Description

[Technical field]

[0001] The present invention relates to a golf club for hitting a golf ball, a mounting unit, a golf practice system using the golf club, an insert for a golf club, and a portable mobile terminal. [Background technology]

[0002] Conventionally, there are known golf clubs such as woods, irons, hybrids, utilities, and putters in which a shaft with a grip is connected to a head by a hosel. The hosel is removably fixed to, for example, the shaft or head. This structure makes it easy to replace the shaft or head (see Patent Documents 1 and 2). Further, golf clubs that do not have a hosel, that is, golf clubs in which a shaft with a grip is connected to a head, have also been generally known. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-058337 [Patent Document 2] JP 2014-036894 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the case of a golf club with a hosel, the vibration generated in the head when hitting a golf ball is transmitted to the palm of the user (golfer) holding the grip via the shaft, and is recognized as part of the hitting feel of the golf club. On the other hand, the hosel interposed between the shaft and the head can act to inhibit the transmission of such vibration. Therefore, a golf club with a hosel has a problem in that it is difficult to obtain a good hitting feel compared to a golf club without a hosel. The hitting feel means the feeling or shot feeling that the user has when hitting a golf ball. A general hitting feel includes not only physical vibrations but also sensory comfort (feeling) of the operation, such as a feeling of hitting, a sense of moderation, and a sense of accomplishment. Furthermore, even with golf clubs that do not have a hosel, it is difficult to obtain a good hitting feel unless some kind of ingenuity is used.

[0005] One of the objectives of the present invention was invented in light of the above-mentioned problems, and is to provide a golf club, a detachable unit, a golf practice system, a golf club insert, and a portable mobile terminal that are capable of improving the hitting feel. In addition to this objective, another objective of the present invention is to achieve an effect derived from each configuration shown in the "Description of the Invention" described later, which is an effect that cannot be obtained by conventional techniques.

[0016] [I. Description of the First Embodiment] [1.Basic structure] 1(A) to (C) are perspective views illustrating a golf club 1 (putter) according to a first embodiment. The golf club 1 includes a head 3, a shaft 5, and a grip 6. A striking surface 2 (face) for striking a golf ball is provided on the side of the head 3. The shaft 5 is formed in an axial shape (long, thin rod shape), and one end (the lower end in FIG. 1) of the shaft 5 is connected to the head 3. The cross-sectional shape of the shaft 5 may be circular, elliptical, or polygonal. A grip 6, which is the part held by the user, is provided at the other end (the upper end in FIG. 1) of the shaft 5. Like the shaft 5, the cross-sectional shape of the grip 6 may be circular, elliptical, or polygonal. The shape of the head 3 is shown as a pin type in FIG. 1 as an example, but is not particularly limited thereto, and may be any well-known shape such as a mallet type, a neo-mallet type, or the like in addition to the pin type.

[0017] A diaphragm member 200 is attached to the head 3 as a first impact vibration / impact sound emphasizing mechanism that emphasizes and transmits to the user the impact vibration or impact sound generated when the golf ball is struck on the striking surface. The golf club 1 in FIG. 1(A) has a straight shaft 5, whereas the golf club 1 in FIG. 1(B) has a crank-shaped shaft 5 having a bent portion at the lower end of the shaft 5 that is bent toward the front of the head 3 (the side where the striking surface 2 is located). The golf club 1 in FIG. 1(C) is such that the shaft 5 and the head 3 are connected by a hosel 4 having a bent portion that is bent toward the front of the head 3 (the side where the striking surface 2 is located). The hosel 4 is a joint member that connects the lower end (one end) of the shaft 5 and 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 may 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 a structure in which a straight shaft 5 is connected to the head 3 as shown in Figures 1(A) to (C), a structure in which a crank-shaped shaft 5 is connected to the head 3, or a structure in which the shaft 5 is connected to the head 3 via a crank-shaped hosel 4.

[0018] <Flat diaphragm member> The diaphragm member 200 is a plate member for emphasizing impact vibrations that occur when a golf ball is struck, and its thickness, rigidity, shape, material, etc. are set to emphasize the impact vibrations. The diaphragm member 200 is an example of a planar vibration member formed in a plane that vibrates in a plane upon impact with a golf ball. In other words, it can be said that the golf club 1 has the diaphragm member 200 as a planar vibration member. The diaphragm member 200 in the golf club 1 of Figs. 1(A) to (C) is formed of a thin flat plate that extends in a plane direction parallel to the striking surface 2. The diaphragm member 200 may be attached integrally with the head 3 in a non-replaceable (non-detachable) state, or may be attached detachably (post-installable, separate) to the head 3. The diaphragm member 200 may be attached non-detachably or detachably to the head 3 by any conventionally known method such as adhesion, crimping, welding, or fitting.

[0019] FIG. 2(A) is a side view of the head 3 of the golf club 1 in FIG. 1(A) as viewed from the direction of arrow A, with the left side in the figure being the surface (front) of the head 3 on which the striking surface 2 is formed. 2(A) is attached to the head 3, and is attached to the front side on which the striking surface 2 is formed. The diaphragm member 200 is formed in a shape that covers a part or the whole of the head 3. In other words, the diaphragm member 200 functions as the striking surface 2. According to this golf club 1, the impact vibration generated when hitting a golf ball is transmitted to the diaphragm member 200 (first impact vibration / impact sound emphasizing mechanism) and emphasized by the diaphragm member 200 (first impact vibration / impact sound emphasizing mechanism). Therefore, it is possible to emphasize (intensify) the vibration transmitted to the palm of the user through the shaft 5 and the grip 6, and the impact sound (sound) heard by the user. Therefore, it is possible to improve the hitting feel and impact sound compared to existing golf clubs that do not have the diaphragm member 200 attached.

[0020] Figures 2(B) and (C) are modified examples of Figure 2(A). In Figure 2(B), a diaphragm member 200 is attached to the back side of the head 3, which is opposite to the front side. 2(C) shows a head 3 having a sub-diaphragm member 201 in addition to the diaphragm member 200 attached to the front side of the head 3. The sub-diaphragm member 201 is attached to the back side of the head 3 opposite the front side. The sub-diaphragm member 201 is a plate member having the same function as the diaphragm member 200 of emphasizing impact vibrations generated when a golf ball is hit, and is provided as a plate member separate from the diaphragm member 200. In these cases, the impact vibration generated when hitting the golf ball is transmitted to the vibrating plate member 200 (first impact vibration / impact sound emphasis mechanism) and emphasized by the vibrating plate member 200 (first impact vibration / impact sound emphasis mechanism), thereby emphasizing the vibration transmitted to the user's palm and the impact sound (sound) heard by the user, thereby improving the feel and sound of the impact.

[0021] <Hollow section of the head and diaphragm material> The golf club 1 shown in FIGS. 3(A) to (C) is a modified example of the golf club 1 shown in FIGS. 2(A) to (C), and has a head 3 having a hollow head portion 202 (indicated by a dashed line in the drawings). The golf club 1 in Fig. 3(A) has an opening 202A on the front side of the head 3 that communicates with the head hollow section 202 and the outside, and a vibration plate member 200 is attached to cover the opening 202A. The golf club 1 in Fig. 3(B) has an opening 202A on the back side of the head 3 that communicates with the head hollow section 202 and the outside, and a vibration plate member 200 is attached to cover the opening 202A. The golf club 1 in Fig. 3(C) has openings 202A, 202A' on both the front and back sides of the head 3 that communicate with the head hollow section 202 and the outside, and a vibration plate member 200 and a sub-vibration plate member 201 are attached to cover the openings 202A, 202A'. The head 3 in FIG. 3(C) can be said to have a drum-shaped structure in which both sides (openings 202A, 202A′) of the cavity of the head hollow portion 202 are covered with the diaphragm member 200 and the sub-diaphragm member 201.

[0022] In the golf club 1 of Figures 3(A) to (C), the hollow head portion 202 forms a resonance mechanism that emphasizes the impact sound generated when hitting a golf ball and transmits it to the outside from the opening 202A (and 202A'). That is, the golf club 1 of Figures 3(A) to (C) has the hollow head portion 202 that forms a resonance mechanism as a first impact vibration / impact sound emphasizing mechanism. Therefore, by emphasizing the impact sound generated when hitting a golf ball with the hollow head portion 202, it is possible to improve the impact sound (acoustic) heard by the user. Furthermore, since the diaphragm member 200 (and the sub-diaphragm member 201) is attached to the opening 202A (and 202A'), the hitting feel and hitting sound can be further improved. 3(A) to 3(C), the head hollow section 202 forming the resonance mechanism may have a structure that does not have the opening 202A (and 202A'). Also, in FIG. 3(A) to 3(C), the structure may have a structure that does not have the diaphragm member 200 (and the sub-diaphragm member 201). The impact sound resonates in the head hollow section 202, so that the impact sound can be emphasized. In this case, at least the side of the striking surface 2 may be closed without providing the opening 202A.

[0023] <Vibration plate component with hosel> 4(A) to (C) are perspective views of a golf club 1 having a hosel 4. The golf club 1 shown in Fig. 4(A) to (C) has the hosel 4 and is configured similarly to the golf club 1 in Fig. 1, except that a vibration plate member 200 is attached to the hosel 4 as a second impact vibration / impact sound emphasizing mechanism. 4(A) to (C) is formed in a rectangular flat plate shape having a certain thickness, extending in a plane direction parallel to the striking surface 2, and the hosel 4 and the head 3 are provided so as to be flush (form the same plane) with the striking surface 2. A vibration plate member 200 is provided on this hosel 4. The shape of the hosel 4 is not limited to the example shown in the drawings, and may be any well-known shape. In the golf club 1 in Fig. 4(A), a straight-extending shaft 5 is connected to a hosel 4, whereas in the golf club 1 in Fig. 4(B), a crank-shaped shaft 5 having a bent portion at the lower end of the shaft 5 that is bent toward the front of the head 3 is connected to the hosel 4. The hosel 4 of the golf club 1 in Fig. 4(C) is extended from the upper end of a flat plate-shaped portion connected to the head 3, and having a bent portion at the upper end of the flat plate-shaped portion that is connected to the head 3, toward the front of the head 3. Regarding the connection structure between the hosel 4 and the shaft 5 of the golf club 1, any well-known structure may be applied, such as a structure in which a straight shaft 5 is connected to the hosel 4 as shown in Figures 4(A) to (C), a structure in which a crank-shaped shaft 5 is connected to the hosel 4, or a structure in which a crank-shaped hosel is further extended from the hosel 4.

[0024] FIG. 5(A) is a side view of the head 3 and hosel of the golf club 1 in FIG. 4(A) as viewed from the direction of arrow B, with the left side in the figure being the front side of the head 3. FIG. 5(A) is attached to the front side of the hosel 4. The diaphragm member 200 is formed in a shape that covers a part or the whole of the hosel 4. The diaphragm member 200 may be formed separately from the hosel 4, or may be formed integrally with the hosel 4. In this case, the impact vibration generated when hitting the golf ball is transmitted from the head 3 to the diaphragm member 200 attached to the hosel 4 and is emphasized by the diaphragm member 200 (second impact vibration / impact sound emphasis mechanism). Therefore, it is possible to emphasize (increase) the vibration transmitted to the palm of the user through the shaft 5 and the grip 6 and the impact sound (sound) heard by the user. Therefore, it is possible to improve the hitting feel and impact sound compared to existing golf clubs that do not have the diaphragm member 200 attached.

[0025] Figures 5(B), (C), and (D) are modified examples of Figure 5(A). In Figure 5(B), the diaphragm member 200 is attached to the back side of the hosel 4. Also, the golf club 1 in Figure 5(C) has a sub-diaphragm member 201 attached to the back side of the hosel 4 in addition to the diaphragm member 200 attached to the front side of the hosel 4. The diaphragm member 200 in Figure 5(D) is attached midway between the front and back of the hosel 4. In these cases, too, the impact vibrations generated when hitting the golf ball are transmitted from the head 3 to the vibration plate member 200 attached to the hosel 4 and emphasized by the vibration plate member 200, thereby emphasizing the vibrations transmitted to the user's palm and the impact sound (acoustic sound) heard by the user, thereby improving the feel and sound of the impact. In addition, in a golf club 1 having a hosel 4 as shown in Figures 5(A) to (D), in addition to or instead of the vibration plate member 200 (sub-vibration plate member 201) attached to the hosel 4, a vibration plate member 200 (sub-vibration plate member 201) may be attached to the head 3 as shown in Figures 2(A) to (C).

[0026] The golf club 1 shown in FIGS. 6(A) to (D) has a hosel 4 and a vibrating plate member 200 (third impact vibration / impact sound emphasizing mechanism) attached to both the head 3 and the hosel 4. The diaphragm member 200 in Fig. 6(A) is formed of a single plate-like member extending across the front sides of both the head 3 and the hosel 4. The golf club 1 in Fig. 6(B) is obtained by attaching a sub-diaphragm member 201 to the back side of the hosel 4 in addition to the diaphragm member 200, as compared to the golf club 1 in Fig. 6(A).

[0027] <Bending shape of diaphragm material> 6(C)-(D), the diaphragm member 200 attached to both the head 3 and the hosel 4 is bent in a crank shape (S-shape) when viewed from the side. Specifically, the diaphragm member 200 in FIG. 6(C) is connected to a portion attached to the rear side of the head 3 and a portion attached to the front side of the hosel 4 via a bent portion. The diaphragm member 200 in FIG. 6(D) is connected to a portion attached to the front side of the head 3 and a portion attached to the rear side of the hosel 4 via a bent portion. The diaphragm member 200 in FIG. 6(D) is connected to a portion attached to the front side of the head 3 and a portion attached to the rear side of the hosel 4 via a bent portion.

[0028] 6(A) to (D), the impact vibrations generated when hitting a golf ball are transmitted from the head 3 to the diaphragm member 200 (third impact vibration / impact sound emphasizing mechanism) attached to the hosel 4 and emphasized by the diaphragm member 200 (third impact vibration / impact sound emphasizing mechanism), thereby emphasizing the vibrations transmitted to the palm of the user and the impact sound (acoustic sound) heard by the user, thereby improving the feel and sound of the impact. In each of FIGS. 6(C) and 6(D), the diaphragm member 200 may have rounded corners at the bent portions.

[0029] <Hosel hollow section and diaphragm material> FIG. 7(A) shows a modified example of FIG. 6(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. 7(A), the diaphragm member 200 is attached so as to cover the opening 202A of the head hollow portion 202 and the opening 203A on the front side of the hosel hollow portion 203. The sub-diaphragm member 201 is attached so as to cover the opening 203A on the back side of the hosel hollow portion 203.

[0030] Fig. 7(B) is a modified example of Fig. 7(A). In Fig. 7(A), the head hollow portion 202 and the hosel hollow portion 203 are formed separately and do not communicate with each other. In contrast, in Fig. 7(B), the head hollow portion 202 and the hosel hollow portion 203 communicate with each other. In the golf club 1 of Figures 7(A) and (B), the impact sound (acoustic sound) heard by the user can be improved by emphasizing the impact sound generated when hitting a golf ball using the head hollow portion 202 and hosel hollow portion 203 which form a resonance mechanism, and further, the hitting feel and impact sound can be further improved by the diaphragm member 200 (and sub-diaphragm member 201) attached to the openings 202A, 203A (and 203A').

[0031] The golf club 1 in Figures 7(A) and (B) has been given as an example having a vibration plate member 200 and a sub-vibration plate member 201 as in Figure 6(B), but in any of the golf clubs 1 in Figures 6(A) to (D), it is possible to improve the feel and sound of the impact by providing a head hollow portion 202 and a hosel hollow portion 203 that form a resonance mechanism and openings 202A, 203A (and 203A') as in Figures 7(A) and (B).

[0032] <Modifications of the hosel shape> The golf club 1 in FIGS. 8(A) to (F) has a hosel 4 with a different shape from that of the golf club 1 in FIG. 4(A). The golf club 1 in FIG. 8(A) has a hosel 4 that is trapezoidal (or substantially triangular) when viewed from the front, and a diaphragm member 200 is attached to the trapezoidal hosel 4. The golf club 1 in FIG. 8(B) has a semicircular hosel 4 that is semicircular (or arc-shaped) when viewed from the front, and a diaphragm member 200 is attached to the semicircular hosel 4. The golf club 1 in Figure 8(C) has a vibration plate member 200 attached to a trapezoidal hosel 4, and differs from that in Figure 8(A) in that the front surface of the hosel 4 is located behind the front surface (striking surface 2) of the head 3 (it is not flush).

[0033] Even if the hosel 4 of each golf club 1 has the shape shown in Figures 8(A) to (C), the diaphragm member 200 (and the sub-diaphragm member 201) can be attached in the manner shown in Figures 5(A) to (C) and Figures 6(A) to (D). Figures 8(A) to (C) are merely examples, and the hosel 4 may have any shape, size, or thickness. In other words, regardless of the shape, size, and thickness of the hosel 4, by attaching the diaphragm member 200 (and the sub-diaphragm member 201), it is possible to improve the hitting feel and hitting sound. 8(D) to 8(E), a crank-shaped shaft 5 bent forward of the head 3 is connected to the golf club 1. The structure connecting each hosel 4 and the shaft 5 may be any well-known structure.

[0034] <Providing a vibration plate member instead of a hosel> 9(A) to (D) show modified examples of a diaphragm member 200 attached to the head 3 of a golf club 1 (see FIG. 1) that does not have a hosel 4. The diaphragm members 200 in FIGS. 9(A) to (D) are all made of a plate member extending parallel to the striking surface 2, have a portion extending above the head 3, and are connected to the shaft 5 via a connecting portion 204 located on the upper edge. In other words, it can be said that the structures in FIGS. 9(A) to (D) are such that the head 3 and the shaft 5 are connected via the diaphragm member 200 instead of the hosel 4.

[0035] Specifically, the diaphragm member 200 in FIG. 9(A) is provided upright on the upper surface of the head 3 and is provided flush with the striking surface 2 of the head 3. The golf club 1 in Figure 9(B) has, in addition to the vibration plate member 200 in Figure 9(A), a sub-vibration plate member 201 erected on the upper surface of the head 3, and this sub-vibration plate member 201 is arranged on the rear side of the head 3 relative to the vibration plate member 200. Diaphragm member 200 in FIG. 9(C) differs from golf club 1 in FIG. 9(B) in that its lower end extends to the lower end of head 3 and is superimposed (attached) to striking surface 2 of head 3. The golf club 1 in FIGS. 9(B) and (C) can be said to have a drum-like structure in which the diaphragm member 200 and the sub-diaphragm member 201 are disposed facing each other with a space between them. 9(D) differs from the golf club 1 in FIG. 9(A) in that the lower end of the diaphragm member 200 in FIG. 9(D) extends to the lower end of the head 3 and is superimposed on the striking surface 2 of the head 3.

[0036] <Modifications of the diaphragm member> The golf club 1 shown in Figures 10(A) to (D) is a modified example of Figures 9(A) to (C). While the vibration plate member 200 in Figures 9(A) to (C) is formed of a plate member extending parallel to the striking surface 2, the vibration plate member 200 in Figures 10(A) to (D) is formed in a curved plate shape that is curved in a vertical cross section perpendicular to the striking surface 2. The dimensions, curvature, etc. of the curved portion can be appropriately set so as to emphasize the striking vibration and striking sound.

[0037] 10(A) and (B) is disposed on the upper surface of the head 3 in the same manner as in FIG. 9(A), but differs from FIG. 9(A) in that it is formed in a curved plate shape. This diaphragm member 200 may be integral with the head 3 or may be separate from the head 3.

[0038] The diaphragm member 200 in Fig. 10(A) is formed into a curved plate shape that is convex toward the back side in a vertical cross section perpendicular to the striking surface 2. The diaphragm member 200 in Fig. 10(B) is formed into a curved plate shape that is convex toward the front side in a vertical cross section perpendicular to the striking surface 2.

[0039] The vibration plate member 200 in Figures 10(C) and (D) is a modified example of Figure 9(C), and differs from Figure 9(C) in that the portion of the vibration plate member 200 extending from the lower end of the head 3 to the connecting portion 204 above the upper surface of the head 3 is formed into a curved plate shape. The diaphragm member 200 in Fig. 10(C) is formed into a curved plate shape in which the portion above the top surface of the head 3 is convex toward the rear side in a vertical cross section perpendicular to the striking surface 2. The diaphragm member 200 in Fig. 10(D) is formed into a curved plate shape in which the portion above the top surface of the head 3 is convex toward the front side in a vertical cross section perpendicular to the striking surface 2.

[0040] 11(A) to (E) extends from the lower end of the head 3 to the connecting portion 204, and has a bent portion bent in a crank shape (or S shape). The direction of the bent portion and the shape of the diaphragm member 200 can be freely set according to the combination with the shape of the head 3.

[0041] <Head and hosel frame structure> 12(A) and (B) are views of the golf club 1 seen from the front, showing the head 3 (and the hosel 4) in cross section. The golf club 1 in FIG. 12(A) is a golf club without a hosel, and the head 3 has a frame structure 3F that surrounds the peripheral portion of the diaphragm member 200. The frame structure 3F is a frame body that surrounds the four sides (periphery) of the rectangular diaphragm member 200. In this case, the diaphragm member 200 supported by the frame structure 3F emphasizes the impact vibration and impact sound generated when hitting a golf ball, thereby improving the hitting feel and impact sound. In addition, since the head 3 is formed of a frame body, it is easy to achieve weight reduction. <Plastic Models> In addition, this golf club 1 can be configured as an assembly-type golf club (in other words, a ``plastic model'' type golf club in which parts are combined) in which the user freely selects and assembles various parts such as the diaphragm member 200, face (striking surface), weight, balance, insert, hosel, and sub-diaphragm member 201 to the frame structure 3F.

[0042] The golf club 1 in Fig. 12(B) has frame structures 3F and 4F in which the head 3 and the hosel 4 surround the peripheral portion of the diaphragm member 200. The frame structures 3F and 4F in Fig. 12(B) are integrally formed. The golf club 1 illustrated in Figures 13(A) and (B) has a trapezoidal (or substantially triangular) hosel 4 when viewed from the front. In the golf club 1 in Figure 13(A), the hosel 4 has a frame structure 4F, and in the golf club 1 in Figure 13(B), both the head 3 and the hosel 4 have frame structures 3F and 4F. The golf clubs 1 illustrated in Figures 14(A) and (B) have a semicircular hosel 4. In the golf club 1 in Figure 14(A), the hosel 4 has a frame structure 4F, and in the golf club 1 in Figure 14(B), both the head 3 and the hosel 4 have frame structures 3F and 4F. 14(C) is a golf club 1 having a structure in which a diaphragm member 200 having an upper portion with a semicircular contour is supported by a frame structure 3F. In this case, the upper portion of the diaphragm member 200 extends upward beyond the frame structure 3F, and a shaft 5 is connected to the upper portion of the diaphragm member 200. The golf club 1 illustrated in FIG. 14(D) is a modified example of a structure in which a diaphragm member 200 having a semicircular contour at the top is supported by a frame structure 3F, and the periphery of the diaphragm member 200 is surrounded by the frame structure 3F. The golf clubs 1 in any of Figs. 12(B), 13(A) and (B) and Figs. 14(A) to (D) have the same effects as those in Fig. 12(A).

[0043] Fig. 15(A) shows a golf club 1 in which a head 3 having a frame structure 3F is integrally formed with a shaft 5 in a state where it cannot be replaced. Fig. 15(B) shows a golf club 1 in which a head 3 having frame structures 3F, 4F and a hosel 4 are integrally formed with a shaft 5 in a state where it cannot be replaced. In this case, the same effect as in Fig. 12(A) is achieved.

[0044] 16(A) to (D) show examples of golf clubs 1 in which the diaphragm member 200 is formed in a truncated cone shape. Each of the diaphragm members 200 in Figs. 16(A) to (D) is attached with the large diameter side of the truncated cone shape facing the back side of the head 3. The golf club 1 in Fig. 16(A) does not have a hosel 4, and a vibration plate member 200 is attached to the back side of the head 3. The golf club 1 in Fig. 16(B) has a hosel 4, and a vibration plate member 200 is attached to the back side of the hosel 4. In this case, the impact sound can be particularly emphasized in the direction in which the larger diameter side of the truncated cone shaped diaphragm member 200 faces (the rear side of the head 3).

[0045] The golf club 1 in Fig. 16(C) differs from the golf club 1 in Fig. 16(A) in that an enclosure 200E is provided to surround the periphery of the diaphragm member 200. Fig. 16(D) shows two diaphragm members 200, 200' arranged coaxially. According to the structures of FIGS. 16(C) and (D), the impact sound can be further emphasized.

[0046] The diaphragm member 200 in Fig. 16(E) is formed in a dome shape. The golf club 1 in Fig. 16(E) does not have a hosel 4, and the dome-shaped diaphragm member 200 is attached to the back side of the head 3. The diaphragm member 200 is attached in a position that forms a convex shape toward the back side of the head 3. In this case, the impact sound can be particularly emphasized in the direction in which the convexity of the dome-shaped diaphragm member 200 faces (the back side of the head 3). The diaphragm member 200 in Fig. 16(F) is a combination of a truncated cone-shaped diaphragm member and a dome-shaped diaphragm member. That is, the diaphragm member 200 has a dome portion (indicated by a dashed line in the figure) and a cone portion extending from the periphery of the dome portion in a truncated cone shape. The diaphragm member 200 in Fig. 16(F) is attached to the back side of the head 3 with the large diameter side of the cone portion and the protrusion of the dome portion 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.

[0047] <Diaphragm material for curved speaker type> 17(A) to (H) are explanatory diagrams of a diaphragm member 200 formed in a curved bent plate shape. Each diaphragm member 200 is curved in an arc shape, and emphasizes the impact vibration and impact sound by the vibration of the arc-shaped curved surface. It is well known that the vibration-based sound can be improved (volume and audibility improved) by utilizing the vibration of such a curved surface. The golf clubs 1 in Figures 17(A)-(C) and (G) have an L-shaped head 3 when viewed from the side and do not have a hosel. The golf clubs 1 in Figures 17(D) and (E) have a U-shaped head 3 when viewed from the side and do not have a hosel 4, and Figure 17(F) has an L-shaped head 3 and hosel 4 when viewed from the side, and the head 3 and hosel 4 are assembled to form a U-shape when viewed from the side.

[0048] The diaphragm member 200 in Fig. 17(A) to (C) is attached in a position extending toward the back side of the head 3, and is formed in a bent plate shape curved upward or downward in a vertical cross section perpendicular to the striking surface 2 (a surface when the head 3 is viewed from the side). The diaphragm member 200 in Fig. 17(A) and (C) is curved upward in a vertical cross section perpendicular to the striking surface 2. The diaphragm member 200 in Fig. 17(B) is curved downward in a vertical cross section perpendicular to the striking surface 2.

[0049] The golf club 1 in Fig. 17(D) and (E) is an example of a configuration in which two curved plate-like vibration plate members 200, 200' are provided on the back side of the head 3, and the golf club 1 in Fig. 17(F) is an example of a configuration in which two curved plate-like vibration plate members 200, 200' are provided on the back side of the head 3. Each vibration plate member 200, 200' is attached in a position extending toward the back side of the head 3, and is formed in a curved plate shape curved upward or downward in a vertical cross section perpendicular to the striking surface 2. The golf club 1 in Fig. 17(H) is configured in common with the golf club 1 in Fig. 17(F) except that each vibration plate member 200, 200' is attached to the head 3 which is U-shaped in side view. The combination of the posture, dimensions, curvature, etc. of each diaphragm member 200, 200' can be freely set without being limited to the examples shown in Figs. 17(D) to (F) and (H).

[0050] The diaphragm member in Fig. 17(G) is a combination of the truncated cone-shaped diaphragm member 200 shown in Fig. 16(A) and the curved plate-shaped diaphragm member 200'. By combining two different types of diaphragm members, the impact sound can be further improved. 18(A) to (C) show modified examples regarding the bending direction of the curved plate-shaped diaphragm member 200. Fig. 18 is a plan view of the head 3 as seen from above, with the left side of the page being the front side (front). The plate-shaped diaphragm member 200 in Fig. 18(A)-(C) is a diaphragm member 200 having a bent plate shape curved in one (or the other) direction of the width in the horizontal plane when the head 3 is viewed from above. The head 3 in Fig. 18(A) and (B) has two bent plate-shaped diaphragm members 200, 200'. The plate-shaped diaphragm member in Fig. 18(C) is a combination of the truncated cone-shaped diaphragm member 200 illustrated in Fig. 16(A) and the above-mentioned bent plate-shaped diaphragm member 200'. In Fig. 18(B), the plate-shaped diaphragm members 200, 200' may be integrally formed.

[0051] <Modification of curved plate-shaped diaphragm member> 19(A) to 19(E) are plan views of the head 3 showing modified examples of the diaphragm member 200, with the left side of the paper being the front side (front). 19(A) to (C) show a modified example of the curved plate-like diaphragm member 200, in which an arc-shaped diaphragm member 200 that is convex toward the rear side of the head 3 in the horizontal plane when the head 3 is viewed from above is attached to the rear side of the head 3. In Fig. 19(A), the diaphragm member 200 is attached to the rear side of the head 3, and a rib 200R is provided between the diaphragm member 200 and the rear side of the head 3 in a direction that intersects with the arc. The rib 200R reinforces the diaphragm member 200 and improves vibration transmission.

[0052] Fig. 19(B) shows an example in which a diaphragm member 200 is attached in a recess 3X recessed in the upper surface of the head 3. Fig. 19(C) shows that the recess 3X to which the diaphragm member 200 is attached in Fig. 19(B) is covered with a lid 3Y.

[0053] FIG. 19(D) shows an arc-shaped diaphragm member 200 that is concave toward the rear side of the head 3 in a horizontal plane when the head 3 is viewed from above, attached to the rear side of the head 3. In FIG. 19(D), a rib 200R is attached to the curved surface of the diaphragm member 200, extending along an arc. One or more ribs 200R may be attached. The multiple ribs 200R are arranged, for example, in parallel in the vertical direction. That is, the number of the multiple ribs 200R may be one or more. FIG. 19(E) shows a mallet-shaped head 3 having a sole portion 3W extending toward the flat surface side, and a diaphragm member 200 is attached to the upper surface of the sole portion 3W.

[0054] <Horn type resonance structure; Dome type resonance structure> 20(A) to (D) show the golf club 1 according to the second embodiment, with the head 3 shown in a cross-sectional side view. 20(A), the head 3 and the hosel 4 have a hollow portion 202 in which a horn-shaped conduit 206 is formed, 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 (horn-type resonance mechanism, phonograph-type resonance mechanism) that emphasizes the impact sound generated in the conduit 206 when the golf ball is struck and transmits it to the outside from the opening 206A. The golf club 1 in FIG. 20(B) is provided with a horn-shaped conduit 206 and an opening 206A communicating with the conduit 206 in the head 3. As shown in FIG. The pipe 206 has an R-shape with a larger diameter toward the opening 206A, and has excellent acoustic characteristics, so that the impact sound can be further improved.

[0055] 20(C), the head 3 and the hosel 4 have a dome-shaped (spherical) conduit 206 formed in the hollow portion 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 emphasizes the impact sound generated when a golf ball is struck in the conduit 206 and transmits it to the outside from the opening 206A. The golf club 1 in FIG. 20(D) is provided with a horn-shaped conduit 206 and an opening 206A communicating with the conduit 206 in the head 3. As shown in FIG. In this case, the impact sound can be improved by resonating the impact sound through the dome-shaped duct 206.

[0056] The shape of the diaphragm member 200 may be a cylinder as shown in FIG. 21(A). Also, as shown in FIG. 21(B), the diaphragm member 200 may be disposed so that a plate-like member extends horizontally from the rear side of the head 3. The diaphragm member 200 may be attached to the head 3 by bending an end of the diaphragm member 200 into an L-shape and fixing the L-shaped bent portion to the rear side of the head 3. In addition to the above, the diaphragm member 200 may be attached to the head 3 by, for example, inserting an end of the diaphragm member 200 into the rear side of the head 3 or welding an end of the diaphragm member 200 to the rear side of the head 3. Fig. 21C is a view seen from above of Fig. 21(B). As shown in Fig. 21(C), on the rear side of the head 3, a plurality of diaphragm members 200 of different lengths are arranged side by side in the width direction of the head 3. That is, the number of diaphragm members 200 is one or more. In the cases of Figs. 21(B) and (C), the structure vibrates the diaphragm member 200 supported in a cantilevered manner on the rear side of the head 3, and sound can be generated by the vibration of the diaphragm member 200, like the musical instrument marimba.

[0057] 22(A) to 22(C), a spoiler 200S can be provided between the diaphragm member 200 and the head 3. The spoiler 200S is detachable from the golf club 1 and can be attached later. In other words, the spoiler 200S can be attached later to an existing golf club to improve the impact vibration and impact sound. 23(A)-(D) are examples of the shape of the diaphragm member 200, and are views of the diaphragm member 200 seen from the side. A weight can be attached to the diaphragm member 200 to adjust the center of gravity, or a blade can be detachably attached to the diaphragm member 200. The shapes of the diaphragm member 200 in FIG. 23(A)-(D) are examples of shapes that can improve the impact vibration and impact sound. Examples of shapes that can improve the impact vibration and impact sound include a C-shape (steel drum type) as shown in FIG. 23(A), a V-shape as shown in FIG. 23(B), a shape combining a V-shape and a plate piece extending horizontally as shown in FIG. 23(C), and a C-shape with a sole part (lower surface part) extending horizontally backward of the head 3 as shown in FIG. 23(D). In addition, for example, as shown in FIG. 23(B), a detachable weight or blade member 200X may be attached to the end of the diaphragm member 200. The member 200X can adjust the center of gravity of the golf club 1. The member 200X can set a center of gravity on the back side of the head 3 (double balance) in addition to the original center of gravity of the golf club 1. This makes it easier to hit the ball through the follow-through.

[0058] <Integration of diaphragm material and shaft / hosel> 24(A) to (E) show a diaphragm member 200 that is integrally formed with the shaft 5 / hosel 4 in a non-replaceable state. By integrating the diaphragm member 200 with the shaft 5, impact vibrations that occur when hitting a golf ball can be directly transmitted to the shaft 5. In FIG. 24(A), the vibration plate member 200 integrated with the shaft 5 is detachably attached to the head 3 formed in a frame shape. The vibration plate member 200 is disposed on the frame-shaped head 3 with gaps on both the left and right sides, and both gaps are closed by the plate member 200Y. Since the vibration plate member 200 is provided at a distance from the head 3, the impact vibration generated when hitting the golf ball can be efficiently guided to the shaft 5 without dispersing it to the head 3. Note that, as shown in FIG. 31(B) described later, the vibration plate member 200 may be provided on the frame-shaped head 3 without gaps on both the left and right sides. Note that the plate member 200Y may be a vibration plate member. That is, a vibration plate member made of a different material from the vibration plate member 200 integrated with the shaft 5 is disposed in place of the plate member 200Y. In this case, different types of vibration plate members can be combined.

[0059] 24(B) shows a diaphragm member 200 integrated with a shaft 5 that is detachably attached to a head 3 formed in a frame shape, and both the left and right sides of the upper surface of the diaphragm member 200 are closed with cover members 200Z. Also, a front cover member 200K that covers the entire surface of the head 3 on the front side of the head 3 may be detachably attached to the diaphragm member 200 so as to overlap it from the front. 24(C) shows a diaphragm member 200 integrated with the shaft 5 formed in a circular shape. In the case of a circular shape, the mounting angle relative to the head 3 can be made adjustable. In this case, a locking mechanism is provided to fix the mounting angle relative to the head 3 at the adjusted angle after the angle is adjusted. 24(D) has a diaphragm member 200 integrated with a hosel 4. In this case, a shaft 5 is connected to the hosel 4 integrated with the diaphragm member 200. 24(A)-(D), the diaphragm member 200 is integrated with the shaft 5 and / or hosel 4, and is configured to be detachably attached to the separate head 3, so that the diaphragm member 200 can be freely combined with the head 3. The diaphragm member 200 can be freely attached and detached to the head 3, just like replacing a cartridge (cassette tape). In other words, this golf club 1 can be configured as an assembly-type golf club in which a user freely selects and assembles various parts such as the diaphragm member 200, face (striking surface), weight, balance, insert, hosel, and sub-diaphragm member 201 for the head 3. Furthermore, the golf club 1 in Figures 24(A) to (D) is not limited to a straight shaft, and may have a structure in which the vibration plate member 200 is integrated with the crank-shaped hosel 4 / shaft 5 as shown in Figures 1(B), (C), 4(B), and (C). An insert may be disposed on the front surface of the diaphragm member 200, or an insert may be built into the diaphragm member 200. The diaphragm member 200 may be formed integrally with the insert, or the insert may be detachably attached. The shape of the diaphragm member 200 is not limited to the example shown in the figure and can be freely selected.

[0060] <Vibration transmission rib; fan rib> 25(A) and (B) show a golf club 1 according to a third embodiment, which is provided with a vibration transmitting rib 210 as an impact vibration / impact sound emphasis mechanism (first impact vibration / impact sound emphasis mechanism, second impact vibration / impact sound emphasis mechanism, or third impact vibration / impact sound emphasis mechanism). 25(A) and (B), the vibration transmission rib 210 extends in a rib shape from the head 3 to the shaft 5, and transmits impact vibrations generated when hitting a golf ball from the head 3 to the shaft 5. The vibration transmission rib 210 is a ridge-like protruding portion extending from the head 3 to the front surface of the shaft 5, and is formed so as to emphasize the impact vibrations. The golf club 1 in Fig. 25(A) is a golf club 1 having a hosel 4 and provided with a vibration transmitting rib 210. The golf club 1 in Fig. 25(B) is a golf club 1 not having a hosel 4 and provided with a vibration transmitting rib 210. In detail, the vibration transmission rib 210 has a plurality of branches 21A attached to the head 3 (and the hosel 4), and a trunk 210B extending along the axial direction of the shaft 5 and connected to the branches 210A at the lower end side of the shaft (to imagine, it is shaped like the ribs of a fan). By providing the vibration transmitting rib 210, it is possible to increase the impact vibration transmitted to the palm of the user, thereby improving the hitting feel.

[0061] Other modified examples are shown in Figs. 26(A) to (E) and 27. 26(A) shows a structure in which an opening 202A on the upper surface side of a head hollow portion 202 in a bowl-shaped (bell-shaped) head 3 is blocked by a diaphragm member 200. In this case, the impact sound generated when a golf ball is struck with the striking surface 2 of the head 3 resonates within the head hollow portion 202 and is emitted to the outside from the opening 202A, and the impact vibration is emphasized by the diaphragm member 200. It is not necessary to provide the diaphragm member 200 that closes the opening 202A. Even in this case, the effect of emphasizing the impact sound in the head hollow portion 202 can be obtained.

[0062] Fig. 26(B) shows a configuration in which a fin 5X is provided between the shaft 5 and the head 3. The fin 5X is provided as a thin plate-like or film-like vibration plate member, and the impact vibration can be emphasized by the fin 5X. The fin 5X may be detachably attached to the golf club 1 (head 3). In this case, the fin 5X can be attached to an existing golf club to emphasize the impact vibration. The golf club 1 in Figure 26 (C) has, as an impact vibration / impact sound emphasis mechanism (first impact vibration / impact sound emphasis mechanism), a sound collector 220 attached to the rear side of the head 3 for collecting the impact sound, an impact sound propagation tube 221 for propagating the impact sound collected by the sound collector 220, and an earphone section 222 for transmitting the impact sound propagated through the impact sound propagation tube 221 to the user. In this case, the user can clearly hear the impact sound collected by sound collector 220 from earphone unit 222. Note that a wireless structure may be used in which impact sound propagation tube 221 is not provided, sound collector 220 and earphone unit 222 are wirelessly connected, and the impact sound collected by sound collector 220 is transmitted to earphone unit 222 by wireless communication. The sound collector 220, the impact sound propagation 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 propagation tube 221, and the earphone unit 222 can be freely attached to an existing golf club.

[0063] The golf club 1 in Fig. 26(D) has, as an impact vibration / impact sound emphasis mechanism (first impact vibration / impact sound emphasis mechanism, or second impact vibration / impact sound emphasis mechanism, or third impact vibration / impact sound emphasis mechanism), a pickup 230 that detects impact vibration and converts it into an electric signal, an amplifier unit 231 that amplifies the impact sound based on the electric signal detected by the pickup 230, and a speaker 232 that outputs the amplified impact sound. The amplifier unit 231 and the speaker 232 configure a "speaker unit." The pickup 230 (dashed line in the figure), the amplifier unit 231 (dashed line in the figure), and the speaker 232 are attached to the back side of the head 3. In this case, the impact vibration is converted into an electric signal and the impact sound can be electrically amplified and output from the speaker unit, so that the impact sound can be output more clearly.

[0064] Fig. 26(E) is a modification of Fig. 26(D), in which a pickup 230 (dashed line in the figure), an amplifier section 231 (dashed line in the figure), and a speaker 232 (dashed line in the figure) are provided in the head hollow section 202 of the head 3. The pickup 230, the amplifier section 231, and the speaker 232 may be detachably attached to the golf club 1 (head 3). In this case, the pickup 230, the amplifier section 231, and the speaker 232 can be freely attached to an existing golf club. The head 3 shown in Fig. 26(F) has a front side having a striking surface 2 formed from a thin plate, and by making the plate thickness on the striking surface 2 side thinner, striking vibration is emphasized. As shown in Fig. 26(F), by removably mounting batteries 3E on both sides of the head 3 and wiring power lines from the batteries 3E appropriately, it is possible to add various electrical functions to the head 3. Examples of electrical functions that can be added to the head 3 include LED lights, electrical decorations, lasers, sensors, testers, and communication functions.

[0065] 27(A) and (B) are explanatory diagrams of a golf club 1 having a vibration emphasizing member attached to the shaft 5, and are radial cross-sectional views of the shaft 5. The vibration emphasizing member is a member that emphasizes and transmits to the user the impact vibrations that occur when a golf ball is struck against the striking surface 2, and is provided on the circumferential surface around the axis of the shaft 5, extending in the axial direction of the shaft 5. 27(A), a vibration emphasizing member 5A is provided on the inner peripheral surface of a hollow shaft 5. The vibration emphasizing member 5A is formed, for example, of a coating film formed by plating the inner peripheral surface of the shaft 5 with, for example, rhodium, copper, gold, or the like. When carbon fiber is used as the vibration emphasizing member 5A, for example, a plurality of carbon fibers extending along the axial direction of the shaft 5 can be bundled together and formed into a shape that fits along the inner peripheral surface or the outer peripheral surface of the shaft 5. 27(B), a vibration emphasizing member 5B is provided on the outer circumferential surface of the hollow shaft 5. The vibration emphasizing member 5B is formed, for example, of a coating film formed by plating the outer circumferential surface of the shaft 5 with, for example, rhodium, copper, gold, or the like. When using carbon fiber as the vibration emphasizing member 5B, for example, a plurality of carbon fibers extending along the axial direction of the shaft 5 can be bundled together and formed into a shape that fits along the inner or outer circumferential surface of the shaft 5. 27(A) and (B) may be made of any material that enhances impact vibration, and may be made of, for example, various metals such as rhodium, copper, alloys, and pure gold, or carbon fiber. When carbon fiber is used, for example, a plurality of carbon fibers extending along the axial direction of the shaft 5 may be bundled together and formed into a shape that fits the inner or outer circumferential surface of the shaft 5. 28 has a vibration sensor 300 in which an impact vibration / impact sound emphasis mechanism (first impact vibration / impact sound emphasis mechanism) is attached to the head 3 and detects vibrations occurring on the impact surface 2, and an actuator 301 that vibrates based on an electrical signal output from the vibration sensor 300, and transmits the vibration of the actuator 301 to the user via the vibration transmission member 20. In this case, since the vibration generated by the electrical drive is transmitted to the user in addition to the actual impact vibration, the impact vibration can be emphasized.

[0066] Additionally, the above-described embodiments are merely examples, and the embodiments can be freely combined. Furthermore, the shape of the golf club 1 (the shape, size, thickness, etc. of the head 3, hosel 4, and shaft 5) is not limited to the above-described embodiment, and may be any well-known shape. For example, the attachment position of the shaft 5 to the head 3 (or the hosel 4) is not limited to that shown in the figure. Specifically, the position of the shaft 5 in the front-to-rear direction of the head 3 may be anywhere, such as a position on the front side of the head 3, a position on the rear side, or a position intermediate between the front and rear sides. The position of the shaft 5 in the width direction of the head 3 may be anywhere, such as one end side, near the center, the other end, a position on the rear side, or a position intermediate between the front and rear sides.

[0067] For example, as shown in FIG. 29(A), a golf club 1 having a hosel 4 and a head 3 may be provided with a pickup 230, an amplifier section 231, and a speaker 232 attached to the back side of the hosel 4. Also, as shown in FIG. 29(B), in a golf club 1 having a hosel 4 and a head 3, a hosel hollow portion 203 of the hosel 4 and a head hollow portion 202 of the head 3 are provided in communication with each other, and a speaker 232 can be attached in the hosel hollow portion 203 so that the hosel hollow portion 203 functions as a speaker box and the impact sound output by the speaker 232 is emitted from an opening 203A. 26(D) and (E), an electronic sound may be output from an electronic sound source based on an electrical signal detected by the pickup 230. The tone of the electronic sound may be, for example, the tone of an electronic drum. That is, an electronic drum may be attached to the golf club 1. In addition, a radio, a smartphone, etc. can be detachably attached to the golf club 1.

[0068] <Plastic model style> The golf club 1 can be configured as an assembly-type golf club in which a user freely selects and assembles various parts such as the diaphragm member 200, striking surface (face), weight, balance, insert, hosel, and sub-diaphragm member 201 with respect to the head 3, in other words, as a plastic model-type golf club. Here, the insert may be formed integrally with the diaphragm member 200, for example, or may be a separate body from the diaphragm member 200. The head 3 and the striking surface may be formed integrally with the diaphragm member 200, or may be separate bodies. The striking surface may be formed integrally with the diaphragm member 200, or may be a separate body. For example, the golf club 1 in Figures 30(A) and (B) has weights 3Z ​​removably attached to the back side of the frame-shaped head 3. The golf club 1 in Figure 30(A) has weights 3Z ​​removably attached to both sides of the back side of the head 3. The golf club 1 in Figure 30(B) has weights 3Z ​​removably attached to the back side of the head 3, extending rearward in a planar shape from the back side. The size, shape, and number of weights 3Z ​​are not limited to those described above and may be any. When the diaphragm member 200 is provided, the number of the diaphragm members 200 may be one or more. When a plurality of diaphragm members 200 is provided, the diaphragm members 200 of various shapes can be freely combined.

[0069] 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. 31(A) to (F) show modified examples of a structure in which a diaphragm member 200 and a shaft 5 are integrated. The golf club 1 in FIG. 31(A) is different from the golf club 1 in FIG. 24(B) above in that a cover member 200Z is not provided and the upper edge of the diaphragm member 200 is formed on the same plane as the upper surface of the head 3, but the rest is the same. The golf club 1 in FIG. 31(B) is different from the golf club 1 in FIG. 24(A) above in that a plate member 200Y is not provided and the diaphragm member 200 is provided without a gap in the width direction relative to the frame-shaped head 3, but the rest is the same. The golf club 1 in Fig. 31(C) has a structure in which a diaphragm member 200 integrated with a shaft 5 is attached to a hosel 4. The golf club 1 in Fig. 31(D) has a structure in which a diaphragm member 200 integrated with a shaft 5 is attached to both the head 3 and the hosel 4. The golf club 1 in Figures 31(D) and (E) has a structure in which a diaphragm member 200, the contour of whose upper part is semicircular when viewed from the front, is integrated with a shaft 5 and attached to a head 3. In the golf club 1 in Figure 31(D), the upper part of the diaphragm member 200 protrudes upward beyond the upper part of the head 3. In the golf club 1 in Figure 31(E), the upper part of the diaphragm member 200 does not protrude beyond the upper part of the head 3, and the periphery (upper, lower and both sides) of the diaphragm member 200 is surrounded by the frame-shaped head 3. In this way, the diaphragm member 200 may have any shape (such as a contour or a thickness). The diaphragm member 200 may be any type, such as a thin plate having a small thickness, a plate having a relatively large thickness, or a film-like member having an extremely small thickness. Furthermore, the various modifications described above may be combined as appropriate.

[0070] The material used for the diaphragm member 200 is not particularly limited. As the material, a substance capable of emphasizing the impact vibration / impact sound may be appropriately selected. Examples include various metals such as steel, alloy, pure gold, rhodium, copper, pottery, ceramic, plastic, urethane, synthetic resin such as synthetic rubber, natural rubber (natural resin, rubber), wood, natural fiber (gut (cow, sheep intestines)), synthetic fiber (nylon fiber, polyester fiber), leather, Japanese paper, polyacetal, PET, glass, aluminum fiber, chemical fiber, resin, polypropylene, aluminum, copper, nanocellulose, paper, polyester, etc. Also, the diaphragm member 200 may be coated so as to emphasize the impact vibration / impact sound. The diaphragm member 200 is not limited to being made of one material, but can be made of a combination of a plurality of materials including the various materials exemplified above. Furthermore, the diaphragm member 200 is not limited to being formed from a single plate-like member, but can be formed into a planar (membrane-like) shape by combining (weaving) rod- or string-like members, for example.

[0071] The golf club 1 in Fig. 32(A) is a modified example of the structure in which the circular diaphragm member 200 shown in Fig. 24(C) is integrally formed with the shaft 5, and differs from the golf club 1 in Fig. 24(C) in that the diaphragm member 200 is attached to the hosel 4. In this case, the attachment angle of the diaphragm member 200 to the hosel 4 can be adjusted. After adjusting the attachment angle of the diaphragm member 200 to the hosel 4, a fixing mechanism (locking mechanism) that fixes it at that angle can be provided.

[0072] Figure 32(B) is a modified example of Figure 31(A), and is the same as the previous example, except that head 3 has a wall surface blocking the front side as striking surface 2, and diaphragm member 200 is attached to the back side of striking surface 2. In this case, diaphragm member 200 can be attached to and detached from head 3 by inserting it from above head 3 (like changing a cassette tape). The golf club 1 in Fig. 32(C) differs from that in Fig. 32(B) above in that the diaphragm member 200 is built into the head 3. As a modification of the golf club 1 in Fig. 32(C), the connection portion between the diaphragm member 200 and the shaft 5 may be built into the head 3, and the diaphragm member 200 may be exposed on the front side as a striking surface.

[0073] 33(A) and (B) show modified examples of the ones shown in FIGS. 20(B) and (D), and have a structure in which a horn-shaped or dome-shaped conduit 206 is hollowed out in the head 3. FIG.

[0074] Furthermore, the head 3, hosel 4, and shaft 5 may have any known shape and can be freely combined. For example, the golf club 1 according to the above-mentioned various embodiments and modifications is not limited to the one in which the head 3 is connected to the straight shaft 5 shown in Figures 1(A) and 4(A), but can be applied to the one in which the head 3 is connected to the crank-shaped shaft 5 shown in Figures 1(B) and 4(B), or the one in which the shaft 5 is connected to the head 3 via the crank-shaped hosel 4 shown in Figures 1(C) and 4(C). The bending direction of the crank-shaped shaft 5 or hosel 4 is not limited to bending toward the front side as illustrated in Figures 1(B), (C), and 4(B) and (C), but may be bending toward one side in the width direction, for example, as shown in Figures 34(A), (B), 35(A), and (B).

[0075] 36(A) and (B) are cross-sectional views of a golf club 1 having hollows formed inside the head 3, hosel 4, and shaft 5. Here, the hosel 4 has a hosel cavity 8 formed therein. Similarly, the shaft 5 has a shaft cavity 9 (shaft hollow portion) formed therein, and the head 3 has a head cavity 7 formed therein. The head cavity 7 and the shaft cavity 9 each communicate with the hosel cavity 8.

[0076] By providing a cavity inside the head 3, hosel 4, shaft 5, grip 6, etc., the vibration of the striking surface 2 is converted into the vibration of the air inside the cavity. This allows the vibration of the striking surface 2 to be transmitted to the user not only as a physical vibration but also as sound. In other words, the user can confirm the vibration of the striking surface as sound, and the hitting feeling can be improved. Also, as shown by the dashed line in FIG. 36(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, or a shaft opening 13 may be formed that connects the internal space of the shaft 5 to the outside. This makes it possible to increase the sound that reaches the user's ears, and further improve the hitting feeling. The openings 11 to 13 may be located on the side where the striking surface 2 is formed (front side), on the opposite side (back side), or on the side. The hosel cavity 8, head cavity 7, and shaft cavity 9 communicating with the openings 11 to 13 may be configured as a resonance chamber (resonance mechanism) that emphasizes the impact sound generated in the cavities 7, 8, and 9 when hitting a golf ball and transmits it to the outside through the openings 11, 12, and 13. In this way, the sound reaching the user's ears can be made louder, further improving the hitting feel.

[0077] In the modified examples of Figs. 36(A) and (B), only one of the openings 11 to 13 may be provided, or the openings 11 to 13 may not be provided (the openings 11 to 13 may not be provided). Also, instead of all of the head 3, the hosel 4, and the shaft 5, one or more of the head 3, the hosel 4, and the shaft 5 may be selectively provided with a hollow interior. For example, the interior of the hosel 4 may be hollow and the interiors of the head 3 and the shaft 5 may be solid, the interior of the head 3 may be hollow and the interiors of the hosel 4 and the shaft 5 may be solid, or the interior of the shaft 5 may be hollow and the interiors of the head 3 and the hosel 4 may be solid. Alternatively, the interiors of the head 3 and the shaft 5 may be hollow and the interior of the hosel 4 may be solid, the interiors of the hosel 4 and the shaft 5 may be hollow and the interior of the head 3 may be solid, or the interiors of the head 3 and the hosel 4 may be hollow and the interior of the shaft 5 may be solid.

[0078] <Golf practice system> [1. System configuration] Next, a golf practice system to which the above-mentioned golf club 1 is applied will be described. In the golf practice system described below, as an example, a golf club 1 having a "vibration plate member" is applied as an impact vibration / impact sound emphasis mechanism (first impact vibration / impact sound emphasis mechanism, second impact vibration / impact sound emphasis mechanism, or third impact vibration / impact sound emphasis mechanism). However, any of the above-mentioned various golf clubs 1 may be applied to this golf practice system. In other words, the impact vibration / impact sound emphasis mechanism provided in the golf club 1 applied to this golf practice system is not limited to a "vibration plate member" and may be any of the above-mentioned types of impact vibration / impact sound emphasis mechanisms. It is to be noted that the system can also be applied to a golf club having a fourth impact vibration / impact sound emphasis mechanism and a vibration plate member described below. FIG. 37 is an explanatory diagram showing the overall configuration of a golf training system S. This golf training system S includes a golf training machine T for putting practice. As is well known, putting in golf is a shot made by using a golf club (typically a "putter") to hit a golf ball into a hole called a cup. The golf training machine T can be used not only for putting practice using a putter, but also for swing practice using golf clubs other than putters, such as drivers and irons.

[0079] The practice machine T is provided with a cup area T1 in which a cup C is provided on the golf ball rolling surface, and a hitting area T2 which is provided apart from the cup C, has a golf ball rolling surface, and is a hitting position for a user. The practice machine T is, for example, a practice green, and in this case, the cup C is recessed into the golf ball rolling surface of the cup area T1. As another example, the practice machine T is a golf practice mat. In this case, in the case of a golf practice mat, the cup C is not recessed, but is provided as a predetermined area (flat surface) on the golf ball rolling surface. In addition, in the case of a golf practice mat, the cup C may be formed as a shallow recessed portion on the mat. In other words, the cup C is not limited to a hole, and may be any target position for cupping in a golf ball. In the following description, the case where the cup C is a hole recessed into the golf ball rolling surface will be described. The training machine T is a facility for a user (golfer) standing in a hitting area T2 to practice putting by hitting a ball B toward a cup C provided in a cup area T1 with a golf club 1. 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.

[0080] In this embodiment, the directions used in the explanation of the golf practice system S are defined as follows. Taking the user putting in the hitting area T2 as a reference, the direction from the user toward the cup C is "front" (marked "F" in the figure), and the opposite side of "front" is "back" (marked "B" in the figure), and "left" and "right" (marked "L" and "R" in the figure) are defined based on "front". In addition, "up" and "down" (marked "U" and "D" in the figure) are defined based on the direction in which gravity acts.

[0081] As shown in Fig. 37, a cup C provided in a cup area T1 of a training machine T is disposed in front of a 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 cup C to a user in the hitting area T2.

[0082] The golf practice system S in Figure 37 is provided with 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 photography unit 600 arranged in the hitting area T2.

[0083] In addition to these units 250, 500, 600, and 700, the system S also includes a control unit 350 that manages the system S, and a terminal device 400 owned by a user. The devices 250, 350, 400 to 700 in the system S are connected to each other via a wireless communication network so that they can transmit and receive data, and can operate in cooperation with each other. The wireless communication network is a network that complies with well-known wireless communication standards such as Wi-Fi and Bluetooth (registered trademark).

[0084] The outline of this system S is that the control unit 350 generates guide information for providing guidance to the user's golf play based on monitor information acquired by the units 250, 500, 600 and 700, the control unit 350 transmits the guide information to the terminal device 400 etc., and the terminal device 400 etc. provides guidance based on the guide information in advance (in advance) before the user hits the ball, for example. That is, in this system S, the devices 250, 350, 400 to 700 work together via a network to provide interactive guidance to the user's golf practice. The guide is advice to the user regarding golf play, model plays, etc. Specifically, the advice and model plays include the hitting form, swing rhythm of the golf club, the ball's hitting direction, timing, etc.

[0085] The monitor information acquired by the units 250, 500, 600, and 700 in the system S is the measurement result regarding the user's golf play. The monitor information includes a plurality of video data, cup-in information, ball hitting information, hitting vibration / sound information accompanying hitting the ball, golf club head angle, etc. The cup unit 250 , the pin unit 500 , the club unit 700 and the photographing unit 600 are monitor information sources that provide monitor information to the control unit 350 .

[0086] <Cup unit> The cup unit 250 is built into (attached to) the cup C, and is a mechanism provided for providing monitor information in the cup C to the control unit 350. The cup unit 250 includes a first control device (referred to as the "control device" in the figure) 251, a first sensor (first detection means, referred to as the "sensor" in the figure) 252, and a first communication device (first transmitting device, referred to as the "communication device" in the figure) 253. The first control device 251 is an electrical control device including a processor for controlling the cup unit 250, a storage device, and the like.

[0087] A first sensor 252 and a first communication device 253 are connected to the first control device 251 so as to be capable of transmitting and receiving data. The first sensor 252 is a detection means provided for detecting cup-in information indicating that the golf ball B has been cupped into the cup C. As the first sensor 252, for example, an impact sensor that detects the impact of the golf ball B falling into the cup C is used.

[0088] First communication device 253 is a wireless communication device connected to control unit 350 (external) via a wireless communication network. Cup unit 250 can transmit a detection signal (cup-in information) of first sensor 252 to control unit 350 (external) and receive information from the external via first communication device 253.

[0089] In addition, the cup unit 250 includes additional devices such as a camera 255 for photographing the surroundings of the cup C, an audio device 256 including an amplifier, a speaker, and a microphone, a lighting device 257, a laser irradiator 258, and a power source (not shown) for supplying power. These devices 251 to 258 and various devices not shown may be provided detachably with respect to the cup unit 250 or integrally with the cup unit 250.

This increases the amount and type of information taken into account when generating guide information, making it possible to provide the user with a higher quality guide.

[0106] The transmitting device 353 transmits the guide information generated by the control device 351 to the terminal device 400 . In addition, the transmitting device 353 may transmit guide information to at least one of the cup unit 250, the pin unit 500, the club unit 700 and the photographing unit 600 (i.e., any device within the system S) in addition to or instead of the terminal device 400. Various functions of the control unit 350, including the guide information generation process in the control device 351, may be provided by cloud computing using computing services on a cloud environment (Internet environment).

[0108] The display 402 is an example of a display device that displays (presents) a guide based on guide information to a user by some visual image such as a moving image or a still image. An example of the display 402 is an LCD. The input device 404 is, for example, a touch panel sensor or a button switch.

[0109] Examples of presentation devices other than the display device 402 include an audio device 405 that outputs sound, a lighting device that emits light (not shown), and a vibration generating mechanism that generates vibrations (not shown). When an audio device is used as the guide presenter, the guide for golf play is presented by, for example, music, voice, electronic sound, sound effect, or some other sound. When a lighting device is used as the guide presenter, the guide or support content is presented by blinking light or changing the light color. In the case of a vibration generating mechanism, the guide for golf play is presented by vibration.

[0111] The portable device used for the terminal device 400 includes a portable information terminal device such as a smartphone or a tablet terminal, a wearable terminal that can be worn by a user, etc. In addition, the terminal device 400 may be a well-known golf rangefinder that uses a laser to measure the distance from a user to a target. From the viewpoint of achieving compatibility between golf play and display visibility, it is preferable to use a wearable terminal as the terminal device 400.

[0112] Examples of wearable devices include smart glasses, eyeglass-type wearable devices, and smart watches. Among wearable devices, wearable devices that are attached to the head (head-mounted wearable devices), such as smart glasses and eyeglass-type wearable devices, are more preferable because they allow you to view guide displays and support content displays without stopping your golf game. When a head-mounted wearable terminal is applied as the terminal device 400, the head camera 602H of the photographing unit 600 is configured with a camera 406 equipped on the head-mounted wearable terminal used as the terminal device 400.

In this case, the terminal device 400 can take on the overall management function of the system S, the function of generating and providing guide information, etc. together with the control unit 350 or in place of the control unit 350.

[0113] [2. Control] Next, a specific example of control for providing guidance in the present system S will be described. In the control unit 350, the control device 351 constantly receives, as monitor 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, 602H of the photographing unit 600, and the second camera 702 of the club unit 700, cup-in information from the first sensor 252 of the cup unit 250, impact information from the impact sensor included in the second sensor 704 of the club unit 700 and angle data from the angle sensor, and impact vibration / impact sound information from the impact vibration / impact sound sensor 710 of the club unit 700.

[0114] 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 it as big data, and based on this monitor information, generates guide information to provide guidance to the user on their golf play.

[0115] <Guide presentation> First, an example of control for presenting a guide (instruction) for playing golf will be described. The control device 351 analyzes the acquired video data using well-known image analysis technology to calculate play situation estimation data. The play situation estimation data is data estimated from the video of the current play situation. 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 line of sight, head position, stance, distance to the pin P, and the like. The play situation estimation data enables the control unit 350 to grasp (estimate) the play situation based on the monitor information.

[0116] The control device 351 generates guide information based on the calculated play situation estimation data and the sample (model play) data. The guide information is advice (guide) for achieving a better hit based on the current play situation (the user's current position, the user's posture before swinging, head-up analysis, head-up check, the user's line of sight, head position, stance, distance to the pin P, etc.). Specifically, tips for playing golf, such as a sample swing trajectory, a sample form, swing rhythm, ball launch direction, standing position, foot width, accurate impact, etc., are presented in the form of pictures, photos, videos, voices, rhythmic sounds, characters, etc. In addition, the playing form of a master or expert, such as a professional golf player, can also be presented as a model play.

[0117] Model data that serves as a guide for golf play, and various video, image, and audio data for generating guide information are stored in advance in the storage device 354. Model data includes, for example, models of the user's posture before swinging, the user's line of sight, head position, stance, body movement, and golf club trajectory.

[0118] The control device 351 transmits the generated guide information to the terminal device 400. The terminal device 400 outputs guide content for golf play based on the guide information from the display device 402 and the audio device 405. The destination of the guide information may be the display device 706 and the audio device 707 of the club unit 700, the other units 250 and 500, etc., in addition to the terminal device 400.

[0119] The guide content is at least one of a guide video and a guide audio. The guide video includes the user's eye position during the swing, head position, posture, head-up analysis, head-up check, hitting form, golf club stroke trajectory, head angle, ball launch angle, head speed, strike strength, swing tempo, glove path (trajectory), and putter face direction (angle). The guide voice may be a metronome sound (including music, voice, and other rhythmic sounds) that guides the swing rhythm of the golf club, advice (voice comments) for improving golf play, etc. Also, the device may be connected to an interactive online golf lesson service via the Internet.

[0120] As a guide for playing golf, a result predicted from a current playing situation may be presented, such as a predicted ball trajectory, a predicted swing trajectory, a predicted form, etc.

[0121] When generating guide information, the control device 351 can take into account monitor information accumulated as big data, driving range information regarding the gradient and grain of the green G, and personal information regarding the user's age, sex, physique, constitution, height, weight, golfing skills, and the like. Taking into account various pieces of information can improve the accuracy of the guide to golf play provided by the guide information. In addition, by adding the history of golf play information about the user to the guide information, the user's "habits" can be more easily reflected, and personalized golf play guide can be provided. In addition, the control device 301 may have a function (generation AI) of automatically generating guide information by learning various collected and accumulated data.

[0122] <Laser light guide> In the present system S, a laser beam (guide laser beam) is irradiated from the first illuminator 504 of the pin unit 500 toward the hitting area T2. Meanwhile, a first light receiver 708 is provided in the club unit 700 of the golf club 1 used by the user of the hitting area T2. Therefore, when the user stands at an appropriate position relative to the pin unit 500, the first light receiver 708 of the club unit 700 receives the laser beam from the first illuminator 504. When the first light receiver 708 receives the guide laser beam, a display in the system S displays the same. Examples of the display include the display 402 of the terminal device 400 and the display device 706 of the club unit 700. When the first light receiver 708 receives the guide laser beam, a speaker in the system S may output a voice to notify the user of the same. The speakers in the system S include the audio device 405 of the terminal device 400, the audio device 256 of the cup C, the audio device 506 of the pin P, the audio device 707 of the club unit 700, and the like.

[0123] Also, a laser beam (guide sub-laser beam) is emitted from the second illuminator 705 of the club unit 700. When the user stands at an appropriate position relative to the pin P, the laser beam from the second illuminator 705 is emitted toward the pin P (pin unit 500). On the other hand, the pin unit 500 is provided with a second light receiver 505. Therefore, when the user stands at an appropriate position relative to the pin unit 500, the second light receiver 505 of the pin unit 500 receives the laser beam from the second illuminator 705 of the club unit 700. When the second light receiver 505 receives the guide sub-laser beam, the display in the system S displays the same. Examples of the display include the display 402 of the terminal device 400 and the display device 706 of the club unit 700. When the second light receiver 505 receives the guide sub-laser beam, the speaker in the system S may output a voice to notify the user of the same. The speakers in the system S include the audio device 405 of the terminal device 400, the audio device 256 of the cup C, the audio device 506 of the pin P, the audio device 707 of the club unit 700, and the like.

[0124] As described above, when the first light receiver 708 receives the guide laser beam, the display in the system S displays that fact, and when the second light receiver 505 receives the guide sub-laser beam, the display in the system S displays that fact, so that the user can confirm by the display that he or she is standing at an appropriate position with respect to the pin unit 500. The content of the display may be anything as long as it notifies the user that he or she is standing at an appropriate position with respect to the pin unit 500. The trajectories of the laser light from the first light receiver 708 and the laser light from the second light receiver 505 function as guide lines showing the trajectory of the ball B, so that the user can grasp the direction of the ball B while standing at an appropriate position relative to the pin unit 500. Therefore, a visual guide regarding putting (hitting the ball B) can be provided to the user.

[0125] In addition, it is possible to present guide light in both directions, using the first illuminator 504 of the pin unit 500 and the second illuminator 705 of the club unit 700, with laser light from the front and laser light from the rear. The two-way guide light can provide more reliable guidance. The irradiation angle between the first illuminator 504 of the pin unit 500 and the second illuminator 705 of the club unit 700 can be automatically adjusted based on the above-mentioned monitor information and video data analysis results. This allows accurate guidance that reflects the current playing situation by adjusting the direction of the laser light.

[0126] <Feedback on current situation analysis results> Furthermore, the control device 351 can provide feedback on the play result after the hit is completed based on the result of analyzing the video data. In this case, the control device 351 identifies the swing made by the user in the video based on the result of analyzing the video data, analyzes the identified swing, and tracks the hit 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).

[0127] Examples of analysis items for the user's form include the user's eye position, head position, posture, head-up analysis, and head-up check. Examples of analysis items for the movement of the golf club (head) include the stroke trajectory of the golf club, head angle, head speed, strength 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 flow.

[0128] Examples of analysis items for the movement of golf ball B include the speed of golf ball B, the launch angle (launch direction) of golf ball B, and the flight distance of golf ball B. The control device 351 calculates analysis result data for each of the above items by analyzing the video data, and generates the calculated various analysis result data as practice support information. The analysis result data generated as support information is used as information for displaying the analysis results and evaluation of the golf play for each of the above items.

[0129] 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 evaluation of the golf play for each of the above items on the display 402 as practice support content based on the received analysis result data (support information). In other words, feedback on the golf play results is provided. Such feedback contributes to the improvement of the user's golf technique. Also, visualizing one's own play as numerical values ​​and images contributes to improving the enjoyment of golf.

[0130] Examples of analysis results of golf play displayed as support contents on the display 402 are listed below. That is, examples of support contents include the speed of golf ball B, the launch angle (launch direction) of golf ball B, the flight distance of golf ball B, the number of rotations of ball B, the rotation direction of ball B, the rotation speed, ball quality, the quality of rotation, a video recording the form of the user during a swing, a series of high-speed photographs recording the form of the user during a swing, the position of the user's line of sight during a swing, the position of the head, the posture, head-up analysis, head-up check, the stroke trajectory of the golf club, the measured head angle, the measured head speed, the measured strength of the hit, the tempo of the swing, the swing flow, and the flow of the club head. The stroke trajectory of the golf club includes the so-called glove pass. The angle of the head includes the direction (angle) of the putter face.

[0131] The feedback on the golf play result is not limited to the above-mentioned visual feedback, but may be provided by audio information (that is, auditory feedback). Specifically, the auditory feedback is to transmit the analysis result of the golf play by voice. Specifically, it is possible to output voice such as "Nice shot," "It's off," "It's hooked," "It's open," "It's off by n (n is any number) degrees," "It's hooked by n (n is any number) degrees," "It's open by n (n is any number) degrees," etc. in response to the swing made by the user. These voices can be provided in combination with the above visual feedback.

[0132] In this case, the storage device 354 of the control unit 350 is provided with a database that stores various voice data (audio data) to be used for auditory feedback. The control device 351 extracts voice data to be provided to the user from the database based on the various analysis result data calculated, and generates practice support information including this voice data. The terminal device 400 outputs a sound based on the transmitted sound data. For example, headphones or earphones can be used to output the sound. Note that the sound output may be performed by an audio device of any device in the system S, not limited to the terminal device 400.

[0133] <Banner Ad> The control device 351 may generate banner advertisement display information and transmit it to the terminal device 400 of the user in association with providing the above-mentioned guide information and providing feedback on the golf play result.

[0134] The banner advertisement display information is information for displaying a banner advertisement image (a small advertisement displayed in a part of the screen). In this case, the terminal device 400 displays the banner advertisement in association with the provision of guide information and feedback on the golf play results. The banner advertisement may be displayed on any display device in the system S as well as on the terminal device 400 . The control device 351 may generate advertising audio output information instead of or in addition to the banner advertising display information, and transmit the generated advertising audio output information to the terminal device 400 of the user. In this case, the terminal device 400 outputs the advertising audio in association with the feedback on the golf play result. The content of the output video and audio is not limited to advertisements and may be any video or audio (e.g., ASMR, etc.).

[0135] In addition, the contents provided from the control unit 350 to the terminal device 400 and other devices 250, 500, 700 in this system S are not limited to those mentioned above. For example, audio and video guidance for "prize presentation", advertising videos and audio, points awarded at stores and websites, miles, mileage, stay mileage, discount tickets, service coupons, music, support audio, lighting effects, etc. may be provided.

[0136] In this case, the storage device 354 of the control unit 350 is provided with a database that accumulates a large amount of information (including advertising video signals) related to advertising videos, advertising audio, point allocation in stores and websites, music, support audio, lighting effects, etc. The control unit 350 extracts information related to advertising videos, advertising audio, point allocation in stores and websites, miles, mileage, stay mileage, discount tickets, service coupons, music, support audio, lighting effects, etc. from the database in response to, for example, a cup-in, and transmits it to the terminal device 400. The support audio is audio that enhances the enjoyment of playing golf, specifically, cheers, cheers, applause, etc. from the gallery. The lighting effects are effects that enhance the enjoyment of the user during golf by controlling the on / off, color, brightness, etc. of the light source device in the system S. The lighting effects provide illumination, neon, lights, spotlights, rotating spotlights, mirror balls, LED lighting, etc. The lighting effects may be accompanied by music playback. A user can select a desired music genre or a desired piece of music, such as disco, gravure music, classical music, pop music, enka, etc. In the lighting production, it is preferable to change the control of the light source device according to the selected music genre.

[0137] The timing for providing banner advertisement images, advertisement audio, music, etc. is not limited to when the ball goes in. Advertisement images, advertisement audio, music, radio broadcasts, movies, etc. can be provided at any time during practice with the practice machine T. Providing "music" as described above includes playing music based on a playlist of desired music genres or desired songs created by the user, and playing music selected by a DJ (disc jockey). The user may be able to request a desired song in relation to the DJ's selection. The music provided may also be so-called "karaoke." In this case, the user can sing along with the karaoke performance. The user can arbitrarily switch on and off the playback of audio and video such as advertising videos, advertising audio, music, radio broadcasts, movies, television, video distribution services, etc. In other words, the user can individually select, for example, from the terminal device 400, whether or not the various contents described above are provided.

[0138] In addition, the terminal device 400 may provide a competitive game function, a putting game, an approach game, and the like, linked to the acquired monitor information. When the user's terminal device 400 is a wearable device (head-mounted wearable device) that is worn on the head, such as smart glasses or a glasses-type wearable device, the above-mentioned various guide displays and images of the support content are superimposed on the real world and displayed on the display 402 of the terminal device 400. In this way, by providing the guide display and support content as AR (Augmented Reality), VR (Virtual Reality), or MR (Mixed Reality), the user's enjoyment of playing golf can be further enhanced.

[0139] If the user's terminal device 400 is a wearable device that is worn on the head (head-mounted wearable device) such as smart glasses or a glasses-type wearable device, the display 402 of the terminal device 400 can be used to play audio and video such as advertising videos, advertising audio, music, radio broadcasts, and movies, browse websites, and view various file documents while playing golf or moving between courses. In other words, while playing golf, a user can have an auditory and visual experience or perform auditory and visual tasks separate from golf. The user can appropriately select the above-mentioned various guide displays and support contents from the terminal device 400 and receive the support contents in a desired combination.

[0140] 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 storing the analysis results of the video data and the generated support information as big data in the control unit 350, a data platform that accumulates golf play information can be provided. Big data can be mutually utilized by multiple golf training machines.

[0141] In the golf practice system S shown in Fig. 37, a display (monitor) 1M for a user is provided in the hitting area T2. This monitor 1M is an example of a display device for displaying various information, and is installed near the user. The monitor 1M is provided with a control device 901, a display device 902, a communication device 903, an input device 904, an audio device 905, a camera 906, a sensor 907, a lighting device 908, and the like.

In other words, the monitor 1M functions as one of the devices in the practice system S, and can be configured as a multi-functional AI device that can link with other devices in the system S, display various information to the user, output audio, perform specified functions in response to specified voice input such as "Alexa (registered trademark)," "OK Google (registered trademark)," or "Hey Siri (registered trademark)," and emit light.

[0142] The monitor 1M may display the various guides described above, support contents, video and still images of the user's form, weather, current news, the user's score, ranking, and the like. The monitor 1M allows the user to easily check the visual information provided by the system S. In addition, the monitor 1M functions as one element of the golf practice system S in cooperation with other devices in the system S. For example, the user may use the monitor 1M to connect to an interactive online golf lesson service via the Internet.

[0143] Also, an electronic scoreboard 800 (display) may be installed at any location in the golf practice system S (for example, behind the cup area T1). The electronic scoreboard 800 is an example of a display for displaying various information in the golf practice system S, and is preferably a large display device from the viewpoint of ensuring visibility. However, the size of the electronic scoreboard 800 is not particularly limited. The electronic scoreboard 800 may be configured as an information terminal device including additional mechanisms such as a control device 801, a display device 802, a communication device 803, an input device 804, an audio device 805, a camera 806, a sensor 807, and a lighting device 808, and can function as one of the devices constituting the system S.

[0144] As the sensor 807, for example, a speed sensor, an acceleration sensor, a gyro sensor, a magnetic sensor, a biometric authentication sensor, an air pressure sensor (pressure sensor), a temperature sensor, a microphone (sound pressure sensor), a direction sensor, a proximity sensor, a brightness sensor (ambient light sensor), a human sensor, an anemometer, a wind vane, an infrared sensor, an infrared camera, a snow depth meter (such as a snow depth meter based on laser reflection or an image captured by a camera), etc. may be provided. That is, the electronic bulletin board 800 functions as one of the devices in the practice system S, and can be configured as a multi-functional AI device that cooperates with other devices in the practice system S, displays various information to the user, outputs voice, performs a predetermined function in response to a predetermined voice input such as "Alexa (registered trademark)", "OK Google (registered trademark)", or "Hey Siri (registered trademark)", and emits light.

[0145] The display of various information on the electronic scoreboard 800 is controlled by, for example, the control unit 350. The electronic scoreboard 800 may be controlled not only by the control unit 350 but also by any of the cup unit 250, the control unit 350, the terminal device 400, the pin unit 500, the photographing unit 600, and the club unit 700 in the system S. The electronic scoreboard 800 may display the above-mentioned various guide displays and support contents. In addition to the above-mentioned guides and contents, any information such as weather, current news, user scores, and rankings may be displayed on the electronic scoreboard 800. Also, instead of or in addition to the electronic scoreboard 800, a projector may be provided. Images can be projected into the system S by projection mapping using the projector.

[0146] Any of the cameras provided within the golf practice system S may be configured as a 3D camera. Furthermore, each device in the golf practice system S may be configured to share its own power status (eg, remaining battery level) and operating status (meters). In addition, since the photographing units 600 are arranged to surround the user standing in the hitting area T2, the photographing units 600 can photograph a whole body (all around) image of the user. Using such image information, measurement data can be obtained when custom-making clothing, accessories, tools, etc., such as golf wear, golf caps, golf shoes, and golf clubs. In addition, using such image information, icons, avatars, and characters (two-dimensional characters, three-dimensional characters) that users use on SNS on the Internet can be created. The created avatars can be used in a three-dimensional virtual space constructed on a computer, such as the Metaverse.

[0147] [3. Effects] According to the golf training system S of the present embodiment, since it has the above-mentioned configuration, it has the following operational effects.

[0148] (1) According to the present 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 taken from the pin P toward the hitting area T2 (rearward) by the first camera 502 of the pin unit 500; video data taken from the head toward the front by the second camera 702 of the club unit 700; hitting data and head angle data detected by the second sensor 704 of the club unit 700; and hitting vibration / hit sound information detected by the hitting vibration / hit 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 for providing a guide to the user's golf play according to the playing situation. The terminal device 400 provides the user with a guide according to the guide information in advance (in advance) before the user hits the ball. Guidance is provided based on monitor information obtained from multiple monitor information sources (cup unit 250, pin unit 500, club unit 700) arranged at the front (cup C side) and rear (hitting area T2 side) of the training machine T. The types of monitor information include multiple types, including video data, hitting information, vibration information, and cup-in information. Therefore, highly accurate guidance that takes into account multiple elements is provided. This can improve the effectiveness of training. Here, since the monitor information includes impact vibration / impact sound information related to the (emphasized) impact vibration / impact sound generated by the diaphragm member 200, it is possible to provide a guide based on the impact vibration / impact sound information. For example, the correlation between the impact vibration / impact sound information and the impact information (other monitor information) (for example, the relationship between the impact vibration or impact sound and the quality of the impact, etc.) can be analyzed and the analysis results can be presented, or the analysis results can be accumulated and fed back to the user. In addition, the impact vibration / impact sound information can be visualized (made visible) using numerical values, graphs, etc., and the impact vibration / impact sound information can be accumulated as big data. In addition, it is possible to present the guide light in both directions, using the first illuminator 504 of the pin unit 500 and the second illuminator 705 of the club unit 700, with the laser light from the front and the laser light from the rear. Therefore, more accurate guidance is possible compared to a structure in which the guide light is irradiated in one direction from the golf club.

[0149] 38(A) and (B) are side views of the golf club 1. The golf club 1 shown in FIG. 38(A) is provided with a diaphragm member 200 over both the head 3 and the hosel 4. The hosel 4 has two bent portions and is bent in such a way that the upper end on the shaft 5 side is located forward of the lower end on the head 3 side. Here, the diaphragm member 200 is attached over the striking surface 2 of the head 3 and the surface facing the front of the hosel 4. In other words, the diaphragm member 200 can be attached to the golf club 1 later, and is also detachable from the golf club 1. The golf club 1 shown in FIG. 38(C) is a perspective view of the golf club 1 in FIG. 38(A), and shows the golf club 1 and the diaphragm member 200 disassembled. Not only in the golf club 1 shown in Fig. 38(A), but in any golf club 1, the thickness of the diaphragm member 200 can be set appropriately, and it may be made thicker or thinner. Also, the golf club 1 may be provided with the diaphragm member 200 and a balance member (weight). Also, the balance of the golf club 1 may be adjusted by the weight of the diaphragm member 200. In this case, the diaphragm member 200 also serves as a balance adjustment function (weight).

[0150] In the golf club 1 shown in FIG. 38(B), the head 3 is formed so that the thickness of the side where the striking surface 2 is located is thin. By forming the thickness of the side where the striking surface 2 is located thin in this way, the striking surface 2 of the head 3 itself functions to emphasize the impact vibration and impact sound generated when hitting a golf ball. In other words, the striking surface 2 of the head 3 functions as a vibration plate member. In this case, too, the hitting feel and impact sound can be improved compared to existing golf clubs. Note that in the golf club 1 shown in FIG. 38(B), a weight may be attached to the head 3 to adjust the balance. Moreover, the golf club 1 shown in Fig. 38(D) is an exploded perspective view showing a modified example of the golf club 1 shown in Fig. 38(C). The golf club 1 shown in Fig. 38(D) is different from the golf club 1 shown in Fig. 38(C) in that the hosel 4 extends linearly, but the rest of the configuration is the same.

[0151] 39(A), a vibration plate member 200 (fourth impact vibration / impact sound emphasizing mechanism) is provided across the head 3, hosel 4, and shaft 5. The hosel 4 has two bent portions, and is bent in such a way that the upper end portion on the shaft 5 side is located forward of the lower end portion on the head 3 side. 39(B) does not have a hosel 4, and the shaft 5 has two bent portions and is bent in such a way that the upper side is positioned forward of the lower end portion on the head 3 side. In the golf club 1 shown in FIG. 39(B), a vibration plate member 200 is provided across the head 3 and the shaft 5.

[0152] The golf club 1 shown in Fig. 39(C) has the same configuration as the golf club 1 shown in Fig. 39(A) except that the hosel 4 is a straight neck type having a straight line shape. The diaphragm member 200 is provided across the head 3, the hosel 4 and the shaft 5. The golf club 1 shown in Fig. 39(D) has a common structure with the golf club 1 shown in Fig. 39(B) except that the shaft 5 is a straight neck type having a straight line shape. The diaphragm member 200 is provided across the head 3 and the shaft 5. According to the golf club 1 shown in Figures 39(A) to (D), the vibration plate member 200 is provided across the head 3, the hosel 4, and the shaft 5, or across the head 3 and the shaft 5, so that vibrations generated by hitting a golf ball are easily transmitted to the grip 6. Note that Figures 39(A) to (D) show the golf club 1 and the vibration plate member 200 in an exploded view.

[0153] The golf club 1 shown in FIG. 40(A) is provided with a diaphragm member 200 extending over both the head 3 and the hosel 4. The diaphragm member 200 includes a first surface portion 200H attached to the striking surface 2 of the head 3, and a second surface portion 200J extending upward from the first surface portion 200H. The second surface portion 200J of the diaphragm member 200 is integral with the hosel 4. The hosel 4 has two bent portions, and is bent in such a way that the upper end portion on the shaft 5 side is located forward of the lower end portion on the head 3 side. The first surface portion 200H of the diaphragm member 200 attached to the striking surface 2 of the head 3 also functions as a so-called insert. The golf club 1 shown in FIG. 40(B) differs from the golf club 1 shown in FIG. 40(A) in that a first surface portion 200H and a second surface portion 200J are formed from separate members, but the rest are the same.

[0154] The golf club 1 shown in FIG. 40(C) is provided with a vibration plate member 200 over both the head 3 and the hosel 4. Here, the hosel 4 has two bent portions, and is bent in such a way that the upper end portion on the shaft 5 side is located forward of the lower end portion on the head 3 side, and has a triangular thin plate portion 4T standing upright from the upper surface of the head 3. The vibration plate member 200 includes a first surface portion 200H attached to the striking surface 2 of the head 3, and a second surface portion 200F provided on the hosel 4. This second surface portion 200F forms a fin-shaped portion made of a triangular thin plate provided between the head 3 and the hosel 4. The second surface portion 200F (fin-shaped portion) is provided on the thin plate portion 4T of the hosel 4. The fin-shaped second surface portion 200F may be provided integrally with the hosel 4, or may be detachable (retrofittable) from the hosel 4. In this case, the first surface portion 200H of the vibration transmission member 200 also functions as a so-called insert. The second surface portion 200F of the vibration transmission member 200 functions as a so-called fin. The thickness of the thin plate portion 4T may be set thin so that the thin plate portion 4T itself functions as the fin-shaped second surface portion 200F. As shown by the dashed line in FIG. 40(C), the illumination member 4E may be disposed in a planar or chain-like manner on the top surface of the second surface portion 200F (fin-shaped portion) and the thin plate portion 4T. The illumination member 4E may be disposed only on one of the second surface portion 200F and the thin plate portion 4T.

[0155] The golf club 1 shown in FIG. 40(D) ​​differs from the golf club 1 shown in FIG. 40(C) in that a fin-shaped diaphragm member 200F (200) is provided only on the hosel 4, but the other configurations are the same as those of the golf club 1 shown in FIG. 40(C). This diaphragm member 200F forms a fin-shaped portion made of a triangular thin plate provided between the head 3 and the hosel 4. The fin-shaped diaphragm member 200F may be provided integrally with the hosel 4, or may be detachable (addable later) from the hosel 4. In this case, the diaphragm member 200F functions as a so-called fin. In addition, in Figures 40 (A) to (D), the shape (neck shape) of the hosel 4 is not limited to the example shown in the figure, and well-known shapes such as a straight neck, a gooseneck, and a crank neck can be freely applied.

[0156] In the golf club 1 shown in FIG. 41(A), a detachable unit 70 is detachably attached to the inside of the shaft hollow portion 9 and the grip hollow portion 10. As shown in FIG. The detachable unit 70 includes a main body 70A and a hollow portion 70B formed inside the main body 70A. The main body 70A is a cylindrical member that extends in the direction in which the shaft 5 extends (axial direction) and conforms to the inner circumferential shapes of the shaft hollow portion 9 and the grip hollow portion 10.

[0157] The shape of the main body 70A of the detachment unit 70 may be any shape as long as it is cylindrical and conforms to the inner circumferential shape of the shaft hollow portion 9 and the grip hollow portion 10, and the hollow portion 70B is formed inside. As an example, the main body 70A has a framework structure that combines a plurality of vertical beams 70V extending along the axial direction of the shaft 5 and a plurality of horizontal beams 70H along a cross section in the axial direction, as shown in FIG. 41(B). The vertical beams 70V are disposed between the upper end portion 70U and the lower end portion 70D at a distance from each other. The horizontal beams 70H are disposed perpendicular to the vertical beams 70V. The vertical beams 70V and the horizontal beams 70H form a lattice-like framework structure.

[0158] The main body 70A (detachable unit 70) functions as a reinforcing member that reinforces the strength of the shaft 5 from the inner peripheral surface side. The main body 70A (detachable unit 70) reinforces the strength of the shaft 5, and thus the plate thickness of the peripheral surface of the shaft 5 (the peripheral surface surrounding the shaft hollow portion 9) can be made thinner. This makes it easier for the shaft 5 to transmit vibrations, and therefore the vibrations transmitted to the grip 6 can be strengthened. As a modified example of the main body 70A (detachable unit 70) shown in FIG. 41(B), the horizontal beam 70H may be omitted and the main body 70A may be configured with one or a plurality of vertical beams 70V. The shape of the main body 70A is not limited to the above-mentioned framework structure, but may be a tubular structure surrounded by a wall surface, and is also not limited to a cylindrical shape, but may be a rectangular tubular shape.

[0159] 41(A) and (B) is a cartridge type that has a cylindrical shape that fits the inner circumferential shapes of the shaft hollow portion 9 and the grip hollow portion 10 and is inserted into and removed from the shaft hollow portion 9 and the grip hollow portion 10. In this case, the golf club 1 can be said to have a dual structure with the detachable unit 70 built in. Fig. 41(C) shows a modified example of the shape of the detachable unit 70. The shape of the detachable unit 70 shown in Fig. 41(C) is a capsule type with both upper and lower ends being substantially hemispherical. The shape of the detachable unit 70 shown in Fig. 41(D) is a modified example of the capsule type, in which the lower end (one end) is curved and pointed more sharply than the upper end (the other end).

[0160] The detachable unit 70 shown in Figures 41(A) to (D) may be removably attached with its lower end in contact with the hosel 4, or may be built into the shaft hollow portion 9 and the grip hollow portion 10 with the lower end spaced above the hosel 4. 41(A) to (D) may have an upper end portion built into the grip hollow portion 10, or may be built into the shaft hollow portion 9. The position of the upper end portion of the detachable unit 70 may be located at the upper end portion of the grip hollow portion 10 or the shaft hollow portion 9, or may be spaced downward from the upper end portions of the grip hollow portion 10 or the shaft hollow portion 9.

[0161] The outer peripheral surface of the detachable unit 70 may or may not be in contact with the inner peripheral surfaces of the shaft hollow portion 9 and the grip hollow portion 10. When the outer peripheral surface of the detachable unit 70 is not in contact with the inner peripheral surfaces of the shaft hollow portion 9 and the grip hollow portion 10, for example, a resin ring may be provided on the outer peripheral surface of the detachable unit 70 to close the gap between the outer peripheral surface of the shaft hollow portion 9 and the grip hollow portion 10. The detachable unit 70 may have various electric devices 72 built therein, such as a pickup, an amplifier, a speaker, a microphone, an actuator, a communication device, a battery, a motor, etc. For example, if a sensor is provided in the detachable unit 70, it is possible to detect information inside the shaft 5. Specifically, if a vibration sensor is provided in the detachable unit 70, it is possible to detect vibration information inside the shaft 5. The information inside the shaft 5 can be, for example, one of the pieces of information handled in the above-mentioned golf practice system. The diaphragm member 200 may have a structure that easily generates sound in response to being struck, that is, a structure of a percussion instrument. In this case, the diaphragm member 200 can have the structures of various percussion instruments such as a steel pan, a gong, a drum, a drum, and a cymbal. The diaphragm member 200 may be attached to the golf club 1 later, or may be pre-installed on the golf club 1 (genuine part). In addition, in each of the above embodiments and modified examples, the shapes (neck shapes) of the hosel 4 and shaft 5 are not limited to those described above, and well-known shapes such as a straight neck, gooseneck, and crank neck can be freely applied. In addition, in each of the above embodiments and modifications, the golf club is not limited to a putter, and may be any type of club, such as an iron or a driver.

[0162] 42 to 45 show a golf club 1 characterized by a surface vibration member (insert) provided on the striking surface 2 of the head 3. As shown in FIG. A striking surface (face) 2 for striking a golf ball is provided on the side of the head 3. The striking surface 2 is provided with an insert consisting of a planar vibration member 15 formed in a planar shape that vibrates when it collides with the golf ball and applies a reaction force to the golf ball. This makes it possible to efficiently apply a reaction force to the ball with a small force, thereby increasing the flight distance. The face vibration improves the feel of the impact.

[0163] As shown in Figure 43, the surface vibration member 15 has a net member 16 formed by weaving strings 19 into a net shape inside a frame 18, and a membrane member 17 that covers the entire surface of the net member 16 and is attached to the striking surface 2. This net member 16 has a structure similar to that of a tennis racket, for example. This makes it possible to efficiently apply a reaction force to the ball. It is preferable that each of the net member 16 and the membrane member 17 be individually detachable from the striking surface 2 of the head 3.

[0164] The strings 19 constituting the net member 16 include at least one of natural fibers (gut (cow gut, sheep intestines)), synthetic fibers (nylon fibers, polyester fibers), and elastic fibers (natural rubber fibers, synthetic rubber fibers), and the membrane member 17 includes at least one of metal plates, resin plates, rubber films, and leather films. In this way, the net member can be realized at low cost by reusing existing strings (tennis strings, rubber belts, etc.), and the membrane member can be realized at low cost by reusing existing membrane products (drum membranes, rubber membranes of table tennis rackets, etc.). Furthermore, the net member 16 and the membrane member 17 can be formed integrally to have a structure similar to the hitting surface structure of a table tennis racket, or the net member 16 can be made by stretching the skin of a drum across a frame material. The insert can also be made of metal. In this case, the insert can be formed in a lattice shape like the cover of a grating. Furthermore, the net member 16 constituting the surface vibration member 15 (insert) may be formed of a net-like (mesh-like) net member (mesh member) using resin fibers such as fiber reinforced plastic (FRP) or ultrafine resin fibers. 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) shape. Another specific example is a mesh member made by intertwining ultrafine resin fibers three-dimensionally. In a golf club 1 having a surface vibration member (insert) using a mesh member, vibrations generated when hitting a golf ball tend to be amplified by the surface vibration member. This can improve the feel of the hit.

[0165] The insert may have a structure similar to that of a gong, i.e., the striking surface 2 of the insert is made of a raised structure, so that when a golf ball hits the striking surface 2 of this gong structure, a sound similar to that of a gong is produced. If a drum skin is stretched across a frame material as the net member 16, or if the insert striking surface 2 is made into a gong structure, a vibration sensor that detects the vibration of the drum skin or the vibration of the gong-structured insert can be provided, for example, inside the golf club head or integral with or in close proximity to the insert, and the vibration of the drum skin or the vibration of the gong-structured insert can be amplified and output as sound from a speaker.

[0166] The surface vibration member 15 is provided detachably to the head 3. This allows the user to attach or detach it according to their preference. The surface vibration member 15 can also be attached to an existing golf club. Similarly to the head cavity 7 described above, the head 3 may be provided with a hollow head cavity 7 formed inside. For example, as shown in Figs. 42 and 44, the head cavity 7 may be formed inside the head main body 14, and an opening may be provided on the side of the head cavity 7. The surface vibration member 15 (net member 16, film member 17) is attached so as to cover the opening of the head main body 14. This allows the surface vibration of the surface vibration member 15 to reverberate inside the head cavity 7, improving the feel of the impact.

[0167] An internal head wire (auxiliary vibration transmission member) 30 may be attached inside the head hollow portion 7. The internal head wire 30 is stretched inside the head hollow portion 7 and connected to the planar vibration member 15 via a connection wire 40. This allows the planar vibration of the planar vibration member 15 to be transmitted through the shaft 5 and grip 6, and can also be amplified as vibration of the internal head wire 30, improving the feel of the hit.

[0168] As shown in FIG. 44, a shaft hollow portion 9 may be provided by forming the inside of the shaft 5 hollow, similarly to the above-mentioned shaft hollow portion 9. With this configuration, the surface vibration can be reverberated inside the shaft hollow portion 9 as well, improving the feel on impact. As shown in FIG. 44, a wire 20W may be provided inside the shaft hollow portion 9. The wire 20W is stretched inside the shaft hollow portion 9 and connected to the wire 30 inside the head. With this configuration, the surface vibration of the surface vibration member 15 can be transmitted through the shaft 5 and the grip 6, and can also be amplified as vibration of the wire 20W inside the shaft, improving the feel on impact.

[0169] 45, the wire 20W in the shaft may be stretched so as to connect the grip 6 and the wire 30 in the head. In other words, the upper end of the wire 20W in the shaft may be fixed inside the grip 6 so that the vibration of the surface vibrating member 15 is transmitted through the shaft 5 and the grip 6, and also transmitted as the vibration of the wire 20W in the shaft and the grip 6. With this configuration, the vibration can be efficiently transmitted to the grip, and the hitting feeling can be further improved.

[0170] When hitting a ball with a golf club, if the golf ball hits the striking surface 2 of the insert and hits the sweet spot of the striking surface 2, a chime, gong or buzzer may sound as an electronic sound, or a voice may be used to notify the user, or the tone of the chime, gong or buzzer may be different or the voice may be changed depending on whether the sweet spot is hit or not. In this case, a sensor is provided that detects whether the golf ball has hit the sweet spot, or a sensor is provided that detects whether the golf ball has deviated from the sweet spot, and based on the detection information from this sensor (or these sensors), the chime, gong or buzzer sound is output from a speaker via an amplifier, or as a voice. Also, a mechanism may be provided that detects the vibration of the surface vibration member 15, amplifies it electrically, and produces sound. A specific example of this mechanism is a structure in which the surface vibration member 15 is formed in a net shape by weaving string-like metal (magnetic) material into a net shape, and a pickup coil arranged close to the surface vibration member 15 converts the vibration of the surface vibration member 15 into an electrical signal, which is then amplified by an amplifier to produce sound.

[0171] Also, as shown in Figure 44, the inner surface of the insert can be directly connected to the auxiliary vibration transmission member (wire 30 inside the head). In this way, vibrations from the insert can be directly transmitted to the wire 30 inside the head, improving the transmission efficiency and contributing to an improved feel. Of course, the above-mentioned surface vibration member 15 (insert) can also be applied to a golf club with a hosel. For example, the above-mentioned surface vibration member 15 can be attached to the head or hosel of the hitting surface of a golf club with a hosel.

[0172] As shown in Figure 46 (A), in a golf club 1 with a hosel, a planar vibration member 15 can be attached to both the head 3 and the hosel 4. This planar vibration member 15 is provided integrally from the striking surface 2 of the head 3 to the hosel 4, and is configured as a planar member that vibrates planarly upon impact with a golf ball. In this case, a wide area for planar vibration can be ensured, making it easy to emphasize the vibration. 46(B), in the golf club 1 with a hosel, a planar vibration member 15 may be provided from the striking surface 2 of the head 3 to the hosel 4 and shaft 5. In this case, a wider area for planar vibration can be ensured, making it easier to emphasize the vibration. As shown in Figure 46(C), in a golf club 1 with a hosel, a planar vibration member 15 may be provided from the striking surface 2 of the head 3 to the hosel 4, shaft 5, and grip 6. In this case, a wider area for planar vibration can be ensured, and the user directly touches the planar vibration member 15 with the grip 6, making it easier to emphasize the vibration. When the above-mentioned gong structure is adopted in the golf club 1 of Figures 46(A) to (C), the portion of the planar vibration member 15 provided on the striking surface 2 of the head 3 forms a gong structure (hanging structure). 46(A) to (C) show an exploded view of the golf club 1 and the planar vibration member 15. In the golf club 1 of Fig. 46(A) to (C), the shape of the hosel 4 is not limited to the shape shown in the drawings, and any well-known shape such as a straight neck, a gooseneck, a crank neck, a trapezoidal shape, or a rectangular shape can be freely applied. In the golf club 1 shown in Figs. 46(A) to (C), the planar vibration member 15 (insert) may be formed of a net-like (mesh-like) net member (mesh member) using resin fibers such as fiber-reinforced plastic or ultrafine resin fibers. A specific example of a mesh member using 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 (mesh-like). Another specific example is a mesh member made of a mat body in which ultrafine resin fibers are entangled in a three-dimensional mesh shape. A planar vibration member 15 using a mesh member made of such resin fibers tends to easily transmit vibrations. This can improve the hitting feel.

[0173] In the golf club 1 shown in FIG. 47(A), the head 3, the hosel 4, and the shaft 5 are formed from a framework 1F. The framework 1F is made of framework (framework, frame) members that form the outlines of the head 3, the hosel 4, and the shaft 5. A vibration plate member 200 is attached to the front-facing surface of the framework 1F, and is provided across the head 3, the hosel 4, and the shaft 5. Only a part of the head 3, the hosel 4, and the shaft 5 may be formed from the framework. For example, the hosel 4 and the shaft 5, excluding the head 3, may be formed from the framework. The vibration plate member 200 may be extended to the grip 6, not shown. In the illustrated example, the framework 1F made of two members forms the hosel 4 and the shaft 5, but the framework 1F forming the hosel 4 and the shaft 5 may be formed from one member or two or more members.

[0174] In the golf club 1 shown in FIG. 47(B), the hosel 4 and the shaft 5 are each formed of a band-shaped member 4G, 5G. Each band-shaped member 4G, 5G is a plate member extending in a band shape in the axial direction of the golf club 1. A vibration plate member 200 is attached across the head 3, the hosel 4 (band-shaped member 4G) and the shaft 5 (band-shaped member 5G). Note that only the head 3, the hosel 4 or the shaft 5 may be formed of a band-shaped member. Since the hosel 4 and the shaft 5 are formed of the band-shaped members 4G, 5G, vibrations are easily transmitted. Note that the vibration plate member 200 may be extended to the grip 6 not shown.

[0175] In the golf club 1 shown in FIG. 47(C), the upper portion of the shaft 5 forms an expanded portion having a larger diameter than the other portions. This expanded portion functions as the grip 6. In other words, the golf club 1 shown in FIG. 47(C) has a structure in which the shaft 5 and the grip 6 are integrated. A diaphragm member 200 is attached to the golf club 1, and is provided across the head 3, hosel 4, shaft 5, and grip 6. In the diaphragm member 200, the portion corresponding to the grip 6 forms an expanded portion having a larger width dimension than the other portions. Because the shaft 5 and the grip 6 are integrated, vibrations are more easily transmitted to the grip 6 than in a structure in which the shaft 5 and the grip 6 are separate. In addition, because the upper portion of the shaft 5 forms a widened portion, the thickness of the gripping member (urethane, etc.) provided on the grip 6 can be made thinner. This makes it easier for vibrations to be transmitted to the user's hand.

[0176] In the golf club 1 shown in FIG. 47(C), the upper portion of the shaft 5 forms an expanded portion having a larger diameter than the other portions. This expanded portion functions as the grip 6. In other words, the golf club 1 shown in FIG. 47(C) has a structure in which the shaft 5 and the grip 6 are integrated. A diaphragm member 200 is attached to the golf club 1, and is provided across the head 3, hosel 4, shaft 5, and grip 6. In the diaphragm member 200, the portion corresponding to the grip 6 forms an expanded portion having a larger width dimension than the other portions.

[0177] The golf club 1 shown in Fig. 47(D) is a modified version of the golf club 1 shown in Fig. 47(B), in which the upper portion of the shaft 5 made of a strip-shaped member 5F forms an expanded portion having a larger diameter than the other portions. This expanded portion functions as the grip 6. A diaphragm member 200 is attached to this golf club 1, and is provided across the head 3, hosel 4, shaft 5 and grip 6. In this diaphragm member 200, the portion corresponding to the grip 6 forms an expanded portion having a larger width dimension than the other portions. 47(A)-(D) are drawn in a flat shape, but may be in any shape, such as a cylindrical shape (cylinder shape, square cylinder shape) surrounding the head 3, hosel 4, shaft 5, and grip 6 (golf club 1). The belt-shaped members 4W, 5W in Figs. 47(B) and (D) may be formed in a cylindrical shape, such as a curved semi-cylinder or a square cylinder, without being limited to a flat plate shape.

[0178] In the golf club 1 of each of the above-described embodiments and modified examples, the shape of the grip 6 is not limited to the shapes shown in the drawings, and may be any shape. Also, in the golf club 1, the shaft 5 and the grip 6 may be integrally formed. In this case, as shown in Fig. 48(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 Fig. 48(B) is similar to the golf club 1 shown in Fig. 48(A) in that 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 periphery of the grip 6. The grip member 6G is a gripping member that is held by the user of the golf club 1. 48(C), the diameter of the grip 6 may be set to be larger than the diameter of the shaft 5. In this case, the grip 6 becomes easier to hold.

[0179] The material of the grip member 6G is a material that fits softly to the user's hand. Specific examples include rubber (natural rubber) and elastomer (resin material), as well as fiber reinforced plastic (FRP), ultrafine resin fibers, and metal. Although the grip member 6G is clearly shown in FIG. 48(B) in comparison with FIG. 48(A), the grip member 6G may be provided on the grip 6 of the golf club 1 according to each of the above-mentioned embodiments and modified examples. As the 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) using 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 in which a string made of fiber reinforced plastic is woven into a flat net (mesh-like). Another specific example is a mesh member in which ultrafine resin fibers are three-dimensionally intertwined. Note that a sheet-like cover may be further provided around the net member (mesh member). In a golf club 1 having a grip member 6G using a mesh member, vibrations from the shaft 5 tend to be easily transmitted to the user's hand through the grip member 6G. This improves the hitting feeling.

[0180] The material used for the grip 6 may be rubber (natural rubber), elastomer (resin material), fiber reinforced plastic (FRP), ultrafine resin fiber, metal, etc. Note that these materials are merely examples, and the materials used for the grip 6 and the grip member 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, such as various metals such as stainless steel, titanium, mild steel, bronze, aluminum, aluminum alloy, aluminum, copper, as well as carbon, plastic, nanocellulose, carbon nanofiber, Japanese paper, leather, polyacetal, PET, glass, aluminum fiber, chemical fiber, resin, polypropylene, nanocellulose, polyester, etc.

[0181] A reinforcing member for reinforcing the strength of the shaft 5 may be built into the detachable unit 70. A reinforcing member 73 having a truss structure is built into the detachable units 70 and 71 shown in Fig. 48(D). Instead of the detachable units 70, 71, a reinforcing member for reinforcing the strength of the shaft 5 may be built into the shaft hollow portion 9 of the shaft 5. A reinforcing member 74 having a truss structure is built into the shaft hollow portion 9 of the shaft 5 shown in Figure 48(E). Furthermore, the thickness (wall thickness) of the shaft 5 may be reduced so that vibrations are more easily transmitted to the hand of the user gripping the grip 6 through the shaft 5. In this case, it can be said that the shaft 5 itself functions as a vibration transmitting member. Also, the shaft 5 may be provided with thick and thin parts, so that vibration transmissibility is ensured in the thin parts and strength is ensured in the thick parts.

[0182] In the golf club 1 according to each embodiment or modification, the axial dimension (length) of the hosel 4 is not limited. That is, the ratio of the hosel 4 to the shaft 5 is free. For example, the golf club 1 shown in FIG. 49 has a larger ratio of the length of the hosel 4 to the shaft 5 than the golf club 1 shown in FIG. 1(C) and the like. The diaphragm member 200 is provided across the head 3 and the hosel 4. In this case, the area of ​​the diaphragm member 200 is wide, and the diaphragm member 200 can transmit vibrations to a position spaced above the head 3, so that it is easy to emphasize the vibration transmitted to the user's hand.

[0183] As a modification of the golf club 1 shown in FIGS. 39(A) to (D), the diaphragm member 200 may be extended to the head 3, the hosel 4, the shaft 5 and the grip 6. In the modification, as shown in FIG. In addition, the golf club 1 may be provided with the following various functions. The various functions may include an image system, a vital data detection function, a smartphone function, a smartphone function, a communication function, an AI function, a smart speaker function, a display function, a touch panel function, a speech function (conversation function), a GPS function, a beacon function, and the like.

[0184] When the diaphragm member 200 is provided on the striking surface 2 of the head 3, the surface of the diaphragm member 200 that strikes the golf ball (face surface, striking surface) may be subjected to milling (grooving). Furthermore, when a diaphragm member 200 is provided on the striking surface 2 of the head 3, the loft angle (the degree of inclination of the club face) can be adjusted and changed by varying the thickness of the upper and lower portions of the diaphragm member 200. The diaphragm member 200 may be painted or coated with any known type of paint.

[0185] <Vibration sensor> In the modified examples of the golf club 1 described above, various electric devices, sensors, control devices (controllers), batteries, etc. may be built in. FIG. 50 is a perspective view of a golf club 1 according to a modified example. As shown in FIG. 50, the golf club 1 may have a vibration sensor 95 built into the hosel 4 to detect vibrations transmitted from the hosel 4 to the vibration transmission member 20. The vibration sensor 95 may be attached to the outer surface of the hosel 4 or may be built into the hosel 4. If a hosel cavity 8 is formed inside the hosel 4, the vibration sensor 95 may be disposed inside the hosel 4. By detecting vibrations with the vibration sensor 95, the magnitude and waveform of vibrations in the vicinity of the vibration source (striking surface 2) can be objectively captured, and the hitting feeling can be further improved. In addition, the magnitude and waveform of vibrations can be analyzed, and the effect of golf practice can be improved by utilizing the analysis results. Information detected by the vibration sensor 95 may be transmitted to a computer (not shown) by, for example, a wireless connection or a wired connection.

[0186] Also, a vibration device 96 (actuator) that vibrates based on information on vibrations detected by the vibration sensor 95 may be built into the hosel 4. When a hosel cavity 8 is formed inside the hosel 4, the vibration device 96 may be disposed inside the hosel 4. The vibration device 96 may function to directly amplify and output the vibrations detected by the vibration sensor 95, for example. By amplifying the vibrations with the vibration device 96, it is possible to increase the vibrations that are actually transmitted to the user, and the feel of the hit can be further improved.

[0187] Also, a speaker 96A that emits a sound based on information on the vibration detected by the vibration sensor 95 may be built into the hosel 4. When the hosel cavity 8 is formed inside the hosel 4, the speaker 96A including an amplifier may be disposed inside the hosel cavity 8. The speaker 96A may function to amplify and output the vibration detected by the vibration sensor 95 as sound, for example. In this way, when a golf ball is hit with one of the striking 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, the shaft 5, and the 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.

[0188] 23, another vibration device 97 (actuator) and speaker 97A may be built into the grip 6. The vibration device 97 and speaker 97A are disposed, for example, inside the grip hollow portion 10 in the grip 6. Like the vibration device 96 and speaker 96A described above, the vibration device 97 and speaker 97A function to directly amplify and output the vibration detected by the vibration sensor 95, or to directly amplify and output the vibration detected by the vibration sensor 95 as sound. By generating vibrations or outputting sounds within the grip 6, the vibrations and sounds that are actually transmitted to the user can be made even larger, resulting in a further improvement in the hitting feel.

[0189] <Transmitter> The golf club 1 may further include a transmitter 101 for transmitting information detected by the vibration sensor 95 to the outside. The transmitter 101 is built into, for example, the hosel 4. When a hosel cavity 8 is formed inside the hosel 4, the transmitter 101 may be disposed inside the hosel 4. The information detected by the vibration sensor 95 may be transmitted to an external device such as a computer (not shown) via the transmitter 101, for example, by wireless connection or wired connection.

[0190] <Rhythmbox function> The golf club 1 may include a controller 100 having a rhythm box function and a synthetic voice generating function for informing the user of the rhythm when the golf ball is hit. The controller 100 is built into the hosel 4, for example. If the hosel cavity 8 is formed inside the hosel 4, the controller 100 may be disposed inside the hosel cavity 8. A speaker 96A is connected to the output side of the controller 100. When the golf ball is hit, one of the rhythm sound and the synthetic voice generated by the controller 100 can be output from the speaker 96A by either the rhythm box function or the synthetic voice generating function of the controller 100. Note that the on / off of the rhythm box function and the synthetic voice generating 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 by an external device (e.g., a smartphone) connected by wireless connection. Also, the various functions of the controller 100 may be configured by an external device (e.g., a smartphone) connected by wireless connection.

[0191] The golf club 1 shown in Fig. 51 is a modified example of the golf club 1 shown in Fig. 50. The vibration sensor 95, the vibration device 96, the speaker 96A, the transmitter 101, and the controller 100 built into the hosel 4 of the golf club 1 shown in Fig. 23 may be built into the shaft 5. FIG. 51 shows an example of a configuration in which a vibration sensor 95', a vibration device 96', and a speaker 96A' are further built into the shaft 5 of the golf club 1 shown in FIG. Without being limited to this, all of the vibration sensor, vibration device, speaker, transmitter, and controller may be built into the shaft 5. In other words, the vibration sensor, vibration device, speaker, transmitter, and controller may be built into only one of the hosel 4 and the shaft 5, or may be built into both. Also, 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 rest may be built into the other of the hosel 4 and the shaft 5 (distributed or combined).

[0192] Furthermore, in each golf club 1 shown in FIG. 50 and FIG. 51, a liquid crystal display 102 (display device, electric display member) may be added (display function). The liquid crystal display 102 is disposed, for example, on the surface facing the upper side of the head 3, and is connected to the output side of the controller 100. In this case, the liquid crystal display 102 can display the vibration data detected by the vibration sensors 95, 95' as numerical values, graphs, etc. 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 for displaying the launch direction of the golf ball to the liquid crystal display 102 based on an instruction input from an indicator (see reference numeral 103 in FIG. 52), and controls the liquid crystal display 102 to display the launch direction of the golf ball. The indicator 103 (FIG. 52) is an input means for inputting an instruction for the launch direction of the golf ball.

[0193] The display on the liquid crystal display 102 may be an arrow indicating the direction in which the golf ball will be launched, or a series of multiple circles. In this case, the circles may be made smaller as they approach the tip indicating the direction. This configuration not only improves the hitting feel, but also allows the liquid crystal display 102 to freely display the direction in which the golf ball will be launched, improving convenience. The indicator 103 and the controller 100 can be replaced by a smartphone. In this case, it is preferable to use a wireless line for connecting the controller 100 and the liquid crystal display 102. 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 (caddie).

[0194] Furthermore, with regard to the above-mentioned display function, one or more impact sensors 104 (see FIG. 52) can be provided within the head 3, and when a golf ball hits the striking surface 2, the impact data can be detected by the impact sensors 104 and collected by the controller 100, and the impact data can be converted into numerical values, graphs, etc. and displayed on the LCD display 102.

[0195] For example, when both the rhythm box function and the display function are provided, the changeover switch SW may be used to instruct switching between the two functions, as shown in Fig. 52. In this case, when the switch SW is switched to connect to the liquid crystal display 102, the hitting direction and the quantified and graphed impact data are displayed on the liquid crystal display 102, and when the switch SW is switched to connect to the speakers 96A, 96A', one of the rhythm sounds and the synthetic voice generated by either the rhythm box function or the synthetic voice generating function of the controller 100 is output from the speakers 96A, 96A'. When the switch SW is switched to connect to both the liquid crystal display 102 and the speakers 96A, 96A', the hitting direction and the quantified and graphed striking data are displayed on the liquid crystal display 102, and either the rhythmic sound or the synthesized voice is output from the speakers 96A, 96A'.

[0196] In each golf club 1 shown in Figures 50 and 51, 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', LCD display 102, vibration device 97, and speaker 97A are not limited to the examples shown in the figures and may be any position on the golf club 1.

[0197] <Adapter> Figures 53(A) and (B) are side views for explaining yet another modified example of the above-mentioned golf club 1. Figures 53(A) and (B) show an example of a golf club 1 having a crank-shaped hosel 4 as shown in Figure 1(C), but the shape of the hosel 4 is not limited to this. One of a plurality of adapters 3A, 3B is detachably attached to the underside of the head 3 of the golf club 1. A plurality of types of these adapters 3A, 3B, which differ, for example, in shape, mass, center of gravity, etc., are prepared. For example, the adapter 3A shown in Fig. 53(B) is used when it is desired to increase the lie angle L more than the adapter 3B shown in Fig. 53(A).

[0198] It is assumed that the user of the golf club 1 or an instructor (trainer) will select one of the adapters 3A and 3B and attach it to the underside of the head 3. The 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 the adapters 3A and 3B suitable for the physique and hitting form of the user of the golf club 1, it becomes easier to optimize the swing trajectory of the golf club 1, and it becomes possible to improve the effect of practice. The lie angle L refers to the angle of the shaft 5 relative to the horizontal plane when the hitting surface 2 of the head 3 is viewed horizontally from the front, and is the angle on the user's side relative to the shaft 5. It should be noted that the examples of Figures 53(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 configurations other than the adapters 3A, 3B and their mounting method are the same as those of each embodiment.

[0199] <Weight material> 54(A) and (B) are perspective views for explaining modified examples of the head 3. As shown in these figures, the head 3 may have a built-in weight member 61 for changing the position of the center of gravity of the head 3. In this case, the position of the center of gravity may be changed by making the attachment state (position and angle) of the weight member 61 adjustable. In addition, the attachment state of the weight member 61 may be manually adjustable by the user, or a weight motor 62 (drive source) for moving the weight member 61 may be provided.

[0200] FIG. 54(A) is a perspective view showing two sets of weight members 61 and a weight motor 62 built into the upper surface of the head 3. The weight members 61 are made of a material with a density different from that of the material constituting the head 3, and are provided inside a hollow cylindrical recess formed in the upper surface of the head 3. The weight motor 62 moves the weight members 61 in the rotational direction along the inner peripheral surface of the recess, thereby changing the position of each weight member 61. With this configuration, the position of the weight members 61 can be easily changed to move the center of gravity of the head 3, providing a good hitting feel.

[0201] 54(B) is a perspective view showing weight members 61 provided inside linear recesses recessed into the top surface of the head 3. The weight motor 62 changes the position of each weight member 61 by sliding the weight members 61 along the inner peripheral surface of the recesses. Even with this configuration, the position of the weight members 61 can be easily changed to move the center of gravity of the head 3, providing a good hitting feel.

[0202] The movement of the weight member 61 may be controlled using a smartphone of the user.

[0203] An example of controlling the movement of the weight member 61 using the smartphone 65 will be described. 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 also supplies the smartphone 65 with current position information of the weight member 61 . After moving the weight member 61 to a predetermined initial position, the user can input an instruction to move the weight member 61 from the 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. The smartphone 65 can monitor and display on the display 65A an image showing the position of the weight member 61 that has been moved in response to the movement command, 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 on the display 65A of the smartphone 65 and can command the movement of the weight member 61.

[0204] When a user inputs a movement instruction to move the weight member 61 to a desired position from the smartphone 65, an instruction signal is transmitted from the smartphone 65 to the motor control unit 63. The motor control unit 63 controls the weight motor 62 based on the instruction signal to move the weight member 61. When the weight member 61 moves, 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 display 65A of the smartphone 65. In this case, the position of the weight member 61 can be adjusted using the smartphone 65 in a simple and visually understandable manner.
