving the sound (acoustics) heard by the user. Furthermore, the diaphragm members 200 (and sub-diaphragm members 201) attached to the openings 202A, 203A (and 203A') can further improve the feel and sound of the impact.

[0039] Although the golf club 1 shown in Figures 6(A) and 6(B) is an example that has both a diaphragm member 200 and a sub-diaphragm member 201 as shown in Figure 5(B), even in a golf club 1 that has a diaphragm member 200 but no sub-diaphragm member 201, as shown in Figure 5(A), the feel and sound of impact can be improved by providing a head hollow section 202 and a hosel hollow section 203 that form a resonance mechanism, as well as openings 202A, 203A (and 203A'), as shown in Figures 6(A) and 6(B).

[0040] <Variations in the shape of the hosel> The golf club 1 in Figures 7(A) to 7(F) is a modified example with respect to the shape of the hosel 4. The golf club 1 in Figure 7(A) has a hosel 4 that is trapezoidal (or roughly triangular) when viewed from the front, and a vibrating plate member (not shown) is attached to the head 3, hosel 4, and shaft 5.

[0041] The golf club 1 in Figure 7(B) has a semicircular hosel 4 that forms a semicircular shape (or arc shape) when viewed from the front, and a vibrating plate member (not shown) is attached to the head 3, hosel 4, and shaft 5. The golf club 1 in Figure 7(C) differs from that in Figure 8(A) in that it has a trapezoidal hosel 4, and the front of the hosel 4 is located on the rear side (not flush) of the head 3 (hitting surface 2). In the golf club 1 in Figure 7(C), a vibrating plate member (not shown) can be attached across the head 3, hosel 4, and shaft 5.

[0042] Regardless of the shape of the hosel 4 of each golf club 1 shown in Figures 7(A) to (C), the diaphragm member 200 (and sub-diaphragm member 201) can be attached in the manner described above. Figures 7(A) to (C) are illustrative examples, and the shape, size, and thickness of the hosel 4 may be any. In other words, regardless of the shape, size, or thickness of the hosel 4, the feel and sound of striking can be improved by attaching the diaphragm member 200 (and the sub-diaphragm member 201).

[0043] Furthermore, a crank-shaped shaft 5, which is bent forward of the head 3, is connected to each golf club 1 shown in Figures 7(D) to (E). In this case, the vibrating plate member 200, which spans the head 3, hosel 4, and shaft 5, is formed such that the shaft-corresponding portion 200C of the vibrating plate member 200 follows the crank shape of the shaft 5, and is formed in a crank shape that is bent forward of the head 3 relative to the golf club 1. Note that the structure connecting the hosel 4 and the shaft 5 may be any well-known structure.

[0044] <Head hosel frame structure> Figure 8 is a front view of the golf club 1, showing the head 3 and hosel 4 in cross-section.

[0045] The golf club 1 in Figure 8 has frame structures 3F and 4F surrounding the periphery of the head-corresponding portion 200A and hosel-corresponding portion 200B of the vibrating plate member 200, with the head 3 and hosel 4 being the same. The frame structures 3F and 4F in Figure 8 are integrally formed. In this case, the vibrating plate member 200 enclosed by the frame structures 3F and 4F can improve the feel and sound of the impact by emphasizing the impact vibration and sound generated when the golf ball is struck. Furthermore, since the head 3 and hosel 4 are formed from a frame, it is easy to reduce the weight.

[0046] The golf club 1 illustrated in Figures 9(A) and 9(B) has a hosel 4 that is trapezoidal (or roughly triangular) when viewed from the front. In the golf club 1 of Figure 9(A), the hosel 4 has a frame structure 4F, while in the golf club 1 of Figure 9(B), both the head 3 and the hosel 4 have frame structures 3F and 4F. In the golf club 1 of Figure 9(A), the diaphragm member 200 is provided across the head 3, hosel 4, and shaft 5, and the hosel 4 with the frame structure 4F surrounds the periphery of the hosel-corresponding portion 200B of the diaphragm member 200. In the golf club 1 of Figure 9(B), the diaphragm member 200 is provided across the head 3, through the hosel 4, and onto the shaft 5, and the head 3 and hosel 4 with frame structures 3F and 4F surround the periphery of the head-corresponding portion 200A and the hosel-corresponding portion 200B of the diaphragm member 200.

[0047] The golf club 1 illustrated in Figures 10(A) and (B) is a modified example of the golf club 1 illustrated in Figures 9(A) and (B) above, with a different shape for the hosel 4, having a semicircular hosel 4. The golf club 1 in Figure 10(A) has a frame structure 4F for the hosel 4, while the golf club 1 in Figure 10(B) has frame structures 3F and 4F for both the head 3 and the hosel 4.

[0048] The golf club 1 in Figures 9(A) and 9(B), and Figures 10(A) and 10(B) all produce the same effect as the golf club 1 in Figure 8. Figure 11 shows a golf club 1 in which the head 3 and hosel 4, which have frame structures 3F and 4F, are integrally formed with the shaft 5 in a manner that prevents replacement. In this case as well, it produces the same effect as the golf club 1 in Figure 8.

[0049] Figures 12(A) to (F) show examples of a golf club 1 that, in addition to the diaphragm member 200 provided across the head 3, hosel 4, and shaft 5, is also provided with a frustoconical (cone-shaped) diaphragm member 200S. Each frustoconical diaphragm member 200S in Figures 12(A) to (F) is mounted with the larger diameter side of the frustoconical shape facing the back of the head 3.

[0050] The golf club 1 in Figure 12(A) does not have a hosel 4, and a frustoconical vibrating plate member 200S is attached to the back side of the head 3. The golf club 1 in Figure 12(B) has a hosel 4, and a frustoconical vibrating plate member 200S is attached to the back side of the hosel 4. In this case, the impact sound can be particularly emphasized in the direction facing the larger diameter side of the frustoconical diaphragm member 200S (towards the back of the head 3).

[0051] The golf club 1 in Figure 12(C) differs from the golf club 1 in Figure 12(A) in that it has an enclosure 200E surrounding the frustoconical diaphragm member 200S. Figure 12(D) shows two frustoconical diaphragm members 200S and 200S' arranged coaxially. According to the structures in Figures 12(C) and (D), the impact sound can be further emphasized.

[0052] Figure 12(E) shows an example of a golf club 1 in which, in addition to the diaphragm member 200 provided across the head 3, hosel 4, and shaft 5, a dome-shaped diaphragm member 200S is provided. In the golf club 1 of Figure 12(E), the dome-shaped diaphragm member 200S is attached to the back side of the head 3. The dome-shaped diaphragm member 200S is attached in a position that is convex toward the back side of the head 3. In this case, the impact sound can be particularly emphasized in the direction in which the convex side of the dome-shaped diaphragm member 200S is facing (towards the back side of the head 3).

[0053] The golf club 1 in Figure 12(F) has a diaphragm member 200 that extends across the head 3, hosel 4, and shaft 5, as well as a diaphragm member 200S that combines a frustoconical diaphragm member and a dome-shaped diaphragm member. That is, the diaphragm member 200S has a dome-shaped diaphragm member (shown by a dashed line in the figure) and a frustoconical diaphragm member that extends in a frustoconical shape from around the dome-shaped diaphragm member. In Figure 12(F), the diaphragm member 200S is attached to the back side of the head 3 with the larger diameter side of the frustoconical diaphragm member and the convex part of the dome-shaped diaphragm member facing the back side of the head 3. In this case, the combination of the two types of diaphragm members can further emphasize the impact sound.

[0054] <Diaphragm component for curved speaker type> Figures 13(A) to (H) are explanatory diagrams of a golf club 1 having a diaphragm member 200 provided across the head 3, hosel 4, and shaft 5, as well as a curved diaphragm member 200Q formed in the shape of a curved plate. Each of the curved diaphragm members 200Q and 200Q' is curved in an arc shape, and the vibration of the arc-shaped curved surface emphasizes the impact vibration and impact sound. It is well known that by utilizing the vibration of such a curved surface, it is possible to improve the acoustics based on vibration (improvement of volume and audibility).

[0055] The golf clubs 1 in Figures 13(A)-(C) and (G) have an L-shaped head 3 when viewed from the side. The golf clubs 1 in Figures 13(D), (E), and (H) have a U-shaped head 3 when viewed from the side, and Figure 17(F) has an L-shaped head 3 and hosel 4 when viewed from the side. In the golf club 1 of Figure 17(F), the head 3 and hosel 4 are assembled in a U-shape when viewed from the side.

[0056] The curved diaphragm member 200Q shown in Figures 13(A) to (C) is mounted in a position that extends toward the back side of the head 3, and is formed in a curved plate shape that is curved upward or downward in a longitudinal cross section perpendicular to the striking surface 2 (the surface when the head 3 is viewed from the side). The curved diaphragm member 200Q in Figures 13(A) and (C) is curved upward in a longitudinal cross section perpendicular to the striking surface 2. The curved diaphragm member 200Q in Figure 13(B) is curved downward in a longitudinal cross section perpendicular to the striking surface 2.

[0057] The golf club 1 in Figures 13(D) and (E) is an example configuration in which two curved vibrating plate members 200Q and 200Q' are provided on the back side of the head 3, and the golf club 1 in Figure 13(F) is an example configuration in which two curved vibrating plate members 200Q and 200Q' are provided on both the back side and the back side of the head 3. Each vibrating plate member 200Q and 200Q' is mounted in a position extending toward the back side of the head 3 and is formed in a curved plate shape that is curved upward or downward in a longitudinal cross section perpendicular to the striking surface 2. Furthermore, the golf club 1 in Figure 13(H) is configured in the same way as the golf club 1 in Figure 13(F), except that, in a side view, the curved diaphragm members 200Q and 200Q' are attached to a U-shaped head 3. The difference from the golf club 1 in Figure 13(D) is that the curved diaphragm members 200Q and 200Q' are spaced apart from each other. The orientation, dimensions, curvature, and other combinations of each diaphragm member 200Q, 200Q' can be freely set, not limited to the examples shown in Figures 13(D) to (F) and (H).

[0058] The golf club 1 shown in Figure 13(G) has a combination of the frustoconical diaphragm member 200S illustrated in Figure 12(A) and the curved diaphragm member 200Q described above. By combining two different types of diaphragm members, further improvement in the impact sound can be achieved. Figures 14(A) to (C) show modified examples of the curved diaphragm member 200Q with respect to the bending direction. Figures 14(A) to (C) are plan views of the head 3 seen from above, with the left side of the paper being the front side.

[0059] The golf club 1 shown in Figures 14(A) to (C) has a diaphragm member 200 provided across the head 3, hosel 4, and shaft 5, as well as a curved diaphragm member 200Q that forms a bent plate shape in one (or the other) direction in the width direction when viewed from above on the horizontal plane of the head 3. The head 3 in Figures 14(A) and (B) is provided with two curved diaphragm members 200Q and 200Q'. The golf club 1 shown in Figure 14(C) has a combination of the frustoconical diaphragm member 200S exemplified in Figure 12(A) and the above-mentioned curved diaphragm member 200Q. Note that in Figure 14(B), the curved diaphragm members 200Q and 200Q' may be formed as a single unit.

[0060] <Modified example of a bent plate-shaped diaphragm member> Figures 15(A) to (E) are plan views showing modified examples of the curved diaphragm member 200Q, with the left side of the paper being the front side. Figures 15(A) to (C) show a modified example of the curved diaphragm member 200Q, in which an arc-shaped curved diaphragm member 200Q that convex toward the rear side of the head 3 in the horizontal plane when viewed from above is attached to the rear side of the head 3. Figure 15(A) shows the curved diaphragm member 200Q attached to the rear side of the head 3, with a rib 200R attached between the curved diaphragm member 200Q and the rear side of the head 3 in a direction that intersects the arc. The rib 200R reinforces the curved diaphragm member 200Q and improves vibration transmission.

[0061] Figure 15(B) shows an example in which a curved diaphragm member 200 is installed in a recess 3X formed in the upper surface of the head 3. Figure 15(C) shows the recess 3X in which the curved diaphragm member 200Q is installed in Figure 19(B) covered with a lid 3Y.

[0062] Figure 15(D) shows a head 3 with a curved diaphragm member 200Q attached to its back side, forming a concave arc towards the back side of the head 3 in a horizontal view of the head 3 from above. In Figure 15(D), a rib 200R is attached to the curved surface of the curved diaphragm member 200Q, extending along the arc. One or more ribs 200R may be attached. The multiple ribs 200R may be arranged side by side, for example, in the vertical direction. That is, there may be one or more ribs 200R. Figure 15(E) shows a mallet-type head 3 with a sole portion 3W extending to the flat side, and a head-compatible portion 200A of a curved diaphragm member 200Q attached to the upper surface of the sole portion 3W.

[0063] <Horn-type resonant structure; Dome-type resonant structure> Figures 16(A) and (B) illustrate a golf club 1 according to the second embodiment, showing the head 3 and hosel 4 in a cross-sectional view from the side. The golf club 1 in Figure 16(A) has a diaphragm member 200 that extends across the head 3, hosel 4, and shaft 5. In addition, the head 3 and hosel 4 have a horn-shaped conduit 206 formed in the hollow section 202, and an opening 206A that communicates with the conduit 206 is provided. The conduit 206 and the opening 206A are configured as a resonance mechanism (horn-type resonance mechanism, phonograph-type resonance mechanism) that amplifies the impact sound generated when a golf ball is struck within the conduit 206 and transmits it to the outside through the opening 206A. The conduit 206 has an R-shape, with its diameter widening towards the opening 206A, which provides excellent acoustic characteristics and thus further improves the impact sound.

[0064] In the golf club 1 shown in Figure 16(B), in addition to the vibrating plate member 200 provided across the head 3, hosel 4, and shaft 5, the head 3 and hosel 4 have a dome-shaped (spherical) conduit 206 formed in the hollow section 202, and an opening 206A is provided that communicates with the conduit 206. The conduit 206 and the opening 206A are configured as a resonance mechanism (dome-shaped resonance mechanism) that amplifies the impact sound generated when a golf ball is struck within the conduit 206 and transmits it to the outside through the opening 206A. In this case, the dome-shaped conduit 206 can be used to resonate the impact sound, thereby improving the impact noise.

[0065] The golf club 1 shown in Figure 17(A) has a cylindrical diaphragm member 200T in addition to the diaphragm member 200 provided across the head 3, hosel 4, and shaft 5. Alternatively, as shown in Figure 17(B), the golf club 1 may have a plate-shaped diaphragm member 200U extending horizontally from the back of the head 3. The plate-shaped diaphragm member 200U can be attached to the head 3 by bending its end into an L-shape and fixing it to the back of the head 3 at the L-shaped bend. Other methods for attaching the plate-shaped diaphragm member 200U to the head 3 include, for example, inserting the end of the plate-shaped diaphragm member 200U into the back of the head 3, welding the end of the plate-shaped diaphragm member 200U to the back of the head 3, or integrally molding the plate-shaped diaphragm member 200U with the head.

[0066] Figure 17(C) is a top view of Figure 17(B). As shown in Figure 17(C), multiple plate-shaped diaphragm members 200U of different lengths are arranged side by side in the width direction of the head 3 on the back side of the head 3. That is, the number of plate-shaped diaphragm members 200U may be one or more. In the case of Figures 17(B) and (C), the plate-shaped diaphragm members 200U are supported in a cantilevered manner on the back side of the head 3 and vibrate, and sound can be generated by the vibration of the plate-shaped diaphragm members 200U, similar to the musical instrument marimba.

[0067] Furthermore, as shown in Figures 18(A) and (B), a spoiler 204 can be attached between the curved diaphragm member 200Q and the head 3. The spoiler 204 is detachable from the golf club 1 and can be retrofitted. In other words, the impact vibration and sound can be improved by retrofitting the spoiler 204 to an existing golf club.

[0068] Figures 19(A) to (D) show examples of the shape of an additional vibrating plate member 200N that can be attached to the golf club 1 in addition to the vibrating plate member 200 provided across the head 3, hosel 4, and shaft 5, and are side views of the additional vibrating plate member 200N. The center of gravity can be adjusted by attaching weights to these additional vibrating plate members 200N, or blades can be detachably attached to the additional vibrating plate member 200N. The shapes of the additional vibrating plate members 200N in Figures 19(A) to (D) are examples of shapes that can improve impact vibration and impact sound.

[0069] Shapes that can improve impact vibration and impact sound include a C-shape (steel drum type) as shown in Figure 19(A), an L-shape as shown in Figure 19(B), a shape combining an L-shape with a horizontally extending plate as shown in Figure 19(C), and a C-shape as shown in Figure 19(D) in which the sole portion (bottom surface) extends horizontally to the rear of the head 3. In addition, for example, as shown in Figure 19(B), a detachable weight or blade member 200X may be attached to the end of the additional vibrating plate member 200N. The center of gravity of the golf club 1 can be adjusted by member 200X. With member 200X, in addition to the original center of gravity of the golf club 1, a center of gravity can also be set on the back side of the head 3 (double balance). This makes it easier to strike through during the follow-through.

[0070] <Integration of diaphragm component and shaft / hosel> Figures 20(A) to (D) show the diaphragm member 200 in which the hosel-compatible portion 200B and the shaft-compatible portion 200C are integrally formed and cannot be replaced with the shaft 5 and hosel 4. Because the diaphragm member 200, hosel 4 and shaft 5 are integrated, the impact vibrations generated when the golf ball is struck can be directly transmitted to the shaft 5.

[0071] In Figure 20(A), a diaphragm member 200, which is integrated with the shaft 5 and hosel 4, is detachably attached to a frame-shaped head 3. The head-compatible portion 200A of the diaphragm member 200 is positioned with gaps on both the left and right sides relative to the frame-shaped head 3, and these gaps are closed by a plate member 200Y. Since the head-compatible portion 200A of the diaphragm member 200 is provided at a distance from the head 3, the impact vibrations generated when the golf ball is struck can be efficiently guided to the shaft 5 without being dispersed to the head 3. Alternatively, as shown in Figure 27(B) below, the head-compatible portion 200A of the diaphragm member 200 may be provided without gaps on both the left and right sides relative to the frame-shaped head 3. The plate member 200Y may also be a diaphragm member. That is, a diaphragm member made of a different material than the diaphragm member 200 integrated with the hosel 4 and shaft 5 may be installed in place of the plate member 200Y. In this case, different types of diaphragm members can be combined.

[0072] Figure 20(B) shows a diaphragm member 200, which is integrated with a hosel 4 and a shaft 5, being detachably attached to a frame-shaped head 3, with the left and right sides of the upper surface of the head-compatible portion 200A of the diaphragm member 200 being closed off by cover members 200Z. Alternatively, a front cover member 200K that covers the entire surface of the head 3 may be detachably attached to the front side of the head 3 by overlapping it with the head-compatible portion 200A of the diaphragm member 200 from the front.

[0073] Figure 20(C) shows a circular head-compatible portion 200A of the diaphragm member 200, which is integrated with the hosel 4 and shaft 5. In the circular shape, the mounting angle relative to the head 3 can be adjusted. In this case, a locking mechanism is provided to fix the mounting angle after it has been adjusted. In Figure 20(D), the golf club 1 has a head-corresponding portion 200A of the vibrating plate member 200, which is integrated with the hosel 4 and shaft 5, and is formed in a rectangular shape.

[0074] In the golf club 1 shown in Figures 20(A) to (D), the hosel-compatible portion 200B and shaft-compatible portion 200C of the vibrating plate member 200 are integrated with the shaft 5 and / or hosel 4, and the head-compatible portion 200A of the vibrating plate member 200 is detachably attached to a separate head 3. Therefore, the vibrating plate member 200 can be freely combined with the head 3. The vibrating plate member 200 can be attached to and detached from the head 3 as easily as changing a cartridge (cassette tape). In other words, this golf club 1 can be configured as an assembly-type golf club in which the user can freely select and assemble various parts such as the vibrating plate member 200, face (hitting surface), weight, balance, insert, hosel, and sub-vibrating plate member 201 with respect to the head 3.

[0075] Furthermore, the golf club 1 shown in Figures 20(A) to (D) is not limited to a straight shaft; it may also have a structure in which the hosel-compatible portion 200B and shaft-compatible portion 200C of the vibrating plate member 200 are integrated with the crank-shaped hosel 4 / shaft 5. The insert may be placed on the front surface of the head-compatible portion 200A of the diaphragm member 200, or the insert may be built into the head-compatible portion 200A of the diaphragm member 200. The head-compatible portion 200A of the diaphragm member 200 may be formed integrally with the insert, or the insert may be detachably attached to it. The shape of the diaphragm member 200 is not limited to the illustrated example and is flexible.

[0076] <Vibration transmission ribs; fan ribs> Figure 21 shows a golf club 1 according to the third embodiment, which is equipped with a vibration transmission rib 210 as a striking vibration / sound amplification mechanism. As shown in Figure 21, the vibration transmission rib 210 extends in a rib shape from the head 3 to the shaft 5, and transmits the impact vibrations generated when the golf ball is struck from the head 3 to the shaft 5. The vibration transmission rib 210 is formed as a ridged protrusion on the front surface of the shaft 5 from the head 3, and is designed to amplify the impact vibrations.

[0077] The golf club 1 in Figure 21 is a golf club 1 having a hosel 4 and a vibration transmission rib 210 provided on it. More specifically, the vibration transmission rib 210 has a plurality of branch portions 210A attached to the head 3 and hosel 4, and a main body 210B that extends along the axial direction of the shaft 5 and is connected to the branch portions 210A at the lower end of the shaft (for example, it has a shape like the ribs of a fan). By providing vibration transmission ribs 210, the impact vibrations transmitted to the user's palm can be increased, improving the feel of the ball.

[0078] Other variations are shown in Figures 22(A)-(F) and 23(A)-(B). The golf club 1 shown in Figure 22(A) has a structure in which, in addition to the vibrating plate member 200 provided across the head 3, hosel 4, and shaft 5, the bowl-shaped (bell-shaped) head 3 has an opening 202A on the upper side of the hollow part 202 of the head closed by a lid-type vibrating plate member 200D. In this case, the impact sound generated when the golf ball is struck by the striking surface 2 of the head 3 resonates within the hollow part 202 of the head and is emitted to the outside through the opening 202A, while the impact vibration is amplified by the vibrating plate members 200 and 200D. It is not necessary to provide a lid-type diaphragm member 200D that closes the opening 202A. In that case, the effect of emphasizing the impact sound within the hollow part 202 of the head can still be obtained.

[0079] Figure 22(B) shows a configuration in which, in addition to a vibrating plate member (not shown) provided across the head 3, hosel 4, and shaft 5, a fin 5X is attached between the hosel 4 and the head 3. The fin 5X is provided as a thin plate-shaped or membrane-shaped vibrating plate member, and the impact vibration can also be emphasized by the fin 5X. The fin 5X may be detachably attached to the golf club 1 (head 3). In this case, the impact vibration can be emphasized by attaching the fin 5X to an existing golf club.

[0080] The golf club 1 in Figure 22(C) includes, in addition to the diaphragm member 200 provided across the head 3, hosel 4, and shaft 5, a sound amplification mechanism for impact vibration / impact sound, which includes a sound collector 220 attached to the back of the head 3 to collect impact sounds, an impact sound propagation tube 221 that propagates the impact sounds collected by the sound collector 220, and an earphone unit 222 that transmits the impact sounds propagated through the impact sound propagation tube 221 to the user. In this case, the user can clearly hear the impact sound collected by the sound collector 220 through the earphone unit 222. Alternatively, a wireless structure may be used in which the sound collector 220 and the earphone unit 222 are wirelessly connected, and the impact sound collected by the sound collector 220 is transmitted to the earphone unit 222 via wireless communication, without providing the impact sound transmission tube 221.

[0081] The sound collector 220, the impact sound transmission tube 221, and the earphone unit 222 may be detachably attached to the golf club 1 (head 3). In this case, the sound collector 220, the impact sound transmission tube 221, and the earphone unit 222 can be freely attached to an existing golf club.

[0082] The golf club 1 in Figure 22(D) has a vibrating plate member 200 that extends across the head 3, hosel 4, and shaft 5, as well as a striking vibration / sound amplification mechanism which includes a pickup 230 that detects striking vibrations and converts them into electrical signals, an amplifier unit 231 that amplifies the striking sound based on the electrical signals detected by the pickup 230, and a speaker 232 that outputs the amplified striking sound. The amplifier unit 231 and the speaker 232 constitute the "speaker unit". The pickup 230 (dashed line in the figure), the amplifier unit 231 (dashed line in the figure), and the speaker 232 are mounted on the back side of the head 3. In this case, the impact vibration is converted into an electrical signal, and the impact sound can be electrically amplified and output from the speaker unit, allowing the impact sound to be output more clearly.

[0083] Figure 22(E) is a modified example of Figure 22(D), in which, in addition to the diaphragm member 200 provided across the head 3, hosel 4, and shaft 5, a pickup 230 (dashed line in the figure), an amplifier unit 231 (dashed line in the figure), and a speaker 232 (dashed line in the figure) are provided within the hollow head portion 202 of the head 3. The pickup 230, amplifier unit 231, and speaker 232 may be detachably attached to the golf club 1 (head 3). In this case, the pickup 230, amplifier unit 231, and speaker 232 can be freely attached to an existing golf club.

[0084] The head 3 shown in Figure 22(F) has a thin plate on the front side with the striking surface 2, and the striking vibration is emphasized by making the plate thickness on the striking surface 2 side thin. As shown in Figure 22(F), batteries 3E are detachably provided on both sides of the head 3, and by appropriately wiring power lines from batteries 3E, it is possible to attach various electrical functions to the head 3. Examples of electrical functions that can be attached to the head 3 include LED lights, electrical decorations, lasers, sensors, testers, and communication functions.

[0085] Figures 23(A) and (B) are explanatory diagrams of a golf club 1 in which, in addition to a vibrating plate member (not shown) provided across the head 3, hosel 4, and shaft 5, a vibration-enhancing member is attached to the shaft 5, and are radial cross-sectional views of the shaft 5. The vibration-enhancing member is a member that amplifies the impact vibrations generated when a golf ball strikes the impact surface 2 and transmits them to the user, and is provided on the circumferential surface of the shaft 5 around its axis, extending in the axial direction of the shaft 5.

[0086] In Figure 23(A), a vibration-enhancing member 5A is provided on the inner circumferential surface of the hollow shaft 5. The vibration-enhancing member 5A is formed, for example, by a coating film formed on the inner circumferential surface of the shaft 5 by plating with materials such as rhodium, copper, or gold. Alternatively, when carbon fibers are used as the vibration-enhancing member 5A, for example, multiple carbon fibers extending along the axial direction of the shaft 5 can be bundled together and formed into a shape that conforms to the inner or outer circumferential surface of the shaft 5.

[0087] In Figure 23(B), a vibration-enhancing member 5B is provided on the outer circumferential surface of the hollow shaft 5. The vibration-enhancing member 5B is formed, for example, by a coating film formed on the outer circumferential surface of the shaft 5 by plating with materials such as rhodium, copper, or gold. Alternatively, when carbon fibers are used as the vibration-enhancing member 5B, for example, multiple carbon fibers extending along the axial direction of the shaft 5 can be bundled together and formed into a shape that conforms to the inner or outer circumferential surface of the shaft 5.

[0088] The materials used for the vibration-enhancing members 5A and 5B in Figures 23(A) and (B) can be anything that enhances impact vibrations. For example, various metals such as rhodium, copper, alloys, and pure gold, or carbon fibers can be used as materials. When using carbon fibers, for example, multiple carbon fibers extending along the axial direction of the shaft 5 can be bundled together and formed into a shape that follows the inner or outer circumferential surface of the shaft 5.

[0089] The golf club 1 in Figure 24 has a vibrating plate member (not shown) that extends across the head 3, hosel 4, and shaft 5. In addition, as a striking vibration / sound enhancement mechanism, it has a vibration sensor 300 attached to the head 3 that detects vibrations generated on the striking surface 2, and an actuator 301 that vibrates based on an electrical signal output from the vibration sensor 300. The vibration of the actuator 301 is transmitted to the user by the vibrating plate member 200. In this case, since vibrations caused by electrical drive are transmitted to the user in addition to the actual striking vibration, the striking vibration can be enhanced.

[0090] Furthermore, the embodiments described above are merely examples, and the embodiments can be freely combined. Furthermore, the shape of the golf club 1 (the shape, size, and thickness of the head 3, hosel 4, and shaft 5, etc.) is not limited to the embodiments described above, but may be any well-known shape.

[0091] For example, the mounting position of the shaft 5 to the head 3 (or hosel 4) is not limited to that shown in the illustration. Specifically, the position of the shaft 5 in the front-to-back direction of the head 3 can be anywhere, such as on the front side of the head 3, on the back side, or midway between the front and back. The position of the shaft 5 in the width direction of the head 3 can be anywhere, such as on one end of the head 3 in the width direction, near the center, at the other end, on the back side, or midway between the front and back.

[0092] For example, as shown in Figure 25(A), in a golf club 1 having a shaft 5, a hosel 4, and a head 3, in addition to the diaphragm member 200 provided across the head 3, hosel 4, and shaft 5, a pickup 230, an amplifier unit 231, and a speaker 232 attached to the back side of the hosel 4 can be provided.

[0093] Furthermore, as shown in Figure 25(B), in a golf club 1 having a shaft 5, a hosel 4, and a head 3, in addition to the diaphragm member 200 provided across the head 3, hosel 4, and shaft 5, the hosel hollow portion 203 of the hosel 4 and the head hollow portion 202 of the head 3 are provided in communication with each other, and a speaker 232 can be installed inside the hosel hollow portion 203, so that the hosel hollow portion 203 is used as a speaker box and the impact sound output by the speaker 232 is emitted from the opening 203A.

[0094] As another modification, the golf club 1 shown in Figures 22(D) and (E) above may be configured to output an electronic sound from an electronic sound source based on an electrical signal detected by the pickup 230. The timbre of the electronic sound may be, for example, the timbre of an electronic drum. In other words, an electronic drum may be attached to the golf club 1. In addition, a radio, smartphone, and other devices can be detachably attached to the golf club 1.

[0095] <Plastic model kit style> Golf club 1 can be constructed as an assembly-type golf club, so to speak, a model kit type golf club, in which the user can freely select and assemble various parts such as a vibrating plate member 200, a striking surface (face), weights, balance, insert, hosel, and sub-vibrating plate member 201, with respect to the shaft 5, hosel 4, and head 3. Here, the insert may be formed integrally with the head-compatible portion 200A of the vibrating plate member 200, or it may be a separate part from the head-compatible portion 200A of the vibrating plate member 200. The head 3 and the striking surface may be formed integrally or separately. The striking surface may be formed integrally with the head-compatible portion 200A of the vibrating plate member 200, or it may be a separate part.

[0096] For example, the golf club 1 in Figures 26(A) and (B) has a vibrating plate member 200 that extends across the head 3, hosel 4, and shaft 5, and a weight 3Z that is detachably attached to the back side of the frame-shaped head 3. The golf club 1 in Figure 26(A) has weights 3Z ​​that are detachably attached to both sides of the back side of the head 3. The golf club 1 in Figure 26(B) has a vibrating plate member 200 that extends across the head 3, hosel 4, and shaft 5, and a weight 3Z that is detachably attached to the back side of the head 3, extending in a planar manner from the back to the rear. Note that the size, shape, and number of weights 3Z ​​are not limited to those described above and may be any. When diaphragm members 200 are provided, the number may be one or more. When multiple diaphragm members 200 are provided, diaphragm members 200 of various shapes can be freely combined.

[0097] The shape, size, and thickness of the diaphragm member 200 are not limited to those described above and may be any shape, size, and thickness. Figures 27(A) and (B) show modified structures in which the hosel-compatible portion 200B and shaft-compatible portion 200C of the diaphragm member 200 are integrated with the hosel 4 and shaft 5, and the head-compatible portion 200A of the diaphragm member 200 is attached to the striking surface 2 of the head 3.

[0098] The golf club 1 in Figure 27(A) differs from that in Figure 20(B) above in that the cover member 200Z is not provided and the upper edge of the head-compatible portion 200A of the vibrating plate member 200 is formed flush with the upper surface of the head 3, but otherwise they are the same. The golf club 1 in Figure 27(B) differs from that in Figure 20(A) above in that the plate member 200Y is not provided and the vibrating plate member 200 is provided without a gap in the width direction relative to the frame-shaped head 3, but otherwise they are the same.

[0099] The golf club 1 in Figure 27(C) has a structure in which the shaft-compatible portion 200C of the vibrating plate member 200 and the shaft 5 are integrated, and the head-compatible portion 200A and hosel-compatible portion 200B of the vibrating plate member 200 are attached to both the head 3 and the hosel 4.

[0100] The golf club 1 in Figures 27(D) and (E) is a modified example of a structure in which the hosel-compatible portion 200B and shaft-compatible portion 200C of the diaphragm member 200 are integrated with the hosel 4 and shaft 5, and the head-compatible portion 200A of the diaphragm member 200 is attached to the striking surface 2 of the head 3. In Figure 27(D), the upper contour of the head-compatible portion 200A of the diaphragm member 200 is semicircular when viewed from the front, and the upper part of the head-compatible portion 200A of the diaphragm member 200 protrudes above the upper part of the head 3. In the golf club 1 in Figure 27(E), the upper contour of the head-compatible portion 200A of the diaphragm member 200 is semicircular when viewed from the front, but it does not protrude above the upper part of the head 3, and the periphery of the diaphragm member 200 (top, bottom, and both sides) is surrounded by the frame-shaped head 3.

[0101] Thus, the shape (contour, thickness, etc.) of the diaphragm member 200 can be anything. The diaphragm member 200 can be a thin plate, a relatively thick plate, or an extremely thin film-like member, among other things. Furthermore, the various modifications described above may be combined as appropriate.

[0102] The material used for the diaphragm member 200 is not particularly limited. As materials, substances that can emphasize impact vibration / impact sound may be appropriately selected. Examples include various metals such as steel, alloys, pure gold, rhodium, and copper; ceramics, pottery, plastics, urethane, synthetic rubber and other synthetic resins; natural rubber (natural resin, rubber); wood; natural fibers (gut (cow, sheep intestines)); synthetic fibers (nylon fibers, polyester fibers); leather; Japanese paper; polyacetal; PET; glass; aluminum fiber; chemical fibers; resin; polypropylene; aluminum; copper; nanocellulose; paper; polyester; and more. The diaphragm member 200 may also be coated to emphasize impact vibration / impact sound.

[0103] The diaphragm member 200 is not limited to being formed from a single material, but can be formed by combining multiple materials, including the various materials exemplified above. Furthermore, the diaphragm member 200 is not limited to being formed from a single plate-shaped member, but can also be formed in a planar (membrane) shape by combining (weaving) rod-shaped or string-shaped members, for example.

[0104] Figure 28(A) is a modified version of Figure 27(A), differing in that the head 3 has a wall surface that closes its front side as the striking surface 2, and the head-compatible portion 200A of the diaphragm member 200 is attached to the back side of the striking surface 2; otherwise, it is the same. In this case, the head-compatible portion 200A of the diaphragm member 200 can be attached to and detached from the head 3 by inserting it from above the head 3 (like changing a cassette tape).

[0105] The golf club 1 in Figure 28(B) differs from that in Figure 28(A) in that the head-compatible portion 200A of the vibrating plate member 200 is built inside the head 3. As a modified example of the golf club 1 in Figure 32(B), the head-compatible portion 200A of the vibrating plate member 200 may be exposed on the front side as the striking surface.

[0106] The golf club 1 shown in Figures 29(A) and (B) has a structure in which, in addition to a vibrating plate member 200 provided across the head 3, hosel 4, and shaft 5, a horn-shaped or dome-shaped conduit 206 is carved out of the head 3.

[0107] Furthermore, the shapes of the head 3, hosel 4, and shaft 5 can be any known shape and can be freely combined. For example, the golf club 1 according to the various embodiments and modifications described above is not limited to the one in which the head 3 is connected to the straight shaft 5 via the straight hosel 4 shown in Figure 1(B), but can also be applied to the one in which the head 3 is connected to the straight shaft 5 via the crank-shaped hosel 4 shown in Figure 1(A), or to the one in which the crank-shaped shaft 5 is connected to the head 3 via the rectangular flat hosel 4. The bending direction of the crank-shaped shaft 5 or hosel 4 is not limited to bending toward the front side, but may also be bent toward one side in the width direction, for example, as shown in Figures 30(A), (B), and (C).

[0108] Figures 31(A) and (B) are cross-sectional views of a golf club 1 in which hollows are formed inside the head 3, hosel 4, and shaft 5. Although not shown, a vibrating plate member 200 is provided in the golf club 1, extending from the head 3, hosel 4, and shaft 5. Here, the hosel 4 has a hollow hosel cavity 8 inside. Similarly, the shaft 5 has a hollow shaft cavity 9 (shaft hollow section) inside, and the head 3 has a hollow head cavity 7 inside. The head cavity 7 and the shaft cavity 9 are each in communication with the hosel cavity 8.

[0109] By creating cavities inside the head 3, hosel 4, shaft 5, grip 6, etc., the vibrations of the striking surface 2 are converted into vibrations of the air inside the cavities. This allows the vibrations of the striking surface 2 to be transmitted to the user not only as physical vibrations but also as sound. In other words, the user can perceive the vibrations of the striking surface as sound, improving the feel of the shot. Furthermore, as shown by the dashed lines in Figure 31(B), an opening 11 may be formed that connects the internal space of the hosel cavity 8 to the outside of the hosel 4, a head opening 12 may be formed that connects the internal space of the head 3 to the outside, and a shaft opening 13 may be formed that connects the internal space of the shaft 5 to the outside. This can amplify the sound that reaches the user's ears, further improving the feel of the shot. The positions of the openings 11 to 13 may be on the side where the striking surface 2 is formed (front), on the opposite side (back), or on the side.

[0110] Furthermore, the hosel cavity 8, head cavity 7, and shaft cavity 9, which communicate with the openings 11-13, may be configured as resonant chambers (resonance mechanisms) that amplify the impact sound generated when the golf ball is struck within the cavities 7, 8, and 9 and transmit it to the outside through the openings 11, 12, and 13. In this way, the sound that reaches the user's ears can be made louder, further improving the feel of the shot.

[0111] In the modified examples shown in Figures 31(A) and (B), there may be only one of the openings 11 to 13, or the openings 11 to 13 may not exist at all (the openings 11 to 13 may not be formed). Furthermore, internal hollows may be selectively formed in one or more of the head 3, hosel 4, and shaft 5, rather than in all of them.

[0112] For example, the inside of the hosel 4 may be hollow and the insides of the head 3 and shaft 5 may be solid; the inside of the head 3 may be hollow and the insides of the hosel 4 and shaft 5 may be solid; the inside of the shaft 5 may be hollow and the insides of the head 3 and hosel 4 may be solid. Alternatively, the insides of the head 3 and shaft 5 may be hollow and the inside of the hosel 4 may be solid; the insides of the hosel 4 and shaft 5 may be hollow and the inside of the head 3 may be solid; the insides of the head 3 and hosel 4 may be hollow and the inside of the shaft 5 may be solid.

[0113] <Golf practice system> [1. System Configuration] Next, a golf practice system using the golf club 1 described above will be explained. In the golf practice system described below, as an example, a golf club 1 having a vibrating plate member 200 provided across the head 3, hosel 4, and shaft 5 as a striking vibration / sound enhancement mechanism will be used. However, any of the various golf clubs 1 described above may be used in this golf practice system. That is, the striking vibration / sound enhancement mechanism provided in the golf club 1 used in this golf practice system is not limited to a "vibrating plate member," but may be any of the types of striking vibration / sound enhancement mechanisms described above. In other words, the golf club 1 used in the golf practice system can be the golf club 1 described above with reference to Figures 1 to 31, or it can be the golf club 1 described later with reference to Figures 33 to 48.

[0114] Figure 32 is an explanatory diagram showing the overall configuration of the golf practice system. This golf practice system S includes a golf practice machine T for putting practice. In golf, putting, as is well known, is the act of using a golf club (typically a "putter") to hit a golf ball into a hole called a cup. The Golf Practice Machine T can be used not only for putting practice with a putter, but also for swing practice with other golf clubs such as drivers and irons.

[0115] The practice machine T includes a cup area T1 equipped with a cup C provided on the golf ball rolling surface, and a hitting area T2 located away from the cup C, which also has a golf ball rolling surface and forms the user's hitting position. The practice machine T is, for example, a practice green, in which case the cup C is recessed into the golf ball rolling surface of the cup area T1. Another example is a golf practice mat. In this case, the cup C is not recessed into the golf ball rolling surface but is provided as a predetermined area (flat surface) on the golf ball rolling surface. Also, in the case of a golf practice mat, the cup C may be formed as a shallow depression on the mat. That is, the cup C is not limited to a hole, but can be any target position for putting the golf ball into the cup. In the following description, we will mainly describe the case where the cup C is a hole recessed into the golf ball rolling surface.

[0116] The practice machine T is a facility for practicing putting by having a user (golfer) standing in the hitting area T2 use a golf club 1 to hit a ball B towards a cup C located in the cup area T1. The golf ball rolling surface is the surface on which the hit ball B rolls, and is the floor surface of the cup area T1 and the hitting area T2.

[0117] In this embodiment, the directions used to describe the golf practice system S are defined as follows: With the user putting in the hitting area T2 as the reference point, the direction from the user toward the cup C is "forward" (indicated as "F" in the diagram), the opposite side of "forward" is "backward" (indicated as "B" in the diagram), and "left" and "right" (indicated as "L" and "R" in the diagram) are determined based on "forward". In addition, "up" and "down" (indicated as "U" and "D" in the diagram) are determined based on the direction in which gravity acts.

[0118] As shown in Figure 32, the cup C provided in the cup area T1 of the training machine T is positioned in front of the hitting area T2. A pin P made of a rod-shaped member is erected on the cup C. The pin P functions as a marker for the user in the hitting area T2.

[0119] The golf practice system S shown in Figure 32 includes a cup unit 250 attached to the cup C, a pin unit 500 attached to the pin P, a club unit 700 attached to the golf club 1, and a camera unit 600 positioned in the hitting area T2.

[0120] In addition to these units 250, 500, 600, and 700, System S includes a control unit 350 that manages System S as a whole, and a user-owned terminal device 400. Each device 250, 350, 400-700 within System S is connected via a wireless communication network to enable data exchange and can operate in cooperation with each other. The wireless communication network is a network compliant with well-known wireless communication standards such as Wi-Fi and Bluetooth®.

[0121] The outline of this system S is that, based on monitoring information acquired by units 250, 500, 600, and 700, the control unit 350 generates guide information to provide guidance for the user's golf play, the control unit 350 transmits the guide information to terminal devices 400, etc., and the terminal devices 400, etc., provide guidance based on the guide information, for example, in advance before the user takes a shot. In other words, this system S provides interactive guidance for the user's golf practice through the cooperation of each device 250, 350, 400 to 700 via a network.

[0122] A guide provides users with advice and demonstrations on golf play. Specifically, this could include advice and demonstrations on things like batting form, swing rhythm, ball launch direction, and timing.

[0123] The monitoring information acquired by units 250, 500, 600, and 700 in this system S consists of measurement results related to the user's golf play. The monitoring information includes multiple video data, cup-in information, ball impact information, impact vibration / sound information associated with ball impact, and the golf club head angle. The cup unit 250, pin unit 500, club unit 700, and shooting unit 600 are monitor information sources that provide monitor information to the control unit 350.

[0124] <Cup Unit> The cup unit 250 is built into (attached to) cup C and is a mechanism provided to provide monitoring information from cup C to the control unit 350. The cup unit 250 includes a first control device (referred to as "control device" in the figure) 251, a first sensor (first detection means, referred to as "sensor" in the figure) 252, and a first communication device (first transmission device, referred to as "communication device" in the figure) 253. The first control device 251 is an electrical control device comprising a processor, a memory device, and the like, which controls the cup unit 250.

[0125] The first control device 251 is connected to the first sensor 252 and the first communication device 253 so that data can be exchanged between them. The first sensor 252 is a detection means provided to detect cup-in information indicating that golf ball B has gone into cup C. The first sensor 252 is, for example, an impact sensor that detects the impact of a golf ball B that has fallen into the cup C.

[0126] The first communication device 253 is a wireless communication device connected to the control unit 350 (external) via a wireless communication network. The cup unit 250 can transmit detection signals (cup-in information) from the first sensor 252 to the control unit 350 (external) via the first communication device 253, and can also receive information from external sources.

[0127] In addition, the cup unit 250 includes additional devices such as a camera 255 for photographing the area around cup C, an acoustic device 256 including an amplifier, speaker, and microphone, a lighting device 257, a laser irradiator 258, and a power supply (not shown) for supplying power. These devices 251-258 and various other devices not shown may be detachably attached to or integrated with the cup unit 250. Furthermore, sensors such as a speed sensor, acceleration sensor, gyro sensor, magnetic sensor, biometric authentication sensor, barometric pressure sensor, temperature sensor, microphone (sound pressure sensor), orientation sensor, proximity sensor, brightness sensor (ambient light sensor), motion sensor, anemometer, wind direction indicator, infrared sensor, infrared camera, and snow depth gauge (such as a snow depth gauge based on laser reflection or images captured by a camera) may be provided.

[0128] In other words, cup C can be configured as an "AI cup" with multiple functions, such as automatically detecting when a golf ball B goes into the cup, outputting sound, performing predetermined functions in response to predetermined voice inputs such as "Alexa®", "OK Google®", and "Hey Siri®", emitting light, and individually identifying ball B. When identifying ball B that has fallen into cup C using cup unit 250, it is preferable to brighten the inside of cup C using a light source (lighting means, lighting device 257 in Figure 32) for illuminating the inside of cup C. This improves the identifiability when identifying ball B that has fallen into cup C using the camera 255 of cup unit 250.

[0129] <Pin unit> The pin unit 500 is attached to pin P and is a mechanism provided to provide monitoring information about the area around pin P to the control unit 350. The pin unit 500 includes a second control device (referred to as "control device" in the figure) 501, a first camera (referred to as "camera" in the figure) 502, a second communication device (referred to as "communication device" in the figure) 503, a first irradiator (referred to as "laser" in the figure) 504, and a second light receiver (referred to as "light receiver" in the figure) 505.

[0130] The second control device 501 is an electrical control device that includes a processor and memory device for controlling the pin unit 500. The second control device 501 is connected to the first camera 502, the second communication device 503, the first irradiator 504, and the second photodetector 505 so that data can be exchanged between them.

[0131] The first camera 502 is an image sensor provided to capture images (first image data) of the area around pin P. In this embodiment, the first camera 502 is a shooting means that captures images at least from pin P toward the striking area T2. For example, the first camera 502 may be configured as a "360-degree camera" capable of capturing images in all 360° directions, both vertically and horizontally, centered on pin P. Note that the first camera 502 is not limited to a 360-degree camera, but may be a camera that captures a narrower range than 360 degrees. Furthermore, the first camera 502 may be configured as a 3D camera.

[0132] The second communication device 503 is a wireless communication device connected to the control unit 350 (external) via a wireless communication network. The second communication device 503 can transmit video data captured by the first camera 502 to the control unit 350 (external) and receive information from external sources.

[0133] The first irradiator 504 is a light source that emits a guide laser beam that shows a straight line from pin P to the striking area T2. The straight line indicates the rolling trajectory of ball B. The trajectory of the laser beam functions as a guide line that shows the trajectory of ball B. Here, the trajectory of ball B is the trajectory connecting cup C to a predetermined striking position. The second light receiver 505 is a light-receiving element (sensing device) for receiving (detecting) guide laser light (guide sub-laser light) from the second irradiator 705, which is located in the club unit 700 described later.

[0134] In addition, the pin unit 500 may be equipped with additional devices such as an acoustic device 506 including an amplifier, speaker, and microphone, a lighting device 507, a power supply (not shown) for supplying power, a laser irradiator, and an automatic operation mechanism for automatically operating various adjustments related to the shooting of the first camera 502 (for example, focusing, brightness adjustment, tracking of the target, switching of the shooting direction, etc.), which may be attached to or integrated with the pin unit 500. Furthermore, the sensor 508 may be equipped with, for example, a speed sensor, acceleration sensor, gyro sensor, magnetic sensor, biometric authentication sensor, barometric pressure sensor, temperature sensor, microphone (sound pressure sensor), direction sensor, proximity sensor, brightness sensor (ambient light sensor), human presence sensor, anemometer, wind direction indicator, infrared sensor, infrared camera, snow depth gauge (snow depth gauge based on laser reflection or images captured by the camera, etc.).

[0135] In other words, pin P can be configured as a multi-functional "AI pin" that can automatically capture images of the surroundings, output sound, perform predetermined functions in response to predetermined voice inputs such as "Alexa®", "OK Google®", and "Hey Siri®", emit light, and individually identify ball B. When identifying ball B that has fallen into cup C using the camera 502 of pin unit 500, it is preferable to brighten the inside of cup C with a light source (illumination means, illumination device 257 in Figure 32) attached to cup unit 250 (cup C) or the illumination device 507 of pin unit 500, as described above. This improves the identifiability when identifying ball B that has fallen into cup C using the first camera 502 or the camera 255 of cup unit 250.

[0136] Furthermore, for example, in poor visibility conditions or during nighttime golf practice (night golf), the light-emitting function (lighting device 507) attached to the pin unit 500 can be used to improve the visibility of the pin P (in other words, to provide a lighthouse function to the pin P). The lighting provided by the lighting device 507 attached to the pin P can provide, for example, illumination around the pin P, illumination, neon, lights, spotlights, rotating spotlights, mirror balls, LED lighting, etc. The lighting device 507 attached to the pin P lights up, for example, when the motion sensor included in the sensor 508 of the pin unit 500 detects a person approaching the pin P. This lighting function can be switched on and off.

[0137] <Club Unit> The club unit 700 is attached to the golf club 1 and is a mechanism provided to provide monitoring information about the golf club 1 to the control unit 350. As described above, the golf club 1 has a vibrating plate member 200 that extends across the head 3, hosel 4, and shaft 5. In other words, the club unit 700 can be mounted on either the golf club 1 described above with reference to Figures 1 to 31, or the golf club 1 described later with reference to Figures 33 to 48.

[0138] The club unit 700 includes a third control device (referred to as "control device" in the figure) 701, a second camera (referred to as "camera" in the figure) 702, a third communication device (referred to as "communication device" in the figure) 703, a second sensor (referred to as "sensor" in the figure) 704, a second irradiator (referred to as "laser" in the figure) 705, a display device (referred to as "display" in the figure) 706, an acoustic device 707, a first light receiver (referred to as "light receiver" in the figure) 708, a lighting device 709, and a striking vibration / sound sensor (referred to as "sensor #2" in the figure) 710.

[0139] The third control unit 701 is an electrical control unit comprising a processor, memory device, and other components that control the club unit 700. The third control device 701 is connected to each of the elements 702 to 710 so that data can be exchanged between them. The second camera 702 is an image sensor provided to capture images (second image data) of the area around the club 1. In this embodiment, the second camera 702 is a shooting means that captures images at least from the head of the club 1 toward the front.

[0140] The second sensor 704 is a detection means for detecting impact information related to the impact of a golf ball as one of the monitored pieces of information. The second sensor 704 is, for example, an impact sensor that detects impact data when the golf ball is struck on the impact surface, and an angle sensor that detects the angle of the head when striking the golf ball, and is built into the head 3 [Figure 1(A), etc.].

[0141] The impact vibration / impact sound sensor 710 is attached to the diaphragm member 200 (impact vibration / impact sound enhancement mechanism) provided on the golf club 1, and is a detection means for detecting impact vibration / impact sound information related to the impact vibration / impact sound enhanced by the diaphragm member 200 as one of the monitoring information. As described above, the diaphragm member 200 enhances the impact vibration generated when a golf ball is struck, and can enhance (amplify) the vibrations transmitted to the user's palm through the shaft 5 and grip 6, as well as the impact sound heard by the user (i.e., the impact sound corresponding to the impact vibration).

[0142] The impact vibration / impact sound sensor 710 consists of a vibration sensor that detects impact vibrations generated (amplified by the diaphragm member 200) in the diaphragm member 200 when, for example, a golf ball is struck. Alternatively, the impact vibration / impact sound sensor 710 consists of a pickup that detects impact sounds generated (amplified by the diaphragm member 200) in the diaphragm member 200 when, for example, a golf ball is struck. Alternatively, the impact vibration / impact sound sensor 710 may consist of a combination of a vibration sensor and a pickup. The impact vibration / impact sound sensor 710 may be built into the diaphragm member 200, for example, or disposed in the vicinity of the diaphragm member 200. The impact vibration / impact sound sensor 710 may also be built into the head 3, hosel 4, shaft 5, or grip 6.

[0143] The second irradiator 705 is a light source that emits a guide laser beam forward from the head of the golf club 1. The trajectory of the laser beam functions as a guide line indicating the trajectory of ball B. Here, the trajectory of ball B is a trajectory that is approximately perpendicular to the striking surface of the head and extends linearly forward from the striking surface.

[0144] The display device 706 is a display unit that displays visual information. An example of the display device 706 is an LCD. The sound device 707 is an audio input / output device that includes an amplifier, speaker, and microphone, and reproduces audio signals and inputs audio. The first light receiver 708 is a light-receiving element (sensing device) for receiving (detecting) guide laser light from the first irradiator 504, which is provided on the pin unit 500.

[0145] The third communication device 703 is a wireless communication device connected to the control unit 350 (external) via a wireless communication network. The third communication device 703 can transmit video data captured by the second camera 702 and detection signals from the second sensor 704 to the control unit 350 (external), and can also receive information from external sources.

[0146] In addition, the club unit 700 may be equipped with a lighting device 709, a power supply (not shown), and an automatic operation mechanism for automatically performing various adjustments related to the shooting of the second camera 702 (e.g., focusing, brightness adjustment, tracking of the target, switching of the shooting direction, etc.), which is either detachable from or integrated with the club unit 700. Furthermore, sensors such as a speed sensor, acceleration sensor, gyro sensor, magnetic sensor, biometric authentication sensor, barometric pressure sensor, temperature sensor, microphone (sound pressure sensor), direction sensor, proximity sensor, brightness sensor (ambient light sensor), motion sensor, anemometer, wind direction indicator, infrared sensor, infrared camera, and snow depth gauge (such as a snow depth gauge based on laser reflection or images captured by a camera) may be provided.

[0147] In other words, the golf club 1 can be configured as an "AI club" with multiple functions, such as automatically capturing images of the surroundings, detecting impact information, emitting laser light, outputting sound, and operating and emitting light in response to voice commands. The lighting provided by the lighting device 709 attached to the golf club 1 provides, for example, illumination, neon, lights, spotlights, rotating spotlights, mirror balls, LED lighting, etc., around the golf club 1. The lighting device 709 attached to the golf club 1 turns on, for example, when a motion sensor mounted on the golf club 1 detects a person approaching the golf club 1. This lighting function can be switched on and off.

[0148] <Photography Unit> The shooting unit 600 is attached to the hitting area T2 of the golf practice machine and is a mechanism provided to capture video of the user standing in the hitting area T2 and the surrounding area, and to provide the video data as monitor information to the control unit 350 and other devices within the system S, including the terminal device 400.

[0149] The imaging unit 600 in Figure 37 includes multiple cameras 602. Specifically, the multiple cameras 602 include a left camera 602L (one of the third imaging means) and a right camera 602R (one of the third imaging means) located on both the left and right sides of the striking area T2, a rear camera 602B (one of the third imaging means) located behind the striking area T2, and a head-mounted head camera 602H (fourth imaging means) attached to the user's head.

[0150] The left and right cameras 602L and 602R and the rear camera 602B are imaging devices that capture images (third image data) of the user from both sides and the rear. The head camera 602H is an imaging device that captures images (fourth image data) of the direction the user is looking while practicing golf. The image data captured by the imaging unit 600 is transmitted via the communication device 601 (fifth transmission device) to devices within system S, such as the control unit 350 and the terminal device 400. The shooting unit 600 includes a control device (not shown) that allows for various adjustments related to the shooting of the camera 602 (for example, focusing, brightness adjustment, tracking of the subject, switching of the shooting direction, etc.).

[0151] <Control Unit> The control unit 350 is a computer that centrally manages the system S. The control unit 350 is installed at any location, such as near the training aircraft T or at a system base located remotely from the training aircraft T.

[0152] The control unit 350 includes a control device 351, a receiving device (first receiving device, referred to as "receiving device" in the figure) 352, a first transmitting device (fourth transmitting device, referred to as "transmitting device" in the figure) 353, and a storage device 354. The receiving device 352 and the transmitting device 353 are devices for exchanging data with the outside world via a wireless communication network.

[0153] The control unit 350 receives various video data and sensor detection data acquired by each unit 250, 500, 600, and 700 within the system S as monitor information via the receiving device 352. The control device 351 is a device that generates predetermined guide information based on the above-mentioned monitoring information, and is, for example, a processor that implements a software program for generating guide information. The guide information is information that provides the user with guidance for playing golf as described above.

[0154] The storage device 354 is a storage device for storing various types of data. The storage device 354 includes a temporary storage device for temporarily storing received monitor information, as well as a database in which a history of monitor information over a certain period is stored and associated with each user's ID information. The history of monitor information is treated as so-called "big data."

[0155] In addition to monitor information, various other types of information are also stored in the memory device 354. Other types of information stored in the memory device include practice machine information such as the slope and grain of the golf practice machine T on which this system S is used, and personal information such as the user's age, gender, and golf skill level. When generating guide information, the control device 351 may take into account not only the received monitor information but also the history and other information mentioned above. This increases the amount and types of information taken into account when generating guide information, thereby enabling the provision of higher quality guides to the user.

[0156] The transmitting device 353 transmits the guide information generated by the control device 351 to the terminal device 400. Furthermore, the transmitting device 353 may transmit guide information to at least one of the cup unit 250, pin unit 500, club unit 700, and imaging unit 600 (i.e., any device in system S) in addition to or instead of the terminal device 400. Furthermore, various functions of the control unit 350, including the process of generating guide information in the control device 351, may be provided by cloud computing using computing services on a cloud environment (Internet environment).

[0157] <Terminal device> The terminal device 400 is a portable information terminal device that can be carried by the user. The terminal device 400 includes a fourth control device (referred to as "control device" in the figure) 401, a display device 402 (presenter, referred to as "display (presenter) device" in Figure 32), a fourth communication device (second receiving device, referred to as "communication device" in the figure) 403, and an input device 404. The fourth control device 401 is an electrical control device comprising a processor and memory device, etc., which implement a software program for the overall control of the terminal device 400.

[0158] The fourth communication device 403 is a wireless communication device connected to the control unit 350 (external) via a wireless communication network. Guide information can be received from the control unit 350 and various types of information can be transmitted externally via the fourth communication device 403.

[0159] The display unit 402 is an example of a presenter that displays (presents) guides based on guide information to the user using some kind of visual image, such as moving images or still images. An example of the display unit 402 is an LCD. The input device 404 is, for example, a touch panel sensor or a button switch.

[0160] Examples of display devices other than the display unit 402 include an acoustic device 405 that outputs sound, a light-emitting illuminator (not shown), and a vibration generating mechanism (not shown) that generates vibration. When an audio device is used as a guide, it presents guidance for golf play using, for example, music, voice, electronic sounds, sound effects, or other sounds. When a lighting device is used as a guide, it displays the guide or support content by flashing lights or changing the color of the light. In the case of a vibration generating mechanism, it presents guidance for golf play through vibration.

[0161] In addition, the terminal device 400 may have various sensors built in. Examples of sensors include gyro sensors, magnetic sensors, GPS, biometric authentication sensors, radar sensors, barometric pressure sensors, temperature and humidity sensors, microphones (sound pressure sensors), compass sensors, proximity sensors, brightness sensors (ambient light sensors), image sensors (camera 406), vital sensors, pulse sensors, body temperature sensors, moisture level sensors, blood pressure sensors, distance sensors, tilt sensors, terrain sensors, motion sensors, anemometers, wind vanes, infrared sensors, infrared cameras, and snow depth gauges (such as snow depth gauges based on laser reflection or images captured by cameras).

[0162] Portable devices used in terminal device 400 include portable information terminal devices such as smartphones and tablet devices, as well as wearable devices that can be worn by the user. In addition, terminal device 400 may also be a well-known golf rangefinder that uses a laser to measure the distance from the user to the target. From the perspective of achieving a balance between golf play and display viewing, it is preferable to use a wearable terminal for the terminal device 400.

[0163] Examples of wearable devices include smart glasses, eyeglass-type wearable devices, and smartwatches. Among wearable devices, head-mounted wearable devices such as smart glasses and eyeglasses are preferable because they allow golfers to view guides and support content without interrupting their golf game.

[0164] When a head-mounted wearable terminal is used as the terminal device 400, the head camera 602H of the imaging unit 600 is composed of a camera 406 equipped on the head-mounted wearable terminal used as the terminal device 400. In addition, the terminal device 400 may also include an audio device (audio input / output device) 405, including earphones, headphones, microphones, etc.

[0165] Furthermore, the terminal device 400 can be equipped with an executable application program for performing the functions of the control unit 350 described above (such as the overall management function of system S, the function of generating and providing guide information, etc.). In this case, the terminal device 400 can perform the overall management function of system S, the function of generating and providing guide information, etc., together with or in place of the control unit 350.

[0166] [2. Control] Next, we will describe a specific example of the control that provides guidance in this system S. In the control unit 350, the control device 351 constantly receives as monitoring information video data acquired from the camera 255 of the cup unit 250, the first camera 502 of the pin unit 500, the cameras 602L, 602R, 602B, and 602H of the shooting unit 600, and the second camera 702 of the club unit 700, as well as cup-in information from the first sensor 252 of the cup unit 250, impact information from the impact sensor and angle data from the angle sensor included in the second sensor 704 of the club unit 700, and impact vibration / impact sound information from the impact vibration / impact sound sensor 710 of the club unit 700.

[0167] The control device 351 stores the received video data, cup-in information, impact information, angle data, and impact vibration / impact sound information (monitor information) in a storage device and accumulates them as big data. Based on this monitor information, it also generates guide information to provide guidance to the user's golf play.

[0168] <Guide presentation> First, let's look at an example of a control that provides guidance on playing golf. The control device 351 analyzes video data acquired using well-known image analysis techniques to calculate estimated play status data. Estimated play status data is data estimated from the video to determine the current play status. The estimated data includes, for example, the user's current position, the user's posture before the swing, head-up analysis, head-up check, the user's eye level, head position, stance, and distance to the pin. Based on the estimated play status data, the control unit 350 can grasp (estimate) the play status based on the monitor information.

[0169] The control device 351 generates guide information based on the calculated estimated play situation data and sample (exemplary play) data. The guide information is advice (guide) to achieve better shots in relation to the current play situation (user's current position, user's posture before the swing, head-up analysis, head-up check, user's eye position, head position, stance, distance to the pin, etc.).

[0170] Specifically, this involves presenting golf play tips such as exemplary swing path, exemplary form, swing rhythm, ball launch direction, stance, foot width, and accurate impact using illustrations, photographs, videos, audio, rhythm sounds, or text. In addition, the playing forms of masters and experts, such as professional golfers, can also be presented as exemplary play.

[0171] The storage device 354 pre-stores exemplary data that serves as a guide for golf play, as well as various video, image, and audio data for generating guide information. Examples of exemplary data include the user's posture before the swing, the position of the user's eyes, the position of their head, their stance, how to move their body, and the trajectory of the golf club.

[0172] The control device 351 transmits the generated guide information to the terminal device 400. The terminal device 400 outputs golf play guide content based on the guide information from the display 402 and the sound device 405. In addition to the terminal device 400, the destination of the guide information may also be the display device 706 and sound device 707 of the club unit 700, or other units 250, 500, etc.

[0173] Guide content consists of at least one of guide video and guide audio. The guide videos cover aspects such as the user's eye position, head position, posture, head-up analysis, head-up check, hitting form, golf club stroke trajectory, head angle, ball launch angle, head speed, impact strength, swing tempo, grab path (trajectory), and putter face direction (angle).

[0174] Guide audio may include a metronome sound (including music, voice, and other rhythmic sounds) to guide the swing rhythm of the golf club, and advice (voice comments) to improve golf play. Alternatively, users may connect to interactive online golf lesson services via the internet.

[0175] As a guide for playing golf, you may present predicted outcomes based on the current playing situation. These predicted outcomes may include, for example, the expected ball trajectory, the expected swing path, and the expected form.

[0176] The control device 351 can take into account monitor information accumulated as big data, practice range information such as the slope and grain of the green, and personal information such as the user's age, gender, build, constitution, height, weight, and golf skill level when generating guide information. By taking into account various types of information, the accuracy of the golf play guidance provided by the guide information can be improved. Furthermore, by incorporating the user's golf play history into the guide information, the user's "habits" can be more easily reflected, and personalized golf play guidance can be provided. In addition, the control device 301 may have a function (generation AI) that learns from various collected and accumulated data and automatically generates guide information.

[0177] <Laser light guidance> In this system S, a laser beam (guide laser beam) is emitted from the first irradiator 504 of the pin unit 500 toward the hitting area T2. Meanwhile, the club unit 700 of the golf club 1 used by the user in the hitting area T2 is equipped with a first receiver 708. Therefore, when the user stands in the appropriate position relative to the pin unit 500, the first receiver 708 of the club unit 700 receives the laser beam from the first irradiator 504. When the first receiver 708 receives the guide laser beam, the display in the system S indicates this.

[0178] Examples of indicators include the indicator 402 of the terminal device 400 and the display device 706 of the club unit 700. Furthermore, when the first light receiver 708 receives the guide laser light, it may be announced via audio output from a speaker within the system S. Speakers within the system S include the sound device 405 of the terminal device 400, the sound device 256 of cup C, the sound device 506 of pin P, and the sound device 707 of the club unit 700.

[0179] Furthermore, a laser beam (guide sub-laser beam) is emitted from the second irradiator 705 of the club unit 700. When the user is standing in the correct position relative to pin P, this laser beam from the second irradiator 705 is directed towards pin P (pin unit 500). On the other hand, the pin unit 500 is equipped with a second receiver 505. Therefore, when the user stands in the correct position relative to the pin unit 500, the second receiver 505 of the pin unit 500 receives the laser beam from the second irradiator 705 of the club unit 700.

[0180] When the second receiver 505 receives the guide sub-laser light, a display unit in the system S indicates this. Examples of displays include the display unit 402 of the terminal device 400 and the display device 706 of the club unit 700. Alternatively, when the second receiver 505 receives the guide sub-laser light, a speaker in the system S may announce this via audio output. Speakers in the system S include the sound device 405 of the terminal device 400, the sound device 256 of cup C, the sound device 506 of pin P, and the sound device 707 of the club unit 700.

[0181] As described above, when the first receiver 708 receives the guide laser beam, the display in the system S displays a message to that effect, and when the second receiver 505 receives the guide sub-laser beam, the display in the system S displays a message to that effect. This configuration allows the user to confirm through the display that they are standing in the correct position relative to the pin unit 500. The displayed content can be anything as long as it informs the user that they are standing in the correct position relative to the pin unit 500. The trajectories of the laser beam from the first receiver 708 and the laser beam from the second receiver 505 function as guide lines indicating the trajectory of ball B, allowing the user to stand in the appropriate position relative to the pin unit 500 and understand the launch direction of ball B. Thus, a visual guide regarding putting (hitting ball B) can be provided to the user.

[0182] Furthermore, by using the first irradiator 504 of the pin unit 500 and the second irradiator 705 of the club unit 700, it is possible to provide bidirectional guide light using laser light from the front and laser light from the rear. Bidirectional guide light can provide more reliable guidance. The irradiation angles of the first irradiator 504 of the pin unit 500 and the second irradiator 705 of the club unit 700 can be automatically adjusted based on the analysis results of the monitor information and video data mentioned above. This allows for adjustment of the direction of the laser beam, enabling accurate guidance that reflects the current playing situation.

[0183] <Feedback on the results of the current situation analysis> Furthermore, the control device 351 can provide feedback on the play result after the hit is finished, based on the results of analyzing the video data. In this case, the control device 351 identifies the swing performed by the user in the video based on the results of analyzing the video data, analyzes the identified swing, and tracks the struck golf ball B in the video to analyze the movement of the golf ball B. Here, analyzing and evaluating the swing includes analyzing the user's form and analyzing the movement of the golf club (head).

[0184] Examples of analysis items for user form include the user's eye position, head position, posture, head-up analysis, and head-up check. Examples of analysis items related to the movement of the golf club (head) include the golf club stroke trajectory, head angle, head speed, force of impact, putter face angle, ball launch angle, club path (in-out / out-in movement of the club head at impact), swing tempo, swing flow, and club head movement.

[0185] Examples of analysis items for the movement of golf ball B include the speed of golf ball B, the launch angle (direction) of golf ball B, and the distance golf ball B travels. The control device 351 calculates analysis result data for each of the above items by analyzing the video data, and generates the calculated analysis result data as support information for practice. The analysis results data generated as support information will be used to display the analysis results and evaluations of golf play for each of the above items.

[0186] The control device 351 transmits the analysis result data generated as support information to the terminal device 400. The fourth control device 401 of the terminal device 400 displays the analysis results and evaluations of the golf play for each of the above items on the display device 402 as support content for practice, based on the received analysis result data (support information). In other words, feedback on the results of golf play is provided. Such feedback contributes to improving the user's golf skills. Furthermore, the visualization of one's own play as numerical data and images also contributes to enhancing the enjoyment of golf.

[0187] Examples of golf play analysis results displayed as support content on display unit 402 are listed below. These include the speed of golf ball B, the launch angle (launch direction) of golf ball B, the distance of golf ball B, the spin rate of ball B, the spin direction of ball B, the spin speed, ball quality, spin quality, a video recording of the user's form during the swing, a series of high-speed photographs of the user's form during the swing, the user's eye position, head position, posture during the swing, head-up analysis, head-up check, golf club stroke trajectory, measured head angle, measured head speed, measured impact strength, swing tempo, swing flow, and club head movement. The golf club stroke trajectory includes the so-called grab path. The head angle includes the orientation (angle) of the putter face.

[0188] Feedback on golf play results is not limited to visual feedback as described above; it may also be provided through audio information (i.e., auditory feedback). Auditory feedback specifically refers to communicating the results of a golf play analysis via voice. Specifically, this could include outputting voice messages such as "Nice shot," "Wavy," "Hooked," "Open," "Wavy by n degrees," "Hooked by n degrees," or "Open by n degrees" in response to the user's swing. These voice messages can be combined with the visual feedback mentioned above.

[0189] In this case, the storage device 354 of the control unit 350 is provided with a database that stores various audio data used for auditory feedback. The control device 351 extracts audio data to be provided to the user from the database based on the various analysis result data calculated, and generates practice support information that includes this audio data.

[0190] The terminal device 400 outputs audio based on the transmitted audio data. Headphones or earphones can be used for audio output, for example. However, audio output is not limited to the terminal device 400; any audio device within the system S may also perform the audio output.

[0191] <Banner Ad> The control device 351 may generate banner advertisement display information in conjunction with providing the above-mentioned guide information and feedback on golf play results, and transmit it to the user's terminal device 400.

[0192] Banner ad display information is information for displaying banner ad videos (small advertisements displayed on a portion of the screen). In this case, the terminal device 400 displays banner ads in conjunction with the provision of guide information and feedback on golf play results. The banner advertisement may be displayed on any display device within the system S, in addition to the terminal device 400.

[0193] The control device 351 may generate advertising audio output information in place of, or in addition to, the banner advertising information and transmit it to the user's terminal device 400. In this case, the terminal device 400 outputs the advertising audio along with the feedback on the golf play results. The output video and audio content is not limited to advertisements; it can be any video or audio (such as ASMR).

[0194] Furthermore, the content provided by this system S from the control unit 350 to the terminal device 400 and other devices 250, 500, and 700 is not limited to the above. For example, the following may be provided: audio or video announcements for "prize giveaways," advertising videos, advertising audio, point rewards at shops and websites, miles, mileage, stay mileage, discount tickets, service vouchers, music, support audio, lighting effects, etc.

[0195] In this case, the control unit 350's storage device 354 is equipped with a database that stores a large amount of information (including advertising video signals) related to advertising videos, advertising audio, point accrual at shops and websites, music, support audio, lighting effects, etc. For example, in response to a cup-in, the control unit 350 extracts information related to advertising videos, advertising audio, point accrual at shops and websites, miles, mileage, stay mileage, discount tickets, service vouchers, music, support audio, lighting effects, etc. from the database and transmits it to the terminal device 400.

[0196] Furthermore, the support sounds are designed to enhance the enjoyment of golf, specifically including sounds such as gallery cheers, shouts, and applause. The lighting effects enhance the user's enjoyment of golf by controlling the on / off, color, and brightness of the light sources within System S. The lighting provides illuminations, neon lights, spotlights, rotating spotlights, mirror balls, LED lighting, etc. The lighting effects may be accompanied by music playback. Users can select their desired music genre and song, such as disco, club music, classical music, popular songs, or enka. The lighting effects should change the control of the light sources according to the selected music genre.

[0197] The timing of providing banner ads, advertising audio, music, etc., is not limited to when a ball is put in the cup. Advertising videos, advertising audio, music, radio broadcasts, movies, etc., can be provided at any time while practicing with the practice machine T. The provision of "music" mentioned above includes playing music based on playlists of desired genres or songs created by the user, or playing music selected by a DJ (disc jockey). Regarding the DJ's selection, the user may request their desired songs. The music provided may also be so-called "karaoke." In this case, the user can sing along to the karaoke performance.

[0198] Users can arbitrarily switch on and off the playback of audio and video content such as advertising videos, advertising audio, music, radio broadcasts, movies, television, and video streaming services. In other words, whether or not the various contents mentioned above are provided can be individually selected by the user from, for example, the terminal device 400.

[0199] In addition, the terminal device 400 may provide features such as competitive games linked to the acquired monitor information, putting games, and approach games. If the user's terminal device 400 is a wearable device that is worn on the head, such as smart glasses or glasses-type wearable devices (head-mounted wearable device), the various guides and support content images mentioned above will be superimposed onto the real world and displayed on the display unit 402 of the terminal device 400. By providing guides and support content using AR (Augmented Reality), VR (Virtual Reality), or MR (Mixed Reality), the user's enjoyment of playing golf can be further enhanced.

[0200] If the user's terminal device 400 is a wearable device worn on the head, such as smart glasses or glasses-type wearable devices (head-mounted wearable device), the user can use the display 402 of the terminal device 400 to play audio and video such as advertising videos, advertising audio, music, radio broadcasts, and movies, as well as browse websites and view various file documents while playing golf or moving between courses. In other words, the user can have auditory and visual experiences or perform auditory and visual tasks unrelated to golf while playing golf. The user can select the various guides and support content mentioned above from the terminal device 400 as appropriate and receive support content in their desired combination.

[0201] Furthermore, the analysis results of the video data and the generated support information may be stored as big data in the storage device of the control device 351 (control unit 350). By saving the analysis results of the video data and the generated support information as big data in the control unit 350, a data spreadsheet containing golf play information can be provided. This big data can be mutually utilized by multiple golf practice machines.

[0202] In the golf practice system S shown in Figure 32, a user display (monitor) 1M is installed in the hitting area T2. This monitor 1M is an example of a display device for showing various information and is installed near the user. The monitor 1M is equipped with a control device 901, a display device 902, a communication device 903, an input device 904, an acoustic device 905, a camera 906, a sensor 907, a lighting device 908, etc. As sensors, for example, a speed sensor, an acceleration sensor, a gyroscope, a magnetic sensor, a biometric authentication sensor, a barometric pressure sensor, a temperature sensor, a microphone (sound pressure sensor), a compass sensor, a proximity sensor, a brightness sensor (ambient light sensor), a human presence sensor, an anemometer, a wind vane, an infrared sensor, an infrared camera, a snow depth gauge (such as a snow depth gauge based on laser reflection or images captured by a camera), etc.

[0203] In other words, Monitor 1M functions as one of the devices within the training system S, and can be configured as a multi-functional AI device that can cooperate with other devices within the system S, display various information to the user, output sound, perform predetermined functions in response to predetermined voice inputs such as "Alexa®", "OK Google®", and "Hey Siri®", and also emit light.

[0204] Monitor 1M may display various guides, support content, video and still images of the user's form, as well as weather, current events, the user's score, and ranking. Monitor 1M allows the user to easily check the visual information provided by System S. In addition, Monitor 1M functions as an element within the golf practice system S in conjunction with other devices within System S. For example, the user may use Monitor 1M to connect to an interactive online golf lesson service via the internet.

[0205] Furthermore, an electronic display board 800 (showing device) may be installed at any location within the golf practice system S (for example, behind the cup area T1). The electronic display board 800 is an example of a showing device for displaying various information within the golf practice system S, and from the viewpoint of ensuring visibility, it is preferably a large display device. However, the size of the electronic display board 800 is not particularly limited. The electronic display board 800 may be configured as an information terminal device equipped with attached mechanisms such as a control device 801, a display device 802, a communication device 803, an input device 804, an acoustic device 805, a camera 806, a sensor 807, and a lighting device 808, and can function as one of the devices that make up the system S.

[0206] Sensors 807 may include, for example, a speed sensor, acceleration sensor, gyroscope, magnetic sensor, biometric authentication sensor, barometric pressure sensor, temperature sensor, microphone (sound pressure sensor), compass sensor, proximity sensor, brightness sensor (ambient light sensor), motion sensor, anemometer, wind vane, infrared sensor, infrared camera, snow depth gauge (such as a snow depth gauge based on laser reflection or images captured by a camera). In other words, the electronic display board 800 functions as one of the devices in the training system S and can be configured as a multi-functional AI device that can cooperate with other devices in the training system S, display various information to the user, output sound, perform predetermined functions or light up in response to predetermined voice inputs such as "Alexa®", "OK Google®", and "Hey Siri®".

[0207] The display of various information on the electronic display board 800 is controlled, for example, by the control unit 350. The electronic display board 800 may be controlled not only by the control unit 350, but also by any of the cup unit 250, control unit 350, terminal device 400, pin unit 500, shooting unit 600, or club unit 700 within the system S. The electronic display board 800 may display the various guides and support content described above. In addition to the guides and content described above, any information such as weather, current events, user scores, and rankings may be displayed on the electronic display board 800. Alternatively, a projector may be provided instead of, or in addition to, the electronic display board 800. The projector can project images using projection mapping into the system S.

[0208] All cameras installed within the golf practice system S may be composed of 3D cameras. Furthermore, each device within the golf practice system S may be configured to share its respective power status (e.g., battery level) and operating status (instruments).

[0209] Furthermore, since the shooting unit 600 is positioned to surround the user standing in the hitting area T2, the shooting unit 600 can capture a full-body (all-around) image of the user. This image information can be used to obtain measurement data for custom-made golf wear, golf caps, golf shoes, golf clubs, and other clothing, accessories, and equipment. This image information can also be used to create icons, avatars, and characters (two-dimensional characters, three-dimensional characters) for use on social networking services (SNS) and other online platforms. The created avatars can be used in a three-dimensional virtual space constructed on a computer, such as a metaverse.

[0210] [3. Effects and Benefits] The golf practice system S of this embodiment has the above-described configuration and therefore produces the following effects.

[0211] According to this system S, at least one of the following is acquired as monitor information: cup-in information from the first sensor 252 of the cup unit 250, video data captured by the first camera 502 of the pin unit 500 from the pin P toward the hitting area T2 (rear), video data captured by the second camera 702 of the club unit 700 from the head toward the front, impact data and head angle data detected by the second sensor 704 of the club unit 700, and impact vibration / impact sound information detected by the impact vibration / impact sound sensor of the club unit 700. The control unit 350 grasps the current playing situation based on the monitor information and generates guide information to provide guidance to the user's golf play according to the playing situation. The terminal device 400 provides the user with guidance according to the guide information in advance before the user makes a shot.

[0212] The training machine T provides guidance based on monitor information obtained from multiple monitor information sources (cup unit 250, pin unit 500, club unit 700) positioned in front (cup C side) and behind (hitting area T2 side). The monitor information includes multiple types, such as video data, hitting information, vibration information, and cup-in information. Therefore, a highly accurate guide that takes into account numerous factors is provided, thereby enhancing the effectiveness of practice.

[0213] Here, since the monitor information includes impact vibration / impact sound information related to the (enhanced) impact vibration / impact sound generated by the diaphragm member 200, it becomes possible to provide guidance based on the impact vibration / impact sound information. For example, the correlation between the impact vibration / impact sound information and impact information (other monitor information) (e.g., the relationship between impact vibration or impact sound and the quality of the impact) can be analyzed and the analysis results can be presented, or these analysis results can be accumulated and fed back to the user. In addition, the impact vibration / impact sound information can be visualized using numerical values ​​or graphs, or the impact vibration / impact sound information can be accumulated as big data.

[0214] Furthermore, by using the first irradiator 504 of the pin unit 500 and the second irradiator 705 of the club unit 700, it is possible to present guide light in both directions using laser light from the front and laser light from the rear. Therefore, compared to a structure that irradiates guide light in one direction from the golf club, more accurate guidance is possible.

[0215] Figures 33(A) and (B) show a side view of golf club 1. The golf club 1 shown in Figure 33(A) is provided with a vibrating plate member 200 extending from the head 3 through the hosel 4 to the shaft 5. The hosel 4 has two bends, and its bent shape is such that the upper end on the shaft 5 side is located further forward than the lower end on the head 3 side. Here, the head-compatible portion 200A of the vibrating plate member 200 is attached to the striking surface 2 of the head 3, and the hosel-compatible portion 200B of the vibrating plate member 200 is attached to the front-facing surface of the hosel 4. The shaft-compatible portion 200C of the vibrating plate member 200 is attached to the front-facing surface of the shaft 5. In other words, the vibrating plate member 200 can be retrofitted to the golf club 1 and is also detachable from the golf club 1.

[0216] The golf club 1 shown in Figure 33(C) is a perspective view of the golf club 1 in Figure 33(A), and shows the golf club 1 and the vibrating plate member 200 in disassembled form. In any golf club 1, not limited to the golf club 1 shown in Figure 33(A), the thickness of the vibrating plate member 200 can be appropriately set, and it may be made thicker or thinner. Furthermore, the golf club 1 may be provided with both a vibrating plate member 200 and a balance member (weight). The balance of the golf club 1 may also be adjusted by the weight of the vibrating plate member 200. In this case, the vibrating plate member 200 also serves as a balance adjustment function (weight).

[0217] In the golf club 1 shown in FIG. 33(B), the head 3 is formed with a reduced thickness on the side where the hitting face 2 is located. By forming the head 3 with a reduced thickness on the side where the hitting face 2 is located, the hitting face 2 of the head 3 itself exhibits a function of emphasizing the hitting vibration and hitting sound generated during the hitting of a golf ball. That is, the hitting face 2 of the head 3 functions as a diaphragm member 200. In other words, the head-corresponding portion 200A of the diaphragm member 200 is integrally formed with the head 3 in a state where it cannot be replaced. Also in this case, the hitting feeling and hitting sound can be improved as compared with existing golf clubs. In the golf club 1 shown in FIG. 33(B), a weight may be attached to the head 3 to adjust the balance.

[0218] Further, the golf club 1 shown in FIG. 33(D) is an exploded perspective view showing a modified example of the golf club 1 shown in FIG. 33(C). The golf club 1 shown in FIG. 33(D) is different from the golf club 1 shown in FIG. 33(C) in that the hosel 4 extends linearly, and the other components are commonly configured.

[0219] In the golf club 1 shown in FIG. 34(A), a diaphragm member 200 is provided extending from the head 3 through the hosel 4 to the shaft 5. The head-corresponding portion 200A of the diaphragm member 200 has a first surface portion attached to the hitting face 2 of the head 3, and the hosel-corresponding portion 200B of the diaphragm member 200 has a second surface portion extending upward from the first surface portion 200A. The hosel-corresponding portion 200B (second surface portion) of the diaphragm member 200 is integrally formed with the hosel 4.

[0220] This hosel 4 has two bent portions and is formed in a bent shape such that the upper end portion on the shaft 5 side is located forward of the lower end portion on the head 3 side. The head-corresponding portion 200A (first surface portion) of the diaphragm member 200 is the hitting face of the head 3 and also functions as a so-called insert.

[0221] The golf club 1 shown in FIG. 34(B) is different from the golf club 1 shown in FIG. 34(A) in that the head-corresponding portion (first surface portion) 200A and the hosel-corresponding portion (second surface portion) 200B of the diaphragm member 200 are formed as separate members, and the rest is common. Note that the shaft-corresponding portion 200C of the diaphragm member 200 is attached to the front surface of the shaft 5, and the head-corresponding portion 200A, the hosel-corresponding portion 200B, and the shaft-corresponding portion 200C of the diaphragm member 200 are connected to each other.

[0222] The hosel 4 of the golf club 1 shown in FIG. 34(C) has two bent portions and has a bent shape in which the upper end portion on the shaft 5 side is located in front of the lower end portion on the head 3 side, and has a triangular thin plate-like portion 4T erected from the upper surface of the head 3. The head-corresponding portion 200A of the diaphragm member 200 has a first surface portion attached to the striking surface 2 of the head 3. The hosel-corresponding portion 200B of the diaphragm member 200 has a second surface portion bonded to the front surface of the thin plate-like portion 4T of the hosel 4. That is, the hosel-corresponding portion 200B (second surface portion) of the diaphragm member 200 has a fin-like portion formed of a triangular thin plate provided between the head 3 and the hosel 4.

[0223] The second surface portion (fin-like portion), which is the hosel-corresponding portion 200B of the diaphragm member 200, may be provided integrally with the thin plate-like portion 4T of the hosel 4, or may be detachable (retrofit possible) with respect to the thin plate-like portion 4T of the hosel 4. In this case, the head-corresponding portion 200A (first surface portion) of the diaphragm member 200 also functions as a so-called insert. The head-corresponding portion 200A (second surface portion) of the diaphragm member 200 functions as a so-called fin.

[0224] Note that the thickness of the thin plate-like portion 4T may be set to be thin so that the thin plate-like portion 4T itself also functions as a fin-like portion. Furthermore, as shown by the dashed line in Figure 34(C), the lighting member 4E may be arranged in a planar or chain-like manner on the top surface of the second surface portion 200B (head-corresponding portion, fin-shaped portion) and the thin plate-shaped portion 4T. The lighting member 4E may be arranged on only one of the second surface portion 200B and the thin plate-shaped portion 4T.

[0225] Furthermore, the shaft-compatible portion 200C of the diaphragm member 200 is attached to the front surface of the shaft 5, and the head-compatible portion 200A, hosel-compatible portion 200B, and shaft-compatible portion 200C of the diaphragm member 200 are connected to each other. In Figures 34(A) to (C), the shape of the hosel 4 (neck shape) is not limited to the example shown, and any well-known shape such as a straight neck, gooseneck, or crank neck can be freely applied.

[0226] In addition to the vibrating plate member 200 provided across the head 3, hosel 4, and shaft 5 of the golf club 1 shown in Figure 35(A), a detachable unit 70 is detachably installed in the shaft cavity 9 and the grip cavity 10. The detachable unit 70 is provided with a main body portion 70A and a hollow portion 70B formed inside the main body portion 70A. The main body portion 70A extends in the direction in which the shaft 5 extends (axial direction) and is a cylindrical member that conforms to the inner circumference shape of the shaft cavity portion 9 and the grip cavity portion 10.

[0227] The shape of the main body 70A of the detachable unit 70 can be any shape as long as it is cylindrical, following the inner circumference shape of the shaft cavity 9 and the grip cavity 10, and has a hollow section 70B formed inside. As an example, as shown in Figure 35(B), the main body 70A forms a frame structure combining a plurality of vertical beams 70V extending along the axial direction of the shaft 5 and a plurality of horizontal beams 70H along the axial cross section. Each vertical beam 70V is arranged spaced apart from each other between its upper end 70U and lower end 70D. Each horizontal beam 70H is arranged perpendicular to each vertical beam 70V. Each vertical beam 70V and each horizontal beam 70H forms a lattice-like frame structure.

[0228] The main body 70A (detachable unit 70) functions as a reinforcing member that strengthens the shaft 5 from the inner circumferential surface side. By reinforcing the strength of the shaft 5 with the main body 70A (detachable unit 70), the thickness of the circumferential surface of the shaft 5 (the circumferential surface surrounding the shaft cavity 9) can be reduced. As a result, the shaft 5 becomes more permeable to vibration transmission, thereby strengthening the vibrations transmitted to the grip 6.

[0229] As a modified example of the main body 70A (detachable unit 70) shown in Figure 35(B), the main body 70A may be constructed with one or more vertical beams 70V by omitting the horizontal beam 70H. The shape of the main body 70A is not limited to the frame structure described above; it may also be a cylindrical structure surrounded by walls. Furthermore, it is not limited to a cylindrical shape; it may also be a rectangular tube.

[0230] The detachable unit 70 shown in Figures 35(A) and (B) is cylindrical in shape, conforming to the inner circumference of the shaft cavity 9 and the grip cavity 10, and can be described as a cartridge type that is inserted into and removed from the shaft cavity 9 and the grip cavity 10. In this case, the golf club 1 can be described as having a double structure with the detachable unit 70 built inside. Figure 35(C) shows a modified example of the shape of the detachable unit 70. The shape of the detachable unit 70 shown in Figure 35(C) is a capsule shape with both the upper and lower ends being approximately hemispherical. The shape of the detachable unit 70 shown in Figure 35(D) is a modified example of the capsule shape, in which the lower end (one end) is a curved surface that is more pointed than the upper end (the other end).

[0231] The detachable unit 70 shown in Figures 35(A) to (D) may be detachably mounted with its lower end in contact with the hosel 4, or it may be built into the shaft cavity 9 and the grip cavity 10 at a distance above the hosel 4. The detachable unit 70 shown in Figures 35(A) to (D) may have its upper end housed in the grip cavity 10 or in the shaft cavity 9. The upper end of the detachable unit 70 may be located at the upper end of the grip cavity 10 or the shaft cavity 9, or it may be located below the upper end of the grip cavity 10 or the shaft cavity 9.

[0232] The outer circumferential surface of the detachable unit 70 may or may not be in contact with the inner circumferential surfaces of the shaft cavity 9 and the grip cavity 10. If the outer circumferential surface of the detachable unit 70 is not in contact with the inner circumferential surfaces of the shaft cavity 9 and the grip cavity 10, for example, a resin ring may be provided on the outer circumferential surface of the detachable unit 70 to seal the gap between it and the inner circumferential surfaces of the shaft cavity 9 and the grip cavity 10.

[0233] The detachable unit 70 may incorporate various electrical devices 72 such as a pickup, amplifier, speaker, microphone, actuator, communication device, battery, and motor. For example, if a sensor is provided on the detachable unit 70, it is possible to detect information within the shaft 5. Specifically, if a vibration sensor is provided on the detachable unit 70, it is possible to detect vibration information within the shaft 5. This information within the shaft 5 can be used, for example, as one of the pieces of information handled in the golf practice system described above.

[0234] The diaphragm member 200 may have a structure that easily generates sound in response to impact, a structure similar to that of a percussion instrument. In this case, the structure of various percussion instruments such as steelpans, gongs, drums, and cymbals can be applied to the diaphragm member 200. The diaphragm member 200 may be added to the golf club 1 afterwards, or it may be a pre-installed part (original equipment) on the golf club 1. In addition, in each of the above embodiments and modifications, the shape of the hosel 4 and shaft 5 (neck shape) is not limited to those described above, and any well-known shape such as a straight neck, gooseneck, or crank neck can be freely applied. Furthermore, in each of the above embodiments and modifications, the golf club is not limited to a putter; it may be any type, such as an iron or a driver.

[0235] Figures 36-39 show a golf club 1 characterized by a surface vibrating member (insert) provided on the striking surface 2 of the head 3. As shown in Figure 36, this golf club 1 comprises a head 3, a hosel 4, a shaft 5, and a grip 6. The side of the head 3 is provided with a striking surface (face) 2 for striking the golf ball. The striking surface 2 is equipped with an insert consisting of a surface vibration member 15 that is formed in a planar shape and vibrates upon impact with the golf ball, and also provides a reaction force to the golf ball, as a striking vibration / sound enhancement mechanism 200. This allows for efficient application of reaction force to the ball with minimal force, increasing distance. Surface vibration also improves the feel of the shot.

[0236] The surface vibrating member 15 has, for example, a net member 16 formed by weaving a string 19 in a net-like manner inside the frame 18 in the head-corresponding portion of the surface vibrating member 15, as shown in Figure 37, and a membrane member 17 that is attached from the striking surface 2 of the head 3 through the front surface of the hosel 4 to the front surface of the shaft 5. The head-corresponding portion (200A) of the membrane member 17 is provided to cover the front surface of the net member 16, and the hosel-corresponding portion (200B) and shaft-corresponding portion (200C) of the membrane member 17 extend from the head-corresponding portion (200A) of the membrane member 17 along the hosel 4 and shaft 5. The net member 16 has a structure similar to that of a tennis racket, for example. This allows for efficient application of reaction force to the ball. Preferably, the net member 16 and the membrane member 17 are individually detachable from the striking surface 2 of the head 3.

[0237] As the string 19 constituting the net member 16, it includes at least any one of natural fibers (gut (intestines of cows and sheep)), synthetic fibers (nylon fibers, polyester fibers), and elastic fibers (natural rubber fibers, synthetic rubber fibers). As the membrane member 17, it includes at least any one of a metal plate, a resin plate, a rubber membrane, and a leather membrane. Thus, by diverting existing strings (such as tennis strings and rubber belts), the net member can be realized at a low cost, and by diverting existing membrane products (such as the tympanic membrane and the rubber membrane of a table tennis racket), the membrane member can be realized at a low cost. Furthermore, the net member 16 and the membrane member 17 can be integrally formed into a structure similar to the hitting surface structure of a table tennis racket, or the skin of a drum can be stretched over a frame member as the net member 16.

[0238] Also, it is possible to make the insert made of metal. In this case, the insert may be formed in a lattice shape like the lid of a grating. Further, the net member 16 constituting the surface vibration member 15 (insert) may be formed of a net-shaped (mesh-shaped) net member (mesh member) using resin fibers such as fiber-reinforced plastic (FRP) and ultra-fine resin fibers. As a specific example of a mesh member using fiber-reinforced plastic or ultra-fine resin fibers, a mesh member in which strings made of fiber-reinforced plastic are woven into a flat net shape (mesh shape) can be cited. As another specific example, a mesh member in which ultra-fine resin fibers are three-dimensionally intertwined can be cited. In a golf club 1 having a surface vibration member (insert) using a mesh member, the vibration when hitting a golf ball tends to be amplified by the surface vibration member. Therefore, the hitting feeling can be improved.

[0239] In addition, the structure of the insert may be made similar to a gong structure. That is, the hitting surface 2 of the insert is made into a hanging structure, and when a golf ball hits this hitting surface 2 of the gong structure, a sound like that of a gong is produced. If a drumhead is stretched over the frame as the net component 16, or if the insert striking surface 2 is made of a gong structure, a vibration sensor that detects the vibration of the drumhead or the gong-structured insert can be installed, for example, inside the head of the golf club or integrated with or close to the insert. The vibration of the drumhead or the gong-structured insert can be amplified and output as sound through a speaker.

[0240] The surface vibration member 15 is detachably attached to the head 3. This allows it to be removed or attached according to the user's preference. The surface vibration member 15 can also be attached to existing golf clubs. In addition, a head cavity 7 may be provided by forming a hollow space inside the head 3, similar to the head cavity 7 described above. For example, as shown in Figures 36 and 38, a head cavity 7 may be formed inside the head body 14, with an opening provided on its side. The surface vibration member 15 (net member 16, membrane member 17) is attached so as to cover the opening in the head body 14. This allows the surface vibration of the surface vibration member 15 to resonate inside the head cavity 7, improving the feel of the shot.

[0241] Furthermore, an internal wire (auxiliary vibration transmission member) 30 may be installed inside the head cavity 7. The internal wire 30 is stretched inside the head cavity 7 and connected to the surface vibration member 15 via a connecting wire 40. This allows the surface vibration of the surface vibration member 15 to be transmitted through the shaft 5 and grip 6, as well as amplified as vibration of the internal vibrating wire 30, thereby improving the feel of the ball.

[0242] Furthermore, as shown in Figure 38, a shaft cavity 9 may be provided, similar to the shaft cavity 9 described above, by forming the inside of the shaft 5 into a hollow shape. With this configuration, surface vibrations can be reflected inside the shaft cavity 9, improving the feel of the ball. As shown in Figure 38, an internal shaft wire 20W may be provided inside the shaft cavity 9. The internal shaft wire 20W is stretched inside the shaft cavity 9 and connected to the internal head wire 30. With this configuration, the surface vibrations of the surface vibration member 15 can be transmitted through the hosel 4, shaft 5, and grip 6, and can also be amplified as vibrations of the internal shaft wire 20W, improving the feel of the ball.

[0243] Furthermore, as shown in Figure 39, a shaft-internal wire 20W may be stretched to connect the grip 6 and the head-internal wire 30. In other words, the upper end of the shaft-internal wire 20W may be fixed to the inside of the grip 6, so that the vibration of the surface vibration member 15 is transmitted not only through the shaft 5 and grip 6, but also as vibration of the shaft-internal wire 20W. With this configuration, vibration can be efficiently transmitted to the grip, further improving the feel of the shot.

[0244] When a golf club strikes a ball, if the golf ball hits the impact surface 2 of the insert, and the ball hits the sweet spot of the impact surface 2, a chime, gong, or buzzer may sound as an electronic sound, or an audio notification may be given. The tone of the chime, gong, or buzzer may also differ depending on whether the ball hits the sweet spot or not, or the audio may be changed. In this case, a sensor may be provided to detect whether the golf ball hits the sweet spot, or a sensor may be provided to detect whether the ball misses the sweet spot. Based on the detection information from this sensor (or these sensors), an amplifier may be used to output the sound of a chime, gong, or buzzer, or an audio notification, through a speaker.

[0245] Furthermore, a mechanism may be provided to detect the vibration of the surface vibrating member 15, electrically amplify it, and produce sound. A specific example of this mechanism is a structure in which the surface vibrating member 15 is formed in a net-like shape by weaving together string-like metal (magnetic) material, and a pickup coil placed close to the surface vibrating member 15 converts the vibration of the surface vibrating member 15 into an electrical signal, which is then amplified by an amplifier to produce sound.

[0246] Furthermore, as shown in Figure 39, the inner surface portion of the insert can be directly connected to the auxiliary vibration transmission member (internal head wire 30). In this way, vibrations from the insert are directly transmitted to the internal head wire 30, improving transmission efficiency and contributing to an improved feel when hitting the ball.

[0247] As shown in Figure 40(A), in a golf club 1 with a hosel, a net member 16 of a surface vibration member 15 (insert) may be provided extending from the striking surface 2 of the head 3 to the hosel 4 and shaft 5. In this case, a wider area for surface vibration can be secured, making it easier to further emphasize the vibration. Although not shown, a membrane member 17 may be provided to cover the entire surface of the net member 16.

[0248] As shown in Figure 40(B), in a golf club 1 with a hosel, a net member 16 of the surface vibration member 15 (insert) may be provided extending from the striking surface 2 of the head 3 to the hosel 4, shaft 5, and grip 6. Although not shown, a membrane member 17 may be provided to cover the entire surface of the net member 16. In this case, a wider area for surface vibration can be secured, and since the user directly touches the surface vibration member 15 with the grip 6, the vibration is more easily emphasized. In the golf club 1 of Figures 40(A) and (B), when the above gong structure is adopted, the head-corresponding portion of the surface vibration member 15, that is, the portion provided on the striking surface 2 of the head 3, has a gong structure (hanging structure).

[0249] Figures 40(A) and (B) show the golf club 1 and the surface vibration member 15 in disassembled form. In the golf club 1 shown in Figures 40(A) and (B), the shape of the hosel 4 is not limited to the illustrated shape, but can be freely applied to any well-known shape such as a straight neck, goose neck, crank neck, trapezoidal shape, or rectangular shape.

[0250] In the golf club 1 shown in Figures 40(A) and (B), the net member 16 forming the surface vibration member 15 (insert) may be made of a net-like (mesh-like) net member (mesh member) made of resin fibers such as fiber-reinforced plastic or ultrafine resin fibers. A specific example of a mesh member made of resin fibers such as fiber-reinforced plastic or ultrafine resin fibers is a mesh member made by weaving strings made of fiber-reinforced plastic into a flat net-like (mesh-like) structure. Another specific example is a mesh member made of a mat body in which ultrafine resin fibers are intertwined in a three-dimensional mesh structure. A surface vibration member 15 made of such a mesh member made of resin fibers tends to transmit vibrations easily. Therefore, the feel of the ball can be improved.

[0251] The golf club 1 shown in Figure 41(A) has a head 3, hosel 4, and shaft 5 formed from a frame 1F. The frame 1F consists of frame members that form the outlines of the head 3, hosel 4, and shaft 5. A vibrating plate member 200 is attached to the front-facing surface of the frame 1F, extending across the head 3, hosel 4, and shaft 5. Note that only a portion of the head 3, hosel 4, and shaft 5 may be formed from the frame. For example, the hosel 4 and shaft 5, excluding the head 3, may be formed from the frame.

[0252] The diaphragm member 200 may extend to the grip 6, which is not shown in the illustration. In the illustrated example, the frame 1F, consisting of two members, is shown as forming the hosel 4 and shaft 5, but the frame 1F forming the hosel 4 and shaft 5 may be composed of one member or two or more members.

[0253] The golf club 1 shown in Figure 41(B) has a hosel 4 and a shaft 5, respectively, formed from strip-shaped members 4G and 5G. Each strip-shaped member 4G and 5G is a plate member that extends in a strip shape in the axial direction of the golf club 1. A vibrating plate member 200 is attached to the head 3, hosel 4 (strip-shaped member 4G), and shaft 5 (strip-shaped member 5G). Note that only the head 3, hosel 4, or shaft 5 may be formed from strip-shaped members. Since the hosel 4 and shaft 5 are formed from strip-shaped members 4G and 5G, vibrations are easily transmitted. Note that the vibrating plate member 200 may extend to the grip 6, which is not shown.

[0254] The golf club 1 shown in Figure 41(C) has a widened section in the upper part of the shaft 5, which is wider in diameter than the rest of the shaft. This widened section functions as the grip 6. In other words, the golf club 1 shown in Figure 41(C) has a structure in which the shaft 5 and grip 6 are integrated. A vibrating plate member 200 is attached to this golf club 1, extending from the head 3, hosel 4, shaft 5, and grip 6. In this vibrating plate member 200, the part corresponding to the grip 6 is a widened section with a larger width dimension than the rest of the shaft.

[0255] Because the shaft 5 and grip 6 are integrated, vibrations are more easily transmitted to the grip 6 compared to a structure where the shaft 5 and grip 6 are separate. Also, because the upper part of the shaft 5 forms a widened section, the thickness of the gripping material (such as urethane) provided on the grip 6 can be reduced. As a result, vibrations are more easily transmitted to the user's hand.

[0256] The golf club 1 shown in Figure 41(C) has a widened section in the upper part of the shaft 5, which is wider in diameter than the rest of the shaft. This widened section functions as the grip 6. In other words, the golf club 1 shown in Figure 41(C) has a structure in which the shaft 5 and grip 6 are integrated. A vibrating plate member 200 is attached to this golf club 1, extending from the head 3, hosel 4, shaft 5, and grip 6. In this vibrating plate member 200, the part corresponding to the grip 6 is a widened section with a larger width dimension than the rest of the shaft.

[0257] The golf club 1 shown in Figure 41(D) is a modified version of the golf club 1 shown in Figure 41(B), in which the upper part of the shaft 5, which is made of a strip-shaped member 5F, forms a widened section with a larger diameter than the rest of the shaft. This widened section functions as a grip 6. A vibrating plate member 200 is attached to this golf club 1, extending across the head 3, hosel 4, shaft 5, and grip 6. In this vibrating plate member 200, the portion corresponding to the grip 6 forms a widened section with a larger width dimension than the rest of the shaft.

[0258] Although the diaphragm member 200 in Figures 41(A) to (D) is depicted as a flat plate, it is not limited to this shape and may be any shape, such as a cylindrical shape (tubular, rectangular) surrounding the head 3, hosel 4, shaft 5, and grip 6 (golf club 1). Also, the strip-shaped members 4W and 5W in Figures 41(B) and (D) above are not limited to flat plates and may be formed in a cylindrical shape such as a curved semi-cylindrical or rectangular tube.

[0259] In the golf club 1 of each of the embodiments and modifications described above, the shape of the grip 6 is not limited to the shape shown, and may be any shape. Furthermore, in the golf club 1, the shaft 5 and the grip 6 may be integrally formed. In this case, as shown in Figure 42(A), the diameters of the shaft 5 and the grip 6 may be set to be the same. Also, the golf club 1 shown in Figure 42(B) is similar to the golf club 1 shown in Figure 42(A), in which the diameters of the shaft 5 and the grip 6 are set to be the same, and the grip 6 is provided with a grip member 6G that covers the circumference of the grip 6. The grip member 6G is a gripping member that the user of the golf club 1 holds. Furthermore, as shown in Figure 42(C), the diameter of the grip portion 6 may be set to be larger than the diameter of the shaft 5. In this case, the grip 6 becomes easier to hold.

[0260] Furthermore, the material used for the grip member 6G is one that is soft and conforms to the user's hand. Specifically, this includes rubber (natural rubber), elastomer (resin material), fiber-reinforced plastic (FRP), ultrafine resin fibers, and metal. In Figure 42(B), the grip member 6G is clearly shown in comparison to Figure 42(A), but the grip 6 of the golf club 1 according to each of the embodiments and modifications described above may also be provided with the grip member 6G.

[0261] As a grip member 6G using resin fibers such as fiber-reinforced plastic (FRP) or ultrafine resin fibers, a net-like (mesh-like) net member (mesh member) made of resin fibers such as fiber-reinforced plastic or ultrafine resin fibers can be applied. A specific example of a mesh member using fiber-reinforced plastic or ultrafine resin fibers is a mesh member made by weaving strings made of fiber-reinforced plastic into a flat net-like (mesh-like) structure. Another specific example is a mesh member made by intertwining ultrafine resin fibers in a three-dimensional structure. A sheet-like cover may also be provided around the net member (mesh member). In a golf club 1 having a grip member 6G made of a mesh member, vibrations from the shaft 5 tend to be easily transmitted to the user's hand through the grip member 6G. Therefore, the feel of the shot can be improved.

[0262] Furthermore, the material used for grip 6 may be rubber (natural rubber), elastomer (resin material), fiber-reinforced plastic (FRP), ultrafine resin fibers, metal, etc. These materials are merely examples, and the materials used for grip 6 and grip component 6G are not limited to these. The materials used for each part of the golf club 1 (head 3, hosel 4, shaft 5, grip 6) may be any material, including various metals such as stainless steel, titanium, soft iron, bronze, aluminum, aluminum alloy, aluminum, and copper, as well as carbon, plastic, nanocellulose, carbon nanofiber, Japanese paper, leather, polyacetal, PET, glass, aluminum fiber, chemical fiber, resin, polypropylene, nanocellulose, and polyester.

[0263] A reinforcing member for strengthening the shaft 5 may be built into the detachable unit 70. In the detachable units 70 and 71 shown in Figure 42(D), a truss-structured reinforcing member 73 is built into the interior. Instead of the detachable units 70 and 71, reinforcing members to reinforce the strength of the shaft 5 may be built into the shaft cavity 9 of the shaft 5. In Figure 42(E), a truss-structured reinforcing member 74 is built into the shaft cavity 9 of the shaft 5.

[0264] Furthermore, the thickness (wall thickness) of the shaft 5 may be reduced to make it easier for vibrations to be transmitted through the shaft 5 to the user's hand gripping the grip 6. In this case, the shaft 5 itself can be said to function as a vibrating plate member. Alternatively, the shaft 5 may have both thick and thin sections, ensuring vibration transmission in the thin section and strength in the thick section.

[0265] In each embodiment and modification of the golf club 1, the axial dimension (length) of the hosel 4 is not limited. That is, the ratio of the hosel 4 to the shaft 5 is flexible. For example, the golf club 1 shown in Figure 43 has a larger ratio of the length of the hosel 4 to the length of the shaft 5 compared to the golf club 1 shown in Figure 1(A), etc. The vibrating plate member 200 is provided across the head 3, the hosel 4, and the shaft 5.

[0266] As a modification of the golf club 1 described above, the vibrating plate member 200 may extend to the head 3, hosel 4, shaft 5, and grip 6. In addition, Golf Club 1 may be equipped with the following functions: These functions may include an image system, vital data detection function, smartphone integration function, smartphone function, communication function, AI function, smart speaker function, display function, touch panel function, voice function (conversation function), GPS function, beacon function, etc.

[0267] Furthermore, if the head-compatible portion 200A of the vibrating plate member 200 is provided on the striking surface 2 of the head 3, the surface (face surface, striking surface) of the head-compatible portion 200A of the vibrating plate member 200 that strikes the golf ball may be milled (grooved).

[0268] Furthermore, if the head-compatible portion 200A of the vibrating plate member 200 is provided on the striking surface 2 of the head 3, the loft angle (degree of tilt of the club face) can be adjusted and changed by varying the thickness of the upper and lower portions of the head-compatible portion 200A of the vibrating plate member 200. The diaphragm member 200 may be painted with paint or coated. Any well-known type of paint may be used.

[0269] <Vibration sensor> In the modified version of the golf club 1 described above, various electrical devices, sensors, control devices (controllers), batteries, etc. may be incorporated. The golf club 1 described below with reference to Figures 44 to 48 is equipped with various electrical devices, sensors, control devices (controllers), batteries, etc., in addition to the vibrating plate member (impact vibration / impact sound enhancement mechanism) 200 provided across the head 3, hosel 4, and shaft 5.

[0270] Figure 44 is a perspective view of a modified golf club 1. The golf club 1 shown in Figure 44 has a vibrating plate member 200 that extends across the head 3, hosel 4, and shaft 5. In the figure, the golf club 1 and the vibrating plate member 200 are shown disassembled. As shown in Figure 44, in addition to the vibrating plate member 200 that extends across the head 3, hosel 4, and shaft 5, the golf club 1 has a vibration sensor 95 built into the hosel 4 to detect vibrations. The vibration sensor 95 may be attached to the outer surface of the hosel 4 or built into it. If a hosel cavity 8 is formed inside the hosel 4, the vibration sensor 95 may be placed inside it. By detecting vibrations with the vibration sensor 95, the magnitude and waveform of vibrations near the vibration source (hitting surface 2) can be objectively captured, further improving the feel of the shot. In addition, the magnitude and waveform of vibrations can be analyzed, and the effectiveness of golf practice can be enhanced by utilizing the analysis results. The information detected by the vibration sensor 95 may be transmitted to a computer (not shown) by means of wireless or wired connection, for example.

[0271] Furthermore, a vibration device 96 (actuator) that vibrates based on vibration information detected by the vibration sensor 95 may be built into the hosel 4. If a hosel cavity 8 is formed inside the hosel 4, the vibration device 96 may be placed inside it. The vibration device 96 may function, for example, to amplify and output the vibration detected by the vibration sensor 95. By amplifying the vibration with the vibration device 96, the vibration actually transmitted to the user can be increased, further improving the feel of hitting the ball.

[0272] Furthermore, a speaker 96A that emits sound based on vibration information detected by the vibration sensor 95 may be built into the hosel 4. If a hosel cavity 8 is formed inside the hosel 4, the speaker 96A including an amplifier may be placed inside it. The speaker 96A may function, for example, to amplify and output the vibration detected by the vibration sensor 95 as sound. As a result, when a golf ball is struck with one of the hitting surfaces of the golf club, the vibration at that time is detected by the vibration sensor 95 and can be heard as sound from the speaker 96A. At this time, the hollow hosel 4, shaft 5, and grip 6 function as a speaker box, amplifying and outputting the sound related to the vibration. As a result, the golf club 1 can function as a kind of electronic musical instrument.

[0273] Furthermore, as shown in Figure 44, the grip 6 may also have other vibration devices 97 (actuators) and a speaker 97A built into it. The vibration devices 97 and speaker 97A are, for example, located inside the grip cavity 10 within the grip 6. Similar to the vibration devices 96 and speaker 96A described above, the vibration devices 97 and speaker 97A function to amplify and output the vibrations detected by the vibration sensor 95 as they are, or to amplify and output the vibrations detected by the vibration sensor 95 as sound. By generating vibrations and emitting sound within the grip 6, the vibrations and sounds actually transmitted to the user can be amplified, further improving the feel of the shot.

[0274] <Transmitter> The golf club 1 shown in Figure 44 above may further include a transmitter 101 for transmitting information detected by the vibration sensor 95 to an external device. The transmitter 101 is built into, for example, the hosel 4. If a hosel cavity 8 is formed inside the hosel 4, the transmitter 101 may be placed inside it. The information detected by the vibration sensor 95 can be transmitted via the transmitter 101 to an external device, such as a computer (not shown), for example, by wireless or wired connection.

[0275] <Rhythm Box Function> The golf club 1 shown in Figure 44 above may be equipped with a controller 100 that has a rhythm box function for indicating the rhythm when the golf ball is launched and a synthesized voice generation function. The controller 100 is built into, for example, the hosel 4. If a hosel cavity 8 is formed inside the hosel 4, the controller 100 may be placed inside it. A speaker 96A is connected to the output side of the controller 100. Either the rhythm box function or the synthesized voice generation function of the controller 100 can output either the rhythm sound or the synthesized voice generated by the controller 100 from the speaker 96A when the golf ball is launched. The on / off switching of the rhythm box function and synthesized voice generation function of the controller 100, volume adjustment, and other various operations can be input from an indicator (not shown). The indicator may be built into the golf club 1. Alternatively, the indicator may be configured as an external device (e.g., a smartphone) connected by wireless connection. Furthermore, the various functions of the controller 100 may be configured as external devices (e.g., a smartphone) connected by wireless connection.

[0276] The golf club 1 shown in Figure 45 is a modified version of the golf club 1 shown in Figure 44, and an example configuration is given in which the vibration sensor 95', vibration device 96', and speaker 96A' are built into the shaft 5. That is, the vibration sensor 95, vibration device 96, speaker 96A, transmitter 101, and controller 100, which are built into the hosel 4, may also be built into the shaft 5.

[0277] The vibration sensor, vibration device, speaker, transmitter, and controller may be built into the shaft 5 in whole or in part. That is, the vibration sensor, vibration device, speaker, transmitter, and controller may be built into either the hosel 4 or the shaft 5, or into both. Alternatively, some of the vibration sensor, vibration device, speaker, transmitter, and controller may be built into one of the hosel 4 and the shaft 5, and the remaining parts may be built into the other of the hosel 4 and the shaft 5 (distributed, combined). Furthermore, all or some of the vibration sensor, vibration device, speaker, transmitter, and controller may be built into the grip 6.

[0278] Furthermore, each golf club 1 shown in Figures 44 and 45 may be equipped with a liquid crystal display 102 (display unit, electric display component) (display function). The liquid crystal display 102 is, for example, mounted on the upper side of the head 3 and connected to the output side of the controller 100. In this case, the liquid crystal display 102 can display vibration data detected by vibration sensors 95, 95' as numerical values, graphs, etc.

[0279] The liquid crystal display 102 may also display the launch direction of the golf ball. In this case, the controller 100 transmits an instruction signal to the liquid crystal display 102 to display the launch direction of the golf ball based on an instruction input from the indicator (see reference numeral 103 in Figure 46), thereby controlling the liquid crystal display 102 to display the launch direction of the golf ball. The indicator 103 (Figure 46) is an input means for inputting an instruction for the launch direction of the golf ball.

[0280] The display on the liquid crystal display 102 may be an arrow indicating the launch direction of the golf ball, or it may be a series of interconnected circles. In this case, the circles may become smaller towards the tip indicating the direction. This configuration improves the feel of the shot and also enhances convenience by allowing the launch direction of the golf ball to be freely displayed on the liquid crystal display 102. The indicator 103 and controller 100 can also be replaced with a smartphone. In this case, it is preferable to use a wireless connection between the controller 100 and the LCD display 102. Furthermore, the content of the instructions input to the indicator 103 may be input by, for example, the user of the golf club 1, an instructor (trainer), or an assistant (caddy).

[0281] Furthermore, regarding the display function described above, one or more impact sensors 104 (see Figure 46) can be provided in the head 3. When a golf ball hits the striking surface 2, the impact data is detected by the impact sensors 104 and collected by the controller 100. This impact data can then be displayed on the liquid crystal display 102 as numerical data, graphs, or other formats.

[0282] For example, if both the rhythm box function and the display function are included, the two functions can be switched using a toggle switch SW, as shown in Figure 46. In this case, if the switch SW is switched to connect to the liquid crystal display 102, the launch direction and digitized and graphed impact data will be displayed on the liquid crystal display 102. If the switch SW is switched to connect to speakers 96A and 96A', either the rhythm sound or synthesized voice generated by either the rhythm box function or the synthesized voice generation function of the controller 100 will be output from speakers 96A and 96A'.

[0283] When the switch SW is used to connect to both the LCD display 102 and speakers 96A and 96A', the LCD display 102 displays the launch direction and digitized and graphed impact data, while speakers 96A and 96A' output either a rhythm sound or synthesized voice.

[0284] In addition, in each golf club 1 shown in Figures 44 and 45, the mounting positions of the vibration sensor 95, vibration device 96, speaker 96A, transmitter 101, controller 100, vibration sensor 95', vibration device 96', speaker 96A', liquid crystal display 102, vibration device 97, and speaker 97A are not limited to the illustrated examples and may be at any position on the golf club 1.

[0285] <Adapter> Figures 47(A) and (B) are side views illustrating yet another modification of the golf club 1 described above. Figures 47(A) and (B) show a golf club 1 having a crank-shaped hosel 4 as shown in Figure 1(A), but the shape of the hosel 4 is not limited to this. The golf club 1 shown in Figures 47(A) and (B) has a vibrating plate member (not shown) provided across the head 3, hosel 4, and shaft 5, as well as adapters 3A and 3B described below.

[0286] One of several adapters 3A and 3B is detachably attached to the underside of the head 3 of the golf club 1. Multiple types of these adapters 3A and 3B are available, differing, for example, in shape, mass, center of gravity, etc. For example, adapter 3A shown in Figure 47(B) is used when it is desired to increase the lie angle L compared to adapter 3B shown in Figure 47(A).

[0287] Adapters 3A and 3B are intended to be attached to the underside of the head 3 by, for example, the user or instructor (trainer) of the golf club 1, by selecting one of them. Adapters 3A and 3B are preferably attached to the underside of the head 3 via an easily detachable locking structure (clip) or fastening structure (screw). By using adapters 3A and 3B that are suitable for the user of the golf club 1's physique and swing form, it becomes easier to optimize the swing trajectory of the golf club 1, thereby improving the effectiveness of practice.

[0288] The lie angle L refers to the angle that the shaft 5 makes with respect to the horizontal plane when the striking surface 2 of the head 3 is viewed horizontally from the front, and is the angle that is closer to the user than the shaft 5. Furthermore, the examples in Figures 47(A) and (B) can be applied to any of the golf clubs 1 described above, and in that case, it goes without saying that the configuration other than the adapters 3A and 3B and their mounting method will be the same as those in each embodiment.

[0289] <Weight component> Figures 48(A) and (B) are perspective views illustrating modified heads 3. The golf club 1 shown in Figures 48(A) and (B) has a vibrating plate member (not shown) extending across the head 3, hosel 4, and shaft 5, as well as a weight member 61 described below. As shown in Figures 48(A) and (B), the head 3 may have a weight member 61 built in to change the center of gravity of the head 3. In this case, the center of gravity can be changed by making the mounting state (position and angle) of the weight member 61 adjustable. The mounting state of the weight member 61 may be manually adjustable by the user, or a weight motor 62 (drive source) may be provided to move the weight member 61.

[0290] Figure 48(A) is a perspective view showing the head 3 with two sets of weight members 61 and a weight motor 62 built into its upper surface. The weight members 61 are made of a material with a different density than the material that makes up the head 3, and are installed inside hollow cylindrical recesses formed in the upper surface of the head 3. The weight motor 62 changes the position of each weight member 61 by rotating them along the inner circumferential surface of the recess. With this configuration, the position of the weight members 61 can be easily changed to shift the center of gravity of the head 3, providing a good feel when hitting the ball.

[0291] Figure 48(B) is a perspective view showing a head 3 with weight members 61 provided inside a linear recess formed in the upper surface of the head 3. The weight motor 62 changes the position of each weight member 61 by sliding it along the inner circumferential surface of the recess. Even with this configuration, the position of the weight members 61 can be easily changed to shift the center of gravity of the head 3, providing a good feel when hitting the ball.

[0292] The movement of the weight member 61 described above may be controlled using the user's smartphone. Figure 48(C) is a processing block diagram illustrating a processing configuration for controlling the movement of the weight member 61 using the user's smartphone. The weight motor 62 is connected to the motor control unit 63 so as to be able to send and receive data. The motor control unit 63 is a computer device (control unit) for controlling the weight motor 62 in order for the weight motor 62 to move the weight member 61.

[0293] The motor control unit 63 is wirelessly connected to the smartphone 65 via the communication unit 64, enabling data communication. The smartphone 65 is a portable terminal used by the user to instruct the movement of the weight member 61, and it exchanges control signals with the motor control unit 63 of the golf club 1. The smartphone 65 is equipped with a touch-input display 65A.

[0294] The display 65A functions as an input unit for inputting instructions to move the weight member 61 to a desired position, and also functions as a display unit for monitoring and displaying the position of the weight member 61 after it has been moved in response to the instructions. The wireless connection between the smartphone 65 and the motor control unit 63 may be based on a well-known wireless communication standard such as Bluetooth®.

[0295] An example of controlling the movement of a weight member 61 using a smartphone 65 is described below. First, a connection is established between the smartphone 65 and the motor control unit 63. After establishing the connection, the motor control unit 63 controls the weight motor 62 to move the weight member 61 to a predetermined initial position and supplies the smartphone 65 with information about the current position of the weight member 61.

[0296] After moving the weight member 61 to a predetermined initial position, the user can input instructions to move the weight member 61 from their smartphone 65. When a movement command is input from the smartphone 65, the motor control unit 63 controls the weight motor 62, which moves the weight member 61.

[0297] The smartphone 65 can monitor the display 65A with an image showing the position of the weight member 61 after it has moved in response to a movement instruction, based on the current position information of the weight member 61 supplied from the motor control unit 63. The user can check the current position of the weight member 61 and instruct the weight member 61 to move using the display 65A of the smartphone 65.

[0298] When a user inputs a movement instruction from their smartphone 65 to move the weight member 61 to a desired position, the smartphone 65 transmits an instruction signal to the motor control unit 63. Based on the instruction signal, the motor control unit 63 controls the weight motor 62 to move the weight member 61. When the weight member 61 moves, the position information of the weight member 61 is supplied to the smartphone 65 via the motor control unit 63, and the current position of the weight member 61 is updated on the smartphone 65's display 65A. In this case, the position of the weight member 61 can be easily and visually adjusted using the smartphone 65.
