Description

Recording device of digital -phone utilizing computer and method

The present invention relates to a digital telephone recording apparatus using a computer, wherein the digital recording and reproducing repeater of the present invention is added between a telephone and a handset, and the digital recording and reproducing repeater excites the guide sound of the handset to provide the sound card of the computer. It is a device that can be recorded in the necessary index because it is stored in digital state and stored by dividing it into main words.

In general, a recording technique using a telephone includes a pickup coil 2 placed near the handset of the telephone 1, a general recorder 3 for recording an input signal from the pickup coil 2, and It consists of a recording tape storage part (4).

In this case, the telephone line 5 connected to the telephone 1 is a telephone line coming from a telephone company or from an in-house telephone distributor for a telephone call of the telephone 1. The telephone line 5 carries a sound wave signal converted into an electrical signal, and the sound signal of the telephone call counterpart and the telephone call is mixed with each other and converted into a single electrical signal.

In addition, the telephone 1 is a device that is connected to the telephone line 5 and used by the user for a telephone call. The signal coming through the telephone line is converted into an electric signal by the sound wave signal of the telephone call counterpart. This function must be converted into a sound wave signal that can be recognized by the telephone caller, and this function must be processed by the telephone, and the sound wave signal generated by the telephone caller must be converted into an electrical signal that can be transmitted from the telephone line. Process on In this way, the phone converts the sound wave signals of the two cases into electrical signals, such as the sound wave signals generated by the other party and the sound wave signals generated by the telephone call. . The telephones include general telephones and key phones used for office use.

The pick-up coil 2 collects the telephone call sound from the telephone receiver and transmits it to the cassette recorder in the form of an electrical signal so that the telephone call 1 can store the contents of the telephone call.

Fig. 2 is a technical principle of the pick-up coil 2, which is a speaker (generally a ringing plate 12, a permanent magnet 13, and a voice) which is used in the handset 11 of the telephone 1 to generate an acoustic signal as an electric signal. Since the magnetic field 15 is formed around the voice coil 14 of the coil 14) according to the magnitude of the sound wave signal, the pickup coil 2 approaches the handset 11 so that the strength of the magnetic field can be measured. By doing so, the phone call can be picked up.

Cassette tape recorder (3) is a device that can store the contents of the call with the other party using a telephone, such as a commercial cassette tape recorder used in the market, a cassette tape is required as a medium for storing the contents of the telephone call .

As described above, the operation principle of the recording of the telephone call contents using the cassette tape recorder is largely performed in the recording apparatus consisting of the telephone line 5, the telephone 1, the pick-up coil 2, and the cassette tape recorder 3. The signal coming into the telephone line 5 from the telephone splitter is a signal obtained by converting the sound wave signal of the telephone caller and the sound wave signal of the telephone call counterpart into an electrical signal and combining the two electrical signals into one electrical signal. Amplified to allow handset. In this case, the handset attached to the telephone is provided with a pick-up coil 2 and delivered to the cassette tape recorder 3. Electrical signals provided to the cassette tape recorder 3 are stored in a cassette tape which is a storage medium.

However, this method requires a cassette tape, which is a storage medium for the contents of a telephone call, when recording, which is inconvenient to transfer and transfer the cassette tape in the form of a type.

In addition, when using cassette tape as a storage medium, the recorded telephone call contents may be erased when magnetic material is around due to the nature of the cassette tape itself, and the function of cassette tape may be lost due to moisture. Difficulties follow

In addition, since the cassette tape is bulky, when storing the contents of a telephone call over a long period of time, a large number of cassette tapes are required, and a large amount of space is required on the recording tape to store them.

In addition, the cassette tape stores the contents of a telephone call in order according to time, and the playback position must be adjusted to the desired position by fast forwarding or rewinding the cassette tape in order to search for an arbitrary position. It takes a lot of time and effort.

In addition, when making a copy using cassette tape, noise is mixed during copying, and playing, rewinding, or fast-forwarding the cassette tape shortens the life of the cassette tape. In addition, since the cassette tape is used as a storage medium, a large maintenance cost is required due to the cost of preventing or retrieving the aging of the cassette tape.

In addition, the limit of storing the telephone call on the cassette tape is that the contents of the telephone call of about one hour per cassette tape can be stored. This storage capacity greatly increases the number of cassette tapes required to store phone calls over a long period of time, and it is cumbersome to find the phone calls required by hand when searching. There are many disadvantages, including concerns.

An object of the present invention is to store the contents of the telephone call on the computer and to automatically search using the contents previously input, etc., and to easily manage by storing the contents of the call for a certain period of time on a general CD-ROM and the like.

To this end, the present invention includes a digital recording and playback repeater between the telephone body and the telephone handset connecting line, and stores a digital conversion signal through a sound card to a computer or converts an analog signal to a digital signal through a repeater. After the memory is stored in the auxiliary memory device, it is searched through a separate search means and outputted to the recording content output unit.
