摘要： A tennis racket with a more-responsive string configuration is an apparatus that allows a user to hit a tennis ball with spin and power in a controlled manner. The apparatus includes a closed-shape beam, a throat, an elongated handle, and a plurality of lines. The elongated handle allows the user to firmly grasp the apparatus, and the throat connects the elongated handle to the closed-shape beam. The plurality of lines is tensionably mounted within the closed-shape beam in order to provide the present invention with an elastic contact area for the tennis ball. Each of the plurality of lines includes a first string and a second string, which are positioned along each other for each of the plurality of lines. In addition, a lateral surface of the first string is positioned tangent to a lateral surface of the second string.
