This present invention relates to a racket. More particularly, this invention relates to a racket having means capable of outputting a melody to stimulate a user's interest moreover, a melody generator is formed to have a shockproof structure.

BACKGROUND ART

Conventionally, a racket comprises a racket handle extending to a lower part of a frame that forms an external shape and a reactionary portion formed inside this frame. This reactionary portion makes a ball or a plaything fly away. The reactionary portion is formed of latticed guts (racket strings) winding on the frame. For example, a racket, a tennis racket receiving a strong hitting force a tennis racket is made of a hard frame and thick guts to receive a strong hitting force.

Like a badminton racket hitting a shuttlecock a racket receiving a weak hitting force does not need to be made of a hard frame and thick guts. So this racket is made of a thinner frame and guts than those of the tennis racket.

A tennis racket of the present invention includes a melody sensor 44 for outputting a melody in accordance with vibration when a ball is being struck. Referring to Fig.6, the racket including the melody sensor has a slot 38 on the higher part of a racket handle 36 extending from a frame 33 to a supporting body 34; and a speaker 40 in the slot 38.

The speaker 40 is connected to the melody sensor 44 mounted to the lower part of the frame 33 by a lead line

42 burying through the supporting body 34 electrically.

The melody sensor 44 is mounted to the slot 46 on the frame 33 and is connected to the lead line 42 electrically. This melody sensor 44 does not operate below a predetermined level of vibration, since a vibration preventing circuit 48 absorbs vibration under the predetermined level and vibration is not transmitted to the melody sensor 44.

Referring now to Fig.7 depicting a conventional second embodiment, a tennis racket having a melody sensor includes a speaker 40' and a melody sensor 44' respectively mounted on slots 38', 46' formed on an upper part of a racket handle 30'

The above-mentioned racket having a melody sensor makes a user know whether a ball is being struck accurately. When he strikes the ball accurately and the powerful hitting force acts on the racket, vibration of the guts is conducted to the melody sensors 44, 44' through the frame 32. The melody sensors 44, 44' comprising a general circuit output a melody signal to the speakers 40, 40'. The speakers 40, 40' being connected to the melody sensors 44, 44' electrically outputs a melody signal as a melody.

However, general rackets have a slot for establishing a melody output circuit on part connecting of a frame with a racket handle, and a racket frame damages easily because of structural vulnerability. A

lead line is buried in a pathway of the supporting body connecting to the racket handle. Not only having a difficulty in manufacture but also having a defect of an absence of a shock absorber for protecting the melody sensor from a shock when a ball is being struck.
