Abstract

A digital audio recording apparatus having call logging function is provided. The digital audio recording apparatus is connected to a telephone set as well as an external line for automatic detecting/capturing call log information and recording audio signals therewith. Furthermore, digitized audio signals are saved in a portable storage media, e.g. a memory card, via the digital audio recording apparatus. Larger capacity and higher flexibility of data storage are thus provided, and the filing of call logs is properly managed as dialogue time is clocked.

Claims

1. A digital audio recording apparatus, comprising a recording apparatus and a call detecting module coupling to an external line and a telephone set, the call detecting module comprising:

a detecting/capturing circuit, detecting and capturing incoming/outgoing call information from said external line and said telephone set, and transmitting a activating signal and said captured incoming/outgoing call information to said recording apparatus according to detected result;

said recording apparatus comprising;

a portable storage media;

a timing circuit, wherein a timing function is triggered by the detecting activating signal, and a call log is generated; and

a microcontroller, electrically coupling to said portable storage media and said timing circuit, receiving call log and incoming/outgoing call information, and saving said call log information and said incoming/outgoing call information to the portable storage media in an archival format.

2. The digital audio recording apparatus as recited in claim 1, wherein said incoming/outgoing call information comprises a telephone number and an incoming/outgoing direction.

3. The digital audio recording apparatus as recited in claim 1, wherein said call log comprises a dialogue start/end time, a call length and a date.

4. The digital audio recording apparatus as recited in claim 1, wherein said portable storage media is one selected from the group consisting of a silicon storage media, an optical storage media, and a magnetic storage media.

5. The digital audio recording apparatus as recited in claim 1, wherein said call detecting module and said recording apparatus further comprise a first extended interface and a second extended interface respectively to transmit a user'"'"'s audio signal transmitted by the telephone set or the external line, said detecting activating signal, said incoming/outgoing call information and an operative instruction given by said microcontroller.

6. The digital audio recording apparatus as recited in claim 5, wherein one of a cable transmission method and a wireless transmission method is performed between said first extended interface and said second extended interface.

7. The digital audio recording apparatus as recited in claim 5, wherein said call detecting module further comprises:

a telephone interface, coupling to said telephone set, to transmit said user'"'"'s audio signal in analog form and an outgoing call information;

an external line interface, coupling to said external line and electrically coupling to said telephone interface, to transmit said user'"'"'s audio signal in analog form and an incoming call information; and

an audio converting circuit, electrically coupling to said telephone interface, said external line interface, said detecting/capturing circuit and said first extended interface, receiving said incoming/outgoing call information in analog form and said user'"'"'s audio signal, and transmitting said incoming/outgoing call information to said digital audio recording apparatus via said first extended interface for digitization.

8. The digital audio recording apparatus as recited in claim 1, wherein said digital audio recording apparatus further comprises a computer transmission interface, which is electrically coupled to said microcontroller and said portable storage media, and communicates with an external computing system or an external storage media, to storage said information in said external computing system or said storage media.

9. The digital audio recording apparatus as recited in claim 5, wherein said recording apparatus further comprises:

an audio playing circuit, to play said user'"'"'s audio signal stored in the portable storage media;

an audio input interface, electrically coupling to said microcontroller and said second extended interface, to directly receiving an analog audio signal inputting from the external line; and

an analog-to-digital converting circuit (ADC), electrically coupling to said microcontroller, said audio playing circuit and said audio input interface.
