Shake responsive handheld device

Abstract

A shake responsive handheld device is provided. The handheld device comprises a storage unit, a sound output, a motion sensing unit, a motions state determining unit, and a processing unit. The storage unit stores at least one media file configured for reproducing sound of tumbling dice in a dice shaker. The sound output is used for outputting sound. The motion sensing unit is used for detecting a shaking motion imparted to the housing by a user. The motions state determining unit is used for monitoring a shake level of the shaking motion according to signals from the motion sensing unit. When the at least one media file is playing, the processing unit adjusts the sound volume of the sound output unit according to the shake level determined by the motion state determining unit.

1 . A shaking responsive handheld device comprising:
 a storage unit storing at least one media file configured for reproducing sound of tumbling dice in a dice shaker;   a sound output unit configured for outputting sound;   a motion sensing unit capable of detecting a shaking motion imparted to the handheld device by a user;   a motion state determining unit capable of monitoring a shake level of the shaking motion according to signals from the motion sensing unit;   a processing unit, wherein, when the at least one media file is playing, the processing unit adjusts the sound volume of the sound output unit according to the shake level determined by the motion state determining unit.   
   
   
       2 . The shaking responsive handheld device according to  claim 1 , wherein the motion sensing unit is an acceleration sensor. 
   
   
       3 . The shaking responsive handheld device according to  claim 1 , wherein the motion sensing unit is a vibration switch. 
   
   
       4 . The shaking responsive handheld device according to  claim 3 , wherein the shake level is determined by detecting the number of times of state changing of the vibration switch per unit time period. 
   
   
       5 . The shaking responsive handheld device according to  claim 3 , wherein the vibration switch comprises a coil spring, a first contact terminal, and a second contact terminal, the coil spring is electrically coupled to the first contact terminal and is capable of deflecting and contacting the second contact terminal during the shaking of the handheld device. 
   
   
       6 . The shaking responsive handheld device according to  claim 3 , wherein the coil spring deflects when the handheld device is shaken in a predetermined direction. 
   
   
       7 . The shaking responsive handheld device according to  claim 3 , wherein the vibration switch comprises a chamber, a movable member with two spring ends, and two contact terminals, the moveable member is received in the chamber, the two spring ends contact with the first contact terminal and the second contact terminal respectively, at least one of the spring ends is capable of disengaging one of the two contact terminals during the shaking of the handheld device. 
   
   
       8 . The shaking responsive handheld device according to  claim 7 , wherein the movable member comprises an inertial weight and two coil springs, the two coil springs are attached to two ends of the inertial weight respectively. 
   
   
       9 . The shaking responsive handheld device according to  claim 1 , wherein the storage unit further stores a fade-out media file for reproducing a sound effect of tumbling dice that roll inertially in a dice shaker after the dice shaker has stopped shaking, when having determined that the shaking motion ceases, the processing unit plays the fade-out media file. 
   
   
       10 . The shaking responsive handheld device according to  claim 9 , wherein the storage unit further stores a simulation program for generating a game result after the fade-out media file finishes playing.
