Claims

[Claims for Utility Model Registration] (1) In a racket in which the frame is composed of an annular head portion that stretches a string and a shaft portion extending from the head portion and including a grip portion, vibration of the frame or the string is detected. 1. A racket comprising: a sensor that generates vibrations; and a speaker that emits a sound corresponding to the vibration of the frame or gut based on a signal from the sensor. (2) The racket according to claim (1), wherein the sensor is fixed to the frame or the gut, and the speaker is arranged on the frame. (3) The racket according to claim (1), wherein the sensor is fixed to the frame or the gut, and the speaker is located at a separate location away from the frame. (4) In a racket in which the frame is composed of an annular head section on which a string is stretched, and a shaft section extending from the head section and provided with a grip section, there is provided a sensor for detecting vibration of the frame or the string, and a sensor for detecting vibrations from the sensor. A racket characterized by comprising a speaker that outputs sound from a predetermined sound source based on a signal. (5) The racket according to claim (4), wherein the sensor is fixed to the frame or the gut, and the speaker is arranged on the frame. (6) The racket according to claim (4), wherein the sensor is fixed to the frame or the gut, and the speaker is located at a separate location away from the frame.
