DESCRIPTION OF THE EMBODIMENTS

(5) FIG. 1 is a cross-sectional view of a golf ball according to an embodiment of the disclosure. Referring to FIG. 1, according to the present embodiment, a golf ball 100 includes at least a layer of ball shell 110 (one layer is illustrated), at least a layer of ball core 120 (one layer is illustrated), and an antenna layer 130. The ball core 120 is provided in the ball shell 110, and the antenna layer 130 is provided between the ball shell 110 and the ball core 120.

(6) According to the present embodiment, a material of the antenna layer 130 includes a conductive material having fluidity or ductility, which provides a buffering or an auto-recovery effect when the golf ball takes an impact force of a hit, and maintains or restores the structural integrity after the golf ball is deformed by the impact. Such design avoids the conductivity and antenna features of the antenna layer 130 and the function of the antenna from being affected by structural deformation or fracture caused by the impact force, thereby increasing the durability and reliability of the golf ball 100.

(7) A conductive material having fluidity may be liquid metal, metal powder, electrically conductive adhesive, etc., instead of a general solid conductive material. To be more specific, a conductive material having fluidity may be selenium-graphite powder, silver paste, or special electrically conductive adhesive, but the disclosure is not limited thereto.

(8) To put it in detail, the antenna layer 130 of the present embodiment is disposed on an inner surface 110a of the ball shell 110 by printing, spraying, or coating, and then covers the outside of the ball core 120 together with the ball shell 110. Furthermore, the antenna layer 130 is provided symmetrically to a ball center C of the golf ball 100 to avoid a change in a center of gravity of the golf ball 100 into a location not as expected due to the addition of the antenna layer 130.

(9) Also, when the golf ball 100 takes a hit, the ball center C of the golf ball 100 generally takes a greater impact. In light of this, instead of being provided at or near the ball center C of the golf ball 100, the antenna layer 130 is provided between the ball shell 110 and the ball core 120 as stated above to avoid the antenna layer 130 from taking excessive impact and being damaged.

(10) FIG. 2 is a side view of a partial structure of the golf ball in FIG. 1. To make the figure more comprehensible, FIG. 2 only illustrates the ball core 120 and the antenna layer 130 of FIG. 1. The antenna layer 130 shown in FIG. 1 is merely for the purpose of demonstration. The structure of the antenna layer 130 in actual practice may be extended in a winding manner as shown in FIG. 2 and be distributed symmetrically on the inner surface 110a of the ball shell 110 (illustrated in FIG. 1). In other embodiments, the antenna layer 130 may also be extended in other manners as the disclosure does not put a restriction in this respect.

(11) Referring to FIG. 1, the golf ball 100 of the present embodiment further includes at least two chips 140, and the two chips 140 are provided on the inner surface 110a of the ball shell 110, located between the ball shell 110 and the ball core 120, and electrically connected to the antenna layer 130. The antenna layer 130 and the chips 140, for example, form a passive signal reflecting module to reflect a detecting signal from an external detecting device back to the external detecting device to inform a user the location of the golf ball 100 via the external detecting device.

(12) In the present embodiment, the two chips 140 are provided symmetrically to the ball center C of the golf ball 100 to avoid a change in the center of gravity of the golf ball 100 into a location not as expected due to the addition of the chips 140. In other embodiments, more chips 140 may be disposed and the chips 140 are also provided symmetrically to the ball center C of the golf ball 100. The disclosure puts no restriction on the number of the chips.

(13) Also, when the golf ball 100 takes a hit, the ball center C of the golf ball 100 generally takes a greater impact. In light of this, instead of being provided at or near the ball center C of the golf ball 100, the chips 140 are provided between the ball shell 110 and the ball core 120 as stated above to avoid the chips 140 from taking excessive impact and being damaged while also protecting integrity of the ball core.

(14) FIG. 3 is a cross-sectional view of a golf ball according to another embodiment of the disclosure. The differences between a golf ball 100A shown in FIG. 3 and the golf ball 100 shown in FIG. 1 are that the ball shell 110 of the golf ball 100A has multiple layers (three layers are illustrated), that the ball core 120 has multiple layers (three layers are illustrated), and that the antenna layer 130 and the chips 140 are provided on the inner surface 110a of one of the layers of the ball shell 110 and located between adjacent two layers of the ball shell 110. In the golf ball 100A, the antenna layer 130 and the chips 140 may also be provided between the innermost layer of the ball shell 110 and the outermost layer of the ball core 120 adjacent to each other. Nevertheless, the disclosure does not put a restriction in this respect.

(15) FIG. 4 is a cross-sectional view of a golf ball according to another embodiment of the disclosure. The differences between a golf ball 100B shown in FIG. 4 and the golf ball 100 shown in FIG. 1 are that the ball shell 110 of the golf ball 100B has multiple layers (two layers are illustrated), that the ball core 120 has multiple layers (four layers are illustrated), and that the antenna layer 130 and the chips 140 are provided on an inner surface 120a of one of the layers of the ball core 120 and located between adjacent two layers of the ball core 120. In the golf ball 100B, the antenna layer 130 and the chips 140 may also be provided between the innermost layer of the ball shell 110 and the outermost layer of the ball core 120 adjacent to each other. The disclosure does not put a restriction in this respect.

(16) Similar to the configuration of FIG. 1, the antenna layer 130 and the chips 140 are not provided at or near the ball center C of the golf ball 100A or the golf ball 100B in the configurations of FIG. 3 and FIG. 4, and the configurations also avoid the antenna layer 130 and the chips 140 from taking excessive impact and being damaged.

(17) The disclosure does not put restriction on a material of the ball shell 110. In any of the aforementioned embodiments, the outermost layer of the ball shell 110 may be a paint layer. In addition, the antenna layer 130 and the chips 140 may be disposed on the outer side of the outermost ball shell to be located at the outer surface of the golf ball.

(18) To sum up the above, in the golf ball of the disclosure, the antenna layer is made of a conductive material having fluidity or ductility which provides a buffering or an auto-recovery effect when the golf ball takes an impact force of a hit, and maintains or restores the structural integrity after the golf ball is deformed by the impact. Also, the antenna layer and the chip are provided symmetrically to the ball center of the golf ball to avoid a change in the center of gravity of the golf ball into a location not as expected due to the addition of the antenna layer and the chip. In addition, instead of being provided at or near the ball center of the golf ball, the antenna layer and the chip are provided between the ball shell and the ball core, thereby avoiding the antenna layer and the chip from taking excessive impact and being damaged while also protecting integrity of the ball core.

(19) It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the disclosure without departing from the scope or spirit of the disclosure. In view of the foregoing, it is intended that the disclosure covers modifications and variations of this disclosure provided they fall within the scope of the following claims and their equivalents.
