Patent ID: 8588946

Claim:
A portable device having a function for providing an acoustic source information, comprising: a characteristic code extractor configured to receive an acoustic source to divide the acoustic source into an audio signal with an audio frequency band and a signal with a supersonic frequency band, the characteristic code extractor extracting a characteristic code of the audio signal with the audio frequency band from the signal with the supersonic frequency band; and a controller configured to transmit the characteristic code to an acoustic information server, and configured to output the acoustic source information corresponding to the characteristic code that is provided from the acoustic information server, wherein the acoustic source includes the audio signal with the audio frequency band and the signal with the supersonic frequency band having the characteristic code used for distinguishing one audio signal with the audio frequency band from another audio signal with the audio frequency band, wherein the characteristic code extractor includes: a high pass filter for separating the signal with the supersonic frequency band from the acoustic source; and a binary code extractor for extracting the characteristic code having a binary logic value from the signal with the supersonic frequency band, wherein the binary code extractor includes a transistor (Q) having an emitter, a base, and a collector node and a resistor (R) connected between the collector node of the transistor (Q) and a power source (Vcc).
