Display device of brown ball

Abstract

An improved display device of brown ball comprises: lower body, supporting ring, rotary member and upper body, wherein, lower body has an emitter on the bottom, the emitter has inductive member, emit member, battery and switch member, and further comprises a receive member, the receiver member has rectangular contour and has signal divert member, battery and switch member therein and has display screen thereon. The receive member can be fixed to a band to be convenient for user wear it on the wrist, user rotate the brown ball with another hand, the induce member of emitter induces and measures the rotate speed of brown ball, and the rotate speed be converted into sign by electrical member, and be emitted out with a prearranged frequency by emit member. The sign will be received by receive member and be converted into rotate speed by convert member to display the rotate speed of the brown ball on the display screen.

1 . An improved rotate speed display device of brown ball comprising: lower body, supporting ring, rotary member and upper body, wherein, 
 said lower body is generally half-spherical and defines an encasement therein and has an open thereon;    said supporting ring disposed in inertia of top of said lower body;    said upper body is also generally half-spherical and defines an encasement therein and has an open thereon, fixed on the top of lower body and has an open thereon;    said rotary member is generally spherical and disposed in the said upper and lower body, has a latitude axis and pivoted on said supporting ring by two ends of said axis;    wherein,    lower body has a emitter on the bottom, sand emitter has induce member, emit member, battery and switch member therein and has display screen thereon; user rotates the brown ball with hand, the induce member of emitter induces and measures the rotate speed of brown ball, and the rotate speed be converted into sign by electrical member, and be emit with a prearranged frequency by emit member, the sign will be received by receive member and be converted into rotate speed by convert member to display the rotate speed of the brown ball on the display screen.    
     
     
         2 . The improved rotate speed display device of brown ball according to  claim 1 , wherein said lower body defines a sunk encasement on the bottom for encasing electrical member such as emitter, a cover enclose the encasement.  
     
     
         3 . The improved rotate speed display device of brown ball according to  claim 1  or  2 , wherein said receive device can be fixed to a band to be convenient for user wearing on the wrist.
