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.
