The present invention provides a game racquet including an integrated circuit capable of supporting a low-voltage energy current. An embodiment of the invention provides a game racquet including one or more enhancements attached or integrated on the racquet frame. These enhancements may include but are not limited to: one or more LEDs, a sound amplification device, and an electromagnetic vibration emitter. In a further embodiment, the game racquet responds electronically to ball impact on at least one of the strings, and subsequently performs and action or actions including but not limited to making a sound or sounds, triggering lights, triggering LEDs, triggering another type of automation on the racquet such as a vibration emitter within the handle. The game racquet frame comprising at least one string channel in the frame head, bridge, or other area, which houses an actuator responds mechanically to a string movement triggering electronic connection.

A vibration dampener for a racket includes a strip formed of elastomeric material having a first end part and a second end part, the strip having a first incision at the first end part and a second incision at the second end part, at least one hooking member having a hollow body having a hole into which the first end part is inserted and a hook formed at one side of the hollow body, wherein said at least one hooking member each is combined with the strip by inserting the first end part of the strip into the hole of the hollow body and pulling the elastomeric band until the strip and the hollow body makes a restraining knot.

A device capable of generating superposed shock waves, which is applied in a racket having a racket frame and having a racket string with warp strings and weft strings mutually woven to compose a string bed, and includes: at least one first main body formed as a hard medium, a lateral wall member is convexly formed at one side or two sides thereof, a first string slot having an opening at a top end is formed at an inner side of the lateral wall member or the center of the two lateral wall members, a recess is formed at the bottom end of the first string slot; and at least one soft medium, disposed in the first string slot and allowing the racket string to be fastened. As such, the shock wave can be returned for being backwardly transferred to increase the striking force for a ball member.

A face of a racket includes a plurality of first longitudinal threads, a plurality of second longitudinal threads, and a plurality of transverse threads. The first longitudinal threads and the second longitudinal threads are arranged alternately from a center of the face toward outside in a width direction of the racket. A material of each first longitudinal thread is different from a material of each second longitudinal thread. A tension of the first longitudinal thread may be different from a tension of the second longitudinal thread. Preferably, a ratio (N1/N2) of a number N1 of the first longitudinal threads to a number N2 of the second longitudinal threads is greater than or equal to 2/8, but less than or equal to 8/2.
