Sound-emitting wallet

Abstract

A sound emitting wallet comprises a sound module installed in a wallet. The sound module comprises a switch, an activation tab attached to part of the wallet and to the switch, a sound controller, a sound emitter, a battery, and optionally a microphone. In some embodiments, sound is emitted when part of the wallet is unfolded. Sound may optionally be emitted when a pocket in the wallet is opened. Different sounds may optionally be emitted for opening and closing parts of a wallet. Sounds to be emitted may be predetermined at the time the wallet is manufactured or may be loaded into a sound module and saved in a memory device. In some embodiments, a sound module may be adapted to record sound, retain a representation of the sound in a memory device, and later emit the sound.

1 . A sound emitting wallet, comprising:
 a wallet having a compartment, a first fold boundary, and a second fold boundary; and   a first sound module installed in said compartment, said first sound module comprising:
 a means of activation comprising a switch, wherein said switch comprises a first state and a second state; 
 a sound controller electrically connected to said means of activation; and 
 a sound emitter electrically connected to said sound controller, 
   wherein a relative motion between said first fold boundary and said second fold boundary causes said switch to change from said first state to said second state and causes said sound emitter to emit sound.   
   
   
       2 . The sound emitting wallet of  claim 1 , wherein said first sound module further comprises a memory device for saving a plurality of representations of sounds to be emitted. 
   
   
       3 . The sound emitting wallet of  claim 2 , further comprising at least two electrical terminals electrically connected to said sound controller, wherein said sound controller is adapted to receive through said electrical terminals a representation of sound to be emitted by said first sound module. 
   
   
       4 . The sound emitting wallet of  claim 3 , wherein said terminals are adapted to be compatible with an input/output interface on a personal computer. 
   
   
       5 . The sound emitting wallet of  claim 2 , wherein said sound controller is adapted to randomly select a representation of a sound to be emitted from among a plurality of representations of sounds saved in said memory device. 
   
   
       6 . The sound emitting wallet of  claim 2 , wherein said sound controller is adapted to sequentially select a representation of a sound to be emitted from a plurality of representations of sounds saved in said memory device. 
   
   
       7 . The sound emitting wallet of  claim 2 , further comprising:
 said wallet further comprising a third folding boundary and a fourth folding boundary; and   a second sound module adapted to emit sound when a fold is formed between said third folding boundary and said fourth folding boundary,   wherein said first sound module and said second sound module do not emit the same sound.   
   
   
       8 . The sound emitting wallet of  claim 2 , further comprising:
 a pocket having a flap for closing said pocket; and   a second sound module adapted to emit sound when said pocket is opened.   
   
   
       9 . The sound emitting wallet of  claim 8 , wherein said first sound module emits a sound for identifying said compartment and said second module emits a different sound for identifying said pocket. 
   
   
       10 . The sound emitting wallet of  claim 8 , wherein said second module emits a sound corresponding to an amount of a transit fare. 
   
   
       11 . The sound emitting wallet of  claim 8 , wherein at least one of said sound modules emits an alarm when a part of the wallet is opened. 
   
   
       12 . The sound emitting wallet of  claim 2 , wherein said sound module further comprises a microphone electrically connected to said sound controller, and said microphone and said sound controller cooperate to record a sound to be emitted and save the sound to be emitted in said memory. 
   
   
       13 . The sound emitting wallet of  claim 2 , wherein said sound module is removably attached to the wallet. 
   
   
       14 . The sound emitting wallet of  claim 2 , wherein said memory device is removably attached to the sound module and said memory device is adapted for connection to an input/output port on a personal computer. 
   
   
       15 . The sound emitting wallet of  claim 2 , wherein the wallet has a visual appearance related to a subject, said visual theme comprising a selected size of the wallet, a selected shape of the wallet, and a selected color scheme for the wallet, and the wallet emits sound related to the same subject. 
   
   
       16 . A sound emitting wallet, comprising:
 a wallet able to be folded and unfolded along a first fold and a compartment accessible by unfolding said first fold; and   a first sound module adapted to emit sound when said first fold is unfolded.   
   
   
       17 . The sound emitting wallet of  claim 16 , said sound module further comprising means for recording sound. 
   
   
       18 . The sound emitting wallet of  claim 16 , further comprising a pocket having a flap secured with a fastener. 
   
   
       19 . The sound emitting wallet of  claim 18 , further comprising a second sound module adapted to emit sound when said pocket is opened. 
   
   
       20 . The sound emitting wallet of  claim 16 , further comprising:
 said wallet further able to be folded and unfolded along a second fold, wherein said compartment is accessible by unfolding said first fold and said second fold; and   a second sound module adapted to emit sound when said second fold is unfolded.
