Abstract

The utility model relates to a voice recorder for online telephone, comprising receiving input end (1, 2), a transformer L and a voice-recording output end (3, 4). The utility model is characterized in that the receiving input end (1, 2) is connected with a capacitance C and a primary coil of the transformer L; one end of the secondary coil of the transformer L is connected with one end of a resistance R1 and the voice-recording output end (3) while the other end of the secondary coil of the transformer L is connected with the other end of a resistance R2; the other end of the resistance R1 and the resistance R2 are connected with the voice-recording output end (4). The utility model has the advantages of simple structure, convenience for voice-recording, ability to record dual-way voice signals during calling and ability to switch to the voice recorder for recording.

Description

Online Recorder of telephone

Technical field

The utility model relates to a kind of recording switching device, relates to a kind of bi-directional speech signal of telephone relation process can the intercepting specifically, and is transferred to the device on the sound pick-up outfit.

Background technology

At present, when utilizing telephone relation,, usually be that recorder is opened in order to record, and as far as possible with the close telephone set of the pick-up head of recorder, with the recording effect of obtaining.Yet, both wasted time and energy like this, can not two-wayly record again, recording effect is bad.In a word, also do not have so far and the bi-directional speech signal of telephone relation process can be intercepted, and be transferred to device on the sound pick-up outfit.

Summary of the invention

The purpose of this utility model is to provide a kind of and the bi-directional speech signal of telephone relation process can be intercepted, and is transferred to the online Recorder of telephone on the sound pick-up outfit, to remedy the deficiencies in the prior art.

The purpose of this utility model is to realize like this, it comprises reception input (1,2), transformer L and recording output (3,4), it is characterized in that: receive the primary coil that is serially connected with capacitor C and transformer L on the input (1,2), one end of transformer L secondary coil is connected with recording output (3) with an end of resistance R 1, the other end of transformer L secondary coil is connected with an end of resistance R 2, and the other end of resistance R 1 and resistance R 2 is connected with recording output (4).

It is characterized in that: described reception input (1,2) is parallel with two telephony interfaces (5).

The utility model compared with prior art, it is simple in structure, for recording provides convenience, the bi-directional speech signal of telephone relation process can be intercepted, and can be transferred on the sound pick-up outfit and record.

Among the figure: 1, receive input, 2, receive input, 3, the recording output, 4, the recording output, 5, telephony interface, 6, recorder, 7, telephone set, 8, public telephone network.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified:

Referring to accompanying drawing 1, it comprises reception input 1,2, transformer L and recording output 3,4 the utility model, be serially connected with the primary coil of capacitor C and transformer L on the described reception input 1,2, one end of transformer L secondary coil is connected with recording output 3 with an end of resistance R 1, the other end of transformer L secondary coil is connected with an end of resistance R 2, and the other end of resistance R 1 and resistance R 2 is connected with recording output 4.Wherein: transformer L inductance value is 800mh, and C is a metal film electric capacity, and capacitance is 100pf, and resistance R 1, R2 are 1K Ω.

Utilize reception input 1,2 the bi-directional speech signal of telephone relation process to be intercepted, and by transformer L be coupled to the recording output 3,4, be linked on the recording access of recorder by recording output 3,4 again, or be linked on the recording access of computer, or be linked on the recording access of other sound pick-up outfit that can record.More convenient for the utility model is used, can be on described reception input 1,2 two telephony interfaces 5 in parallel, described telephony interface 5 is a telephone socket.Utilize telephony interface 5 directly to be connected with telephone set 7, public telephone network 8 easily, recording output 3,4 is linked on the recording access of recorder, promptly can record easily (as shown in Figure 2).
