| 摘要 |
The present invention relates to an ear level electronic device comprising a housing that is adapted to be worn behind the ear, in the ear, or in the ear canal, and to enclose a music synthesizer for generation of an electrical signal representing music and an output transducer for conversion of the electrical signal into sound. In the device, sound generators are controlled by pseudo-random number generators generating sequences of self-similar numbers whereby music is synthesized that is surprisingly relaxing and comfortable to listen to. Further, a music sequence generated by such a number generator is extremely long so that a person listening to the music does not have a perception of being listening to repeated music sequences.
