FIG. 1 shows a golf club head according to a generic embodiment of the present invention. Referring toFIG. 1 , thegolf club head 100 comprises a striking plate 110, ashell 120 and apower zone 130, wherein theshell 120 is fabricated with the striking plate 110 to form a main body 102, and thepower zone 130 is formed on the inner wall of theshell 120. There is no set limit on the fabrication of the main body 102 and thepower zone 130. For example, the striking plate 110 may be integrally formed with theshell 120 or independently fabricated and then bonded with theshell 120 by any applicable means. In addition, thepower zone 130 may be integrally formed with theshell 120 or formed after the fabrication of theshell 120. - In the present embodiment, the
power zone 130 is designed to satisfy the following equations: (S/W)=4˜40, and ((d1+d2)/d1)=1.6˜6. In the above equations, S is a distance from a center of the striking plate 110 to an edge of thepower zone 130 along the outer surface, W is a width of thepower zone 130, d1 is a thickness of theshell 120, and d2 is a thickness of thepower zone 130. Fabricating thegolf club head 100 according to the equations can obtain a superior effect of ball controlling and hitting. The distance S may be limited in 120 mm for a more preferable effect of ball controlling and hitting, while there should by no means limit the distance S in the present invention. For example, each of the parameters d1, d2, S, and W may be a constant or a variable due to the requirements of structural design of thegolf club head 100. - Specifically, as shown in
FIG. 1 , thepower zone 130 separates the main body 102 of thegolf club head 100 into afront portion 104 a and aback portion 104 b. When using thegolf club head 100 to hit a golf ball, the striking plate 110 of the main body 102 strikes the golf ball, receives the striking energy, and then a deformation is produced on the main body 102. Due to the isolation of thepower zone 130, the striking energy is restricted in thefront portion 104 a of the main body 102 from theback portion 104 b of the main body 102, and thus the deformation is concentrated in thefront portion 104 a of the main body 102. Therefore, the coefficient of reaction of thegolf club head 100 is enhanced. Furthermore, due to the concentrated and large deformation of thefront portion 104 a of the main body 102, the contact time between the golf ball and the striking plate 110 is prolonged. By which, the effect of ball controlling and hitting is improved. - In the following, the structure of the power zone of the present invention is disclosed in detail by other embodiments. Referring to
