Abstract

A shake responsive media player is provided. The media player comprises a vibration switch that changes its state between an electrically open state and an electrically closed state during the media player is shaken. The media player also comprises a storage unit, a motion state determining unit, a media file determining unit, and a processing unit. The storage unit stores a plurality of media files and a table that defines relationships between shaking levels and the sampling rates of the at least one group of media files. The motion state determining unit determines a duration of the shaking of the media player and the times of state changing of the vibration switch according to signals from the vibration switch and determines a shaking level according to the duration of the shaking of the media player and the times of state changing of the vibration switch.

Claims

1. A shake responsive media player comprising:

a vibration switch changing its state between an electrically open state and an electrically closed state during a shaking of the media player;

a storage unit storing at least one group of media files associated with each other having the same contents and different sampling rates and a table defining a relationship between shaking levels of the shaking of the media player and the sampling rates of the at least one group of media files, the shaking levels indicating how strongly the media player is being shaken;

a motion state determining unit determining the number of times of state changing of the vibration switch in a unit time period to monitor the shaking levels of the shaking of the media player according to signals from the vibration switch;

a media file determining unit, wherein when a first media file of the at least one group of media files is playing, the media file determining unit determines a second media file associated with the first media file, the second media file having a sampling rate corresponding to the shaking level determined by the motion state determining unit according to the table; and

a processing unit playing the second media file until the shaking level determined by the motion state determining unit changes;

wherein the vibration switch comprises a chamber, a movable member, and two contact terminals, the moveable member is received in the chamber and comprises an inertial weight and two coil springs, the two coil springs contact the first contact terminal and the second contact terminal respectively, and the two coil springs are respectively attached to opposite sides of the inertial weight, allowing the inertial weight to compress one of the two coil springs and pull the other one of the two coil springs, thereby enabling at least one of the two coil springs to disengage from the corresponding one of the two contact terminals during the shaking of the media player, which changes the motion sensing unit between an electrically closed state and an electrically open state.
