Description

Computer learning unit with leaving message

But the utility model relates to a kind of automatic record message, answer calls and the recording playback voice computer message learning machine for people's study.

The early development education of current Chinese children become major issue people that the heads of a family generally pay attention to look forward to having more more convenient than recorder, be more suitable for the instrument that children carry out phonetic study.In addition, raising day by day along with people's living standard, telephone penetration rate rapidly increases, especially in modern commodity economy, telephonic communication has become people's work, indispensable liaison method in the life, but common telephony functions is single, when the user not the time can not write down message automatically, answer calls, so the patented technology of a kind of " Telephone volume compression or expansion arrangement " by name has been announced on the utility model patent communique on August 18th, 93, it can inform the other side to owner's message automatically, and can record the other side's conversation down, it is by the phone ringing testing circuit, monostable automatic connection circuit, the message sound circuit, the number of times display circuit of calling, the outer recording circuit that is connected with recorder is formed.This " Telephone volume compression or expansion arrangement " is though solved the automatic message answering of plain old telephone, but its message can not forever be preserved, and simultaneously because its use must connect machine with recorder, so entire mechanism is huge, use is subjected to constraint, and itself can not be used as learning machine.

The utility model provide a kind of easy to use, fidelity is high, power consumption is few, long service life, the small and exquisite computer message learning machine of volume, this function learns a language for children easily, can carry out phone automatic-answering back device message, phone is manually recorded, can also carry out family's message, recorded content can forever be preserved.

The utility model is achieved in that and removes casing, microphone, phone dislodging machine circuit, outside the bell signal detection shaping circuit, it also has an amplifier, loud speaker, a function logic control circuit, a voice storage playback circuitry, the function logic control circuit sends signal and blocks microphone during energized, this machine enters automatic mode, telephone call signal is through the bell signal detection shaping circuit, make telephone wire be in off hook state through phone dislodging machine circuit again, by the function logic control circuit signal is sent into the voice storage playback circuitry simultaneously, this voice storage playback circuitry enters tone playing state, voice signal is sent into the other side's receiver by the function logic control circuit, when sending words to finish, the voice storage playback circuitry is exported a signal to the function logic control circuit, this moment, the function logic control circuit made the voice storage playback circuitry be in the recording operating state, the other side's voice signal is sent into the voice storage playback circuitry through the dislodging machine circuit and is carried out record, stipulated time uses up the back recording and stops, when the function logic control circuit allows microphone work, bell signal detection shaping circuit locking, signal is sent into the voice storage playback circuitry and record by the function logic control circuit, playback, quit work, if need carry out record this moment to message, can make the dislodging machine circuit be in off hook state by hand switch.

The function logic control circuit is by four triggers, six console switchs and some not circuits are formed, wherein the 5th switch is " mode " selector switch, first switch is a functional select switch, when the mode selector switch is selected " family ", forbid ring detecting circuit work, allow microphone and other switch to carry out " record ", " playback ", " stop " operation, at this moment, if functional switch is selected " message " position, then touch " record " button, register lamp is bright, and the content of required message is by microphone typing chip, heavily by " record " button, then the content that writes down of back will cover the content that writes down previously after pressing " stopping " button.Press " playback " key, then the content of record is broadcasted by loudspeaker, stop automatically then.When functional switch is selected " study " position, " stop " button and play time-out effect in the recording playback work, that is: if " record " operation, then press behind " stopping " key again content that operation " record " key write down and then the content of front deposit rather than the content of covering front.When carrying out " playback " operation, repeat automatically the intact back of the content play of storage, when the mode selector switch is selected " phone ", functional switch need be chosen in " message " position, and at this moment, this machine enters automatic telephone answering, guest's operating state of leaving a message, and forbid microphone and other operating knob work.What the voice storage playback circuitry adopted is direct modeling signal Storage Techniques chip I SD series, the function logic control circuit then is that the control according to this family chip requires and the function setting of this machine designs, phone dislodging machine circuit is by an one-way SCR, a triode and a diode are formed, the method of controlling pole tension that is higher than this circuit employing moment cathode voltage realizes the shutoff to one-way SCR, " off-hook " and on-hook are finished by one-way SCR, and the bell signal detection shaping circuit is by a voltage-stabiliser tube, two electric capacity, two resistance, two diodes and two not gates are formed.When the ring request, voltage-stabiliser tube is breakdown to second electric capacity charging, when its charging potential is higher than the threshold voltage of first not gate, two not gates all overturn, thereby trigger the one-way SCR in the phone dislodging machine circuit, after controllable silicon triggers, voltage-stabiliser tube changes cut-off state over to, at this moment, capacitor discharge, entire circuit restPoses.

For making the utility model power consumption minimum, all chips all adopt the CMOS chip, and non-gate ic adopts CD40106 or CD4069.

The utility model is multiple functional, not only solved common telephony functions single can not automatic-answering back device, technical problem such as message, also need not tape, easy to operate language learner for children provide a kind of and since this machine mainly adopt in large scale integrated circuit, so fault is few, owing to all adopt the CMOS chip, make the complete machine quiescent dissipation little, and recorded content can forever preserve, under the situation of no any power source to 0.9mA, can keep 100 years, it writes down access times repeatedly and can reach 10 in addition ⁶More than inferior, this machine circuit is simple, device is few, cost is low.

Below in conjunction with embodiment the utility model is described in detail.
