Description

Voice memory beeper

The utility model relates to a kind of beeper of telecommunications context.

At present, at modal beeper (BB machine) on the market, mainly by reception, decoding, electric bell and show that four parts form, its displaying contents divides digital and two kinds of literal, and can not exceed 20 individual characters at most.This beeper not only information minimum, the scope of application is narrow, and complex manufacturing, price height, unsuitable popularization and application.

The purpose of this utility model is intended to overcome the deficiency of above-mentioned BB machine, provides a kind of and has contained much information, and the scope of application is wide, and makes easily cheap language memory-type beeper.

The purpose of this utility model is to realize like this: the movement in housing is made up of reception, decoding, language memory, power amplification, five parts of electric bell (jingle bell), each several part all adopts integrated circuit and peripheral circuit to constitute, its receiving unit adopts monolithic frequency modulation integrated circuit, and the language memory section adopts ultra-large CMOS language processor and dynamic memor.

Monolithic frequency modulation integrated circuit is TDA7021T.

Ultra-large CMOS language processor is language integrated circuit VTVOO1B, and dynamic memor is DRAM41256.

The utility model is compared with existing BB machine, has reduced the display part, has set up the language memory section, and its outward appearance is similar.Because the information that transmits is directly used language, so except that the purposes with BB machine, amount of information increases, expression way is more directly perceived, can repeat arbitrarily information is told, and the words and phrases capacity reaches the language message in eight seconds, can say unnecessary 30 individual characters.Because it is the each several part circuit adopts integrated package, simple in structure again so components and parts are few, to make easily, cost is low, very easily popularization and application.

Below in conjunction with accompanying drawing the utility model embodiment is elaborated:

Fig. 1 is a circuit block diagram of the present utility model.

Fig. 2 is the circuit theory diagrams of Fig. 1 square frame

Fig. 3 is a contour structures front view of the present utility model.

Fig. 4 is the right side view of Fig. 3.

Embodiment: referring to Fig. 1-Fig. 4.The entire circuit that comprises reception, decoding, language, memory, power amplifier, jingle bell part is housed in housing 1 makes core body.Its receiving unit is made of the peripheral high-frequency circuit of monolithic frequency modulation integrated circuit (IC) 4 and received signal, and the working power of integrated circuit (IC) 4 is supplied with by the battery E3 with battery E2 charging; The decoder of decoded portion adopts CMOS large-scale digital ic IC5; The language memory section is by language processor IC1 and dynamic memor IC2 and removing (also being recording) key K1, playback button K2, resistance R 9, R10, capacitor C 8, and triode BG1, BG2, the peripheral circuit that LED 1, LED2 etc. constitute is formed; At 13 pin (D/A switch output) of integrated circuit (IC) 1 through resistance R 7, R6 and capacitor C 6 Filtering Processing be connected to ic chip 3 works done discharges road, the jingle bell part is made up of integrated circuit (IC) 6, triode BG4, loud speaker Y and change over switch K3 with playback, idle function; The working power of integrated circuit (IC) 1, IC2, IC5 is by battery E1(6V) supply with.Its K switch 3, removing, playback button K1, K2 and LED 1, LED2 are installed in housing 1 upper end, loud speaker Y, battery E2 are installed in the front of housing 1, two interior lines, the one termination battery E2 that on housing 1, has twin-core shielding conductor, this shielding conductor, the other end is connected to the plug CT1 that inserts jack CK1, jack CK1 meets battery E3, battery E3 is contained on the cuff link 2, and screen meets antenna TX1.Battery E1 is equipped with in the housing inboard, and the back side also is provided with belt clamp 4.(this transmitter is to launch twice code signal earlier to this beeper when in a single day integrated circuit (IC) 4 receives the code signal of sending from transmitter, launch language message again) with decoder IC5 self the coding identical, 17 pin (control end) of IC5 are high potential output, and hold the 4th pin by the recording that triode BG3 goes to trigger IC1, the language message that received by IC4 this moment just is stored among the container IC2 by language integrated circuit (IC) 1, meanwhile LED 1, LED2 is all bright, make 8 pin (drive end) of IC1 be electronegative potential, triggering bell circuit IC6 makes loud speaker send the prompting sound of being notified from a phone call, jingle bell stops after about eight seconds, LED 1 extinguishes, LED 2 is still lighted always, only otherwise meet clear key K1(meanwhile, amplify through IC3 after this) by D/A switch output 13 pin of IC1.Can use playback button K2 that paging information is emitted at any time.

The technical indicator of this beeper: be 8 seconds memory time, also can transfer to 16 seconds, and sensitivity is 10 μ v/m, prompting electric bell sound loudness＞80db(8 second), receive frequency stuck-at-10MhZ can hold 4,000,000 extension sets in a paging system.

The use of this beeper: in the housing of earlier battery being packed into, plug CT1 is inserted in the socket CK1, again K switch 3 is placed holding state, in case there is the people to notify from a phone call, just can hear telephone bell, simultaneously LED 1, LED2 are all bright, and diode (LED) 1 extinguishes after about eight seconds, paging information this moment this machine of typing fully.At this moment only need K switch 3 is placed tone playing state, press playback button K2 again, can hear the content of call; Also K switch 3 can be placed tone playing state at ordinary times, not have the prompting sound of electric bell when just being notified from a phone call, but content is once notified from a phone call in earlier automatic broadcast; If will remove internal memory, need only be by a clear key K1, LED 2 just extinguishes.Because clear key K1 is a clear key is again the record button switch, therefore can only click at every turn, if press K1 twice continuously, memory circuit just enters recording state, and power consumption is increased severely, after LED1 such as at this moment having only to go out, when treating that noise stops, pressing the K2 key again, hear the sound of " toot " after, press the K1 key again, just can restore to holding state.If unmanned by machine when notifying from a phone call,, also represent to be notified from a phone call as long as see LED 2 light yellow always.

Each integrated circuit of this beeper: IC1 is that VTV001B(also can change peripheral circuit slightly, use VMOS101, HHY40, replacements such as HD-8, if use T6668 can make beeper remember 8 segment informations), IC2 is that DRAM41256(also can replace with 41256 dynamic memors), IC3 is that D2283(also can use KD28, small-power power amplifiers such as LM386 replace), IC4 is that TDA7021T(also can change peripheral circuit slightly, use TDA7010, replacements such as SKA22429), IC5 is the also available ED5027 of YYH28(, decoding circuits such as VD5027 are replaced, and IC6 adopts also available other similar circuit of KD254(to replace).Each battery: E1 is the 6V laminated cell, and E2 is 3.6V, 0.3W solar cell, and E3 is two joint 1.25V cadmium nickel No.5 cell series connection.Each switch: K1, K2 are the fine motion push switch, and K3 is the double-pole self-lock switch.Plug CT1 is that inside and outside core plug, socket CK1 are inside and outside core jack.Parameter, the model of other element of circuit are shown in the following table:
