Abstract

The present invention relates to a kind of door bell message-leaving machine, comprise doorbell part, recording part, power unit and timing controlled part.The doorbell part mainly comprises music-integrating block and sounding component, the recording part comprises microphone and sound-track engraving apparatus, the direct-current working volts that provide other parts required are provided power unit, the timing controlled part is made up of timing circuit and relay, and the pair of contact of relay is connected in series with recorder power, is used for the work of timing controlled sound-track engraving apparatus, because the control of timing circuit, this answering machine has the characteristics of segmentation recording, thereby can increase the number of times of message, prevents to smear by mistake.

Description

Multi-section recording door bell message-recording device

The present invention relates to a kind of door bell message-leaving machine, but a kind of door bell message-leaving machine of Multitake recording particularly.

Existing doorbell only comprises acoustics (acoustics electronics or machinery) and switch or drive part, and function singleness can't accurately be transmitted various information.For this reason, door bell message-leaving machine arises at the historic moment, and existing door bell message-leaving machine mainly contains two kinds, and a kind of is the magnetic recording formula; Another kind is to be the stored digital formula of carrier with the integrated circuit.The latter is simple in structure, and cost is low, but record length is short, can't satisfy multidigit guest's needs; The former circulation tape transports that adopt are easy to generate blanking bar or mistake and problem such as smear more.

The objective of the invention is to provide a kind of door bell message-leaving machine of sectional recording, it has overcome defectives such as existing answering machine record length is lacked or smear by mistake, has the function of doorbell and answering machine, and is provided with timing control switch.

For achieving the above object, multi-section recording door bell message-recording device of the present invention comprises: doorbell part, recording part, power unit and timing part.Doorbell partly comprises acoustics circuit, amplifying circuit and sounding component; The recording part comprises a microphone and a sound-track engraving apparatus (can adopt common sound-track engraving apparatus); Power unit comprises rectification and mu balanced circuit, and the operating voltage that provides other each several part required is provided; The timing control part branch comprises a timing circuit and a relay, the closure time of timing circuit may command relay, thereby the record length of control sound-track engraving apparatus (such as each recording 1 minute, the common tape of a box can repeatedly be recorded so).When the guest opens visit, he (or she) can press doorbell switch (being generally pushbutton switch) earlier, this moment, doorbell was partly worked, and sounding component produces musical sound, and the prompting owner has the people visiting; If nobody opens the door and replys after pressing doorbell, show that owner is not indoor, this moment, the guest can press the message key, in message key closure, sound-track engraving apparatus is initially located in recording state, and by the peripheral hardware microphone guest's message (voice signal) is noted, because the message time can finish at 1 minute mostly, so timing control part branch cuts off recorder power automatically after 1 minute, if press the message key once more, can leave a message once more (being the segmentation message).The message signal can reproduce by the playback mechanism of sound-track engraving apparatus.

Because adopt said structure, multi-section recording door bell message-recording device of the present invention has following advantage: can many people repeatedly record, mistake can not take place smear; Adopt the common sound-track engraving apparatus device of noting down, integrated cost is low; Automatically cut off recorder power, security is good; Message T.T. is long.

Below in conjunction with accompanying drawing preferred implementation of the present invention is described.

As shown in the figure, this multi-section recording door bell message-recording device comprises: doorbell part, recording part, power unit and timing controlled part.The doorbell part mainly comprises music integrated block IC 2(KD-151) and sounding component (being loudspeaker) Y, its operating voltage is provided by power unit, AN2 is the push button doorbell switch, this switch is located at the position that outdoor visitor easily finds and uses, when pressing this switch AN2, the signal of music integrated block IC 2 outputs amplifies rear drive loudspeaker sounding through triode BG1, thereby realizes common doorbell function.The recording part comprises that the attaching plug of microphone MIC and common sound-track engraving apparatus (not shown) sound-track engraving apparatus is inserted among the jack Z, and microphone MIC plays amplification and matching effect through field effect transistor BG2() link to each other with plug D, this plug can insert the MIC delivery outlet of sound-track engraving apparatus.Power unit comprises that transformer B, rectifier IC4 and voltage stabilizer IC3 are used to provide DC voltage (for example 6 volts).The power supply of sound-track engraving apparatus assigns to control break-make by the contact J_1 of relay J by timing control part, the timing controlled part is mainly by ic chip 1(NE555) come regularly, when pressing message key AN1, this integrated package is triggered and is worked, and makes the J_1 contact be in contact condition, sound-track engraving apparatus work, after the experience schedule time (as 1 minute), the integrated package state changes, and contact J_1 disconnects, and sound-track engraving apparatus quits work.Message key AN1 also is arranged at outdoor, and microphone MIC is contained in the position of the voice signal of being convenient to the outer guest of receiving chamber.

Claims

A kind of segmentation Door bell with recording device answering machine, comprise the doorbell part, recording part and power unit, the doorbell part mainly comprises music-integrating block and sounding component, power unit comprises transformer, rectifier and voltage stabilizer, in order to DC voltage to be provided, the recording part comprises microphone and sound-track engraving apparatus, it is characterized in that also comprising the timing controlled part, this part comprises timing circuit and relay, the pair of contact of relay be connected to the electric main power supply after recorder power is connected in series.
