Sports racket providing sound and lighting effects - has radio circuit connected by elastic concussion switch to cause racket to give amplified sound and instant illumination when ball is hit
A circuit substrate (15) is installed inside the handle (1) of the racket and comprises a sound and light circuit (52) and a radio circuit (53). The latter is connected by an elastic concussion switch (56) to cause the racket to give amplified sound and instant illumination whenever the ball is hit by the racket. Every hitting of the ball will be aggregated and displayed by the counter. The switch includes an upright conducting rod on a substrate carrying the electrical circuit, and a hollow conducting spring surrounding the rod. The rod and spring are connected to the electrical circuit so as to form a switch which is activated when the spring contacts the conducting rod upon vibrating. The handle has opposed openings to allow the installation of a light and speaker in the interior of the handle.
